PROBLEM TO BE SOLVED: To accurately decide the probability that a preceding vehicle is on the traveling lane of a driver's own vehicle by reflecting the judgement and intention of a driver, and to accurately decide and properly control the proximity level. SOLUTION: When a preceding vehicle is detected (S20), the driver's own vehicle lane is confirmed (S20), the proximity quantity Doi of a preceding vehicle 104 in driver's own lane 102 is calculated (S30), and the change quantityΔDoi of the proximity quantity Doi per unit time is calculated (S40). When a predetermined time t1 has not passed from the time the acceleration pedal is released by a driver (S50), coefficients K1 and K2 are set higher than standard values K1b and K2b (S70, 80), and probability Ri that the preceding vehicle is on the driver's own vehicle lane is calculated as the linear sum of the product of the proximity quantity Doi of the preceding vehicle to the the driver's own vehicle lane and the coefficient K1 and the product of the change quantityΔDoi of the proximity quantity and the coefficient K2 (S90), and the vehicle whose probability Ri is the highest is set as the preceding vehicle whose proximity level is to be judged (S100).
