Definitions
- the invention relates to a method for informing motorists, wherein digitally coded traffic reports are received and buffered.
- the Radio Data System enables additional and inaudible transmission of digital data in parallel to broadcast programs in one data channel.
- Specifications of the radio data system for VHF radio are inter alia in the publication Tech. 3244 - E, March 1984 of the European Union of Run-Down Radio Union (EBU).
- Radio receivers with suitable RDS decoders can record and decode transmitted data in addition to audio reception with the same receiver.
- For data transmission 32 groups of 104 bits each are provided, with each of the transmitted groups being assigned a specific service.
- the group 8a is currently provided for the transmission of digitally coded messages, in particular traffic reports.
- Digitally coded traffic reports - also referred to below as TMC messages for the sake of simplicity - can not only be transmitted with the aid of the radio data system, but also, for example, within the digital audio broadcasting (DAB), in particular in the FI channel (fast-forwarding). information channel).
- DAB digital audio broadcasting
- SMS Short Message Service
- GATS Global Automotive Telematic Standard
- Each TMC message is stored in a memory in the respective receiver and remains there until it loses its validity. This is implicit after a quarter of an hour (when transmitted via GSM after half a Hour) the case. For longer periods, the period of validity is explicitly transferred, for example, "another two hours”. If an obstacle lasts longer than initially assumed, the same message is sent repeatedly before it expires (update message). Traffic jams are usually reported in terms of kilometers. Frequently, however, it is much more interesting for the driver to know how long the traffic jam or other traffic obstruction still exists. When considering the use of a redirection, which is usually more complicated than the direct route, the timing of a traffic jam also plays a role.
- the EP-A-0 725 500 discloses a device for managing digitally encoded traffic reports, in particular TMC traffic jam messages, in which received and valid traffic messages are stored in a memory and for each traffic message a management record is stored, the time of first receiving the traffic message and the serial number of Traffic message according to the order of first reception.
- the DE-A-197 08 106 discloses a method for informing motorists of traffic disruptions, wherein traffic disturbance messages are received, for example as TMC traffic announcements via RDS broadcasting. Not only static information should be made available to the driver, but also information that allows conclusions to be drawn about the development of traffic disruptions over time.
- the traffic disturbances that are received are evaluated by means of a traffic flow-density diagram valid for this route section, which represents the connection between traffic flow and traffic density.
- the object of the present invention is to provide the motorist with information on the development of a traffic jam or another obstacle on the basis of the received TMC messages.
- This object is achieved with the method for providing a message in a vehicle to inform a driver about traffic related events according to claim 1, with the method for assigning a resistance value to a road for performing a route search on a navigation device for use in a vehicle according to Claim 2 and with the car radio according to claim 3 solved.
- the output can be visual or audible, with both a general tendency display and a more accurate display, for example in kilometers per unit time, is possible.
- the individual streets are assigned a resistance value.
- the duration and tendency are suitable to be used as a resistance value for a route search.
- Example shown arrives at 15:00 clock a new message and receives this time as a time stamp TST.
- Update messages arrive at 3:25 pm and 3:50 pm, but include increasing information about the traffic jam length. Therefore, the trend "rising" is derived when the update messages arrive.
- the issue at 15:55 then includes that the message is already 55 minutes and the congestion is also longer. Here it makes sense to follow a diversion recommendation.
- Fig. 3 represents a suitable for the inventive method receiver - preferably a car radio.
- An antenna 1 is connected in a conventional manner with a receiving part 2, at whose output a stereo multiplex signal MPX is present, which is a stereo decoder 4 and an RDS decoder 3 is supplied.
- Outputs of the stereo decoder 4 are connected to a low-frequency amplifier 5, to each of which an amplifier 6, 7 speakers 8, 9 are connected.
- the RDS decoder selects RDS signals from the multiplex signal and decodes them.
- a microprocessor 13 performs a number of functions, including the control of the entire receiver, with only those functions which are essential to the method according to the invention being mentioned below.
- the microprocessor 13 receives RDS signals from the RDS decoder and is connected to a control unit 14, a display 15, a memory 16 and a clock 17.
- the received TMC messages are as in the Figures 1 and 2 shown stored in memory 16.
- the display 15 can be controlled by the microprocessor 13. However, it is also a voice output, for example in the form of a speech synthesis, possible, for which the synthesized audio signals can be supplied via an input 10 to the low-frequency amplifier 5.
- various programs are executed, which perform the individual process steps.
- a new TMC message arrives from the clock 17, the time is read out and stored in the memory 16 together with the received TMC message.
- the time stamp TST stored in connection with the new message is read out of the memory 16 and stored together with the new message in the memory.
- This stored update message this is from the memory 16 read and displayed on the display 15 and the speaker 8, 9.
- the events (contents) of the update message and the previously received update message or new message are compared with each other and the tendency is determined and also reproduced.
