The invention discloses a novel four-wheel steering mode for a four-wheel independent drive electric automobile. The steering mode combines a traditional front wheel steering system and a rear wheel differential steering system. The differential steering mode of the rear wheels is that the driving force difference is generated by controlling the different driving forces of the driving motors of the left and right wheels, so that the wheels are driven to rotate around the main pins to generate rear wheel steering angles, and the advantage of four-wheel steering is reflected. The four-wheel steering system can greatly improve the operation stability and the low-speed steering maneuverability of the vehicle during high-speed steering. A complex steering mechanism can be canceled by adopting rear wheel steering, the structure is simple, and the space utilization of the vehicle is improved. For the limit working condition, due to the fact that the aligning torque of the wheels is very small, the extremely small driving torque difference can generate the extremely large steering angle. The clutch device is installed at the steering tie rod of the rear wheel, the combination pressing degree can be automatically adjusted to generate friction torque for overcoming excessive driving torque difference, and therefore an expected rear wheel steering angle is obtained.
