A new type of built-in composite electromagnetic and frictional braking structural scheme and its corresponding coordinated control strategy were proposed to enhance the braking effects for the electric vehicle. Fuzzy control theory was applied to design the coordinated control strategy for the electromagnetic and frictional braking system. In comparison to lower braking strength and moderate braking strength, the slip ratio of high braking strength was maintained at near 0.15. It effectively avoided the wheel getting locked and provided relatively large braking torque in the process of braking. The integrated system using a fuzzy control strategy can effectively shorten the braking time, enhance the braking safety in the braking process.
为提高电动汽车的制动效果,提出了一种新型内置复合电磁与摩擦制动结构方案及其相应的协调控制策略。应用模糊控制理论设计电磁与摩擦制动系统的协调控制策略。与低制动强度和中等制动强度相比,高制动强度下的滑移率保持在0.15左右。它有效地避免了车轮抱死,并在制动过程中提供了相对较大的制动力矩。采用模糊控制策略的集成系统能够有效缩短制动时间,提高制动过程中的制动安全性。
