The invention discloses a coordinated control device for the electronic control suspension and the ABS. The control cylinder is set on the right side of the controlled piston rod of the active suspension system. The control cylinder is sealed with the electromagnet. The control cylinder is sealed and connected by the first interface of the oil pipe and the solenoid valve. The second interface of the solenoid valve is sealed with the brake sub pump of the ABS system. The third interface of the solenoid valve is connected with the brake fluid storage tank of the ABS system; the switch of the solenoid valve is controlled by three parallel relays. The opening and breaking of the control circuits of the three relays are controlled by the constant open valve, the normally closed valve and the hydraulic pump of the ABS system; the first, third interface is connected when the solenoid valve is in the state of power failure. When the solenoid valve is in an energized state, the first, second interfaces are connected. In the process of the ABS system, this invention can prevent the pressure displacement at the bottom of the car and the value of the lift on the rear of the car, which will fluctuate with the fluctuation of the braking force, and the passengers in the car will feel more comfortable.

一种电控悬架与ABS协调控制装置
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协调控制装置。
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,车轮抱死程度降低,车轮转速增大。(4)增压阶段为达到最佳制动效果,当车轮达到预定转速后,ABS电子控制单元控制常开阀14打开,常闭阀15关闭,随着制动压力的增加,车轮再次被制动和减速。从上述四个工作过程可以得出,当处于监测阶段时,ABS系统1只进行监测不进行实际动作,当ABS系统1发挥作用时,依次在保压阶段、降压阶段及增压阶段三者之间循环,这个过程中常开阀14、常闭阀15或者液压泵17处于受控工作状态,因此 ...
