Problems solved by technology

[0010] In addition, the GPS positioning system is commonly used in existing vehicles to locate and judge the driving status of the vehicle. However, due to the low positioning accuracy of GPS, there are stability problems in the GPS signal during the movement of the vehicle, which makes the continuity and reliability of the data not high enough.
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

Embodiment 1

[0062] Embodiment 1: as figure 2 As shown, according to the size and structure of the instrument panel of the vehicle, the instrument panel camera 2 is set on the support seat of the steering wheel 5. When the instrument panel is wide or scattered, one instrument panel camera cannot take a complete image of the instrument panel, and multiple Dashboard camera 2 respectively captures different parts of the dashboard image; installs forward perspective camera 4 on the vehicle; sets angular velocity sensor 6, shock sensor 7, acceleration sensor 8, gyroscope sensor 9, speed pulse sensor 10, angular velocity sensor The sensor 6 is installed on the steering wheel 5 of the vehicle to detect the rotation angle of the steering wheel 5. The vibration sensor 7 is used to detect the driving state of the vehicle and abnormal vibrations and vibrations. The acceleration sensor 8 collects the acceleration information of the vehicle. The gyroscope sensor 9 Collect vehicle steering data, speed ...

Embodiment 2

[0121] Embodiment 2: the system provided by the application can also be applied in driving learning and driving test. At this time, the vehicle-mounted instruction issuing device 22, the control center 24, the vehicle-mounted camera, the control center and the vehicle-mounted instruction issuing device, and the data processing module are added in the system. Wirelessly connected, the data processing module is connected to the vehicle-mounted camera and the vehicle-mounted instruction issuing device respectively, and the vehicle-mounted instruction issuing device 22 is arranged on the vehicle 21, and is used to issue driving instructions through voice prompts or text display; the vehicle-mounted camera includes The exterior cameras 23a, 23b, 23c, 23d of the scene and the interior cameras 23e, 23f for photographing the scene inside the car, 23a, 23b are used for photographing the road conditions in front of the vehicle, 23c, 23d are used for photographing the side and rear road co...

Abstract

The invention discloses a general-purpose vehicle driving data recording system. The general-purpose vehicle driving data recording system comprises an instrument panel camera, a frontward view-angle camera, a vehicle-mounted sensor, a data processing module and a field recovery module, wherein the instrument panel camera is used for photographing instrument panel image information in a vehicle driving process in real time; the frontward view-angle camera is used for photographing frontward image information in the vehicle driving process in real time; the vehicle-mounted sensor is used for acquiring vehicle state information in the vehicle driving process in real time; an instrument panel database is loaded in the data processing module, and the data processing module is used for comparing with the instrument panel image information transmitted by the instrument panel camera; the data processing module is used for monitoring a vehicle state according to the instrument panel image information, the frontward image information and the vehicle state information; when the vehicle state is abnormal, the data processing module is used for carrying out collection processing and preserving the obtained information and outputting an alarming signal; the field recovery module is used for determining an accident occurrence key time point according to instrument panel real-time information data and the vehicle state information, which are transmitted by the data processing module when a vehicle is subjected to a traffic accident; an accident panoramic image is recovered by utilizing the frontward image information at the key time point.

Description

technical field [0001] The invention relates to the technical field of vehicle driving record and driving process restoration, in particular to a general-purpose vehicle driving data recording system and processing method. 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 system, few of these three aspects of information are aggregated and saved, and used for driving process restoration. Moreover, there are many indications on the instrument panel and they are not universal. Many drivers can only recognize commonly used indication data. They often ...
