DEVICE AND METHOD FOR INTEGRATING VARIABLE STEERING CHANGE GEAR RATIO AND STABILIZATION STEERING INTERVENTION

摘要

PROBLEM TO BE SOLVED: To provide a method and device for integrating variable steering change gear ratio and stabilization steering intervention in an automobile.;SOLUTION: In a control method of the variable steering change gear ratio in the automobile, the steering change gear ratio is changed depending on the longitudinal speed of the automobile in a predetermined longitudinal speed region. When there is a driving operation 101 limited in travel stability connected to the change of the speed, and when the longitudinal speed of the vehicle exists in the predetermined longitudinal speed region, the steering change gear ratio is kept at an instantaneous value having existed at the keeping time of the steering change gear ratio.;COPYRIGHT: (C)2005,JPO&NCIPI
