  • Publication number: 20220041070
    Abstract: The electrical vehicle includes a shift lever and a clutch pedal for pseudo-realizing the manual gear change operation of the MT vehicle, and a controller for controlling the operation of the electric vehicle. The shift lever is operated by the driver to select an arbitrary virtual gear stage mode from among a plurality of virtual gear stage modes in which torque characteristics with respect to the rotational speed of the electric motor are stepwise different. 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 the display.

  • Publication number: 20220041067
    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. Further, the controller is configured to execute the stall production process for changing the engine output torque used for calculation of the driving wheel torque to zero when the calculated virtual engine speed using the MT vehicle model becomes lower than the prescribed stall engine speed.

  • Publication number: 20220041062
    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.

  • Publication number: 20220041064
    Abstract: The electric vehicle according to the present disclosure is configured to be able to select a traveling mode between an MT mode in which an electric motor is controlled with torque characteristics like an MT vehicle having a manual transmission and an internal combustion engine, and an EV mode in which the electric motor is controlled with normal torque characteristics. When the selection of the travelling mode is changed by a driver, the controller of the electric vehicle determines whether a control mode can be switched, based on a condition in which the electric vehicle is placed, and switches the control mode in accordance with the determination result.

  • Publication number: 20220041157
    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.

  • Patent number: 11065974
    Abstract: A vehicle control system for an autonomous vehicle configured to charge a battery by an external power source during propulsion while preventing a deterioration of the battery. A controller detects a charging zone where the electric storage device can be charged by the external power source, and restricts at least any one of a charging of the electric storage device and a discharging of electricity from the electric storage device so as to limit a load factor of the electric storage device to be smaller than a predetermined limit value when the vehicle passes through the charging zone.
