[0020] Optionally, after detecting whether the vehicle is within the electronic fence range, whether the vehicle is in a dangerous road section, and whether the vehicle speed is at a preset speed when the vehicle is powered on again, the process includes:
[0021] If the detection result indicates that the vehicle is within the electronic fence area, or the vehicle is in a dangerous section of road, or the vehicle speed is not the preset speed, then the speed limit instruction will not be executed.
[0022] Secondly, the present invention also provides a vehicle speed limit control device, the vehicle speed limit control device comprising:
[0023] The storage module is used to store the speed limit command when it is received;
[0024] The detection module is used to detect whether the vehicle is within the electronic fence range, whether the vehicle is in a dangerous road section, and whether the vehicle speed is the preset speed when the vehicle is powered on again.
[0025] The speed limit module is used to limit the vehicle speed according to the speed limit command if the detection result shows that the vehicle is not within the electronic fence range, the vehicle is not in a dangerous road section, and the vehicle speed is the preset speed.
[0026] Optionally, the dangerous road sections include highway intersections, crossroads, and tunnels, and the detection module is used for:

[0044] It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
[0045] In a first aspect, embodiments of the present invention provide a vehicle speed limit control device.
[0046] Reference Figure 1 , Figure 1 This is a schematic diagram of the hardware structure of an embodiment of the vehicle speed limit control device of the present invention. In this embodiment, the vehicle speed limit control device may include a processor 1001 (e.g., a Central Processing Unit, CPU), a communication bus 1002, a user interface 1003, a network interface 1004, and a memory 1005. The communication bus 1002 is used to realize communication between these components; the user interface 1003 may include a display screen or an input unit such as a keyboard; the network interface 1004 may optionally include a standard wired interface or a wireless interface (e.g., Wireless Fidelity, Wi-Fi); the memory 1005 may be high-speed random access memory (RAM) or stable memory (non-volatile memory), such as a disk storage device. Alternatively, the memory 1005 may also be a storage device independent of the aforementioned processor 1001. Those skilled in the art will understand that… Figure 1 The hardware structure shown does not constitute a limitation of the invention and may include more or fewer components than shown, or combine certain components, or have different component arrangements.
[0047] Continue to refer to Figure 1 , Figure 1The memory 1005, which serves as a computer storage medium, may include an operating system, a network communication module, a user interface module, and a vehicle speed limit control program. The processor 1001 can call the vehicle speed limit control program stored in the memory 1005 and execute the vehicle speed limit control method provided in this embodiment of the invention.
[0048] Secondly, embodiments of the present invention provide a vehicle speed limit control method.
[0049] To more clearly demonstrate the vehicle speed limit control method provided in the embodiments of this application, we will first introduce the application scenarios of the vehicle speed limit control method provided in the embodiments of this application.
[0050] The vehicle speed limit control method provided in this application embodiment is applied in scenarios such as when a vehicle is stolen or other situations where the vehicle speed needs to be limited. The user sends a speed limit command to the vehicle through a remote application to limit the vehicle speed. Since limiting the vehicle speed may cause the vehicle speed to drop suddenly, which may easily cause safety hazards, it is necessary to fully consider and protect the safety of the vehicle and its occupants.
[0051] In one embodiment, reference is made to Figure 2 , Figure 2 This is a flowchart illustrating an embodiment of the vehicle speed limit control method of the present invention, as shown below. Figure 2 As shown, the vehicle speed limit control method includes:
[0052] Step S10: When a speed limit instruction is received, the speed limit instruction is stored.
[0053] In this embodiment, for example, when a vehicle is stolen or in other scenarios where the vehicle speed needs to be limited, the user sends a speed limit command to the vehicle via a remote application. The speed limit command means to control the vehicle speed to a certain value or below, which includes 0. When the vehicle's terminal device receives the speed limit command, if the speed limit command is executed immediately, the vehicle speed may drop sharply, which may cause safety hazards. Therefore, in order to ensure the safety of the vehicle and its occupants, the speed limit command is not executed immediately, but is stored first.
[0054] Step S20: When the vehicle is powered on again, detect whether the vehicle is within the electronic fence range, whether the vehicle is in a dangerous road section, and whether the vehicle speed is the preset speed.
[0055] In this embodiment, if the vehicle is in the middle of a journey, one journey is one driving process from power-on to power-off. No speed limit will be implemented. Instead, when the vehicle is powered on again, the relevant safety conditions will be checked to determine whether to implement the speed limit.
[0056] Step S30: If the detection result is that the vehicle is not within the electronic fence range, the vehicle is not in a dangerous road section, and the vehicle speed is the preset speed, then the vehicle speed is limited according to the speed limit instruction.
