Abstract

A battery electric vehicle includes: a driving operation member; 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; and a controller configured to control the battery electric vehicle according to an operation of the driving operation member. A plurality of control modes includes a manual mode and an automatic mode. The controller includes a memory. The controller determines, upon starting of the battery electric vehicle, whether a new driver who has entered the battery electric vehicle is included in one or more candidate drivers. When the new driver is included in the one or more candidate drivers, the controller starts the control mode linked with the new driver.

Claims (38)

1 . A battery electric vehicle including an electric motor as a driving source and having a plurality of control modes that is selectable by a driver, the battery electric vehicle comprising:

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; and a controller configured to control the battery electric vehicle according to an operation of the driving operation member, wherein

the control modes include a manual mode in which an operation of the pseudo shifting operation member is associated with torque of the electric motor, and an automatic mode in which the operation of the pseudo shifting operation member is not associated with the torque of the electric motor,

the controller includes a memory configured to store linking information in which one or more candidate drivers are linked with the control mode and registered, the controller is configured to determine, upon starting of the battery electric vehicle, whether a new driver who has entered the battery electric vehicle is included in the one or more candidate drivers,

the controller is configured to, when the new driver is included in the one or more candidate drivers, start the control mode linked with the new driver,

the control mode linked with the new driver is the control mode that was selected when the new driver last drove the battery electric vehicle, and

the control mode that was selected when the new driver last drove the battery electric vehicle is the control mode that had been set between when the new driver last finished driving the battery electric vehicle and when the new driver turned off power of the battery electric vehicle, or the control mode that was set when the new driver last entered the battery electric vehicle and turned on accessory power of the battery electric vehicle.

2 . The battery electric vehicle according to claim 1 , wherein:

when in the manual mode, a characteristic of the manual transmission internal combustion engine vehicle that is to be simulated by the battery electric vehicle is determined according to a setting related to a detailed mode that is selectable by the driver;

the linking information includes information about the setting related to the detailed mode linked with the one or more candidate drivers; and

the controller is configured to, when the new driver has been linked with the manual mode upon starting of the battery electric vehicle, set the detailed mode to the setting linked with the new driver.

3 . The battery electric vehicle according to claim 2 , wherein the setting related to the detailed mode is either a selection result from options or a combination of selection results from the options, the options being options related to any one or more of the following: an engine characteristic, an engine sound, a drive mode, and a suspension characteristic.

4 . The battery electric vehicle according to claim 2 , wherein the setting related to the detailed mode is either a selection result from options or a combination of selection results from the options, the options being options related to any one or more of the following: a shift mode, an engine characteristic, an engine sound, a drive mode, and a suspension characteristic.

5 . The battery electric vehicle according to claim 1 , wherein:

the driving operation member includes an accelerator pedal; and

the pseudo shifting operation member includes

a pseudo H-shifter imitating an H-shifter of a manual transmission, and

a pseudo clutch operation device imitating a clutch operation device.

6 . The battery electric vehicle according to claim 5 , wherein the controller is configured to, when in the control mode, change the torque of the electric motor according to a shift position selected by the pseudo H-shifter, an amount of operation of the pseudo clutch operation device, and an amount of operation of the accelerator pedal.

7 . The battery electric vehicle according to claim 1 , wherein:

the driving operation member includes an accelerator pedal; and

the pseudo shifting operation member includes a pseudo sequential shifter imitating a sequential shifter of a manual transmission.

8 . The battery electric vehicle according to claim 7 , wherein the controller is configured to, when in the control mode, change the torque of the electric motor according to a shift position selected by the pseudo sequential shifter and an amount of operation of the accelerator pedal.

9 . The battery electric vehicle according to claim 1 , wherein:

the driving operation member includes an accelerator pedal; and

the pseudo shifting operation member includes a pseudo H-shifter imitating an H-shifter of a manual transmission.

10 . The battery electric vehicle according to claim 9 , wherein the controller is configured to, when in the control mode, change the torque of the electric motor according to a shift position selected by the pseudo H-shifter and an amount of operation of the accelerator pedal.

11 . The battery electric vehicle according to claim 6 , wherein:

the driving operation member includes an accelerator pedal;

the pseudo shifting operation member includes

a pseudo H-shifter imitating an H-shifter of a manual transmission,

a pseudo clutch operation device imitating a clutch operation device, and

a pseudo sequential shifter imitating a sequential shifter of the manual transmission; and

the detailed mode includes

a mode in which the torque of the electric motor is changed according to a shift position selected by the pseudo H-shifter, an amount of operation of the pseudo clutch operation device, and an amount of operation of the accelerator pedal,

a mode in which the torque of the electric motor is changed according to a shift position selected by the pseudo sequential shifter and the amount of operation of the accelerator pedal, and

a mode in which the torque of the electric motor is changed according to the shift position selected by the pseudo H-shifter and the amount of operation of the accelerator pedal.
