DE102007047423A1 - Traffic message e.g. traffic message channel message, evaluation method for terminal, involves receiving traffic message using receiving unit, and examining message to check whether message contains user-specific information - Google Patents

Abstract

The method involves receiving a traffic message (V) e.g. traffic message channel (TMC) message, using a receiving unit (12) of a terminal (10). The terminal is provided with a category module (14), in which the message is examined so as to check whether the message contains user-specific information. An allocation of the message to a message category takes place when the information is recognized in the message, where the category concerns about a specific vehicle type e.g. passenger car, and a vehicle of a specific pollutant category or with a specific environmental protection equipment. An independent claim is also included for a terminal comprising a category storage device.

Description

The The invention relates to a method for evaluating traffic news in a terminal according to the preamble of claim 1. Furthermore, the invention relates to a terminal for receiving of traffic news according to the preamble of claim 12.

to Information of road users about current traffic news has established the so-called Traffic Message Channel (TMC). This is used to transmit traffic information, such as traffic jams. These Traffic information is constantly called non-audio Additional information about the radio with the Radio Data System (RDS), which then with a suitable Terminal can be received. This has under Another advantage is that important current information immediately can be passed on and received. Especially advantageous can this system be used in modern navigation systems, who are able to evaluate the received TMC information, for example, to ensure dynamic route guidance. Depending on the particular device can this traffic news the user according to as Information in the form of text, language, and / or graphical display be made available, with an evaluation automatically or on request by the user.

Each of the traffic disruptions is sent as a separate TMC message and is in the so-called Alert C standard ISO 14819 which has a list of more than 1400 events. Each TMC message contains several codes with which the respective event, such as "traffic jam" or "construction site", may contain the local situation of the event, a time limit of the message or further supplementary information.

Terminals for detecting such TMC messages are for example from DE 196 21 609 A1 known. From this document, the basic structure and content of TMC data is known. The likewise transmitted radio data system (RDS) information and TMC information are evaluated by processing either exclusively RDS data or exclusively TMC data within a specific time window.

Out The structure and content of the TMC message immediately shows that besides the location information, the event, the extent, the direction and temporal duration also include user-specific information are so far not evaluated separately in the terminal and that according to the user selectively also not so to provide.

According to the invention a method for evaluating user-specific information of a Traffic message proposed in which the incoming message first tested for the presence of user-specific information becomes.

Farther becomes a terminal with a receiver for receiving user-specific coded information and an evaluation unit for evaluating this information, proposed, wherein the evaluation unit includes a module in which, the traffic report then examined whether it contains user-specific information. In this case, the user-specific information in particular a TMC information or TPEG information. For example, the TMC message may be the user-specific information "only for trucks" contain. This user-specific or restrictive Information can be about the coding of the event itself, such as "transit for trucks locked" or by means of additional information provided in the TMC message become.

The incoming traffic information can then be one or more message categories be assigned. The user-specific ones assigned to the message categories Information can then be provided by the user in the one he desires One by one for each message or for the whole Category treated. In particular, the user may have a single message or one or more message categories of the Further processing in the system (transmission to the user, Inclusion for route calculation) or exclude this to submit. For this purpose, for example the output of the message selected by the terminal or be suppressed. The user can alternatively also a single message or one or more message categories select for transmission and this for example indicated by the terminal.

Thus, related to the message categories filtering the traffic message in the terminal can be achieved, so that it is then possible, the messages targeted, depending on the type of application to output the specific information only if the message category is selected for that user-specific information.

there The method can be used for different protocols with which the traffic news will be transmitted. In particular, the already described TMC message can be evaluated become. The method can also be used in other protocols for example, the Transport Protocol Experts Group (TPEG), this open international standard for sending multimodal Traffic news is suitable.

The Evaluation of the traffic report is done by being checked whether the message contains user-specific information. This can be done in different ways. So, for example the event of the traffic message itself then checked whether it contains user-specific information. Furthermore, it is possible to check if the traffic announcement contains additional information, so that this checked for the presence of user-specific information can be.

The Terminal can be carried out so that the Art or category of user-specific information that is output should be made by both the user and the terminal manufacturer can be determined;

In In one embodiment, the category is already through the type of vehicle (eg truck or car) or specific vehicle characteristics such as diesel or gasoline engine or by technical equipment (eg. As soot particle filter or catalyst) or for example the pollutant class is determined. In modern vehicles could this via appropriate interfaces to the engine control unit be determined. Alternatively, these vehicle-specific relevant categories also already in the factory of the vehicle manufacturer be assigned by configuration (so-called "band end") Configuration).

