Abstract:
1. A device for detecting an object in a blind spot on a side of a host vehicle, comprising: a main ranging sensor having a detection range that extends into rear area of the host vehicle and towards a selected vehicle side; an output unit for outputting a warning signal which indicates an object in a blind spot on the selected vehicle side; an auxiliary ranging sensor having a detection range that extends into rear area of the host vehicle and angularly offset with respect to the detection range of the main ranging sensor into the rear area of the vehicle; and a comparison unit for comparing detection signals generated by the main ranging sensor and the auxiliary ranging sensor, wherein the comparison unit ascertains based on predefined correlations between the detection signals whether a vehicle following the host vehicle is present, and wherein the comparison unit blocks the output unit from outputting a warning signal when it is determined that a vehicle following the host vehicle is present; wherein the comparison unit blocks the output unit from outputting a warning signal if, within a predefined time period including multiple measuring cycles of the main ranging sensor and the auxiliary ranging sensor, the following condition is satisfied:
