在临时驻车工况下,集成式电子液压制动(electronic hydraulic braking,EHB)系统持续保持一定的制动液压力,导致电机和EHB控制器严重发热。针对该工况,设计了基于有限状态机的控制模型与控制策略,以缓解发热问题。并根据该策略需求以及集成式EHB的工作特性设计了控制器硬件电路。通过台架实验和实车试验,验证了策略的正确性,达到了良好的效果。 Under temporary parking conditions, the integrated electronic hydraulic braking (EHB) system continuously maintains a certain brake fluid pressure, causing severe heating of the motor and EHB controller. According to this condition, a control model and control strategy based on finite state machine are designed to alleviate the heat problem. According to the demand of this strategy and the working characteristic of the integrated EHB, the controller hardware circuit is designed. Through the bench test and real vehicle test, the correctness of the strategy is verified and the good result is achieved.
