Abstract

The present invention relates to an active centering control system for wheel-side electrically driven independent suspension, the system includes a suspension unit, an electric wheel unit, a bracket assembly, a vehicle frame, a steering mechanism and an active centering control device; wherein, The bracket assembly is installed horizontally at the front end of the frame, the suspension unit is installed symmetrically at both ends of the bracket assembly, the electric wheel unit is installed on the suspension unit, the steering mechanism is installed on the frame, and the active return control device controls the steering The mechanism drives the electric wheel unit to realize power steering or active centering control. The active centering control system can reasonably provide the centering torque required by the wheels, improve the centering performance, and have a good "road feel".

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...
