The invention discloses a multi-axle steering system for a multi-axle vehicle. Each vehicle wheel is provided with an electric control hydraulic steering device to control the rotation direction of the vehicle wheel; the electric control hydraulic steering device comprises a motor, a reversing valve and a steering hydraulic cylinder, an electronic control unit drives a valve element of the reversing valve to move between a first position and a second position through the motor, and a piston of the steering hydraulic cylinder is connected with the valve element. The motor drives the valve element of the reversing valve to switch the positions to enable oil to enter into a rod cavity or a non-rod cavity of the steering hydraulic cylinder to control the piston of the steering hydraulic cylinder to move, and then the valve element of the reversing valve is reversely driven to move to seal an oil hole of the reversing valve; a main oil pump is made to stop supplying the oil, and therefore the piston of the steering hydraulic cylinder stops moving. The electric control hydraulic steering device itself has a closed-loop control function, therefore, the multi-axle steering system just needs to be set as a simple open-loop control system, the structure is simple, and the accurate steering control over the multi-axle vehicle can be achieved.
