[0002] The electronic rearview mirror is a system composed of a camera and a monitor. It needs to see the rear and side views of the vehicle clearly within the specified field of view. It is a new type of indirect vision device. The new version of the GB15084 standard calls it a "camera-monitor system", abbreviated as CMS.

[0003] Commonly used electronic rearview mirror systems are usually equipped with two cameras and two display screens, with one camera and one display screen on each side. The cameras collect information from the rear and both sides of the vehicle and display it on the display screens. The main controller processes the information collected by the cameras in real time.

[0004] When an electronic rearview mirror observes a dangerous situation, it is usually displayed on the main screen and cannot intuitively notify the driver. Utility Model Content

[0005] The purpose of the utility model is to provide an electronic rearview mirror with integrated atmosphere lights to solve the technical problem in the prior art that when a dangerous situation is detected, the main driver cannot be notified intuitively. In order to solve the above technical problems, the utility model provides an electronic rearview mirror with integrated atmosphere lights. When a dangerous situation is detected, the atmosphere lights flash to intuitively remind the driver of the danger. In addition, it can also monitor the personnel to turn on the welcome mode, making the functions of the atmosphere lights diversified.

[0006] The utility model provides an electronic rearview mirror with integrated atmosphere light, comprising:

[0007] CMS control module, left camera, left screen, left ambient light strip, right camera, right screen, right ambient light strip and LED control module, the left camera and the right camera are respectively located at the left rearview mirror and the right rearview mirror of the vehicle, the left screen and the left ambient light strip are spaced apart and are both located at the left front end of the vehicle, the right screen and the right ambient light strip are spaced apart and are both located at the right front end of the vehicle,

[0008] The right camera, the right screen, the left camera, and the left screen are all connected to the CMS control module, and the right atmosphere light strip and the left atmosphere light strip are both connected to the CMS control module through an LED control module.

[0009] Furthermore, the left camera and the right camera collect information from both sides and the rear of the vehicle and transmit the information to the CMS control module. When the CMS control module determines that the information is dangerous, it controls the left and right ambient light strips to enter the attention mode.

[0010] Furthermore, the electronic rearview mirror with integrated ambient light also includes a main screen, which is arranged in the middle of the center console. The main screen is connected to the CMS control module. When the CMS control module determines that it is dangerous information, it controls the left ambient light strip and the right ambient light strip to enter the attention mode and prompts the dangerous information on the main screen.

[0011] Furthermore, when the vehicle is in the starting mode, the left camera or the right camera detects a person approaching the door, and the CMS control module controls the left ambient light strip and the right ambient light to enter the welcome mode.

[0012] Furthermore, when the vehicle is in parking mode, when the left camera or the right camera captures people, vehicles and objects approaching the vehicle, the CMS control module controls the left ambient light strip and the right ambient light strip to enter the attention mode.

[0013] Furthermore, when parking and entering sentry mode, if the left camera or the right camera detects that a person touches the vehicle and stays there for more than a preset time T, the CMS control module controls the left and right ambient light strips to enter attention mode.

[0014] Furthermore, the time T is 30 seconds.

[0015] Furthermore, the left ambient light strip and the right ambient light strip include a welcoming mode and an attention mode. The welcoming mode is that the light strip is lit in a flowing manner, and the attention mode is that the light strip flashes.

[0016] Furthermore, the attention mode includes a plurality of flashing frequencies, and the flashing frequency corresponding to the urgent reminder items is higher than the flashing frequency corresponding to the gentle reminder items.

[0017] Furthermore, the CMS control module communicates with the vehicle communication system via a CAN transceiver.

[0018] The CMS control module equipped in the electronic rearview mirror processes the information generated by the camera, and the computing power of the CMS control module will be partially idle. The electronic rearview mirror with integrated atmosphere light of the utility model connects the CMS control module with the atmosphere light, and uses the idle computing power of the CMS control module to control the atmosphere light, while making the functions of the atmosphere light diversified.

