Definitions
- the invention relates to a method for evaluating route sections according to the preamble of claim 1.
- the invention also relates to a method for operating a vehicle.
- a method for fully automated ferry operation of a vehicle is known from WO 2018/197255 A1, in which the vehicle is localized on the basis of landmarks that are stored in a digital map.
- Fully automated ferry operations are only permitted on sections of the route that have been approved for such ferry operations. The prerequisite for this approval is that a localization accuracy with which the vehicle can be localized on a route section lying ahead meets specified requirements that are dependent on the respective route.
- the localization accuracy for the route section ahead is predicted on the basis of a spatial density of the landmarks stored in the digital map.
- DE 102014014 120 A1 discloses a method for autonomously operating a vehicle on a route ahead.
- the autonomous operation of the vehicle is only permitted if it is fulfilled for a given length of the route ahead that a position of the vehicle in the vehicle is determined with a position accuracy that is better than a given limit value, and digital map data on the course of the road are available with a position accuracy that is better than a predetermined limit.
- the as yet unpublished DE 102019 007861.6 describes a method for clearing a route for an automated ferry operation of a vehicle, with a route ahead of the vehicle for an automated ferry operation of the The vehicle is released when it is determined by means of a digital map, which is used for landmark-based localization of the vehicle during the automated ferry operation, that there are landmarks along the route which meet requirements with regard to their suitability for longitudinal and lateral localization of the vehicle, which are specified as a function of a course of the route. Furthermore, a maximum driving speed of the vehicle for the automated ferry operation is specified on the basis of a localization accuracy of the vehicle and depending on the route section.
- the invention is based on the object of specifying a method, which is improved over the prior art, for evaluating route sections of a digital map with regard to their suitability for automated ferry operation of a vehicle and a method for operating a vehicle.
- the object is achieved according to the invention by a method for evaluating route sections, which has the features specified in claim 1, and by a method for operating a vehicle, which has the features specified in claim 9.
- a spatial density of landmarks is determined according to the invention for each route section of the digital map. Furthermore, for each route section, an expected recognizability of the landmarks is determined by a vehicle sensor system under specified environmental conditions, based on the determined density and recognizability of the landmarks, a classification is carried out to determine whether a vehicle on the route section is required for a specified operating mode and / or for a specified driving maneuver Minimum accuracy can be localized.
- a classification result is stored as a data record in a route attribute assigned to the route section, the route attribute indicating for which of the specified operating modes and / or driving maneuvers under which of the specified environmental conditions requirements for the minimum accuracy of the landmark-based vehicle localization are met.
- the accuracy of a map-based localization of a vehicle is at least partially dependent on a number of available landmarks, that is, landmarks, and features for data assignment in a local, detectable environment.
- an automatically driving vehicle must automatically cover a longer distance of, for example, up to two minutes in order to reach a safe location, for example a hard shoulder several hundred meters away can be achieved.
- the integrity for example according to ISO 26262
- the integrity can be low. That is, if only one type of features, for example only so-called poles, or only one type of sensor modality, for example only one lidar, which typically meets a so-called Automotive Safety Integrity Level B, ASIL B for short, but not ASIL D, an automated vehicle must also react to such a reduction in integrity and reduce its performance.
- route sections with a low density of landmarks which could lead to a high level of uncertainty and / or a low integrity of the pose of an automatically driving vehicle, can be used for future routes of the vehicle based on an evaluation of map data, for example a priori maps and / or dynamic map data, and an environmental perception can be predicted.
- map data for example a priori maps and / or dynamic map data
- an environmental perception can be predicted.
- route sections with a low density of landmarks are on a route of a vehicle
- a behavior and / or a trajectory of the automatically driving vehicle can be adapted in such a way that a sufficiently precise, safe and redundant pose of the vehicle for can provide safe automated operation based on a small number of landmarks.
- the automated vehicle can proactively and in advance of a decrease in density and / or recognizability of the landmarks and a critical gradual or sudden loss of localization avoid the can lead to dangerous events and / or difficult situations.
- the expected recognizability is determined for each lane present on the route section and / or for different transverse positions of the vehicle within a lane. This enables an exact prediction of the recognizability of the landmarks for each lane and / or transverse offset and thus, when used in an operation of an automated driving vehicle, a determination of a route that is optimized with regard to safety.
- the classification result and the associated route attribute are used to specify in which lane and / or in which lateral position of the vehicle the minimum accuracy of the vehicle localization required for the respective operating mode and / or for the respective driving maneuver can be maintained. When used in an operation of an automatically driving vehicle, this also enables a route that has been optimized with regard to safety to be determined.
- the classification result and the associated route attribute are used to indicate which lane and / or which lateral deposit of the vehicle is or is most suitable for the respective operating mode and / or the respective driving maneuver. This makes it possible for an operating mode to be selected in advance in which the vehicle is most likely to safely reach its destination.
- the classification is carried out on a central processing unit external to the vehicle, for example a so-called backend server.
