The invention relates to an electric control hydraulic driving system for an industrial vehicle. Only one electromotor and one microcomputer controller are used for driving a variable pump to conduct frequency control so as to convey hydraulic oil in a hydraulic oil tank to a travelling mechanism, an inclining mechanism, a lifting mechanism, a steering mechanism, a kinetic energy recycling mechanism, a potential energy recycling mechanism and a travelling speed limiting mechanism; kinetic energy recycle, overload potential energy recycle, and no-load and light-load unloading can be realized while the vehicle realizes actions of travelling, inclining, lifting and steering; through the adoption of the travelling speed limiting mechanism, the vehicle speed can be limited, and the vehicle travelling can be stable; during slope sliding and braking, the hydraulic system can automatically supply oil; during slope climbing of the vehicle, the variable pump automatically varies according to the load pressure set value to achieve the low-speed large-torque slope climbing function, and the slope climbing current is low. The electromotor consists of a permanent-magnet brushless motor, an inverter controller and a variable piston pump; zero current start to a load current is realized, the starting time is within the millimeter-level range, large current starting can be avoided, and energy can be saved.
