纯电动车真空助力系统的匹配测试研究
|
摘要
纯电动车的真空源由电子真空泵提供,其供气能力直接决定整车制动的安全性与舒适性,如制动距离与踏板感,在紧急制动或者连续踩制动时,真空的储备提供能力尤为重要,文章对真空助力系统中电动真空泵、真空助力器以及控制逻辑(电动真空泵的启/停阈值)的匹配工作进行了实验测试,通过多次模拟测定,确定了三者之间的关系,该测试研究总结出了真空助力系统的测试方法、规律特性,为后续开发车型进行相关匹配提供了参考。
EVP provide vacuum for the electric vehicle, Vacuum pumping capacity is directly related to the safety and comfort of vehicle braking function, eg braking distance and pedal feeling, especially in emergency or continuous braking,vacuum pumping ability is particularly important, authors carried out matching tests of vacuum booster, vacuum pump and control logic(the on-off threshold value of vacuum pump), after several simulation tests, authors determined the relationships between vacuum tank and vacuum booster, authors summarizes the experimental testing methods and rules, It provides reference for subsequent development of vehicle matching.
