Description

Technical Field

[0001] This application relates to the field of vehicle technology, and more specifically, to a method, system, terminal, and vehicle for remote control of a brake air pump. Background Technology

[0002] For commercial heavy-duty vehicles, the brake air pump's inflation function has a prerequisite: starting the power system. For example, fuel-powered vehicles require starting the engine, and pure electric vehicles require connecting the high-voltage power battery. When the vehicle is equipped with remote-controlled air conditioning or remote charging functions, it also supports remote triggering to enter the above prerequisite state.

[0003] Remote air conditioning control and remote power replenishment functions both have remote start capabilities, such as starting the engine or powering the vehicle's high voltage. However, both remote air conditioning and remote power replenishment functions typically have short operating cycles. Once the corresponding remote function is deactivated, the engine or vehicle's high-voltage system will stop operating, and the brake pump will stop inflating. This results in insufficient inflation time for the brake pump, potentially causing the brake air pressure to fall below the standard required for normal driving. Consequently, the user will need to manually inflate the brake pump after getting into the vehicle, reducing its convenience. Summary of the Invention

[0004] The purpose of this application is to address the shortcomings of the prior art by providing a method, system, terminal, and vehicle for remote control of a brake air pump, thereby enabling remote air replenishment of the brake air pump and improving the ease of use of the vehicle.

[0005] To achieve the above objectives, the technical solutions adopted in the embodiments of the present invention are as follows: In a first aspect, embodiments of the present invention provide a remote control method for a brake air pump, applied to an in-vehicle terminal, the method comprising: Receive remote inflation commands sent by the application client through the monitoring platform; Determine whether the current vehicle status of the heavy vehicle meets the preset remote start conditions of the power system; If the preset remote start conditions are met, a start command is sent to the power system, causing the power system to enter the start state, and the brake air pump automatically enters the air pumping state until the air pumping is completed. Receive the brake air pressure status after the brake pump has finished inflating; Send a shutdown command to the power system, causing the power system to enter a shutdown state; The brake pressure status after inflation and the result of this remote inflation execution are sent to the monitoring platform, so that the monitoring platform sends the brake pressure status after inflation and the result of this remote inflation execution to the application client, so as to display a remote inflation completion prompt message and the brake pressure status after inflation on the application client.

[0006] In one possible implementation, before the receiving application client sends a remote inflation command through the monitoring platform, the method further includes: Receives a brake pressure query command sent by the application client through the monitoring platform; Obtain the brake air pressure status before inflation transmitted by the brake air pump; Determine whether the brake air pressure state before inflation meets the preset driving conditions, and obtain the air pressure judgment result; The pre-inflation brake air pressure status and the air pressure judgment result are sent to the monitoring platform, so that the monitoring platform sends the pre-inflation brake air pressure status and the air pressure judgment result to the application client, so that the application client can display corresponding information based on the air pressure judgment result.

[0007] In another possible implementation, the application client displays corresponding information based on the air pressure determination result, including: If the air pressure judgment result is that the preset driving conditions are met, an indication message indicating that no air replenishment is needed will be displayed, and the remote air inflation button will be grayed out. If the air pressure judgment result indicates that the preset driving conditions are not met, an indication message indicating that air needs to be replenished will be displayed, and the remote air inflation button will be illuminated.

[0008] In another possible implementation, obtaining the pre-inflation brake air pressure state transmitted by the brake pump includes: Determine the current dormant state of the heavy vehicle; If the current sleep state is a non-sleep state, then the brake air pressure state before inflation transmitted by the brake air pump is directly obtained. If the current sleep state is a sleep state, then the brake air pump is woken up, and the brake air pressure state before inflation is obtained from the brake air pump.

[0009] In another possible implementation, if the current sleep state is a sleep state, after sending the pre-inflation brake pressure status and the pressure judgment result to the monitoring platform, the method further includes: The brake air pump is instructed to enter a dormant state. In another possible implementation, the current vehicle state includes: current vehicle speed, parking switch status, and starting gear; determining whether the current vehicle state of the heavy vehicle meets the preset remote start conditions of the power system includes: Determine whether the current vehicle speed is zero, whether the parking switch is in the on state, and whether the start gear is in the off state; If the current vehicle speed is zero, the parking switch is in the open state, and the start position is in the off state, then the preset remote start condition is met.

