DESC:FIELD OF INVENTION
This invention relates generally to the field of measuring automotive vehicle parameters such as fuel level in a fuel tank, battery charge level, lubrication oil level, etc. More particularly, this invention relates to a digital system for measuring, monitoring and/or indicating the automotive vehicle parameters such as fuel level in a fuel tank, battery charge level, lubrication oil level, brake fluid level, coolant level in radiator, malfunction indication (MIL), anti-lock braking system (ABS) indication, high rpm indication, any other tell-tale indication,etc. though not limited to these parameters.
BACKGROUND AND PRIOR ARTS
Continuous monitoring of the various automotive vehicle parameters helps in upkeep of vehicle and enables timely action/ maintenance of the vehicle. It is important that various vehicle parameters are monitored continuously and reported to operator for timely actions. Generally these parameters are indicated /reported to operator through a display device.Some of key vehicle parameters include fuel level in a fuel tank, battery charge level, lubrication oil level, brake fluid level, coolant level in radiator, etc. though not limited to these parameters.

For e.g. in all gasoline/gaseous fuel driven vehicles, fuel tank needs to be replenished with fresh fuel periodically when fuel in the fuel tank is exhausted or about to be exhausted. Many operators have practice of re-filing fuel only when limited amount of fuel is available/remainedin the fuel tank. Hence, it is desirable to have continuous real time fuel level indication at the operator’s disposal. For operator convenience, usually the fuel level indication is integrated in display device or speedometer. The fuel level indication provides the operator/driver the approximate information for e.g. whether tank is full, half full, empty or at any intermediate level.

Typically, fuel level or any other liquid levels such as coolant level, lubrication level etc. areindicated in a gauge with a mechanical pointer/needle arrangement integrated with speedometer. Such, mechanical fuel level indication system uses oil damping for keeping the mechanical pointer/needlein its position. However, such mechanical fuel gauges are prone to oil leakage when the vehicle subjected to sudden shocks/jerks for e.g. shocks/jerks experienced when vehicle passes over rough road surfaces. The damping oil gets evaporated due to heat from environment which also reduces accuracy. Further, the mechanical pointer/ needle loses its accuracyover prolonged period of use. With advancement of the technology and to overcome the problems with mechanical fuel level indicators, various types of sensor based level indicators are introduced in vehicles.

In one such exemplary case of fuel level indication, typically, a sensor based fuel level indication system includes a sensor or a sensing system installed in the fuel tank which senses the fuel level and a displaydevice which displays the sensed level to the operator/driver. The sensor used is usually a variable resistance type sensor. However, when the vehicle runs on rough road / steep road, the sudden undesirable movement of fuel in the tank may result in frequent change of resistance and voltage measured by the sensor. This results in frequentfluctuation in fuel level indication and maydisplayincorrect fuel level which is undesirable. To control such fluctuation in fuel level indication, an electronic damping needs to be provided which add cost and complexity.

To keep the cost low, an electronic comparator can be used to provide the required electronic damping. The comparator uses time constant circuit/ RC circuit for electronic damping. In such circuit, capacitor stores electrical energy and releases during damping period/time delay. However, when large time delay needs to be provided, a large capacitor needs to be provided to store/discharge more electrical energy required to provide large time delay. Use of large capacitor leads to higher cost and higher packaging space requirement.

Considering the limitation of the comparator, an exclusivecontrollercan be provided to induce the time delay. Whenthe exclusive controller is added to the fuel level indication system, the input from the sensor or the sensing system is given to the controller which dampens/processes the input and generates a stable signal that is sent to the display. The display indicates the fuel level as per the signal received from the controller. One such arrangement is described in US7305875B1 which uses an exclusive controller to process signal from a fuel level sensor to indicate a fuel level in a fuel tank.

However, to provide a dedicated controller, addition hardware is required for e.g. PCB. Further, to protect controller from voltage fluctuations, additional protection arrangement such as voltage surge suppresser needs to be provided. Thus, providing the exclusive controller leads to requirement of higher packaging space and also increases cost. Similar challenges are faced when sensor controller based system is employed for other vehicle parameter indication.

