The invention provides a commercial vehicle drive-by-wire pneumatic braking redundant system and method. The system comprises a redundant power source, a front redundant module and a rear redundant module, wherein the redundant power source, the front redundant module and the rear redundant module are independent of an existing drive-by-wire pneumatic braking system on a vehicle. The front redundancy module and the rear redundancy module are independent of each other, and an air outlet of the front redundancy module outputs control air with set pressure to a control air port of the single-channel pressure control module, so that the single-channel pressure control module outputs required braking pressure to drive a brake of a front axle to realize vehicle braking; and the air outlet of the rear redundancy module outputs the control air with the set pressure to the control air port of the dual-channel pressure control module, so that the dual-channel pressure control module outputs the required braking pressure to drive a brake of a rear axle to realize vehicle braking. The system is high in braking force output linearity, has an anti-lock function, is comfortable, safe and reliable in braking, and meets functional safety requirements.
本发明提供一种商用车线控气压制动冗余系统及方法,所述系统包括与车上已有的线控气压制动系统相互独立的冗余电源、前冗余模块以及后冗余模块;所述前冗余模块和后冗余模块相互独立,前冗余模块的出气口向单通道压力控制模块的控制气口输出设定压力的控制气体,使单通道压力控制模块输出所需制动压力以驱动前桥的制动器实现车辆制动;后冗余模块的出气口向双通道压力控制模块的控制气口输出所述设定压力的控制气体,使双通道压力控制模块输出所需制动压力以驱动后桥的制动器实现车辆制动。本发明的系统制动力输出线性度高,且具备防抱死功能,制动舒适、安全、可靠,满足功能安全要求。
