2011.All rights reserved,also regarding any disposal,exploitation,reproduction,editing,distribution,as well as in the event of applications for industrial property rights.,制动安全与控制系统,电子制动力分配EBV,EBV,ABS,在车轮部分制动时,EBV就开始起作用,控制单元根据转速传感器车速传感器信号计算轮速及滑移率。如果后轮滑移率大于某个设定值,则液压单元调节后轮制动力,使后轮制动力下降,以保证后轮不会先于前轮抱死。EBV的控制与传统的制动力分配(比例阀)相比,EBV保证了较高的车轮附着力及合理的制动力分配。同时EBV没有增加任何零件而是通过软件来控制,降低了成本。当ABS开始工作,EBV停止工作。,37,Duan Yongshan|25/01/2011|Robert Bosch GmbH 2011.All rights reserved,also regarding any disposal,exploitation,reproduction,editing,distribution,as well as in the event of applications for industrial

rights reserved,also regarding any disposal,exploitation,reproduction,editing,distribution,as well as in the event of applications for industrial property rights.,制动安全与控制系统,EBV工作过程踏板释放后,当制动结束后,制动踏板松开,总泵内的制动压力为零,此时再次打开常闭阀及常开阀,低压蓄能器的制动液经常闭阀、常开阀流回制动总泵,低压蓄能器排空,为下次ABS或EBV功能做好准备。,39,Duan Yongshan|25/01/2011|Robert Bosch GmbH 2011.All rights reserved,also regarding any disposal,exploitation,reproduction,editing,distribution,as well as in the event of applications for industrial property rights.,制动安全与控制系统,加速防滑装置主要是在地面附着系数较低,而负荷相对较大的情况下发挥作用。当驱动轮出现打滑时,车辆牵引力下降,此时ASR功能被触发。ASR功能执行进行打滑驱动轮的制动,降低打滑量,降低发动机转速,变速器向低档切换,通过一系列降速增扭的动作,实现控制目的。如果是两侧驱动车轮同时出现上述情况,只有ASR进行工作,如果两侧驱动车轮的附着系数不同,那么车轮打滑量也不相同,此时在ASR工作的同时,EDS被激活,共同参与,辅助车辆起步。,ASR工作原理,40,Duan
