Abstract
To maintain a predetermined distance to each of obstacles ahead of own vehicle, a follow-up cruise control apparatus calculates traveling direction target acceleration and deceleration of own vehicle, and treats, as s safe acceleration and deceleration, the product of the traveling direction target acceleration and deceleration and a weight coefficient determined by a distance between the front obstacle and the center line of the course of own vehicle. The follow-up cruise control apparatus selects a front obstacle having a safe acceleration and deceleration with the highest degree of risk of collision, from among all front obstacles ahead of own vehicle. Based on the safe acceleration and deceleration of the front obstacle, the follow-up cruise control apparatus prevents own vehicle from dangerously closely approaching or colliding with the front obstacle by restricting the driving power of own vehicle typically determined by an acceleration operation by a driver or by amplifying the braking power of own vehicle typically determined by a braking operation by the driver.
