Abstract

The invention relates to data processing of vehicle-to-X messages. Data preprocessing takes place before the preprocessed data is transferred to the corresponding applications in the vehicle. In preprocessing, a data reduction can be performed. It is also possible to carry out a plausibility check and, if appropriate, a correction of the data before they are passed on to a security application, for example. In particular, the received data can be divided into different data classes that are treated differently.

In this way For example, an early data reduction can be performed become. For example, any equivalent application will not always be supplied with all data coming in via the radio channel, but only with a specific selection of the received data. Conversely, this means that not every application can be used simultaneously must be able to deal with all data and all the received data. This exam and the data selection may be upstream in the data pre-processing unit occur.
  • In C2X communication, very large amounts of data may be required, for example, in the range of 12 Mbits of raw data IEEE 802.11p , These data may be reduced by preprocessing into an amount that is manageable for a subscriber's security system or mobility systems (eg by not forwarding inappropriate data to that system). Furthermore, the preprocessing, especially for security systems, can maintain a level of trust or a security level of the data.

  • According to a further embodiment of the invention, the data pre-processing unit 105 for identification of different data classes (of the received data) and for multi-stage data preprocessing depending on the identified data class.
  • For example, the following methods can be used for data reduction:
    • - Objects that are too far away from your own vehicle are not taken into account or taken into account only if they signal a specific situation (for example ambulances). The relevant distance to the object is determined by its own speed, the direction of movement and, if appropriate, the type of message received. As a parameter, for example, the time to the probable reaching of the vehicle, object or the Situation to be used.
    • - Many local close objects with the same basic behavior are combined into one situation. For example, it can be a traffic jam (from many vehicles that stop) or slow traffic. Also, vehicle columns can be identified that have a certain column average speed on a busy road (rather than individual vehicles). Also, construction sites, etc. can be identified. If necessary, this situation analysis can be limited to the situations that are subsequently processed by the subsequent applications. For the situation analysis, the history of the information assigned to individual vehicles can be used.
    • - Only objects in their own "movement tube" or travel tube are taken into account. It is also possible to take into account only those objects which come close to or intersect the "movement tube" in a given time. The planned route can also be included in the determination of the movement tube so that information on this route is taken into account.
    • - Various object information is combined into a statement (information) (for example, stopped vehicle from the speed, the hazard lights, etc., or emergency braking from high pressure in the brake cylinder, brake light on and strong deceleration, etc.). Only this statement is then made available to the application.
    • - Parts of the transmitted information are discarded if these parts are currently not relevant and / or have not changed significantly.
    • - The resolution of the data is reduced if the higher resolution is not relevant (for example, for the position with more distant objects).
    • - In high-load situations, for example, only the critical messages are taken into account. Of these critical messages, only the messages relevant to the criteria described above will be passed.
    • Application-specific filters can be used, so that, for example, a downstream application (for example driver assistance system) for blue light vehicle warning only messages of blue light vehicles are forwarded, whereas in another application for congestion warning only the relevant relevant information will be forwarded.
  • The following procedures can be used to validate and correct the data (which is just an example and not an exhaustive list):
    • - The position of the neighboring communication subscriber can be set in relation to his own position. If there are distances that are relatively large, an error can be assumed. Especially if this distance does not match the number of communication hops and / or the communication range. In this case, a hop designates the single retransmission of a message as a broadcast and thus the forwarding to other objects (communication participants) outside the range of the original sender.
    • - Receiving errors or data errors can be corrected, for example, model-based. Thus, the orientation of a vehicle from the speed and its previous movement, etc. can be derived. In other words, the history is taken into account. State variables such as speed, accelerations, etc. can only change with certain (meaningful) rates of change.
    • - Driving dynamics variables including the position of different vehicles can be compared with each other and thus be mutually plausible.
    • - Action information (eg brake pressure, steering wheel angle, ...) can be compared with reaction quantities (eg speed, acceleration, position, ...). For example, this comparison is based on a specific model and these variables can be made mutually plausible.