[0010] In another possible implementation, the method further includes: If the preset remote start conditions are not met, the current vehicle status and the information of the items in the current vehicle status that do not meet the preset remote start conditions are sent to the monitoring platform, so that the monitoring platform sends the current vehicle status and the information of the items that do not meet the preset remote start conditions to the application client, so that the application client displays a prompt message that the preset start conditions are not met, as well as the information of the items that do not meet the preset remote start conditions.

[0011] Secondly, this application also provides a remote control system for a brake air pump, which includes: an application client, a monitoring platform, a vehicle terminal, a brake air pump, and a power system; wherein, the application client is communicatively connected to the monitoring platform, the monitoring platform is also communicatively connected to the vehicle terminal, and the vehicle terminal is also communicatively connected to the brake air pump and the power system. The vehicle-mounted terminal is used to execute the remote control method for the brake air pump described in any of the first aspects above.

[0012] Thirdly, embodiments of this application also provide an in-vehicle terminal, a processor, a storage medium, and a bus. The storage medium stores machine-readable instructions executable by the processor. When the in-vehicle terminal is running, the processor communicates with the storage medium via the bus, and the processor executes the machine-readable instructions to perform any of the brake pump remote control methods provided in the first aspect above.

[0013] Fourthly, embodiments of this application also provide a heavy-duty vehicle, including a vehicle body and an on-board terminal disposed on the vehicle body, wherein the on-board terminal is communicatively connected to the brake air pump and the power system on the vehicle body, and the on-board terminal is the on-board terminal described in the third aspect above.

[0014] The beneficial effects of this application are: In the remote control method, system, terminal, and vehicle for brake air pump provided in this application, the vehicle-mounted terminal can receive remote air pumping commands sent by the application client through the monitoring platform. If the current vehicle status of the heavy vehicle meets the preset remote start conditions, a start command is sent to the power system, causing the power system to enter the start state. The brake air pump automatically enters the air pumping working state until air pumping is completed. The terminal also receives the brake air pressure status after air pumping is completed and sends a shut-off command to the power system, causing the power system to enter the shut-off state. In addition, the brake air pressure status after air pumping and the result of this remote air pumping execution can be sent to the monitoring platform, which then sends the information to the application client to display a remote air pumping completion prompt and the brake air pressure status after air pumping on the application client. This method utilizes an onboard terminal, a monitoring platform, a brake air pump, a power system, and an application client to implement a remote control system for the brake air pump. Data interaction between these modules enables remote air pump inflation, allowing for remote air replenishment without requiring the user to enter the vehicle, thus improving vehicle usability. Furthermore, it incorporates precondition verification; a start command is only issued when preset remote start conditions are met, ensuring safe execution of remote inflation and guaranteeing that the brake pressure reaches the required standard for normal driving after inflation. Upon completion, the brake air pump automatically returns to the post-inflation brake pressure status and sends a shutdown command to the power system, synchronously stopping both the brake air pump and the power system, thus preventing unnecessary energy consumption.

Detailed Implementation

[0017] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. The components of the embodiments of the present application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely represents selected embodiments of the present application. All other embodiments obtained by those skilled in the art based on the embodiments of the present application without inventive effort are within the scope of protection of the present application.

[0018] The heavy-duty vehicles involved in the following embodiments of this application can be fuel-powered heavy-duty vehicles or new energy heavy-duty vehicles, such as pure electric heavy-duty vehicles, hybrid new energy heavy-duty vehicles, or fuel cell heavy-duty vehicles, etc., any type of energy heavy-duty vehicle.

[0019] To better understand the remote control method for a brake air pump provided in the embodiments of this application, the following explanation, in conjunction with the accompanying drawings, will describe a remote control system for a brake air pump provided in the embodiments of this application. Figure 1 This is a schematic diagram of a remote control system for a brake air pump provided in an embodiment of this application. Figure 1 As shown, the remote control system for the brake air pump includes at least: an application client 11, a monitoring platform 12, an on-board terminal 13, a brake air pump 14, and a power system 15. The application client 11 is communicatively connected to the monitoring platform 12, the monitoring platform 12 is also communicatively connected to the on-board terminal 13, and the on-board terminal 13 is also communicatively connected to the brake air pump 14 and the power system 15. The on-board terminal 13 is used to execute the remote control method for the brake air pump described in any of the following embodiments of this application.

