Definitions
- the invention relates to a method and a device for reducing an Vehicles of a sample vehicle fleet to be transferred from Vehicle data, information about the operating status and / or about the Environment of the vehicles included, and location data, the information about the Position of the vehicles in a predetermined coordinate system specific point in time at which the vehicle and position data in certain intervals, which a predetermined period of time or a correspond to the specified route, recorded and sent to a traffic computer be transmitted.
- Traffic or road condition data to a sample vehicle fleet use individual sample vehicles referred to as "floating cars" for example, predetermined vehicle data and associated data via radio Transmit position data to a receiving point of a traffic computer.
- the traffic computer can then use this data using predetermined algorithms Determine traffic situation or, for example, draw conclusions about environmental conditions such as wetness or icing of the road, fog etc.
- predetermined algorithms Determine traffic situation or, for example, draw conclusions about environmental conditions such as wetness or icing of the road, fog etc.
- a radio network such as Example a GSM network does not have unlimited capacity, causing it to overload of the network can come.
- the traffic calculator must be based on the predetermined algorithms from the received data sets Calculate information or predictions.
- the computing load of the Traffic calculator the larger the amount of data to be processed.
- the transmitted from each "floating car" in the fleet according to a fixed scheme data records almost always contain a part that is currently superfluous, so-called redundant data that unnecessarily increase the computing load, which may a. especially then the case is when multiple vehicles in the sample vehicle fleet share the same road or drive on the same type of road.
- a device for performing the method is to be specified.
- the invention provides that the detected vehicle and position data already in Vehicle of at least one predetermined class of vehicle and position data, that correspond to a certain typical vehicle behavior. These classes are called vehicle behavior patterns.
- the assigned Vehicle behavior pattern is compared with the position data of the sample vehicle transmitted at least partially in coded form to the traffic computer.
- a particularly strong reduction in those to be transmitted to the traffic computer The amount of data is achieved in that only the identifier of the assigned predefined vehicle behavior pattern with the position data of the sample vehicle is transmitted to the traffic computer.
- Electronic data acquisition and processing continues to be simplified in that the assignment of the detected vehicle and position data to by at least one of the predefined vehicle behavior patterns existing on-board computer in the vehicle, so that the required Hardware expenditure remains low.
- a particularly low computing effort when assigning vehicle behavior patterns the detected vehicle and position data can be achieved in that the assignment to at least one of the predefined vehicle behavior patterns done by the on-board computer using fuzzy logic.
- the transmission of the data to the traffic computer can expediently further reduce that current vehicle and position data assigned predefined vehicle behavior patterns with the immediately preceding the predetermined vehicle behavior patterns assigned to the vehicle and position data is compared and only if the two do not match Vehicle behavior pattern data is transmitted to the traffic computer.
- the classified data will only be transferred if there is a change of the Vehicle behavior pattern, which e.g. usually the case is when the road type was changed by the sample vehicle or the Traffic situation (traffic density) has changed. It is under certain Under certain circumstances advantageous if the two vehicle behavior patterns match only the position data is transmitted to the traffic computer.
- the traffic computer knows the exact position data of the Sample vehicle and knows due to the non-transmitted vehicle behavior pattern, that the last transmitted vehicle behavior pattern continues is valid.
- the assigned to the detected vehicle and position data predefined vehicle behavior patterns with one specifically from the traffic computer predetermined vehicle behavior pattern is compared and only at Agreement of these two vehicle behavior patterns to a data transmission the traffic computer is done.
- the specification can e.g. by submitting the Identification of this vehicle behavior pattern to all sample vehicles.
- the vehicle behavior patterns from Traffic computers are specified, advantageously via an installed Cellular phone network or other wireless connection.
- the Vehicle behavior patterns by classifying those that are constantly occurring in the vehicle Vehicle data can be determined by the on-board computer itself.
- the on-board computer searches using the acquired vehicle data with the aid of predefined computing algorithms typical classifications (vehicle behavior patterns) for vehicle behavior the basis of the assignment, i.e. as a predetermined vehicle behavior pattern act.
- the vehicle behavior patterns determined in this way are automatically changed by the on-board computer when the conditions change customized.
- the specified calculation algorithms ensure that the Traffic computer only data that are used to record the Traffic situation needed.
- the (predefined) vehicle behavior patterns determined by the on-board computer are displayed together with the associated location coordinates the traffic computer transmitted.
- Another advantageous embodiment of the invention provides that the Traffic calculator predefined vehicle behavior pattern regardless of Driving behavior of the driver. That will e.g. reached when the given Vehicle behavior patterns were averaged across many drivers.
- the specification of such vehicle behavior patterns that are independent of the driver's driving behavior make it possible that from the constantly occurring vehicle and position data Comparison with the specified vehicle behavior patterns, driving behavior patterns, that correspond to the typical driving behavior of the driver are determined; and that the driver's driving behavior patterns with every vehicle or driver change Hand over the on-board computer of the new or old vehicle in anonymized form can be.
- the handover could be in the form of magnetic cards or the like take place in a corresponding reading and writing device in Vehicle are introduced and a concordance between the generally applicable ones predefined vehicle behavior patterns and the corresponding one create individual driving behavior.
- a vehicle in a sample fleet has sensors installed in the vehicle; the sensors record continuously changing state variables such as B. the Speed, the steering wheel angle, the engine speed, the outside temperature, the Humidity, etc.
- the vehicle also has sensors that are discrete State variables, such as B. the position of various switches (wipers, Light, fog light, rear window heating, hazard warning lights, etc.).
- the Vehicle is also equipped with devices that in the vehicle Show operation of active devices (actuators) such as of the anti-lock braking system (ABS), the traction control system (ASR), the airbag, the accident data recorder (UDS) etc.
