Automatic driving system

An automatic driving system comprising:

• radar means for detecting an obstacle in front of one vehicle to generate an obstacle detecting signal;
• imaging means for imaging a road surface in front of said one vehicle to output a video signal;
• image processing means for generating a vehicle position signal indicative of a position of said one vehicle in a width direction of the road from an image represented by the video signal;
• a navigation unit for generating road data indicative of the coordinates of a road in front of a current position of said one vehicle;
• road-to-vehicle communications means for receiving automatic drive traffic information signal;
• vehicle-to-vehicle communications means for transmitting and receiving a vehicle-to-vehicle running information signal between said one vehicle and at least one different vehicle other than said one vehicle;
• running instructions generating means for generating a running instruction;
• running course setting means for setting a running course based on said obstacle detecting signal, said vehicle position signal, said road data, said automatic drive traffic information signal, said vehicle-to-vehicle running information signal, and said running instruction;
• and
• vehicle control means for controlling navigation of said one vehicle such that said one vehicle runs following a target running trajectory based on said set running course,
• wherein said vehicle-to-vehicle communications means transmits a running course signal indicative of said running course, and a running course setting position signal indicative of a running position of said one vehicle at the time said running course is set.