[0020] The application client 11 can be a terminal device, such as a mobile terminal, that integrates a preset remote control application. This preset remote control application can be an application with at least a brake pump remote control function. In one application example, this application can be an application that only has a brake pump remote control function, also known as a remote brake inflation function. In another application example, this application can be an application with multiple remote control functions, including at least a brake pump remote control function, and may also have other remote control functions, such as remote vehicle unlocking, remote air conditioning, or remote air refilling.

[0021] The monitoring platform 12 is actually the server platform corresponding to the application client 11. The application client 11 can remotely communicate with the monitoring platform 12, for example, using a wireless Ethernet remote communication connection. The monitoring platform 12 also remotely communicates with the vehicle terminal 13. The vehicle terminal 13 can be a terminal installed in a vehicle that has network communication and data processing functions, such as a vehicle control device or a vehicle communication terminal. The vehicle terminal 13 can be a pre-installed vehicle terminal (i.e., a vehicle terminal installed before leaving the factory), or an aftermarket vehicle terminal or a plug-in vehicle terminal.

[0022] The vehicle terminal 13 can also communicate with the brake air pump 14 and the power system 15 within the vehicle. This communication connection can be, for example, via an in-vehicle Ethernet communication connection or an in-vehicle control bus communication connection. The in-vehicle control bus can be, for example, a Controller Area Network (CAN) bus. The power system 15 can be, for example, the engine system of a gasoline-powered heavy-duty vehicle or the power battery system of a new energy heavy-duty vehicle.

[0023] The application client 11 is responsible for human-computer interaction with the user, obtaining the user's input, and triggering remote commands to the monitoring platform 12. These remote commands can be, for example, brake pressure query commands or remote inflation commands.

[0024] The monitoring platform 12 can receive remote commands sent by the application client 11 and send the remote commands to the vehicle terminal 13. The vehicle terminal 13 is used to control the power system 15 according to the remote commands issued by the monitoring platform 12, such as controlling the power system to start or stop. The vehicle terminal 13 is also used to package the data transmitted by the brake pump, such as the brake pressure status, and report it to the monitoring platform 12 through the data reporting protocol after packaging. The power system 15 can perform corresponding actions after receiving the start or stop command transmitted by the vehicle terminal 13, such as entering the start state after receiving the start command, or entering the stop state after receiving the stop command. The brake pump 14 is responsible for transmitting the brake pressure status to the vehicle terminal 13 and performing corresponding work after the power system 15 starts or stops, such as performing the air pumping operation after the power system 15 starts, or stopping the air pumping operation after the power system 15 stops.

[0025] The monitoring platform 12 is responsible for parsing the data reported by the vehicle terminal 13. After parsing, the data is transmitted to the application client 11, so that the application client 11 can receive and display the brake air pressure status and the command execution results.

[0026] The remote control system for the brake air pump provided in this embodiment can interact with the application client 11, the monitoring platform 12, the vehicle terminal 13, the brake air pump 14, and the power system 15 to realize the remote air pumping function of the brake air pump.

[0027] The following examples illustrate the remote control method for the brake air pump provided in this application.

[0028] Figure 2 This is a flowchart illustrating the remote control method for a brake air pump provided in an embodiment of this application. This method can be implemented by an on-board terminal through data interaction with other modules in the remote control system for the brake air pump. Figure 2 As shown, the method may include: S201, The vehicle terminal receives remote inflation commands sent by the application client through the monitoring platform.

[0029] The application client can display a remote inflation interface. The application client can respond to remote inflation operations input by the user through this interface, triggering the generation and sending of a remote inflation command to the monitoring platform. Upon receiving the remote inflation command, the monitoring platform can forward it to the vehicle-mounted terminal.

[0030] For example, the remote inflation interface may display a remote inflation button, which users can click to input remote inflation operations.

[0031] S202. The vehicle terminal determines whether the current vehicle status of the heavy vehicle meets the preset remote start conditions of the power system.

[0032] After receiving a remote inflation command, the vehicle terminal can obtain the current vehicle status and determine whether the current vehicle status meets the preset remote start conditions of the power system. In a possible implementation, the current vehicle status can be used to determine whether the heavy vehicle is currently in a stationary, power-off parking state. If it is in a stationary, power-off parking state, the preset remote start conditions of the power system can be determined.

