Abstract

A battery electric vehicle includes: an electric motor configured to serve as a driving source for the battery electric vehicle; a driving operation member configured to be used to drive the battery electric vehicle; 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 transmission mounted between the electric motor and a drive wheel and configured to allow a driver to manually switch between a gear ratio for normal use and a low-speed gear ratio; and a control device configured to control a motion of the battery electric vehicle in response to an operation of the driving operation member according to an operation state of the pseudo shifting operation member and a gear ratio selected by the transmission.

Claims (22)

1 . A battery electric vehicle comprising:

an electric motor configured to serve as a driving source for the battery electric vehicle;

a driving operation member configured to be used to drive the battery electric vehicle;

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 transmission mechanically coupled between the electric motor and a drive wheel and configured to allow a driver to manually switch between a gear ratio for normal use and a low-speed gear ratio; and

a control device configured to control a motion of the battery electric vehicle in response to an operation of the driving operation member according to an operation state of the pseudo shifting operation member and a gear ratio selected by the transmission.

2 . The battery electric vehicle according to claim 1 , wherein the transmission is a transfer case configured to select from four-wheel drive low gear, four-wheel drive high gear, and two-wheel drive high gear.

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

the driving operation member includes an accelerator pedal;

the pseudo shifting operation member includes a pseudo shifter imitating a shifter of a manual transmission; and

the control device is configured to change torque of the electric motor according to an amount of operation of the accelerator pedal, a shift position selected by operating the pseudo shifter, and the gear ratio selected by the transmission.

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

the driving operation member includes an accelerator pedal;

the pseudo shifting operation member includes

a pseudo shifter imitating a shifter of a manual transmission, and

a pseudo clutch operation device imitating a clutch operation device; and

the control device is configured to change torque of the electric motor according to an amount of operation of the accelerator pedal, a shift position selected by operating the pseudo shifter, an amount of operation of the pseudo clutch operation device, and the gear ratio selected by the transmission.

5 . The battery electric vehicle according to claim 3 , wherein:

the pseudo shifter is configured to select from a plurality of shift positions;

the shift positions are assigned different virtual gear ratios; and

the virtual gear ratios are set in such a manner that none of combinations of the virtual gear ratio and the gear ratio selected by the transmission have a same overall gear ratio, the overall gear ratio being obtained by multiplying the virtual gear ratio by the gear ratio of the transmission.

6 . The battery electric vehicle according to claim 4 , further comprising a sound generator configured to artificially generate a sound in a vehicle cabin, wherein the sound generator is configured to perform either or both of the following: increasing a sound pressure of the sound as the amount of operation of the pseudo clutch operation device increases, and increasing a frequency of the sound as the amount of operation of the pseudo clutch operation device increases.
