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.

Electric vehicle having synthesized internal combustion engine sound

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.

Electric vehicle

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.

Electric vehicle having a simulated manual transmission

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.

Drive force control system for vehicle

An electric vehicle is configured to be able to perform running by an MT mode that controls an electric motor with a torque characteristic like an MT vehicle having a manual transmission and an internal combustion engine, and running by an EV mode that controls the electric motor with a normal torque characteristic. The electric vehicle includes a mode changeover switch for switching to the running by the MT mode.

A shifting mechanism, in which a movable member integrated with an engagement pin will not be rotated by a friction acting between a cam groove and the engagement pin, includes: a shift drum that on which a cam groove is formed; a cam sleeve having an engagement pin inserted into the cam groove; a fork shaft reciprocated between predetermined positions by rotating the shift drum; a support stem extending parallel to a center axis of the cam sleeve; and a projection formed integrally with the cam sleeve to come into contact with the support stem when the cam sleeve is rotated.

Shifting mechanism

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.

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. The controller of the electric vehicle controls the electric motor in the MT mode such that responsiveness of the motor torque with respect to a change in the operation amount of the accelerator pedal is lower than in the EV mode.

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 shift reaction force generator that generates a shift reaction force in response to the operation of the pseudo-shifter using by the operating of the reaction force actuator. The controller is configured to store the shift reaction force characteristic simulating the characteristic of the shift reaction force according to the operation of the shifter. Then, the controller is configured to control the shift reaction force output by the shift reaction force generator according to the operation of the pseudo-shifter using the stored shift reaction force characteristic.

A control system for a hybrid vehicle configured to shift an operating mode from a single-motor mode to a hybrid-low mode without causing a temporal drop in a drive force. A controller is configured to predict an execution of a mode change from the single-motor mode to the first hybrid mode, and to execute the mode change from the single-motor mode to the hybrid-low mode via a hybrid-high mode, if the execution of the mode change from the single-motor mode to the hybrid-low mode is predicted.
