STEERING CONTROL DEVICE FOR VEHICLES

Title:

STEERING CONTROL DEVICE FOR VEHICLES

Document Type and Number:

WIPO Patent Application WO/2006/101005

Kind Code:

A1

Abstract:

Provided is a vehicular steering control device for suppressing an overshoot or a phase delay of a vehicular position with respect to a target position, when an actuator of a steering mechanism is controlled so that the deviation of the vehicular position from the reference position of a running line may be reduced by an integral control. An FB control unit (60) for calculating a corrected steering assist torque (Tb) of a motor so as to reduce a positional deviation (Yd) and an angular deviation (Ah) comprises an integral element decision unit (64) for deciding an integral gain (Ki), which is to be multiplied by the positional deviation (Yd) in an integral gain operation unit (62), in accordance with the positional deviation (Yd), and for deciding a limit value (Icnt&lowbar lmt) of an integral control quantity (Icnt) in accordance with the positional deviation (Yd), and an integral control quantity limit unit (63) for limiting the integral control quantity (Icnt) within a range set by the limit value (Icnt&lowbar lmt), and for outputting the coming integral control quantity (Icnt&lowbar rel).