[0057] In this embodiment, the electronic fence is a manually defined area where vehicles can safely travel. When a vehicle is traveling within this area, its safety is considered high, and no speed limit is required. When a vehicle travels outside this area, it is considered that there may be a risk of theft, and a speed limit is required. Dangerous road sections include, but are not limited to, highway intersections, crossroads, and tunnels. If vehicle speed is limited on such dangerous road sections, it may cause traffic congestion or even traffic accidents. Limiting vehicle speed when it is at a preset speed, such as 0, is relatively safe. When all three safety conditions mentioned above are met... When the conditions are met, the vehicle speed is limited according to the speed limit command, thereby improving the safety of the vehicle and its occupants. Limiting the vehicle speed means controlling the vehicle speed to a certain value or below, limiting the engine speed to a certain value or below, or limiting the vehicle's output torque to a certain value or below. The certain value includes 0, which is equivalent to stopping the vehicle. If the above three safety conditions are not met simultaneously, the speed limit will not be executed. The system continuously checks whether the above three conditions are met simultaneously. When the above three conditions are met simultaneously, the vehicle speed is limited according to the speed limit command.
[0058] In this embodiment, for example, when a vehicle is stolen or in other scenarios where vehicle speed needs to be limited, the user sends a speed limit command to the vehicle via a remote application. The vehicle's terminal device receives the speed limit command. When the speed limit command is received, to ensure the safety of the vehicle and its occupants, the speed limit is not executed immediately. Instead, the speed limit command is stored first. Then, when the vehicle is powered on again, a check is performed. If the conditions are met simultaneously that the vehicle is not within the electronic fence range, is not in a dangerous road section, and the vehicle speed is a preset speed, such as 0, then the vehicle speed is limited. This can improve the safety of the vehicle and its occupants when limiting the vehicle speed.
[0059] Furthermore, in one embodiment, reference is made to Figure 3 , Figure 3 for Figure 2 A detailed flowchart of step S20 is shown below. Figure 3 As shown, the dangerous road sections include highway intersections, crossroads, and tunnels. Step S20 includes:
[0060] Step S201: Acquire road images using the vehicle-mounted camera;
[0061] Step S202: Perform image recognition on the acquired road image;
[0062] Step S203: If the image recognition result is a highway intersection, crossroads, or tunnel, the detection result is that the vehicle is in a dangerous road section; otherwise, the detection result is that the vehicle is not in a dangerous road section.
[0063] In this embodiment, dangerous road sections include, but are not limited to, highway intersections, crossroads, and tunnels. Any road section that may cause traffic safety hazards when speed limits are enforced can be classified as a dangerous road section. After acquiring road images through the vehicle-mounted camera, a machine vision algorithm is used to compare the acquired road images with preset images of highway intersections, crossroads, and tunnels. If the road image matches one of the preset images of highway intersections, crossroads, and tunnels, the detection result is that the vehicle is in a dangerous road section; otherwise, the detection result is that the vehicle is not in a dangerous road section.
[0064] Furthermore, in one embodiment, reference is made to Figure 4 , Figure 4 for Figure 2 Another detailed flowchart of step S20 is shown below. Figure 4 As shown, step S20 further includes:
[0065] Step S204: Obtain road information from the roadside unit;
[0066] Step S205: Determine whether the vehicle is located at a highway intersection, crossroads, or tunnel based on the obtained road information;
[0067] Step S206: If yes, the detection result is that the vehicle is in a dangerous road section; otherwise, the detection result is that the vehicle is not in a dangerous road section.
[0068] In this embodiment, the Roadside Unit (RSU) is an important component of the vehicle-road cooperative roadside terminal. Its main function is to collect information such as current road conditions and traffic conditions, and communicate with roadside sensing devices, traffic lights, electronic signs and other terminals through the communication network to realize vehicle-road interconnection and real-time traffic signal interaction, assist drivers in driving, and ensure the safety of personnel and vehicles in the entire traffic field. Through vehicle-side devices such as T-BOX (Telematic-BOX, intelligent vehicle terminal) to obtain road information from the Roadside Unit, it determines whether the vehicle is located at one of the following road conditions: highway intersection, crossroads and tunnel. If so, the detection result is that the vehicle is in a dangerous road section; otherwise, the detection result is that the vehicle is not in a dangerous road section.
[0069] Furthermore, in one embodiment, reference is made to Figure 5 , Figure 5 for Figure 2 A detailed flowchart of step S10 is provided. Step S10 includes:
[0070] Step S101: When a speed limit command is received, check whether the vehicle is powered on.
[0071] Step S102: If yes, output a speed limit reminder and store the speed limit command;
[0072] Step S103: If not, store the vehicle speed limit instruction.
