Embodiment Construction
[0019] 1. The source of vehicle operation data is the vehicle fault diagnosis port (OBD) and the onboard multi-directional acceleration sensing module.
[0020] 2. Adopt plug-in double data storage unit, short-term storage unit has small capacity, high frequency of data reading and writing, and long-life E2PROM memory; long-term storage unit has low reading and writing frequency, large amount of data and long retention time , using FLASH large-capacity memory.
[0021] 3. The upper computer is equipped with a dedicated card reader to read the data of the storage unit.
[0022] 4. Develop special data analysis software.

The invention relates to an automobile operating parameter recorder based on OBD communication technology. A specific automobile kinetic model is built and used for analysis to obtain automobile operating parameters, and further, operation input parameters of a driver are analyzed. Through a data analysis upper computer and analysis software which are related with the recorder, automobile operating data remaining in a memory unit can be read for data analysis. Through the kinematic and dynamic theories, the recorded data are utilized to analyze and obtain the automobile running state and operation actions of the driver. Road interference can be identified and eliminated. In case of continuous interference (such as upward and downward slopes), the automobile enters a new running state; in case of accidental interference (such as pits on roads), the automobile suddenly changes the running state and then returns to the original state. The accidental interference is relatively complicated and relatively difficult to judge, and enough tests are required for verification.
Description
[0001] technical field [0002] The vehicle operating parameter recorder is a "black box" used to record important data during the operation of the vehicle. Its recording method is "overflow", which only retains the latest data and automatically overwrites outdated data. Background technique [0003] With the rapid increase of car ownership, road traffic accidents are increasing day by day, and many traffic accidents cannot accurately determine the cause and determine the responsibility. Since the accident scene caused by the traffic accident is identified as the only basis for the allocation of accident responsibilities, various human and non-human interferences cause the traffic police to lack strong evidence when judging the cause of the accident and analyzing the responsibility. Reliability is often questioned. Illegal acts such as falsifying the accident scene, destroying the accident scene, and transferring the accident scene occur from time to time. The applicatio...
