Definitions

  • the invention relates to a method for transmitting data between individual vehicles in a localized environment via an information network.
  • Such information networks are currently under development in order to enable communication or data exchange between mobile stations, in particular between vehicles.
  • state data relating to individual vehicles such as However, the vehicle position and speed, the direction of travel and the planned route, are also transmitted situation-related data such. the occurrence of a traffic jam or the current parking situation at certain locations.
  • situation-related data such as the occurrence of a traffic jam or the current parking situation at certain locations.
  • driver assistance systems try to reduce this risk through targeted driver assistance.
  • certain aspects of the driver's condition such as fatigue, attention, stress, emotions, etc., as critical parameters in the activation and even in the functional design of a driver assistance system.
  • driver can also be signaled, for example, his own lack of responsiveness.
  • driver assistance systems can reduce the risk of a driver's misconduct of a suitably equipped vehicle, they do not affect the driving behavior of the other road users.
  • a GSM network is known via which traffic information can be transmitted between vehicles.
  • states such as acceleration, braking, light operation or windscreen wiper operation are transmitted.
  • a vehicle safety system in which a health condition of a driver is monitored. If the driver is no longer able to control the vehicle, acoustic or optical radio signals are output. If necessary, an emergency call is sent by radio.
  • the accident risk can be significantly reduced if the driver assistance system of a vehicle not only has state data of its own driver, but can also take into account state data of the drivers located in the environment.
  • an information network with which data can be transmitted between individual vehicles in a locally limited environment, for the exchange of driver status information.
  • an information network then provides each vehicle or its driver with information about the condition of the remaining drivers in a locally limited area. This allows potential dangerous situations, which are caused by other drivers, to be detected faster and better.
  • the driver status information which can be obtained in the most diverse ways and with the most diverse means, must be processed on the transmitter side.
  • Another aspect of the data exchange according to the invention is the dispatch and the u.U. Targeted distribution of driver status information to other vehicles.
  • the transmitted data must also be provided or processed on the receiver side.
  • the driver's condition is usually influenced by several factors. For example, the driver's attention is not only affected by fatigue, but also by other vehicle systems such as the telephone and the navigation system. Therefore, in an advantageous variant of the invention, data on various aspects of the driving state are detected and also exchanged.
  • the meaningfulness of the resulting description of the condition can be additionally increased by bundling the information over a defined period of time, such as an averaging or also by specifying the minimum or maximum value determined during this period. In this context, it proves to be advantageous to transform the information obtained on the individual aspects of the driver state transmitter side into a single data format.
  • the driver status information is connected to further information about the vehicle and transmitted together with this vehicle information via the information network.
  • This vehicle information can then also be advantageously evaluated by the driver assistance system to detect dangerous situations early on.
  • information about the current position and speed of the vehicle, about the direction of travel and / or the planned vehicle route can be transmitted.
  • the driver assistance system of a receiving vehicle can estimate relatively reliably whether an encounter with the transmitting vehicle is imminent and consequently the driving behavior of the driver of the transmitting vehicle has to be considered.
  • the relevant receiver vehicles for a sending vehicle can also be determined, e.g. Oncoming vehicles and vehicles on the same lane, with the same direction of travel, etc ..
  • the driver state information is then made available only to these receiver vehicles.
  • An appropriate distribution or dispatch of the driver status information can be ensured, for example, by limiting the range or performance of the information transmission, so that only receivers in the immediate vicinity of the transmitter can receive the transmitted information.
  • the receiver vehicles relevant for a sending vehicle can be determined.
  • the driver status information can be exchanged directly between the vehicles.
  • the information transmission can also take place via a relay server station. This proves to be advantageous in particular when the driver status information is targeted only at receiver vehicles determined to be relevant to be distributed.
  • the relay server station then evaluates the information about its position, speed, direction of travel, etc. transmitted by the individual vehicles in a permanent or timed manner, and then determines the respective addressees for the received driver status information. For example, by means of a suitable coding, this driver status information can then be selectively made available only to the relevant receiver vehicles.
