Handle module with actuating module for an electronic locking system, and vehicle door with handle module
A handle module may have at least one actuating module for triggering a switching function. The actuating module may be designed as a capacitive actuating sensor and may have two or more capacitive auxiliary electrodes for detecting secondary signals. The actuating module may also have a capacitive main electrode for detecting an actuation path. And, the actuating module may also have an electronic evaluation unit which is connected to the auxiliary electrodes and the main electrode. The evaluation unit may be configured to trigger or block a switching signal for the switching function as a function of the detected signals of the auxiliary electrodes and the detected signal of the main electrode.
1 . A handle module comprising at least one actuating module for triggering a switching function, wherein the actuating module is designed as a capacitive actuating sensor, and comprises:
two or more auxiliary electrodes for detecting secondary signals,
a stroke-sensing main electrode for detecting an actuation path, and
an electronic evaluation unit which is connected to the auxiliary electrodes and the stroke-sensing main electrode,
