The present disclosure generally relates to a vehicle. Particularly but not exclusively, disclosure relates to auto start-stop system of the vehicle. Further, embodiments of the present disclosure disclose method for auto start and auto stop of an engine of the vehicle.

BACKGROUND OF DISCLOSURE

One or more conventional strategies for auto start-stop in a vehicle involve a driver to switch gear into neutral. In one embodiment, for activating auto stop feature, the vehicle is brought to a complete rest and the driver switches the gear into neutral and also by checking one or more parameters such as but not limited to state of charge of battery, conditions of engine temperature etc. Further, in one embodiment, for activating auto start feature the driver will depress the clutch and press the brake of the vehicle.

The above mentioned strategies may be satisfactory, but not intuitive for the driver nor easy to use. The driver in one or more countries, especially those who drive in cities, do not slide gear of the vehicle into neutral every time the vehicle is stopped at a traffic signal. Also driver would not prefer to follow confusing and complex methodology to start the engine every time after it gets switched off. City driving conditions in one or more countries often offer maximum possibility to save on fuel economy and provide annoyance to the driver by complicated operation of the conventional strategies of auto start-stop system. This discourages the driver rather than from taking advantage of the auto start-stop system. Consequently, the driver tends to switch off the auto start-stop system and would prefer manual stopping and starting of the engine. Thereby, the engine will no longer switch off automatically as per the control strategy requirements. Further, this leads in increase of emissions during idling and reduction of fuel due to the idling.

In light of foregoing discussion, it is observed that there exists a need for a more intuitive auto start-stop system for the vehicle to overcome the limitations stated above and also to maintain highest levels of safety and prevent accidental startups of the vehicle.

The following description is, therefore, not to be taken in a limiting sense.

FIG. 1 illustrates a flow diagram for auto-stop strategy in a vehicle, in accordance with the present disclosure.

The flow diagram 100 illustrates a method to auto stop an engine of a vehicle. For an auto stopping of the engine in a vehicle when the engine is ON, initially the system checks for the vehicle speed and state of charge of a battery in the vehicle. When the vehicle speed is zero and the state of charge of the battery is greater than a predefined value (X1) at step 101, the system checks for previous maximum speed of the vehicle in step 103. Otherwise, the system will not switch off the engine at step 102. The previous maximum speed of the vehicle is maximum speed of the vehicle from which the speed has decreased to zero. When the previous maximum speed of the vehicle is greater than a predefined value (V), then the system waits for a first predefined time, for example t1 seconds, at step 104. Otherwise, the system waits for a second predefined time, for example t2 seconds, at step 105. In an exemplary embodiment the value of t1 is 5 seconds and value of t2 is 10 seconds. After waiting for one of first predefined time and second predefined time, the system prepares to switch off the engine at step 106.Before switching off the engine, the system checks the engine speed and the clutch position. When the engine speed is greater than zero and when the clutch is pressed at step 107, the system understands the vehicle is in neutral and assigns a neutral position flag with ‘1’ at step 108. Otherwise, the system understands the vehicle is not in neutral and assigns the neutral position flag with ‘0’ at step 109. The neutral position flag is a variable parameter which is used to detect the neutral position in the gear leaver eliminating the neutral gear position sensor. Also, the neutral position helps in determining on how the vehicle has to auto start (i.e. at what conditions will the auto start work) when auto starting the vehicle. Upon assigning one of ‘1’ or ‘0’ to the neutral position, the system switches off the engine of the vehicle at step 110.

FIG. 2 illustrates a flow diagram for auto-start strategy in a vehicle, in accordance with the present disclosure.

For auto starting of an engine in a vehicle which is auto stopped at step 201, initially the system checks for state of charge of battery in the vehicle. When the state of charge of the battery is lesser than a predefined value (X2) at step 202, then a predefined amount of torque is demanded by a controller and provided to an integrated starter generator at step 203. The amount of torque demanded by the controller in one embodiment depends upon the engine of the vehicle and will be lesser than or equal amount of torque required to just start the engine. When current drawn by the integrated starter generator is lesser than a predefined value (Y) at step 204, then the system will switch on the engine at step 209. The switching on of the engine will lead in charging of the battery. Otherwise, the system will alert driver to switch on the engine at step 207. The alerting may be through infotainment system or a beep alarm. In one embodiment, the driver switches on the engine manually. In another embodiment, the driver switches on the engine as per the mechanisms of auto start in conventional vehicles. In one embodiment the current drawn by the integrated starter generator less than the predefined value (Y) would mean that the vehicle gear leaver is in neutral condition. If the vehicle gear is not in neutral condition then the current drawn would be greater than the predefined value (Y).

