Abstract

The invention provides an electric vehicle which can safely enjoy both driving like an MT vehicle and driving as a normal EV. The electric vehicle is configured so as to be able to select traveling by an MT mode, which is a mode in which an electric motor is controlled using torque characteristics such as an MT vehicle having a manual transmission and an internal combustion engine, and traveling by an EV mode, which is a mode in which the electric motor is controlled using normal torque characteristics. When the selection of the travel mode is changed by the driver, the control device for the electric vehicle determines whether or not the control mode can be switched on the basis of the state of the vehicle detected by the external sensor, and switches the control mode in accordance with the determination result.

Description

technical field [0001] The present invention relates to an electric vehicle using an electric motor as a power unit for traveling. Background technique [0002] An electric motor used as a driving power unit in an electric vehicle (EV: Electric Vehicle) has a significantly different torque characteristic than an internal combustion engine used as a driving power unit in a conventional vehicle (CV: Conventional Vehicle). same. Due to the difference in the torque characteristics of the power plant, a transmission is necessary for a CV, but generally an 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 with MT (hereinafter referred to as MT vehicle) and driving an EV. [0003] On the other hand, electric motors can relatively easily control the torque by con...