Usuallyto process the inputs from a fuel level sensor or any other vehicle parameter sensor,a separate controller is provided in a display device or a speedo cluster.This is especially a case when in a display device or in a speedometer, some parameters are shown/ indicated through mechanical means whereas some parameters are displayed digitally.In such situation, for providing separate controller and associated hardware in the display device/the speedo cluster, a space needs to be created in the display device/ the speedo cluster. As the display device/the speedo clusteris already constrained for spacefor e.g. two wheeled vehicles like scooters and motorcycles, small three/four wheeled vehicles, packaging of additional controllerand associated hardware is difficult. Further, use of additional controller leads to increase in cost and complexity of the system. Thus, an alternativedigital parameter indication system which is simpler and less costly is desired.

Yet another object of the invention is to provide a digital parameter indication system which does not require a separate dedicated controller for processing input from the sensor.

Yet anotherobject of the invention is to provide a digital parameter indication system which is simple and less costly.
SUMMARY OF INVENTION
A digital parameter indication system for an automotive vehicle comprising;
aninputmeansfor providing input related to avehicle parameter;
a controller for processing inputreceived from the inputmeans; and
a display for displaying the vehicle parameter to operator;
wherein the controller also controlsat least one other vehicle or engine application.
The controller is distal from the display and not a part of the display.The controller used for vehicle parameter indication along with controlling one or more vehicle or engine applications is not packaged in a display device/speedocluster.

The controller controlling one or more other vehicle or engine applications may include but not limited an ignition control unit, an engine control unit (ECU), a body control module or a brake control module.Further, any other control module in the vehicle may also be suitably adopted for the digital parameter indication system according to invention.

Examples of abovementioned controllers used for other vehicle or engine applications includeignition control through the ignition control unit such as Capacitive Discharge Ignition (CDI) unit, fuel injection control throughthe engine control unit (ECU), various vehicle body controls such as headlights, indicators, horn, switches, engine start, etc. through the body control unit, brake control by the brake control unit such as ABS control unit.

The input means providing input to the controller can be a sensor system which generates signals to be processed by the controller or input can be directly received from a vehicle componentcorresponding to a vehicle parameter to be monitored for e.g.input can be received directly from battery for monitoring and displaying battery charge level.

The digital parameter indication system can be used for indicating automotive vehicleparameterssuch as fuel level, gas (LPG/CNG) level, battery charge level, lubrication oil level, brake fluid level, coolant level in radiator, malfunction indication (MIL), anti-lock braking system (ABS) indication, high rpm indication, side stand indication, high coolant temperature or any other tell-tale indicationsetc. or any combination thereof though not limited to these parameters.

The digital parameter indication system of present invention can be conveniently used in combination with a display device/ speedo cluster where some vehicle parameter/s are indicated by mechanical arrangement whereas some vehicle parameter/s are indicated by the electronic arrangement without increasing cost and requirement of additional packaging space for a separate controller and associated hardware such as PCB, protection device, etc.

According to one of the embodiment of the invention, the digital parameter indication system is used for indication of a fuel level in a fuel tank. The vehicle fuel level indication system according to invention includes a fuel level sensor system, a controller for processing signal from the fuel level sensorand a display for displaying the fuel level to the operator.The vehicle is provided with a Capacitive Discharge Ignition (CDI) unit that controls the ignition activation in the vehicle engine using a controller. Said controller along with ignition control function, also used for processing signal from the fuel level sensor to determine the fuel level and sending signals to the display device to be digitally displayed to the operator. In another aspect of the invention, instead of controller of CDI unit, controller of the engine control unit (ECU), body control module, brake control module or any other control module can also be used.

The sensor system used for measurement of the fuel level is installed in the fuel tank of the vehicle. In one of the embodiments, avariable resistance type fuel level sensor for e.g. wire wound, film resistor, is used to sense the fuel level in the fuel tank. The sensor also includes a float which moves according to change in fuel level in the fuel tank.In such sensor, due to sensor float movement proportional to fuel volume, resistance and voltage changes and the change of resistance and voltage is usedas an input to the controller which processes the input signals from the senor and generate a signal for indicating Fuel Level in the fuel level gaugein speedometer or display device. It is possible to use other type of suitable fuel level sensors in current systemfor e.g. hall sensor, capacitive sensor, reed switch, crank sensor, temperature sensor, side stand switch etc.

