PROBLEM TO BE SOLVED: To eliminate delay of control responsiveness even in the case when vehicle behavior suddenly changes by providing an output control quantity computing means to computer an output control quantity by totaling a vehicles behavior corresponding control quantity and a high-pass processing value. SOLUTION: Delay of each control response against steering input is corrected at the time of sudden change of vehicle behavior. High-pass processing is carried out to a sum tfd of targetΔN follow-up control quantity tb, tack-in corresponding control quantity td and accelerated turning control quantity te. Additionally, speed of output of a control signal is increased. However, steering transient responding control quantity tc does not make the high-pass processing. Output control quantity tf is provided by adding a signal which is not processed to a processed value processed by the high-pass processing. Finally, final output control quantity tad is computed by adding the steering transient response control quantity tc not processed by the high-pass processing to the output control quantity tf. A phase of each control item is advanced by high-pass- processing control delay against high frequency input by fast steering in this way.
