Abstract
A differential cooperative active steering system for a front-axle independent-drive vehicle with electric wheels includes a steering rack which is arranged between a first steering wheel and a second steering wheel, and is able to generate lateral displacement and pull the first and second steering wheels to steer; a planetary gear mechanism, including a first input end, a second input end and an output end; a steering angle coupling motor, connected to the first input end; and an input shaft of the steering wheel, connected to the second input end. The planetary gear mechanism can realize the coupling between an input steering angle of an input shaft of the steering wheel and an input steering angle of the steering angle coupling motor. In addition, a method for controlling the differential cooperative active steering system is provided.