When the vehicle runs on rough road / steep road, due to the sudden undesirable movement of fuel in the tank may result in frequent change in sensor output. In such situation the controller helps to provide electronic damping and avoid frequently fluctuating fuel level in display.No separate electronic damping arrangement is provide to negate frequent fluctuationin fuel level. To provide an electronic damping, the controller records a first senor input and after a pre-specified time record a second sensor input. The controller compares the first sensor input with the second sensor input. If the first and second input are same then the fuel level indicated in the display remains unchanged whereas if there is difference, the second input is reflected as a fuel level in the display device. This process of recording and comparing sensor inputs is done by controller on continuous basis during vehicle operation so that correct fuel level is indicated in the display. Use of controller to provide electronic damping further helps in reducing cost and space required.

In one of the embodiment, the display is in the form of LED lights. Five indications namely 100%, 75%, 50%, 25% and reserve fuel volume can be represented by five LEDs. As to provide five different LEDs higher PCB space is required, instead multi colored LED/s can be used where different colours or combination thereofmay represent different fuel levels. For e.g. In one such arrangement, instead of using fifth LED for the reserve volume, a single muti-colour LED that indicates25% fuel level by a green colour and reserve fuel volume by red colourmay be used. Any colour combination can be used for this purpose. Thus instead of using five LEDs in display, only four may be used. This effectively reduces the space required for packaging and cost involved.

In another embodiment of the invention, instead of LED bulbs, other illuminating devices such as low voltage bulbs can be used for indicating vehicle parameters to optimize cost and reduce power consumption from battery for e.g. using 1.7 V bulb which gets ON or OFF to indicate vehicle parameter such as low fuel level, low battery charge level, malfunction indication (MIL), ABS indication, high rpm indication or any other tell-tale indication.

In yet another embodiment, the digital indication system can be used for indicating battery charge level without using a dedicated sensor of detecting battery charge level. In this case the input is directly received from battery. The controller of CDI which control the ignition activation or the engine control unit (ECU) which controls fuel injection orbody control unit which controls various vehicle body controls such as headlights, indicators, horn, switches, engine start, etc. or the brake control unit which control brakescan be directly coupled with a battery to detect battery charge level and send a signal to the display unit to indicate the battery charge level. The battery charge level indication system can be conveniently used with display device/speedo cluster where some parameters are indicated through mechanical means.

In yet another embodiment, the digital parameter indication system can be used for indicating automotive vehicle parameters such as lubrication oil level, brake fluid level, coolant level in radiator, gas (LPG/CNG) level indication, malfunction indication (MIL), ABS indication, high rpm indication,any other tell-tale indication, etc. or any combination thereof though not limited to these parameters using similar arrangement as used for fuel level indication in a display device/speedo cluster where some parameters are indicated using mechanical means and some through digital means.Different type of sensors can be used for sensing the vehicle parameters such as lubrication oil or coolant or brake fluid level in systemof present intention for e.g. variable resistance type sensor, hall sensor, capacitive sensor, reed switch, crank sensor, temperature sensor, side stand switch etc. or combination thereof.

In yet another embodiment, the digital parameter indication system can be used with a separatedigital display for one or more parameters instead ofcombining/integrating it with the display device/speedo cluster indicating some vehicle parameters using mechanical means.

In yet another embodiment, the independent digital display may be disposed on any of the vehicle components for e.g. in saddle type vehicle a separate display may be provided on fuel tank or in four wheeled vehicle, a separate display may be provided on a steering wheel.

The arrangement proposed in the invention helps to eliminate need of providing a separate controller for the various vehicle parameter indication such as fuel level, lubrication oil level, battery charge level, etc. digitally. This helps to reduce the cost. Further, arrangement also eliminates need of extra packaging space to be provided in the display device/ speedo cluster for a separate controller and associated hardware.

The digital parameter indication system may be used in a range of vehicle applications for two, three and four wheelers. It may be used to particular advantage in saddle type vehicle such as motorcycle, scooters, etc.

DETAILED DESCRIPTION
Figure 1 to 5 shows one of the embodiments of a digital fuel indication system according to invention, where the digital fuel indication system isusedfor measuring, monitoring and indicating fuel level in a fuel tank of a vehicle by using a controller of Capacitive Discharge Ignition (CDI) unit.

Referring to Figure 1, the figure shows a side view of a motorcycle 10 with a digital parameter indication system100in accordance with one embodiment of the present invention. The motorcycle 10 includes a frame 30 comprising a head pipe 25, a centre tube 35 extending rearward from the head pipe 25, a down tube 40 extending downwards from the front side of a center tube 35, a central down tube 45 extending downwards from the rear side of a center tube 35 and a seat frame 50 extending rearwards from the rear side of a center tube 35. A fuel tank 55 which carries fuel is mounted on the centre tube 35. A seat 60 is mounted on the seat frame 50. A front wheel 15a and rear wheel 15b is attached to the frame through a front fork and a swing arm respectively.

