| 摘 要： | 为解决ABS逻辑门限值方法匹配成本高、周期长的问题,将制动器耗散功率原理应用于匹配中.结合逻辑门限值与制动器耗散功率的各自优点,将制动器耗散功率原理能自适应识别各种路面状况的特点应用于匹配中;根据制动器耗散功率极大值对应的滑移率略小于临界滑移率且相差不大的原理,采用制动器耗散功率极大值对应的滑移率代替峰值附着系数对应的滑移率对ABS进行控制;滑移率与制动器耗散功率曲线获得较为简单,因此可以大大提高匹配效率.经过实车匹配验证,本方法提高了匹配效率和控制质量,节约了匹配成本.

| Abstract: | In order to solve the problem of the high cost and long period of ABS calibration and matching using threshold control method,the theory of brake decay power was applied to ABS calibration.The shortages of conventional method of matching ABS were analyzed.Utilizing the advantages of threshold method and brake decay power theory,the ABS calibration and matching method for vehicle based on brake decay power theory was put forward.According to theory that the slip rate by max of brake decay power approaches sl... |
