<p>PROBLEM TO BE SOLVED: To perform an accurate and proper collision evasion control by considering the traveling environment of a driver's own vehicle in a device for automatically steering a steering device so as to evade contact with a vehicle running on the opposite lane. SOLUTION: The traveling environment such as the lane number of a road, whether it is suburbs or a town, the bending degree of the road and the congestion degree of the road is judged by a traveling environment judgement means 6, a control change means M4 changes the collision evasion control by a steering control means M3 corresponding to the traveling environment and thus, the driver is prevented from receiving a sense of incongruity and the collision evasion control is prevented from interfering with a spontaneous collision evasion operation by the driver. To put it concretely, in a case that it is difficult to accurately judge collision possibility since the level of the traveling environment is high, the collision evasion control is made hardly performable or change is performed so as to delay the start timing of the collision evasion control and weaken the collision evasion control.</p> |