Further, when the state of charge of the battery is greater than a predefined value (X2), then the system checks on condition by which the vehicle was stopped by checking the neutral position at step 206. The system also detects whether the vehicle is in neutral or not by checking the neutral position flag at step 206. When the neutral position flag is ‘1’ i.e., if clutch is being pressed when the vehicle was auto stopped, then by pressing the accelerator pedal for a second predefined threshold (Z2) at step, the system will switch on the engine of the vehicle at step 209. When the neutral position flag is ‘0’ i.e., if the clutch was not pressed when the vehicle was auto stopped, then by pressing the clutch for more than a first predefined threshold (Z1) at step 207, the system will switch on the engine at step 209. In one embodiment, Z1 is 80% of full press condition of clutch and Z2 is 1% of full press condition of the accelerator pedal.

FIG. 3 illustrates an exemplary block diagram representation of system of a vehicle for auto stop-start strategy, in accordance with the present disclosure.

The system (300) comprises of a brake switch (301), a clutch switch (302), an accelerator pedal switch (303), an engine control unit (304), a battery sensor (305), an engine management system (306) and an integrated starter generator (307). The brake switch (301), the clutch switch (302) and the accelerator pedal switch (303) are few of the vehicle controls used for controlling the vehicle by the driver. The engine control unit (304) consists of a hardware processor and a memory storing instructions executable by the hardware processor which is configured to perform functions of the auto stop-start strategy in accordance with the present disclosure as illustrated with respect to FIG. 1 and FIG.2. The functions performed by the engine control unit (304) involves detecting speed of the vehicle is zero and determining state of charge of a battery of the vehicle is greater than a predefined threshold value. Also, detects previous maximum speed of vehicle when the vehicle speed reaches zero and checks if clutch not pressed. Further, the functions involve waiting for a first predefined time when the previous maximum speed is greater than a first predefined value and waiting for a second predefined time when the previous maximum speed in lesser than the threshold value. By this, that is the clutch not pressed and the engine is still rotating , the engine control unit understands that the vehicle is in neutral condition and thereby switches off the engine after waiting for one of the first predefined time and the second predefined time. Thus, the engine control unit is able to determine the neutral condition of a gear leaver without presence of a neutral gear sensor.

The engine control unit also performs the functions of determining neutral condition of the gear leaver of the vehicle during auto start of the vehicle by providing a predefined amount of torque by a controller, to an integrated starter generator when the state of charge of the battery is lesser than a third predefined value. Further performs at least one of switching on the engine of the vehicle when the current drawn by the integrated starter generator is lesser than a predefined value and alerting a user of the vehicle to switch on the engine. When the state of charge of the battery is greater than the third predefined value, the engine control unit checks the condition by which the vehicle has been stopped and starts the vehicle as illustrated in FIG 2.

The battery sensor (305) determines state of charge of the battery in the system. The auto stop and the auto start in the system in one embodiment depend upon the state of charge of the battery. The engine management system (306) is configured to manage the system. The integrated starter generator (307) in accordance with the present disclosure is used for determining neutral condition of gear leaver of the vehicle. A controller is configured in the system to demand a predefined amount of torque and is supplied to the integrated starter generator. The torque which is demanded is enough to trigger start the engine of the vehicle and varies with respect to the engine. The integrated starter generator (307) draws current when the torque is supplied. Further, depending upon the current drawn, the system determines the neutral condition. When the amount of current drawn by the integrated starter generator is lesser than a predefined value, then the system determines that the vehicle is in neutral. When the amount of current drawn by the integrated starter generator (307) is greater than the predefined value, then the system determines that the vehicle is not in neutral. In one embodiment, the auto start of the engine of the vehicle is activated in when the system is in neutral.

Advantages:
The present disclosure is to provide an auto stop system for a vehicle which can switch off the engine by considering parameters such as but not limited to state of charge of battery, previous maximum vehicle speed and so on.

The present disclosure is to provide an auto start system for a vehicle which can switch on the vehicle by considering state of charge of battery and also discloses a new method for determining the neutral condition of the gear leaver.

Overall, the present disclosure provides an auto stop-start system which eliminates the implementation of the neutral gear sensor and thereby provides an intuitive stop-start strategy.
