Title:
TURNING CONTROL DEVICE FOR VEHICLE
Document Type and Number:
Japanese Patent JPH0558322
Kind Code:
A
Abstract:

PURPOSE: To prevent travelling stability from being lowered even if either one of both devices is broken down in a turning control system formed by combining an auxiliary steering device and an automatic brake device with each other.

CONSTITUTION: A control unit 7a controls a motor 5 so as to be kept at a rear wheel steering angle δr obtained according to input information , V and θ, and a control unit 7b controls left/right wheel cylinders 11L and 11R by means of fluid pressure control valves 13L and 13R so as to be kept under left/right brake fluid pressures PBL and PBR obtained from input information PL, PR and (g). However, when failure signals SSF and SBF are transmitted from either one both the control units 7a and 7b, a normal system control regulation is changed in the direction so as to increase travelling stability. Thereby, even when either one of these two devices fails, travelling hardly becomes unstable, so that travelling stability can be secured.
