Processing method for vehicle driving data

Abstract

The invention discloses a processing method for vehicle driving data. The method comprises: an instrument panel template database is established according to a vehicle model; instrument panel image information during a vehicle driving process, image information in front of a driven vehicle, and vehicle state information are obtained in real time; a vehicle state is monitored; if the vehicle state is abnormal, the instrument panel image information is extracted and is compared with the instrument panel template database, vehicle velocity data and instrument panel indication signal data are identified, an image and driving data are generated by combining other information, gathering and storage are carried out, and alarm information is sent out; and if the vehicle state is determined to be a traffic accident state, driving data of an involved vehicle are extracted and an accident happening process is restored. According to the invention, an event occurring in a driving process is associated with a corresponding instrument panel image; and the image data can be used as visual evidences and can be used for regulation breaking determination or accident liability judgment.

Description

technical field [0001] The invention relates to the technical field of vehicle driving records and driving process restoration, in particular to a method for processing vehicle driving data. Background technique [0002] When special events, accidents or failures occur in the car, it is necessary to obtain driving data to record special events and analyze the causes of accidents or failures, but these driving data are difficult to obtain after the event. [0003] When the driver is driving, the main focus is on three aspects: the front view, the instrument panel, and the perception of the driving state of the vehicle (such as sound, vibration, etc.). In the existing systems, few of these three aspects of information will be aggregated and saved, and used to restore the driving process. Moreover, there are many indication information on the instrument panel and they are not universal. Many drivers can only recognize commonly used indication data, and often have no concept of...

In the existing systems, few of these three aspects of information will be aggregated and saved, and used to restore the driving process

Moreover, there are many indications on the instrument panel and they are not universal. Many drivers can only recognize the commonly used indication data. They often have no concept of special fault prompts or ignore these prompts.

[0004] In addition, the GPS positioning system is often used for positioning of existing vehicles, but due to the low positioning accuracy of GPS, there are stability problems in the GPS signal during vehicle movement, which makes the continuity and reliability of the data not high enough

[0005] Most of the existing schemes use electronic data as a reference, but electronic data cannot be used as intuitive evidence; due to the different types and models of vehicles, there is currently no simple general-purpose device that can accurately record the driving status of vehicles. In the event of an event or accident, complete evidence cannot be preserved, and the state of the vehicle at that time cannot be fully reproduced
