PURPOSE:To make it possible to change the steering characteristic of a vehicle in accordance with the driver's favor, by enabling one of steering ratio characteristics for a steering ratio changing means to be selected by a selecting means. CONSTITUTION:A pulse motor 14 rotates a pinion 13 meshed with a rack 12 formed in a rear wheel actuating rod 11 so that rear wheels are steered. The drive motor 24 for the pulse motor 14 and a hydraulic pump 23 is controlled in operation in accordance with a control signal delivered from a controller 25 as a control section for a rear wheel steering mechanism 7. There is provided a characteristic selecting section for selecting one of steering ratio characteristics stored in a characteristic memory section in association with the change-over of a select switch 28 which is connected to the controller 25 through a relay, and therefore, in accordance with the thus selected steering characteristic, a desired steering angle is computed. |
