Specification

Description:TECHNICAL FIELD
[0001] The present subject matter generally relates to system and method for controlling an idle start stop system.
BACKGROUND
[0002] Generally, present day automobiles are equipped with idle stop start (ISS) feature that automatically turn-off an engine in a state of vehicle idling. Specifically, in IC engines, combustion of fuel does not take place steadily and varies at intervals of time based on the automobile throttle state. An idling state occurs when such an engine is kept running when the vehicle is not in use or in a standstill position while parking. Vehicle idling results in unnecessary consumption of fuel by the engine and emission of harmful gases into the environment. To overcome this, a system to effectively control the engine during idling is placed in such automobiles. Reducing the amount of energy wasted in idling conditions especially at heavy traffic zones significantly helps in gaining better fuel economy for vehicles.
[0003] The current idle start stop system comprises of an idle start stop controller. The idle start stop controller requires inputs from at least a braking signal, and a throttle signal. The idle start stop controller engages the integrated starter generator upon receiving inputs of the braking signal, and the throttle signal. For example, if a user is operating the vehicle, and is momentarily in an idle condition, the idle start stop feature will turn-off the engine. The user may restart the engine by an application of brakes and throttle, achieving safe restart of the engine and avoiding sudden actuation of the vehicle, therefore, avoiding head-on collisions. Moreover, for indication of application of brakes to other users, one or more braking lights are switched on when a brake lever is operated. In the current idle start stop system, the switching on of the one or more braking lights is given as the braking signal input to the idle start stop controller. Therefore, if the one or more braking lights are switched on, and the user has applied throttle to the vehicle engaging the throttle switch, the idle start stop controller will operate the integrated starter generator, which will restart the engine of the vehicle.
[0004] Conventionally, in the brake lever of a vehicle, there is some free-play in the brake lever. This free-play is a measurement of how far the lever of the braking system moves before a master cylinder first begins to apply. The free-play in the brake lever is necessary to ease the strain on the brakes of the vehicle, as well as avoids jamming of the brakes. However, this free-play of the brake lever may increase due to irregular servicing, aging of the vehicle, or general wear and tear of the vehicle. Therefore, there could be a possibility that the braking lights are switched on but mechanically the brake is not engaged in the vehicle. This is due to the free-play being increased to a brake lever travel distance which is more than the brake lever travel distance needed to switch on the one or more braking lights. Since the idle start stop controller receives input of the braking signal from the switching on of the braking lights, the idle start stop controller may actuate the integrated starter generator, in the case of the user unintentionally applying the throttle to the vehicle. Thus, leading to potential safety risk of collisions and accidents, endangering the health and safety of the user.
[0005] In a conventional vehicle, the free-play range of a brake lever of a vehicle is calculated as an angular measurement between a rest position of the brake lever and a position at which the brakes are applied when the lever has travelled a pre-determined distance. The rest position of the brake lever is defined as a position at which the brake lever is not being operated.
[0006] Generally, this free-play range lies in an angular range of 8 degrees to 10 degrees. This free-play of the brake lever can increase up to 20 degrees upon poor servicing and poor maintenance issues. Therefore, on operating the brake lever such that the angle formed between the distance travelled by the brake lever and the rest position is 8 degrees to 10 degrees, the master cylinder begins to apply. For example, if the one or more braking lights are switched on at a distance such that the angle formed between the rest position of the brake lever and the distance travelled by the lever is 10 degrees, the braking signal is received by the idle start stop controller, and the idle start stop controller operates the integrated starter generator, which starts the engine of the vehicle. Now for example, if the free-play of the brake lever increases due to problems such as irregular servicing, aging of the vehicle, or general wear and tear of the vehicle, to an angle of 20 degrees. The one or more braking lights will switch on at 10 degrees, however the activation of mechanical brakes to the vehicle will occur only when the angle is more than 20 degrees. Therefore, due to the switching on of the one or more braking lights, the idle start stop feature will operate, and cause sudden starting of the vehicle, if the user unintentionally applies throttle to the vehicle. Therefore, this poses huge danger to the user of the vehicle and increases the probability of head-on collisions and accidents.
[0007] Moreover, the one or more braking lights of the vehicle are switched on in events when there is a non-application of brakes. This leads to drainage of battery and incorrect indication to the other users on road.
[0008] Due to the contradictory nature of using activation of the one or more braking lights, where such activation is used to start the engine of the vehicle using the idle start stop feature, as well as to apply mechanical brakes to the vehicle, there is an increased risk of collisions and jeopardizing safety of users, even risking additional collateral damage of other people. The dual function of the activation of the one or more braking lights is an inefficient and dangerous use for the idle start stop feature.
