Abstract
A leading vehicle detecting apparatus judges whether or not a first vehicle is following a second vehicle. The apparatus includes a signal acquiring section, a storage section, and calculating section. The signal acquiring section acquires position signals outputted from a position detecting section that detects the position of the second vehicle, and detection signals outputted from a state detecting section that detects a state of a first vehicle cruising line. The storage section stores in advance a probability map showing the probability of the first vehicle following the second vehicle, based on a distance between an expected cruising line of the first vehicle and the position of the second vehicle. The calculating section calculates the expected cruising line based on the detection signals, and judges whether the first vehicle is following the second vehicle based on the expected cruising line, position signals, and probability map.
