摘　　要：以某型履带车辆为研究对象,进行发动机制动力的分析和计算,结合辅助制动系统的液力辅助制动力,提出了基于驱动轮轴最大可承受减速度(不发生抱死)的制动力分配控制策略。在车辆制动过程中,优先采用液力减速器进行制动,其次为摩擦制动和发动机联合制动,联合制动优先采用发动机制动,其次为摩擦制动。进行基于该制动策略的车辆制动建模和典型工况的仿真,结果表明:所提出的辅助制动控制策略能够确保车辆实现安全可靠的制动,是正确可行的。Focusing on a tracked vehicle auxiliary braking system,modeling and simulation of engine braking were conducted.An optimal control strategy of auxiliary braking was put forward.When there was no hydraulic braking,engine brake force could be used effectively by gearbox shift strategy to reduce the braking force requirements for frictional brakes based on the calculated results of engine braking.When there was hydraulic braking,the braking priority sequence was auxiliary braking,engine braking,and finally frictional braking.A forward simulation model for auxiliary braking system of tracked vehicle was built.The simulation and analysis under typical driving cycles were conducted.The results show that the control strategy and the models are reasonable and feasible.
