PURPOSE:To prevent production of a feeling of physical disorder sensible to a drive by causing the change of a rear wheel steering angle in a steering keeping state along with the change of a car speed, in a rear wheel steering angle control device for controlling a rear wheel steering angle based on at least a front wheel steering angle and a car speed. CONSTITUTION:A fuzzy controller 50 which decides a target rear wheel steering angle by using fuzzy inference based on a front wheel steering angle, a car speed, a set mode (the mode of a steering feeling desired by a driver), and a steering speed detected by various sensors 30, 32, 34, and 60, respectively, is provided. A fuzzy rule is set such that a constant target rear wheel steering angle is decided regardless of a change in a car speed in a steering keeping state and a high speed running state. |
