摘要： A device for estimating side slide velocity of a vehicle, comprising: a means for detecting longitudinal velocity of the vehicle body; a means for detecting yaw rate of the vehicle body about its center of gravity; a means for detecting lateral acceleration of the vehicle body at the center of gravity; and a means for integrating on time basis difference between the lateral acceleration detected by the lateral acceleration detection means and product of the yaw rate detected by the yaw rate detection means and the longitudinal velocity detected by the longitudinal velocity detection means such that only high frequency components thereof are integrated to produce a side slide velocity signal. The device may further comprise a means for estimating slip angle of at least either the front wheels or the rear wheels and converting the estimated slip angle into side slide velocity of the vehicle body at its center of gravity to produce a side slide velocity signal; and a means for summing the side slide velocity signal produced by the integration means and the side slide velocity signal produced by the slip angle estimation and conversion means to produce a final side slide velocity signal.

摘要： An electric control apparatus (C) for a four-wheel steering system is designed to calculate a rear wheel steering angle on a basis of a control rule corresponding with a steering mode selected from a plurality of rear wheel steering modes thereby to steer a set of dirigible rear road wheels (RW1, RW2) at the calculated steering angle. The electric control apparatus (C) is further designed to calculate a difference between new and old steering angles calculated when the selected steering mode has been changed to another one of the steering modes and immediately after change of the selected steering mode, to gradually decreasing an absolute value of the calculated difference at a predetermined time interval, to correct the new steering angle in accordance with the absolute value of the calculated difference until the absolute value becomes zero after change of the selected steering mode and to control an actual steering angle of the rear road wheels (RW1, RW2) in accordance with the corrected new steering angle.
