Definitions

  • the invention relates to a method for determining a transmitter order and a transmitter selector for a radio receiver in a vehicle.
  • TMC messages digital coded traffic announcements
  • the user request of the audio program initially determines the reception of traffic announcements. If the selected audio transmitter does not offer a TMC channel, no messages can be received. Even if the user selects a TMC-capable transmitter, there is no guarantee that this transmitter will be available throughout his journey. If necessary, the user must search for a TMC-capable transmitter again when leaving the transmitter area.
  • At least one tuner can be used to receive traffic announcements, regardless of the desired audio program.
  • the user can - regardless of the audio program - either manually select a suitable TMC station or automatically search for a suitable station.
  • TMC transmitters are suitable if TMC messages are transmitted in principle and their spatial assignment corresponds to the decoding tables of the terminal. Recognition takes place in TMC through a special identifier, which is transmitted together with the message and refers to a special decoding table. If several TMC transmitters are suitable, it must be decided on the basis of further criteria which transmitter is to be selected. In current systems, a suitable transmitter is selected either arbitrarily or according to local reception characteristics, such as the magnitude of the field strength. This means that the TMC transmitter can be changed unnecessarily often during a journey, because, for example, a transmitter temporarily becomes weaker and later becomes stronger again without the reception being interrupted.
  • a method is known in which a list of transmitters which emit digital coded traffic reports (TMC messages) is stored in a memory.
  • the list is organized according to PI codes and contains in each case a PI code a reception area, a message area, frequencies on which programs are transmitted with the respective PI code and the other message selections carried out by the transmitter.
  • a navigation device determines, based on its own position, in which PI area the vehicle is located and can then jump directly to the corresponding section of the PI code table where it then finds one or more PI codes for the area. If there are several PI codes, the route is first checked to determine which road classes are used. If the first route is initially not a motorway, then if, for example, a local and a supra-regional transmitter are available in the area, the local transmitter is preferred. If the motorway is reached later, the supraregional transmitter is chosen.
  • a corresponding regional transmitter is preferred, instead of a nationwide transmitter.
  • the method has the following steps: Provision of a memory device in which at least one transmitter or several transmitters and at least one or more areas are stored which are assigned to one or more of the transmitters. For example, the transmitters and their transmission areas can be stored. Furthermore, a route is provided. Between the route and the stored areas, which lie in the area of the route course, a correlation is created and the transmitters are selected on the basis of the areas, so that the number of transmitters for covering the route course is as small as possible.
  • Another advantage is that by storing transmitters and areas that are assigned to the respective transmitters, a targeted and thus fast station search can be achieved immediately after switching on the device, with no time-consuming Band Scan is required.
  • the route in order to carry out the correlation between the course of the route and the transmitters, the route is first broken down into individual segments, each segment corresponding either to no transmitter area, one transmitter area or multiple transmitter areas. Further, the transmitter area is selected, which has the largest contiguous portion of segments of the route. is For example, if the route has not yet been completely covered, this step is repeated for the next transmitter area, which has the next largest contiguous portion of segments of the route until the entire route through the selected transmitter areas is covered at least as far as possible or completely. Then the respective transmitter is determined based on the selected transmitter areas.
  • the boundaries of the transmitter regions form or determine the segments. In this way, the segments can be assigned to the transmitter areas very easily.
  • no transmitter is determined or searched for a segment section which can not be assigned to a transmitter.
  • an unnecessary search by means of a tape scan in this area can be avoided.
  • the transmitter areas are then selected so that first the transmitter area is selected, which has the largest contiguous portion of segments of the line. If the line in this case is not yet as far as possible or completely covered, then the transmitter area with the next largest part of segments of the line. This has the advantage that no complete route, for example, must be provided via a navigation system. Furthermore, the process can be carried out relatively quickly.
  • a corridor is placed between the starting point and the end point of the route.
  • a transmitter area is selected such that it has the largest contiguous portion of segments of the corridor. If a contiguous course of the corridor from the start point to the end point is not yet as far as possible or substantially completely covered, a next transmitter area is selected. In this case, the next transmitter area has the next largest part of contiguous segments of the corridor, etc.
