The invention discloses an electric vehicle braking system capable of achieving automatic drifting, a control method and an electric vehicle, relates to the field of new energy vehicles, and can be applied to pure electric vehicles and hybrid vehicles. The braking system comprises a central controller and a plurality of wheel end braking devices. And each wheel end braking device is used for outputting braking force to a brake disc of one wheel so as to brake the electric automobile. When the speed of the electric automobile is larger than a speed threshold value in the driving process, the central controller is used for controlling the electric automobile when the opening degree of an accelerator pedal of the electric automobile is smaller than an accelerator threshold value, the opening degree of a brake pedal of the electric automobile is smaller than a brake threshold value, the rotating angle of a steering wheel of the electric automobile is larger than an angle threshold value and the steering angle of the electric automobile is smaller than a drifting threshold value. And controlling wheel end braking devices corresponding to rear wheels of the electric automobile to output braking force. According to the scheme, drifting can be achieved only through simple operation, the drifting operation threshold is lowered, and the driving experience of the vehicle is improved.

    一种实现自动漂移的电动汽车制动系统,控制方法和电动汽车,涉及新能源汽车领域,可应用于纯电动车辆及混动车辆。制动系统包括中央控制器和多个轮端制动装置。每个轮端制动装置用于向一个车轮的刹车盘输出制动力以制动电动汽车。中央控制器用于在电动汽车的车速大于车速阈值的行驶过程中,当电动汽车的油门踏板的开度小于油门阈值、电动汽车的制动踏板的开度小于制动阈值、电动汽车的方向盘的转角大于角度阈值且电动汽车的转向角度小于漂移阈值,控制电动汽车的后轮对应的轮端制动装置输出制动力。根据本方案,只需要进行简单操作即可实现漂移,降低了漂移的操作门槛,提高车辆的驾驶体验。
