摘要: 针对高速电驱动履带车辆机械制动器、电机和电液缓速器3种执行部件联合制动转矩响应的问题,提出了机械制动器、电机和电液缓速器动态协调控制策略。基于制动需求和车速等因素进行稳态制动力分配,综合考虑3种执行部件动态响应特性,建立基于电机-电液缓速器二者联合制动和机械-电机-电液缓速器三者联合制动转矩动态协调控制策略,搭建面向工程应用的电驱动履带车辆传动系统仿真模型,利用实时仿真工具进行策略验证。仿真结果表明,在整个制动过程中该动态协调控制策略可提高车辆总制动转矩响应速度和精度,改善系统动态响应特性。

Abstract: A dynamic coordinated control strategy of mechanical brake, motor and electro-hydraulic retarder is proposed for the torque response of composite braking of mechanical brake, motor and electro-hydraulic retarder in high speed electric drive tracked vehicle. The steady-state braking torque is assigned based on braking requirement and vehicle speed, and the dynamic response characteristics of three executive components are considered comprehensively. Based on the dynamic coordinated control strategy for the composite braking of motor and electro-hydraulic retarder and the composite braking of mechanical brake, motor and electro hydraulic retarder, a simulation model of electric drive tracked vehicle transmission system is established, making use of real-time simulation tool to verify the strategy. The simulated results show that the dynamic coordinated control strategy can be used to enhance the response speed of total braking torque, and improve the dynamic response characteristics of the vehicle during braking.
