The invention discloses a redundant braking system of a low-speed automatic driving commercial vehicle and a precise parking method. According to the redundant braking system, hardware such as control valves is additionally arranged, so that a set of redundant braking assemblies independent of the EBS system are provided, redundant air paths from air cylinders to corresponding braking air chambers are formed, and all the redundant braking assemblies are directly controlled by the automatic driving system; even if the EBS front axle module, the EBS rear axle module, the trailer proportional valve and other control components in the EBS system do not work, the redundant braking system can still work stably, safely and reliably through the redundant braking control assembly. The redundant braking system is suitable for most low-speed unmanned commercial vehicles using air path braking systems, redundant braking control can be provided, and precise parking control during low-speed operation can also be provided.
本发明公开了一种低速自动驾驶商用车的冗余制动系统和精准停车方法。所述冗余制动系统通过增加控制阀类的硬件,以提供一套独立于EBS系统之外的冗余制动组件,形成储气筒到对应制动气室的冗余气路,各冗余制动组件直接受自动驾驶系统控制,即使EBS系统中的EBS前桥模块、EBS后桥模块和挂车比例阀等控制部件均不工作,本发明的冗余制动系统仍能通过冗余制动控制组件稳定安全可靠的进行工作。本发明的冗余制动系统适用于大部分的使用气路制动系统的低速无人驾驶商用车,不仅能提供冗余制动控制,还能提供低速运行时的精准停车控制。
