Patent ID: 7100726

Claim:
An apparatus for controlling distance to another vehicle from a first vehicle, comprising: a vehicle running state detection unit for detecting a running state of the first vehicle; a first vehicular distance detection unit for detecting a first distance to a forwardly preceding vehicle, the first vehicular distance detection unit being mounted in a front center of the first vehicle; a second vehicular distance detection unit for detecting a second distance to the forwardly preceding vehicle, the second distance being detected with respect to positions having a center in line with the front center of the first vehicle; third and fourth vehicular distance detection units, respectively disposed at left and right front corners of the first vehicle, that detect third and fourth distances to a laterally preceding vehicle, the third and fourth distances being detected in a laterally biased forward direction of the first vehicle; a vehicular distance controller that determines existence of the forwardly preceding vehicle based on the first distance and the second distance; that determines existence of the laterally preceding vehicle based on the third distance or the fourth distance; and that controls the running state of the first vehicle based on the existence of the forwardly preceding vehicle or the laterally preceding vehicle; and a distance controlling actuator unit for controlling distance to the forwardly preceding vehicle or the laterally preceding vehicle by adjusting the running state of the first vehicle under control of the vehicular distance controller; wherein the distance controlling actuator unit controls the distance to the laterally preceding vehicle when the third or the fourth distance is smaller than the first distance, the second distance, and a predetermined distance.
