PURPOSE:To prevent a driver from feeding physical disorder by providing a driving road surface condition detection means, and reducing auxiliary steering angle feedback operating amount when a driving road surface is judged as a rough road by the driving road surface condition detection means. CONSTITUTION:At the time of driving, a driving condition target amount computation means (b) computes the target of driving condition amount, based on a vehicle condition detected amount inputted from a vehicle condition detection means (a). An actual driving condition amount detection means (c) detects operating condition amount generated at a vehicle actually. An auxiliary steering angle feedback operating amount decision means (d) determines auxiliary steering angle feedback operating amount, based on a difference between the target of a driving condition amount and the detection amount of an actual driving condition amount. If a road surface is judged as a rough road by a driving road surface condition detection means (e), a driving steering angle feedback operating amount correction means (f) reduces an operating amount according to the degree of the rough road. When returning from the rough road to a good road, a driver is prevented from feeling physical disorder. |
