Definitions

  • the invention relates to a method for recording tachograph data of a vehicle with the preamble features of claim 1 and a tachograph or a communication system for carrying out such a method.
  • This system has serious disadvantages in that images taken by a camera or image sequences are only stored within the vehicle. In the event of an accident involving a driver's escape, it is necessary for the collision partner to establish such a system that the vehicle's mark of sufficient quality is recorded on one of the images. However, this is only the case when the receiving camera is directed towards the other vehicle so that its license plate can be recorded. Another problem with such systems is that the saved data is stored within the receiving vehicle. As a data manipulation can not be completely ruled out, such data are therefore only conditionally usable as evidence.
  • a system is known by the term telematics, which allows the exchange of information between motor vehicles.
  • the data exchange between two vehicles or a vehicle and a stationary station takes place via a radio interface.
  • Telematics will increasingly become a component of automotive equipment.
  • Vehicle drivers can receive general or safety-related information during a car trip, for example, about road conditions, traffic jams or city maps of the current destination.
  • the transmission of other relevant for the driver information is possible.
  • infotainment is therefore in particular the so-called infotainment, so the supply of current information, important.
  • DE 433 8556 discloses a device in a vehicle for recording travel route information.
  • WO 98/15922 A a navigation system is known, which stores data about the states of motion of a motor vehicle, for example in a motor vehicle's internal travel or accident data recorder.
  • EP-A-0 782 118 For example, a navigation system is known which informs the driver of the vehicle about the next action, depending on whether or not he correctly follows the proposed route.
  • the object of the invention is to improve a method and a device for recording tachograph data or driving parameters of a vehicle.
  • the transmission of tachograph data of a vehicle via a radio interface to a storage device separate from the vehicle offers particular advantages in the case of an accident proof in the event of an accident.
  • the stored data can not be destroyed by the accident itself, such as a tachograph sheet of paper in a fire caused by the accident, nor can the Tachograph data in the external memory to be subsequently manipulated.
  • the relevant data for the tachograph not only transmitted via a radio interface to another device, but also stored in a remote memory.
  • a remote memory can be arranged both in a stationary station along a route of a vehicle and in a more distant central computer of a communication network or a foreign network connected to the stationary station.
  • the data is exchanged via a radio interface of a cellular radio communication system, for example in accordance with the GSM standard or the UMTS, a radio data network, for example in accordance with the Hiper-LAN standard, or a radio ad hoc network.
  • a radio interface of a cellular radio communication system for example in accordance with the GSM standard or the UMTS
  • a radio data network for example in accordance with the Hiper-LAN standard
  • a radio ad hoc network for example in accordance with the Hiper-LAN standard
  • the possibility of transmission advantageously also exists in more remote regions, in which cellular or regional radio networks are not provided or are provided only with insufficient coverage.
  • instantaneous location or position data can be stored, which can be determined for example by means of GPS.
  • acoustic and / or optical data can be recorded and recorded, as well as data from various other sensor devices for determining the respective instantaneous distance to other objects.
  • the data acquisition takes place during vehicle operation, which of course also includes parking in a parking lot compared to the stand in a workshop.
  • the data is advantageously cyclically overwritten or deleted.
  • a record of the last cyclic sequence is automatically saved or at least not overwritten or not deleted.
  • the recording of the data can be activated or saved even after the transmission or the failure of a security signal.
  • the transmission of such a backup signal is particularly important in a remote recording to prevent overwriting the data after an accident.
  • a backup signal can be transmitted continuously to cause storage of the data, after the elimination of the backup signal by, for example, an accident further data storage and in particular further data overwriting or data deletion is automatically stopped.
  • Fig. 1 how out Fig. 1 can be seen, a plurality of vehicles A1, A2, A3 mobile stations MS1, MS2, MS3, which allow communication via radio interfaces V1, V2 with each other. Also possible is the communication of the mobile stations MS2 with fixed stations BS via corresponding radio interfaces VB.
  • Such stationary stations BS can be completely independent stations of a so-called ad-hoc network, but can also form radio stations of a network.
  • a radio communication system is also possible, for example in accordance with the GSM or UMTS standard (GSM: Global System for Mobile Communication; UMTS: Universal Mobile Telecommunication System).
  • GSM Global System for Mobile Communication
  • UMTS Universal Mobile Telecommunication System
  • radio communication networks and radio-based data networks can be used.
  • the data exchange between the individual stations MS1, MS2, MS3, BS can take place via circuit-switched or packet-oriented connections.
  • the exchange of information via, for example, text messages SMS (Short Message System) is possible.
