Description

Technical Field

[0001] This invention relates to the field of vehicle safety technology, and provides a method, system, and electric vehicle for monitoring vehicles while they are parked. Background Technology

[0002] With economic development and social progress, more and more people are choosing to travel by car. Especially in recent years, with favorable national policies and significant advancements in new energy technologies, new energy vehicles have become mainstream in the automotive industry, and their market share is gradually increasing. More and more people are prioritizing new energy vehicles (pure electric vehicles and hybrid vehicles) when purchasing a car. The cost of new energy vehicles is often higher than that of traditional vehicles, especially high-end models.

[0003] When a vehicle is parked in a parking area, if some parking areas may not have surveillance cameras, there may be blind spots in the surveillance area, or the surveillance cameras may be maliciously damaged, in such cases, if the parked vehicle is damaged and valuables are stolen from the vehicle, or if the damage cannot be verified, the owner of the vehicle shall bear the loss of the vehicle damage and / or theft of the items.

[0004] For the reasons mentioned above, the need for a vehicle self-monitoring system during parking is also urgent. Summary of the Invention

[0005] In view of this, this application provides a vehicle monitoring method during parking, which aims to improve the above-mentioned problems.

[0006] Specifically, the following technical solutions are included:

[0007] On the one hand, the present invention provides a vehicle monitoring method when parking, the method specifically including the following steps:

[0008] S1, Vehicle Parking Monitoring Mode: After the vehicle is powered off, when an object is detected at a first set distance L1 from the vehicle, the camera is activated to collect video from the area around the vehicle.

[0009] S2. Fuse the video captured by the camera with distance information and extract the target object from the video image;

[0010] S3. Detect whether the target object is an abnormal target object, monitor the target object, and issue graded warnings based on the distance of the abnormal target object from the vehicle.

[0011] In some embodiments, the method for identifying abnormal target objects is as follows:

[0012] If the target object stays within a set time T1 within a second set distance L2 from the vehicle, the target object is identified as an abnormal target, wherein the second set distance L2 is less than the first set distance L1.

[0013] In some embodiments, the tiered early warning method is as follows:

[0014] When a target object is determined to be an abnormal target object, a Level 1 warning is issued;

[0015] A level-two warning is issued when an abnormal target remains within a set distance L3 from the vehicle for a set duration T2.

[0016] Among them, the third set distance L3 is less than the second set distance L2.

[0017] In some embodiments, the warning method for a Level 1 warning is as follows: acquire videos within a set time period before and after the warning, store the videos locally while uploading them to a cloud platform, and send the relevant videos to the corresponding user's App through the cloud platform;

[0018] The specific warning method for a Level 2 warning is to control the vehicle lights to flash and / or the horn to sound, so as to attract the attention of people around the vehicle.

[0019] On one hand, the present invention provides a vehicle monitoring system during parking, the system comprising:

[0020] The camera and ultrasonic radar are integrated into the vehicle. The camera and ultrasonic radar are connected to the intelligent driving domain controller. The intelligent driving domain controller is connected to the cockpit domain controller. The cockpit domain controller is connected to the prompting unit.

[0021] In parking monitoring mode, after the vehicle parks, the ultrasonic radar is activated to detect the distance of objects around the vehicle. The ultrasonic radar sends the detected information to the cockpit domain controller through the intelligent driving domain controller. When the cockpit domain controller detects an object at a first set distance L1 from the vehicle, it activates the camera to collect video of the vehicle's surroundings. The video images collected by the camera are fused with the distance information, and the target object in the video image is extracted. The system detects whether the target object is an abnormal target object, monitors the target object, and the alerting unit issues a graded warning based on the distance of the abnormal target object from the vehicle.

[0022] In some embodiments, if a target object stays within a second set distance L2 from the vehicle for a set time T1, the cockpit domain controller identifies the target object as an abnormal target, wherein the second set distance L2 is less than the first set distance L1.

[0023] In some embodiments, when the target object is determined to be an abnormal target object, the prompting unit issues a first-level warning; when the abnormal target stays within a third set distance L3 of the vehicle for a set time T2, the prompting unit issues a second-level warning, where the second set distance L2 is less than the first set distance L1.

[0024] In some embodiments, the alerting unit includes: a mobile terminal, which is wirelessly connected to the cockpit domain controller via a cloud platform; when a Level 1 alert is issued, it sends video footage of the vehicle's surroundings captured by a camera to the vehicle owner's mobile terminal via the cloud platform, and simultaneously stores the video footage of the vehicle's surroundings captured by the camera locally.

[0025] In some embodiments, the prompt unit further includes: vehicle lights and / or a horn;

[0026] When a Level 2 warning is issued, control the vehicle lights to flash and / or sound the horn to attract the attention of people around the vehicle.

[0027] On one hand, the present invention provides an electric vehicle that integrates the aforementioned vehicle monitoring system for parking.

[0028] After the vehicle is powered off, the vehicle monitoring system monitors for abnormal objects around the vehicle while it is parked and issues relevant reminders or warnings in a timely manner to reduce the risk of the vehicle being damaged or stolen. Attached Figure Description

Detailed Implementation

[0033] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0034] Unless otherwise defined, all technical terms used in the embodiments of this application have the same meaning as commonly understood by one of ordinary skill in the art.