- a central processing unit external to the vehicle, for example a so-called backend server.
- this makes it possible that no additional computing power is required in the vehicle itself to carry out the classification.
- the classification for a large number of vehicles can be carried out centrally and thus effectively and inexpensively.
- information about the recognizability of the landmarks and / or current environmental conditions while vehicles are passing the landmarks are recorded.
- the information recorded in this way can be processed decentrally in the vehicles themselves to classify the route sections or can be transmitted to a suitable central processing unit external to the vehicle, which carries out the classification. Due to the large number of vehicles, a very reliable acquisition of the information about the recognizability of the landmarks is possible, as a result of which the reliability of the classification can be significantly increased.
- a fully automated ferry operation of a vehicle, a highly automated ferry operation of a vehicle and / or an operation of a vehicle in a certain speed range are specified as operating modes and / or lane keeping maneuvers, lane change maneuvers, overtaking maneuvers and / or turning maneuvers are specified as driving maneuvers.
- This specification of the operating modes and / or driving maneuvers allows an individually adapted determination of a safe route for a vehicle, taking into account the route attributes.
- the method can increase the safety and reliability of the operation of the vehicle, since route sections with a low density of landmarks, which could lead to a high level of uncertainty and / or a low integrity of the pose of an automatically driving vehicle, are based on future routes of the vehicle an evaluation of map data, for example a priori maps and / or dynamic map data, and a perception of the surroundings can be predicted.
- map data for example a priori maps and / or dynamic map data
- a perception of the surroundings can be predicted.
- a behavior and / or a trajectory of the automatically driving vehicle can be adapted in a simple manner to the known route attributes so that, for example, a sufficiently precise, safe and redundant pose of the vehicle for a safe automated operation based on a small number of landmarks can be provided.
- the route attributes are retrieved from the vehicle by a central processing unit, for example a so-called backend server.
- a central processing unit for example a so-called backend server.
- this makes it possible that no additional computing power is required in the vehicle itself to carry out the classification.
- the classification for a large number of vehicles can be carried out centrally and thus effectively and inexpensively.
- particularly precise and reliable route attributes can be generated and made available for each vehicle by means of the central processing unit.
- FIG. 1 schematically shows a block diagram of a device for operating a vehicle according to the prior art
- FIG. 2 schematically shows a block diagram of a device for operating a vehicle
- FIG. 3 schematically shows a top view of a route of a vehicle with several route sections.
- FIG. 1 shows a block diagram of a device 1 for operating an automated, in particular highly automated or autonomously driving vehicle according to the prior art.
- the device 1 comprises a digital map 2, a vehicle sensor system 3, a localization unit 4, a modeling unit 5 for generating a model of a vehicle environment, and a behavior planning unit 6.
- the localization unit 4 the vehicle is localized in its vehicle environment using environmental data acquired by means of the vehicle sensor system 3, for example acquired landmarks, and / or map data from the digital map 2, for example landmarks stored in the map.
- a vehicle pose is transmitted to the modeling unit 5, which generates a model of the vehicle environment.
- the behavior planning unit 6 plans future behavior of the vehicle during the automated ferry operation.
- FIG. 2 shows a block diagram of a possible exemplary embodiment of a device 7 for operating an automated, in particular highly automated or autonomously driving vehicle 8 shown in FIG. 3.
- a basic function of device 7 corresponds to a function of device 1 shown in FIG.
- the accuracy of a map-based localization of a vehicle 8 is at least partially dependent on a number of available landmarks and features for data assignment in a local, detectable vehicle environment. If, however, there are only a small number of landmarks, the accuracy of a primary localization function based on these landmarks and carried out by means of the localization unit 4 decreases to a point at which the determined vehicle pose is no longer accurate enough and evasive methods, such as one based on odometry data dead reckoning, must be used to temporarily determine vehicle pose. However, these evasive methods are generally less precise than localization based on map feature corn and quickly lead to high uncertainties when determining the vehicle pose, especially at medium to high speeds.
- a scarcity of landmarks can, for example, have static causes and results, for example, from properties of the environment, such as a country road without buildings, without masts and / or without lane markings, which can be used (a priori) as perceptible landmarks.
- the scarcity of landmarks can, however, also have dynamic causes and in this case results, for example, from conditions that limit the performance of the vehicle sensor system 3 that detect the landmarks. This can include, for example, unfavorable environmental conditions, such as a Sun glare or snow, or traffic scenarios, such as vehicles, trucks or buses, which cover a field of view of the vehicle sensor system 3, be.
- route sections FS1 to FS3 shown in more detail in FIG. 3, to be assessed in terms of their suitability for automated ferry operation of vehicle 8 in digital map 2 in which landmarks are stored for landmark-based vehicle localization.
- a spatial density of landmarks and an expected recognizability of the landmarks are determined by the vehicle sensor system 3 under given ambient conditions, in particular given light conditions, times of day, precipitation and / or properties of surrounding objects.
