| 摘 要： | 对电动轿车制动过程中前后轴制动力关系及其对稳定性的影响进行了分析，提出一种电液复合制动控制策略。该策略在满足驾驶员制动感觉的前提下，符合法规对制动过程的要求。通过不同附着路面上的仿真对控制策略进行了验证。结果表明：为了满足制动法规的要求，在不同附着系数的路面上尤其在低附着系数路面上，为了避免前轮抱死而出现不稳定的危险工况，应该将电机制动力进行限制。同时，通过测功机对电机制动过程中对电池组的回馈电流大小进行了台架试验，并基于测试数据对基本市区工况进行了模拟。

| Abstract: | The front and rear brake forces of the electric automobile are analyzed and the braking stabil-ity is studied . A control strategy is proposed to coordinate the hydraulic and regenerative brake , which can satisfy the driver’s brake feeling ,and follow the brake regulation .The simulation is con-ducted on the different friction roads to validate the proposed method ;and the result show s that the moment of the motor must be limited to avoid locking the front w heels according to the regulation es-pecially on the roads with low friction coefficient .Finally ,the basic urban driving condition is simula-ted with the experimental data from the bench test . |
