Definitions
- the invention relates to a method for operating a radio system of a motor vehicle, a radio system for a motor vehicle and a motor vehicle with a radio system.
- radio systems can be used which are capable of receiving digitally broadcast radio programs.
- such radio systems have a receiving device in the form of a so-called DAB receiver, the abbreviation DAB standing for Digital Audio Broadcasting, which is a digital transmission standard for terrestrial reception of digital radio.
- DAB receiver the abbreviation DAB standing for Digital Audio Broadcasting, which is a digital transmission standard for terrestrial reception of digital radio.
- a transmitter overview shows which digital radio programs can currently be received on the vehicle side. In addition, it is usually shown whether the transmitter is currently being received or not currently being received.
- the receiving device will be notified accordingly beforehand the shading areas occurring in the future, in which certain radio stations can not be received.
- various radio stations are buffered in a memory.
- the motor vehicle passes through one of the shading areas in which no radio reception is possible, the previously buffered data is played back.
- DE 102012000885 A1 shows a method for setting radio stations in a motor vehicle radio system.
- a number of radio stations are displayed, which are broadcast along a route planned by a driver.
- DE 102012204090 A1 shows a radio receiver with an automatic response to radio reception interference. As soon as a motor vehicle passes through a tunnel in which a previously tuned radio station can no longer be received, it automatically switches to a radio station that can be received in the tunnel.
- a region surrounding the motor vehicle is specified. It is determined which digital radio stations within this area are receivable without interference by means of a receiving device of the radio system. Only those digital radio stations are displayed which can be received without interference within this area.
- the area surrounding the motor vehicle is NEN specified environment of the motor vehicle, which is moved while driving with the car corresponding to the speed of the motor vehicle with this. If, for example, the motor vehicle is arranged centrally in the predefined area, then it can be provided, for example, that when driving with the motor vehicle the area is always displaced in such a way that the positioning of the motor vehicle within the area always remains the same.
- the display of the digital radio stations does not take place depending on whether the relevant digital radio stations can currently be received, but rather on the basis of a geographical evaluation.
- the current location of the motor vehicle is assessed as to whether a digital radio reception of corresponding digital radio stations will be possible around this location within the given area, ie in a closer environment of the motor vehicle. Only those digital radio stations are actually displayed, for example within a selection menu, which can also be received without interference within this area. This can ensure that a vehicle occupant can even select only those digital radio stations at all, which he can also receive interference-free and reliable, for example, in the next few minutes. Vehicle occupants of the motor vehicle are thus not affected by a constant back and forth between a functioning digital radio reception and a mute.
- a file in particular a digital receiving card, is provided in which is deposited, which digital radio stations are location-sensitive interference-free, using this file is determined which digital radio station in the given Area are receivable trouble-free.
- This file can for example be stored on the vehicle side within a memory device.
- an online access is made to this file, which is stored on a vehicle-external server device.
- a wireless connection between the vehicle-external server device and the radio system of the motor vehicle is made, so that the file in question can be accessed.
- this file is stored on the vehicle side.
- an update of the file in predetermined NEN time intervals for example by a wireless connection between the vehicle-external server device and the radio system is made so that an update of the file can be done.
- the updating of this file has the particular advantage that, for example, weather-dependent changes with respect to the digital radio reception or, for example, a change in a distribution of transmitting stations which radiate digital radio stations can be taken into account.
- a further advantageous embodiment of the invention provides that the file is updated at predetermined intervals based on data provided by other motor vehicles with respect to a location-dependent reception quality of the digital radio stations.
- the cars may, for example, detect respective digital reception qualities with respect to respective digital radio stations and wirelessly transmit to an off-board server device.
- the file already mentioned above is also stored, which is updated based on the data transmitted by the respective cars with regard to the reception quality of the digital radio station.
- the file can then be continuously updated by establishing a wireless connection between the off-board server device and the radio system.
- the size of the area is set the greater the faster the motor vehicle drives. For example, if the car moves on a country road at 80 to 100 km / h, the area is made smaller in size, especially in the direction of travel of the motor vehicle, as if the car should drive at 130 to 150 km / h, for example. In this way it can be ensured that, depending on the speed, it is always possible to determine in advance for a corresponding period of time which digital radio stations will still be receivable in the future while driving with the motor vehicle. In a further advantageous embodiment of the invention, it is provided that if a navigation route of the motor vehicle is predetermined, the area is specified such that the area comprises at least part of the navigation route.
- a further advantageous embodiment of the invention provides that if no navigation route of the motor vehicle is specified, time-dependent and / or depending on the day of the week, ie depending on whether it is a weekday, a holiday or the like, and taking into account so far A route traveled with the motor vehicle is determined as an expected route and the area is predefined such that the area comprises at least part of the route.
- a direction of travel of the motor vehicle is determined taking into account the time of day and the respective day of the week and taking into account the routes taken by the motor vehicle at the respective times and days.
- the driver of the motor vehicle may travel to his workplace at approximately the same time each morning from Monday to Friday.
- the area is predetermined in such a way that the area comprises at least part of this predetermined route.
- it can be determined particularly reliably, for a route most likely to be taken by the driver, which digital radio stations will be receivable along this route, so that only these digital radio stations are also displayed for selection.
- the size and the shape of the area depending on a straight from the car used road type is specified. If the car, for example, drive a highway, and in the straight section of the route also no motorway exits and exits should be present, it makes sense to restrict the area to a relatively narrow tube, which essentially corresponds to the highway currently being used.
