Abstract: A driving force control system for a vehicle that eliminates backlash in torque transmission paths when decelerating or stopping the vehicle. In the vehicle, a differential unit reverses a torque delivered from a motor to a second output shaft. A controller generates a drive torque by an engine and a control torque by the motor when stopping or decelerating the vehicle. Consequently, a difference between torque delivered from the engine to a first output shaft and torque delivered from the motor to the first output shaft is increased to a first predetermined torque or greater, and torque delivered from the motor to the second output shaft is increased to a second predetermined torque or greater.

Abstract: An electric vehicle includes a shift lever and a clutch pedal for simulating manual gear changes of a traditional vehicle equipped with an internal combustion engine and manual transmission, and includes a controller for controlling the operation of the electric vehicle. The driver operates the shift lever in a similar fashion to that of a traditional manual transmission shift lever, however the associated gear positions do not correspond to physical gears in a transmission but rather virtual gear stage modes that correspond to mapped torque characteristics with respect to the rotational speed of the electric motor. The clutch pedal is operated by the driver when the shift lever is operated. The controller calculates the virtual engine speed of the virtual engine based on the virtual gear stage mode selected by the shift lever and the operation amount of the clutch pedal, and displays the virtual engine speed on a display.

Abstract: A control system for a vehicle configured to stabilize a behavior of the vehicle by controlling a split ratio of torque distributed to front wheels and rear wheels. In the vehicle, a split ratio of the torque distributed to the front wheels and to the rear wheels through a transfer is changed by a torque of the motor.
The control system is configured to execute a drive force distribution control to control the torque of the motor to adjust the split ratio to a target ratio, and to execute a turning behavior stabilizing control instead of the drive force distribution control to temporarily increase the torque of the motor when the vehicle is understeering or oversteering.

Abstract: The controller of the electric vehicle is configured to control the torque of the electric motor using the MT vehicle model based on the operation amount of the accelerator pedal, the operation amount of the pseudo-clutch pedal, and the shift position of the pseudo-shifter. The electric vehicle also includes a pedal reaction force generator that generates a pedal reaction force in response to the operation of the pseudo-clutch pedal using by the operating of the reaction force actuator. The controller is configured to store the pedal reaction force characteristic simulating the characteristic of the pedal reaction force according to the operation of the clutch pedal. Then, the controller is configured to control the pedal reaction force output by the pedal reaction force generator in response to the operation of the pseudo-clutch pedal using the stored pedal reaction force characteristic.

Abstract: A drive force control system for a vehicle configured to accurately imitate a change in a drive force in a model vehicle. A drive torque simulator computes a virtual drive torque supposed to be delivered to drive wheels of the model vehicle in response to a manual operation to manipulate the vehicle, based on torque changing factors of a powertrain of the model vehicle. An actual torque calculator computes a target torque of a motor that is practically delivered to the drive wheels in the vehicle based on the virtual drive torque computed by the drive torque simulator, taking account of torque changing factors of the powertrain of the vehicle.

Abstract: When temperature of a second power source of a vehicle becomes higher than a threshold value during a first mode in which three rotating elements of a differential gear can make differential movement and when four-wheel drive is needed, switching is performed to a second mode in which the three rotating elements are unified, and when four-wheel drive is not needed even when the temperature of the second power source becomes higher than the threshold value during the first mode, output of the second power source is restricted, while the first mode is maintained.