  • the corridor also has the advantage that no detailed route is needed and therefore determining the transmitters can be carried out relatively quickly and easily.
  • no transmitter of a selected transmitter area is then determined if the route course, for example, leaves a transmitter area only briefly, for example for up to 1 km or 2 km, and thereby runs in another transmitter area.
  • no transmitter can be determined, because the route outside the first transmission area contains no intersections and / or departures. In this way, very short switching between stations can be avoided.
  • transmitter areas as areas.
  • other areas may be used instead of transmitter areas, for example, areas i.S.v. individual federal states or states or cantons or regions of a country, to name but one example of many.
  • a method and a transmitter selection device which, taking into account the current location or an assumed route of a vehicle, an optimized selection of TMC transmitters allow the transmitter areas or transmission ranges of the TMC transmitter are known.
  • An optimized selection means that TMC stations are quickly found and changed as rarely as possible while driving.
  • the destination is known, for example, by active route guidance by means of a navigation system, the corresponding station is determined when the station is selected taking into account the course of the route and its regional range, whereby a change of the station is kept as small as possible.
  • the respective transmitter is preferably selected such that the route of the vehicle in this case runs as close to the center as possible relative to the transmitter location. In this way, the best possible reception of the transmitter can be achieved.
  • the EP 1 118 068 B1 stored in a memory a list of transmitters which broadcast TMC messages.
  • the list is arranged according to PI codes and contains in each case a PI code, for example, a reception area and a message area, as well as frequencies on which programs are sent with the respective PI code.
  • the present invention presupposes the knowledge of transmitters and their geographic extent.
  • a transmitter selection device with a transmitter selection component and an integrated method for the optimized selection of transmitters, such as TMC transmitters.
  • the transmitter selection component can, for example, directly set a desired TMC transmitter at the request of the user.
  • the transmitter selection component first requires the current position, the destination and the course of the route. This receives it, for example, from the navigation system of the vehicle or a statistical component or a Historical memory of driving in the vehicle, the or the routes that the vehicle has covered, stores and estimates based on the stored routes a route.
  • the detection and storage of transmitter areas is in the above EP 1 118 068 B1 described.
  • the last selected TMC transmitter can be stored at power off and set again at power up. However, if the vehicle position has changed or this transmitter is not receivable, since e.g. If the journey begins in a garage, a so-called band scan must first be performed after switching on to find at least one suitable TMC transmitter. By contrast, by means of the stored extent of the transmitter regions, a suitable TMC transmitter can be set directly after the start, which means that the search time for the band scan is omitted here.
  • Fig. 1 an example of a station search is shown.
  • the starting point of the route of a vehicle in the transmitter area of the TMC transmitter A dashed line 22
  • the destination point of the route in the transmitter area of the transmitter B solid line 24.
  • part of the route lies in an area that is detected neither by the transmitter A nor by the transmitter B.
  • the stored extent of the transmitter regions A, B can be used to switch over to the transmitter B directly at point X 2. Traffic reports are not "lost".
  • Fig. 2 is another example of a station search shown.
  • the transmitter area A (dashed line 22) and the transmitter area B (solid line 24) together cover the entire route and partially overlap.
  • a tape scan For single-tuner systems, only one station can be tuned. If the transmitter area is left, a tape scan must be performed. During this time no traffic reports can be received. In Fig. 2 it is assumed that the tape scan corresponds to the travel time from X2 to X3.
  • the selection of the TMC transmitter is carried out in a known or estimated route history, the selection of the transmitter is such that as rare as possible transmitter must be changed.
  • Fig. 3 a first example is shown in which two TMC transmitters are received at the start position, the distance to the TMC transmitter A being shorter than that to the TMC transmitter B.
  • the automatic search first selects transmitter A. because its reception field strength is greater. In the further course of the route is switched to station B.
  • the transmitter selection component controls the tuner system so that transmitter A is not taken into account, but is used in the entire route transmitter B. The implementation of the correlation of the route with the transmitters will be explained later.
