Vehicle composite braking control method, device and system, as well as vehicle composite braking controller

Abstract

The invention discloses a vehicle composite braking control method, device and system, as well as a vehicle composite braking controller. The method comprises the following steps: calculating to determine a total braking force needed by a vehicle, and calculating to determine exerted braking forces needed by various braking modes, respectively distributing the braking forces to the corresponding controller, and realizing vehicle braking by the controller in response to the distributed output braking forces. The method, device and system, as well as the controller are capable of solving problems that in the prior art, braking force response is slow, the efficiency is low and the reliability is poor, and have the advantages of better braking control efficiency, better reliability and the like.

Description

technical field [0001] The invention relates to the field of vehicle braking control, in particular to a vehicle hybrid braking control method, device, controller and system, which is suitable for subways, monorail vehicles, light rails, low floors, and locomotives with both electric braking and friction braking and motor vehicles and other vehicles. Background technique [0002] Train braking is divided into electric braking and friction braking. In the actual operation of trains, a hybrid braking method in which electric braking and friction braking cooperate with each other is usually used. The hybrid braking control commonly used in the field of rail transit is completed by the cooperation of the traction system control unit (DCU), the braking system control unit (BCU) and the train control and diagnostic system (TCMS), in which the electric braking and friction braking are respectively controlled by DCU and BCU manage and control respectively, or TCMS participates in ...
