CAPACITIVE SENSOR ARRAY AND METHOD FOR DETECTING ACTUATION GESTURES AT A MOTOR VEHICLE

摘要

A sensor array for detecting the approach and movement gestures of a user at a motor vehicle includes a capacitive sensor array and at least one control device that is coupled to the sensor array and detects a change in the capacitance of the sensor array. The sensor array includes at least two sensor electrode arrays which are arranged at spatially offset positions on the motor vehicle. The sensor electrodes are configured as elongate electrode arrays and are arranged with the same spatial orientation. The control and evaluation device is designed for cyclical activation and evaluation of the sensor electrodes with changeable, electrode-specific, different cycle rates.
