Abstract

Provided is an electric vehicle capable of experiencing a driving feeling of engine stall such as an MT vehicle. The control device for an electric vehicle uses an MT vehicle model to control the torque of an electric motor on the basis of the amount of operation of an acceleration pedal, the amount of operation of a simulated clutch pedal, and the shift stage of a simulated shift device. Furthermore, the control device executes a flameout deducing process for changing the engine output torque for calculating the drive wheel torque to zero when the rotation speed of the virtual engine calculated using the MT vehicle model is lower than a predetermined flameout rotation speed.

Description

technical field [0001] The present invention relates to an electric vehicle using an electric motor (electric motor) as a driving power unit. Background technique [0002] An electric motor used as a running power unit in an electric vehicle (EV: Electric Vehicle) has a torque characteristic that is significantly different from an internal combustion engine used as a running power unit in a conventional vehicle. Due to the difference in the torque characteristics of the power plant, a CV (combustion engine vehicle) must have a transmission, whereas a general EV does not have a transmission. Of course, EVs do not have a manual transmission (MT: Manual Transmission) in which a gear ratio is switched by a driver's manual operation. Therefore, there is a large difference in driving feeling between driving a conventional vehicle equipped with MT (hereinafter referred to as MT vehicle) and driving an EV. [0003] On the other hand, electric motors can relatively easily control t...
