LEFT-RIGHT INDEPENDENT STEERING CONTROL SYSTEM AND METHOD THEREOF

摘要

The present disclosure relates to a left-right independent steering control system and a method thereof, particularly a left-right independent steering control system that controls the other steering system such that the steering angles of both wheels satisfy Ackerman condition, when the steering angle of a vehicle is not controlled in accordance with steering input from a driver due to a breakdown in any one of left wheel and right wheel steering systems of the vehicle, and a method thereof.

主权项

1. A left-right independent steering control system, comprising:
a steering control calculating unit that calculates steering control input for both wheels from steering input by a driver; wheel steering units that separately adjust steering angles of both wheels on the basis of the calculated information; a breakdown determining unit that determines whether the wheel steering unit for any one of both wheels breaks, by determining whether the steering angles of both wheels adjusted by the wheel steering units are the same as steering angles corresponding to the steering control input; and a breakdown management unit that adjusts the steering angle of the other wheel to satisfy Ackerman condition on the basis of the current steering angle information of one wheel when the breakdown determining unit determines that the wheel steering unit for the one wheel breaks.
