Definitions
- the invention relates to a system for creating a digital map for driver assistance systems of a vehicle according to the preamble of claim 1 and to a method for creating a digital map with such a system according to the preamble of claim 13.
- Digital cards are known in the art.
- the increase in driver assistance systems in vehicles with higher degrees of automation is increasing the importance of digital maps, since these form a building block for the calculation and execution of driving maneuvers by the driver assistance systems.
- the interaction of the driver assistance systems with vehicle-to-X communication further improves the information base for decisions of the driver assistance systems.
- the disadvantage remains the fact that complex structures of the transport infrastructure, such. As road structures, road courses, gradients of tracks across multiple streets, from a system without digital maps are not clearly interpretable. It may also occur in such places that driving situations arise where the information content of vehicle-to-X messages is not sufficient to make a clear decision for a driving maneuver.
- the object is achieved according to a first aspect of the invention by means of a system of the aforementioned type, wherein the system emits a message with map data and / or a warning message upon detection of ambiguity.
- the invention is based on the recognition that detailed and up-to-date map data are required precisely when ambiguities of a driving situation occur which can not be unambiguously interpreted by a driver assistance system or where the ambiguity can not be resolved without further information. It is therefore advantageous in such situations to send messages with map data and to make available to other vehicles which can then use this map data to supplement, verify, compare and store their own map data for the future.
- the automatic exchange of messages between vehicles on the one hand has the advantage that high-quality map data are disseminated quickly. This benefits just those vehicles that are not well equipped on the software and hardware side.
- the invention offers the advantage that the transmission amount of map data is kept as low as possible or is used efficiently because the messages are sent with map data depending on ambiguous driving situations or the topological conditions.
- ambiguous driving situation primarily those situations to understand that are not clearly interpretable by means of a driver assistance system. Such situations may be due to structural conditions, eg. As the road structure or topology, or by temporary circumstances, eg. As site, caused. Such situations can arise around a critical position on a digital map, whereby the position here is not necessarily limited to a position point but a position range or a position Map section includes. The size of the area or of the section can vary and, for example, be determined by means of how large the area of influence of the respective driving situation is to be counted.
- unit comprises a functional unit.
- a device may include different hardware and software components necessary to perform a function. It may also be that certain components are assigned to several functional units.
- the digital card fulfills the purpose of enabling navigation and / or guidance of the vehicle, be it manual or automated.
- it includes at least the road topology of a geographical area including the associated traffic rules.
- the digital map may include multiple levels and levels of detail, in which further information such as: As driving and pedestrian lanes, road types, traffic density, traffic signs or signs, etc. are stored.
- the messages with map data contain the information in digital form.
- the recognition unit is designed such that it recognizes ambiguities on the basis of traffic structures, in particular road structures or topologies, course of lanes. In this way, criteria to which the system is to send a message with map data can be set particularly easily.
- the recognition unit recognizes ambiguities in: Overpasses,
- messages are received by the communication unit with map data and this abspei ⁇ chert in the card unit, in particular for forwarding to other vehicles.
- the recognition unit is designed to detect ambiguities based on received messages with card data.
- the recognition unit can perform an analysis of the driving situation for ambiguity based on the map data in the message.
- receiving such a message itself may be used as a trigger to send out a message of its own, especially if the own map data is considered complete or correct.
- the system is designed to transmit the message with a time interval and / or distance before reaching the position. In this way, a timely Provision of map data ensured.
- the distances are determined on the basis of the distance between the own position to the respective critical position and / or on the basis of the distance of another vehicle from this position.
- the system is designed to check before sending a message whether a message with map data has already been sent to a position from another communication user. This prevents similar messages from being sent multiple times, and data without high added value does not increase data bandwidth and data load.
- the system is designed such that, upon receipt of a message with card data, it is checked whether the sender of the message is within a predefined plausibility radius around the position.
- the message with the map data is a MAP message.
- the MAP message is a message defined according to the SAE J2735 standard (last updated Sept 2015).
- MAP messages are not excluded which are defined according to other standards which, for example, have not yet been finally decided and published at the time of the application but are being processed.
- Such MAP messages are intended to be encompassed by the invention.
- MAP messages are usually only from fixed infrastructure so-called road side units, such. Traffic lights, sent. Sending MAP messages by vehicles is therefore a novelty. It has the advantage that the predefined structures of the MAP message simplify analysis and processing of the map data contained therein. It is therefore suitable for better resolution of the driving situation to a position in the digital map.