Referring to figure 2, 3 and 4, a digital parameter indication system 100 according to one of the embodiment of the system is used for indicating a fuel level in the fuel tank 55. The system comprises an input means in the form of a fuel level sensor 70 disposed within the fuel tank 55, a controller 80 provided within a Capacitive Discharge Ignition (CDI) unit 81 and a digital display device 85 integrated with a display device/speedometer 86.The controller 80 is distal from the display device/speedometer 86 and is not part of display device/speedometer 86. The display device/speedometer 86 indicates some parameters for e.g. speed, through mechanical means for e.g.a mechanical pointer/needle arrangement whereas some parameters are indicated digitally through the digital display device 85.When ignition switch 92 is turned on, the CDI unit draws power for its functioning from a battery 90. The battery 90 is mounted on the central down tube 45 using a bracket in proximity of the CDI unit 81. The Battery 90, CDI unit 81, the fuel level sensor 70 and the digital display device 85 are connected together though a wiring harness 95. In another aspect of the invention, battery 90, CDI unit 81, the fuel level sensor 70 and the digital display device 85 can be connected without dedicated wire connection for e.g.using CAN/LIN (Controller AreaNetwork/ Local Interconnect Network) communication.

The fuel level sensor70 used for measurement of the fuel level is installed in the fuel tank of the vehicle. In this embodiment, avariable resistance type fuel level sensor for e.g. wire wound, film resistor, is used to sense the fuel level in the fuel tank. The sensor 70 is connected to inner wall of the fuel tank 55 with the help of a bracket. The sensor 70 also provided with a float 71 which moves up and down as the level of fuel in the tank changes.

Due to the float 71 movement proportional to fuel volume in the fuel tank 55, resistance and voltage signal form the sensor 70 changes and the change of resistance and voltage is used as an input to the controller 80 which processes the input signals from the senor 70 and generate a signal for indicatingthe fuel level in the digital display device 85 in the display device/ speedometer 86. It is possible to use other type of suitable fuel level sensors in current system for e.g. hall sensor, capacitive sensor, reed switch, etc.

The motorcycle 10 is provided with a Capacitive Discharge Ignition (CDI) unit 81 for the ignition control in the engine 12. The controller 80 is integrated in the CDI unit which is pre-programmed for ignition control in engine 12. The same controller 80 also connected to the fuel level sensor 70 in the fuel tank 55. The CDI unit 81 can be conveniently mounted on the frame 30 or any other vehicle component based on the packaging space availability. In the present embodiment, CDI unit is mounted on the central down tube 45.

The input signal from the fuel level sensor 70 is sent to the controller 80 of the CDI unit 81. The controller 80 processes the signal sent by the fuel level sensor 70 and provides required electronicdamping to eliminate frequent fluctuation in fuel level indication. The controller 80 generate signal for the digital display device 85 in the display device/ speedometer 86 to indicate the fuel level in the fuel tank 55.

When the vehicle run on rough road / steep road, due to the sudden undesirable movement of fuel in the tank may result in frequent change in sensor output and fuel level indication.The electronic damping is essential to eliminate frequent fluctuation in fuel level indication. Instead of providing separate electronic damping arrangement, in present invention controller 80 provides electronic damping. To provide electronic damping, the controller 80 records sensor input at a predefined periodic intervals and comparesthem. If the comparison indicates that there is change in fuel level, same in reflected in the digital display device 85 and frequent change in fuel level indication is avoided.

Referring to figure 4, the display device/speedo cluster 86 includes a housing155 which forms a cavity to accommodate the hardware associated with various parameter indication for e.g. mechanical gearing arrangement, PCB, wiring, etc.The display device/speedo cluster 150 indicate some vehicle parameter using mechanical means for e.g. a needle/pointer and some parameters using digital means for e.g. LED’s.A dial 160 is provided in the housing such that it covers the cavity of the housing. The dial 160 is graduated to indicate the units of values of the parameter to be indicated through mechanical means. For instance, in case speed of thevehicle is to be indicated, the dial is graduated in units of kilometersper hour or miles per hour. A transparent cover 170 is disposed over the dial.The housing is mounted on thehandlebar (not shown) of a two wheeler vehicle or dashboard (not shown) of a three wheel or four wheel vehicle by securing screws (not shown) through a suitablefastening arrangement.

