Abstract

The present invention provides an automatic driving road test data analysis method and device, the method comprising: acquiring the CAN data corresponding to the moment when the driver actively takes over during the automatic driving, extracting key data from the CAN data in the automatic taking over scene, and obtaining the CAN data set ; Draw a scatter diagram according to the CAN data set, and perform regression curve fitting based on the scatter diagram to obtain the driver's initiative to take over the threshold model; according to the driver's initiative to take over the threshold model, generate vehicle AEB system under different driving conditions Action rules. This solution solves the problem of high cost of the existing threshold value test, can reduce the cost of threshold value extraction test, and guarantees the driving safety of the vehicle.

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...
