Definitions
- the invention relates to a method and to a device for the selection of traffic information for a motor vehicle.
- a thing Method and such a device are already well known.
- the driver of a Motor vehicle before the start of a ride one installed in the vehicle Telematics terminal tell, for which geographical area he Traffic information wishes.
- appropriate information in the telematics terminal are entered manually, such as that the driver in the future only within a city to move wishes or intends, for example, on an overland route or Highway to a distant destination.
- traffic information is displayed or communicated to him for a circular area with a predetermined radius around the Motor vehicle is relevant around.
- the driver can also change the size of the radius itself.
- the driver only transmitted traffic information for a predetermined Area around the motor vehicle and for that area applies in which the motor vehicle is moving in the direction of the destination.
- the area for which relevant traffic information is obtained quasi keyhole-shaped. Again, you can Radius and distances selected by the driver before starting the journey or specified by the system.
- a disadvantage of the known method is that the driver before driving the respective areas for which he wishes traffic information, must select yourself.
- suitable filter parameters in the Telematics terminal can be entered by the out of a large amount traffic information only filters out those who are on refers to the area selected by the driver.
- filter parameters for the selection of traffic information not desirable, however, as it adds an extra burden representing the driver and possibly distracting him if he makes a setting while driving.
- the invention is based on the object, a method and an apparatus of the aforementioned type so that a simpler and less time-consuming yet highly accurate selection of areas, is desired for the traffic information is possible.
- the movement profile of the motor vehicle can to different Be determined manner, for example, by on-vehicle Accelerometers and direction sensors on the one hand or on the other hand by radio position sensors operating in conjunction with timepieces, about GPS receiver, and the like. Along with the movement profile of the motor vehicle then serves its current position to select the relevant traffic information, so to choose of that area, for the traffic information on the part of the driver it is asked for.
- the selection of the traffic information for example, directly take place in the telematics terminal of the motor vehicle, for example, then if traffic information for very large geographical areas of public Emitters emitted by the mass of road users Will be received.
- the one for the very large geographical Territories applicable traffic information in a telematics terminal the motor vehicle belonging traffic information memory cached and with each broadcasting cycle of public broadcasters updated or brought up to date. From this cached so Traffic information then becomes relevant to the driver Traffic information depending on the movement profile of the Motor vehicle filtered out or selected, depending on of filter parameters due to the motion profile of the motor vehicle to be generated.
- the selection can additionally in Dependent on changes in the direction of travel of the motor vehicle. Travels the motor vehicle at a relatively low average speed and occur at the same time relatively high mean changes in direction of the Direction, it is assumed that the motor vehicle within of a city area. In this case, the area for the traffic information is to be transmitted to the driver, circular wrapped around the motor vehicle, and with a relatively narrow radius. In contrast, the motor vehicle moves at a relatively high average speed (above the given speed value) and occur at the same time relatively small mean changes in direction of the direction of travel of the motor vehicle, it is assumed that the Motor vehicle on a freeway or freeway towards a moved to a distant destination. In this case, the filter parameters become selected or generated so that the traffic information relevant Area extends in the direction of the route to the destination, as already mentioned above.
- the motor vehicle When starting the motor vehicle is generally still no movement profile of the motor vehicle, so that then traffic information automatically from a circular area of predetermined radius the motor vehicle is selected around, in which case the radius is relatively large. After recording the movement profile of the motor vehicle then the radius can be reduced accordingly when the motor vehicle remains in the city area, or it becomes the relevant area for Traffic information hose towards a more distant destination extended, if the movement profile of the motor vehicle accordingly changes.
- speeds and direction changes of the motor vehicle is determined in each case at predetermined time intervals, to keep the traffic information selection as up to date as possible.
- new filter parameters are thus each time due to the respectively obtained during said periods of time mean speed and directional values generated, what a ensures some momentum of the selection process.
- the filter parameters valid for the respective periods constantly updated and related to the location of the motor vehicle traffic information 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 geographic area lets through; a filter parameter generator for automatic Generation of the filter parameters only as a function of a time-dependent Motion profile of the motor vehicle and its current position; and an output device to output the transmitted traffic information.
- the filter parameter generator is doing with a device for speed and delivery Direction of the vehicle and a device for detecting the current vehicle position connected.
