Co-driving autonomous vehicles have manual and automated driving mode.The driving behavior characteristics of co-driving autonomous vehicles will show new characteristics.The driving behavior data of 15 drivers are collected.The characteristic map of driving behavior is constructed by using symbol aggregation approximation method and video recording calibration method.The common behavior sequence of autonomous vehicle man-machine takeover is excavated based on longest common subsequence algorithm.The results show that when obstacles appear in front of the autonomous vehicle the common behavior sequence is:looking ahead and pressing the brake pedal-observing the left rearview mirror and turning on the left turn signal-turning the steering wheel to the left-closing left turn signal.This study may helpful to improve the effectiveness of autonomous vehicle takeover.
