Definitions

  • the invention relates to a data transmission device according to the preamble of claim 1, a system according to claim 5 and a method according to claim 8.
  • Data storage devices for transportation are e.g. in the form of driving data recorders (Black Box, Event Data Recorder, EDR, or Motor Vehicle Data Recorder, MVDR) known.
  • driving data recorders Black Box, Event Data Recorder, EDR, or Motor Vehicle Data Recorder, MVDR
  • a conventional EDR records sensor vehicle sensing data in a time window around a triggering event (e.g., accident). This happens u.a. in the case of later reconstruction of the conditions that led to this event.
  • a triggering event e.g., accident
  • the measurement data of a single vehicle with an EDR after evaluation can only give a limited picture of the triggering situation.
  • An example is the forensic determination of the cause of multiple collisions.
  • the correct evaluation is very complex.
  • EDRs record measured values over a defined time window before and after a triggering event either in the form of direct sensor data or in the form of preprocessed kinematic models in a mechanically protected storage medium.
  • cyclic recording methods are often used, the limited memory of which is repeatedly overwritten.
  • the oldest recorded data is replaced by new data.
  • time span on measured data in the local memory of the EDR.
  • Some known solutions allow the transmission of the measurements over a communication system (wireless or wired, e.g., also continuous) to a remote stationary evaluation component.
  • EDRs only record measured values of local sensors. Even if several records of different vehicles exist, they are without temporal and causal connection. In addition, a joint evaluation may fail due to the availability of not directly involved vehicles.
  • EDRs are basically incapable of providing sensor data of adjacent vehicles or surrounding - e.g. Sensor technology that has been realized via a roadside infrastructure and thus only provides a very limited view of the triggering event. Coupled events are therefore not detectable.
  • the data transmission device for cooperative data exchange between mobile objects, in particular vehicles at least one storage device for geographical data regarding the position of the object, the storage time, communication data, movement data of the object and / or state data of the object.
  • the communication process itself (time, content, sender, receiver, 7) is also stored, which serves as proof of the correct functioning of the communication system e.g. makes sense in determining the cause.
  • At least one parameter of the static and / or dynamic state of the at least one object can be detected.
  • These parameters may e.g. The operating and / or driving behavior of a vehicle or the parameters of the motion and / or environmental situation relate.
  • the data transmission device has at least one comparison means which automatically compares at least one of the parameters with at least one predetermined condition and generates a result data set as a function of this.
  • the result data set is generated as a result of the comparison at the time of the trigger event.
  • the data transmission device has a transmitting device for the automatic transmission of a signal data set as a function of the generation of the result data set, wherein the signal data record can be detected by an external mobile receiving device.
  • the signal data record is generated after generation of the result data record and transfer. It thus represents the transmitted trigger event.
  • the external receiving device can be, for example, a structurally identical data transmission device which is arranged on another vehicle.
  • the data transmission device thus enables the cooperative data exchange between different mobile objects, wherein the data exchange is triggered by a specific event, determined by the comparison means.
  • the cooperative data exchange takes place, for example, only when an external client requests the result data record via the data transmission device or when the generating vehicle sends it out without request
  • the transmitting device is designed as a wireless transmitter, in particular for wireless Internet connection. This enables a data connection between the mobile objects in a simple manner.
  • an embodiment of the data transmission device has a means for determining the exact time, position and / or kinematic data of the object.
  • the object is also achieved by a system that has a data transmission device according to the invention.
  • a system that has a data transmission device according to the invention.
  • at least two of the data transmission devices are arranged on or in two separate objects, with between the Data transmission devices at least temporarily a cooperative data connection exists.
  • the separation here can be a physical separation, not necessarily a spatial separation.
  • an overall data record from the result data sets of at least two objects is formed, which gives an overall view of the situation of all objects of the system.
  • the object is also achieved by a method for cooperative austauch according to claim 8.
  • FIG. 1 an embodiment of the system according to the invention using embodiments of the data transmission device 111, 112 is described in a schematic representation.
  • Two objects here two vehicles 101, 102, are each coupled to embodiments of the data transmission device 111, 112 according to the invention.
  • the data transmission devices 111, 112 are each arranged in small housings in the bodywork of the vehicles 101, 102.
  • the Data transfer devices 111, 112 are substantially identical, so that both can be described together. In principle, however, it is possible that the data transmission devices 111, 112 are structured differently.
  • Each of the data transmission devices 111, 112 has a sensor means 1, 2 for detecting at least one parameter of the static and / or dynamic state of the vehicle 101, 102.
  • a parameter relating to the static state can e.g. be a deformation of the vehicle after a collision.
  • a dynamic parameter may e.g. characterize the acceleration of the vehicle 101, 102.
