Abstract

The invention provides a dual-motor wire-controlled complex steering system and a control method thereof. The dual-motor wire-controlled complex steering system comprises a steering wheel, a steeringcolumn assembly, a road sense assembly, a dual-motor steering execution device and a steering control unit, and steering control of the system is completed through an adaptive control method. According to the dual-motor wire-controlled complex steering system, integration and unification of steering performance such as larger steering torque, lower energy consumption, faster response speed can berealized, steering control parameters are adjusted automatically according to actual driving situation, uncertainty in driving environment can be better resisted, and steering accuracy and vehicle safety are ensured.

Description

technical field [0001] The invention belongs to the technical field of automobile steering systems, and specifically refers to a dual-motor wire-controlled compound steering system and a control method thereof. Background technique [0002] With the increasing intelligence of automobiles, the execution modules of automobiles also tend to be controlled by wire. Among them, the steer-by-wire system can freely design the transmission ratio, improve the active safety performance, save the layout space, and it is easier to cooperate with the brake-by-wire and throttle-by-wire, etc., which is a hot spot of current research. The implementation methods of the existing steering-by-wire systems mainly include the following categories: single-motor steering-by-wire, dual-motor steering-by-wire, and four-wheel steering. The single-motor wire-controlled steering has a simple structure, but the motor power used is relatively large; the dual-motor steering can use the other motor to steer...
