摘要: 针对当前混合动力汽车制动系统存在电机再生制动力和液压摩擦制动力一起工作而带来的相关问题,设计了双电机前轴复合制动系统。以前后轴制动力分配比例、ECE制动法规、电机特性、储能装置特性等因素为约束条件,研究了基于分层控制的混合动力汽车复合制动控制协调策略;利用MATLAB/Simulink对3种制动工况的制动力进行了仿真分析。结果表明:对汽车复合制动力实施层次协调控制后,复合制动力与驾驶员需求制动力误差有较明显降低,说明协调控制后车辆的制动舒适性有较大提高。

Abstract: In view of the current existing problems of related to motor regenerative braking and hydraulic friction braking work together, composite brake system with double motor was designed. Based on hierarchical control, a braking force distribution strategy of composite braking system was developed, considering the restriction of the distribution ratio of braking force upon front and rear, ECE braking regulation, motor characteristic and energy storage characteristic, etc. Finally the simulation of control strategy of composite braking system in MATLAB/Simulink environment was done under three operating modes. The results indicate friction braking system and motor regenerative braking system can work coordinately and steadily in various operating mode under the regenerative braking control strategy, and show that the error of composite braking force and braking force driver demand reduce significantly, vehicle brake comfort has improved greatly.

Key words: vehicle engineering, composite braking force, multi-constraints, hierarchical control, coordinated control
