Embodiment 1

[0018] A method for monitoring a scene outside a vehicle in a parking state, comprising the following content:

[0019] When the CAN bus in the car is in the wake-up state, the driving recorder is correspondingly in the wake-up state when it is powered on. At this time, the driving recorder exchanges information with the vehicle through the WIFI interface, or communicates with other CAN nodes of the vehicle through the CAN bus. Interaction; during the information interaction process, if the CAN bus meets the network sleep conditions, the driving recorder will enter the network sleep state;

[0020] When the CAN bus in the car is in sleep state, any one of the following conditions must be met in order to keep the driving recorder in the local wake-up state, that is, the local working state:

[0021] 1. After the driving recorder enters the network sleep state, it does not receive the local sleep command sent by the upper application, so the driving recorder is in the local wake...

Embodiment 2

[0025] A method for monitoring a scene outside a vehicle in a parking state, comprising the following content:

[0026] When the CAN bus in the car is in the wake-up state when it is powered on, the car machine is in the local wake-up state when it is powered on. At this time, the car machine communicates with the built-in controller of the driving recorder through wireless signals; If the CAN bus sends a message to control the vehicle to stop sending wireless signals to the built-in controller of the driving recorder, the built-in controller of the driving recorder will be powered off and stop working, making the driving recorder in a local sleep state;

[0027] When the CAN bus in the car is in the power-off sleep state, any of the following conditions must be met to keep the driving recorder in the local wake-up and power-on working state:

[0028] When the CAN bus in the car is in the wake-up state, the driving recorder is correspondingly in the wake-up state when it is po...

Abstract

The invention belongs to the technical field of safe driving assistance, and particularly relates to a method for monitoring a scene outside a vehicle in a parking state. Image information outside a vehicle is collected through a camera of the automobile data recorder, the image information is displayed, coded and stored, and the automobile data recorder is connected with the vehicle machine through WIFI and transmits video information, so that the automobile data recorder can still shoot images after the vehicle is parked; and the vehicle owner is ensured to collect the vehicle damage evidence when leaving the vehicle.

Description

technical field [0001] The invention belongs to the technical field of safety driving assistance, and in particular relates to a method for monitoring scenes outside a vehicle in a parking state. Background technique [0002] Drive recorder is the instrument of the relevent informations such as image and sound in registration of vehicle traveling way. Driving recording is installed After instrument, the video image and sound of running car overall process can be recorded, evidence can be provided for traffic accident. At the same time, the time, speed, location, and related operations of the driver on the vehicle are all recorded in the video, which is quite a "black box". However, the driving recorder will stop working after parking, and there is no guarantee that the owner will collect evidence of vehicle damage when leaving the vehicle. Contents of the invention [0003] In order to overcome the above-mentioned problems, the present invention provides a method for mon...
