Blind spot`s object detecting device, has comparison unit ascertaining, based on preset correlations between detection signals whether vehicle following host vehicle is present, and blocking output unit from outputting warning signal

摘要

The device has an auxiliary ranging sensor with a detection range that extends into rear area of a host vehicle and angularly offset based on a detection range of a main ranging sensor into rear area of the vehicle. A comparison unit (16) compares detection signals generated by the main and auxiliary sensors, where the unit ascertains, based on preset correlations between the detection signals, whether a vehicle following the host vehicle is present, and blocks an output unit from outputting a warning signal.
