Embodiment Construction

[0017] combine figure 1 Describe this embodiment, a method for automatically video recording and taking pictures after a vehicle collides, the method is implemented by the following steps:

[0018] Step A. When T-BOX receives the collision signal from ACU in the non-OFF state, it immediately reports to TSP, and requests the Ecall number from the TSP background with the Ecall identification bit (1min to identify a collision signal is valid);

[0019] Step B. T-BOX sends out a wake-up AVN signal, so that the AVN of the M171 central control host starts the MCU, and periodically sends a collision emergency "photograph + video 10S" command with an event ID for 1 minute; that is: Tbox_CrashPhotoRequest=0x1:Request lasts 1min; execute step C;

[0020] Step C, AVN power management identifies whether the power-on is successful, if yes, the AVN forcibly turns on the camera after receiving the event-type camera command signal, and executes step D; if not, executes step E;

[0021] Step...

Abstract

The invention discloses a method for automatically recording and photographing after vehicle collision, relates to the technical field of new energy vehicle safety, and solves the problems that in the prior art, vehicle accidents cannot be handled in time, the severity degree of accident sites is caused, and the like. Vehicle collision signals are collected in real time through a hardware vehicle-mounted terminal TBOX, the position, the vehicle speed and gear information of a vehicle are uploaded in real time, when the vehicle collides, a vehicle-mounted module TBOX receives collision sign signals, the TBOX automatically sends a photographing instruction to a vehicle machine AVN, the AVN executes a camera to photograph a picture, the picture is photographed and recorded for 10S, and the vehicle-mounted terminal TBOX automatically sends the photographing instruction to the vehicle machine AVN. And the video and photo display can be automatically popped up when the video and photo are uploaded to the cloud. According to the method disclosed by the invention, a call judgment condition after collision is added, the safety of the vehicle is ensured, and automatic ECALL call can be realized after photographing if a traffic accident occurs.

Description

technical field [0001] The invention relates to the field of new energy vehicle safety technology. Through the interaction between the vehicle-mounted terminal TBOX of the new energy vehicle, the airbag ACU and the AVN camera of the vehicle, it is specifically a method for realizing automatic video recording and photographing of the vehicle after a collision. Background technique [0002] Nowadays, there are more and more vehicles, leading to frequent vehicle traffic accidents. When a major vehicle accident occurs, the rescue department cannot timely understand the severity of the accident scene, resulting in a lot of time wasting and missing the best time for life rescue. In order to deal with this problem, the present invention implements a method for automatic video recording and remote photographing of the vehicle when the vehicle is in an accident and the airbag is bumped and ejected. Contents of the invention [0003] In order to solve the problems that the prior art...