[0019] More specifically, it monitors information outside the vehicle in real time. When encountering danger while driving, the danger warning can appear on the main screen and notify the driver through the flashing of the ambient light strip; when the vehicle is started, the camera detects that a person is approaching the door and controls the ambient light to enter the welcome mode. When parking, when the camera detects that a person, vehicle or object is approaching, the controller will control the ambient light to flash to notify the driver to pay attention; when parking, when entering the sentry mode, if it detects that a suspicious person is approaching and touching the vehicle body and stays for too long, the ambient light will be controlled to flash to remind the suspicious person to stay away; the owner can freely choose the flashing color of the ambient light, the flashing interval, and the total flashing time. The flashing time in an emergency has a minimum value and cannot be modified

[0034] In order to make the purpose, technical solution and advantages of the embodiments of the utility model clearer, the technical solution of the utility model will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0035] like Figures 1 to 10 As shown, the utility model provides an electronic rearview mirror with integrated ambient light, comprising:

[0036] CMS control module 1, left camera 2, left screen 3, left atmosphere light strip 4, right camera 5, right screen 6, right atmosphere light strip 7 and LED control module 8. The left camera 2 and the right camera 5 are respectively located at the left rearview mirror and the right rearview mirror of the vehicle. The left screen 3 and the left atmosphere light strip 4 are spaced apart and are both located on the left front end inside the vehicle. The right screen 6 and the right atmosphere light strip 7 are spaced apart and are both located on the right front end inside the vehicle. The right camera 5, the right screen 6, the left camera 2 and the left screen 3 are all connected to the CMS control module 1. The right atmosphere light strip 7 and the left atmosphere light strip 4 are all connected to the CMS control module 1 through the LED control module 8.

[0037] The left camera 2 and the right camera 5 collect information from the rear and both sides of the vehicle. The CMS control module 1 is a system information processing module. After being processed by the CMS control module 1, the information is displayed on the left screen 3 and the right screen 6 for the driver to watch. The screen can be an OLED screen. Generally, the CMS control module processes the information generated by the camera, and the computing power of the CMS control module will be partially idle. The electronic rearview mirror with integrated atmosphere light of the utility model connects the CMS control module with the atmosphere light, and uses the idle computing power of the CMS control module to control the atmosphere light, while making the functions of the atmosphere light diversified.

[0038] The left camera 2 and the right camera 5 collect information on both sides and the rear of the vehicle and transmit the information to the CMS control module 1. When the CMS control module 1 determines that it is dangerous information, it controls the left ambient light strip 4 and the right ambient light strip 7 to enter the attention mode. Dangerous information can be that the surrounding vehicles or people are close to the vehicle, and the attention mode can be that the light strip flashes.

[0039] The electronic rearview mirror with integrated ambient light also includes a main screen 9, which is arranged in the middle of the center console. The main screen 9 is connected to the CMS control module 1. When the CMS control module 1 determines that it is dangerous information, it controls the left ambient light strip 4 and the right ambient light strip 7 to enter the attention mode, and prompts the dangerous information on the main screen 9. The driver is reminded through the main screen 9 and the light strip at the same time, so that the driver can receive intuitive danger prompts.

[0040] When the vehicle is in the starting mode, the left camera 2 or the right camera 5 captures a person approaching the door, and the CMS control module 1 controls the left ambient light strip 4 and the right ambient light to enter the welcome mode, and the welcome mode can be that the light strips are lit in a flowing manner.

[0041] When the vehicle is in parking mode, when the left camera 2 or the right camera 5 captures people, vehicles and objects approaching the vehicle, the CMS control module 1 controls the left ambient light strip 4 and the right ambient light strip 7 to enter the attention mode. The attention mode may include flashing of multiple frequencies. When the precautions are more urgent, the flashing frequency of the light strip is faster. When the precautions are more gentle, the flashing frequency of the light strip is slower.

[0042] Car owners can freely choose the flashing color of the ambient light, the flashing interval, and the total flashing time. The flashing time in an emergency has a minimum value and cannot be modified.

[0043] When parking and entering sentinel mode, if the left camera 2 or the right camera 5 detects that a person touches the vehicle and stays there for more than the preset time T, which is 30 seconds, the CMS control module 1 controls the left ambient light strip 4 and the right ambient light strip 7 to enter attention mode to remind suspicious persons to stay away.

[0044] The CMS control module 1 communicates with the automobile communication system through the CAN transceiver, and the CMS control module 1 controls the flashing of the ambient light by communicating with the LED control module 8. The LED control module 8 can also communicate directly with the automobile communication system through the CAN transceiver, and the automobile communication system directly controls the left ambient light strip 4 and the right ambient light strip 7. If the communication with the CMS control module 1 can be carried out through the automobile communication system, the robustness is increased.

[0045] At a later stage, information from other sensors, such as millimeter-wave radar and lidar, can be accessed to make more intelligent judgments on dangers, thereby more accurately controlling the flashing of ambient lights and increasing driver comfort.
