Definitions

  • the invention relates to a method for creating warning notices for drivers of a motor vehicle using Sensor data from at least one participating in traffic Motor vehicle.
  • the invention further relates to a traffic warning device for a motor vehicle to issue warning notices the driver.
  • 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).
  • This FCD (Floating Car Data) process is used exclusively for the detection of traffic congestion and for the generation of Traffic jam reports and for determining and evaluating travel times.
  • a corresponding traffic jam warning from the head office numerous can be generated and sent current data from road users are evaluated in order with the necessary security for the presence of a traffic jam to be able to close.
  • This also applies to the FCD procedure a significant system response time occur that between the occurrence of a jam and the generation of one corresponding traffic jam warning passes. During this response time the traffic jam is caused by entering the dust area Vehicles magnified and the risk of through the Accidents caused by traffic jams, especially rear-end collisions, not eliminated.
  • other accident-prone circumstances are not taken into account, such as local smoothing points due to black ice, traces of oil etc.
  • the present invention addresses the problem that Creation of warnings for the driver of a motor vehicle still speed up.
  • the respective sensor data is transmitted via the method from vehicle to vehicle instead and there will be warnings evaluating the sensor data created in other vehicles and the on-board sensor data created and output.
  • the method according to the invention is based on the knowledge that in modern motor vehicles already so many sensors are available or easy to implement are whose output signals are more relevant for the assessment of traffic Situations that can be used are an evaluation in the vehicle to create relevant warnings is possible for the driver.
  • sensors already present in many vehicles of this type are temperature sensors for the outside temperature, Slip sensor of an ABS control or a traction control, Light switch, hazard warning light switch, crash sensor of an airbag, rain / moisture sensor of a wiper control etc.
  • the evaluation of the sensor data, the on-board and the received sensor data is included otherwise received and stored traffic-relevant Information made.
  • traffic-relevant Information can for example via a traffic radio channel received by a car radio and stored in a memory for current traffic reports and if necessary also passed from vehicle to vehicle.
  • the traffic warning device a receiving device for receiving other motor vehicles emitted sensor data by the Evaluation device for forming warning notices preferably evaluated in connection with the on-board sensor data become.
  • the receiving device is expedient at the same time as a sending device for sending your own sensor data to other vehicles.
  • the traffic warning device also has one Evaluation device connected receiving device for traffic-relevant messages in a mathematically evaluable form on, for example, by receiving broadcasts Traffic reports via a separate traffic radio channel, which are preferably in a known protocol, for example sent out according to the Alert-C protocol and accordingly can be evaluated in the receiver.
  • the location may not be necessary.
  • a satellite-based position determination such as in particular is contained in motor vehicle location systems.
  • the location is in a localization code like it is provided in the Alert-C protocol, transferred and then with the corresponding localization codes in the broadcast traffic reports comparable.
  • the warnings can be output visually and / or acoustically, but also tactile, for example in the form of vibrations of the Steering wheel, are issued.
  • output signals come from N sensors 1 to an interface device 2, which is also connected to a Motor vehicle bus 3 is connected, on which a data exchange between actuators and sensors of the motor vehicle and consequently also relevant for the traffic situation Information can be transmitted by the Interface device 2 can be detected.
  • Additional Information 4 can, for example, from a GPS module for position determination his.
  • Sensor data and information reach an evaluation level 5, the sensor data with predetermined algorithms sensors 1 and the other information from FIGS. 3 and 4 evaluates and from this generated warnings in an output device 6 acoustically with a loudspeaker 7 and / or are optically output with a display device 8.
  • the received sensor data and other received data Information 4 can be stored in a memory 11 and then be used for further evaluation.
  • the additional Information 4 can have its own antenna or can also be received via the antenna 9, if this as a "multi-signal" antenna is trained.
  • An example of an evaluation and generation a warning message using the sensor data of the on-board Sensors 1 can result from the fact that the sensor signals an outside temperature sensor, a rain / humidity sensor and a traction slip sensor indicate that the outside temperature is below 0 ° C, that it is raining and that a drive slip occurs.
  • the warning signal can be derived from this that there is slippery road.
  • a combination of sensor data from a vehicle in front and on-board sensor data enables a warning for example in the following case:
  • a vehicle in front is at location A and reports the sensor data about precipitation, temperature, time etc.
  • the evaluation facility 5 can using the stored information about location A and your own sensor data when approaching to location A the warning message "Danger of slippery roads" output.
  • Your own sensor data can in turn be transferred to other vehicles are transmitted so that this is also a warning can produce.
  • hazard reports without Time delay generated in the vehicle and output to the driver become. It can link acute information through the local sensor data with a previously in memory 11 stored knowledge and combining new ones Messages are generated that are output to the driver and may be transferred to other vehicles or a control center, thus quick warnings to other road users be available.
