1. An object sensing device for a driver assistance system in a motor vehicle, comprising:
- at least two sensor systems which measure data concerning at least one of a location status and a motion status of an object in a vicinity of the motor vehicle, detection regions of the sensor systems overlap one another; and
an error recognition arrangement configured to check the data for absence of contradictions and to output an error signal upon detection of a contradiction;
wherein the error recognition arrangement checks, on a basis of the data, whether the object is located in an overlap region between a first detection region of a first sensor system and a second detection region of a second sensor system, and outputs the error signal one of when the object is not located by the second sensor system and when data measured by the second sensor system, taking into account error limits, deviate from data measured by the first sensor system;
and wherein for objects that are located in the overlap region, the error recognition device weights the data measured by the first sensor system and the second sensor system in accordance with reliability, and combines the weighted mutually corresponding data into data that are output to the driver assistance system.

Abstract
An object sensing apparatus for driver assistance systems in motor vehicles, including at least two sensor systems which measure data concerning the location and/or motion status of objects in the vicinity of the vehicle, and whose detection regions overlap one another, characterized by an error recognition device that checks the data measured by the sensor systems for absence of contradictions, and outputs an error signal upon detection of a contradiction.
