Vehicle driving data recording system

Abstract

The invention discloses a vehicle driving data recording system. An instrument panel camera shoots the images of an instrument panel in real time during driving of a vehicle; a forward-visual-angle camera shoots the images of places in front of the vehicle in real time during driving of the vehicle; a vehicle-mounted sensor acquires the information about a vehicle state in real time during driving of the vehicle; a data processing module is equipped with an instrument panel template database and an alarm module; the images acquired by the instrument panel camera are transmitted to the data processing module for comparison with data in the instrument panel template database so as to recognize vehicle velocity data and instrument panel indication signal data; and the data processing module carries out summarization, processing and storage on the basis of front images transmitted by the forward-visual-angle camera and the vehicle state information transmitted by the vehicle-mounted sensor, and calls the alarm module when the vehicle state is abnormal, and when the vehicle has a traffic accident, the data processing module calls a scene reproducing and simulating module to reproduce the process of occurrence of the accident.

Description

technical field [0001] The invention relates to the technical field of vehicle driving records, in particular to a vehicle driving data recording system. 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 special fault prompts or ignore thes...

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
