Problems solved by technology
[0004] However, due to the large number of entities provided in the ontology model, testers usually choose entities based on previous experience when selecting entities. Different testers may choose different entities, and there may be missing entities or multiple entities. As a result, the simulated test scenarios constructed are inaccurate and affect the simulation test results of the vehicle

Embodiment Construction
[0042] The technical solution in this application will be described below with reference to the accompanying drawings. For ease of understanding, the terms involved in the embodiments of the present application are introduced first.
[0043] 1. Ontology model. Ontology model can be understood as a model that abstracts reality according to the concepts in real life, the relationship between concepts, the characteristics (ie attributes) of concepts, and the instances of concepts.
[0044] 2. Ontology model. The ontology model can be understood as describing the traffic elements (i.e. entities) in the road traffic scene through the ontology model, the classes (i.e. concepts) to which the traffic elements belong, the relationship between the traffic elements, and the characteristics (attributes) of the traffic elements. Wait.
[0045] 3. Entity. The entity in the ontology model is used to describe the static traffic elements and dynamic traffic elements in the real road traffic s...

The invention provides a vehicle simulation test scene construction method and device, and can provide simulation test scenes for intelligent automobiles, automatic driving automobiles, and connected automobiles. According to the method, after a first entity is selected from an ontology model based on a to-be-tested task, one or more second entities associated with the first entity are automatically selected from the ontology model based on a preset entity association relationship in the ontology model, and a simulation test scene is constructed based on the selected first entity and the one or more second entities, so that the situation of missing or more entities in the process of constructing the simulation test scene based on manually selecting entities by testers in the prior art is avoided, and the accuracy of constructing simulation test scenes is improved.
Description
technical field [0001] The present application relates to the field of automatic driving, and more specifically, relates to a method and device for constructing a simulation test scene of a vehicle. Background technique [0002] In the case of road tests, the proportion of driver errors will increase with the accumulation of test distance, and a variety of extreme dangerous scenarios are not suitable for real people to operate. Therefore, compared with a series of limitations such as high test cost, long test period, and many test accidents of road test, simulation test is better than road test to a certain extent. In the case of simulation testing, the construction cost of the simulation scene library is low, and it is not restricted by conditions such as weather and region, effectively avoiding personal and property injuries. And put more attention on human-vehicle-environment interaction. In addition, the simulation test combines the real hardware system with the simula...