- the expected recognizability is determined in particular for each lane present on the route section FS1 to FS3 and / or for different transverse positions of the vehicle 8 within a lane.
- the spatial density of the landmarks is determined, for example, by an offline analysis of the digital map. Alternatively or additionally, the spatial density of the landmarks is determined on the basis of sensor data from vehicle 8, from surveying vehicles, other automated vehicles 8, by so-called crowd sourcing or so-called swarm sources, with the sensor data being evaluated in terms of performance and Redundancy of a recognition of landmarks along a specific route or lane can be evaluated.
- a performance can depend on a direction of travel and / or a lane being traveled on.
- information about the recognizability of the landmarks and / or current environmental conditions while the landmarks are being passed is recorded by a plurality of vehicles 8, for example vehicles 8 of a vehicle fleet, and transmitted to a central processing unit 9 external to the vehicle, shown in more detail in FIG.
- the central processing unit 9 uses the determined density and recognizability of the landmarks to classify whether a vehicle 8 can be localized on a route section FS1 to FS3 with a minimum accuracy required for a given operating mode and / or for a given driving maneuver.
- the operating modes are, for example, a fully automated ferry operation of a vehicle 8, a highly automated ferry operation of a vehicle 8 and / or an operation of a vehicle 8 in a specific Speed range can be specified.
- lane keeping maneuvers, lane change maneuvers, overtaking maneuvers and / or turning maneuvers are specified as driving maneuvers.
- a classification result is stored as a data record in a route attribute assigned to the route section FS1 to FS3, the route attribute indicating for which of the specified operating modes and / or driving maneuvers under which of the specified environmental conditions requirements for the minimum accuracy of the landmark-based vehicle localization are met.
- the classification result and the associated route attribute it is indicated, for example, in which lane and / or with which lateral deposit of the vehicle 8 the minimum accuracy of the vehicle localization required for the respective operating mode and / or for the respective driving maneuver can be maintained.
- the classification result and the associated route attribute it can also be specified which lane and / or which lateral deposit of vehicle 8 is or is most suitable for the respective operating mode and / or the respective driving maneuver.
- the classification can, for example, distinguish between the following route attributes:
- Landmarks only available with a certain sensor modality.
- route attributes can be extended in such a way that they also include and classify a probability of a low density of landmarks due to restrictions of the vehicle sensor system 3 as a function of certain environmental conditions, such as, for example, light conditions such as daylight, night, twilight;
- Times of day such as driving towards a sunset, which can cause glare; Precipitation such as rain, snowfall and fog; and / or properties of surrounding objects, for example their reflectivity.
- the route attributes are expanded to include a probability of insufficient landmarks due to restrictions of the vehicle sensor system 3 depending on traffic situations, for example due to occlusions due to tall vehicles, and / or special events, for example smoke due to forest fires. These route attributes are evaluated in the vehicle, for example, taking into account a current traffic situation and the events which are provided by the central processing unit 9 or are detected in advance by the vehicle sensor system 3.
- the modeling unit 5 can thus generate an adapted model of the vehicle environment based on the knowledge of the route attributes and possibly further information from the digital map 2, the vehicle sensor system 3, the central processing unit 9 and / or by means of machine learning 10 and, if necessary, sends corresponding information for adaptation and Limitation of the operation of the vehicle 8 to the behavior planning unit 6.
- the connections shown as interrupted represent interfaces which are used by the modeling unit 5 to predict the model.
- FIG. 3 shows a top view of a route FS of a vehicle 8 with several route sections FS1 to FS3.
- the vehicle 8 moves in a route section FS1 in a normal autonomous ferry operation in the direction of the route sections FS2, FS3. Due to the knowledge of the route attributes determined according to the description, it is already known before the route sections FS2, FS3 are reached that in route section FS3 There are restrictions for the automated ferry operation of the vehicle 8. For this purpose, the route attributes are called up by the vehicle 8, for example from the central processing unit 9.
- the vehicle 8 can already restrict certain operating modes and / or driving maneuvers when it reaches the second route section FS2 and / or determine a route, lane, transverse deviation and / or driving speed to be maintained during the automated ferry operation so that when entering the third route section FS3 safe operation of the vehicle 8 is possible despite the low density of landmarks.
- This can be carried out online or offline and checks the route attributes of the route sections FS1 to FS3 lying ahead and determines areas with a high probability of a low density of landmarks. If such an area, such as the route section FS3, is determined, the adaptation measures are triggered before this route section FS3 is reached.
- the adaptation measures include, for example: an adaptation or reduction of a vehicle speed; a preference for a position within a lane (left, center, right); a preference for a particular lane on a multi-lane carriageway; a restriction of a vehicle behavior, for example an inhibition of more complex maneuvers, such as for example lane changes; a choice of another route; and or
- adaptation measures can be triggered either directly by sending dedicated commands to the behavior planning unit 6 and / or indirectly by artificially changing quality or integrity information data, for example in an interface to the behavior planning unit 6, in order to trigger a tactical safety reaction.
