  • the door handle unit can also be used, for example, as an outside door handle of the vehicle and/or in the side area of the vehicle, e.g. B. on the doors and / or in the rear of the vehicle, z. B. on the tailgate arranged.

It can be provided that only the safety sensor units are connected directly and/or immediately to the control device of the vehicle. In this way z. B. the increased safety requirements, in particular according to ASIL and / or according to IEC61508 and / or according to ISO26262, for the safety sensor unit or for the detection of the actuation action can be implemented cost-effectively. Wise accordingly the other sensor units of the door handle unit, in particular the primary sensor unit, unlike the safety sensor unit, preferably only have an indirect and/or indirect connection to the control device for indirect and/or indirect evaluation by the control device.

  • the safety sensor unit performs an air humidity-insensitive and/or weather-insensitive (and thus essentially error-free) detection of the actuation action independently of external interference, such as high air humidity and/or rain and/or the like.
  • the primary sensor unit is particularly susceptible to interference from such external interference.
  • the primary sensor unit z. B. can be designed as a capacitive sensor, which detects a change in capacitance and therefore delivers erroneous signals even with small changes in capacitance (such as rain). Therefore, an evaluation of the door handle unit must be provided, which detects such errors and a corrected signal z. B.
  • the safety sensor unit is designed, for example, as a Hall sensor, and therefore reacts z. B. exclusively on the magnetic field strength of an external magnetic field.
  • the external interference normally does not affect the magnetic field in the area of the door handle unit, so that the evaluation device does not have to analyze and correct errors. As a result, the actuation action can be reliably detected at low cost.
  • the safety sensor unit monitors in particular a mechanical movement and/or an opening process of the door handle unit in order to detect the actuation action.

This activation is detected by the safety sensor unit.
  • the safety sensor unit can be used, for example, as a transmitter and/or receiver and/or magnetic field sensor and/or Hall sensor and/or electronic switch and/or electronic contact and/or reed contact and/or optocoupler and/or light barrier and/or acceleration sensor and/or as Sensor or control unit subject to ASIL and/or as a capacitive sensor and/or as a mechanical switch and/or as a continuous signal transmitter.
  • the continuous signal transmitter has no (ASIL-relevant) logic element and can be evaluated directly by the control device, in particular without an intermediate evaluation by the logic element.
  • the continuous signal transmitter in particular continuously outputs a signal in normal operation, independently of the detection.
  • the safety sensor unit preferably detects a change in a physical quantity, e.g. B.
  • the magnetic field by an operation and / or by opening the door handle unit. Due to the direct evaluation of the safety sensor unit or the detection signal of the safety sensor unit by the control device, an error and/or a failure of the safety sensor unit can be detected immediately and immediately. Furthermore, it can also be provided that an error and/or failure of the other sensor units of the door handle unit, in particular the primary sensor unit, is not immediately and/or immediately reported, but z. B. delayed or never (by the control device) are detectable. To increase safety, it is therefore provided that the control device also detects the detection signal, for example independently of the evaluation device of the door handle unit.
  • the safety sensor unit (possibly in contrast to the primary sensor unit) can detect directional information of the actuation action and evaluate it by the control device.

  • This positive and/or negative detection signal differs in particular from a (detection) signal and/or from information of the detection signal in the event of an error and/or failure of the safety sensor unit. It is thus possible for the control device to detect the actuation action and in particular also to monitor the safety sensor unit by evaluating the detection signal. The monitoring makes it possible to determine an error and/or a failure and/or another state of the safety sensor unit that deviates from normal operation.
  • the safety sensor unit can, for example, be integrated in the door handle unit in such a way that an electric current flows through it during normal operation.

  • the safety sensor unit also supplies a signal, for example, when no actuation action is carried out.
  • the magnetic field sensor always supplies a signal even with a constant magnetic field. This reduces costs and at the same time achieves redundancy to increase security.
  • the safety sensor unit supplies the detection signal at least as a continuous or multi-stage analog signal, and preferably as a measurement signal, with the measurement signal being in particular proportional to and/or dependent on a physical variable measured by the safety sensor unit .

  • a central evaluation can be carried out by the control device to detect the actuation action. This increases safety and reliability and reduces costs.
  • a primary detection and/or detection signal of the primary sensor unit is electronically evaluated and/or interpreted by an evaluation device of the door handle unit in such a way that an evaluated primary detection and/or detection signal dependent on the primary detection and/or detection signal is lower information content than the primary acquisition and / or detection signal, in particular a binary signal arises.
  • the detection signal can in particular be a multi-stage and/or analog signal, the detection signal being electronically evaluated by the control device in such a way that a single-stage or multi-stage detection signal is produced which is dependent on the detection signal.
