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.

Claims (9)

1. An electric vehicle configured to use an electric motor as a power device for traveling, the electric vehicle comprising:

a controller having an operation mode in which the electric motor is operated to simulate a torque characteristic of a manual transmission vehicle by using a manual transmission model, the manual transmission model being a model of an imaginary manual transmission, wherein

the operation mode includes an automatic shift mode in which a gear stage of the imaginary manual transmission is automatically upshifted or downshifted,

upshifting of the gear stage of the imaginary manual transmission is performed when an imaginary engine speed is increased to an upshift reference speed,

downshifting of the gear stage of the imaginary manual transmission is performed when the imaginary engine speed is reduced to a downshift reference speed, and

the downshift reference speed is set to a lower speed than the upshift reference speed.

2. The electric vehicle according to claim 1 , wherein the automatic shift mode is performed using a shift pattern map, the shift pattern map being prepared separately for the upshifting and for the downshifting.

3. The electric vehicle according to claim 1 , further comprising:

a pseudo-gearshift configured to allow manual shifting of the gear stage of the imaginary manual transmission.
