PURPOSE:To improve steerability in a car ever so better, by operating a selecting device, which realizes a steering angle ratio corresponding to the information selected from plural numbers of preset steering angle ratio information, only at a time when a car speed variation is within the specified range. CONSTITUTION:The specified steering angle ratio information (d) is stored in a memory of a computer 31. This information (d) consists of plural steering angle ratio data k1, k2...kn. At a select switch 34, when optional buttons other than a pushbutton 35a, for example, a pushbutton 35 is pressed, the steering angle ratio data k1 is read out of the steering angle ratio information (d). This data k1 is compared with steering angle ratio data kb out of a position sensor 33 and both are made into an operation process (f) and thereby corrected information b2 is securable. At a selecting process (c), this corrected information b2 is outputted in a case other than AUTO, whereby a steering angle ratio in the rear wheel is set to the data k1 by way of an output unit 37. At this time, when a car speed variation signal based on a signal out of a car speed sensor 32 is larger than reference car speed variation data (g), the selecting process (c) regulates the output of the said corrected information b2. |
