[0002] Vehicle speed management refers to restricting the speed of a vehicle to prevent speeding, thereby improving driving safety and reducing traffic accidents. Currently, a common method is to equip the vehicle with a car key that includes a speed limiter. By activating the speed limit button on the key, the vehicle speed can be restricted to a relatively safe range. However, this method relies on a physical car key, which is inconvenient for multiple users to share and does not support remote vehicle control, resulting in limited flexibility.

Detailed Implementation Methods

[0020] To better understand the technical solution of this application, the embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0021] It should be understood that the described embodiments are merely some, not all, of the embodiments in this application. All other embodiments obtained by those skilled in the art based on the embodiments in this application without inventive effort are within the scope of protection of this application.

[0022] The terminology used in the embodiments of this application is for the purpose of describing particular embodiments only and is not intended to be limiting of this application. The singular forms “a,” “the,” and “the” used in the embodiments of this application and the appended claims are also intended to include the plural forms unless the context clearly indicates otherwise.

[0023] Figure 1 This is a schematic diagram of a vehicle speed management system provided in an embodiment of this application. Figure 1 As shown, the vehicle speed management system 01 for the above-mentioned vehicle may include: an on-board management device 10, an electronic controller 20 (Electronic Control Unit, ECU), and a communication bus 30.

[0024] The vehicle management device 10, electronic controller 20, and communication bus 30 can be located inside the vehicle. Both the vehicle management device 10 and the electronic controller 20 are connected to the communication bus 30. In one specific implementation, the vehicle management device 10 can be a Telematics Box (T-BOX), and the communication bus 30 can be a Controller Area Network (CAN) bus.

[0025] The vehicle speed management system provided in this application embodiment can be used to perform remote vehicle speed management, and the specific implementation method of performing remote vehicle speed management is as follows.

[0026] In this embodiment of the application, the vehicle may be pre-associated with at least one mobile terminal.

[0027] Taking any mobile terminal as an example: A first application can be configured on the mobile terminal. The first application can be a vehicle speed management application. The user account in the first application can be bound to the vehicle account, thereby establishing a connection between the mobile terminal and the vehicle.

[0028] Based on the aforementioned relationship, the vehicle management device 10 can establish a communication connection with the mobile terminal associated with the vehicle, and thus, the vehicle management device 10 can receive speed limit management commands sent by the mobile terminal. These speed limit management commands may be generated by the speed limit management interface of the first application in response to a speed limit management operation. For example, a speed limit management operation may be a speed limit information input operation performed on the speed limit management interface.

[0029] In one possible implementation, the vehicle management device 10 may include at least one first Bluetooth module, and the mobile terminal associated with the vehicle may include at least one second Bluetooth module. Furthermore, a Bluetooth transmission link can be established between the vehicle management device 10 and the mobile terminal based on the pairing connection of the first and second Bluetooth modules. In this implementation, the vehicle management device 10 can receive speed limit management commands sent by the mobile terminal via Bluetooth communication. When the distance between the vehicle management device 10 and the mobile terminal is short, this implementation can effectively reduce transmission latency and improve communication efficiency.

[0030] Another possible implementation, such as Figure 2 As shown, the vehicle speed management system 01 may further include a cloud server 40. The vehicle management device 10 may include at least one communication module, which can communicate with the cloud server 40. In this implementation, the mobile terminal can establish a communication connection with the cloud server 40 and send speed limit management commands to the cloud server 40. The cloud server 40 can then forward the speed limit management commands to the vehicle management device 10. When the distance between the vehicle management device 10 and the mobile terminal is relatively long, this implementation enables remote communication and effectively improves communication reliability.

[0031] It should be noted that, considering the potential for long-distance communication interruption between the vehicle management device 10 and the mobile terminal in environments with poor communication quality, such as garages, this application embodiment also provides an information transmission method combining long-distance communication and Bluetooth communication. Furthermore, when the long-distance communication signal is strong, the vehicle management device 10 and the mobile terminal can communicate via a cloud server. When the long-distance communication signal weakens, it can switch to Bluetooth communication at any time. This method allows the vehicle's vehicle management device 10 to maintain communication with the mobile terminal even in environments with poor communication quality, such as garages, facilitating the switching of the vehicle's speed mode.

[0032] Furthermore, after receiving the speed limit management command, the vehicle management device 10 can send the speed limit management command to the electronic controller 20 via the communication bus 30.

[0033] Specifically, in this embodiment, it should be noted that the vehicle management device 10 and the electronic controller 20 are connected via a communication bus 30. In real-world scenarios, when the vehicle is not powered on, such as when the vehicle is stationary, in order to reduce the vehicle's power consumption, the battery of some vehicles will default to stopping power supply to the electronic controller 20. Therefore, before sending the speed limit management command to the electronic controller 20, the vehicle management device 10 can first detect the current state of the vehicle.