[0073] In this embodiment, upon receiving a speed limit command, the system checks whether the vehicle is powered on. Regardless of whether the vehicle is powered on, the speed limit command is stored for future speed limits. When the vehicle is powered on, the system further alerts the driver and passengers through instruments, sound and light, etc., that a speed limit is about to be implemented. After receiving the speed limit alert, the driver and passengers can take certain measures to improve their safety, such as driving away from dangerous road sections or reducing vehicle speed, to avoid dangerous situations.
[0074] Further, in one embodiment, after step S20, the following is included:
[0075] If the detection result indicates that the vehicle is within the electronic fence area, or the vehicle is in a dangerous section of road, or the vehicle speed is not the preset speed, then the speed limit instruction will not be executed.
[0076] In this embodiment, when a vehicle is within the electronic fence range, there is no need to limit the vehicle speed. When the vehicle is in a dangerous road section, such as a highway intersection, crossroads, or tunnel, there is no speed limit. If a speed limit is imposed on such road sections, it can easily lead to traffic congestion or even traffic accidents. When the vehicle speed is not the preset speed, such as when the preset speed is 0, if a speed limit is imposed, the sudden decrease in speed may pose a safety hazard. Therefore, when the vehicle speed is not the preset speed, such as when the preset speed is 0, there is no speed limit.
[0077] Furthermore, in one embodiment, the dangerous road section includes highway intersections, crossroads, and tunnels, and step S20 includes:
[0078] Step S201: Acquire road images using the vehicle-mounted camera;
[0079] Step S202: Perform image recognition on the acquired road image;
[0080] Step S203: If the image recognition result is a highway intersection, crossroads, or tunnel, the detection result is that the vehicle is in a dangerous road section; otherwise, the detection result is that the vehicle is not in a dangerous road section.
[0081] Step S204: Obtain road information from the roadside unit;
[0082] Step S205: Determine whether the vehicle is located at a highway intersection, crossroads, or tunnel based on the obtained road information;
[0083] Step S206: If yes, the detection result is that the vehicle is in a dangerous road section; otherwise, the detection result is that the vehicle is not in a dangerous road section.
[0084] In this embodiment, dangerous road sections include, but are not limited to, highway intersections, crossroads, and tunnels. Any road section that might pose a safety hazard to traffic if speed limits are enforced can be classified as a dangerous road section. Two methods are used to detect whether a vehicle is in a dangerous road section. Method one: After acquiring road images using an onboard camera, a machine vision algorithm is used to compare the acquired road images with preset images of highway intersections, crossroads, and tunnels. If the road image matches any one of the preset images, the detection result is determined to be that the vehicle is in a dangerous road section; otherwise, the detection result is... To ensure the vehicle is not in a dangerous road section, Method Two involves using vehicle-mounted devices such as T-BOX (Telematic-BOX, intelligent vehicle terminal) to obtain road information from roadside units. Based on the obtained road information, it is determined whether the vehicle is located at one of the following road conditions: highway intersection, crossroads, or tunnel. If so, the detection result is that the vehicle is in a dangerous road section; otherwise, the detection result is that the vehicle is not in a dangerous road section. If the vehicle is detected as being in a dangerous road section by one of these methods, it is determined that the vehicle is in a dangerous road section. Only if both methods detect that the vehicle is not in a dangerous road section is it determined that the vehicle is not in a dangerous road section.
[0085] Thirdly, embodiments of the present invention also provide a vehicle speed limit control device.
[0086] Reference Figure 6 , Figure 6 This is a schematic diagram of the functional modules of an embodiment of the vehicle speed limit control device of the present invention.
[0087] In this embodiment, the vehicle speed limit control device includes:
[0088] The storage module 10 is used to store the speed limit instruction when it is received.
[0089] In this embodiment, for example, when a vehicle is stolen or in other scenarios where the vehicle speed needs to be limited, the user sends a speed limit command to the vehicle via a remote application. The speed limit command means to control the vehicle speed to a certain value or below, which includes 0. When the vehicle's terminal device receives the speed limit command, if the speed limit command is executed immediately, the vehicle speed may drop sharply, which may cause safety hazards. Therefore, in order to ensure the safety of the vehicle and its occupants, the speed limit command is not executed immediately, but is stored first.
[0090] The detection module 20 is used to detect whether the vehicle is within the electronic fence range, whether the vehicle is in a dangerous road section, and whether the vehicle speed is the preset speed when the vehicle is powered on again.
[0091] In this embodiment, if the vehicle is in the middle of a journey, one journey is one driving process from power-on to power-off. No speed limit will be implemented. Instead, when the vehicle is powered on again, the relevant safety conditions will be checked to determine whether to implement the speed limit.
[0092] The limiting module 30 is used to limit the vehicle speed according to the speed limit command if the detection result is that the vehicle is not within the range of the electronic fence, the vehicle is not in a dangerous road section, and the vehicle speed is the preset speed.
