Information output method

The method involves triggering person detection after activation of an approximation module to detect person data of a person outside of a motor vehicle by an environmental sensor. The detected person data are compared with stored person data. Output of information by an output unit is triggered when the detected person data matches with the stored person data. The detected person data are detected by approximation sensors and/or camera systems and/or sending units. The activation of an approximation module is taken place by existence of a stop signal of the vehicle.