  • the driver status information is made available only to selected receiver vehicles that are deemed to be relevant, it should first be checked on the receiver side whether this information is relevant for the receiver vehicle in the current driving situation. For this, the received driver status information must be provided on the receiver side, i. H. be prepared for the corresponding system of the recipient vehicle. This may include the extraction of the driver status information from the other received information as well as the transformation of the received data formats in the necessary formats based on their own system. Only then can the received driver status information be evaluated.
  • the single FIGURE is a block diagram illustrating the exchange of driver status information between two vehicles in a localized environment.
  • Each of the two blocks 10 and 20 shown in the single figure represents a vehicle in a localized environment, the vehicles 10 and 20 acting as mobile transmitting and receiving stations of an information network with which data can be transmitted between the individual stations.
  • the information network shown here further comprises a relay server station 30, which is usually arranged stationary but can also be mobile.
  • the information network shown here is used to exchange driver status information.
  • the block diagram of the single figure is intended to illustrate the measures required.
  • information 1 relating to various aspects of the driver's condition is detected.
  • This collection of biometric data can be done by a variety of technical means, such as e.g. by measuring muscle activity or skin resistance of the driver.
  • Certain aspects of the driver's condition, such as its stress can also be derived from certain vehicle data, such as Derive the current vehicle speed and / or activation other systems in the vehicle, such as the telephone handsfree or the navigation system.
  • this driver status information is supplemented by additional vehicle-related information 2.
  • vehicle-related information 2 may be the technical data of the vehicle and also currently detected vehicle information, such as vehicle information. the vehicle position and speed.
  • Both the driver status information 1 and the additional information 2 are supplied to an in-progress preparation 3, where they are transformed into a uniform data format.
  • an in-progress preparation 3 where they are transformed into a uniform data format.
  • different aspects of the driver's condition can be summarized over a defined period of time and possibly classified.
  • the information processed in this way can then be sent, for which purpose the two vehicles 10 and 20 are equipped with a corresponding transmitting device 4.
  • the information of the two vehicles 10 and 20 transmitted directly to the respective other vehicle 20 and 10, which is indicated by the arrows 11 and 21.
  • the information of the two vehicles 10 and 20 are each still transmitted to the relay server station 30, which is illustrated by the arrows 12 and 22.
  • the relay server station then distributes the received information to the respective addressees, which is illustrated by means of the arrows 31 and 32. Does the information network cover more than just two vehicles, i. If there are more than two vehicles in a localized area, the relevant addressees for the information transmitted by a vehicle can be determined on the basis of the vehicle information transmitted by the other vehicles, such as current vehicle position, speed and direction.
  • the relay server station 30 can then selectively forward the information received from a vehicle only to certain vehicles, for example, only to vehicles that are on the same lane as the sending vehicle.
  • the two vehicles 10 and 20 also each have a receiving device 6 for receiving the information emitted by other vehicles information.
  • the received information is supplied to information processing 7, where it can be transformed, for example, into a data format suitable for the system of the receiving vehicle.
  • the data that can be evaluated in the system of the receiving vehicle can be extracted and evaluated here.
  • the received driver status information is also evaluated.
  • the result of this information processing 7 is then provided at 8.
  • the received driver state information is linked to the information 1 about the state of the driver, which is indicated by the arrows 13 and 23.
  • the invention concerns the general processing, distribution and dispatch as well as the reception, processing and provision of information on all manifestations of the driver state so that whenever possible in each vehicle in a locally limited area information for Driver status of the relevant other vehicles in this area are available.
  • driver state information of other vehicles can be used to warn the driver of the receiving vehicle explicitly against specific hazards. For example, a driver approaching an intersection can be warned ahead of time of a vehicle that is also approaching that intersection from another direction if its driver is particularly inattentive.
  • the received driver status information can also be evaluated by the driver assistance system of the receiving vehicle in order, for example, to take into account the tiredness of the driver of the preceding vehicle during the automatic triggering of preventive measures.
  • the ACC could automatically choose a larger time gap here.
