no. 1 example

[0050] see figure 1 , which is a flow chart of an advanced driving assistance system function testing method provided in Embodiment 1 of the present application.

[0051] Such as figure 1 As shown, the testing method of the advanced driving assistance system function provided by this embodiment includes:

[0052] Step S102, acquiring road test data of the road test vehicle, the road test data including CAN bus data and ADAS sensor data.

[0053]In this embodiment, the CAN bus data includes controller area network (CAN for short) bus data of the road test vehicle. The ADAS sensor data includes sensor data of the advanced driving assistance system of the road test vehicle, such as lidar data, camera data, and the like.

[0054] In a specific implementation manner, the CAN bus data and the ADAS sensor data can be collected respectively by using a CAN card and a data fusion acquisition industrial computer. Of course, in other embodiments, other methods can also be used to obtai...

no. 2 example

[0065] see figure 2 , which is a flow chart of an advanced driving assistance system function testing method provided in Embodiment 2 of the present application. The method for testing the functions of the advanced driving assistance system provided in this embodiment includes the aforementioned steps S102 to S106.

[0066] Such as figure 2 As shown, in this embodiment, the step S102 is specifically: collecting and fusing the CAN bus data and ADAS sensor data to obtain the road test data of the road test vehicle.

[0067] In this embodiment, since the sources of the CAN bus data and the ADAS sensor data are different, the data format of the two types of data and the time stamp of the collected data may also be different, which will occur when the road test data is calculated. Can't handle it. Therefore, fusion processing is performed on the CAN bus data and the ADAS sensor data, and the formats and time stamps of the two data are unified to obtain the road test data, whic...

no. 3 example

[0072] see image 3 , which is a flow chart of an advanced driving assistance system function testing method provided in Embodiment 3 of the present application. The method for testing the functions of the advanced driving assistance system provided in this embodiment includes the aforementioned steps S102 to S106.

[0073] Wherein, step S102 may adopt the implementation manner described in Embodiment 2, or other implementation manners.

[0074] Such as image 3 As shown, in this embodiment, before the step S104, the method further includes:

[0075] Step S103 , performing a preprocessing operation on the road test data to remove non-numerical dead pixels and / or small bump data in the road test data.

[0076] In this embodiment, some blank spots may appear during data collection, and letters or symbols are displayed instead of numbers in the road test data. Therefore, by performing a preprocessing operation on the road test data, the non-numerical bad points in the road te...

Abstract

The invention discloses a method and device for testing the function of an advanced driving assistance system; the method comprises the steps: obtaining the road test data of a road test vehicle, andenabling the road test data to comprise CAN bus data and ADAS sensor data; and calculating the road test data according to a problem model, screening out problem data in the road test data, and generating a test result of the advanced driving assistance system function of the road test vehicle according to the problem data. When the functions of the advanced driving assistance system are tested, CAN bus data and ADAS sensor data are utilized, so that the utilization rate of the ADAS sensor data is increased, and the test result is more accurate.

Description

technical field [0001] The present application relates to the technical field of data processing, in particular to a testing method and testing device for functions of an advanced driving assistance system. Background technique [0002] Intelligent Connected Vehicle, or ICV (full name Intelligent Connected Vehicle), refers to a new generation of vehicles that are organically combined with the Internet of Vehicles and smart vehicles. All kinds of sensors on the car sense the surrounding environment at any time during the driving process, collect data, and combine the navigator map data to perform systematic calculation and analysis, determine the road conditions according to the analysis results, and increase the safety of car driving sex. Therefore, ADAS needs to be functionally tested before mass production to ensure the safety of the driving process. [0003] In the prior art, when performing functional tests on ADAS, most of the test results are judged based on the driv...
