The invention provides an automotive front wheel independent-control and hydraulic-steering system having a redundancy function. The system is composed of a steering wheel module (21), a hydraulic transmission system (18), hydraulic steering execution modules (15), an electronic control module (13), a steering wheel (1), a steering shaft (2), a gear (19), a rack (3), pistons (20), hydraulic oil cylinders (4), oil pipes (6), a flow control valve (17), electric three-way valves (7), executing oil cylinders (8), magnetic control devices (9), compensation oil tanks (10), switch type control valves (14), steering cross pull rods (16), an electronic control unit (12), a turning angle sensor (22), a torque sensor (5) and electric control wiring harnesses (11). The system makes full use of the advantage of the variable hydraulic transmission direction and achieves independent steering and accurate control of front wheels. When the control system breaks down, turning wheels can be directly controlled by steering wheel power through hydraulic path connection, and the system has a fault-tolerant function.