[0035] To make the technical solutions and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings. Figure 1 This is a flowchart of a vehicle monitoring method for when a vehicle is parked, provided in an embodiment of the present invention. The method specifically includes the following steps:

[0036] S1, Vehicle Parking Monitoring Mode: After the vehicle is powered off, when an object is detected at a first set distance L1 from the vehicle, the camera is activated to collect video from the area around the vehicle.

[0037] S2. The video images captured by the camera are fused with distance information, and the target objects in the video images are extracted. The target objects include people and vehicles.

[0038] Since the fusion process of the image captured by the camera and the distance information detected by the radar is existing technology, this invention will not elaborate on the fusion process in detail.

[0039] S3. Detect whether the target object is an abnormal target object, monitor the target object, and issue graded warnings based on the distance of the abnormal target object from the vehicle.

[0040] The method for identifying abnormal target objects provided by the present invention is as follows: if a target object stays within a second set distance L2 from the vehicle for a set time T1, the target object is identified as an abnormal target, wherein the second set distance L2 is less than the first set distance L1.

[0041] In this embodiment of the invention, the graded warning method is as follows: when the target object is determined to be an abnormal target object, a first-level warning is issued; when the abnormal target stays within a third set distance L3 of the vehicle for a set time T2, a second-level warning is issued, wherein the third set distance L3 is less than the second set distance L2. The graded warning is based on the distance between the abnormal target object and the vehicle. The closer the distance, the higher the warning level, which is beneficial to ensuring the safety of the vehicle.

[0042] In this embodiment of the invention, the first-level warning method specifically involves: acquiring video footage within a set timeframe before and after the warning, storing the video locally while simultaneously uploading it to a cloud platform, and then sending the relevant video to the corresponding user's app via the cloud platform. It should be noted that before uploading the video to the cloud platform, sensitive information needs to be hidden frame-by-frame in the video to be uploaded. Since vehicles are generally parked in parking lots, the target objects are generally vehicles or people; faces or license plate numbers are hidden through masking or overlay. The second-level warning method specifically involves: controlling the vehicle's lights to flash and / or the horn to sound to attract the attention of people around the vehicle.

[0043] Figure 2 This is a schematic diagram of a vehicle monitoring system for parking provided in an embodiment of the present invention. For ease of explanation, only the parts relevant to the embodiment of the present invention are shown. The system includes:

[0046] In parking monitoring mode, after the vehicle is parked, the ultrasonic radar is activated to detect the distance of objects around the vehicle. The ultrasonic radar sends the detected information to the cockpit domain controller through the intelligent driving domain controller. When the cockpit domain controller detects an object at a first set distance L1 from the vehicle, it activates the camera to capture video around the vehicle. The video images captured by the camera are fused with the distance information, and the target object in the video image is extracted. The system detects whether the target object is an abnormal target object, monitors the target object, and the alerting unit issues a graded warning based on the distance of the abnormal target object from the vehicle.

[0047] In this embodiment of the invention, if the target object stays within a second set distance L2 from the vehicle for a set time T1, the cockpit domain controller identifies the target object as an abnormal target, wherein the second set distance L2 is less than the first set distance L1.

[0048] When the target object is determined to be an abnormal target object, the prompting unit issues a first-level warning; when the abnormal target stays within a third set distance L3 of the vehicle for a set time T2, the prompting unit issues a second-level warning, wherein the third set distance L3 is less than the second set distance L2, and the second set distance L2 is less than the first set distance L1.

[0049] In this embodiment of the invention, the alerting unit includes: a mobile terminal, which is wirelessly connected to the cockpit domain controller via a cloud platform; when a level one alert is issued, the mobile terminal sends video footage of the vehicle's surroundings captured by a camera to the vehicle owner's mobile terminal via the cloud platform, and simultaneously stores the video footage of the vehicle's surroundings captured by the camera locally, saving or sending only the video within a set time period before and after the alert. The mobile terminal can be a mobile phone, tablet, or iPad.

[0050] In this embodiment of the invention, the prompt unit also includes: vehicle lights and / or a horn;

[0051] When a Level 2 warning is issued, control the vehicle lights to flash and / or sound the horn to attract the attention of people around the vehicle.

[0052] In this embodiment of the invention, the system further includes: a central control screen, which is communicatively connected to the cockpit domain controller;

[0053] When the vehicle's parking monitoring mode is activated via the central control screen, the camera and ultrasonic radar will be activated to monitor the vehicle's surroundings after the vehicle is powered off. When the vehicle's monitoring mode is not activated via the central control screen, i.e., the vehicle is in normal mode, the camera and ultrasonic radar will not be activated to monitor the vehicle's surroundings after the vehicle is powered off.

[0054] On the other hand, the present invention also provides an electric vehicle that integrates the above-mentioned vehicle monitoring system when parked. After the vehicle is powered off, the vehicle monitoring system monitors abnormal objects around the vehicle and issues relevant reminders or warnings in a timely manner to reduce the risk of the vehicle being damaged or stolen.
