1. Vehicle door handle including a sensor assembly for detecting an operation request, wherein the vehicle door handle is formed as a fixed door handle for actuating an electric lock (e-latch),wherein the door handle is shaped in such a manner that a user in order to actuate it reaches behind the door handle into an open space between the door handle and the vehicle door, wherein a side of the door handle that is directed towards the vehicle is referred to as the inner side of the door handle and a side of the door handle that is facing away from the vehicle is referred to as the outer side,wherein the door handle comprises an electronic control and evaluation device, which generates control signals for the electric door lock in dependence on signals from the sensor assembly,whereinthe sensor assembly has at least one first capacitive sensor that is arranged in the door handle, whereby the at least one capacitive sensor is oriented towards the inner side of the door handle, and monitors a first handle section which is to be reached behind and grasped when actuating the handle, wherein the sensor assembly comprises at least a second and a third sensor which are arranged along the axial extension of the handle in an offset manner in relation to the capacitive sensor in the door handle,wherein the at least one second sensor is oriented towards the outer side of the door handle, and monitors a touching of the door handle from the outer side in a second handle section, andwherein the at least one third sensor is oriented towards the inner side of the door handle, and monitors a touching from the inner side in the second handle section,wherein the sensor assembly is connected to the electronic control and evaluation device and wherein the electronic control and evaluation device generates an opening signal, when the capacitive sensor detects a reaching behind and grasping of the door handle, and at the same time the at least one second sensor and the at least one third sensor simultaneously each detect a touching.
