The invention relates to a braking method, device and system of an electric vehicle, a medium, equipment and the vehicle. The electric vehicle includes a friction brake pedal and an electromagnetic brake pedal. The method includes the following steps: if a brake signal generated by rotation of the friction brake pedal is received, the electric vehicle is braked by using a friction braking technology; and if a brake signal generated by rotation of the electromagnetic brake pedal is received, the target torque of a motor is determined according to the opening degree of the electromagnetic brakepedal, and the motor is controlled to operate at the target torque in order to make the electric vehicle electromagnetically braked. Thus, when the vehicle continuously goes downhill, a driver can only step on the electromagnetic brake pedal and only apply electromagnetic brake, so the problem of heat attenuation of the brake can be solved to a certain extent. Moreover, when emergency braking is needed, the driver can only step on the friction brake pedal and only apply friction braking, and energy recovery is not carried out, so a control strategy is simplified.

    本公开涉及一种电动车辆的制动方法、装置和系统、介质、设备、车辆。所述电动车辆包括摩擦制动踏板和电磁制动踏板,所述方法包括:若接收到由所述摩擦制动踏板的转动产生的制动信号,则采用摩擦制动方法来制动所述电动车辆;若接收到由所述电磁制动踏板的转动产生的制动信号,则根据所述电磁制动踏板的开度确定电机的目标扭矩,并控制所述电机以所述目标扭矩运转,以使所述电动车辆电磁制动。这样,当连续下坡时,驾驶员可以仅踩下电磁制动踏板,仅应用电磁制动,在一定程度上能够解决制动器热衰减的问题。并且,在需要紧急制动时,驾驶员可以仅踩下摩擦制动踏板,仅应用摩擦制动,不进行能量回收,简化了控制策略。