  • Fig. 4 the example is off Fig. 3 extended to three transmitter areas A, B and C.
  • the automatic search selects first station A, then station C, and in the further course of the route, station B due to the greater reception field strength.
  • Fig. 5 another example is shown.
  • the transmitter areas A and B are shown with an overlap.
  • the route of the vehicle runs hereby exclusively in the transmitter area A (dashed line 22).
  • the transmitter B is much closer and therefore more receivable than transmitter A.
  • the transmitter is switched over briefly.
  • the transmitter A is selected by a correlation of the route with the transmitter area A (dashed line 22) and the transmitter area B (solid line 24), as this covers the entire route, but not the transmitter B is switched in the meantime.
  • Fig. 6 another example is shown.
  • the transmitter area A dashed line 22
  • the transmitter area B solid line 24
  • the route of the vehicle runs almost exclusively in the transmitter area A.
  • the transmitter area A is left, while station B is receivable.
  • the given course of the route briefly switches to station B in the border area.
  • the length of route sections outside the transmitter area can be used.
  • the limit value it may be set not to switch to the transmitter B when the route outside the transmitter A is not longer than, for example, 1km or 2km, these values being purely exemplary and the invention is not limited thereto, the values may each be depending on the application, also larger or smaller than 1km or 2km are chosen.
  • route sections that are outside the first transmitter area A (dashed line 22) but do not contain intersections / departures can also be used as a criterion that no station change is performed in the present case.
  • these criteria are merely exemplary and the invention is not limited thereto. It is crucial that the criteria are chosen so that as little as possible has to be switched between stations and on the other hand no or hardly any traffic reports can be lost.
  • the entire travel route is broken down into segments, with each segment either not being able to be allocated to exactly one or more transmitter areas.
  • the boundaries of transmitter areas here the transmitter area A (dashed line 22) and the transmitter area B (solid line 24) determine segments.
  • Fig. 1 For example, there is in each case a segment a * for the transmitter area A, a segment b * for the transmitter area B and a segment z * which can not be assigned to a transmitter area or transmitter.
  • Fig. 2 For example, there is a segment a * associated with the transmitter area A, a segment a * b * associated with the transmitter areas A and B, and a segment b * associated with the transmitter area B.
  • Fig. 1 For example, there is a segment a * associated with the transmitter area A, a segment a * b * associated with the transmitter areas A and B, and a segment b * associated with the transmitter area B.
  • the segments a *, b *, a * b * may denote the areas formed by the transmitter areas A and B, or lines of line 28 connecting the start and end points of the route.
  • the provision of the line 28 will be described in more detail below. Basically, both possibilities for all embodiments of the invention are conceivable, as they are based on Fig. 1 to 6 to be discribed.
  • the transmitter area is selected, to which the longest piece of contiguous segments of the route can be assigned, here, for example, first transmitter area A (segment a *) in Fig. 1 and transmitter area B (segments b *, a * b *) in Fig. 2 , If the route can not be fully covered, the longest piece of contiguous segments of the rest of the route will be selected, and so on Fig. 1 this is the transmitter area B (segment b *) and in Fig. 2 the transmitter area A (segment a *). Therefore, in Fig. 1 starting with the start position of the route, first switched to the transmitter A and on reaching the transmitter area B to the transmitter B. In Fig. 2 For example, starting with the start position, it is first switched to the transmitter A (segment a *) and then, for example, to the transmitter region B at the time X1 (segments a * b *, b *).
  • Start and end points are connected to a virtual line, as exemplified in Fig. 2 through the dashed line 28 is shown.
  • This line 28 is subdivided into segments, so that each section can either be assigned to no, exactly one or more transmitter areas.
  • the segments can be formed by surfaces or by line segments of the line 28.

  • the longest piece of contiguous segments of the remaining line 28 is selected, and so on Fig. 2 corresponding to the transmitter area A (segment a *).
  • segment a * b * which is assigned to both the transmitter area A and the transmitter area B has been assigned to the transmitter area B in the present case
  • a switchover from the transmitter A takes place at the point X1 it is also conceivable to select the transmitter area A as the transmitter area (segments a *, a * b *) with the longest connected piece of segments of the virtual line 28. In this case, at the point X2, the transmitter A would switch from the transmitter A to the transmitter B.
