<p><P>PROBLEM TO BE SOLVED: To provide a control device for steering rear wheels so that a vehicle stably travels, when steering front wheels in the inverse direction of the turning direction, when an active front steer device provided in the vehicle turns. <P>SOLUTION: This rear wheel steering control device has state quantity detecting means 13-16 and 19 for detecting a motion state quantity of the vehicle including a yaw rate, and a rear toe angle control means 120 for changing a toe angle of the right-left rear wheels of the vehicle by driving of an actuator in response to an indicating toe angle by calculating the indicating toe angleθTD based on the detected motion state quantity, and is constituted so that the active front steer device 18 performs counter steer control, and outputs a counter steer signal to a rear toe angle control means, when a basic front wheel steering angle 14 based on a steering quantity of a driver does not coincide with a target front wheel steering angle 19 based on the motion state quantity of the vehicle, and the rear wheel toe angle control means amplifies k1 gain of a yaw rate, and reduces k2 preset gain of the indicating toe angle, when a counter steer is inputted. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
