Definitions
- the invention relates to a method for estimating a coverage of the area of traffic scenarios and a computer program.
- An autonomous vehicle is one that is able to sense its surroundings and navigate with little or no user input.
- An autonomous vehicle detects its surroundings using sensor devices such as radar, lidar, image sensors and the like.
- the drivers are supported by at least one modern assistance system, such as cruise control with distance control or a lane departure warning system.
- at least one modern assistance system such as cruise control with distance control or a lane departure warning system.
- Level 2 semi-automated driving, combines two or more assistance systems, such as the traffic jam assistant, which keep a distance and keep lane in stop-and-go traffic.
- the vehicle drives completely independently in some traffic situations, so it can brake, steer, accelerate and change lanes itself. This also works over longer distances or periods of time. However, the route is precisely specified.
- highly automated driving which is sometimes also referred to as fully automated driving
- drivers can hand over driving to the control system for a longer period of time.
- highly automated driving can only be limited to certain geographical areas and / or only to a small speed range and / or only work under certain weather conditions.
- level 5 autonomous driving, the vehicle takes over all driving functions. In contrast to level 3 and level 4, there is neither one in autonomous driving In order to be able to drive, a driver's license is required - steering wheel and pedals are therefore also dispensable.
- level 4 and level 5 Compared to level 2, the partially automated driving, the test effort for level 4 and level 5 is multiplied and the validation task becomes much more complex. Levels 4 and 5 in particular require an enormous amount of development effort, as an unprecedented amount of traffic and test scenarios must be taken into account in order to bring the systems to market maturity.
- the object of the invention is to specify means with which it is possible to estimate how many of the traffic scenarios collected have already been recorded in relation to the totality of all traffic scenarios.
- the object is achieved by a computer-implemented method for estimating the coverage of the area by traffic scenarios comprising the following steps:
- the area of traffic scenarios is understood to mean the entirety of all traffic scenarios that occur in traffic.
- a traffic scenario is understood as a restricted section of the entire traffic situation.
- Unknown traffic scenarios are traffic scenarios that have not yet been recorded.
- This classification and / or clustering allows, on the basis of a statistical method applied to it, the estimation of the scenario area coverage and the estimation of the occurrence of future, unknown traffic scenarios.
- key figures are defined in advance.
- the various traffic scenarios are preferably generated by means of simulation.
- a virtual simulation tool can generate a large number of traffic scenarios, road and environmental conditions from, for example, virtual sensors. Then, for example, simulated disruptions in these traffic scenarios can be used to generate new traffic scenarios. These traffic scenarios are varied by a disruptive factor (e.g. weather change) in order to create new and additional traffic scenarios.
- a disruptive factor e.g. weather change
- the various traffic scenarios are preferably generated from sensor data that are recorded by a stationary and / or mobile traffic recording system.
- a mobile traffic detection system can, for example, be the detection system of a test vehicle. Several test vehicles can also be used for this purpose. Alternatively, cell phone cameras etc. can be used. For example, a traffic camera and / or traffic monitoring device can be used as the stationary traffic detection system. These represent a comprehensive and at the same time inexpensive data source.
- the various traffic scenarios are alternatively or additionally preferably generated from purely recording data sources, such as drone data, for example.
- Other sources can be database systems in which vehicles that are actually moving, for example, provide routes traveled for a fee as traffic scenarios.
- a clustering method is used as the classifier. This can speed up the process.
- a self-learning system from artificial intelligence is preferably used as the classifier.
- the classifier can in particular be implemented as a neural network, in particular as a deep neural network. These can process large amounts of data.
- the classification is preferably carried out by means of a trained classifier, the classifier being trained on the basis of distinguishing features.
- Possible distinguishing features include, for example, physical quantities, such as position, orientation, speed, acceleration and time, which describe the movement of traffic objects relative to one another.
- An extrapolation method is preferably used as the statistical method.
- An extrapolation method makes a statement about the area that has not been recorded, taking into account the area that has already been recorded, in this case the traffic scenarios. This method is therefore particularly suitable for predicting the future occurrence of unknown traffic scenarios on the basis of the classification / clustering.
