The invention provides a walking driving hydraulic braking system, a control method and an engineering vehicle. The braking system comprises a walking motor, an engine, a main pump and a control unit. The main pump is in coaxial driving connection with the engine, and a first connecting oil way and a second connecting oil way are arranged between the main pump and the walking motor. The control unit is electrically connected with the engine and the main pump and is configured to obtain a driving signal of the vehicle; judging the current driving state of the vehicle according to the driving signal of the vehicle; when the vehicle is in the starting stage, the rising duration of the output displacement of the main pump is controlled to be prolonged, so that the output displacement of the main pump of the vehicle in the starting stage is changed more slowly, and the vehicle is started more stably without obvious impact; when the vehicle is in the braking stage, the output displacement descending duration of the main pump is controlled to be shortened, the output displacement of the main pump is rapidly zero in the braking stage, and the reliability and stability of the vehicle in the braking process are guaranteed.
本发明提供一种行走驱动液压制动系统、控制方法及工程车辆,该制动系统包括行走马达、发动机、主泵和控制单元。主泵与发动机同轴驱动连接,主泵和行走马达之间设有第一连接油路和第二连接油路;控制单元与发动机和主泵均电连接并被配置为:获取车辆的行驶信号;根据车辆的行驶信号判断车辆当前的行驶状态;当车辆处于起步阶段时,控制延长主泵的输出排量上升时长,使得车辆在起步阶段的主泵输出排量变化更加缓慢,车辆起步更加平稳,无明显冲击;当车辆处于刹车阶段时,控制缩短主泵的输出排量下降时长,在刹车阶段主泵的输出排量迅速将为0,保证了车辆刹车过程的可靠性和平稳性。
