Abstract:
A follow-up cruise control apparatus comprising:a vehicle-to-vehicle distance sensor for detecting a relative distance of own vehicle to each of front obstacles including a plurality of vehicles present ahead of own vehicle;a speed sensor for detecting a speed of own vehicle;traveling direction target acceleration and deceleration calculating means for calculating traveling direction target acceleration and deceleration to optimize a distance to the front obstacle, based on, at least, the own vehicle speed and the relative distance to the front obstacle;safe acceleration and deceleration calculating means for calculating safe acceleration and deceleration indicating the degree of risk of collision with the front obstacle, based on at least the traveling direction acceleration and deceleration;means for applying the traveling direction target acceleration and deceleration calculating means and the safe acceleration and deceleration calculating means to each of the plurality of front obstacles, detected by the vehicle-to-vehicle distance sensor;front obstacle selecting means for selecting a front obstacle having a safe acceleration and deceleration with the highest degree of risk of collision, from among the plurality of the front obstacles; andvehicle control means for controlling a driving power or a braking power of own vehicle, based on, at least, the safe acceleration and deceleration or the traveling direction target acceleration and deceleration, to the front obstacle selected by the front obstacle selecting means.
