DETECTION METHOD FOR OPERATING GESTURES

摘要

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.

1. A method for operating a function in a motor vehicle, including a sensor arrangement which has at least two spaced sensor devices for detecting the respective operations caused by the approach of a body part of a user, including the steps,
monitoring the signals of a first sensor device until a first characteristic signal answer s1 is detected by the first sensor device, a user-carried identification device is queried to verify authorization to access the requested function, querying of signals of a second sensor device and evaluating the associated signal answer s2 to determine an operation caused by approaching the second sensor device, if signal answer s2 indicates an operation caused by an approach towards the second sensor device, monitoring signals from the first and second sensor devices for a predetermined time duration t1, if the signals indicate a continued operation of the two sensor devices during time period t1, signaling the expiration of the duration t1 to the user, monitoring the signals of the first sensor unit for a predetermined time period t2, if the signal of the first sensor device indicates a cancellation of the operation within time period t2, triggering the function of the motor vehicle.
