PROBLEM TO BE SOLVED: To detect a preceding vehicle highly accurately according to various road conditions by appropriately changing the center of the scanning width of a scanning laser radar with optimum timing. SOLUTION: On the basis of the rate of change of a road curvature or the like ahead of an own vehicle, a target spot in which the center of the scanning width of the scanning laser radar 1 requires to be changed and the amount of target change required on the target spot are calculated. On the basis of the movable speed of an actuator 2, operation necessary time required for changing the center of the scanning width of the scanning laser radar 1 by the amount of target change is calculated. On the basis of the traveling speed of the own vehicle, an accumulated traveling distance traveled by the own vehicle during the operation necessary time is calculated. When the own vehicle reaches a spot within the accumulated traveling distance of the target spot, the operation of the actuator 2 is allowed to start. COPYRIGHT: (C)2005,JPO&NCIPI |