  • This method is easier to implement than the method a), since not the entire route course has to be taken into account, but a virtual line 28 is used, which connects a start and a destination point. But it may u.U. not quite as accurate as the method a), since the virtual line 28 only approximates the route.
  • the method works in a similar way to method b) but places a virtual corridor 30, such as a rectangle or ellipse, around the start and finish so that both points are included.
  • a virtual corridor 30 such as a rectangle or ellipse
  • the virtual corridor 30 is selected, for example, such that, when the route is used by the navigation system or the statistical component, it preferably completely encloses the course of the route.
  • the areas of the transmitter areas ie the transmitter area A (dashed line 22), the transmitter area B (solid line 24) and the transmitter area C (dotted line 26) are compared with the corridor area.
  • the subareas b *, a *, b * c * and a * b * c * are selected, which are assigned to, among other things, the transmitter area B and the transmitter area A.

  • This method is easier to implement than the method a), since not the entire route has to be considered. But it is u.U. not as well as the method a) if the corridor 30 does not confuse the actual route course.
  • the aforementioned methods are merely examples of how the route course and the transmitter areas can be related to each other in order to select the stations so that an unnecessary station change can be avoided.
  • a simplified schematic system for an optimized selection of TMC transmitters is shown, wherein the system is the previously described method performs.
  • the system has a transmitter selection component 10 according to the invention, which is part of a transmitter selection device. This is connected via an interface "1)" to a tuner system 12 of a radio receiver of the vehicle to tune the tuner system 12 to the selected station.
  • the transmitter selection component 10 is further connected via an interface "2)" with a navigation system 14 of the vehicle and / or with a statistics component for estimating a route course (not shown), wherein the navigation system 14 or the statistical component of the transmitter selection component 10 provides data such as the current position of the vehicle and the planned route of the vehicle from a starting point to a destination point.
  • a first memory device 16 is provided, via which the navigation system 14 and the transmitter selection component 10 are supplied via the interfaces "3)" or "4)", for example navigation data, such as position data, etc. Furthermore, in the first memory device 16, for example, a TMC location table is stored.
  • a second memory device 18 is provided, which is connected to the transmitter selection component 10 via an interface "5)". The second memory device 18 is a geographic transmitter landscape memory device in which, for example, transmitter locations and transmitter ranges, as well as transmitter IDs and transmitter names are stored. Via a user 20, the transmitter selection component 10 is controlled, and accordingly the tuner system 12.
  • the number of tuners is known or communicated, for example, by the tuner system 12 suitable for receiving traffic announcements.

  • the tuner system 12 here consists, for example, of three tuners, the number of tuners being merely exemplary. Basically, any number of tuners can be provided, starting with a tuner.
  • the goal is to specify exactly one special transmitter for each of the tuners 1-3 of the tuner system 12 by means of the interface "1)". In the case of TMC transmitters, this can be done simply and quickly by a so-called "PI code".
  • the corresponding tuner must independently search for a suitable transmitter.
  • the transmitter selection component 10 calls the country, with TMC the so-called country code "CC”, and the table number to be used, with TMC the location table number "LTN,” for which traffic reports are to be received.
  • the tuner is now looking for a "suitable" transmitter that meets the requirements. Once a station has been tuned for all available tuners, the tuner system 12 informs the station selection component 10 of the settings.
  • the requirements for the second tuner P2 can not be implemented directly because, for example, the reception of the transmitter of the second tuner P2 is disturbed.

  • An advantage of the invention described above is that a targeted and thus fast station search can be achieved immediately after switching on the device, whereby no time-consuming tape scanning is required. Another advantage is that a targeted and thus fast station search is made possible when entering a new transmitter area, especially in single-tuner systems. Furthermore, a strategic selection of TMC stations is possible with a known or predicted route history. This can avoid station changes and reduce the risk of inconsistent messages from different sources.
  • the present invention has been described using the example of the selection of transmitters of traffic information services.
