PROBLEM TO BE SOLVED: To extraordinarily improve selection precision of a preceding vehicle based on an own-lane probability of each vehicle ahead of an own vehicle for minimizing selection error of the preceding vehicle. SOLUTION: In accordance with the position of a candidate vehicle for a preceding vehicle and the state of a driving road detected based on probing output ahead of an own car by a distance measuring radar unit 2 mounted on an own vehicle 1, a reference own lane probability for each candidate vehicle is detected. Using a photographed image ahead of the own vehicle by a camera 3 for photographing ahead mounted on the own vehicle 1, the range of each candidate vehicle is determined. Using a photographed image by a camera 4 for photographing a driver mounted on the own vehicle 1, a view point of the driver of the own vehicle 1 is detected. View point probability to each range is detected based on the number of view points in each of the ranges detected in specific time. Each reference own-lane probability is weighed for correction based on the view point probability for each range to determine the view point corrected own-lane probability of each candidate vehicle. The candidate vehicle with the biggest view point corrected own lane probability is detected as a preceding vehicle. COPYRIGHT: (C)2006,JPO&NCIPI
