The invention provides a braking method, device and system for a motor train unit vehicle. The method comprises the steps that the electric braking capacity of the motor train and the total braking capacity of the motor train are sent to a motor train unit control unit, so that the motor train unit control unit determines the electric braking proportion of each motor train according to each electric braking capacity and the braking force needed by the motor train unit, determining the total braking capacity use proportion of each motor train according to each total braking capacity and the braking force required by the motor train unit; a first electric braking application value is determined according to the electric braking proportion and the electric braking capacity, and a second electric braking application value is determined according to the total braking capacity use proportion and the electric braking capacity; determining an offset proportion according to the wheel rail state data, the weather data and the wheel set sliding data; determining a target electric braking application value according to the offset proportion, the first electric braking application value and the second electric braking application value; and the target electric braking application value is sent to the traction control unit so that braking can be conducted according to the target electric braking force applied by the traction control unit, and the braking efficiency of the motor train unit vehicle can be improved.

    本发明提供一种动车组车辆的制动方法、装置及系统。该方法包括:将动车的电制动能力和车辆的总制动能力发送至动车组控制单元,以使动车组控制单元根据各电制动能力和动车组所需制动力确定各动车的电制动比例,根据各总制动能力和动车组所需制动力确定各动车的总制动能力使用比例;根据电制动比例和电制动能力确定第一电制动申请值,根据总制动能力使用比例和电制动能力确定第二电制动申请值;根据轮轨状态数据、天气数据和轮对滑行数据确定偏移比例;根据偏移比例、第一电制动申请值和第二电制动申请值确定目标电制动申请值;将目标电制动申请值发送至牵引控制单元以根据牵引控制单元施加的目标电制动力进行制动,可以提高动车组车辆的制动效率。
