According to the electro-hydraulic steering system with the remote control and automatic aligning functions and the control method, the electro-hydraulic steering system can be suitable for vehicles with large loads, and the electro-hydraulic steering system is provided with an electric and hydraulic steering gear, a hydraulic oil cylinder and a mechanical rod system for power-assisted steering; redundancy design is adopted, safety and reliability are higher, the angle of the angular displacement sensor 4 and signals of an angle sensor and a torque sensor in the electric power steering gear 2 are detected through differential mechanism design, and safety and reliability are high through redundancy design. Low-speed large-torque assistance can be realized through vehicle speed detection, so that convenience is brought to driving while working, and assistance can be stopped at high speed; the steering clearance is reduced, and the high-speed stability is improved; through vehicle speed detection, according to signals of an angular displacement sensor, power-assisted steering return is carried out, and the real zero position return function is achieved; a remote control steering mode is provided, and steering remote control operation at different speeds is carried out.
