The invention discloses a backup system of an integrated electric control brake boosting system. The system mainly comprises a body and the like; a left front oil path input port in the body is connected with a left front oil path cut-off valve; the left front oil path cut-off valve is connected to a left front oil path output port through a left front pressurizing valve; a left front pressure reducing valve is arranged between the left front pressurizing valve and the left front oil path output port; a right front oil path input port in the body is connected with a right front oil path cut-off valve; the right front oil path cut-off valve is connected to a right front oil path output port through a right front pressurizing valve; a right front pressure reducing valve is arranged between the right front pressurizing valve and the right front oil path output port; the pressurizing end of a pressurizing pump A is connected to the outlet of the left front oil path cut-off valve; and the pressurizing end of a pressurizing pump B is connected to the outlet of the right front oil path cut-off valve. With the backup system of the invention adopted, the two oil paths of the front wheels ofa vehicle can be controlled; and the braking redundancy function of the vehicle is achieved when a braking system fails; the failure probability of the integrated electric control brake boosting system is greatly reduced; the overall reliability of the system is improved; and safety is improved.
本发明公开了一种集成式电控制动助力系统的备份系统,主要包括本体等,本体内左前油路输入口连接左前油路切断阀,左前油路切断阀再通过左前加压阀连到左前油路输出口,左前加压阀和左前油路输出口之间设有左前减压阀,本体内右前油路输入口连接右前油路切断阀,右前油路切断阀再通过右前加压阀连到右前油路输出口,右前加压阀和右前油路输出口之间设有右前减压阀,加压泵A加压端连接到左前油路切断阀出口,加压泵B加压端连接到右前油路切断阀出口。本发明能够控制车辆前轮的两路油路,在制动系统失效的时候实现车辆的制动冗余功能;大大降低了集成式电控制动助力系统失效的概率,提高了系统整体的可靠性,提高了安全性。
