Description:FIELD OF THE INVENTION
[001] Present invention relates to a system and a method for operating a lamp unit of a vehicle.

BACKGROUND OF THE INVENTION
[002] It is a known fact that, vehicles are equipped with lamp units. The lamp units are provided at a front portion and a rear portion of the vehicle. The lamp units provided at the front portion are headlamp units, which are adapted to illuminate surroundings in front of the vehicle for enhancing visibility to a rider of the vehicle. The lamp units provided at the rear portion of the vehicle are brake indicator lamp units which are adapted to illuminate in response to application of a brake lever by the rider of the vehicle. The brake indicator lamp units are generally illuminated continuously through actuation of a switch coupled to the brake lever. Upon application of the brake lever sufficient to actuate the switch, the brake indicator lamp units illuminate continuously until the brake application is released sufficiently to de-actuate the switch, such as when brake lever is entirely released. Illumination of the brake indicator lamp units alert other trailing drivers, that the vehicle is decelerating or stopping. The brake indicator lamp units thus prevent possible rear-end collisions and enhance safety.
[003] In recent past, to enhance rider convenience, features such as a cruise control system and the like are provided in the vehicle. The cruise control system is an electronic system, that allows the vehicle to maintain a specific speed (i.e. cruising speed) without requiring the rider to manually control an accelerator pedal of the vehicle. In other words, the cruise control system is an autopilot mode for the vehicle which ensures a steady pace on roads.
[004] Further, the cruise control system is also adapted to monitor its surroundings. Thus, in the event of an obstruction along a travelling path of the vehicle, the cruise control system applies a negative torque (which can be through engine braking) for decelerating or stopping the vehicle, to prevent a collision. However, as the deceleration by the cruise control system is through the negative torque (i.e. by engine braking), the brake indicator lamp units are in an idle or in an inoperable condition. As such, when the brake indicator lamp units are not illuminated, the trailing vehicle may not realize the deceleration or slowing down of the vehicle. Such a scenario may cause the trailing vehicle to collide with the vehicle, which may prove to be catastrophic. Such a situation is more pronounced while driving in low light or night driving conditions.
[005] Thus, there is a need for a system and a method for actuating a lamp unit of a vehicle which addresses at least the aforementioned problems.

[021] In an embodiment, the throttle position sensor 104b is mounted to a throttle body (not shown) of the prime mover being the IC engine. The throttle body is typically a throttle valve such as a butterfly valve located between an air intake filter and an air intake manifold. The throttle body regulates an amount of air intake into the IC engine based on an input from the rider obtained through an accelerator pedal (not shown) of the vehicle. The throttle position sensor 104b is adapted to procure information pertaining to a throttle position of the throttle body in the vehicle. The term “throttle position” may be defined as a degree of opening of the throttle body. In an embodiment, the throttle position sensor 104b may be a potentiometer-based sensor, a Hall effect sensor, and the like. In an embodiment, the throttle position sensor 104b may be connected to the accelerator pedal and determines the degree of actuation of the accelerator pedal by the rider for enabling supply of electric current from a battery pack (not shown) to the electric motor. The throttle position sensor 104b is adapted to procure information pertaining to actuation of the throttle member. As such, the throttle position sensor 104b is adapted to procure information pertaining to percentage of the throttle opening of the throttle member.
[022] In an embodiment, the RPM sensor 104c is coupled to a crankshaft of the IC engine or to a motor shaft of the electric motor. The RPM sensor 104c is adapted to procure information pertaining to the operating speed of the prime mover of the vehicle.

The brake switch sensor 104d is adapted to procure information pertaining to activation of the brake lever by the rider. The brake switch sensor 104d may be a switch member that is adapted to be operated to an ON position when the brake lever is applied or actuated by the rider, and operated to an OFF position when the brake lever is released by the rider. In an embodiment, the brake switch sensor 104d may be one of a potentiometer-based sensor, a magneto-resistive sensor and the like.
