Description

Technical Field

[0002] The electronic rearview mirror system is an important component of the assisted driving system. It is mainly used to replace the traditional glass mirror and reduce the blind spot of the vehicle. The system can be regarded as a "camera-display screen" model, which uses the camera to collect the surrounding field of view of the vehicle body and provides the driver with the surrounding field of view information of the vehicle through the display screen, thereby realizing the function of the traditional physical mirror. The advantages of the electronic rearview mirror system include: a wider range of driving field of view images, fewer blind spots, and the driver can grasp more road information; lower wind resistance can reduce the fuel consumption of the whole vehicle by 1%-2%.

[0003] Sentry mode, also known as the remote monitoring function, allows car owners to use their mobile phones to browse the video images captured by the cameras around the car body in real time after the car is parked. If the vehicle is hit or moved, the external camera will immediately record the surrounding environment and send a reminder to the car owner through the mobile phone application or SMS. The in-vehicle system can also play back the relevant video. In addition, the car owner can also use the mobile phone to perform remote operations, such as triggering the vehicle to honk, flash the lights, and make remote calls. Summary of the invention
