Definitions
- the invention relates to a method for creating and sending of traffic-related data with sensors on board of a motor vehicle have been created, together with a Position information to a control center in which the data is evaluated and used to create traffic reports.
- the invention further relates to a telematics device for a Motor vehicle with inputs for connecting sensors, one Input for received coded traffic reports, one input for signals from a navigation device and a transmitting device for emitting formed from the sensor signals Data to a central office.
- Today's traffic announcement system is not satisfactory because it takes a significant amount of time until relevant traffic events are reported and then be broadcast via radio, with many road users miss the announcement of the traffic announcement because they just turned off the car radio at this time or have tuned into a station that does not have traffic information radiates.
- the latter problem can be solved by setting up a Traffic radio channel are fixed, the last traffic reports be stored in a memory and therefore can be listened to at any time.
- the memory is there organized in such a way that newly arriving messages are saved to the oldest Eliminate messages from memory (first-in-first-out).
- the idea has become known through traffic telematics terminals installed in the vehicle Position, driving speed and direction immediately to report from the traffic situation.
- For position determination becomes satellite-based global positioning System GPS and for the transmission of information to the Central uses the extensive GSM mobile network.
- the data "Driving speed and direction" can also be obtained from GPS data, but preferably from sensing the steering movement and from the sensor for the speedometer or the wheel sensors for a automatic braking system (ABS) can be removed.
- ABS automatic braking system
- To this Ways can get traffic data from the road users themselves are currently being transmitted to the head office. But it will be required to transmit the data either in a fixed time grid or due to certain events (Falling below a minimum vehicle speed for a minimum duration or similar). This is e.g.
- the present invention is therefore based on the problem an excessive load on a communication network to avoid telematics devices installed in motor vehicles.
- the method according to the invention thus provides that the through the data contained in the sensors is not immediately sent to the control center be forwarded if this data is relevant for a Traffic situation, but first in the Central existing and already in the form of traffic reports communicated knowledge is checked. Only if the Vehicle internally formed data compared to the stored Traffic reports contain new information, that will Send out to the control center with the telematics device. It is naturally appropriate that the traffic reports be transmitted on a separate channel and therefore immediately and automatically received by the receiver in the motor vehicle and can be saved. The often redundant transmission of data to the headquarters by the numerous road users can therefore be avoided according to the invention, so that a minimal burden on the communication network by the Transmission of traffic data is achieved.
- the information about the location of the reported traffic situation can therefore not only a specific location, but also dimensions in the form of areas or sections.
- the comparison of the current position with a localization code can be made possible by a conversion algorithm.
- a memory with a localization table is preferred for the assignment of the navigation device determined position to a localization code provided.
- the device shown receives via an antenna 1 and Traffic radio receiver 2 traffic news, preferably via a traffic radio channel of the broadcasting companies or one Mobile radio channel of a mobile radio service provider available for this be broadcast.
- the traffic announcement preferably contains one, for example according to the ALERT C protocol Coded information about the type of message and a Lokalisationskode.
- a central processing unit 3 of the Device ensures that the traffic announcement is stored in a memory 4, thus all current traffic reports, at least insofar as they are relevant to the current position of the motor vehicle can be contains.
- a GPS receiver 5 Used to determine the current position of the motor vehicle a GPS receiver 5 with which a position determination from satellite signals is possible. If necessary, the position determination with the help of signals from certain sensors of the Motor vehicle, such as ABS sensors or steering motion sensors, be refined.
- a connection module is also connected to the central processing unit 3 6 connected, the output signals of a series of sensors 7 and signals from a motor vehicle bus 7 '.
- the central processing unit 3 processes the data from the connection module 6 delivered signals to traffic-relevant Data and assigns them to the associated parts of the encoded Traffic announcement too.
- an assignment of the position generated by the GPS receiver 5 to the recorded Data instead, the geographic data being a location code assigned, which is derived from a location table 8 results.
- a correlation is then established in the central processing unit the generated and with the localization code Data on saved under the same localization code current traffic reports.
- Correspond to the data an existing traffic announcement, nothing further is caused.
- the data generated via the sensors 7 belongs to a not yet reported traffic event or change a saved traffic report, for example by determining the resolution of a reported traffic jam a corresponding message is generated and via a GSM transmitter 9 and a GSM antenna 10 to a central office broadcasting service provider.
- traffic reports stored in the memory can understood in the broadest sense within the scope of the present invention are, in particular traffic-relevant environmental data include, e.g. Fog, precipitation, temperature warning messages or the like. Accordingly, sensors 7 are created of traffic-relevant data has so far not been considered drawn information providers into question, e.g. the actuation a light switch during the day as an indicator of Fog or precipitation, a slip sensor of an ABS control as an indicator of slippery roads due to ice, snow or Wetness etc.
- traffic-relevant environmental data include, e.g. Fog. Fog, precipitation, temperature warning messages or the like.
- sensors 7 are created of traffic-relevant data has so far not been considered drawn information providers into question, e.g. the actuation a light switch during the day as an indicator of Fog or precipitation, a slip sensor of an ABS control as an indicator of slippery roads due to ice, snow or Wetness etc.
- the invention also makes it possible process traffic reports from other sources, for example the data from the motor vehicle sensors to interpret.
