The invention relates to an electric vehicle with tracking and antiskid functions. The electric vehicle comprises a power battery, an accelerator handle, a motor, a motor controller, a driving control unit, a rear wheel and a front wheel. The motor controller is electrically connected with the power battery, the accelerator signal sensor and the motor, receives the accelerator opening signal and the motor phase information, controls the power battery to output a corresponding power supply to the motor, and stores a load reduction coefficient database. The motor angle sensor obtains the rotating speed information of the motor and calculates the rear wheel speed of the rear wheel, and the motor controller receives the front wheel rotating speed information measured by the front wheel rotating speed sensor and calculates the front wheel speed of the front wheel. The motor controller can calculate the slip ratio of the front wheel speed and the rear wheel speed after receiving the information of the front wheel speed and the rear wheel speed, and the motor controller inquires the data of the load reduction coefficient database to limit the power output of the motor according to the corresponding relation of the slip ratio and the rear wheel speed, so that the torque of the rear wheel is reduced to recover the road holding force, and the tire slip condition is avoided.

    本发明是有关于一种具循迹防滑功能的电动车辆,包括有一动力电池、一油门把手、一马达、一马达控制器、一行车控制单元、一后轮以及一前轮。马达控制器电连接动力电池、油门信号传感器以及马达,接收油门开度信号及马达相位信息,控制动力电池输出对应的电源至马达,马达控制器储存一降载系数数据库。马达角度传感器取得马达的转速信息,并计算出后轮的后轮速,马达控制器接收来自前轮转速传感器所测得的前轮转速信息,并计算出前轮的前轮速。其中,马达控制器接收前轮速与后轮速的信息后可计算前后轮速的滑差率,马达控制器依据滑差率与后轮速的对应关系,查询降载系数数据库的数据限制马达的动力输出,使后轮扭力下降以致恢复抓地力,避免轮胎打滑的情况发生。