[0093] In this embodiment, the electronic fence is a manually defined area where vehicles can safely travel. When a vehicle travels within this area, its safety is considered high, and there is no need to limit its speed. When a vehicle travels outside this area, it is considered that there may be risks such as theft, and its speed needs to be limited. Dangerous road sections include, but are not limited to, highway intersections, crossroads, and tunnels. If vehicle speed is limited on such dangerous road sections, it may cause traffic congestion or even traffic accidents. Limiting the vehicle speed when it is at a preset speed, such as 0, is relatively safe. When all three safety conditions are met, the vehicle speed is limited according to the speed limit command, thereby improving the safety of the vehicle and its occupants. Limiting the vehicle speed means controlling the vehicle speed to a certain value or below, or limiting the engine speed to a certain value or below, or limiting the vehicle's output torque to a certain value or below. The certain value includes 0, which is equivalent to stopping the vehicle.
[0094] Furthermore, in one embodiment, the dangerous road section includes highway intersections, crossroads, and tunnels, and the detection module 20 is used for:
[0095] Obtain road images using vehicle-mounted cameras;
[0096] Perform image recognition on the acquired road images;
[0097] If the image recognition result indicates a highway intersection, crossroads, or tunnel, the detection result is that the vehicle is in a dangerous road section; otherwise, the detection result is that the vehicle is not in a dangerous road section.
[0098] In this embodiment, dangerous road sections include, but are not limited to, highway intersections, crossroads, and tunnels. Any road section that may cause traffic safety hazards when speed limits are enforced can be classified as a dangerous road section. After acquiring road images through the vehicle-mounted camera, a machine vision algorithm is used to compare the acquired road images with preset images of highway intersections, crossroads, and tunnels. If the road image matches one of the preset images of highway intersections, crossroads, and tunnels, the detection result is that the vehicle is in a dangerous road section; otherwise, the detection result is that the vehicle is not in a dangerous road section.
[0099] Furthermore, in one embodiment, the detection module 20 is also used for:
[0100] Obtain road information from roadside units;
[0101] Determine whether the vehicle is located at a highway entrance, intersection, or tunnel based on the obtained road information;
[0102] If so, the detection result is that the vehicle is in a dangerous road section; otherwise, the detection result is that the vehicle is not in a dangerous road section.
[0103] In this embodiment, the Roadside Unit (RSU) is an important component of the vehicle-road cooperative roadside terminal. Its main function is to collect information such as current road conditions and traffic conditions, and communicate with roadside sensing devices, traffic lights, electronic signs and other terminals through the communication network to realize vehicle-road interconnection and real-time traffic signal interaction, assist drivers in driving, and ensure the safety of personnel and vehicles in the entire traffic field. Through vehicle-side devices such as T-BOX (Telematic-BOX, intelligent vehicle terminal) to obtain road information from the Roadside Unit, it determines whether the vehicle is located at one of the following road conditions: highway intersection, crossroads and tunnel. If so, the detection result is that the vehicle is in a dangerous road section; otherwise, the detection result is that the vehicle is not in a dangerous road section.
[0104] Furthermore, in one embodiment, the storage module 10 is used for:
[0105] When a speed limit command is received, check whether the vehicle is powered on.
[0106] If so, output a speed limit reminder and store the speed limit command;
[0107] If not, store the vehicle speed limit instruction.
[0108] In this embodiment, upon receiving a speed limit command, the system checks whether the vehicle is powered on. Regardless of whether the vehicle is powered on, the speed limit command is stored for future speed limits. When the vehicle is powered on, the system further alerts the driver and passengers through instruments, sound and light, etc., that a speed limit is about to be implemented. After receiving the speed limit alert, the driver and passengers can take certain measures to improve their safety, such as driving away from dangerous road sections or reducing vehicle speed, to avoid dangerous situations.
[0109] Furthermore, in one embodiment, the vehicle speed limit control device further includes an execution module for:
[0110] If the detection result indicates that the vehicle is within the electronic fence area, or the vehicle is in a dangerous section of road, or the vehicle speed is not the preset speed, then the speed limit instruction will not be executed.
[0111] In this embodiment, when a vehicle is within the electronic fence range, there is no need to limit the vehicle speed. When the vehicle is in a dangerous road section, such as a highway intersection, crossroads, or tunnel, there is no speed limit. If a speed limit is imposed on such road sections, it can easily lead to traffic congestion or even traffic accidents. When the vehicle speed is not the preset speed, such as when the preset speed is 0, if a speed limit is imposed, the sudden decrease in speed may pose a safety hazard. Therefore, when the vehicle speed is not the preset speed, such as when the preset speed is 0, there is no speed limit.
[0112] Fourthly, embodiments of the present invention also provide a readable storage medium.
[0113] The present invention provides a readable storage medium storing a vehicle speed limit control program, wherein when the vehicle speed limit control program is executed by a processor, it implements the steps of the vehicle speed limit control method described above.
