Definitions
- the invention relates to a radio key for unlocking the vehicle and/or for enabling a function of the vehicle.
- a large number of different radio keys for unlocking or operating vehicles are already known in the prior art.
- a mobile phone for example, can serve as such a radio key.
- radio keys in the prior art are subject to certain restrictions and must be correspondingly large.
- fob a comparatively small key fob (fob), which takes on the function of such a radio key and can also be referred to as a smart fob.
- the invention is therefore based on the object of overcoming the aforementioned disadvantages and of providing a radio key for unlocking a vehicle and/or for enabling a function of the vehicle with the lowest possible energy requirement on the part of the mobile device.
- a radio key is therefore proposed for unlocking a vehicle and/or for releasing a function of the vehicle, whereby the release of a function is also understood to mean triggering a function of the vehicle.
- the radio key has a sensor for motion detection, an evaluation unit and a transceiver, the transceiver being designed to signal its availability as a connection partner and to wirelessly send data to a connection partner and/or to receive data from the connection partner.
- the transceiver takes on the advertising role by signaling its availability, which is usually not the case in the state of the art.
- a vehicle or a transceiver of a vehicle, with which the radio key can connect and which is accordingly a connection partner therefore preferably takes on the scanning role to establish the connection.
- the transceiver provides at least one operating mode and at least one sleep mode, in which the transceiver's energy requirement is lower is, than in the at least one operating mode.
- the evaluation unit is designed to switch the transceiver from the at least one operating mode to the at least one sleep mode if no movement is detected by the sensor within a predetermined interval, and to switch the transceiver from the at least one sleep mode to the at least one operating mode if a movement is detected by the sensor.
- the combination of an advertising role and switching off when there is no movement means that significant energy savings can be achieved compared to the state of the art, so that the battery of the radio key can be designed to be smaller or have a longer lifespan while remaining the same size.
- a small radio key or a smart fob can be provided as a radio key.
- the radio key also has an operable switching element to enable the function of the vehicle.
- the evaluation unit is further designed to switch the transceiver from the at least one sleep mode to the at least one operating mode when the switching element is actuated.
- the transceiver can have a first sleep mode and a second sleep mode, wherein the energy requirement of the transceiver in the first sleep mode is lower than in the at least one operating mode and in the second sleep mode is lower than in the first sleep mode.
- the evaluation unit is designed to switch the transceiver from the first sleep mode to the second sleep mode if no movement is detected by the sensor within a predetermined second interval.
- the transceiver is designed to disconnect a connection to the connection partner in the first sleep mode and to stop signaling availability as a connection partner.
- the transceiver is preferably designed to connect to the connection partner more quickly after switching from the first sleep mode to the operating mode than after switching from the second sleep mode to the operating mode.
- the transceiver can be an NFC and/or BLE and/or UWB transceiver.
- the transceiver is also designed to send advertiser events on at least one advertiser channel, at least until a connection is established, in order to thereby signal in particular the availability as a connection partner.
- the sensor can also be a motion sensor or an acceleration sensor.
- a further aspect of the invention relates to a method for saving energy on a radio key according to the invention.
- the transceiver is switched from the operating mode to the sleep mode by the evaluation unit if no movement is detected by the sensor within a predetermined interval. Furthermore, the transceiver is switched from sleep mode to operating mode when movement is detected by the sensor.
- the figure is a schematic example and represents a smart fob 1, which can be a radio key 1.
- the smart fob or radio key 1 has a sensor 10, a transceiver 30 and an evaluation unit 20.
- a switching element 40 that can be actuated by a user is also provided.
- Sensor 10, transceiver 30 and switching element 40 are each connected to the evaluation unit 20, so that the evaluation unit 20 can evaluate respective data or signals and at least control the transceiver.
- the radio key 1 has a battery 50, whereby an accumulator or an energy generator can also be provided instead and in addition.
- the battery 50 supplies power or energy-requiring components of the radio key 1 and can be particularly small due to the energy-saving design of the radio key 1, so that a small installation space and/or a long battery life is achieved.
- the transceiver 30 takes on the advertising role when establishing the connection, i.e. does not itself act as a master and leaves this role to its connection partner, ie in particular the vehicle.
- Four modes are stored in the evaluation unit 20 for the transceiver, into which it is switched depending on a movement detected by the sensor 10.
- first operating mode A a first operating mode A
- second operating mode B a (first) sleep mode C
- a deep sleep mode or second sleep mode D a first operating mode A
- first operating mode A a second operating mode B
- second operating mode C a (first) sleep mode C
- second sleep mode D a deep sleep mode or second sleep mode D.
- the transceiver 30 sends advertiser signals on at least one of, in particular, three advertiser channels.
- the radio key 1 exchanges data with its connection partner, i.e. the vehicle, via its transceiver 30.
- the sending of advertiser signals is stopped and a connection with the connection partner is terminated.
- the transceiver 30 is not switched off or at least not completely switched off, so that a change to the first operating mode A is possible quickly.
- the second sleep mode or the deep sleep mode D provides that, in addition to the first sleep mode C, the transceiver 30 is switched off, so that an initialization of the transceiver 30 is necessary before a change to the first operating mode A and the change to the first operating mode A takes longer as starting from the first sleep mode C.
- the respective operating mode A, B is changed to the first sleep mode C.
