一种电控悬架与ABS联动控制系统
本专利技术属于安装有ABS系统和主动悬架系统的汽车领域,尤其是一种电控悬架与ABS联动控制系统。
技术介绍
如图1所示,ABS系统1的四个工作过程如下:(1)监测阶段制动时,驾驶员通过脚踏板11控制制动总泵12/真空助力器13在制动管路中建立制动液压力,此时常开阀14开启,常闭阀15关闭,制动液压力进入车轮处的制动分泵16,车轮速度迅速降低,直到ABS电子控制单元通过轮速传感器得到的信号识别出车轮有抱死的倾向时为止(常开阀14在断电时处于开启状态,常闭阀14在断电时处于关闭状态)。(2)保压阶段ABS电子控制单元通过转速传感器得到的信号识别出车轮有抱死倾向时,ABS电子控制单元给常开阀14通电使其关闭,常闭阀15此时仍保持关闭,制动分泵16内的液压力保持不变。(3)降压阶段如果在保压阶段,车轮抱死倾向进一步加大,则进入降压阶段。此时,ABS电子控制单元给常闭阀15通电使其打开,常开阀14仍然关闭,ABS电子控制单元给液压泵17通电使其开始工作,制动液经低压蓄能器18被送回到制动总泵12。制动压力降低,脚踏板11出现抖动,车轮抱死程 ...