[024] Further, the system 100 comprises a control unit 102 that is disposed in the vehicle and is communicably coupled to each of the one or more sensors 104. In an embodiment, the control unit 102 is communicably coupled to each of the one or more sensors 104 using conducting wires or through wireless communication techniques known in the art. The control unit 102 is configured to receive information pertaining to the one or more vehicle parameters from the one or more sensors 104. Basis the information received from the one or more sensors 104, the control unit 102 is adapted to determine the one or more vehicle parameters. In an embodiment, the control unit 102 can be a Vehicle Control Unit (VCU). In an embodiment, the control unit 102 is disposed within the infotainment system 108.
[025] In an embodiment, the control unit 102 on receiving the information pertaining to the speed of the vehicle (i.e. rate of rotation of the front wheel and/or the rear wheel) from the vehicle speed sensor 104a, determines the speed of the vehicle. In an embodiment, the control unit 102 on receiving the information pertaining to the throttle position of the throttle body (i.e., degree of opening of the throttle body) from the throttle position sensor 104b, determines the throttle position of the throttle body in the vehicle. In an embodiment, the control unit 102 on receiving the information (i.e., frequency of rotation of the crankshaft or motor shaft) from the RPM sensor 104c, determines the operating speed of the prime mover. In an embodiment, the control unit 102 on receiving the information pertaining to activation of the brake lever (i.e., an extent of displacement of the brake lever from its original position by the rider) from the brake switch sensor 104d, determines the state of the switch member.
[026] Further, the control unit 102 is communicably coupled with the prime mover and is capable of controlling operation of the prime mover, corresponding to riding requirements of the rider. In an embodiment, the control unit 102 is configured to operate the prime mover in a cruise control mode. The cruise control mode is an operating mode in the vehicle, wherein the control unit 102 controls the prime mover to operate the vehicle at a rider selected cruising speed. As an example, if the rider has selected the cruising speed of the vehicle to be 60 kmph, the control unit 102 upon determining selection of the cruise control mode by the rider is adapted to operate the prime mover to ensure that the vehicle is riding at 60 kmph. In an embodiment, the rider can select or activate the cruise control mode by navigating through the instrument cluster 108 of the vehicle. The rider may use a display (not shown) on the instrument cluster 108 or a keypad (not shown) on the handlebar for navigating through the instrument cluster 108 for selecting the cruise control mode. The control unit 102 during the cruise control mode is configured to apply a negative torque, which can be through engine braking, when an obstacle is determined by the control unit 102. In an embodiment, the control unit 102 is adapted to enable engine braking by reducing volume of charge (i.e. fuel and/or air) into the IC engine or by shifting to a lower gear in the transmission unit or by reducing the amount of electric current supplied to the electric motor.
[027] The control unit 102 is also communicably coupled with the lamp unit 106. The control unit 102 is adapted to operate the lamp unit 106 for illumination, when the brake lever is actuated or pressed by the rider. The control unit 102 is also adapted to operate the lamp for illumination, when the one or more vehicle parameters is beyond a threshold value. As such, irrespective of whether the brake lever is actuated by the rider or whether deceleration is due to the engine braking by the control unit 102 in the cruise control mode, the system illuminates the lamp unit 106 for indicating vehicle deceleration. In an embodiment, the control unit 102 provides a signal to a battery pack (not shown) for supplying electric current to the lamp unit 106 for illumination, when the brake lever is actuated by the rider or when the one or more vehicle parameters is beyond the threshold value. It is pertinent to note that, the term “is beyond the threshold value” corresponds to the one or more vehicle parameters or other related parameters such as rate of deceleration of the vehicle can be below the threshold value or above the threshold value based on the parameter considered.