- the recognition unit is designed to recognize ambiguities of driving situations which are erroneously caused due to information in a received vehicle-to-X message. In this way, unnecessary transmission of messages with map data can be prevented.
- the system is designed such that upon detection of an ambiguous driving situation, for. B. caused incorrectly, only a warning message is sent. In such a situation it is sufficient to send out a warning message about the ambiguous situation.
- the warning message can be defined as proprietary. It is a message whose memory requirements are much smaller than those of a message with map data.
- the map unit is designed to integrate the map data in the messages in the digital map of the vehicle such that messages with high utility value integrated into the digital map of the own vehicle and optionally stored puzzle.
- Step Send includes a message with map data and / or a warning message upon detection of an ambiguity.
- the method according to the invention is advantageously further developed by checking before sending a message whether a message with map data has already been sent to a position by another communication user.
- the method according to the invention is advantageously further developed by checking, on receipt of a message with card data, whether the sender of the message is within a predefined plausibility radius around the position.
- FIG. 1 shows an ambiguous interpretable driving situation with multiple vehicles.
- Figure 1 shows two streets Sl, S2, which cross at a first position PI and overlap in sections at a second position P2 and run parallel.
- the first street Sl runs at the two mentioned positions PI, P2 as transfer above the second street S2.
- On the streets Sl, S2 are each two vehicles Fl, F2, which are equipped with a system 1 according to the invention.
- Fl, F2 On the streets Sl, S2 are each two vehicles Fl, F2, which are equipped with a system 1 according to the invention.
- F3, F4 which are equipped with a system 1 according to the invention, but whose digital maps are not complete and / or obsolete.
- the direction of travel of the vehicles F1-F4 is shown with a corresponding arrow. It may be left open which type of driver assistance systems are installed in these vehicles.
- the system comprises a communication unit for exchanging messages between vehicles, a position detection unit for detecting the position of the own vehicle, a map unit for storing and processing a digital map, and a recognition unit for detecting ambiguities of a driving situation to a position in the digital map. Detects the recognition unit a Mehrdeu ⁇ ACTION a driving situation, such as in the positions PI and P2 is the case, the system 1 sends a message with map data, which are received around the other vehicles F3 and F4. In this way it can be prevented that a collision warning system in the vehicles F3, F4 triggers a warning.
- the vehicle F4 At the position PI, the vehicle F4 would not recognize, due to the simple design of the digital map, whether this is an overpass or an intersection. Thus, there is an ambiguity in his own driving situation for the vehicle F2 where it can not clearly decide between an intersection and a transfer.
- the collision warning system of the vehicle F4 would accordingly warn of a collision with the vehicle F1. If the vehicle Fl now transmits a message with the complete map data in good time before reaching the position PI and the vehicle F4 receives and evaluates it, it can resolve the ambiguity based on the received map data. At the very least, if the message is stored in its own digital map, it can be ensured that the problem mentioned above does not occur the next time the position is traversed.
- the vehicle F2 therefore sends a message with map data before it ⁇ position P2 is sufficient to resolve the ambiguity.
- This distance can be measured in time or in meters, for example. 100m to 300m.
- the messages with the map data are ideally sent as MAP messages whose message structure is defined, inter alia, by the SAE J2735 standard.
- the received messages will then also be stored in the digital map of the received vehicle for the future. Possibly. can be sent again from ⁇ during a new or subsequent passage of the positions at which a message was received the same message, if it is not already done by another vehicle.
- the detection of position where ambiguous driving situations can occur can be done in different ways.
- a predefined list of road topologies can be used. For example, when approaching overpasses, bridges, tunnels, bends, especially tight bends, several adjacent divergent or merging road sections, driveways, especially on expressways, and / or multi-lane intersections, the recognition unit may emit a message with map data. This information can be taken from one's own digital map. On the other hand, this information can be extracted from the received messages with map data, especially if these are MAP messages. It should be noted that the list is only an example and not exhaustive. Furthermore, it is also possible, for example, to remember the Po ⁇ sitions, at which one has received a message with map data.
- the information can be coded, for example, in a special message that is initially proprietary to the respective manufacturer.
- the detection of the wrong interpretation can be done on the basis of the deviation of a digital map to a prediction without a map. If this deviation is too large, one special is sent message, which contains the location of the place where would be misinterpreted, and the reason the wrong Interpretation ⁇ tation.
- Reasons can be the above ambiguous situations.
- the corresponding message is clear smaller than a MAP message and not interpretable by all vehicles, which may be desired.
