Apparatus and Method for Actuating a Function of a Motor Vehicle and Motor Vehicle

Abstract

An apparatus and a method for actuating a function of a motor vehicle are provided. The apparatus has a first transmission/reception device arranged at a first location of the motor vehicle and designed to receive a functional signal for actuating a function of the motor vehicle from a functional device different from the motor vehicle and to transmit a first acknowledgement signal, a second transmission/reception device arranged at a second location of the motor vehicle and designed to receive the acknowledgement signal from the first transmission/reception device, a control device in communication with the first transmission/reception device and the second transmission/reception device and designed to measure a propagation time of the first acknowledgement signal from the first transmission/reception device to the second transmission/reception device, to compare same with a predetermined threshold value, and to actuate or disable the function based on the comparison.