[0009] More specifically, the problem arises in setting independent actuation of the idle start stop system, ensuring that the idle start stop system actuates the engine of the vehicle only when the brakes are mechanically applied to the vehicle by the user, and then operating the engine of the vehicle.
[00010] Furthermore, in the above-mentioned vehicle, since the free-play of the brake lever increases due to complications caused by irregular servicing, aging of the vehicle, or general wear and tear of the vehicle, there can also be a delay in switching on of the one or more braking lights in the vehicle. This delay will fail to provide indication to other users that the user of the vehicle intends to stop the vehicle, and therefore, leading to life-threatening accidents and collateral damage.
[0009] Thus, there is a need in the art for a method and a system for an idle start stop system of a vehicle which addresses at least the aforementioned problems and other problems of known art.
[00011] Further limitations and disadvantages of conventional and traditional approaches will become apparent to one of skill in the art, through comparison of described systems with some aspects of the present disclosure, as set forth in the remainder of the present application and with reference to the drawings.

DETAILED DESCRIPTION
[00024] Exemplary embodiments are described with reference to the accompanying drawings. Wherever convenient, the same reference numbers are used throughout the drawings to refer to the same or like parts. While examples and features of disclosed principles are described herein, modifications, adaptations, and other implementations are possible without departing from the spirit and scope of the disclosed embodiments. It is intended that the following detailed description be considered as exemplary only, with the true scope and spirit being indicated by the following claims.
[00025] An objective of the present subject matter is to provide an idle start stop system which comprises of at least an idle start stop controller, an integrated starter generator, a throttle switch, a brake lever. The brake lever is configured with a brake switch system. The brake switch system is configured to actuate at a first distance and a second distance. The first distance is a first pre-determined travel distance of said brake lever, and the second distance is a second predetermined travel distance of said brake lever. The brake switch system is configured to send braking signal to said idle start stop controller at the second distance.
[00026] As per an aspect of the present subject matter, the brake switch system is configured to switch on one or more brake signal lamps at the first distance. In an embodiment, the one or more brake signal lamps are switched on before the brakes are applied in the vehicle. This application of brakes is delayed by a miniscule time difference. This accurately indicates to other users on the road that brakes are being applied in the vehicle.
[00027] As per an aspect of the present subject matter, the idle start stop controller is configured to receive inputs from a throttle switch. The throttle switch is configured to apply throttle to a vehicle. As per another aspect of the present subject matter, the idle start stop system also comprises of an integrated starter generator. The idle start stop system controller takes an input from the brake switch and the throttle switch. Once the inputs are received by the idle start stop controller, the idle start stop controller operates the integrated starter generator. The integrated starter generator starts the engine of the vehicle. For example, if a user is operating the vehicle, and is momentarily in an idle condition, the idle start stop feature will turn-off the engine. The user may restart the engine by an application of brakes and throttle together, achieving safe restart of the engine and avoiding sudden actuation of the vehicle, therefore, avoiding head-on collisions. The present invention ensures that the mechanical application of brakes has been actuated, and eliminates the use of switching on of braking lights as an input to the idle start stop controller. Therefore, this eliminates the possibility that the braking lights are switched on but mechanically the brake is not engaged in the vehicle. The idle start stop controller receives input of the braking signal based on the independent braking signal, which the idle start stop controller considers for actuation of the integrated starter generator. The present invention, therefore, safeguards the user’s safety when unintentionally applying the throttle to the vehicle.
[00028] As per an aspect of the present subject matter, the brake switch system comprises of a single switch. The single switch is configured to switch on the one or more braking lights at the first distance, and the single switch is configured to send the braking signal at the second distance. The use of a single switch will eliminate the need of additional parts and make the novel idle start stop system being disclosed in the present subject matter easy to assemble in existing vehicles.
[00029] As per another aspect of the present subject matter, the brake switch comprises of a first switch, and a second switch. The first switch is configured to switch on the one or more braking lights at the first distance, and the second switch is configured to send the braking signal at the second distance.
[00030] As per an aspect of the present subject matter, the first distance is a first pre-determined travel distance of said brake lever, and the second distance being a second predetermined travel distance of said brake lever.
[00031] The first pre-determined travel distance of the brake lever and the second pre-determined travel distance of the brake lever of a brake lever of a vehicle is calculated as an angular measurement between a rest position of the brake lever and a position at which the brake lever has travelled. The rest position of the brake lever is defined as a position at which the brake lever is not operated.
[00032] The free travel range of the brake lever is free movement of the brake lever before actuating the brake switch system. As per an embodiment, the free travel range of the brake lever lies in an angular range of 8 degrees to 10 degrees. Therefore, as per the embodiment, on operating the brake lever such that the angle formed between the lever position after travelling a distance and the rest position is 8 degrees to 10 degrees, then the master cylinder begins to apply.
[00033] As per an aspect of the present subject matter, the first distance is more than the second distance.
