摘要

为提高电动汽车的制动性能和回收效率,设计了一种基于直驱电液单元的线控制动系统,实现了制动力的灵活独立调节。详细讨论了制动单元的结构和制动系统的组成。由于该系统摩擦力控制灵活,能很好地与再生系统协调,因此对再生策略进行了详细讨论。最后,建立了基于Matlab/Simulink和AMESim的电动汽车模型,验证了该系统能够根据电机状态灵活控制摩擦力,显著提高了再生效率。

Research on regenerative technology of EV based on direct-drive electric-hydraulic brake unit
A novel brake-by-wire system based on direct-drive electro-hydraulic unit, which regulates braking force flexibly and dependently, was designed for electric vehicles to improve braking performance and recovery efficiency. The structure of brake unit is discussed in detail as well as the composition of brake system. Since this novel system is well to coordinate with regenerative system because of flexibly controlled friction force, the regenerative strategy is discussed in detail. At last, a electric vehicle model based on Matlab/Simulink and AMESim is established to verify that this novel system is able to control friction force flexibly according to motor status and the regenerative efficiency is significantly improved.
