TRAILER WHEEL STEERING CONTROL METHOD AND ITS DEVICE

摘要

PROBLEM TO BE SOLVED: To improve the steering stability of a connected car and resistance to external disturbances, to simplify trailer wheel steering control and to improve its reliability. SOLUTION: A controller 105 for a trailer wheel steering control device calculates a target trailer wheel steering angle from trailer yawing rate data inputted from a yawing rate sensor 101 by using a transmission function indicating a relation between a trailer wheel steering angle and a trailer yawing rate and steers a trailer wheel 18 via a control valve 82 and a hydraulic cylinder device 30 such that an actual trailer wheel steering angle detected by a steering angle sensor 103 becomes equal to the target trailer wheel steering angle.
