Definitions

  • the invention relates to a method for determining traffic information using in a motor vehicle data recorded by sensors from the motor vehicle with a Transmitting device to be communicated.
  • the invention relates also a telematics device for a motor vehicle with inputs for connecting sensors of the motor vehicle and with a transmitter for the transmission of sensor data.
  • the latter problem can be solved by setting up a traffic radio channel be fixed, the last traffic reports be stored in a memory and therefore at any time can be intercepted.
  • the store is organized so that newly arriving messages are the oldest stored Eliminate messages from memory (first-in-first-out).
  • This FCD procedure (Floating car data procedure) is used only for the determination of traffic jams and travel times and for the generation of Traffic reports. So that a corresponding traffic jam warning from the Central can be generated and sent out numerous current data from road users are evaluated, to be sure of the presence of a traffic jam to be able to close. This also means that the FCD clear system response time that occurs between the Occurrence of a jam and the generation of a corresponding Traffic jam warning passes. During this reaction time the Traffic jam enlarged by vehicles entering the dust area and the risk of accidents caused by traffic jams, especially rear-end collisions, not eliminated. Furthermore are other accident-prone circumstances in the known method not taken into account, such as local smoothing points due to black ice, traces of oil or similar
  • EP-A-0 627 719 discloses a device for Detection and warning of dangerous situations and accidents for use in motor vehicles.
  • the output signal of a speed sensor is constantly with a threshold value compared, whereby if the threshold is undershot, a radio signal indicating a hazard or indicates an accident situation is emitted.
  • This signal is from a receiver in the vehicle as well as in other vehicles in the area and serves as a warning the danger or accident situation.
  • the present invention is therefore based on the problem enable an even faster warning of road users, which also relates to dangerous situations that go beyond congestion can extend.
  • a method according to the invention is initially mentioned type characterized in that motor vehicles with receiving devices for the communicated data be equipped and that typically dangerous situations assignable sensor data on a short way from vehicle to vehicle transmitted and in the receiving motor vehicle to a warning signal are processed.
  • the inventive method is based on the fact that more modern Motor vehicles are already equipped with such an extensive sensor system are that the on-board created by the motor vehicle Sensor data already provides information about dangerous situations can give up if this data from vehicle to vehicle subsequent motor vehicles are transmitted.
  • the transmission of the signal of the crash sensor may be supplemented by a message transmitted hereby to subsequent vehicles naturally cause an effective warning of these vehicles and the occurrence of rear-end collisions caused by an accident Vehicles are reduced.
  • the same applies to one Breakdowns in a lane are vehicles that have remained In this case, the hazard warning lights are switched on regularly becomes.
  • the hazard lights can be switched on in the motor vehicle sensed and as a corresponding signal to subsequent Vehicles transmitted using vehicle-to-vehicle communication become.
  • a warning works in the same way Obstacles in lanes, for example by one of a load that has fallen on a truck is caused by the Output signal of a brake sensor, for example the activation the ABS control (stutter braking) senses and as a signal is transmitted for emergency braking.
  • ABS control sinutter braking
  • In the receiving vehicle can turn these signals into special warning signals optical and / or acoustic form and, if necessary, corresponding Ads processed on a display.
  • the invention therefore sensor signals in previous Vehicles are created for subsequent vehicles Driver warning available. This can already be a achieve an effective warning of special dangerous situations.
  • the preferred embodiment of the invention is therefore the motor vehicle equipped with an onboard intelligence that an evaluation of your own and / or received sensor data enables and generates its own warning message to the driver.
  • the outside temperature may drop below 0 ° C in connection with a transmitted signal for the Actuation of the light switch can be interpreted as that there is an increased risk of black ice, since the operation of the Light switch with great certainty on a reduced view is due to precipitation or fog. In In these cases, smoothness is very likely.
  • traffic information included be, for example, on a traffic radio channel in encoded, i.e. automatically evaluable form are broadcast.
  • a motor vehicle has its own and / or received sensor data together with position information transmits to a control center, which evaluates the sensor data and traffic warnings to road users connected to them sending out. It is possible to use the bare sensor data or the sensor data already pre-evaluated on board to transfer.
  • the head office can, for example, by a service provider be formed in a cellular network in which numerous Data on traffic and weather conditions arrive at the therefore an extensive evaluation and more reliable creation of traffic warning messages is possible.
  • an inventive telematics device of the type mentioned that is characterized by a receiving device for Reception of telematics equipment from other vehicles Sensor data and an evaluation device for emitting warning signals due to on-board and / or received sensor data.
  • the telematics device can in particular be used to connect a Crash sensor, an indicator for switching on the hazard warning lights and / or one that indicates an ABS regulation Brake sensor can be set up.
  • the telematics device can use sensor data as an evaluation device to evaluate numerous own and / or received sensor data and for generating and outputting one Warning message to the driver.
  • To the evaluation facility can be a memory for otherwise encoded Form received traffic information must be closed.
  • the telematics device is for participation in the FCD method at the same time for sending your own and / or received ones Sensor data or data generated from their evaluation on board Warning notices are formed together with position data at a central office.
  • the creation of traffic warnings by the central works even if only a certain part the road user is the one transmitted from vehicle to vehicle Forwards sensor data or warning messages to the control center.
  • the sensor data is forwarded to the control center preferably with the aid of a mobile radio transmission device, wherein preferably special standardized short messages for the Transmission of the sensor data can be used.
  • the transmission from vehicle to vehicle can be done with a transmitter with a short range of a few kilometers, so that all received sensor data are relevant as short-term can be classified. In this case, the transmission a position specification may be unnecessary. Otherwise it will be useful to locate the telematics device for the creation of position data for the Connect motor vehicle, so that with the sensor data associated current position data of the sending motor vehicle be transmitted. With the help of an appropriate location device in the received motor vehicle can then Distance to the emitting motor vehicle are determined, so that an estimation of the timeliness of the warning message is no problem can be done.
  • the single drawing figure shows a plurality of N sensors 1 connected to associated inputs of an interface device 2 are.
  • a Motor vehicle bus 3 connected via the also traffic-relevant Data can be communicated.
  • the interface device 2 is connected to an evaluation device 4 in which the sensor data of the sensors 1 checked for their relevance become. Relevant sensor data are sent via a transceiver 5 and an associated transmit / receive antenna 6 corresponding transmission / reception devices 5, 6 below Transfer vehicles. Accordingly, sensor data from others can also Motor vehicles via the transceiver 5 and their associated antenna 6 reach the evaluation device 4 and be evaluated with.
