Definitions
- the invention relates to a system consisting of a vehicle and a mobile device for unlocking the vehicle and/or enabling a function of the vehicle.
- a large number of vehicle and mobile device systems are already known in the prior art, whereby the vehicle can be unlocked by the mobile device or a function of the vehicle can be enabled or triggered by the mobile device.
- radio keys or cell phones for example, can serve as mobile devices.
- the fundamental problem here is that the necessary radio connection between the vehicle and the mobile device means that the mobile device requires a relatively high amount of energy, so that its battery has to be designed to be large or it empties comparatively quickly. As a result, mobile devices are subject to certain restrictions and must be correspondingly large.
- fob a comparatively small key fob (fob), which takes over the function of such a mobile device 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 system consisting of a vehicle and a mobile device for unlocking the vehicle and/or enabling a function of the vehicle with the lowest possible energy requirement on the part of the mobile device.
- a system consisting of a vehicle and a mobile device for unlocking the vehicle and/or enabling a function of the vehicle.
- the release of a function of the vehicle can also be understood as triggering a function of the vehicle.
- the vehicle has at least one first transceiver, which is designed in particular to send and receive data wirelessly, ie by radio.
- the mobile device has at least one second transceiver, which is designed in particular to send and receive data wirelessly, ie by radio.
- the first transceiver and the second transceiver are designed to establish a wireless connection with one another as connection partners that enables data exchange.
- the mobile device searches for its connection partner and serves as a master or control center (scanning or scanning role) and the vehicle signals its availability accordingly (advertising or advertising role).
- this requires a comparatively large amount of energy applied by the mobile device.
- the first transceiver ie the vehicle
- the second transceiver ie the mobile device
- the second transceiver is designed to signal its availability as a connection partner (advertising). This preferably only applies until the connection is established, as neither scanning nor advertising is then necessary.
- a battery can be provided to power the second transceiver in the mobile device and thus the entire mobile device with a correspondingly reduced space requirement.
- the transceiver or the two transceivers do not have to be limited to a specific radio protocol.
- the first transceiver and the second transceiver can each be NFC and/or BLE and/or UWB transceivers.
- the second transceiver is designed to send advertiser events on at least one advertiser channel
- the first transceiver is designed to check at least one advertiser channel for advertiser events and upon receipt of an advertiser event, establish a connection with the second transceiver sending the advertiser event.
- the mobile device can be, for example, a vehicle key or a key fob (fob) or a mobile phone. Since a key fob unlocks the vehicle or Can enable or trigger functions of the vehicle, can also be referred to as a so-called “smart fob”.
- the first transceiver i.e. the vehicle
- the first transceiver can have at least one outdoor unit for sending and receiving data on the exterior of the vehicle and an indoor unit for sending and receiving data in the interior of the vehicle.
- the first transceiver can therefore have two subunits, each of which can be designed to establish a connection with the first transceiver.
- the first transceiver can also have only two antennas, of which a first antenna is arranged in the interior of the vehicle (interior) and a second antenna is arranged on the outside of the vehicle (exterior).
- the first transceiver is preferably designed to determine which of the two antennas the second transceiver is connected to the first transceiver.
- the second transceiver ie the mobile device or an evaluation unit of the mobile device connected to it, is designed, a distance of the second transceiver from the first transceiver and/or a relative position of the second transceiver to the first transceiver and/or the Vehicle, which can be realized, for example, by evaluating the signal strength and / or by a connection to the outdoor unit or the indoor unit of the vehicle.
- the evaluation unit is designed to switch between different transmission protocols and/or between different intervals in which signals are transmitted between the connection partners, depending on the distance and/or the position of the transceivers relative to one another.
- the second transceiver transmits a signal via BLE every 0.3 seconds outside the vehicle and every 2 seconds inside the vehicle.
- a signal can be transmitted every 0.3 seconds if the transceiver distance is less than 10 m and every 0.9 seconds if the distance is greater than 10 m.
- the vehicle When transmitting via NFC, the vehicle can provide energy via the radio signal, so that the mobile device does not have to use any energy for this.
- an advantageous further development also provides that the system also a second mobile device with a third transceiver, wherein the third transceiver is designed to wirelessly send and receive data.
- the first transceiver and the third transceiver are designed to establish a connection with each other as connection partners that enables data exchange, the third transceiver being designed to check its environment for available connection partners, and the first transceiver being designed to check its availability as To signal connection partners.
- both a mobile phone can be used in the scanning role and a smart fob in the advertising role, which can independently connect to the vehicle, which or its transceiver supports both scanning and advertising.
- the third transceiver can also be an NFC and/or BLE and/or UWB transceiver.
- the first transceiver or the vehicle is preferably designed to simultaneously check the environment of the vehicle for available connection partners and to signal its availability as a connection partner, or alternately to check the environment of the vehicle for available connection partners and its availability as a connection partner to signal. This means that scanning and advertising are carried out alternately or simultaneously.
- the first transceiver can be designed to process the data received from the first and second mobile devices, to process data received by the second transceiver and data received by the third transceiver simultaneously or according to a prioritization transmitted by the data or predetermined by the associated transceiver.
- the first mobile device can also have a motion sensor, which switches the mobile device from an operating mode to a sleep mode after a predetermined period of inactivity without detected movement and only switches it back from the sleep mode to the operating mode when movement occurs again.
- a further aspect of the invention relates to a mobile device, which is designed in particular as a smart fob and can correspond to the first mobile device of the system.
- the mobile device is characterized in particular by the fact that it is designed to take on the advertising role itself and the second transceiver is correspondingly designed to signal its availability as a connection partner
- Fig. 1 is a schematic view of the system.
- the mobile device takes on the scanning role and the vehicle takes on the advertising role for establishing the connection.
- a smartfob is to be provided as a mobile device instead of, for example, a mobile phone, it is not possible to transfer the scanning role to the smartfob in a meaningful way due to the high power consumption, as the high power consumption leads to a battery that requires a lot of installation space or a short battery life.
- FIG. 1 a variant according to the invention is shown as an example and schematically, in which the system 1 is formed from vehicle 2 and a first mobile device 3.
- the vehicle 2 and the (first) mobile device 3 each have a transceiver A, B, whereby the first transceiver A of the vehicle 2 is designed to take on the scanning role and the second transceiver B of the smart fob or the first mobile device 3 is designed is to take on the advertising role and thereby establish a BLE connection 11 with each other.
- the first transceiver A can also be designed to take on the advertising role at the same time.
- the first transceiver A can have a scanning unit 21 and an advertising unit 22, which can each connect to a corresponding mobile device 3, 4.
- the system 1 can include a further or second mobile device 4, such as a mobile phone, which provides a third transceiver C, which is designed to take on the scanning role.
- the vehicle or the first transceiver A thereby supports scanning and advertising in parallel, with the first transceiver A either alternating between the roles or supporting them at the same time.
- Both functions are necessary in order to be able to use both the smart fob (first mobile device 3) and the mobile phone (second mobile device 4), but to minimize the power consumption of the smart fob (first mobile device 3).
- the first mobile device 3 can have an evaluation unit 31, which can evaluate the signal strength or the transmitted signal and thereby determine the positioning relative to the vehicle 2 and/or a distance from the vehicle 2. Based on the distance and/or positioning, different transmission protocols and/or transmission intervals can then be used in order to further minimize the energy requirement in the first mobile device 3.
