Definitions

  • the invention relates to a method and an apparatus for the selection of traffic information for a motor vehicle.
  • a thing Methods and such a device are already generally known.
  • the driver can Motor vehicle before the start of a trip installed in a motor vehicle Telematics terminal announce for which geographic area it Traffic information wishes.
  • appropriate information in the telematics terminal can be entered manually, for example in that that the driver will only move within one city in the future wishes or intends, for example on an overland route or Highway to a more distant destination.
  • he will then only be shown or informed of traffic information for a circular area with a predetermined radius around it Motor vehicle around is relevant.
  • the driver can also change the size of the radius itself.
  • a disadvantage of the known method is that the driver starts driving the respective areas for which he wants traffic information, must choose itself.
  • suitable filter parameters must be entered in the Telematics terminal can be entered from a large amount of traffic information is only filtered out to those who are on relates to the area selected by the driver.
  • filter parameters With ever increasing Number of electronic devices in a motor vehicle is the additional manual input of filter parameters to select traffic information however not desirable as it is an additional burden represents the driver and could possibly distract him, if he makes a setting while driving.
  • EP 0 789 343 A1 already describes a method for selecting received ones or traffic information to be transmitted is known in a vehicle, the selection depending on the type of street that the Vehicle is currently being driven.
  • a section Determination of the geometric course of the journey carried out the details of the respective section of the geometric At least the relative position of the start and end point this section to each other, and this section of the journey with characteristic geometric parameters of road types is compared, from which the currently used road type determines and is used as a selection criterion. It is characteristic, however, that no time considerations are required, but that one get by with geometric information about the course of the journey alone.
  • the invention has for its object a method and an apparatus of the type mentioned in such a way that a simpler and less time-consuming, yet highly accurate selection of areas, for which traffic information is desired is possible.
  • a method for selection selection of traffic information for a motor vehicle automatically and depending on a time-dependent movement profile of the Motor vehicle performed.
  • the driver therefore needs himself after the start his motor vehicle or switching on his telematics terminal at all no longer about the selection of the respective areas for which he traffic information desires to take care of but can care fully focus on the road, what driving in the car significantly simplified and more secure.
  • the movement profile of the motor vehicle can be different Be determined, for example by existing on the motor vehicle Accelerometers and direction sensors on the one hand or on the other hand by radio position transmitters working in conjunction with timing devices, such as GPS receivers, and the like. Along with the current position then serves the movement profile of the motor vehicle for the selection of the relevant traffic information, i.e. for selection of the area for which the driver receives traffic information it is asked for.
  • the selection of the traffic information can be immediate, for example in the telematics terminal of the motor vehicle, for example then when traffic information for very large geographic areas from public Broadcasters emitted and by the mass of road users Will be received.
  • the very large geographical Areas relevant traffic information in a to the telematics terminal traffic information memory belonging to the motor vehicle cached and with each broadcast cycle of the public broadcaster updated or brought up to date. From this so cached Traffic information is then relevant for the driver Traffic information depending on the movement profile of the Motor vehicle filtered out or selected, depending on of filter parameters based on the motion profile of the motor vehicle to be generated.
  • traffic information becomes available at the request of an individual road user for a desired area from a service provider transmitted, so could the selection of traffic information be carried out at the service provider, so that to the requesting road user only less information to be transmitted needs what lowers its user costs and that in the telematics terminal required space requirements reduced. To do this, however before the requesting road user his current position and the filter parameters derived from the movement profile of his motor vehicle transferred to the service provider.
  • the selection of the traffic information for example depending on the speed of the motor vehicle be performed.
  • the motor vehicle is moving at relative low speed and below a predetermined speed value
  • the filter parameters are automatically selected so that the traffic information only for a circular area around the Motor vehicle is transmitted around to the driver.
  • the Speed of the motor vehicle above the predetermined speed value, so the selection is made so that the driver only Traffic information for a relatively narrow and moving in the direction of travel range of the vehicle is reached.
  • the selection can also be carried out in Depending on changes in the direction of travel of the motor vehicle.
  • the motor vehicle drives at a relatively low average speed and occur at the same time relatively high mean changes in direction Direction of travel on, it is assumed that the motor vehicle is within of an urban area. In this case, the area for the traffic information is to be transmitted to the driver, circular placed around the motor vehicle, with a relatively narrow radius.
  • the motor vehicle is moving at a relatively high average speed (above the specified speed value) and At the same time there are relatively small changes in the direction of travel of the motor vehicle, it is assumed that the Motor vehicle on an expressway or freeway towards one distant target moves.
  • the filter parameters selected or generated so that the relevant for traffic information Area extends in the direction of the route to the destination, as already mentioned above.
  • Speeds and changes in the direction of travel are preferred of the motor vehicle in each case determined in predetermined time segments, to keep the traffic information selection as up to date as possible.
  • new filter parameters are thus created based on the respectively received in the periods mentioned generated average speed and direction values, what a certain dynamics of the selection process.
  • the filter parameters applicable for the respective time periods constantly updated traffic information related to the location of the motor vehicle filtered out or selected while on the other hand the traffic information stored in the traffic information memory always updated and overwritten accordingly can be.