Out The variety of possible message categories are suitable in particular, such message categories, the specific vehicle type information such as "just truck" or "just a car", environmental information For example, driving restrictions or restrictions on Vehicles that do not meet certain environmental criteria, or user-specific information that is a selected Dynamically influence the route. To the last mentioned user-specific Information includes, for example, accident reports or general disruptions of traffic flow, which then, for example assigned to a message category "dynamic route" can.

Farther can the decision of whether a traffic report a message category is to be issued by the user. It can in the terminal also be stored, whether or which message categories preferred by the user to be selected for output. This allows the individual wishes of the user be taken into account in a simple way.

Further Advantages and advantageous embodiments of the invention are the subject of the following figures and their parts description. They show in detail:

1 : schematically a terminal

2 : schematically the course of the method according to the invention

3 schematically an exemplary selection menu in the terminal

1 schematically shows a terminal 10 according to the present invention. The terminal has a receiving unit 12 on with the traffic messages V can be received. For example, these traffic messages V are received in coded form as TMC messages or TPEG messages. In addition to the location information specifying the local validity of the message, TMC messages include a so-called event and an event code, such as those shown in the following table: event event code Transit blocked for truck 403 Loss of time for trucks 1609 Passage blocked for heavy traffic 404 Time loss for heavy traffic 1642 locked for heavy traffic 494

In order to can already in the event or in the event code itself be contained information with which the message of a specific message category. For example, results directly, that the measure 403 concerns an event that only is relevant for trucks. Thus, this message can be a message category Trucks are assigned.

Furthermore, the TMC message as part of its protocol transmits so-called supplementary information together with a code. Examples for this are: additional information code Only for cars 71 For vehicles with catalytic converter 73 For vehicles without catalyst 74 Only for diesel vehicles 66 Only for vehicles with trailer 76

Also from the supplemental information can, as in the examples shown information about whether the Message is attributable to a specific message category.

To assign the messages to a specific message category, these categories must first be defined. This can be done, for example, by the user of the terminal himself, who then defines the message categories important to him. It is also possible, the message categories already factory by the manufacturer of the terminal in a category memory 18 store. In addition, the possibility may be provided of further message categories by the user in memory 18 add or modify existing message categories.

• – Dynamisierende Meldungen – Meldungen, welche eine gewählte Route verändern
• – Baustellenmeldungen
• – Unfallmeldungen
• – Allgemeine Störungen des Verkehrsflusses
• – Allgemeine Informationen, wie „Parkplätze voll"
• – spezielle Fahrzeugtypen wie „PKW", „LKW"
• – Umweltmeldungen wie „mit Katalysator" oder „für unterhalb Schadstoffklasse EURO 3 gesperrt"

Message categories can be defined as groups of messages that have common characteristics. For example, you can specify:

• - Dynamic messages - Messages that change a selected route
• - Construction site reports
• - accident reports
• - General disturbances of traffic flow
• - General information, such as "parking lots"
• - special vehicle types such as "car", "truck"
• - Environmental reports such as "with catalyst" or "for below pollutant class EURO 3 blocked"

In the terminal 10 is now a category module 14 provided in which it can be determined whether an incoming traffic message V should be assigned to one or more message categories. In this case, the event itself, its event code, the supplementary information or its code can be used for the analysis.

In an advantageous embodiment of the invention, the user can specify whether the messages of a message category are to be further processed in the system, that is, for example, on a display 16 of the terminal 10 should be displayed or included in the route calculation.

• a) Anzeige (als Symbol in der Karte oder als Text in einer Liste) und/oder
• b) Sprachausgabe und/oder
• c) Einbeziehung in die Routenwahl bzw. die Reisezeit erfolgen soll. Auch die Art der weiteren Verarbeitung der Meldung kann von einem Benutzer durch eine Eingabe festgelegt werden.

Basically, it can be distinguished first of all whether the user ignores the information (ie no further consideration in the system), would like to confirm it himself, in particular manually or acoustically, or wishes an automatic further processing by the system. Then, after the confirmation or in the case of automatic processing, it can be discriminated whether this is done by

• a) display (as a symbol in the map or as text in a list) and / or
• b) voice output and / or
• c) inclusion in the route choice or travel time should be made. The type of further processing of the message can also be determined by a user by an input.

