The disadvantage of this method is that the purpose of path planning is to save time by avoiding congested road sections. The path planning of the test test is not to avoid congestion, but to pass all the characteristic road sections with as few repeated mileage as possible.

Embodiment 1

[0024] like figure 1 As shown, the actual road test scene selection and planning method of the intelligent driving mobile device of the present invention includes the following steps:

[0025] Step 1. Match the road parameters required by the test for the road parameter table and test function set required for different functional tests:

[0026] The road parameter table and test function set required for different functional tests can be stored in the database by manual decomposition and entry. The matching test requires road parameters to be matched by a technician according to common knowledge.

[0027] Search for roads that meet the screening conditions in the processed map library with the matching road parameters required for testing and add them to the set of primary selected road sections;

[0028] For example, the curve radius, slope gradient, intersection, traffic lights, speed limit signs, etc. can be used as the road parameter items to be searched for test requir...

Embodiment 2

[0041] like figure 1 As shown, the actual road test scene selection and planning method of the intelligent driving mobile device of the present invention includes the following steps:

[0042] Step 1: Use the map containing the road characteristic parameters as the filter condition, and search out the roads that meet the filter conditions in the processed map library and add them to the set of preliminary selected road sections;

[0043] Step 2: Plan a test path according to the selected test road section.

[0044] a), for the primary selection road section set, add two test road sections determined corresponding to a screening condition to the test road section set, and calculate the shortest path between the two test road sections correspondingly determined by the screening condition as the primary selection shortest path;

[0045] b), calculate the shortest path from the starting point to the shortest path of each primary selection, and select a path with the shortest leng...

Embodiment 3

[0059] like figure 1 As shown, the actual road test scene selection and planning method of the intelligent driving mobile device of the present invention includes the following steps:

[0060] Step 1. Match the road parameters required by the test for the road parameter table and test function set required for different functional tests:

[0061] The road parameter table and test function set required for different functional tests can be stored in the database by manual decomposition and entry. The matching test requires road parameters to be matched by a technician according to common knowledge.

[0062] The matching test requirements road parameters and the map containing the road feature parameters are used as filter conditions. The filter conditions can also be other input conditions. Search the processed map library to find the roads that meet the filter conditions and add them to the set of preliminary selected road sections; The road parameters required for testing, ...

Abstract

The invention relates to a real road test scene selection and planning method for an intelligent driving mobile device. The method is as follows: searching out a road that satisfies the screening conditions in a processed map library and adding it to a set of preliminary selected sections; for the set of preliminary selected sections, for For any screening condition, calculate the shortest path from the test road section determined by the screening condition to the existing test road section in the test road section set, and add it to the test road section set; perform deduplication processing on the test road sections in the test road section set to obtain a non-duplicate test road section set; Calculate the shortest test path between all test sections in the set of non-duplicated test sections, find all nodes in the shortest test path and calculate the length of the path between all nodes; for any two nodes, select the shortest length and the distance between the selected nodes The path forms an inter-node path of a closed loop; until the selection of the shortest path between all nodes is completed. The invention has the highest test efficiency and can ensure the test coverage.

Description

technical field [0001] The invention belongs to the technical field of road testing of intelligent driving mobile devices, and relates to a real road test scene selection and planning method and device for intelligent driving mobile devices. Background technique [0002] At present, the path planning function of map manufacturers can plan the path from point A to point B when point A and point B are known, but the existing path planning cannot meet the multiple scenarios in the test. [0003] At present, there is no road feature information on the map, and the road cannot be selected through the road feature; [0004] At present, the path planning function of multiple target points provided by map manufacturers cannot optimize the trajectory, and the order of the path points needs to be adjusted by the user. [0005] In the currently disclosed method for extracting local road information, the method searches for roads by ID, and receives a search position and a search range...
