Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of vehicle monitoring, and in particular to a vehicle door and window status monitoring and early warning method and system. Background Art
[0002] The statements in this section merely mention background art related to the present invention and do not necessarily constitute prior art.
[0003] With the development of intelligent vehicles, vehicle safety systems are receiving increasing attention. However, the power windows of some models are inoperable after the engine is turned off. If the driver inadvertently leaves the windows open, traditional vehicle locking systems only ensure the doors are locked but cannot detect whether the doors or windows are fully closed, potentially leading to theft of property or rainwater infiltration.
[0004] When a vehicle detects a door or window is not closed, it primarily alerts the owner through the following methods: First, a buzzer alarm sounds when an anomaly is detected after the key is left in the vehicle or the ignition is turned off, but this can be easily overlooked in noisy environments. Second, a dashboard icon displays a red warning icon or text, requiring the driver to actively check the instrument panel and providing poor visibility at night. These solutions rely on the user's presence, passive interaction, and poor environmental adaptability, resulting in significant limitations. They are unable to continuously monitor status changes (such as a window being pried open) after the vehicle is locked and promptly notify the owner. Summary of the Invention

DETAILED DESCRIPTION
[0020] It should be noted that the following detailed descriptions are exemplary and intended to provide further explanation of the present invention. Unless otherwise specified, all technical and scientific terms used in the present invention have the same meanings as those commonly understood by those skilled in the art to which the present invention belongs.
[0021] It should be noted that the terms used herein are only for describing specific embodiments and are not intended to limit exemplary embodiments according to the present invention. As used herein, unless the context clearly indicates otherwise, the singular form is also intended to include the plural form. In addition, it should be understood that the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions. For example, a process, method, system, product or device comprising a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.
[0022] In the absence of conflict, the embodiments of the present invention and the features thereof may be combined with each other.
[0023] Example 1 The interaction efficiency between the existing vehicle door and window switch status monitoring and warning and the vehicle owner is low, and the warning effect needs to be improved; therefore, the present application provides a vehicle door and window status monitoring and warning method, which uses different warning methods to provide graded warnings when there are open doors and windows and the vehicle owner intends to lock the doors, taking into account the parking environment, parking time and weather.
[0024] Next, combine Figure 1 , a vehicle door and window status monitoring and early warning method disclosed in this embodiment is described in detail. The vehicle door and window status monitoring and early warning method is deployed on a cloud server and includes the following steps: Step 1: Get the vehicle's door and window status information. If the door and window status information indicates that the vehicle's doors and windows are not closed and the vehicle lock signal is received, proceed to step 2.
[0025] In this embodiment, the door and window status information is collected in response to the driver's departure signal through the Hall sensor and pressure sensor integrated inside the vehicle. When the door and window status information is abnormal, the door and window status information is transmitted to the cloud server through the vehicle network communication module. Among them, the pressure sensor determines whether the doors and windows are completely closed by obtaining the pressure at the doors and windows.
[0026] When the Hall sensor detects a change in the magnetic field, it will output a corresponding electrical signal, which is used to determine whether the doors and windows are open and the degree to which they are open.
[0027] For example, the status of each window collected by the sensor can be expressed as: 0x00-fully closed, 0x01-not closed, 0x02-not fully closed (closing degree <98%), generating a CAN data frame (ID 0x201, data bit 0x0F indicates that the four windows are not closed); the door status: 0x00-fully closed, 0x01-not closed, generating a CAN data frame (ID 0x202, data bit 0x0F indicates that the four doors are not closed).
[0028] Here, when it is detected that the vehicle is stalled, the current gear of the vehicle is P gear, the duration of P gear is greater than the preset time threshold, and the weight monitored by the pressure sensor on the driver's seat is less than the set weight threshold, a driver departure signal is generated; after the driver departure signal is generated, the monitoring of the vehicle door and window status is triggered.
[0029] Here, the time threshold may be 10 minutes, and the weight threshold is usually set to 15 kg.
[0030] Furthermore, in order to continue to monitor the status of vehicle doors and windows when the sensor is malfunctioning, in the vehicle terminal, in response to the sensor abnormality signal, the collected interior environment image is processed by a lightweight target detection model to generate the vehicle's door and window status information. The interior environment image is collected by the in-vehicle camera.
[0031] In this embodiment, the lightweight target detection model can be a trained yolov8 model, the input is the interior environment image, and the output is the door and window status information of the vehicle; the yolov8 model is trained by constructing a training set by a large number of interior environment images marked with door and window status information until the preset number of training times is reached.
[0032] Step 2: Push warning information to the car owner's mobile phone APP terminal based on the door and window monitoring graded warning strategy; specifically including: S101. Classify the parking environment of the vehicle and determine the environmental risk index.
[0033] Furthermore, the address information of the vehicle is determined, the parking environment is determined based on the address information, and the environmental risk index is determined according to the screening result of the parking environment in a preset parking environment classification table.
[0034] In this embodiment, the vehicle's address information can be determined through GPS and / or Bluetooth technology, and the parking environment can be determined based on keywords in the address information; the parking environment classification table is shown in the following table.
[0035]
[0036] S102: Obtain the historical behavior data of the vehicle owner and perform behavior modeling to determine the parking time level; and determine the parking time risk index based on the screening result of the parking time level in the preset parking time classification table.
[0037] In this embodiment, the trained LSTM network is used to process the historical behavior data of the car owner to obtain the parking time grade. The parking time grade table is as follows:
[0038] S103: Acquire weather information, and determine a weather risk index based on a screening result of the weather information in a preset weather condition classification table.
