Abstract: A method for detecting a function actuation on a motor vehicle with a sensor device includes monitoring the signals of a proximity sensor as to a first signal reply S1. The signals of the proximity sensor are monitored for a time period Ts wherein the method is interrupted when the signal reply changes by more than a value St within the period of time Ts. The signal device is actuated after time Ts has expired in order to signal to the user that the actuation of time has expired. The signals of the proximity sensor are monitored for time Te wherein the method is continued when the signal of the proximity sensor changes by more than a predetermined value Se within the period of time Te. Otherwise, the method is interrupted. If the method is continued, the actuation of the function of the motor vehicle is detected and the function trigger is signaled to a control device in the motor vehicle.

Abstract: A method for operating a function in a motor vehicle employs a sensor arrangement with at least two spaced sensors for detecting operations caused by a user. Signals of a first sensor are monitored until a first characteristic signal answer is detected. A user-carried identification device is queried to verify authorization to access the requested function. Signals of a second sensor are monitored to determine an operation caused by approaching the second sensor. Signals from the first and second sensors are monitored for a predetermined time period t1. If the signals indicate a continued operation of the two sensors during t1, an expiration of t1 is signaled to the user. Signals of the first sensor are monitored for a predetermined time period t2. If the signal of the first sensor indicates a cancellation of the operation within t2, the function of the motor vehicle is triggered.
