A battery electric vehicle includes an electric motor as a driving source. The battery electric vehicle includes: a driving operation member that is used to drive the battery electric vehicle; a pseudo shifting operation member imitating an operation member that is used to perform a shifting operation of a manual transmission internal combustion engine vehicle; a processor that controls the battery electric vehicle according to operation of the driving operation member; and an in-vehicle battery that is charged with electrical energy generated when regenerative braking of the battery electric vehicle is applied. The processor executes, according to selection by a driver, a control mode in which operation of the pseudo shifting operation member is associated with torque of the electric motor.

Battery electric vehicle

A battery electric vehicle includes: a driving operation member configured to be used to drive the battery electric vehicle; and a pseudo shifting operation member that imitates an operation member configured to be used to perform a shifting operation of a manual transmission internal combustion engine vehicle. A controller that controls the battery electric vehicle is configured to execute, according to selection by a driver, a control mode in which an operation of the pseudo shifting operation member is associated with torque of the electric motor. The controller is further configured to impose, when in the control mode, a restriction on an operation the battery electric vehicle performs in response to the operation of the pseudo shifting operation member, the restriction being able to be removed or eased.

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.

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 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

A driving apparatus includes: a first power source; a fluid transmission device; a first output shaft for receiving a power transmitted from the fluid transmission device through a first power transmission path and outputting the power to drive wheels of a vehicle; a rotary electric machine connected to the first output shaft and/or the drive wheels, through a second power transmission path; and a control device. When the vehicle is stopped or running at an extremely low speed, with a rotary-electric-machine driving mode being established, the control device is configured, upon determination that a drive request amount is larger than a threshold amount value, to place a direct clutch of the fluid transmission device into an engaged state and to place the first power transmission path into a power transmittable state so as to cause the power of the first power source to be outputted to the first output shaft.

Driving apparatus for vehicle

It is determined whether fuel efficiency of a vehicle is improved by operating a first rotating machine to generate electricity to such an extent that an electrical path amount becomes a desired electrical path amount for controlling an operating point of an engine to a desired operating point and driving and operating a second rotating machine as a second power source, the electrical path amount being a magnitude of electric power in an electrical path through which the electric power is transferred between the first rotating machine and the second rotating machine. When the electronic control device determines that the fuel efficiency of the vehicle is improved, the first rotating machine is operated to generate electricity to such an extent that the electrical path amount becomes the desired electrical path amount and the second rotating machine is driven and operated as the second power source.

Vehicle drive device and control method therefor

A vehicle driving apparatus includes: an engine; first and second rotary electric machines; a fluid transmission device including an input-side rotary element to which the engine and the first rotary electric machine are connected; and a control device configured to control an operation point of the engine by adjusting an electrical path amount in an electrical path between the first and second rotary electric machines. When a certain running mode is established, the control device is configured to correct the electrical path amount to an increased electrical path amount while maintaining an power of the engine requested by an operation of a vehicle driver, and to drive the second rotary electric machine, while controlling an output torque of the first rotary electric machine such that the electrical path amount transferred from the first rotary electric machine to the second rotary electric machine becomes the increased electrical path amount.

In an internal combustion engine having a cylinder in which an air-fuel mixture of gaseous fuel and intake air is combusted, an intake passage connected to the cylinder, and a supercharger for supercharging the intake air, in a case where backfire is generated in a set period before supercharging is performed by the supercharger, supercharging is performed at a smaller supercharging pressure than in a case where backfire is not generated in the set period.

Control device of internal combustion engine

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.
