摘　　要：针对新能源汽车制动时顶脚反弹、连续制动踏板踩不动和制动失效等问题,建立新能源汽车电子制动助力器力学模型并进行分析,基于MATLAB软件搭建新能源汽车三相永磁同步电机(Permanent Magnet Synchronous Motor,PMSM)的矢量控制模型并进行仿真,同时联合CarSim软件和Simulink软件对新能源汽车三相PMSM的制动效果进行仿真验证,最后搭建实车测试平台进行试验。结果表明,具备新型电子制动助力器的新能源汽车拥有更高的制动性能,制动距离更短。Aiming at the problems such as rebound of top foot,immobility of continuous brake pedal and brake failure during bra-king of new energy vehicles,a mechanical model of electronic brake booster of new energy vehicles was established and ana-lyzed,and a vector control model of three-phase Permanent Magnet Synchronous Motor(PMSM)of new energy vehicles was built and simulated based on MATLAB software.At the same time,CarSim and Simulink software were jointly used to simulate and verify the braking effect of three-phase PMSM of new energy vehicles,and finally a real vehicle platform was built for testing.The results show that the new energy vehicles with new electronic brake booster have higher braking performance and smaller braking distance.
