Definitions

  • the invention relates to a warning system in motor vehicles with the in the preamble of claim 1 specified features.
  • Such systems can be used manually or automatically triggered vehicle-to-vehicle communication take place to ensure road safety increase. Is a vehicle in a certain traffic situation (Accident, traffic jam, heavy braking, airbag deployment etc.), it sends out signals from other vehicles are receivable in the area. There are certain Motor vehicle functions such as optical / acoustic Displays or even automatic brake interventions depending on the reception initiated.
  • the field strength the received signals are evaluated in the receiving vehicle, from which conclusions about the distance to the sending location are to be drawn.
  • this is very buggy because the reception field strength clearly from external boundary conditions how weather, construction, etc. depends. That's how it is possible that the receiving field strength in the receiving vehicle temporarily decreases despite approaching the broadcast vehicle. A distance estimate is only very imprecise possible.
  • DE-PS 44 21 960 proposes the accident position, which is determined using a GPS system, in insert the transmission signal. This is very large amounts of data to transmit, and a receiving vehicle must also be equipped with GPS to be able to calculate how the relative position to the broadcast vehicle is. This system is very complex overall.
  • the invention is characterized Warning system by the specified in claim 1 Characteristics. Details of the invention follow from claims 2 to 4 and the following description.
  • Motor vehicles are equipped with a warning system for vehicle-to-vehicle communication equipped, the warning system as is known as the essential components of a transmitter and includes a receiver in the vehicle.
  • the warning system equipped vehicle may depend on traffic situation function as a sending vehicle or a receiving vehicle.
  • Vehicles are referred to as broadcast vehicles whose transmitters send out warning signals.
  • reception vehicles are the vehicles that receive the warning signals.
  • a transmitter of a vehicle is switched turned on when certain traffic situations the warning of the surrounding road users is required do. For example, these situations be: Acute braking maneuvers, airbag deployments, switching on the hazard warning lights or falling below certain (low) limit speeds.
  • these situations be: Acute braking maneuvers, airbag deployments, switching on the hazard warning lights or falling below certain (low) limit speeds.
  • About the Receivers receive vehicles in the vicinity of the broadcast vehicle the signals and these become an evaluation device fed.
  • the signals are analyzed there with the aim of estimating the distance between transmit and Receiving vehicle. Depending on the result of the estimate become motor vehicle functions in the receiving vehicle affected.
  • optical, acoustic or controlled haptic display elements so that the driver of the receiving vehicle on the dangerous situation becomes attentive and adapt his driving style can.
  • a far-reaching influence on the motor vehicle functions can by automatic cruise control or Brake control can be made if the result of Signal analysis a very close source of danger was recognized.
  • the broadcast vehicle will have various calibration signals with differentiated transmission power sending out.
  • one is between two and ten specified number of calibration signals sent out from a numerical code increasing with increasing transmission power consist. Because the analysis of the reception field strength buggy in terms of distance from the transmitter , it can at least be determined with certainty whether one approaches or approaches the broadcast vehicle away and whether you are in the closer or wider area of the broadcast vehicle.
  • FIG. 1 several vehicles are shown schematically on different roads and are shown driving in different directions, vehicles equipped with the warning system according to the invention being shown in black and vehicles not equipped in white.
  • vehicles 1, 2 are in an accident situation and vehicle 3 is forced to brake sharply or has already stopped.
  • a switching device of the vehicle 3 switches on a transmitter of the vehicle 3, whereby this vehicle 3 becomes a transmitting vehicle in the sense described above.
  • the transmitting vehicle 3 sends out various calibration signals I to V with different transmitting powers (arrows in FIG. 1).
  • the transmission power with which the calibration signals I to V are emitted is graded uniformly, and the range of these signals I to V is illustrated in the figures by dash-dotted lines 4 to 8.
  • the range of the calibration signals increases from signal to signal by approximately 100 to 200 m, so that the calibration signal V with the strongest transmission power (line 8) can be received from the transmission vehicle 3 in approximately 500 to 1000 m.
  • the calibration signals I to V themselves preferably consist of number codes, which become larger with increasing transmission power. For example, the following are sent out: calibration Transmission range Coded one - I 150 m Coded two - II 300 m Coded three - III 450 m Coded Four - IV 600 m Coded five - V 750 m
  • All vehicles 9 to 14 are equipped with warning systems and, as they are within range of vehicle 3 the trigger message including the Receive calibration signals (I to V). This makes everyone Vehicle 9 to 14 warned and informed about the now following calibration. Are in with very little effort Evaluation devices of the receiving vehicles the recorded Evaluate calibration signals, resulting in quick information to derive about the location of the emergency are.
  • the vehicles 11 and 13 receive two calibration signals V and IV.
  • the luminous intensity of the warning light compared to the light intensity of the warning light in the vehicle 14 can be increased. If the warning system cyclically Signal reception switches or a cyclical signal evaluation the cycle time for these vehicles 11 and 13 can be shortened.
  • the vehicle 13 is on the move in the transmission range (line 6) of the calibration signal III retract, whereas the vehicle 11 the transmission range (Line 7) of the calibration signal IV leaves.
  • comparing two successive groups of received signals takes the number of receivable calibration signals in the vehicle 13 from two to three and in vehicle 11 from two on one.
  • the warning in the vehicle 11 are canceled, whereas in the vehicle 13 increased attention is required.
  • three calibration signals are received V, IV and III in vehicle 13 should be the driver receive clear indications. In addition to the optical An acoustic warning should appear on the display become.
  • the vehicle 12 is also in a zone in of the three calibration signals V, IV, III can be received. However, this number changes over a longer period Route, and the warning given there can be parked when crossing line 6.
  • the most important thing is the function of the warning system for the Vehicle 10 that is in the immediate vicinity of the accident retracts.
  • the receiver of vehicle 10 is increasingly receiving more calibration signals and is in an area in which four calibration signals V, IV, III, II can be received are.
  • the automatic one Influencing the vehicle speed can be an appropriate one Show measure to prevent accidents. No later than when crossing line 4, i.e. when everyone is received five calibration signals V to I, the speed should be throttled.
  • the switching device of the vehicle 10 activate the transmitter and this vehicle 10 itself becomes the broadcast vehicle 10. For the vehicle 9 this does not apply or only for a short time, as this Vehicle 9 after passing the accident site near the accident Leaves the area without the switching device Transmitter activated.
