However, it will be appreciated by those of ordinary skill in the art that numerous technical details are set forth in order to provide a better understanding of the present application in various embodiments of the present invention. However, the technical solution claimed in the present application can be implemented without these technical details and various changes and modifications based on the following embodiments.
A first embodiment of the present invention relates to a driving record assist device, as shown in fig. 1, including: a serial port connector 11 for connection to a tachograph, a processor 12 connected to the serial port connector 11, and a first sensor 13 connected to the processor 12. The first sensor 13 is used for detecting first vibration data of the vehicle after the vehicle is turned off and the automobile data recorder is dormant; the processor 12 is used for judging whether the vehicle is in collision or not according to the first vibration data after the vehicle is flameout, and sending the first vibration data to the automobile data recorder through the serial port connector 11 when the vehicle is judged to be in collision, so that the automobile data recorder stores the first vibration data locally or uploads the first vibration data to the server.
Because the first sensor 13 is used for detecting the first vibration data of the vehicle after the vehicle is turned off and the automobile data recorder is in a dormant state, the processor 12 is used for judging whether the vehicle is collided or not according to the first vibration data after the vehicle is turned off, so that the collision can be timely detected when the automobile data recorder is in the dormant state. Meanwhile, the processor 12 is further configured to send the first vibration data to the automobile data recorder through the serial port connector 11 when it is determined that the vehicle has a collision, so that the automobile data recorder stores the first vibration data locally or uploads the first vibration data to the server, and then the data before the collision can be acquired locally from the automobile data recorder or from the server, which is beneficial to accident analysis so as to restore the situation of the collision event.
The first sensor 13 may be an acceleration sensor, the acceleration sensor is configured to detect acceleration data of the vehicle, and the first vibration data is acceleration data of the vehicle. Specifically, X, Y and Z parameter thresholds of the acceleration data are configured by default, and when the parameter change is larger than a set range, the collision is determined.
Optionally, the driving recording assisting device may further include a memory 14 connected to the processor 12, and the processor 12 is configured to obtain parking position information, which is sent by the driving recorder when the vehicle is turned off and the driving recorder is in sleep state, via the serial port connector 11 before the vehicle is turned off and the driving recorder is in sleep state, and send the parking position information to the memory 14 for storage. The processor 12 is further configured to synthesize the first vibration data and the parking position information into a message, and send the message to the automobile data recorder through the serial port connector 11, so that the complete message is received by the automobile data recorder, and the collision event data is more conveniently stored and uploaded.
In practical application, when the vehicle is turned off and the automobile data recorder is in a sleep state, the processor 12 enters a low-power-consumption running state, controls the first sensor 13 to detect the first vibration data of the vehicle once every preset time period, and circularly caches the first vibration data into the memory 14, so as to ensure that the first vibration data in the memory 14 is the latest data in a period of time.
Further, the processor 12 is specifically configured to synthesize the first vibration data from a first preset time before the collision occurs to a second preset time after the collision ends and the parking position information into a message, and send the message to the automobile data recorder through the serial port connector 11, where the first preset time and the second preset time may both be positive numbers, or any one of the first preset time and the second preset time may be zero, and this is not limited here. When the driving record auxiliary devices are all positive numbers, the data related to the collision event before and after the collision can be obtained, so that the accident analysis can be more accurately carried out so as to restore the situations before and after the collision event.
In order to provide more accurate accident analysis data, the processor 12 may also be used to wake up the tachograph via the serial port connector 11 after a vehicle collision to turn on the tachograph for image capture. The automobile data recorder can also store the shot monitoring data to the local or upload the data to the server, so that the monitoring data after the vehicle is collided can be obtained subsequently.