  • Quality improvement can be achieved by, for example:
    • - The position of the objects is filtered over time, for example using statistical methods. This can reduce the typical error of GPS over time.
    • - Checked the position of the different objects to each other and also corrected over time.
    • - The received position is correlated with the reception field strength.
    • - Vehicle models or dynamic models are used to estimate the positions of the own vehicle and the objects in the environment and thus to continue, for example, to obtain a higher temporal resolution. This can be combined well with the filtering. In addition, so-called dead reckoning can also be used here.
    • - Delays (constant and variable) between the real position and the transmitted GPS position can be compensated. In this case, adaptive methods can be used or an identification (control conceptual meaning) of the delay can be performed. This compensation can be combined very well with the filtering and the updating.
  • The For example, the methods described are based solely on the Communication data and the information about the vehicle dynamics and GPS position of the own communication participant (own vehicle). Environment sensor data and Map data is not taken into account here. Such Consideration may be in an additional step done (for example, by a so-called sensor data fusion).
  • Become the data is cyclically transmitted at fixed intervals, so the order of the messages may be additional Relevance can be sorted. For example, messages can be passed to the applications first with high relevance.
  • In order to the data preprocessing as well as possible on the corresponding Applications, the parameters of data preprocessing, such as the time to reach the object through which Applications can be parameterized and designed. It is also possible that certain elements of data preprocessing depend on the applications actually used or activated be deactivated.
  • The described data preprocessing can be, for example before the local dynamic map (LDM) of the ETSI architecture in the Integrate facilities layer. For structural or positioning reasons it is also possible to do the data preprocessing after the Facilities Layer.
  • Also is it possible that data preprocessing is designed this way is that they are implemented on a separate controller is.
  • Of the Following ETSI nomenclature is the described data preprocessing can be used for all ITS stations, both for the Vehicle Station, as well as for the staff, Central or Roadside Station. For each of these different Stations, the data preprocessing is adjusted accordingly, since different application classes for each of these Stations are typical. This adjustment can be automatic (for example when installing the communication unit in the vehicle / infrastructure) or by external triggering (for example, by subsequent triggering) Uploading an appropriate software).
  • When Interface to the next processing layer can be a event-driven data transmission can be used. The means that only data is transmitted if previously defined events have taken place. This kind of Data transmission is useful if only applications that respond to specific events, for example Ambulance or stowed vehicles. Are however applications present, which analyze the environment completely and from this their conclusions If a sensor fusion takes place with environmental sensors, then It makes sense to send the data continuously.
  • In Dependence of applications and applications required reaction times is the maximum delay (Delay) to be determined by the data preprocessing. Especially at Filtering, etc. can be done by a slightly larger Delay a better quality of the then transmitted Data can be achieved. But this delay is critical to safety Information and applications are often intolerable. Optionally, the system may be so two or more representations of the data available to ask, with different delays, etc. These different representations can do this pure software (ie different API call or different Memory areas in shared memory areas) or really separate signal outputs from data preprocessing.
  • There every data entry from the outside a potential security risk (Security Risk) can also be used in data preprocessing a firewall or protection against viruses (to analogies from the Computer world). So can the Input data after a formal review, the compliance with basic rules, such as data volume, range of values, etc. are analyzed in certain patterns. This can happen to act as a so-called behavioral filter. This security layer can pay attention purely to substantive attacks. Cryptographic methods do not need to be done here. these can in the previous processing layer.
  • By the use of the described data preprocessing in C2X is less Computing power and memory for the actual applications necessary, since these only the relevant objects and situations have to look at.
  • 3 shows a possible architecture of an ITS station, for example, according to the current state of standardization at ETSI. It is a management unit 301 intended. Furthermore, the ITS station has applications 302 (for example on road safety, traffic efficiency, etc.), Facilities 303 , a network and transport unit 304 as well as an access unit 305 on. In addition, a security unit 306 intended. All units can communicate directly with the management unit 301 communicate. The units 302 - 305 can each with the management unit 301 and with the security unit 306 as well as with each other communi adorn.
