Abstract
The invention relates to an access system (200) for a vehicle (3), in particular for activating an electric lock (2) of the vehicle (3), comprising: at least one actuation sensor (30), by means of which a first inductance detection (110) can be performed for the detection of an activation action, at least one information sensor (35), by means of which a second inductance detection (120) can be performed, so that an additional information on the activation action can be determined, whereby the detection of the activation action can be verified.
Claims26
An access system for a vehicle, comprising:
- at least one actuation sensor arranged inside a door handle body of a door handle, by means of which a first inductance detection for detecting an activation action can be performed,
- at least one information sensor, by means of which a second inductance detection can be performed, so that an additional information to the activation action can be determined,
- whereby the detection of the activation action can be checked for plausibility to determine a correctness of the detection of the activation action,
- wherein the information sensor is arranged on the vehicle in a location that is sufficiently spaced from the actuation sensor, such that an influence on the information sensor caused by the activation action is less than an influence on the information sensor caused by an external impact on the vehicle occurring independent of the activation action, such that an interference on the detection of the activation action can be detected by means of the second inductance detection.
A method for a vehicle, wherein at least one actuation sensor arranged in a door handle body of a door handle and at least one information sensor are provided,
- wherein the following steps are provided:
- a) detecting a deforming by means of a first inductance detection of the actuation sensor,
- b) detecting an activation action of an operator by means of a first evaluation of the first inductance detection,
- c) determining an additional information to the activation action by a second inductance detection of the information sensor,
- d) verifying the detection of the activation action by checking for plausibility to determine a correctness of the detection of the activation action;
- wherein the information sensor is arranged on the vehicle in a location that is sufficiently spaced from the actuation sensor, such that an influence on the information sensor caused by the activation action is less than an influence on the information sensor caused by an external impact on the vehicle occurring independent of the activation action, such that an interference on the detection of the activation action can be detected by means of the second inductance detection.
The method according to claim, 18
- wherein
- at least a temperature or a deforming or a vibration is determined by the second inductance detection.