[00034] As per an aspect of the present subject matter, the angle formed between the rest position of said brake lever, and the position of the brake lever after travelling a second distance being in angular range of 30 degrees to 60 degrees.
[00035] As per an aspect of the present subject matter, the first distance is more than free travel range of the brake lever. The angle formed between the rest position of the brake lever, and the position of the brake lever after travelling the first distance being less than an angular range of 30 degrees to 45 degrees.
[00036] As per an aspect of the present subject matter, the angle formed between the rest position of the brake lever, and the position of the brake lever after travelling the first distance being in an angular range of 10 degrees to 30 degrees.
[00037] For simplicity, the following working example can be taken into consideration. When the angle formed between the rest position of the brake lever and the position of the brake lever after distance travelled by the brake lever is more than 10 degrees, the brake switch system switches on the one or more braking lights. When the angle formed between the rest position of the brake lever and the position of the brake lever after distance travelled by the lever is more than 30 degrees, the brake switch system is configured to send the braking signal to the idle start stop controller. Upon receiving signals from the throttle switch and the brake switch system, the idle start stop controller operates the integrated starter generator. The integrated starter generator starts the engine of the vehicle.
[00038] The present invention eliminates the idle start stop feature operating due to not accurately receiving the braking signal of the vehicle. Therefore, the present invention avoids the sudden starting of the vehicle if the user unintentionally applies throttle to the vehicle.
[00039] In view of the above, the claimed limitations as discussed above are not routine, conventional, or well understood in the art, as the claimed limitations enable the above solutions to the existing problems in conventional technologies.
[00040] The present subject matter is described using an idle start stop system which is used in a vehicle, whereas the claimed subject matter can be used in any other type of application employing above-mentioned idle start stop system, with required changes and without deviating from the scope of invention. Further, it is intended that the disclosure and examples given herein be considered as exemplary only.

[00042] The embodiments of the present invention will now be described in detail with reference to a battery pack along with the accompanying drawings. However, the present invention is not limited to the present embodiments. The present subject matter is further described with reference to accompanying figures. It should be noted that the description and figures merely illustrate principles of the present subject matter.

Moreover, all statements herein reciting principles, aspects, and examples of the present subject matter, as well as specific examples thereof, are intended to encompass equivalents thereof.
[00043] Figure 1 exemplarily illustrates general view of handlebar assembly indicating positioning of brake lever in accordance with an embodiment of the present disclosure. The vehicle depicted is a vehicle with a handlebar. However, the implementation is not limited to it but may be feasible in a scooter type vehicle, saddle type vehicle, a straddle type vehicle, a three-wheeler, a multi-wheeled vehicle etc. When the brake lever is not being operated, the brake lever (101) is at a rest position (105). In an embodiment, the brake lever (101) can be a plunger.
[00044] The brake lever (101) actuates one or more brake signal lamps (205) after travelling a first distance (104). The brake lever (101) forms a first angle (104a) with the rest position (105) after travelling the first distance (104). The brake lever (101) actuates a brake switch system (201, refer figure 2) after travelling a second distance (103). The brake lever (101) forms a second angle (103a) with the rest position (105) after travelling the second distance (103). In an embodiment, the brake signal lamps (205) are switched on a minuscule amount of time before the mechanical actuation of brakes of the vehicle.
[00045] The first distance (104) and the second distance (103) are a pre-determined travel distance of the brake lever (101). The first distance (104) is less than the second distance (103). Further, the first angle (104a) is less than the second angle (103a). The second distance (103) being such that the second angle (103a) formed is in the angular range of 30 degrees to 60 degrees.
[00046] Further, the first distance (104) being such that the first angle (104a) formed is less than the angular range of 30 degrees to 45 degrees. Further, the first distance (104) being such that the first angle (104a) formed is in the angular range of 10 degrees to 30 degrees.
[00047] Further, where the first distance (104) is more than a pre-determined free travel range (not shown) of the brake lever (101). The pre-determined free travel range (not shown) of said brake lever (101) being free movement of the brake lever (101) before actuating the brake switch system (201, refer figure 2).
[00048] Further, throttle switch (106) is configured to apply throttle to a vehicle in which the present invention is applicable.
[00049] Figure 2 exemplarily illustrates a block diagram of idle start stop system in accordance with an embodiment of the present disclosure. The brake switch system (201) is configured to actuate the one or more brake signal lamps (205) and the idle start stop controller (202). The brake switch system (201) actuates the one or more brake signal lamps (205) when the brake lever (101) travel the first distance (104). The brake switch system (201) actuates the idle start stop controller (202) when the brake lever (101) travel the second distance (103). Moreover, the idle start stop controller (202) is configured to take inputs from the brake switch system (201) and the throttle switch (106). The idle start stop controller (202) operates the integrated starter generator (203) once idle start stop controller (202) has received signals from the brake switch system (201) and the throttle switch (106), which in turn operates an engine of a vehicle in which the present invention is applicable. This eliminates the use of switching on of the one or more brake signal lamps (205) as an input for the idle start stop controller (202), which increases the possibility of accidental starting of a vehicle.