- Such a device may be, for example, in a telematics terminal located in a motor vehicle.
- Telematics terminal would then be the filter parameter generator on the input side with a device for the delivery of the movement profile connect the motor vehicle, this device for Example speed and direction of travel, possibly derived therefrom Average values, transmits to the filter parameter generating device.
- the Output device would then be an optical or acoustic display device for transmitting the selected traffic information to the Driver of the motor vehicle.
- the filter device with an input-side storage device for storing received Traffic information to be connected.
- the filter parameter generating means a receiver connected, which receives the motion profile from the motor vehicle and its position and to the filter parameter generator transfers.
- the output device would be then a transmitter means for selecting the selected traffic information to transfer to the requesting motor vehicle.
- the filter parameter generator could in this case but also in the motor vehicle be accommodated, so that only the Filterparamater to the transmitting end would be available to transmit existing filter device.
- a telematics terminal 2 inside a motor vehicle 1 a telematics terminal 2, of which only those relevant to the invention Blocks are shown.
- the telematics terminal 2 includes a filter device 3, the traffic information supplied to it depending on filter parameters 4 filters. Filtered traffic information 5 then passes to an output device 6, the output side with the filter device 3 is connected and to output the filtered traffic information 5 serves, for example, optically or acoustically.
- the traffic information supplied to the filter device 3 4 is dependent on filter parameters 7 derived from a filter parameter generator 8 output and the filter device 3 are transmitted. These filter parameters 7 are input to one Filter algorithm used by the filter device 3 for filtering the Traffic information 4 is executed.
- At the traffic information 4 is coded information in that it is an indication contains about the place to which it applies.
- the traffic information 4 is in one Traffic information memory 10 cached in the constantly updated traffic information 4 of for example public Stations will be re-saved, with no longer valid traffic information is deleted or overwritten.
- This device 9 may be, for example, a those acting directly on the movement profile of the motor vehicle 1 detected, that is local. It does not have to detect the absolute position of the vehicle. For this purpose, other facilities are available, for example a GPS receiver, or the like. Rather, it is sufficient if the Setup 9 only the current direction and speed values of the motor vehicle detected. From these directional and speed values, from which also mean directions and speed values can be determined are then by the filter parameter generating device 8 shows the associated filter parameters 7, for example based on a suitable table.
- the device according to the invention initialized 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 around and has a predetermined radius R as shown in FIG.
- the whole received traffic information 4 is thereby using the filter device 3 filtered.
- the predetermined radius R has a mean Size of for example 50 km up, since at that time still not exactly It is known whether the motor vehicle will only move locally or one Long distance travel is intended.
- the facility After the vehicle has been driving for a short time, the facility will 9 shows the first movement data to the filter parameter generation device 8 delivered.
- the filter parameters For example, drives the vehicle with relative low average speed and relatively high mean directional changes on, it is based on these measures in the filter parameter generating device 8 found that the vehicle is within located in a city area.
- the filter parameters become 7 set accordingly, on a circle 12 around the motor vehicle around with a radius R1, for example, at about 25 km is, as can be seen in Figure 3. This may be the minimum Radius act.
- the middle speed and the mean directional deviation does not change, so the driver of the Motor vehicle only transmitted traffic information, which is exclusive refers 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 filter parameter generator 8 determines suitable other filter parameters 7 selected to receive traffic information for only one area, which is essentially in the now valid middle direction of the vehicle. This is the area 13 in FIG 3.
- information for the area 12 becomes the driver transmitted.
- the filter parameters 7 are thus set, that information is obtained for the areas 12 and 13 shown in FIG is, so for a substantially keyhole-shaped area.
- 13 is essentially characterized by the radius R1, the middle or estimated direction of travel and one on this middle Direction of travel estimated estimated or predetermined opening angle W.
- the selection of the traffic information is repeated performed, with the appropriate data in terms of speed and the directional deviation over a period of time of about 10 minutes can be collected to make it the middle one To obtain values.
- the minimum time interval of the selection can therefore also be 10 minutes or more, so when driving for example on a Highway the keyhole-shaped area structure 12, 13 repeated is generated.
- the filter parameters are generated repeatedly, to constantly have the opportunity to be at the place of the Motor vehicle related traffic information to the driver can.