2 shows schematically the flow of the method according to the invention for evaluating a traffic message. It is in the starting step 20 in the terminal 10 first a traffic message V recorded. Subsequently, in the category check step 22 This traffic message, which is present as a TMC message, for example, checks whether this traffic report can be assigned to one or more existing message categories. The category type of the traffic message V can be determined when a simple message from the event or the event code is present. Likewise, in the case of composite traffic reports, the message category can be determined from the events or event key figures. In addition, it is possible to determine the message category from the supplementary information or the associated code. If an associated message category is recognized for a traffic message, it is displayed in the assignment step 24 assigned to the message category. The user can then in the optional step 26 decide how to deal with this and possibly other messages of this message category.

• – Parkplätze für LKW belegt, oder
• – Tank- und Rastanlage ausgelastet für LKW, oder
• – Parkplatz belegt für LKW
• – Wartezeiten für LKW

Specifically, a traffic message having an event and supplementary information may be constructed, for example:

• - Parking occupied for trucks, or
• - Tank and resting system busy for trucks, or
• - Parking occupied for trucks
• - Waiting times for trucks

• – Meldung einmalig ignorieren
• – Meldung und alle ihre Aktualisierungen ignorieren
• – Alle Meldungen dieser Kategorie ignorieren
• – Meldung einmalig im Endgerät verarbeiten
• – Meldung und alle Aktualisierungen verarbeiten
• – Alle Meldungen dieser Kategorie im Endgerät verarbeiten.

These traffic reports can be assigned to the message category Truck. If such a message of this category to the user, for example by an indication on the display 16 of the terminal 10 output, the user can decide how to proceed with this message and the entire category. In particular, the following possibilities can be proposed:

• - Ignore message once
• - Ignore message and all its updates
• - Ignore all messages in this category
• - Process the message once in the terminal
• - Process message and all updates
• - Process all messages of this category in the terminal.

• – als Text und/oder
• – als graphisches Symbol und/oder
• – als eingefärbter Straßenzug und/oder
• – in der Sprachausgabe berücksichtigt
• – oder Kombinationen dieser Auswahlmöglichkeiten

werden soll. Entsprechend wird vom Endgerät dann weiter verfahren.If the user decides, for example, that all messages of this category are processed in the terminal, then another selection menu can be offered. In this menu, the user can decide if the traffic message

• - as text and / or
• - as a graphic symbol and / or
• - as dyed street and / or
• - included in the speech output
• - or combinations of these choices

shall be. Accordingly, the terminal then moves on.

According to the invention, it is also possible to automate both the decision process for the further procedure with the traffic message V and the categorization of the traffic message by a preselection, the so-called preset in the terminal. For this purpose, as in 3 illustrated by way of example, the feature categories K1, K2, K3 assigned procedures that in the example of the 3 "Display text", "Display graphic", "Display card", "Speech output". For each of the feature categories K1-K3, it is now possible to individually determine how traffic messages of a specific feature category are to be handled. With the selection shown, traffic messages of the reporting category K2 are only displayed graphically, for example in the form of an icon, while traffic reports of the reporting category K1 are displayed as text and graphics, displayed in the map and output by the system as a voice message. There is no issue for traffic reports of category K3.

With this preset, the user has the opportunity to prevent an output of uninteresting for him traffic reports a message category completely or partly without consultation. For example, the driver of a car can prevent all messages for trucks and at the same time the messages for Have a car delivered. Similarly, messages based on environmental or environmental aspects can be further processed or prevented in the system.

The Further processing can be an acoustic or graphic output, but also a consideration in the route calculation mean.

From The method is particularly advantageous if a message has several Categories is assigned. The message "blocked for Vehicles without catalyst ", for example, in the message categories Passenger cars, trucks and eco are grouped. Is by the user the category truck is suppressed when issuing, so gets the user about the assignment of the message to cars and eco nevertheless the important traffic message for him.

If the categories can also be specified by the user, a possibility has to be provided to assign the incoming traffic reports to a category. For this purpose, the user can be offered on the arrival of a previously un-categorized message, a selection menu, with which he can assign this message one or more categories. This selection can then be made in the terminal 10 get saved.