[00050] Figure 3 exemplarily illustrates a brake switch system when brake lever is in a resting position in accordance with an embodiment of the present disclosure. Figure 4 exemplarily illustrates a brake switch system when brake lever in first distance in accordance with an embodiment of the present disclosure. Figure 5 exemplarily illustrates a brake switch system when brake lever in second distance in accordance with an embodiment of the present disclosure. For brevity, figures 3, 4, and 5 will be explained together. In figure 1, the brake switch system (201) is shown when the brake lever (101) is in the rest position (105). Therefore, no switches are actuated or operated. In figure 2, the brake switch system (201) is shown when the brake lever (201) is in the first distance (104). The brake switch system (201) actuates the one or more brake signal lamps (205) by creating a closed circuit at a first electrical contact breaker (302) and a second electrical contact breaker (303). The first electrical contact breaker (302) actuates the one or more brake signal lamps (205) and the second electrical contact breaker (303) actuates the mechanical brakes (not shown) of a vehicle (not shown). In figure 3, the brake switch system (201) is shown when the brake lever (101) in in the second distance (103). The brake switch system (201) sends a braking signal to the idle start stop controller (202) by creating a closed circuit at a third electrical contact breaker (304). Therefore, the braking signal is sent to the idle start stop controller (202) when the brakes are applied, and eliminating the risk of using the switching on of the one or more brake signal lamps (205) as an input for the idle start stop controller (202), therefore, avoiding the possibility of accidental starting of a vehicle. In an embodiment, the brake switch system (201) can be a single switch that actuates the one or more brake signal lamps (205) and send braking signal to the idle start stop controller (202). In another embodiment, the brake switch system (201) can be a first switch that actuates the one or more brake signal lamps (205) and a second switch that sends braking signal to the idle start stop controller (202).
[00051] Figure 6 exemplarily illustrates a flowchart of method of operation of ideal start stop system in accordance with an embodiment of the present disclosure. The method initiates the process at step 601. At step 602, the brake lever (101) is operated to actuate a brake switch system (201) at a first distance (104) and a second distance (103). At step 603, the brake switch system (201) switches on the one or more brake signal lamps (205) at the first distance (104). At step 603, the brake switch system (201) sends a braking signal to an idle start stop controller (202) at the second distance (103) to actuate idle start stop system.
[00052] At step 605, the idle start stop controller (202) receives inputs from a throttle switch (106). At step 606, the idle start stop generator (202) operates an integrated starter generator (not shown) upon receiving inputs from the brake switch system (201). The method terminates at step 606.
[00053] Figure 7 exemplarily illustrates a test results depicting the lever travel and actuation of idle start stop system in accordance with an embodiment of the present disclosure. On the Y axis is depicted the lever travel distance of the brake lever (101) and on the X axis is depicted the brake lever (101) load. A primary slope (704) depicts the free travel range of the brake lever (101) which is the free movement of the brake lever (101) before actuating the brake switch system (201). A secondary slope (705) depicts the actuation of brakes and sending the braking signal to the idle start stop controller (202). At 701, the one or more brake signal lamps (205) are switched on. At 702, the brakes are mechanically actuated in the vehicle. The distance between 701 and 702 is minuscule and short, therefore, the brake is mechanically actuated immediately after the one or more brake signal lamps (205) are switched on by the brake switch system (201). This is done for adequate indication of braking and warning the other vehicle users on the road. At 703, the braking signal is sent to the idle start stop controller (202). This idle start stop controller (202) takes the braking signal and throttle signal (106) as inputs for consideration of switching off of engine in the vehicle.

It will be further appreciated that the variants of the above disclosed system elements, modules, and other features and functions, or alternatives thereof, may be combined to create other different systems or applications.
[00055] The present claimed invention solves the technical problem of using an exemplary brake switch system, which can be a secondary circuit breaker to control idle start stop system of a vehicle, without affecting the current arrangement of the brake signal lamps.
[00056] The present invention aims to increase the performance of a vehicle by ensuring smooth restarting of the engine of the vehicle, and efficiently saving energy by turning-off the engine when the vehicle is in an idle condition. Additionally, the emissions of a vehicle are also decreased due to the idle start stop system switching off the engine when in an idle condition, therefore, making a positive impact on the environment. The idle start stop system also improves the pick-up of the vehicle.
[00057] The present invention aims to increase the durability and handling of a vehicle due to better response of the idle start stop system.
