Title:
DRIVING BEHAVIOR ANALYSIS METHOD AND DEVICE
Document Type and Number:
WIPO Patent Application WO/2016/086792
Kind Code:
A1
Abstract:
A driving behavior analysis method and device, the method comprising the following steps: reading vehicle acceleration vector data and angular velocity vector data detected by a sensor in a traveling process of a vehicle (S101); projecting the acceleration vector data and the angular velocity vector data onto a traveling coordinate system (x', y', z'), and acquiring acceleration vector data and angular velocity vector data in the traveling coordinate system (S102); selecting, from the vector data in the traveling coordinate system, an acceleration sample data set and/or an angular velocity sample data set when a driving behavior changes (S103); comparing the acceleration vector data in the acceleration sample data set with a preset acceleration reference value and a preset deceleration reference value, and determining whether an acceleration behavior or a brake behavior has occurred (S104); and comparing the angular velocity vector data in the angular velocity sample data set with a preset angular velocity reference data sequence, and determining whether a left turn behavior, a right turn behavior, a left merging behavior or a right merging behavior has occurred (S105). Since an acceleration reference value, a deceleration reference value and an angular velocity reference data sequence are configured, the present invention can accurately determine two types of changes in driving behavior.
