The information acquisition device comprises four 77GHz millimeter wave radars and a 360-degree panoramic camera, and the millimeter wave radars and the camera are both installed on the top of the vehicle. Firstly, a millimeter wave radar transmits frequency modulation continuous wave signals to the periphery of a vehicle, echoes reflected after the continuous wave signals meet a detection target are received by an antenna, when the transmitted continuous wave signals and the detected target move relatively, the frequency of the echoes is different from that of the transmitted waves, and the movement speed and the distance information of the detection target relative to the radar can be obtained by detecting the frequency difference of the transmitted waves and the echoes. The 360-degree panoramic camera consists of 4 wide-angle cameras and is responsible for collecting image information around the vehicle, the collected information is transmitted to a central processing unit of the vehicle in real time, the central processing unit corrects and splices the collected image information, then performs data fusion with the information collected by the millimeter wave radar, and the three-dimensional driving environment around the vehicle can be obtained after processing and analysis.
The central processing unit is an electronic control unit ECU of the vehicle, and the information acquisition device is connected with the central processing unit through a CAN bus. The electronic control unit ECU is a core component of the control of the automobile, similar to the brain of the automobile. Firstly, the information acquisition device transmits acquired information to the ECU through the CAN bus, then the ECU processes and analyzes the received information to obtain the danger level of the vehicle door opened by the vehicle interior personnel, and when the triggering mechanism detects that the vehicle interior personnel is ready to open the vehicle door, the ECU sends a corresponding execution instruction to the execution device according to the information processing result.
The triggering device includes an infrared sensor 12, and the infrared sensor 12 is installed in a handle groove at the inner side of the vehicle door 10. When a person in the vehicle is ready to pull the door handle to open the door 12, the infrared sensor can detect the action signal and then send a corresponding pulse signal to the central processing unit ECU, the ECU judges the safety of opening the door at the moment according to surrounding driving information, and controls the execution device to finish corresponding pre-warning and collision avoidance actions according to different judged danger levels.
When the system is specifically implemented, the system is started, the information acquisition device starts to acquire driving information around the vehicle, the millimeter wave radar is responsible for acquiring speed and distance information of the surrounding vehicle, the panoramic camera is responsible for acquiring image information around the vehicle, the acquired information is transmitted to an Electronic Control Unit (ECU) of the vehicle in real time through a Controller Area Network (CAN) bus, the ECU corrects and splices the image information acquired by the panoramic camera, then performs data fusion with the information acquired by the millimeter wave radar, and a three-dimensional driving environment around the vehicle CAN be acquired after processing and analysis. The danger level of opening the vehicle door at the moment can be obtained by analyzing the driving information around the vehicle, and when personnel in the vehicle are ready to pull the vehicle door handle to open the vehicle door, the infrared sensor can detect the action signal and then send a corresponding pulse signal to the ECU. When people in the vehicle open the vehicle door without danger, the system has no response, and the vehicle door can be normally opened. When the vehicle door is opened to cause danger, the ECU sends different execution instructions to the execution device according to different danger levels, and finally the execution device completes corresponding early warning and collision avoidance actions.
The risk of opening the door can be divided into two levels: when the danger level is one level, the electronic control unit ECU sends an execution instruction 01 to the execution device, at the moment, a buzzer 13 in the automobile can give out a voice alarm, and an LED warning lamp 11 arranged on the inner side of the automobile door can flash rapidly to remind people in the automobile that the automobile door can be opened at the moment, so that danger exists. When the danger level is the second grade, electronic control unit ECU sends executive instruction 02 to final controlling element, bee calling organ 13 in the car can send voice alarm this moment, install LED warning light 11 on the door and can glimmer rapidly, it can be dangerous to remind personnel in the car to open the door this moment, in addition, the system can send corresponding work order and give electromagnetic lock 3, the output of electromagnetic lock 3 promotes spacing elastomer 5 in the spacing box 7 and slides this moment, spacing elastomer 5 takes place elastic deformation under the 3 squeezing action of electromagnetic lock, make the frictional force increase between spacing arm 6 and the spacing elastomer 5, the mesh that personnel opened the door in the car has been hindered to have been realized.
