A method for operating an environmental recognition system of a vehicle, in particular, a proximate region recognition or parking assistance system, comprising sensors for detecting objects proximate the vehicle, wherein, during operation of the system, an object located in the detecting area of the sensors is recognized and the separation and/or the position of the object relative to the vehicle are determined. When disturbing signals occur and are recognized, a change of the separation and/or the position of the vehicle relative to the object are determined by information detected by other vehicle systems. A system for operating such a method is also disclosed.