- the area may be chosen somewhat more spaciously, in particular also transversely to the direction of travel that has just been taken, so that a possibly largest area is covered in order to anticipate possible turning operations can and thus be able to determine with particular reliability which digital radio stations can still be received in the future without interference, so that only these digital radio stations are displayed for selection.
- the size and shape of the area is predetermined as a function of a predetermined uninterrupted minimum reception duration of the digital radio stations.
- a selection menu can be provided by means of the radio system, by means of which the driver of the motor vehicle can select how long he wishes at least a trouble-free reproduction of the respective digital radio station. If he wants a particularly long trouble-free minimum reception time and playback duration, the area is chosen to be correspondingly larger than if the driver did not want a very long minimum reception time and trouble-free playback time. Preferably, only those digital radio stations are displayed that have the predetermined minimum reception duration.
- the driver of the motor vehicle can pretend via the corresponding selection menu that he does not wish to receive a particularly long minimum reception duration but rather a particularly high number of digital radio stations.
- the area is chosen smaller than if a particularly long minimum reception period should be desired.
- the respective minimum reception duration for the digital radio stations may be automatically reduced, so that a larger selection or number of digital radio stations is displayed.
- the radio system according to the invention for a motor vehicle comprises a control device which is designed to specify a region surrounding the motor vehicle and to determine which digital radio stations can be received without interference within this area by means of a receiving device of the radio system and to control a display device of the motor vehicle in such a way that only those digital radio stations are displayed, which are receivable without interference within this area.
- Advantageous embodiments of the method according to the invention are to be regarded as advantageous embodiments of the radio system according to the invention, wherein the radio system has in particular means for carrying out the method steps.
- the motor vehicle according to the invention comprises the radio system according to the invention or an advantageous embodiment of the radio system according to the invention.
- Fig. 1 is a schematic representation of a motor vehicle, which a
- Radio system for receiving digital radio stations
- FIG. 2 is a further schematic representation of the motor vehicle, wherein a region surrounding the motor vehicle is schematically drawn and a wireless connection between the force dare and a vehicle-external server device is shown schematically.
- a motor vehicle 10 with a radio system 12 is shown in a schematic representation in Fig. 1.
- the radio system 12 comprises a control device 14 and a receiving device 16, which is designed to receive digital radio stations.
- the control device 14 is also connected to a display device 18 of the motor vehicle 10 and designed to control the display device 18 to display different digital radio stations A, B, C.
- Fig. 2 the motor vehicle 10 is shown in a further schematic representation, wherein a motor vehicle 10 surrounding area 20 is shown.
- a method for operating the radio system 12 will be explained in more detail.
- the region 20 surrounding the motor vehicle 10 is initially specified.
- the extent or size of the area 20 is adjusted by the control device 14, the greater the faster the motor vehicle 10 drives.
- the area 20 is predefined such that the area 20 comprises at least part of the navigation route 22 or the entire navigation route 22. If no navigation route 22 of the motor vehicle 10 is known, then the control device 14 is designed to determine a probable route depending on the day of the week and in consideration of previously traveled with the motor vehicle 10 routes and specify the area 20 such that the area 20 comprises at least part of the prospective route. In other words, depending on an estimated direction of travel of the motor vehicle 10, the area 20 is determined accordingly.
- the size and shape of the area 20 may also be predetermined in response to a type of road currently being traveled by the motor vehicle 10. If, for example, the motor vehicle 10 is currently driving on a motorway, the area 20 in the direction of travel is rather elongated, since Licher way on highways relatively few driveway and departure options exist. If the motor vehicle 10 instead travels, for example, a country road from which particularly many roads lead away or lead into the highway, the area 20 is preferably relatively long and relatively wide, for example circular, so that any turning operations on roads branching off the highway are also taken into consideration can be.
- a file for example in the form of a digital reception card, stored in which is deposited, which digital radio stations are location-dependent interference-free receivable. Using these files, the controller 14 determines which digital radio stations in the predetermined area 20 are receivable trouble-free.
- the file is updated within predetermined time intervals, for example weekly, monthly or the like.
- the radio system 12 is thereby configured to establish a wireless connection 26 with an off-board server device 28 to update the said file.
- an off-vehicle server device 28 On the off-vehicle server device 28, a corresponding file, for example, also in the form of a digital reception card, are provided in which is deposited, which digital radio stations are location-dependent interference-free receivable. Due to the continuous vehicle-side update of the file in which is deposited, which digital radio stations are location-dependent interference-free receivable, for example, can be responded to weather-related Empfangsschwan- activities of the digital radio station in a simple manner.
- the car 10 either directly by means of a car-to-car communication the Updated vehicle-stored file or alternatively - as already mentioned - an update of the file by building the wireless connection 26 with the vehicle-external server device 28 makes.
- a selection menu can be provided, by means of which the driver of the motor vehicle 10 can determine which uninterrupted minimum reception duration or uninterrupted minimum reproduction duration of the digital radio station he wishes.
- control device 14 can on the one hand set the size of the area 20, which is monitored with regard to the reception quality of the digital radio stations, and filter those digital radio stations which are actually displayed for selection by means of the display device 18. Additionally or alternatively, it is also possible that the driver can select, for example via a corresponding selection menu, that he would prefer to have more digital radio stations displayed. If he selects the number of digital radio stations to be displayed particularly high, it can be provided that the trouble-free minimum playback time per digital radio station is automatically reduced.
- the driver can therefore choose for himself whether he wants a particularly long trouble-free playback of the respective digital radio stations, which should be displayed to him, or instead would like to get more digital radio stations displayed, but in this case there is a risk that the continuous trouble-free Playback of this digital radio station is relatively low.
