ABSTRACT:
Automotive vehicle control apparatus including a running stability control device for reducing engine output and/or applying brake to vehicle wheels for improving vehicle running stability, a shift control device for shifting an automatic transmission by engagement of at least one hydraulically operated frictional coupling device, depending upon a detected vehicle running condition as compared with a predetermined shift boundary pattern, a running stability control detecting device for detecting an operation of said running stability control device, and one of (a) a coupling pressure control device for controlling a hydraulic pressure of the frictional coupling device to be engaged to shift the automatic transmission, such that a rate of rise of the hydraulic pressure is lower when the operation of running stability control device is detected by the running stability control detecting device, than when the operation of the running stability control device is not detected, and (b) a shift point changing device for changing a shift point determined by the shift boundary pattern, when the operation of the running stability control device is detected.
