<p>An ECU (5) calculates an expected course for a vehicle (1) from a yaw rate detected by a rotational angular speed sensor (3) and a vehicle speed detected by a vehicle speed sensor (2), and calculates the distance from a forward vehicle, the forward vehicle being detected by a physical object detection means (4) and identified by a forward vehicle identification means, and then makes a comparison with a determination distance for a proceeding vehicle set by a determination distance setting means. The determination distance is calculated from the relative speeds of the forward vehicle detected by the physical object detection sensor (4) and the vehicle (1), and a forward vehicle which moves away from the vehicle (1) at high speed can be excluded from determination as a proceeding vehicle, by setting the determination distance to be shorter in accordance with an increase in the relative speed from the vehicle (1).</p> |