[028] In an embodiment, the control unit 102 is adapted to illuminate the lamp unit 106, when a sudden decrease in the vehicle speed is detected. As such, in the present embodiment, the control unit 102 illuminates the lamp unit 106 when the vehicle speed is below the threshold value. As an example, if the vehicle speed is determined to be 40 kmph and in the next instance, when the control unit 102 determines the vehicle speed to be 30 kmph, the control unit 102 is adapted to comprehend this scenario to be a braking event, and thus illuminate the lamp unit 106.
[029] In an embodiment, the control unit 102 is adapted to illuminate the lamp unit 106, based on the throttle position and decrease in the vehicle speed. As such, in the present embodiment, the control unit 102 illuminates the lamp unit 106 when the throttle position or opening and the vehicle speed are below the threshold value. As an example, if the throttle member is suddenly disengaged, and decrease in vehicle speed is determined by the control unit 102, the lamp unit 106 is illuminated.
[030] In an embodiment, the control unit 102 is adapted to illuminate the lamp unit 106, based on the throttle position, speed of the prime mover and decrease in the vehicle speed. As such, in the present embodiment, the control unit 102 illuminates the lamp unit 106 when the throttle position, speed of the prime mover (RPM of prime mover) or opening and the vehicle speed are below the threshold value. As an example, if the throttle member is suddenly disengaged, and decrease in vehicle speed and speed of prime mover is determined by the control unit 102, the lamp unit 106 is illuminated.
[031] In an embodiment, the control unit 102 is adapted to illuminate the lamp unit 106, when a rate of decrease in the vehicle speed is below the threshold limit during the cruise control mode. As an example, considering that the vehicle is travelling at the vehicle speed of 40 kmph in the cruise control mode and the threshold rate of decrease in the vehicle speed is 1 kmph per second, if the control unit 102 determines the vehicle speed to be 35 kmph in the next second (i.e. rate of decrease in vehicle speed is 5 kmph per second), the lamp unit 106 is illuminated. In an embodiment, the control unit 102 is adapted to operate the lamp unit 106 in a controlled manner (or the illumination of the lamp unit 106 is sustained and unflickered) when the one or more vehicle parameters is below the threshold value.
[032] In an embodiment, the control unit 102 is embodied as a multi-core processor, a single core processor, or a combination of one or more multi-core processors and one or more single core processors. For example, the control unit 102 is embodied as one or more of various processing devices, such as a coprocessor, a microprocessor, a controller, a digital signal processor (DSP), a processing circuitry with or without an accompanying DSP, or various other processing devices including integrated circuits such as, for example, an application specific integrated circuit (ASIC), a field programmable gate array (FPGA), a microcontroller unit (MCU), a hardware accelerator, a special-purpose computer chip, or the like. In another embodiment, the control unit 102 is configured to execute hard-coded functionality.
[033] Figure 2 is a flow diagram of a method 200 for operating the lamp unit 106, in accordance with an exemplary embodiment of the present invention. The method 200 is implemented by the system, such as the system 100. Particularly, the method 200 is implemented by the control unit 102 of the system 100.
[034] At step 202, the control unit 102 is adapted to determine an ignition ON condition of the vehicle. In an embodiment, the ignition ON condition of the vehicle refers to firing of or turning ON of the prime mover. In an embodiment, the control unit 102 may be communicably coupled to an ignition sensor (not shown), that is adapted to provide information pertaining to electric current supplied to a spark plug of the engine. Based on the information received from the ignition sensor, the control unit 102 determines the ignition ON condition of the vehicle. In an embodiment, the control unit 102 may be communicably coupled to the battery pack, wherein the control unit 102 is adapted to monitor discharge of electric current to the electric motor. On detecting supply of the electric current to the electric motor, the control unit 102 may be adapted to determine the ignition ON condition of the vehicle.
[035] At step 204, the control unit 102 identifies if the cruise control mode is selected by the rider. The rider may select the cruise control model through the instrument cluster.
