Definitions
- the invention relates to a method for recognizing a vehicle key.
- the invention also relates to a computer-readable medium for recognizing a vehicle key, a system for recognizing a vehicle key, and a vehicle comprising the system for recognizing a vehicle key.
- Vehicle access systems are often contactless.
- a driver of the vehicle wears a transmitter, for example a key, a chip card or a smartphone, on his body with which contactless access to vehicles is possible. If the transmitter is within the reception range of an antenna in the vehicle, the vehicle can be unlocked.
- the range of one or more antennas in the vehicle is often technically limited in order to achieve high coverage. This can lead to the vehicle only being unlocked when there is a short distance between the transmitter and antenna.
- an object of the invention to detect a vehicle key from a greater distance between a transmitter of a contactless vehicle entry and an antenna of a vehicle.
- an object of the invention is to carry out a vehicle function more conveniently.
- the invention is distinguished by a method for recognizing a vehicle key.
- the method can be a computer-implemented method and/or a controller-implemented method.
- the vehicle key can be a conventional vehicle key, a chip card with an integrated, digital vehicle key, or a smartphone with an integrated, digital vehicle key.
- the method includes recognizing a person by a camera of the vehicle.
- the camera can be a driver assistance camera of the vehicle, for example.
- the vehicle can be an automobile.
- the method further includes detecting a position and a movement direction of the identified person by the camera of the vehicle, determining an antenna of the vehicle depending on the movement direction of the identified person, and increasing a maximum transmission power of the identified antenna of the vehicle in the direction of the position of the identified person.
- the maximum transmission power can be radiated conically through the determined antenna in the direction of the identified person.
- the method includes recognizing a vehicle key or a mobile terminal device comprising a digital vehicle key of the person using the increased, maximum transmission power of the vehicle's antenna.
- a transmission power of an antenna of a vehicle can be camera-based controlled in order to recognize a vehicle key from a greater distance.
- a vehicle function can be efficiently performed from a greater distance from the vehicle. This can efficiently increase convenience when approaching the vehicle and/or convenience when entering the vehicle.
- the method can further include executing a vehicle function after the vehicle key or the mobile terminal device has been recognized, including the person's digital vehicle key, using the increased, maximum transmission power of the vehicle's antenna, with the vehicle function preferably only being executed if the direction of movement of the person points towards the vehicle.
- the vehicle function preferably only being executed if the direction of movement of the person points towards the vehicle.
- the maximum transmission power of the determined antenna of the vehicle can be temporarily increased in the direction of the position of the person and/or in the direction of the movement of the person. This allows the range of the antenna to be efficiently increased.
- the maximum transmission power of the antenna can be temporarily increased depending on the distance from the person, and/or the transmission power of other antennas in the vehicle can be temporarily reduced depending on the distance from the person, so that a predetermined total , maximum transmission power of all antennas of the vehicle is reached.
- the Range of the antenna can be increased efficiently while at the same time a specification regarding a total maximum transmission power of all antennas of the vehicle are met.
- a total transmission power of all antennas belonging to a vehicle access system can be temporarily aligned in the direction of the person. This allows the detection range of the vehicle's antennas to be increased efficiently.
- the method can also include executing a key exchange protocol with the vehicle key or the mobile device comprising the digital vehicle key using the increased, maximum transmission power of the antenna to authenticate the vehicle key or the mobile device comprising the digital vehicle key.
- the person can be recognized by the camera of the vehicle when the camera is in a parking space monitoring mode, and the camera's parking space monitoring mode can continuously monitor a close vicinity of the vehicle while the vehicle is parked. This allows a person to be efficiently detected in the immediate vicinity of the vehicle and the vehicle's antennas to be adapted to the person detected.
- the invention is characterized by a computer-readable medium for recognizing a vehicle key, the computer-readable medium comprising instructions which, when executed on a computer or a control unit, execute the method described above.
- the invention is distinguished by a system for recognizing a vehicle key, the system being designed to carry out the method described above. According to a further aspect, the invention is distinguished by a vehicle comprising the system described above for recognizing a vehicle key.
- 1 shows an exemplary method for recognizing a vehicle key
- FIG. 2 shows an exemplary system for recognizing a vehicle key.
- the method 100 can detect a person through a camera of the vehicle 102.
- the method can also detect a position and a direction of movement of the detected person through the camera of the vehicle 104 parked vehicle is active.
- the parking attendant mode of the driver assistance camera can monitor surroundings of the parked vehicle in order to detect a person in the field of view of the driver assistance camera.
- the driver assistance camera can authenticate the person recognized in the field of view of the driver assistance camera.
- the method 100 can determine an antenna of the vehicle depending on the direction of movement of the identified person 106.
- the method 100 can also increase a maximum transmission power of the determined antenna of the vehicle in the direction of the position of the identified person 108.
- the maximum transmission power can in the direction of the identified person be temporarily increased.
- a total transmission power of all antennas of the vehicle can be temporarily aligned in the direction of movement of the identified person.
- a sensitivity of the antenna of the Vehicle can be increased based on the vehicle key.
- a reception range of the antenna of the vehicle can be aligned to the identified person.
- the method can further recognize a vehicle key of the person using the increased, maximum transmission power of the vehicle's antenna 110. If the method 100 recognizes the vehicle key, the method 100 can perform a welcome staging of the vehicle and/or vehicle access by unlocking and/or opening one or more doors and/or one or more flaps of the vehicle.
- FIG. 2 shows an exemplary system 200 for recognizing a vehicle key in a vehicle 202.
- the vehicle 202 comprises four cameras. Each camera can capture and monitor a predetermined area 204,206,208,210. A person 212 may be detected by the vehicle's camera upon entering the area 204 . Furthermore, the camera can determine a position and/or a direction of movement of the person 212 within the area 204 . Area 216 indicates a maximum transmission power of an antenna of the vehicle, which is aligned conically in the direction of identified person 212 .
- a key that the identified person 212 is carrying can be identified early by the vehicle and one or more vehicle functions can be performed.
- the key of the vehicle can be recognized earlier by increasing the transmission power of an antenna of the vehicle.
- the comfort for the recognized person can be efficiently increased by, for example, a welcome presentation, vehicle access and/or opening of the vehicle's doors being able to be carried out from a greater distance, specified by the detection range of the vehicle's cameras.