  • the data transmission device 111, 112 has a comparison means 11, 12, with which the data determined by the sensor means 1, 2 with one or more, e.g. also blurred, pre-stored condition is automatically compared.
  • acceleration values are constantly measured by the first sensor means 1 of the first vehicle 101 and compared to a pre-stored acceleration value by means of the first comparison means 11. If the amount of the measured acceleration exceeds a specific threshold as a predetermined condition, which indicates a collision, the first comparison means 11 automatically generates a result data record 200 in which the data relevant for the assessment of the vehicle situation is contained.
  • the storage of a time marker is of particular importance so that the result data set 200 can be evaluated synchronized with other data sets.
  • the position (possibly determined by a GPS system) can be stored, whereby GPS systems provide high-precision time information, so that a coupled storage of time and position is possible.
  • the data transmission device 101 Since the data transmission device 101 operates with a defined time window, the last acceleration values, the last speed values, data relating to the braking actions (eg information about blocking wheels from the ABS system) and steering positions are also stored in the result data set 200. It is also possible to store acoustic or biometric data (eg data on the driver's waking state) from inside the vehicle. Furthermore, it is useful for unique assignment of the result data set 200 to integrate a certificate of authenticity that uniquely identifies the vehicle 101 and ensures the integrity of the result data record 200. This can also be done in conjunction with an occupant identification.
  • acoustic or biometric data eg data on the driver's waking state
  • the result data set 200 is automatically stored in a first memory means 41 of the first data transmission device 111.
  • a first data transmission record 201 is automatically generated by a first transmission device 21, which signal is detectable by an external receiver device 32 of a second data transmission device 112 of a second vehicle 102.
  • This signal data set 201 automatically triggers an action in the second data transmission device 112 which depends on the content of the signal data record 201.
  • the signal data set 201 includes the result data set 200
  • the data of the result set of the first vehicle 101 is automatically stored in the second memory means 42 of the second vehicle 102. Even if the first vehicle 101 were completely destroyed, a copy of the last kinematic data of the first vehicle 101 would be stored in the second vehicle 102. This would be the reconstruction facilitate the collision of the first vehicle 101. It should be noted that the second vehicle 102 need not be involved in the collision.
  • first vehicle 101 can also exchange data with more than one vehicle, and that alternately.
  • the signal data record 201 may also or only additionally represent a warning signal that warns the driver of the second vehicle 102 of a dangerous situation.
  • the data transmission devices 111, 112 represent an extension of the function of conventional driving data recorders in the direction of a distributed driving data recorder for cooperative, communicating vehicles 101, 102.
  • the embodiment described here for simplicity on the basis of two vehicles 101, 102 is an arbitrary number of vehicles 101 , 102, wherein the vehicles 101, 102 basically do not have to have the same structure.
  • the described cooperative approach assumes that indirectly or directly networked vehicles 101, 102 can also communicate directly with vehicles 101, 102 in their spatial environment and, for example, can also have an internet connection.
  • Such communication systems Car-to-Car Communication Systems, C2CC, or Dedicated Short Range Communications, DSRC
  • C2CC Car-to-Car Communication Systems
  • DSRC Dedicated Short Range Communications
  • the distributed realization is described by the fact that the complete information about the static and / or dynamic information is distributed decentrally over a number of vehicles 101, 102, ie in the form of many temporally and spatially balanced ones Result data sets in the individual vehicles as each locally stored partial information is present (eg as part of the total data set.) Individual data sets can also have temporal and / or spatial offset, so that "different viewing angles" are possible.
  • the approach is suitable on the one hand for redundant storage and thus for the detection of manipulations or for the reconstruction of missing or destroyed data.
  • causes can also be detected that are themselves in the communication between vehicles 101, 102 - e.g. in the faulty transmission or evaluation of information transmitted by or via other vehicles 101, 102, as this information may possibly be among the triggering factors of the event.
  • the approach is basically not dependent on the existence of an environment of networked vehicles 101, 102.
  • a "triggering pulse” ie a signal data set 200
  • this can also be done wirelessly by infrared or radar pulses and does not necessarily require a sophisticated communication infrastructure.
  • a cooperative EDR (Cooperative Event Data Recorder, CEDR) consists of an EDR of conventional design which additionally has a data transmission device 111, 112 for transmitting the recorded data to a storage means 41, 42 (background storage) and a control means (sensor means 1, 2; 11, 12; transmitting device 21, 22) for Triggering this transmission has.
  • the records 200 and 201 already contain this signature.
  • the receiving vehicle can not create this certificate only extend (for example, by its own position and by a reception timestamp)
  • the data transmission devices 111, 112 are connected to a wireless transmission device 21, 22, so that an external triggering event (signal data set 201) on the one hand can initiate the transmission of the recorded data into the memory means 41, 42, as well as authorized points allow either the reading of the data or can initiate the transfer of the data to authorized agencies.
