PURPOSE:To secure such a car behavior as having a feeling of linkage in time of a sudden change in the desired value by limiting the maximum value of an auxiliary steering angle feedback desired value to the small value as large as the extent of car speed, and regarding the value limited by an increment area describing a logarithmic function curve at an area where the ratio of the maximum value to the desired value is more than the specified ratio, as the auxiliary steering angle feedback desired value. CONSTITUTION:An auxiliary steering angle feedback desired value calculating means (f) limits the maximum value of an auxiliary steering angle feedback desired value to be the large, the smaller in car speed. In addition, it is provided with a steering angle limiter f1 which regards the value limited by an increment area describing a logarithmic function curve at an area where the ratio of the maximum value to the desired value is more than the specified ratio. With this constitution, the auxiliary steering angle feedback desired value to be obtained by means of steering angle limiter processing turns to such a value as being smooth and linked up. |
