The invention provides an electronic mechanical braking device, an electric vehicle and a braking control method of the electronic mechanical braking device, and is applied to the technical field of electric vehicles so as to improve the braking precision when the electronic mechanical braking device brakes wheels. A controller in the electronic mechanical braking device receives a first braking signal and controls a braking motor to output a first braking torque at the first moment after the electronic mechanical braking device brakes the corresponding wheels. And then, at a second moment after the first moment, a second brake signal is received, and the brake motor is controlled to output a second brake torque. The difference value between the braking torque indicated by the first braking signal and the braking torque indicated by the second braking signal is smaller than a preset torque value, and the difference value between the second braking torque and the first braking torque is larger than the preset torque value. On the basis, the electronic mechanical braking device can dynamically adjust the braking torque output by the braking motor according to the temperature change of the friction plate, and therefore the braking precision of the electronic mechanical braking device when the wheels are braked is improved.

    本申请提供了一种电子机械制动装置、电动车辆及其制动控制方法,应用于电动车辆技术领域,以改善电子机械制动装置对车轮进行制动时的制动精度。其中,电子机械制动装置中的控制器在电子机械制动装置制动对应的车轮之后的第一时刻,接收第一制动信号并控制制动电机输出第一制动扭矩。然后,在第一时刻之后的第二时刻,接收第二制动信号并控制制动电机输出第二制动扭矩。第一制动信号指示的制动扭矩与第二制动信号指示的制动扭矩的差值小于预设扭矩值,第二制动扭矩与第一制动扭矩的差值大于预设扭矩值。基于此,电子机械制动装置可以根据摩擦片的温度变化动态调整制动电机输出的制动扭矩,从而提高电子机械制动装置在对车轮进行制动时的制动精度。
