Description

Technical Field

[0001] The utility model relates to an electronic rearview mirror integrated with a millimeter wave radar. Background Art

[0002] At present, the commonly used electronic rearview mirror is installed in the car for the driver to observe. It is equipped with a camera on each side to monitor the traffic information on both sides of the car. The image information is transmitted to the controller for processing via the camera. The existing electronic rearview mirror can only observe the information outside the car, and cannot effectively monitor the information inside the car and passengers. The electronic rearview mirror usually only processes the image information provided by the camera, resulting in performance waste. Utility Model Content

[0004] In order to solve the above technical problems, the technical solution of the utility model is:

[0005] An electronic rearview mirror integrated with a millimeter-wave radar, comprising a power module, a first communication module, a second communication module, a CMS control module, and electronic rearview mirror modules arranged on the left and right sides;

[0006] The electronic rearview mirror module includes a camera, a millimeter-wave radar module and a rearview mirror display screen, wherein the camera, the millimeter-wave radar module and the rearview mirror display screen are all connected to a CMS control module, the millimeter-wave radar module is connected to a vehicle body communication system via a first communication module, and the CMS control module is connected to a vehicle body communication system via a second communication module;

[0007] The power module is used to supply power to the millimeter wave radar module and the CMS control module.

[0008] Furthermore, it also includes a main screen, which is connected to the CMS control module.

[0009] Furthermore, the first communication module is a CAN transceiver.

[0010] Furthermore, the second communication module is a CAN transceiver.

[0011] Further, the power supply module includes a first power supply conversion module and a second power supply conversion module;

[0012] The input end of the first power conversion module is connected to the vehicle body BCM, and the output end of the first power conversion module supplies power to the CMS control module;

[0013] The input end of the second power conversion module is connected to the output end of the first power conversion module, and the output end of the second power conversion module supplies power to the millimeter wave radar module.

[0014] Furthermore, the rearview mirror display screen is an LCD display screen.

[0015] By adopting the above technical solution, the utility model provides the driver with real-time and accurate rear traffic information through the electronic rearview mirror modules on the left and right sides, and monitors the heart rate information of passengers in the car through the millimeter wave radar module. When the heart rate information is not within the normal range for a long time, a warning message will be issued on the main screen to remind the driver to avoid accidents. By monitoring the heart rate of passengers in the car through the millimeter wave radar module, it can also be derived to detect whether there are living things forgotten in the main and co-driver seats to avoid the situation where living things are left behind.
