Abstract

The invention relates to an active return-to-middle control system used for a wheel-side electric drive independent suspension. The system comprises suspension units, electric wheel units, a bracket assembly, a frame, a steering mechanism and an active return-to-middle control device, wherein the bracket assembly is transversely installed at the front end of the frame, the suspension units are installed at the two ends of the bracket assembly in a bilateral symmetry mode, the electric wheel units are installed on the suspension units, the steering mechanism is installed on the frame, and the active return-to-middle control device controls the steering mechanism to drive the electric wheel units to achieve power-assisted steering or active return-to-middle control. The active return-to-middle control system can reasonably provide aligning torque needed by wheels, the return performance is improved, and 'road feeling' is good.

Description

technical field [0001] The invention belongs to the technical field of electric vehicle suspension-steering control, and in particular relates to an active centering control system for wheel-side electric drive independent suspension. Background technique [0002] In recent years, with the increasing emphasis on energy saving and environmental protection, electric vehicles have developed rapidly, and various driving forms of electric vehicles have emerged. At present, the wheel drive system represented by electric wheels has high power density and high transmission efficiency. , large available space, simple structure, and the torque of each drive wheel can be independently controlled, which has become a research hotspot. [0003] The wheel side drive system in the existing patented technology has a complex structure, because the wheel side drive unit will increase the moment of inertia of the steering system around the kingpin, which will affect the return characteristics o...