The digital display device 85 is integrated on the dial 160 of the display device/speedo cluster 150. The digital display device 85 is in the form of series of LED lights 180. Five indications namely 100%, 75%, 50%, 25% and reserve fuel volume can be represented by four LEDs 180a, 180b, 180c and 180d. The last LED 180d is a multi-coloured LED where different colours or combination thereof may represent different fuel levels. For e.g. single muti-colour LED 180d indicates 25% fuel level by a green colour and reserve fuel volume by red colour. Any colour combination can be used for this purpose. Use of multi-coloured LED helps to reduce number of LED used for indication. Further, this also reduces the space required for packaging and cost involved.

Figure 5 shows a sequential operation of the digital parameter indication system for indicating fuel level at various stages of fuel level in the fuel tank according to present invention. All values, including resistance and voltage values represented in figure are representative and may change based on design requirement.When the ignition switch 92 is turned on, power supply starts to CDI unit 81. At the ignition all LEDs 180a, 180b, 180c, 180d (only green) switches turn on for a predefined time for e.g. 2 sec.Power to the controller 80 is supplied through CDI unit 81. Resistance and voltage signal are generated by the fuel level sensor 70 continuously and sent to the controller 81 through the wiring harness 95. Based on the signal from the fuel level sensor 70, when the fuel level is full (100%), all LEDs 180a, 180b, 180c, 180d (green) are switched on and 180d (red) is off. When the fuel level reaches three fourth (75%) level, LEDs 180b, 180c, 180d (green) are switched on and 180a and 180d (red) is off. When the fuel level reaches to half (50%), LEDs 180c, 180d (green) are switched on and 180a, 180b and 180d (red) is off. When the fuel level reaches to one fourth (25%), LEDs 180d (green) are switched on and 180a, 180b, 180c and 180d (red) is off. When the fuel level reaches to less than one fourth (less than 25%), LEDs 180d (red) are switched on and 180a, 180b, 180c and 180d (green) is off. When the fuel tank 55 gets empty, all LEDs 180a, 180b, 180c, 180d are switched off.

Referring to figure 6, in yet another embodiment, a separate digital display 300 is provided on the top of the fuel tank 55a instead of combining/integrating it with the display device/ speedo cluster indicating some vehicle parameters using mechanical means. The separate digital display 300 may be used for indicating parameters such as fuel level, lubrication oil level, brake fluid level, coolant level in radiator, etc. or any combination thereof though not limited to these parameters using similar arrangement as used for fuel level indication. Further, the independent digital display may be disposed on any of the vehicle components for e.g. in saddle type vehicle a separate display may be provided on handle bar or in four wheeled vehicle, a separate display may be provided on a steering wheel.

The digital parameter indication system described in specification can be suitably adopted for indicating automotive vehicle parameters such as lubrication oil level, brake fluid level, coolant level in radiator, malfunction indication (MIL), ABS indication, high rpm indication, any other tell-tale indication,etc. or any combination thereof though not limited to these parameters using similar arrangement as used for fuel level indication.Further, the digital parameter indication system can be adopted using various controllers which manages one or more vehicle or engine applications such as the ignition control unit that controls ignition, engine control unit (ECU) that controls fuel injection, the body control unit that controls various vehicle body controls such as headlights, indicators, horn, switches, engine start, etc. or the brake control unit that controls brakes.Different type of sensors can be used for sensing the vehicle parameters such as lubrication oil or coolant or brake fluid level, in systemof the invention for e.g. variable resistance type sensor, hall sensor, capacitive sensor, reed switch, crank sensor, temperature sensor, side stand switch, etc. or combination thereof for adoption of the digital parameter indication system according to the invention.

The arrangement proposed in the invention helps to eliminate need of providing a separate controller for the vehicle parameter indication system digitally. This helps to reduce the cost. Further, arrangement also eliminates need of extra packaging space to be provided in the display device/ speedo cluster for a separate controller and associated hardware.

The digital parameter indication system may be used in a range of vehicle applications for two, three and four wheelers. It may be used to particular advantage in saddle type vehicle such as motorcycle, scooters, etc.
