Abstract
An intervehicle distance control system for automotive vehicles is provided which includes a laser scanning type distance sensor for scanning a laser beam in a width-wise direction of a system vehicle to determine relative positions and relative angles of objects within a forward detectable zone and determines same lane probabilities that the objects exist in the same lane of a road as the system vehicle using a variable probability distribution based on the relative positions and the relative angles of the objects. A target preceding vehicle is then selected from the objects based on the same lane probabilities for controlling the speed of the system vehicle to maintain a distance to the target preceding vehicle constant.