[0034] If the vehicle is detected to be powered on, the on-board management device 10 can immediately send the speed limit management command to the electronic controller 20 via the communication bus 30.

[0035] If the vehicle is detected to be in a non-powered state, the vehicle management device 10 can store the speed limit management command and continue to monitor the vehicle status until the vehicle is powered on. After that, the vehicle management device 10 can send the speed limit management command to the electronic controller 20 through the communication bus 30.

[0036] Furthermore, after receiving the speed limit management command, the electronic controller 20 can switch the vehicle to speed limit mode according to the speed limit management command.

[0037] It should be noted that after the vehicle is powered on, the electronic controller 20 can receive speed limit management commands sent by the vehicle management device 10 in any state, such as stationary, idling, or driving. Therefore, in this embodiment, to avoid safety accidents caused by sudden deceleration while the vehicle is in motion, the electronic controller 20 can detect whether the vehicle is in motion before performing speed management after receiving the speed limit management command.

[0038] In one possible implementation, the electronic controller 20 detects that the vehicle is in motion. At this time, to ensure driving safety, the electronic controller 20 may temporarily suspend speed management. Once the vehicle is powered on again, the electronic controller 20 can switch the vehicle to speed-limited mode.

[0039] Furthermore, such as Figure 3 As shown in the embodiment of this application, the vehicle speed management system 01 may further include a display instrument 50. The display instrument 50 is located at the front of the vehicle and is connected to the communication bus 30. The display instrument 50 may include a display screen and an instrument control unit. The instrument control unit can control the display screen to display images.

[0040] Based on the aforementioned connection, when it is determined that the vehicle is in motion, the electronic controller 20 can also send a first indication message to the display instrument 50 via the communication bus 30. The first indication message can be used to indicate that a speed limit management command sent by the mobile terminal has been received. Therefore, the instrument control unit of the display instrument 50 can respond to the first indication message and control the display screen to show the corresponding image to the current driver of the vehicle that the vehicle has received a speed limit management command sent by the mobile terminal.

[0041] Correspondingly, the electronic controller 20 can also send feedback information to the mobile terminal. This feedback information can be used to notify the mobile terminal that the vehicle has received the issued speed limit management command. Specifically, the electronic controller 20 can send the feedback information to the on-board management device 10, which then sends the feedback information to the mobile terminal.

[0042] In another possible implementation, the electronic controller 20 detects that the vehicle is not in motion. In this case, the electronic controller 20 can immediately switch the vehicle to a speed-limited mode. "Not in motion" could mean, for example, being in a stopped state after power-on, an idling state, or any other state where the vehicle speed is 0.

[0043] In this embodiment, the electronic controller 20 switches the vehicle to a speed-limited mode by determining the maximum speed specified in the speed-limited mode based on the received speed-limited management command. Then, the electronic controller 20 can control the current vehicle speed based on the proportional-integral-derivative (PID) control method to ensure that the current vehicle speed does not exceed the aforementioned maximum speed.

[0044] Specifically, such as Figure 4 As shown, the vehicle speed management system 01 provided in this embodiment may further include: a vehicle speed sensor 60, a throttle valve body 70, and a fuel injector 80. The electronic controller 20 can use the vehicle speed sensor 60 to obtain the current vehicle speed. Then, the electronic controller 20 can send control signals to the throttle valve body 70 and / or the fuel injector 80 according to the current vehicle speed to control the current vehicle speed to not exceed the aforementioned maximum vehicle speed.

[0045] After switching the vehicle to speed-limited mode, the electronic controller 20 can also send a second instruction message to the display instrument 50 and the vehicle management device 10 via the communication bus. The second instruction message can be used to indicate that the vehicle is in speed-limited mode.

[0046] Upon receiving the first instruction information, the instrument control unit of the display instrument 50 can respond to the second instruction information by controlling the display screen to show the corresponding image to the current driver of the vehicle that the vehicle is currently in speed limit mode.

[0047] After receiving the second instruction information, the vehicle management device 10 can send the second instruction information to a mobile terminal associated with the vehicle. The mobile terminal can then receive and display the second instruction information to show the current user that the vehicle is currently in speed-limited mode.

[0048] It should be noted that, to avoid redundant settings, after the mobile terminal issues the speed management command, the speed management interface of the first application can be locked until the second instruction information is received. In the locked state, the first application cannot respond to speed management operations.

[0049] The above technical solution enables remote vehicle speed management, better ensuring driver safety. Furthermore, this solution allows for vehicle speed management via any mobile terminal, offering greater flexibility and facilitating sharing of vehicle speed management among multiple users, further enhancing convenience.

[0050] In another embodiment of this application, a vehicle may be provided, which may be a motorcycle, an all-terrain vehicle, or the like. The vehicle provided in this application embodiment may include a speed management system for the aforementioned vehicle. Therefore, the vehicle provided in this application embodiment can achieve remote speed management based on the aforementioned speed management system, improving the flexibility and convenience of speed management.
