Description:FIELD OF THE INVENTION
[001] The present invention relates to a vehicle and a method of operating the vehicle.

BACKGROUND OF THE INVENTION
[002] In conventional vehicle layouts employing an ISG controller and an ISG machine configuration connected to the prime mover, the ISG combination functions such that, the ISG machine acts as a motor during vehicle starting condition, whereby the ISG machine gets a power DC power input from the battery (12V lead acid battery) of the vehicle which then leads to rotation of ISG machine, and the ISG machine initiates crankshaft rotation during vehicle starting condition. Further, the ISG machine acts as a generator during vehicle running condition, whereby the rotation of the crankshaft leads to rotation of the ISG machine, which then generates electricity to power the vehicular components such as instrument cluster, lighting units, etc.
[003] In other conventional layouts a starter motor is employed for initiating vehicle starting in conjunction with a rectifier regulation unit and magneto for supporting ancillary vehicle electrical loads of vehicle components.
[004] In the conventional vehicle layout and the vehicle being in running condition, the rider upon providing a requisite throttle input and acceleration requirement the ISG machine fails to support the vehicle performance. Since during vehicle running condition the prime mover/ crankshaft’s rotation is supplied as input to support two major functions like wheel rotation to support vehicle propulsion, and ISG machine rotation operating as generator to support the supply of electric power (ac to dc conversion) to one or more vehicle components. Therefore, any acceleration/ throttling input leads to a lag in acceleration since the prime mover is already sustaining two parallel operations.
[005] In one kind of existing electric assist system includes a crankshaft that is rotated by the human power of a rider applied to a pedal; and an electric motor that generates auxiliary force of human power. The electric assist system further includes a control device that controls a magnitude of the auxiliary force generated by the electric motor, and an acceleration sensor whose output corresponds to the acceleration in the direction of travel of the electric auxiliary vehicle. The control device changes the magnitude of the assisting force generated by the electric motor according to a change in acceleration that is linked to the rider's pedaling action.
[006] This kind of electric assist system is provided to the prime mover. However, the electric assist system doesn’t provide a massive power as expended in assist. For instance, in an event when assist is used, roughly 40 amperes of current flows from the battery via the ISG machine to the prime mover.
[007] Further, the users of vehicles are more concerned about the acceleration and mileage. In the internal combustion engine vehicle, battery is used to provide more power to engine for enhancing the acceleration and mileage. But when multiple time power is taken from battery, battery life will be degraded.
[008] In view of the above, there is a need for a vehicle and method of operating a vehicle to overcome one or more limitations stated above.

[039] Figure 2 is the flow diagram of a method 200 for operating the vehicle, in accordance with the embodiment of the present subject matter.
[040] At a step 202, the control unit 108 is adapted to receive a first input from an electrical device 104. The first input being indicative of a state of operation of the electrical device 104 based on the one or more pre-defined conditions. The state of operation includes a generator state as well as a motor state. During operation in the generator state, the kinetic energy from the prime mover 102 is converted into potential energy to be stored to be stored in the electrical storage device. Further during operation in motor state, the potential energy from the energy storage device 110 is converted into kinetic energy by the electrical device 104. At this scenario, the control unit 108 moves to a step 204.
[041] At the step 204, the control unit 108 is adapted to receive a second input from one or more sensing devices 106 of the vehicle. The second input is indicative of one or more vehicle operating conditions. The control unit 108 is adapted to receive vehicle operating conditions at step 204 including, but not limited to, the rotational speed of the engine of the vehicle, temperature of the engine, State of Charge of the energy storage device 110, percentage of throttle activated by a rider of the vehicle, health of the control unit 108, and a percentage of change of throttle opening a time taken for the change in the throttle opening and the like.
[042] Further, when the control unit 108 determines that the rotational speed of the engine of a vehicle is above a pre-set threshold, the vehicle parameters such as engine rotation speed, SoC of the energy storage device 110, the engine temperature, the health of the one or more sensing devices 106, the health of the control unit 108, a percentage of change in throttle opening and a time taken for the change in the throttle opening are within a pre-set range, the control unit 108 at a step 206, generates a signal based on the first input and the second input to operate the electrical device 104 in the motor state.
[043] During operation the motor state comprises a first state and a second state. The first state includes the electrical device 104 configured to receive a power input from the energy storage device 110 powering one or more vehicle components. The second state includes the electrical device 104 configured to receive a pre-set power from the energy storage device 110 powering the prime mover 102 for a pre-set time duration, based on the first input and the second input.
[044] Figure 3 is a flow diagram of a method 300 for operating the vehicle in accordance with an embodiment of the present invention. After the start at a step 302, at a step 304, the control unit 108 receives a first input from the electrical device 104, the first input is indicative of a state of operation of the electrical device 104 based on the one or more pre-defined conditions. In an embodiment the one or more pre-defined condition for vehicle running condition may include speed of rotation of the engine being greater than 1600 rpm.
[045] At a step 306, the control unit 108 receives a second input from the one or more sensing devices 106 of the vehicle, the second input being indicative of one or more vehicle operating conditions including the SoC of the energy storage device 110, the engine temperature, the health of the one or more sensing devices 106, the health of the control unit 108.
[046] At a step 308, the throttle position sensor is checked by the control unit 108 for throttle opening input. Further at a step 310, if the change in throttle position determined by the control unit 108 is greater than fifty percent (50%), the control unit 108 is configured to send a signal to the energy storage device 110 to supply a current from the energy storage device 110 to the electrical device 104 that is utilized for vehicle propulsion.
[047] Furthermore, at a step 310, if the change in throttle position determined by the control unit 108 is not greater than fifty percent (50%), the control unit 108 keeps on checking the input from the throttle position sensor. Upon receiving the change in throttle position determined by the control unit 108 and being greater than fifty percent (50%), the control unit 108 moves to a step 312.
[048] At a step 312, the control unit 108 is sends a signal to the energy storage unit 110 to supply a current to the electrical device 104 from the energy storage unit 110. In an embodiment of the present invention the current supplied to the electrical device 104 from the energy storage unit 110 is 4 amperes. The current is utilized by the electrical device 104 for the rotation of the prime mover 102, thereby enabling vehicle propulsion.
[049] Advantageously, the present invention provides improved overall vehicle performance. Due to the power being supplied to the prime mover 102 is of a much lesser value of say 4 amperes against the conventional assist as disclosed in the background of the present invention, which is 40 amperes, the time for enabling acceleration is reduced and further the subsequent throttling can be activated in a shorter time span. The current supplied for the rotation of the prime mover 102 enables mileage improvement for the vehicle as lesser amount of fuel is needed for acceleration of the vehicle. Moreover, the power pick-up and acceleration are improved along with reduced exhaust emissions. Additionally, the life cycle of the energy storage device 110 is not deteriorated due to repeated discharging and charging as disclosed in the existing prior arts.
[050] Furthermore, one or more computer-readable storage media may be utilized in implementing embodiments consistent with the present disclosure. A computer-readable storage medium refers to any type of physical memory on which information or data readable by a processor may be stored. Thus, a computer-readable storage medium may store instructions for execution by one or more processors, including instructions for causing the processor(s) to perform steps or stages consistent with the embodiments described herein.
