Vehicle collision detection method and system based on vehicle-mounted intelligent terminal

Abstract

The invention discloses a vehicle collision detection method and system based on a vehicle-mounted intelligent terminal. The method comprises the following steps: the vehicle-mounted intelligent terminal acquiring driving data in the driving process in real time, transmitting the driving data to a background server in real time, and then the vehicle-mounted intelligent terminal judging whether the collision occurs according to the change of the driving data; when detecting that the change value of the driving data is greater than a predetermined value, the vehicle-mounted intelligent terminal judging that that the collision occurs at present, acquiring a preset processing mode to primarily process the vehicle-mounted intelligent terminal; the background generating a final judgment result, and feeding back to the vehicle-mounted intelligent terminal; when detecting that the final judgment result and the primary judgment result are inconsistent, the vehicle-mounted intelligent terminal correcting the current primary processing operation. Through the adoption of the method and system disclosed by the invention, the error reporting can be reduced, the condition that disc volume is fully occupied since the video is frequently locked in the driving record is avoided; the detection accuracy is improved, the available information can be immediately obtained, and the collision can be immediately processed.

Description

technical field [0001] The invention relates to the technical field of intelligent vehicle equipment, in particular to a vehicle collision detection method and system based on a vehicle intelligent terminal. Background technique [0002] At present, many vehicle-mounted intelligent terminals such as driving records and rearview mirrors on the market support the collision detection function. When a vehicle collision is detected, it will initiate a video recording lock or send the information to the vehicle owner or the preset notification object in the form of a warning. However, the current solutions generally have the problem of high false positive rate and missed negative. Once the false positive rate is high, it will lead to a great waste of resources. Once the false positive rate is missed, the purpose of detection will not be achieved. [0003] Therefore, the prior art still needs to be improved and developed. Contents of the invention [0004] In view of the deficie...

Problems solved by technology

[0004] In view of the deficiencies in the prior art, the purpose of the present invention is to provide a vehicle collision detection method and system based on a vehicle-mounted intelligent terminal, aiming to solve the problem of high false alarm rate and missed report in vehicle collision detection in the prior art. A high reporting rate will lead to a great waste of resources. Once a false report is missed, the purpose of detection will not be achieved.
