32、h 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,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

33、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

34、property rights.,制动安全与控制系统,EBV工作过程减压,EBV的升压与保压与ABS工作情况一致。但减压控制则有不同。当后轮有抱死倾向时，后轮的常开阀关闭，常闭阀打开，车轮压力降低，与ABS不同的是：此时液压泵不工作，降压排放出来的制动液暂时储存在低压蓄能器中。,38,Duan Yongshan|25/01/2011|Robert Bosch GmbH 2011.All rights reserved,also regarding any disposal,exploitation,reproduction,editing,distribution,as well as in

35、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,editi

36、ng,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