  • The access unit 305 (Communication module 101 of the 2 ) can communicate wirelessly with external devices.
  • Become the received data during data preprocessing into several classes divided, these classes can be the most typical Applications for which this data is interesting are. The range limits are flexible and situation-dependent. The classification of the data into these classes is done according to different Criteria, whereby the classes are tested differently and can be preprocessed. That's the green class the infotainment data is very little pre-processed, whereas the safety data are heavily preprocessed (ie tested, validated, etc.).
  • By this different distribution of computing time to the different ones Areas can be ensured for a given total computing time, that safety-critical information the appropriate attention and thus have been allocated computation time.
  • The sorting into the classes can be done according to a simple scheme:
    • - Based on simple criteria, the first class (green) is separated from the rest.
    • - In the next step, additional criteria are used to separate the next class (yellow) from the remainder.
    • - So it goes on, until finally all objects are assigned to a class.
  • additionally In this way additional (meta) data can be generated, which were not transferred directly, but because of the relationship the data to each other or the history of the data are determined can. Furthermore, data are summarized, ie for Example of several vehicles for the information "traffic jam".
  • In order to ensure that safety-critical objects are also given enough attention in every case (eg, computing time), the scheme shown above can also be slightly modified:
    • - In the last processing step, the safety-critical objects (classes red and orange) are processed first, which were already safety critical in the previous processing step.
    • - Subsequently, with simple procedures (for example, distance to the own vehicle, time to collision, etc.) for potential further safety-critical objects (classes red and orange) searched.
    • - These objects are now completely preprocessed (ie validated, checked, additional data generated, etc.).
    • - Subsequently, the sorting takes place according to the above first scheme.
  • additionally can be provided, the areas green and yellow with hardware and / or software that is not designed to security standard is. The additional preprocessing steps for the classes orange and especially red become software and / or hardware performed the security standards (ASIL rating).
  • It lends itself to preprocessing according to safety standards to use known hardware and / or software So for example on processors and operating systems or software modules for ESP systems.
  • For example can be a computing unit of known systems, such as ESP (so for example the dual core CPU of Continental) used and thus the necessary efficiency of the Systems (especially in terms of safety / safety) can be achieved.
  • 4 shows the classification of C2X data into a green, yellow, orange, and red category. In the green category 406 are so-called entertainment data (infotainment data), which are transmitted for example by infrastructure facilities. In the yellow class 407 it is mobility assistance data, in the orange class 408 for driver assistance data and for the red class 409 to so-called safety data.
  • The safety data is the vehicle 401 , which moves towards an intersection, from the immediate vicinity 410 of the vehicle from a second vehicle also approaching the intersection 402 , an oncoming vehicle 403 , a following vehicle 404 and a traffic light system 405 transmitted. The data classified as red is preferably treated, so that the driver assistance system can be supplied with it, without wasting time. The mobility assistance data becomes the vehicle 401 out of the area 411 transmitted.
  • 5 shows an ITS system installed in a vehicle. The ITS system has an ITS antenna 501 on (DSRC, GPS, Cell), the communication unit 101 of the 2 equivalent. The data received from the antenna can be sent to the ITS sensor 502 be transmitted. The sensor 502 indicates a first preprocessing stage 503 with DSRC ITS Facilities Pre-Processing (ie a data pre-processing) processing unit 105 ) on. The pre-processed data in a first step are then a control unit 504 passed, which via a CAN interface and / or a so-called Flex Ray interface with the other vehicle components 505 is coupled. The control unit 504 corresponds to a higher safety level (safety, ASIL level) than the ITS sensor. In the control unit 504 In doing so, the safety-critical steps of preprocessing are carried out.
