Patent attributes
A detection ECU acquires the position of the preceding vehicle, based on image information captured by an imaging device, and generates the track of the preceding vehicle, based on the position of the preceding vehicle. The detection ECU then performs following travel control for following the preceding vehicle by calculating the amount of control for causing the own vehicle to travel along the track of the preceding vehicle, and by causing the own vehicle to travel, based on the calculated amount of control. During the following travel control, if the width of the preceding vehicle is narrower than a predetermined width, the detection ECU calculates the amount of control such that the curvature variation in the track of the own vehicle is smaller than in the case where the width of the preceding vehicle is not narrower than the predetermined width.
