If the sign of the relative speed of the non-fixed object is negative, the determination width for own lane is expanded in the lane-width direction. According to the expanded determination width for own lane, both the preceding vehicle on the adjacent lane and the preceding vehicle on the own lane are recognized as existing on the own lane. Therefore, if it is determined that the risk to collide with the preceding vehicle on the adjacent lane is high, the decelerating assist control is executed to prevent collision with this preceding vehicle. Also, if it is determined that the risk to collide with the preceding vehicle on the own lane is high, the decelerating assist control for preventing collision with this preceding vehicle is executed.
