  • Patent number: 12654568
    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.

  • Patent number: 12583332
    Abstract: The electric vehicle according to the present disclosure calculates motor torque using an MT vehicle model simulating an MT vehicle having a manual transmission and an internal combustion engine. In the first operation mode, an operation amount of a pseudo-clutch pedal and a shift position of a pseudo-gearshift are input to the MT vehicle model to reflect operation of the pseudo-clutch pedal and operation of the pseudo-gearshift in electric motor control. In the second operation mode where the operation of the pseudo-clutch pedal is not needed, an operation amount of a clutch pedal calculated by a driver model is input to the MT vehicle model instead of the operation amount of the pseudo-clutch pedal.

  • Patent number: 12263831
    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.
