摘要： A vehicle control system for controlling its own vehicle to follow another vehicle in pursuit has a radar unit. The radar unit has function for detecting a relative distance from its own vehicle to a front vehicle in front of its own vehicle and a relative speed of the front vehicle with respect to its own vehicle, and outputting information representing the relative distance and the relative speed. A lane change detector detects a lane change which is made by its own vehicle and outputs a lane change signal indicative of the lane change. A processor estimates a future lane or path for its own vehicle from the lane change signal from the lane change detector, unlocks a preceding vehicle which its own vehicle has followed, and determines a new preceding vehicle which its own vehicle is to lock on based on the estimated future lane or path and the information outputted by the radar unit.

摘要： A vehicular radar apparatus comprising a radar beam transmission device and a reception device, and a processing unit for detecting the position of a target object from transmission signals and reception signals. The processing unit has a preceding vehicle judgment circuit for judging if a vehicle travelling in front of a subject vehicle in the same direction is the same vehicle as previously detected or not, and a signal strength comparing device for comparing the signal strength of a current reception signal reflected from the preceding vehicle, with a signal strength of a reception signal reflected from the preceding vehicle a predetermined comparison reference time prior, to thereby calculate a change amount in signal strength. When the change amount calculated by the signal strength comparing device drops beyond a previously set threshold value and it is judged by the preceding vehicle judgment device that the preceding vehicle is the same vehicle, it is judged that the detection sensitivity of the radar apparatus has dropped.
