The invention relates to a proportional valve type brake-by-wire system and a control method thereof, belongs to the technical field of unmanned wide-body dump trucks, and solves the problems of high cost and complex structure of brake-by-wire brake of a mining dump truck in the prior art that a front axle, a middle axle and a rear axle brake system are controlled by a central controller. The first air inlet of the proportional valve assembly is connected with the first air storage cylinder and the first relay valve, the second air inlet of the proportional valve assembly is connected with the second air storage cylinder and the second relay valve, and the driving relay valve is controlled through the proportional valve, so that the basic requirements of a whole vehicle brake-by-wire system are met; the drive-by-wire brake system has the advantages that the structure of components is simplified, the system cost is reduced, the function and control logic of the drive-by-wire brake system better meet the use requirements of the working scene of mining transportation vehicles, and the application of the drive-by-wire brake system in the field of unmanned mining dump trucks is further widened.

    本发明涉及一种比例阀式线控制动系统及其控制方法,属于无人驾驶宽体自卸车技术领域,解决了现有技术中矿用自卸车的线控制动通过中央控制器控制前桥、中桥和后桥制动力系统,其成本高、结构复杂的问题。本发明比例阀总成的第一进气口分别于第一储气筒和第一继动阀连接,比例阀总成的第二进气口分别于第二储气筒和第二继动阀连接,通过比例阀控制行车继动阀满足了整车线控制动系统基本需求的前提下,简化部件结构、降低系统成本,并使得其功能和控制逻辑更符合矿区运输车辆工作场景的使用需要,进一步拓宽了线控制动系统在无人驾驶矿用自卸车领域的应用。
