PURPOSE:To enhance control stability by configurating a device in such a way that steered wheels are steered in accordance with the rotation of a steering hande, and the steering handle is enabled to produce such reactions as a steering reaction corresponding to the amount of the steered handle, a steering handle holding reaction, and the stability of the steering handle. CONSTITUTION:NO.1 controlled amount determining means 9 determines NO.1 controlled amount which increases as the detected steering force increases, based on the output from a steering force sensor 6. And NO.2 controlled amount determining means 10 determines NO.2 controlled amount which increases as the detected steering reaction increases, so as to rotate a steering shaft 3 to the direction of a reference position based on the output from a steering reaction sensor 7. And an output means 11 is allowed to a output a steering shaft rotation control signal which is synthesized from both NO.1 and NO.2 controlled amounts, to a steering shaft actuator 4. And a target steering amount determining means 12 is provided so as to determine the target steering amount which increases as the detected value increases, based on the output from a steering variation sensor 8 allowing a steering control means 5 to be controlled depending on the target steering amount through an output means 13. |
