Abstract: 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.

Abstract: A battery electric vehicle according to an embodiment of the present disclosure includes a pseudo gear shift operation member that imitates an operation member used in gear shift operation of a manual transmission internal combustion engine vehicle in addition to a driving operation member used in driving thereof. A control apparatus that controls battery electric vehicle is configured to control the operation of the battery electric vehicle with respect to operation of the driving operation member in accordance with an operation state of the pseudo gear shift operation member. The control apparatus executes deceleration control that autonomously decelerates an own vehicle when the own vehicle enters a curved road. The control apparatus encourages a driver to operate the pseudo gear shift operation member in a manner similar to that when a gear ratio of the manual transmission internal combustion engine vehicle is increased when the deceleration control is executed.

Abstract: The electric vehicle of the present disclosure includes an accelerator pedal, a paddle type shifter, and a motor controller. The paddle type shifter is pre-registered with upshift operation, downshift operation, and mode switching operation. The motor controller switches a control mode of the electric motor between a manual mode and an automatic mode in response to the mode switching operation on the paddle type shifter. When the control mode is the automatic mode, the motor controller changes an output of the electric motor in accordance with the operation of the accelerator pedal. On the other hand, when the control mode is the manual mode, the motor controller changes an output characteristic of the electric motor with respect to the operation of the accelerator pedal in accordance with the upshift operation and the downshift operation of the paddle type shifter.

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.
