Description
Technical field
The present invention relates to automatic Pilot technical field more particularly to a kind of scene management methods of DAS (Driver Assistant System).
Background technique
With the fast development of intelligent driving and ADAS (Advanced Driver Assistance System, it is advanced auxiliary
Help control loop) technology it is increasingly mature, ADAS industry receives more and more in functional study and product development process
Concern.During traditional ADAS functional development, due to a lack of effective verifying means, field test is tested in advance generally as function
The main means received and judged, and road test is then generally as the main foundation of functional safety, reliability evaluation.And with
The development of measuring technology, software ring test SIL, hardware-in―the-loop test HIL, vehicle the means of testing such as ring test VIL because at
This is low, the period is short, can quickly carry out limiting condition test, the advantages that robustness is good, obtain lot of domestic and foreign automobile vendor and
The favor of components exploitation enterprise.
Further to promote testing efficiency, meets diversification test request, as the important component of test process, survey
The core for being constructed so that testing research of examination hall scape.
The building of existing test scene, generally by vehicle (containing kinetic model), sensor model, traffic flow, road information,
Control strategy deposits in same file, during the test, for different function and scene, runs one by one.Although with top
Case greatly advances ADAS scenario building and use, also takes on increasingly important role in project development, but
It is that there are still following problems for existing scheme:
1, in single scene, vehicle (contain kinetic model), sensor model, traffic flow, road information are stored in same
In file, under normal circumstances, modifies any one of its and require to re-start matching, customized degree and spirit to other several
Activity is lower；
2, do not have automatic test ability, individual feature is tested, each scene needs are run one by one manually, greatly
Test is hindered fast and efficiently to carry out.
Summary of the invention
The object of the present invention is to provide a kind of scene management methods of DAS (Driver Assistant System), to solve in the prior art ask
Topic improves testing efficiency and flexibility.
The present invention provides a kind of scene management methods of DAS (Driver Assistant System), wherein includes:
It is based respectively on that Standard andRegulation, multiple scene databases are built in driving, field test, V2X, the scene of the accident naturally；
Data are selected to build multiple scene modules from multiple scene databases；
The multiple scene module is imported into test platform, after being defined to test result, is outputed test result.
Preferably, the test result include test pass through, test skip, test alarm, test crash, test malfunction or
Pending The Entry Into Force test.
It preferably, include vehicle parameter, sensor, traffic flow parameter or road parameters in the scene database.
Preferably, further includes: the test result is generated and is reported.
The scene management method of DAS (Driver Assistant System) provided by the invention is by establishing scene database, then from contextual data
It selects data to build scene module in library, scene module importing test platform is obtained into test result, compared with prior art,
Automatic test speed is greatly improved, the problems in test point can be efficiently identified, improve testing efficiency and spirit
Activity.
Detailed description of the invention
Fig. 1 is the flow chart of the scene management method of DAS (Driver Assistant System) provided in an embodiment of the present invention.

As shown in Figure 1, the embodiment of the invention provides a kind of scene management methods of DAS (Driver Assistant System), comprising:
S1, is based respectively on that Standard andRegulation, multiple scene databases are built in driving, field test, V2X, the scene of the accident naturally.
Scene is built based on statutory standard, is to expand with driving, V2X, traffic accident etc. naturally, will be formed checkout area
Each module of scape is stored in a manner of " data flow-database ".
It may include vehicle parameter, sensor, traffic flow parameter or road parameters etc. in the scene database.
S2 selects data to build multiple scene modules from multiple scene databases.
According to certain rule, the case stored in each module data hardship is combined, data are mutual in each database
It can be optionally combined, substantially reduce modeling demand and data management difficulty.
The multiple scene module is imported test platform, after being defined to test result, outputed test result by S3.
The test scene established will be chosen according to database and imports automatic test platform, and output result is made by oneself
Justice, it is preferable that export the result after the completion of test in the form of picture or report, preliminary test result may include
Test passes through, tests and skip, test alarm, test crash, test error or Pending The Entry Into Force test.
The scene management method of DAS (Driver Assistant System) provided in an embodiment of the present invention is by establishing scene database, then from field
It selects data to build scene module in scape database, scene module is imported into test platform to obtain test result, with existing skill
Art is compared, and automatic test speed is greatly improved, and can be efficiently identified the problems in test point, be improved testing efficiency
And flexibility.
Structure, feature and effect of the invention, the above institute are described in detail based on the embodiments shown in the drawings
Only presently preferred embodiments of the present invention is stated, but the present invention does not limit the scope of implementation as shown in the drawings, it is all according to structure of the invention
Think made change or equivalent example modified to equivalent change, when not going beyond the spirit of the description and the drawings,
It should all be within the scope of the present invention.