[036] At step 206, the control unit 102 is adapted to determine if the one or more vehicle parameters are beyond the threshold value. In the present embodiment, the one or more vehicle parameters is rate of deceleration of the vehicle and the vehicle speed. The control unit 102 determines if the rate of deceleration or deceleration of the vehicle is greater than the threshold value, and if the vehicle speed is greater than the threshold value. As an example, considering that the vehicle is travelling at the vehicle speed of 40 kmph in the cruise control mode and the threshold rate of decrease in the vehicle speed is 1 kmph per second, if the control unit 102 determines the vehicle speed to be 35 kmph in the next second, the rate of decrease in the vehicle speed is determined to be 5 kmph per second. Accordingly, the control unit 102 determines that the vehicle deceleration is greater than the threshold value. Also, if the threshold speed is set to be 25 kmph and the control unit 102 determines the vehicle speed to be 30 kmph, the control unit 102 determines the vehicle speed to be greater than the threshold value.
[037] At step 208, the control unit 102 is adapted to provide lamp actuation signal or lamp operating signal to the instrument cluster 108 or a Load Control Module (LCM) or a Body Control Module (BCM), over a Controller Area Network (CAN). At this scenario, the control unit 102 moves to step 210, wherein the instrument cluster 108 operates or actuates the lamp unit 106 for illumination. In an embodiment, the control unit 102 provides an operating signal to the battery pack through the instrument cluster 108, thereby enabling supply of electric current to the lamp unit 106 for illumination.
[038] Figure 3 is a flow diagram of a method 300 for operating the lamp unit 106, in accordance with an exemplary embodiment of the present invention. In the present embodiment, the control unit 102 is adapted to directly actuate the lamp unit 106, that is without the intervention or using the instrument cluster 108. The method 300 is implemented by the system, such as the system 100. Particularly, the method 300 is implemented by the control unit 102 of the system 100.
[039] At step 302, the control unit 102 is adapted to determine the ignition ON condition of the vehicle. On detecting ignition ON condition of the vehicle, the control unit 102 moves to step 304.
[040] At step 304, the control unit 102 identifies if the cruise control mode is selected by the rider. The rider may select the cruise control model through the instrument cluster.
[041] At step 306, the control unit 102 is adapted to determine if the one or more vehicle parameters are beyond the threshold value. In the present embodiment, the one or more vehicle parameters is rate of deceleration of the vehicle and the vehicle speed. The control unit 102 determines if the rate of deceleration or deceleration of the vehicle is greater than the threshold value, and if the vehicle speed is greater than the threshold value.
[042] At step 308, the control unit 102 is adapted to operate the lamp unit 106, by enabling supply of electric current to the lamp unit 106 for illumination. Thus, enable illumination of the lamp unit 106 even when the vehicle is being operated in the cruise control mode.
[043] Figure 4 is a method 400 for operating the lamp unit 106 of the vehicle, in accordance with an exemplary embodiment of the present invention. The method 400 is also implemented by the system, such as the system 100. Particularly, the method 400 is implemented by the control unit 102 of the system 100.
[044] At step 402, the control unit 102 receives information pertaining to one or more vehicle parameters. The control unit 102 receives the information pertaining to one or more vehicle parameters through one or more sensors 104 as already described in description pertaining to Figure 1.
[045] At step 404, the control unit 102 determines the one or more vehicle parameters based on the information provided by the one or more sensors 104. Subsequently, at step 406, the control unit 102 operates the lamp unit 106 for illumination when the one or more vehicle parameters is beyond a threshold value, as already described in description pertaining to Figure 1.

Specifically, the claimed aspect of the system the control unit being capable of determining the one or more vehicle parameters and operating the lamp unit when the one or more vehicle parameters is beyond the threshold value, not only illuminates the lamp unit during application of brake lever but also during negative torque application when the vehicle is operating in the rider assistant mode such as the cruise control mode. Consequently, safety and comfort of the rider and/or the passengers in the vehicle are enhanced.
