Abstract

The invention provides an electric vehicle, which belongs to the technical field of transportation and solves the problem that an existing electric vehicle runs unstably and completely loses power if a motor fails. The electric vehicle comprises a frame and a vehicle controller, two front wheels are positioned at the front end of the frame, two rear wheels are positioned at the rear end of the frame, a power battery system and two driving motors are fixed into the frame, one of the driving motors is mechanically connected with the two front wheels by speed change structures, the other driving motor is mechanically connected with the two rear wheels by speed change structures, both of the two driving motors are electrically connected with the power battery system by motor controllers, and both of the two motor controllers are electrically connected with the vehicle controller. The front wheels and the rear wheels of the electric vehicle are independently driven and can be independently controlled, accordingly, a front-wheel-drive mode, a rear-wheel-drive mode and a four-wheel drive mode can be actuated according to a control strategy in the vehicle controller, the vehicle meets requirements of different road conditions, and the systematic efficiency is optimized.
