The invention discloses a hydrostatic driving walking electric control system which comprises a walking controller, an engine ECU, an accelerator pedal, a brake pedal, a forward/backward switch, a motor rotating speed sensor, a motor pressure sensor, a pump displacement forward electromagnetic valve, a pump displacement backward electromagnetic valve and a motor displacement electromagnetic valve. The accelerator pedal realizes the rotation speed regulation of the engine, regulates the displacement of the pump and the motor according to the rotation speed of the engine, realizes the stepless speed regulation of driving, can sense the driving speed and the driving resistance in real time, further feeds back and regulates the rotation speed of the engine and the displacement of the pump and the motor, and realizes the effective combination of the driving speed and traction force. According to the electric control system, stepless speed regulation in the driving process can be achieved, the rotating speed of the engine and the displacement of the pump and the motor can be adjusted in real time according to the driving speed and resistance, the problems of power loss, time delay and impact caused by gear shifting operation of a gearbox are solved, and the problems of overload and speed reduction of the engine are solved.

    本发明公开一种静液压驱动行走电控系统,包括行走控制器、发动机ECU、油门踏板、制动踏板、前进/后退开关、马达转速传感器、马达压力传感器、泵排量前进电磁阀、泵排量后退电磁阀、马达排量电磁阀,挂上前进或后退档后,油门踏板实现发动机的转速调节,根据发动机的转速调节泵和马达的排量,实现行车无级调速,并可以实时感知行车速度和行车阻力,进而反馈调节发动机转速、泵和马达排量,实现行车速度和牵引力的有效结合。该电控系统既可实现行车过程的无级调速又可以根据行车速度和阻力实时调节发动机的转速以及泵和马达排量,既解决了变速箱换挡操作带来的功率损失、延时和冲击问题,又解决了发动机过载掉速的问题。
