摘要
开发了具备机械备份的线控液压制动阀并对其控制性能进行了试验和分析。以线控制动系统为基础,建立了燃料电池汽车线控串行复合制动系统,并设计了与之相适应的电液复合制动控制算法。对串行复合制动过程进行了硬件在环仿真。结果表明,该系统实现了电机再生制动与液压摩擦制动的串行施加,有效提高了制动能量回收率。
A brake-by-wire（BBW） hydraulic brake valve with mechanical backup is developed and its control performance is tested and analyzed.Based on BBW,a series hybrid brake system for a fuel-cell vehicle is built with corresponding control algorithm for electro-hydraulic braking designed.A hardware-in-the-loop simulation on series hybrid braking process is conducted.The results show that the system achieves the series application of motor regenerative braking and hydraulic friction braking,effectively enhancing braking energy recovery rate.
