ABSTRACT:
In an apparatus and method for controlling a yaw rate of an automotive vehicle, a correction of a steering angular sensor detected absolute value of a steering angular displacement of a steering wheel of the vehicle is made by means of a controller by a correction variable for an offset of the neutral steered point to a real neutral steered point by a correction using which the detected absolute value of the steering angular displacement corresponds to the real neutral steered point and indicates zero at the neutral steered point to derive a neutral point corrected steering angle, determination of a target yaw rate of the vehicle on the basis of the neutral point corrected steering angular displacement is made, and a motion of the vehicle as a yaw rate control is controlled so as to achieve the target yaw rate, a determination of whether a variation rate of the neutral point offset correction variable is equal to or above a predetermined variation rate during a predetermined control period is made, and a suppression of the yaw rate control is carried out while determining that the variation rate of the neutral point offset correction variable is equal to or above the predetermined variation rate. In a preferred embodiment, a reduction of the yaw rate is carried out to suppress the yaw rate control.
