Problems solved by technology

In addition, it is assumed that the switch to the MT mode will be performed relatively frequently under various circumstances such as differences in the driving environment, the driver's mood, and when the driver is changed.
Therefore, if the driver's operation for switching to the MT mode becomes complicated, it may cause trouble to the driver.

Abstract

The present invention provides an electric vehicle that can enjoy both driving as a normal EV and driving as an MT vehicle, and that can be easily switched to driving as an MT vehicle by a driver. The electric vehicle is configured to be able to perform running by an MT mode that controls an electric motor with a torque characteristic like an MT vehicle having a manual transmission and an internal combustion engine, and running by an EV mode that controls the electric motor with a normal torque characteristic. The electric vehicle includes a mode changeover switch for switching to the running by the MT mode.

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 power unit for running in an electric vehicle (EV: Electric Vehicle) has a torque characteristic that is significantly different from an internal combustion engine used as a power unit for running in a conventional vehicle. Due to the difference in the torque characteristics of the power plant, conventional vehicles must have a transmission, but general EVs do 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 of a conventional vehicle with MT (hereinafter also referred to as "MT vehicle") and driving of an EV. [0003] On the other hand, electric motors can relatively easily control the torque by cont...
