Vehicle information driving behaviors recording apparatus

Abstract

The invention discloses a recording device of vehicle driving behavior information. A device body of the recording device comprises a time recording part which comprises a G time unit for synchronizing with the GPS time; an M time unit for obtaining the time information of a vehicle; a speed recording part which comprises a G speed unit for matching the GPS to obtain the speed information of the vehicle; an M speed unit for obtaining the running speed information by the vehicle; a collision recording part which comprises a collision sensing unit for sensing collision of the vehicle; a judgment and processing part which is connected with all recording parts and receives the information from all recording parts to perform the judgment and processing work; and a record storage device which is connected with the judgment and processing part to store the driving behavior information records. The recording device of the vehicle driving behavior information records a piece of information per 0.1 second in the manner of being 0.75 second faster than the human body response, thus keeping the information with the best judging effect and accuracy for the identification and judgment of vehicle accidents.

Description

technical field [0001] The invention relates to a vehicle information driving behavior recording device. Background technique [0002] The development of industry and commerce, the heavy traffic, and the increasing number of vehicles have greatly increased the probability of accidents caused by various means of transportation. Although traveling by car has the advantage of being fast and convenient, however, the vehicle is bulky, heavy and moving at a fast speed. Such an object with huge inertia and momentum cannot immediately switch its path when driving. Please refer to Table 1 below: [0003] Table 1 is a reference table of driving speed and distance required for reaction. [0004] speed (KM / hr) distance traveled per minute (M / min) distance traveled per second (M / sec) reaction distance (M) 5 10 15 20 25 30 35 40 45 50 55 60 65 70 75 ...

AI Technical Summary

Problems solved by technology

[0007] The earliest driving recorder is the mechanical driving recorder used in Japan in 1960. Although the recorder has been continuously reformed and updated, it is limited by the inherent conditions of the mechanical type, and its mechanical accuracy and human disadvantages are difficult to overcome. , so it is easy to misjudgment, in view of this, the birth of digital driving recorder

[0008] For the digital recorder, please refer to Taiwan Patent Application No. 90108195, "Intelligent Driving Recording System and Method" Patent, and No. 93141052, "Curve Safety Warning and Driving Recording Method for Navigation System" patent. The above-mentioned patents are mainly It is to use GPS to measure the position and driving conditions of the vehicle, and record it for the identification of accidents; however, it is well known that the GPS used by ordinary people is a non-military GPS, and the accuracy of GPS used by civilians is limited. It may be of commercial value for driving navigation and route planning, but if private GPS alone is used as the basis for accident identification and judgment that requires a high degree of accuracy, its authenticity is open to question. If it does not cooperate with other sensing mechanisms, it will still be distorted possibility of

[0009] In the prior art, there is still such as China Taiwan Patent Application No. 94126583, "Driving Information Recording Device and System with Abnormal Vibration Detection Function", which mainly uses the content captured by the camera as driving information to record, and when there is abnormal vibration Store photographic content; however, when a vehicle collides, it is not specific to a certain direction or position. The direction and position that can be covered by installing cameras is limited, and increasing the number of cameras requires a corresponding increase in the number of processing and storage units and the cost, and the camera can only capture the state of the "external environment", and cannot effectively understand the driving state of the vehicle. Therefore, it is known that such existing cases are difficult to effectively provide the information required for accident identification

[0010] From the above, the accuracy of existing driving behavior recording devices is also limited, and there is still a need for improvement in practical aspects