- the vehicle also has a GPS receiver (GPS equals global Positioning System) as a positioning device.
- the GPS receiver continuously generates position data at predetermined time intervals that the current position (length, width, time) of the vehicle in a predetermined Coordinate system (longitude, latitude) included, and if necessary direction and / or Speed data about the current direction of movement of the Vehicle.
- the from the sensors, the GPS receiver (movement data) and the Devices for displaying the operation of the actuators generate the data Vehicle data in connection with the corresponding position data (including the associated time data) information about the traffic situation and contain the road condition.
- the vehicle data are collected at regular intervals by an on-board computer queried and for example in a ring buffer or in a ring buffer organized normal storage in the form of records, so that all over vehicle data accumulated during a certain previous period is available are.
- Each data record includes the in a precisely defined order corresponding vehicle data, the time data, the position data, the Speed, the direction of movement and so on.
- the ring buffer will for example, continuously with new data records by overwriting the oldest Data records filled, so that only the time history of the vehicle data on the immediately preceding period is available for evaluation.
- the on-board computer retrieves the content of the Ring memory in the working memory and assigns that class to the vehicle data to which the data belongs.
- the specified vehicle behavior patterns advantageously stored in corresponding tables, so that the assignment to at least one of the predefined behavior patterns by the on-board computer can be done quickly with the help of fuzzy logic.
- the classes are generated by the traffic computer predetermined and each include the entirety of vehicle data that one correspond to certain typical vehicle behavior. That means one A large number of combinations of vehicle data is assigned to a single class, all of the vehicle data belonging to a class typical of the same Behavior of a vehicle in traffic.
- the cover from Traffic calculator given classes all practically possible combinations of Vehicle data from; each vehicle data combination can have at least one assigned to a given class.
- Two classes can use the data For example, be assigned if there is only one in the recorded period Driving on the highway and then the vehicle on one Rest area was parked.
- the classes are called vehicle behavior patterns designated. The assignment of the data recorded in the vehicle is strong Reduction in the amount of data connected.
- the classification corresponds to Vehicle data of a higher data quality, i.e. the recorded data indicate their Preparation in the form of the class assignment only has the characteristics required for the Further processing by the traffic computer, for example to determine the Traffic conditions are essential.
- To carry out the classification of the vehicle data is stored in the sample vehicle by the on-board computer in the memory Computer program started, the data according to a predetermined algorithm classified. If an unambiguous assignment of the vehicle data fails, then either the vehicle data is transmitted unprocessed or it is in this If no data is transmitted to the traffic computer at all.
- the classes are specified, i.e. of the Vehicle behavior patterns not through the traffic computer, but the classes are determined by the on-board computer based on the vehicle data.
- the on-board computer evaluates the vehicle data so that it can be used with the help predefined calculation algorithms typical, i.e. recurring Data combinations determine and this a class, a vehicle behavior pattern assigns.
- the class assignment of the vehicle data can e.g. thereby supported be that the driver via the on-board computer in the class recognition phase Pressing a button tells which driving maneuver he is currently performing or which one Road type he is currently moving with the vehicle, so the behavior patterns of the To capture the sample vehicle faster and more precisely.
- the full records of the Transfer vehicle and position data to the traffic computer only that assigned vehicle behavior patterns in the form of an identifier together with the Position data of the sample vehicle.
- the data transfer takes place via Radiotelephone.
- the current vehicle behavior pattern cyclically or under special conditions compared to the vehicle behavior pattern that immediately before that as the penultimate has been determined from the vehicle data by the on-board computer.
- the two agree Pattern either no information is transmitted to the traffic computer, or the traffic computer only the position data of the sample vehicle communicated.
- the latter has the advantage that the traffic computer also has the current knows the geographical positions of the sample vehicles of the fleet.
- the Traffic calculator can also use one of the vehicle behavior patterns for the sample vehicles Specify specifically so that a message to the traffic computer with The current vehicle position is only specified if this is from the vehicle data determined current vehicle behavior patterns with the specially specified pattern matches. This is e.g. then useful if for the traffic computer Calculating the traffic situation is only of interest on which streets in which Areas congestion occur; in such a case, the sample vehicles only the vehicle behavior pattern "traffic jam" specified, so that when a Traffic jams from the sample vehicles located there transmit data to the Traffic calculator takes place, but otherwise no data is transmitted.
- the vehicle behavior patterns specified by the traffic computer can be independent of the driving behavior of the respective driver, especially if in determining the behavior patterns of the sample vehicles across many drivers was averaged.
- the sample vehicles are expediently driver-independent Vehicle behavior patterns specified.
- To the different driving behavior of the To be able to take individual drivers into account is initially based on the current Vehicle data on the basis of those specified by the traffic computer driver-independent pattern determines at least one driver behavior pattern; this are then taken into account when classifying the vehicle data. So corresponds, for example, to the medium-sized vehicle behavior pattern "Autobahn" Vehicle speed of 130 km / h.
- An older or particularly careful driver drives on the highway e.g.
- the driver behavior patterns of the new driver could change On-board computer of the vehicle are transmitted by the traffic computer, if one Corresponding data exchange with identifying data between vehicle and Traffic calculator done. However, this is generally not desirable.
- the driver behavior pattern is based on, for example stored on a magnetic card or other mobile storage medium and that the driver of this storage medium when changing the vehicle a corresponding device in the vehicle reads, so that the On-board computer in this way about the typical driving behavior of this driver is informed.
- the driver behavior patterns are thus transferred entirely anonymous.
- the figure shows an embodiment of a device for reducing an Vehicles of a sample vehicle fleet to be transferred from Vehicle and position data.
- the device has a transmission and Receiver unit 1 for data transmission.
- the Device a central processor unit (CPU) 2 with a data bus 3rd connected is.
