The invention discloses a vehicle anti-skid control system for a two-wheeled electric vehicle and the two-wheeled electric vehicle, and the control system comprises a front wheel sensor which is used for measuring the number of rotation turns of a front wheel in real time and transmitting the number of rotation turns of the front wheel to a motor controller; the motor position sensor is used for acquiring the rotating speed of the motor in real time and transmitting the rotating speed of the motor to the motor controller; the motor controller is used for receiving the front wheel rotation turns and the motor rotation speed, determining the front wheel speed according to the front wheel rotation turns and determining the rear wheel speed according to the motor rotation speed; the motor controller is further used for determining the current slip speed difference ratio of the two-wheel electric vehicle according to the front wheel speed and the rear wheel speed and controlling the rotating speed of the motor according to the current slip speed difference ratio so that the current slip speed difference ratio can be smaller than a first preset slip speed difference ratio. According to the embodiment of the invention, the risk that the vehicle falls and is out of control is reduced, the current slip speed difference ratio is calculated according to the front wheel speed and the rear wheel speed, and the wheel speed is controlled through the current slip speed difference ratio, so that the wheel speed control precision is higher.
本发明公开了一种两轮电动车车辆防滑控制系统和两轮电动车,控制系统包括:前轮传感器用于实时测量前轮旋转圈数,并将前轮旋转圈数传输给电机控制器;电机位置传感器用于实时获取电机转速,并将电机转速传输给电机控制器;电机控制器用于接收前轮旋转圈数和电机转速,根据前轮旋转圈数确定前轮速度,根据电机转速确定后轮速度;电机控制器还用于根据前轮轮速和后轮轮速确定两轮电动车的当前滑移速差比,并根据当前滑移速差比控制电机转速,以使当前滑移速差比小于第一预设滑移速差比。本发明实施例降低了车辆摔车和失控的风险,根据前轮速度和后轮速度计算当前滑移速差比,并通过当前滑移速差比控制轮速,使得轮速控制精度更高。