  • SMS Short Message System
  • WAP radio-based application protocols
  • URL Internet address
  • ad hoc networks offer particular advantages if, for example, after an accident, the following traffic or the surrounding traffic should be informed of this accident to allow other drivers a timely braking.
  • each have a complex line structure between two participants must be in order to subsequently transmit information from one participant to one or more other participants can offer ad hoc networks the possibility of direct information transfer to other participants or stations in the transmission area .
  • the information on ad-hoc networks can be more or less directly exchanged between the stations involved. This allows in particular faster reactions of subsequent vehicles to a preceding accident. In particular, a transmission over several intermediate stations is possible.
  • one or more memory devices M are provided throughout the system.
  • these driving-relevant parameters of one or more vehicles A1, A2, A3 are stored. This makes it possible to read out the recorded data at a later time in order to be able to determine, for example, an accident cause or an accident causer. If the storage takes place at a location or secure storage SM which can not be accessed by the parties involved, the data can advantageously also be used as evidence in court.
  • a mobile station MS1 with a control device C for controlling the data exchange and the radio interface and with a memory M for storing operating parameters for radio operation.
  • the connection of controller C and memory M can be done via a direct connection or a bus BUS.
  • Other devices can also be connected to such a bus, such as a switch for activating the horn L of the vehicle, which enables activation of the system when the horn is actuated, a camera P for recording individual or subsequent images and a multiplicity of sensor devices S.
  • such sensor devices S can be devices for determining and detecting parameters, for example the distance to surrounding objects, or for triggering an action, for example acceleration sensors or the like, to detect an accident and corresponding instructions for starting a transmission of data or a fixed storage of To trigger data.
  • recordable parameters are, in particular, distances to other objects or vehicles, the speed or acceleration of one's own vehicle as well as relative speeds or relative accelerations with respect to other objects.
  • sounds can also be recorded in order to subsequently detect acoustic warning signals that have been emitted by the vehicle driver or that may even have been overheard.
  • GPS devices GPS: Global Positioning System
  • the distance to another vehicle can be done either by corresponding distance sensors with, for example, sonar function or by the exchange of position data between two vehicles via the radio interface V1 and V2 between them.
  • Corresponding devices are advantageously located in each vehicle but are not required in every vehicle for the simplest embodiment.
  • a data exchange to stationary stations BS via corresponding radio interfaces VB possible.
  • such fixed stations BS can consist of a pure receiving device, a control device C and a memory device M.
  • data transmitted to this stationary station BS can advantageously also be stored in the memory device M.
  • the storage of the various data determined by the vehicle devices L, P, S within the vehicle in the vehicle memory M is advantageous, such external storage in the memory M of the base station or stationary station BS offers the advantage that this data is provided by the vehicle driver can not be manipulated at a later date and can therefore be used for evidence purposes.
  • transmitters for active data exchange with passing vehicles and sensor devices S or camera devices P can also be arranged at the fixed station BS in order to enable the detection of data of various kinds even at such stations.
  • such a stationary station also has an interface to a data network with further such stations or the Internet IP.
  • stationary station BS can be used, on the one hand, for the general supply of general information to passing vehicles and, on the other hand, also for forwarding data which the stationary station has received from vehicles to a central device within the network IP.
  • a secure Memory SM may be set up in the general traffic-related data for preserving evidence or for preparing various statistics can be stored.
  • the data exchange between two vehicles can advantageously be optionally controlled as a function of current operating conditions.
  • the information exchange can also be increased if the speed of the vehicle is above certain threshold values or an excessively negative acceleration at z. B. a full braking is detected.
  • identifying data may be, for example, a registered identification number, the official license plate or an access number of the mobile station MS1, MS2, MS3, e.g. For example, their assigned IP address.
  • identification data relating to the vehicle driver can also be stored.
  • Corresponding personal data can be provided by using a personal key in conjunction with a corresponding reader, an input of a codeword via a keyboard or an input by means of a magnetic card reader.
  • data can also be transmitted via any other interface, eg. As infrared interface or cable-bound interface, are read out of the vehicle-based communication system.
  • the data recorded in a vehicle is buffered cyclically in its memory M and is transmitted to an external memory via the radio interface only in the case of a predetermined event.
  • a predetermined event for example, an accident detected by acceleration sensors or an undershot minimum distance to another object can be defined.
  • a corresponding trigger signal can be transmitted to the external device, for example, a fixed storage in the last Seconds recorded data.
  • a trigger signal can be carried out either by a targeted command of the driver via a corresponding signaling button or automatically detected in certain critical driving situations signals of an acceleration sensor or the like.
