A launch control system and method for an electric vehicle, which are capable of satisfying a driver's demand for a high-performance vehicle by realizing the high performance of the electric vehicle. The system and method maximize acceleration at an initial stage of launching the electric vehicle from a standstill, thereby shortening the time to reach the maximum acceleration when launching the electric vehicle from the standstill.

A method and system for controlling an electric mobility are provided. The method and system may determine whether a brake is operated in a stationary state in which the electric mobility is stopped; convert the state of the electric mobility from the stationary state into a brake operation state if it is determined that the brake is operated in the stationary state; determine whether the brake is released in the brake operation state; and convert the state of the electric mobility from the brake operation state into a standby state in which the mobility can be started if it is determined that the brake is released in the brake operation state.

The present disclosure relates to a battery assisting apparatus and method for a fuel cell vehicle. An exemplary embodiment of the present disclosure provides a battery assisting apparatus for a fuel cell vehicle, including: a controller configured to determine an increase or decrease of driver's determination to accelerate based on a change rate of motor torque and a change rate of accelerator opening when a battery assistance mode is entered, and to release the battery assistance mode when the driver's determination to accelerate is decreased; and a storage configured to store data and algorithms driven by the controller.

A method for controlling torque generated by at least one traction motor of a vehicle before a vehicle launch includes: determining that torque demand increases while simultaneously at least one brake of the vehicle is in an applied state; in dependence on the determination, limiting torque generation by the traction motor in response to torque demand; and removing the limit in dependence on release of the at least one brake.

In a non-started-up state of a vehicle, a first power conversion circuit operates to convert a voltage of a second level from a second power supply into a voltage of a third level, a first and a second switches are each controlled to a connection state, the voltage of the second level from the second power supply is supplied to a first load and the first power conversion circuit, the voltage of the second level from the second power supply is supplied to a second load via the first switch, the voltage of the third level from the first power conversion circuit is supplied to the first load, and the voltage of the third level from the first power conversion circuit is supplied to the second load via the second switch.

A jackrabbit start suppression device that suppresses a jackrabbit start of a vehicle is provided. The vehicle includes a drive motor, an accelerator pedal, a simulated clutch pedal, and a simulated shift lever. The jackrabbit start suppression device includes at least one processor and at least one memory. The at least one processor sets a travel mode at next startup of the vehicle to an MT mode, regardless of whether last startup of the vehicle was stopped while the vehicle being in the MT mode, in which a gearshift operation and a clutch operation are enabled, or in an AT mode, in which the gearshift and clutch operations are disabled. The at least one processor prohibits startup of the vehicle when the driver performs a startup operation of the vehicle while a depression of the simulated clutch pedal is less than or equal to a prescribed value.

An electric vehicle includes an electric traction motor configured to selectively provide torque to vehicle wheels, a shifter configured to shift the electric vehicle, and a motor control system for electric traction motor quadrant protection in steady and transient shifter positions. The motor control system is in signal communication with the electric traction motor and the shifter, and includes a controller having one or more processors. The controller is programmed to monitor the shifter, detect a garage shift, and upon detecting the garage shift, filter the electric traction motor torque to zero to smoothly transition the electric traction motor during the garage shift and allow the garage shift to complete before an electric motor quadrant protection is initiated.

A control system for an electric vehicle configured to simulate an engine stall which might occur in conventional vehicles while preventing the simulation of the engine stall in an unfavorable situation. A controller of the control system is configured to: execute an engine stall control to simulate a behavior of the conventional vehicle in a situation where an engine stall occurs by stopping a motor, when a virtual engine speed calculated by a virtual engine speed calculator falls below a predetermined speed; and execute a hold assist control to apply a brake torque to the wheel by the brake device upon execution of the engine stall control.
