电动汽车防抱死制动系统的研究

Study on Anti-Lock Braking System of Electric Vehicles

以纯电动车为研究对象,建立了车辆模型。在考虑汽车行驶安全性的基础上,以车轮滑移率为控制目标,分别进行了液压ABS制动和电机防抱死制动的研究,设计了液压ABS控制策略和电机防抱死控制策略,并进行了仿真实验,实验结果表明提出的控制策略能有效提高电动汽车的制动安全性。

Treating the Purely electric vehicles as research object, the vehicle model is established. Considering the driving safety of cars, the hydraulic ABS（Anti-lock Braking System） and motor ABS are both researched, which regard the slip ratio of wheels as the control target. Then a control strategy of hydraulic ABS and motor ABS are designed, with making a simulation experiment, the result shows that the proposed control strategy can effectively improve braking stability of the electric cars.