[0039] In this embodiment, the weather condition classification table is as follows:
[0040] S104. Determine a comprehensive risk value based on the environmental risk index, the duration risk index, and the weather risk index; determine a warning level based on the comprehensive risk value, and push warning information to the user end in a corresponding warning form.
[0041] For example, the comprehensive risk value R is expressed as: R = α × (A × environmental risk index + B × weather risk index + C × duration risk index); Where α is the security level coefficient of the parking area, A, B, and C are weight coefficients, and their specific values can be the corresponding risk index / 100.
[0042] Public security level coefficient The determination process includes: Get the camera density of the parking area and the maximum camera density in the city where the parking area is located ; The public security level coefficient is calculated based on the camera density of the parking area and the maximum camera density of the city where the parking area is located. The calculation formula for the public security level coefficient is:
[0043] Among them, the density of parking area cameras is obtained through the urban grid management platform and the maximum camera density in the city where the parking area is located .
[0044] Furthermore, if the comprehensive risk value is not greater than the preset first threshold, the warning level is Level I, and the corresponding warning form is pushing a warning message within the APP; if the comprehensive risk value is greater than the preset first threshold and less than or equal to the preset second threshold, the warning level is Level II, and the corresponding warning form is SMS push; if the comprehensive risk value is greater than the preset second threshold and less than or equal to the preset third threshold, the warning level is Level III, and the corresponding warning form is pushing a voice warning message through the user's phone within the APP; if the comprehensive risk value is greater than the preset third threshold, the warning level is Level IV, and the corresponding warning form is expedited pushing of a voice warning message through the user's phone and the reserved phone within the APP.
[0045] For example, the warning level determination criteria and their corresponding warning forms are shown in the following table:
[0046] Phone trigger: After the APP receives the alarm, it calls the car owner's phone number bound to the APP through the system phone API; Voice notification: The ALM language model is used for intelligent analysis to generate personalized voice prompts. Prompts are generated based on current weather conditions, time period, and area (shopping mall, outdoor), and then played as an intelligent voice reminder after the call is connected. For example, if the car windows are not closed and it is about to rain, it will remind the driver, "The probability of rain is expected to be 80% in 1 hour. Do you need to close the windows?" User interaction: After the voice message ends, the APP interface displays the "Remote Shutdown" button (requires vehicle support) and the "I Have Processed" option.
[0047] Furthermore, after the user receives the warning, he clicks "remote close" through the APP. The APP sends a remote close command to the cloud. The on-board communication module triggers the body control module to close the doors and windows through the CAN bus. The remote close command: CAN ID: 0x301, data: 0x01 (close all doors and windows), 0x02 (close specified doors and windows).
[0048] The Body Control Module (BCM) is an electronic control unit (ECU) that manages vehicle functions such as lighting, windows, door locks, and seat controls.
[0049] After the body control module performs the closing operation, it re-checks the status of the doors and windows and uploads the latest status information to the cloud to ensure that the app interface is updated with the latest status. Finally, the monitoring and warning process ends and the system waits for the next lock command to be triggered.
[0050] Example 2 This embodiment discloses a vehicle door and window status monitoring and warning system, including a door and window status detection module, a vehicle network communication module, and a cloud server. The door and window status detection module is deployed on a vehicle terminal to monitor the vehicle's door and window status information. The vehicle network communication module is used to transmit the door and window status information to the cloud server. The cloud server is used to obtain the vehicle's door and window status information. If the door and window status information indicates that the door and window are not closed and a vehicle lock signal is received, a door and window monitoring graded warning strategy is executed. The door and window monitoring graded warning strategy includes: The parking environment of the vehicle is graded to determine the environmental risk index; the historical behavior data of the vehicle owner is obtained and behavioral modeling is performed to determine the parking time level; based on the screening results of the parking time level in the preset parking time classification table, the time risk index is determined; weather information is obtained, and based on the screening results of the weather information in the preset weather condition classification table, the weather risk index is determined; based on the environmental risk index, the time risk index and the weather risk index, the comprehensive risk value is determined; based on the comprehensive risk value, the warning level is determined and the warning information is pushed to the user end in the corresponding warning form.
[0051] Furthermore, the door and window status detection module deploys a lightweight object detection model. This model uses in-vehicle cameras to monitor the door and window status, as well as the interior environment, in real time. Furthermore, physical sensors integrated into the vehicle, such as Hall sensors and pressure sensors, collect real-time information on the status of each door and window. This serves as a redundant check, improving the reliability of the multimodal sensor fusion solution. If a door or window is detected as partially closed, the detection module sends an abnormality signal to the connected vehicle communication module.
[0052] The Internet of Vehicles communication module receives abnormal signals sent by the sensor module, converts them into data packets, and transmits them to the cloud server through the mobile communication network; at the same time, the module is also responsible for receiving instructions or data sent by the cloud server, such as remote locking and unlocking of the vehicle.
[0053] The cloud server is responsible for parsing the data uploaded by the Internet of Vehicles communication module, and making a final graded judgment based on various information such as abnormal door and window status and vehicle parking environment, to determine the driver's intention, whether the vehicle is temporarily locked, etc., and generate an alarm event and push it to the APP; at the same time, it receives remote control commands sent by the APP and forwards them to the Internet of Vehicles communication module for execution.
[0054] The smart mobile terminal app, installed on the owner's smartphone, receives information about the vehicle's doors and windows from a cloud server. It provides one-touch emergency phone alerts and remote control capabilities. When the app receives abnormal status information, it automatically triggers a phone call and plays a voice alert, immediately sending a warning notification to the owner. A "remote close" button is also provided for remote control of the vehicle's doors and windows. The app also offers features such as vehicle status query and history review.