  • the connection within the data transmission device 111, 112 to the transmitting device 21, 22 can likewise be carried out wirelessly.
  • All described components may be implemented separately (locally distributed) or in a single closed system. Likewise, the storage means 41, 42 may be present several times.
  • the distributed cooperative approach assumes that, in the event of a triggering event, the affected first vehicle 101 will send out a short message to the surrounding vehicles, here only the second vehicle 102, causing it to sign a signed copy of the vehicle recorded up to that time Data - or within a given time window, including future data - copy their own EDR into the local, protected background storage (snapshot).
  • the recording may also include information about the communication activity that existed before, after, or in connection with the event.
  • the recorded data may also include information about the particular environment of the recording vehicles as well as the communication activity between these vehicles (advanced EDR, enhanced EDR).
  • the transmitted message (signal data record 201), which is used to trigger the recording, on the one hand can act as a dedicated control command triggering the recording immediately.
  • the regular information exchange of a C2CC system e.g. by the evaluation of a warning message (hazard warning) - are used.
  • Possible effects of the signal data set 201 are shown schematically in FIG. 2, the terms being explained below.
  • Evaluation of the recorded data of all participating vehicles 101, 102 thus provides a complete picture of the situation before and immediately after the triggering event for the entire group of vehicles 101, 102. This method leads to a result even if directly affected vehicles, 101, 102 can make no contribution to the event evaluation due to extensive damage or manipulation.
  • these received data can be recorded passively in conjunction with local sensor data and, on the other hand, actively used by local decision logic to transfer the existing recording to the background memory (remote trigger, CEDR trigger).
  • the deletion of the stored result data records 200 can take place either directly as a result of the transmission of the data or indirectly through one or more external events. This includes manual deletion (by an authorized agency) and automatic deletion by time-lapse.
  • the benefit of a data transmission device 111, 112 according to the invention lies in obtaining information in complex situations in which the cause and course of a triggering event can not be determined solely on the basis of the information present in the vehicles directly concerned or in the simplification of this process or to improve the accuracy this process.
  • a data transmission device (CEDR) 111, 112 can be used to analyze situations in which a malfunction of other vehicles 101, 102 or of the communication system has been or is suspected in cooperative systems.
  • a CEDR thus represents the technical equivalent of an independent observer of the complex process of a fault.
  • An embodiment of the inventive CEDR 111, 112 can be realized as a stand-alone device or, with the exception of the sensor system, as a software component within or in conjunction with the communication system of the vehicle 101, 102.
  • An existing EDR can also be used if it already has an interface for reading out the data, for example by means of evaluation electronics. The prerequisite for this is that the reading process does not disturb the regular recording operation of the EDR.
  • a data transmission device 101, 102 can be achieved in conjunction with a C2CC system.
  • the communication system already implements part of the required functionality.
  • the retrieval of stored records may be done in a manner in which an authorized location - e.g. Authorities and Organizations with Backup Tasks - use available communication paths to individual vehicles to request that stored records created at or near a given location at a given time be made known.
  • an authorized location e.g. authorities and Organizations with Backup Tasks - use available communication paths to individual vehicles to request that stored records created at or near a given location at a given time be made known.
  • An effective possibility of the query can be realized if vehicles have an Internet connection. This can be realized via a cellular connection (GSM / UMTS), via IP Datacast (DVB-T) or via a DSRC or C2CC system.
  • GSM Global System for Mobile communications
  • DVD-T IP Datacast
  • C2CC C2CC
  • CEDR An important application of the CEDR is its potential use as an accident data recorder, as described in connection with FIG.
  • the triggering event is then, for example, the sensory detection of an impact, the triggering of the airbag of the affected vehicle, the triggering of the airbag of an adjacent vehicle or emergency messages of adjacent or short distance vehicles.
  • the storage of the data is triggered by a message from the directly involved vehicles 101 to surrounding vehicles 102 via a C2CC system.
  • the data is transmitted from the first vehicle 101 to a plurality of second vehicles 102.
  • All adjacent vehicles 102 having CEDR equipment and receiving this message will initiate the storage of their local communication device 112.
  • the data to be stored here would be, for example, the time of triggering, the identity of the triggering vehicle, the position and speed of the adjacent vehicles and the vehicles exchanged in the run-up to the accident Messages in question. If the directly involved vehicles are able to send actively relevant data via the communication system - eg acceleration values - these should also be recorded.
  • the storing vehicles After occurrence of the event, the storing vehicles will usually move away from the location of the event - only directly involved vehicles remain.
