Embodiment Construction

[0029] Such as figure 1 As shown, the track segmentation method of a kind of vehicle travel recorder of the present invention adopts a perfect "end-pipe-cloud" three-layer architecture; it comprises the following steps:

[0030] Step 1: The vehicle-mounted terminal collects the historical trajectory data of the vehicle, and uploads the historical trajectory data to the Internet of Vehicles cloud platform through the Internet of Vehicles, and the cloud platform of the Internet of Vehicles determines which segmentation method to use; the historical trajectory data of the vehicle is the vehicle ignition One or more of flameout event data, ACC status data, and GPS behavior data;

[0031] Step 2: the Internet of Vehicles cloud platform judges whether to meet the condition of the auxiliary segment: yes, then execute step 3; no, then execute step 4; the condition of the auxiliary segment includes: within a set time, the vehicle-mounted terminal continuously uploads the ignition Flam...

Abstract

The invention relates to an automobile driving recorder locus segmentation method and belongs to the field of automobile driving historical locus recording in a vehicle network system. The method utilizes an improved terminal-tube-cloud three layer structure and realizes automobile driving historical locus segmentation according to a vehicle ignition loss event, an ACC state and GPS behavior characteristics. Different vehicle terminals dynamically select segmentation methods according to a vehicle state. Through combination with three auxiliary segmentation methods such as timeout segmentation, forced segmentation and zero segmentation, the segment data is uploaded to a database of a car networking cloud platform in real time and a user can inquire detailed segment information.

Description

technical field [0001] The invention belongs to the field of vehicle driving history track recording in a vehicle networking system, and in particular relates to a track segmentation method of a vehicle driving recorder. Background technique [0002] With the continuous development of science and technology, the car networking system has become the development direction of the future car network. The Internet of Vehicles is a huge interactive network composed of information such as vehicle location, speed, and route. From the perspective of the network, the Internet of Vehicles system is a three-layer system of "device, pipe, and cloud". [0003] The first layer (end system): "end" is the interaction and display mode between people and cars, people and clouds, cars and roads, and cars and cars. Allowing users to display and experience the Internet of Vehicles functions through smart terminals or Apps is a necessary form of all application values; [0004] The second layer ...
