Abstract

A vehicle door handle includes a sensor assembly for detecting an operation request. The door handle is fixed and actuates an electric lock. The sensor assembly includes a first capacitive sensor arranged in the door handle and oriented towards an inner side of the handle. It monitors a first handle section gripped when actuating the handle. Second and third sensors are arranged along an axial extension of the handle. The second sensor is oriented towards an outer side of the handle and monitors a touching from the outer side in a second handle section. The third sensor is oriented towards the inner side of the handle and monitors a touching from the inner side. The electronic control and evaluation device generates an opening signal when both the capacitive sensor detects a gripping of the door handle and the second sensor and the third sensor simultaneously each detect a touching.
