Abstract

The invention provides an automatic driving drive test data analysis method and device, and the method comprises the steps: obtaining CAN data corresponding to an active takeover moment of a driver inautomatic driving, carrying out the key data extraction of the CAN data in an automatic takeover scene, and obtaining a CAN data set; drawing a scatter diagram according to the CAN data set, and performing regression curve fitting based on the scatter diagram to obtain a driver active takeover threshold model; and generating vehicle AEB braking rules under different driving conditions according to the driver active takeover threshold model. According to the scheme, the problem of high cost of the existing threshold test is solved, the threshold extraction test cost can be reduced, and the vehicle driving safety is guaranteed.

Description

technical field [0001] The invention relates to the field of automatic driving, in particular to a method and device for analyzing road test data of automatic driving. Background technique [0002] With the maturity of automatic driving technology, in many scenarios, the driver can be separated from manual driving, but in some potentially dangerous scenarios, active takeover is still required. Excessive active takeover will not only affect the driving experience, but may also bring potential danger. [0003] The current automatic driving system usually adopts the method of pre-setting the dangerous threshold to actively take over the judgment. When the driving parameters of the vehicle reach the dangerous threshold, it will remind the driver to take over, or automatically adjust the brakes. However, the setting of the danger threshold requires a large amount of test data, and it also needs to be adjusted and corrected according to the surrounding scene environment, which wi...
