Abstract
A device for detecting objects in the blind spot on a side of vehicle includes a ranging main sensor, an auxiliary sensor, a comparison unit, and an output unit for outputting a warning signal which indicates objects in the blind spot. The detection range of the main sensor extends in the rear area of the vehicle and toward the respective vehicle side. The auxiliary sensor has a detection range which extends angularly offset to the detection range of the main sensor in the rear area of the vehicle. The comparison unit ascertains whether the detected object is a following vehicle on the basis of predefined correlations between the detection signals of the main sensor and the auxiliary sensor, and the detection unit blocks the output unit from outputting a warning signal when a following vehicle is recognized.
