Automatic driving system
An automatic driving system allows a vehicle to travel by automatic driving. The system includes first and second detectors and first and second determiners. The first detector is disposed on a movable part of the vehicle and detects an object located around the vehicle. The second detector is disposed on the vehicle and has an object detection region that partially overlaps a detection region of the first detector. The first determiner determines whether a detection state of the first detector based on a position of the object detected by the second detector and behavior of the object estimated from a detection position of the first detector and a traveling state of the vehicle. The automatic driving availability determiner determines availability of the automatic driving according to the detection state of the first detector and disables the automatic driving when the first detector is not in a regular detection state.
