Abstract
A method for actuating a closing element of a vehicle including optically detecting when an object approaches a point in an area; searching for a smart key which is authorized for the vehicle only if an approach of an object has already been detected; activating additional sensors only when the smart key is found; collecting information by the additional sensor; and actuating the closure element if the collected information meets at least one predetermined requirement.
Claims25
A method for the actuation of a closing element of a vehicle, the method comprising:
- optically detecting an approach of an object to a position in a region using a sensor module, wherein the sensor module includes an optical sensor that is only partially activated for the detection of the approach;
- searching for a radio key that is authorized for the vehicle only in response to the approach having been previously detected by the optical sensor;
- activating a further sensor of the sensor module only in response to the radio key having been found;
- detecting information by the activated further sensor;
- and
- actuating the closing element in response to the detected information meeting at least one predetermined condition.
A device for actuating a closing element of a vehicle, the device comprising:
- a controller;
- a radio antenna;
- and
- a sensor module including an optical sensor and a further sensor,
- wherein the optical sensor detects an approach of an object to a position in a region wherein the sensor module includes an optical sensor that is only partially activated for the detection of the approach, wherein, in response to the detecting of the object approach, the radio antenna and the controller search for a radio key that is authorized for the vehicle,
- wherein the controller activates the further sensor only in response to the radio key being found,
- wherein the further sensor and the controller detect information, and
- wherein the device actuates the closing element in response to the controller determining that the detected information meets at least one predetermined condition.
