The invention relates to the technical field of engineering vehicles, and particularly discloses a brake system, a redundancy brake control method and a vehicle, a high-pressure air storage bag, a service brake valve and a service brake chamber of a spring parking brake are sequentially connected in series, and the high-pressure air storage bag, a parking brake valve, a redundancy brake valve and a parking brake chamber of the spring parking brake are sequentially connected in series; the service brake valve can enable the high-pressure air storage bag to be communicated with the service brake chamber, and can also enable the service brake chamber to be communicated with the atmosphere; the redundant brake valve can enable the parking brake valve to be communicated with the parking brake cavity, the parking brake cavity can be communicated with the atmosphere, the parking brake valve can enable the redundant brake valve to be communicated with the high-pressure air storage bag and can also enable the redundant brake valve to be communicated with the atmosphere, and the redundant controller receives vehicle state information and controls the redundant brake valve. According to the redundant braking control method, when parking is misunderstood or service braking fails, braking of the wheels is achieved by controlling the redundant braking valve, and then the safety of vehicle driving is improved.
本发明涉及工程车辆技术领域,具体公开了制动系统、冗余制动控制方法及车辆,高压储气包、行车制动阀和弹簧驻车制动器的行车制动腔室依次串联,高压储气包、驻车制动阀、冗余制动阀和弹簧驻车制动器的驻车制动腔室依次串联,行车制动阀可使高压储气包和行车制动腔室连通,也可使行车制动腔室与大气连通;冗余制动阀可使驻车制动阀和驻车制动腔室连通,也可使驻车制动腔室与大气连通,驻车制动阀可使冗余制动阀和高压储气包连通,也可使冗余制动阀与大气连通,冗余控制器接收车辆状态信息且控制冗余制动阀。冗余制动控制方法可以在驻车误解除或行车制动失效时,通过控制冗余制动阀,实现对车轮的制动,进而提升了车辆驾驶的安全性。