- kernel density estimator can also be used as a statistical method. Kernel density estimators are methods that enable a continuous estimation of the unknown distribution. This kernel density estimator is known to approximate not only a uniform distribution, but also arbitrary distributions and is therefore particularly suitable for predicting the future occurrence of unknown traffic scenarios.
- a Good-Toulmin estimator or an Efron-Thisted estimator or variants thereof can be used as statistical method.
- These estimators are represented in ecology and deal with the estimation of the number of species that are represented in an ecosystem and which have not previously been observed in samples taken. In particular, they relate to how many new species would be discovered if more samples were taken from an ecosystem. Thus these estimators can be used by skillful transfer to predict the future occurrence of unknown traffic scenarios forecast.
- the Good-Toulmin estimator or the Efron-Thisted estimator or variants thereof are particularly scalable and therefore suitable for large amounts of data. Furthermore, these can be calculated quickly.
- the Good-Toulmin-Estimator or the Efron-Thisted-Estimator or variants thereof thus represent sensible and feasible estimators which deliver very good results under the framework conditions mentioned here.
- the key figures include a number of the unknown traffic scenarios and / or a statistical distribution of the unknown traffic scenarios. These key figures are particularly suitable for estimating the scenario space coverage.
- the specified key figures provide information about the extent to which the previously recorded scenario area covers the area of all traffic scenarios. For example, the number of unknown traffic scenarios estimated by the classification / clustering and the statistical distribution of these unknown traffic scenarios come into consideration as key figures.
- the key figures include, for example, a criticality of the unknown traffic scenarios.
- the criticality describes the danger of a traffic situation (critical traffic situation) in which an intervention of a driver assistance system or a driver is necessary.
- the key figures can be included in the assessment in a weighted manner. For example, one high criticality can outweigh several less critical, unknown traffic scenarios.
- New critical traffic scenarios are preferably simulated on the basis of the criticality of the unknown traffic scenarios.
- new critical traffic scenarios are preferably simulated on the basis of the recognized, unknown traffic scenarios. This can be done, for example, by varying the critical or unknown traffic scenarios found. One or more parameters of the identified critical traffic scenarios can be changed. As a result, the already existing number of traffic scenarios can be specifically condensed with new simulated critical traffic scenarios. Using the recognized, unknown traffic scenarios, the traffic scenarios that are already available can also be compressed in a targeted manner.
- the traffic scenarios preferably relate to selected routes or a selected area. The method can thus be terminated more quickly. These traffic scenarios can be used, for example, to validate level 4 or level 5 driving functions.
- a device for data processing comprising a processor which is configured to carry out the method as described above.
- FIG. 1 shows a first embodiment of a method according to the invention.
- FIG 2 a second embodiment of the method according to the invention
- FIG. 3 shows a third embodiment of the method according to the invention.
- traffic scenarios are provided in a first step S1. These can be generated, for example, by recording real traffic scenarios using measuring systems in test vehicles or by simulating them. During the simulation, for example, real traffic scenarios can be modified in order to generate new traffic scenarios.
- the traffic scenarios relate to all routes, i.e. the scenario space corresponds to the entirety of all traffic scenarios in traffic. Alternatively or additionally, cell phone cameras, drones, etc. can be used to generate real traffic scenarios. Also one Generation of real traffic scenarios by stationary and / or traffic detection systems such as a traffic camera and / or traffic monitoring device is alternatively or additionally possible. These represent a comprehensive and at the same time inexpensive data source.
- Other sources can be database systems in which vehicles that are actually moving, for example, provide routes traveled for a fee as traffic scenarios.
- these traffic scenarios are clustered and divided into known or unknown traffic scenarios.
- the clustering can take place by means of a clustering process.
- the provided traffic scenarios can be divided into known or unknown traffic scenarios.
- a statistical method is applied to the clustered traffic scenarios in order to estimate predetermined key figures which describe the approximate coverage of the scenario space.
- the specified key figures provide information about the extent to which the previously recorded scenario area covers the area of all traffic scenarios.
- the number of unknown traffic scenarios estimated by the clustering and the statistical distribution of the unknown traffic scenarios determined in this way and the criticality of the unknown traffic scenarios determined in this way come into consideration as key figures.
