[0023] The specific implementation of the present invention is further described in detail below in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0024] like Figure 1-10 As shown, the utility model provides a logo light control system with integrated millimeter wave radar, the logo light 10 is arranged in the middle of the trunk lid 6 of the vehicle, the logo light 10 includes a light board 11 and a lamp cover 12 covered on the light board 11, the light board 11 includes: a radar sensing module 1, an MCU module 2, a driving circuit 3 and a lamp bead 4, the radar sensing module 1 is electrically connected to the MCU module 2, the MCU module 2 is electrically connected to the communication system 5 of the vehicle, and the MCU module 2 is electrically connected to the lamp bead 4 through the driving circuit 3. The utility model sets the radar sensing module 1 in the logo light 10, and the vehicle can automatically light up or turn off the logo light 10 through intelligent sensing.

[0025] The model of the MCU module 2 of the present utility model is FS32K144HAT0MLHT. Figure 7 As shown in FIG8 , the power management chip of the utility model supplies power to the radar sensing module 1. The power management chip converts the 12V power provided by the automobile power supply system into a 3.3V voltage for use by the radar sensing module 1. The model of the power management chip used is LP87524JRNFRQ1, as shown in FIG8 . The model of the radar sensing module 1 of the utility model is AWR6843ARBGALPQ1. The circuit schematic diagram of the LDO module, LED drive circuit, and LED lamp group of the utility model is shown in FIG8 Fig. 9 As shown, the radar sensing module 1 of the utility model is connected to the automobile communication system through the first communication module, and the MCU module 2 is connected to the automobile communication system through the second communication module, so that the radar sensing module 1 and the MCU module 2 communicate with each other. The first communication module of the utility model is the CAN transceiver U12, and the second communication module is the CAN transceiver U17. Fig.10 shown.

[0026] The communication system 5 is electrically connected to the trunk lid 6, the radar sensing module 1 detects the foot swing signal and transmits the signal to the MCU module 2, the MCU module 2 transmits the signal to the communication system 5, and the communication system 5 transmits the signal to open the trunk lid 6. The logo light 10 is combined with the trunk lid 6, and the logo light 10 detects a specific action to open the trunk, solving the problem of inconvenience in opening the trunk when using both hands.

[0027] The Logo light control system with integrated millimeter-wave radar includes a vehicle key module 7, which is electrically connected to a communication system 5. When the vehicle key module 7 is within the sensing range of the vehicle, the radar sensing module 1 detects the movement of the object and generates a command to send to the MCU module 2, which controls the lighting of the Logo light 10. When the user approaches the sensing range of the vehicle with the key, the key sends a signal, and after the vehicle receives the signal and matches successfully, the vehicle is activated, the communication system 5 enters the standby state, and the radar sensing module 1 of the Logo light 10 enters the scanning state. If a moving object is detected, such as a person approaching or passing by, the Logo light will automatically light up.

[0028] When the vehicle is in a driving state, the radar sensing module 1 is turned off. When the vehicle is in a parking state, the radar sensing module 1 is turned on.

[0029] The radar sensing module 1 detects the hand-waving signal and transmits the signal to the MCU module 2, which transmits the signal to the communication system 5, which transmits the signal to turn off the Logo light 10. If you want to open the trunk, you can use action 1 under the rear of the car: swing your feet left and right. After 2-3 rounds, the radar sensing module 1 is a millimeter-wave radar. After collecting the trunk opening signal, it is transmitted to the MCU module 2. The MCU module 2 transmits it to the car's communication system 5 through the CAN transceiver. The car communication system 5 sends an opening signal to the switch of the trunk lid 6, and then the trunk lid 6 is opened. When the trunk lid 6 is in the open state, the radar sensing module 1 enters the standby state. After the trunk lid 6 is closed, it sends a signal to the car communication system 5. The car communication system 5 sends information to the MCU module 2, and the MCU module 2 activates the radar sensing module 1 to put it in the scanning state. When the vehicle is in the driving state, the radar sensing module 1 is turned off, and when it is in the parking state, the radar sensing module 1 is normally turned on. If you want to turn off the Logo light 10, you can stand behind the rear of the car and take action 2: waving your hand. After 2-3 rounds, the radar system module will collect the light-off command and send a signal to the MCU module 2. The MCU module 2 controls the drive circuit 3 to turn off the lamp bead 4. If you want to light up the Logo light 10 again, you can repeat action 2: waving your hand. After the radar sensing module 1 collects the light-on command, it will pass the signal to the MCU module 2. The MCU module 2 controls the drive circuit 3 to light up the Logo light 10.

[0030] The lamp cover 12 isolates the lamp board 11 from the outside world, and is waterproof and dustproof. The beam signal emitted by the millimeter-wave radar can pass through the lamp cover. After contacting an object, the echo signal can be sensed by the millimeter-wave radar through the lamp cover 12 for analysis.

[0031] The logo light 10 can subsequently define its own actions to determine whether the logo light 10 turns on or off and whether the trunk lid 6 is opened.

[0032] In summary, the Logo light control system of the utility model with integrated millimeter-wave radar, in addition to being manually lit, can also automatically light up the Logo light when it senses the person holding the key around the vehicle, and in addition to being turned off manually, the Logo light can also be turned off through specific actions. Not only that, the Logo light is combined with the trunk, and the Logo light detects specific actions to open the trunk, solving the problem of the inconvenience of opening the trunk when using both hands.