  • a device for the selection of traffic information for a motor vehicle contains a filter device that depends on filter parameters Traffic information only for a given geographical area lets through; a filter parameter generating device for automatic Generation of the filter parameters depending on a time-dependent Motion profile of the motor vehicle; and an output device for output of the traffic information passed through.
  • Such a device can be found, for example, in a telematics terminal are located, which is installed in a motor vehicle.
  • Telematics terminal would then be the filter parameter generator on the input side with a device for supplying the movement profile connect the motor vehicle, this device for Example speed and direction of travel, if necessary also derived from it Average values, transmitted to the filter parameter generating device.
  • the output device would then be an optical or acoustic display device to transmit the selected traffic information to the Driver of the motor vehicle.
  • the filter device could an input-side storage device for storing received Traffic information.
  • the device were to be arranged on the transmitter side, then would be with the filter parameter generating device is connected to a receiver, which receives the motion profile from the motor vehicle and to the filter parameter generating device transmits.
  • the output device would be then a transmitter device to the selected traffic information to transmit to the requesting motor vehicle.
  • the filter parameter generator could in this case also in the motor vehicle be housed so that then only the filter parameters to the transmission side existing filter device would be transferred.
  • FIG. 1 there is a motor vehicle 1 a telematics terminal 2, of which only those relevant to the invention Blocks are shown.
  • a filter device belongs to the telematics terminal 2 3, the traffic information supplied to it as a function of filter parameters 4 filters. Filtered traffic information 5 then arrives to an output device 6, the output side with the filter device 3 is connected and for outputting the filtered traffic information 5 serves, for example optically or acoustically.
  • How the traffic information supplied to the filter device 3 4 is filtered depends on filter parameters 7, which are generated by a filter parameter generating device 8 output and to the filter device 3 are transmitted. These filter parameters 7 find their way into one Filter algorithm by the filter device 3 for filtering the Traffic information 4 is executed.
  • traffic information 4 it is encoded information in that it is an indication about the place to which it applies.
  • the traffic information 4 is in one Traffic information memory 10 buffered. in the constantly updated traffic information 4 from, for example, public Transmitters is saved again, traffic information no longer valid is deleted or overwritten.
  • a filter parameter generating device 8 Device 9 for delivering a movement profile of the motor vehicle 1 connected.
  • This device 9 can, for example, be a act such that the movement profile of the motor vehicle 1 directly recorded, that is local. It does not have to detect the absolute position of the vehicle. Other facilities are available for this, for example a GPS receiver, or the like. Rather, it is sufficient if the Device 9 only the current direction and speed values of the motor vehicle is detected. From these directional and speed values, from which also mean directions and speed values can then be determined by the filter parameter generating device 8 the associated filter parameters 7, for example an appropriate table.
  • the driver gets into his motor vehicle 1 and wants to change his individual Get route-related traffic information, such as from a Transmitting station that is sent to the mass of road users regularly for one very large geographical area valid traffic information he only needs to start his vehicle and start the journey to begin, whereby the device according to the invention initializes becomes. After a short time, the first filtered traffic information reaches him, which is displayed on the output device 6, for example.
  • This initial value characterizes a circular area 11 around the motor vehicle 1 and has a predetermined radius R, as shown in Figure 2.
  • the whole received traffic information 4 is thereby using the filter device 3 filtered.
  • the predetermined radius R has an average one Size of 50 km, for example, because at this point it is not yet precise it is known whether the motor vehicle will only move locally or one Long-distance travel is intended.
  • the device After the vehicle has been driven for a short time, the device will start 9 the first movement data to the filter parameter generation device 8 delivered. For example, drives the vehicle with relative low average speed and occur relatively high average changes in direction on, is based on these measured variables in the filter parameter generating device 8 found that the vehicle is inside a city area.
  • the filter parameters 7 set accordingly, namely on a circle 12 around the motor vehicle around with a radius R1, for example at about 25 km lies, as can be seen in Figure 3. This can be the minimum Act radius.
  • the driver of the Motor vehicle only transmits traffic information that is exclusive relates to this small area 12. Traffic information 4 for areas outside of this circular area is suppressed; she but remains stored in the traffic information memory 10 until it is overwritten.
  • the average vehicle speed is a relatively high one Value (above a predetermined average speed value) and the mean directional deviation is relatively small or smaller than a predetermined mean directional deviation, so by the filter parameter generating device 8 other suitable filter parameters 7 selected to receive traffic information for only one area, which is essentially in the mean direction of travel now valid of the vehicle. This is area 13 in FIG 3.
  • information for area 12 becomes the driver transmitted.
  • the filter parameters 7 are thus set so that information is obtained for the areas 12 and 13 shown in FIG for a substantially keyhole-shaped area.
  • the Overall area 12, 13 is essentially characterized by the radius R1, the average or estimated direction of travel and one based on this average Estimated or specified opening angle related to the direction of travel W.
  • the selection of the traffic information is repeated performed, the corresponding data regarding speed and the directional deviation over a period of time of about 10 minutes can be collected to get the mean To get values.
  • the minimum time interval for the selection can therefore also be 10 minutes or more, so that when driving for example on a Autobahn repeated the keyhole-shaped area structure 11, 12 is generated.
  • the filter parameters are generated repeatedly, to always have the opportunity to go to the respective location of the Transport-related traffic information to the driver can.
