Abstract:
A running control system for an automobile comprising,a nearby object detector which detects a plurality of objects ahead of the automobile and for calculating a distance between the automobile and the objects nearby together with a ground velocity of the nearby objects; a velocity detector which detects a velocity of the automobile; and a velocity controller which automatically controls the velocity of the automobile; wherein said velocity controller comprises a slow cruising mode and a fast cruising mode, and performs velocity control of the automobile through switching the cruising mode according to the velocity of the automobile into said slow cruising mode which is activated when the velocity of the automobile is lower than a predetermined value, or into said fast cruising mode which is activated when the velocity of the automobile is higher than a predetermined value, such that in said slow cruising mode a preset constant distance is maintained between the automobile and a first object selected from the plurality of objects detected by said nearby object detecting means, and in said fast cruising mode a constant distance is maintained between the automobile and a second object selected from the plurality of objects which second object has a ground velocity more than a preset ground velocity value.
