Abstract
The present invention discloses a drive-by-wire electro-hydraulic steering system based on a double-winding motor and a hybrid control method. The steering system includes a steering wheel (), a steering column assembly, a road sense assembly, an electro-hydraulic power-assisted module, a double-winding motor power-assisted module (), a steering control unit, an electromagnetic clutch (), a steering tie rod (), a steering trapezoid () and steering wheels (). The steering system can be switched among various steering work modes according to work conditions of a vehicle, meets steering requirements under various work conditions, uses a work mode that two sets of windings of the double-winding motor work at the same time, and has a motor winding redundancy function. When one set of windings fails, the other set of windings can drive the motor to provide power-assisted torque.
