Embodiment Construction

[0029] The technical solution of the present invention will be further described below in conjunction with the accompanying drawings.

[0030] The data collected by the three-axis acceleration sensor includes X, Y, and Z three-axis data, wherein the Y axis is the forward direction of the vehicle. X is the horizontal direction perpendicular to the Y axis. The Z axis is an up and down direction perpendicular to the XY plane. The three-axis data will be deviated due to the installation position and elevation angle of the vehicle. Therefore, it is necessary to automatically calibrate the three-axis data, and carry out multiple real-vehicle data collection according to the usual driving habits through the test of the real vehicle.

[0031] The driving behavior analysis method of the present invention tracks the signal curve of the three-axis accelerometer, when the curve area of ​​the X-axis signal of the three-axis accelerometer is greater than the reference value a, and the abs...

Abstract

The invention provides a driving behavior analysis method. The method comprises the following steps: tracking the signal curve of a triaxial accelerometer, and recording sharp turn when the curve area of the X-axial signal of the triaxial accelerometer is greater than a reference value a and the absolute value of a headstock angle difference detected by a GPS is greater than or equal to a reference value b; and recording fast lane change when the headstock angle difference detected by the GPS is smaller than the reference value b. The driving behavior is analyzed through adopting a triaxial accelerometer sensor and the GPS which are arranged on the vehicle in the driving behavior analysis method, so extra installation of an OBD device is not needed, and the cost is low.

Description

technical field [0001] The invention relates to a driving behavior analysis method, which belongs to the field of automobile safety. Background technique [0002] In the current after-loader products, the function of providing driving behavior analysis has become a basic requirement, and the prerequisite for realizing this function is the support of vehicle data. At present, most of the technical solutions are realized by adding an OBD data acquisition module. However, due to the age of the vehicle and the variety of brands, it is impossible to solve the problem of obtaining vehicle data in the vehicles of all potential installation users, and not all users are willing to choose add-on parts. Contents of the invention [0003] The purpose of the present invention is to mention that the present invention has adopted following technical scheme: [0004] A driving behavior analysis method, characterized in that it comprises the following steps: tracking the signal curve of ...