- the criticality describes the dangerousness of a traffic situation (critical traffic situation) in which an intervention of a driver assistance system or a driver is necessary.
- An example of a critical traffic situation is when there is a risk of collision between the vehicle and another vehicle / obstacle or when a minimum distance between the vehicle and another vehicle / obstacle is not reached. Other critical traffic situations are also conceivable.
- the key figures are estimated and, based on the estimate, the method is terminated or the method is continued. If, for example, the scenario space coverage is still insufficient, further traffic scenarios must be generated. However, if, for example, unknown traffic scenarios "sufficiently" rarely occur, this means a sufficiently large coverage of the scenario space and the method can be aborted. A sufficiently large coverage can be specified individually, for example by the manufacturer.
- a fifth step S5 the method is aborted on the basis of the estimate. In this case, sufficient coverage of the scenario space has been achieved and the procedure can be terminated.
- a sixth step S6 the scenario area coverage is still insufficient and new traffic scenarios must be generated on the basis of the critical and / or unknown traffic scenarios found.
- a critical previously unknown traffic scene can be a maneuver with several vehicles in the roundabout, with the test vehicle generating the sensor data managing the roundabout at a speed of 20 km / h.
- simulation can be used to generate traffic scenarios in which the test vehicle negotiates the roundabout at a speed of 50 km / h.
- the parameter environmental conditions such as rain, snow or fog, can be changed.
- the procedure is continued with newly generated traffic scenarios.
- the method can be used to estimate a statistical forecast of the future occurrence of "unknown" traffic scenarios. If the scenario space is sufficiently covered, a virtual test of the traffic scenarios present in the scenario space can be carried out using a virtual test vehicle.
- FIG. 2 shows a second embodiment of the method according to the invention.
- a first step A1 several traffic scenarios are again made available.
- the traffic scenarios relate to all routes, i.e. the scenario space corresponds to the entirety of all traffic scenarios in traffic.
- these traffic scenarios are classified with a trained classifier and divided into known or unknown traffic scenarios.
- the classifier is a classifier trained on distinguishing features. Possible distinguishing features include physical quantities (position, orientation, speed, acceleration and time) that describe the movement of traffic objects in relation to one another.
- a statistical method is applied to the classified traffic scenarios in order to estimate the specified key figures with regard to the scenario area coverage.
- the specified key figures provide information about the extent to which the previously recorded scenario area covers the area of all traffic scenarios.
- the extrapolation method can be used as a statistical method.
- a kernel density estimator can be used. It is also possible to use a Good-Toulmin estimator or an Efron -Thisted estimator or variants thereof as the statistical method.
- a fourth step A4 the key figures are again estimated and the method is terminated or the method is continued on the basis of the estimation.
- a sufficient scenario coverage is recognized on the basis of the estimate and the method is then terminated.
- the scenario area coverage is still insufficient and new traffic scenarios must be generated on the basis of the critical and / or unknown traffic scenarios found. The procedure is continued with newly generated traffic scenarios.
- FIG. 3 shows a third embodiment of the invention.
- a first step B1 several traffic scenarios are again made available.
- the traffic scenarios preferably relate to selected routes or to a specific pre-selected area.
- these traffic scenarios are first clustered, for example using a density-based clustering method.
- the clusters are then classified with a trained classifier and divided into known or unknown traffic scenarios.
- the classifier is a classifier trained on distinguishing features. Possible distinguishing features include physical quantities (position, orientation, speed, acceleration and time) that describe the movement of traffic objects in relation to one another.
- a statistical method for example an extrapolation method, is applied to the classified traffic scenarios in order to estimate predetermined key figures which describe the coverage of the scenario space.
- a fourth step B4 the key figures are again evaluated.
- a fifth step B5 an adequate scenario area coverage is recognized on the basis of the estimate and the method is then terminated.
- new traffic scenarios are generated on the basis of the critical and / or unknown traffic scenarios that have been found. This can be done, for example, by varying the critical and / or unknown traffic scenarios found. One or more parameters of the identified critical traffic scenarios can be changed. The procedure is continued with newly generated traffic scenarios.
