Patent ID: 7278505

Claim:
A control device for starting motion of an own mobile body, said control device comprising: a distance measuring part for measuring distance to a front going mobile body; a speed control part for controlling the speed of said own mobile body such that distance to said front going mobile body will be constant based on said measured distance measured by said distance measuring part; a stop control part for detecting stopping of said front going mobile body based on said measured distance measured by said distance measuring part and generating a stop control signal for said own mobile body based on the detecting of the stopping of said front going mobile body; a start control part for detecting a start of said front going mobile body based on said measured distance measured by said distance measuring part and generating a start control signal for said own mobile body based on the detecting of the start of said front going mobile body; and an image-taking device for taking a first group of images of the front of said own mobile body until immediately after said stop control part detects the stopping of said front going mobile body and a second group of images of the front of said own mobile body when said start control part detects the start of said front going mobile body, a first image being selected from said first group of images and a second image being selected from said second group of images; wherein said start control part serves to inhibit said start control signal by concluding that there is an object in front of said own mobile body if said first image and said second image do not match.