[0033] For example, the current vehicle status may include: current vehicle speed, parking switch status, and start gear. Accordingly, the vehicle terminal can determine whether the current vehicle speed is zero, whether the parking switch is on, and whether the start gear is off. If the current vehicle speed is zero, the parking switch is on, and the start gear is off, then the preset remote start conditions are met.

[0034] If the current vehicle speed is zero, it can be determined that the heavy vehicle is stationary; if the parking switch is in the on position, it can be determined that the heavy vehicle is parked. The start position can also be called the power position or the key power position. If the start position is off, it can be determined that the vehicle's power mode is off.

[0035] S203. If the preset remote start conditions are met, the vehicle terminal sends a start command to the power system, so that the power system is in the start state and the brake air pump automatically enters the air pumping state until the air pumping is completed.

[0036] The powertrain system can be either an engine system or a battery system. The on-board terminal can send a start command to the engine system to initiate power-start mode. Alternatively, the on-board terminal can send a start command to the battery system to connect it to the vehicle's high-voltage system, thus initiating high-voltage start mode. In other words, the powertrain system being in a start mode can either initiate power-start mode for the engine system or connect the battery system to the vehicle's high-voltage system.

[0037] In heavy-duty vehicles, the power system is pre-connected to the brake air pump. When the power system is started, it automatically activates the brake air pump to begin inflating the brake air reservoir. Once in operation, the brake air pump inflates the reservoir until inflation is complete. For example, complete inflation could mean the brake air reservoir is fully inflated.

[0038] S204. The vehicle terminal receives the brake air pressure status after the brake pump has finished inflating.

[0039] After the brake pump completes inflation, it can transmit the brake air pressure status to the vehicle terminal.

[0040] S205. The on-board terminal sends a shutdown command to the power system, causing the power system to enter the shutdown state.

[0041] After receiving the brake air pressure status after inflation, the vehicle terminal can send a shutdown command to the powertrain system. For example, the vehicle terminal can send a shutdown command to the engine system to shut it down, thus entering a power-off state; alternatively, the vehicle terminal can also send a shutdown command to the battery system to disconnect the vehicle's high-voltage system, thus entering a high-voltage deactivation state. In other words, the powertrain system being in a shutdown state can either enable the engine system to enter a power-off state or allow the battery system to disconnect the vehicle's high-voltage system.

[0042] S206. The vehicle terminal sends the brake air pressure status after inflation and the result of this remote inflation execution to the monitoring platform.

[0043] The vehicle-mounted terminal can package the brake air pressure status after inflation and the result of this remote inflation execution into a remote inflation data packet, and then send the remote inflation data packet to the monitoring platform.

[0044] S207 The monitoring platform sends the brake air pressure status after inflation and the result of this remote inflation execution to the application client.

[0045] S208 The application client displays a notification message indicating that remote inflation is complete, as well as the brake air pressure status after inflation.

[0046] After receiving the remote air inflation data packet, the monitoring platform can parse it to obtain the brake pressure status after inflation and the result of this remote inflation operation. This information is then sent to the application client for display. Upon receiving the data from the monitoring platform, the application client can display a notification message indicating that the remote inflation is complete, as well as the brake pressure status after inflation.

[0047] The remote control method for brake air pump provided in this application embodiment can receive a remote air pumping command sent by an application client through a monitoring platform from an on-board terminal. If the current vehicle status of the heavy vehicle meets the preset remote start conditions, a start command is sent to the power system, causing the power system to enter the start state. The brake air pump automatically enters the air pumping working state until air pumping is completed. The method also receives the brake air pressure status after air pumping is completed and sends a shut-off command to the power system, causing the power system to enter the shut-off state. In addition, the brake air pressure status after air pumping and the result of this remote air pumping execution can be sent to the monitoring platform, so that the monitoring platform can send it to the application client to display a remote air pumping completion prompt and the brake air pressure status after air pumping on the application client. This method utilizes an onboard terminal, a monitoring platform, a brake air pump, a power system, and an application client to implement a remote control system for the brake air pump. Data interaction between these modules enables remote air pump inflation, allowing for remote air replenishment without requiring the user to enter the vehicle, thus improving vehicle usability. Furthermore, it incorporates precondition verification; a start command is only issued when preset remote start conditions are met, ensuring safe execution of remote inflation and guaranteeing that the brake pressure reaches the required standard for normal driving after inflation. Upon completion, the brake air pump automatically returns to the post-inflation brake pressure status and sends a shutdown command to the power system, synchronously stopping both the brake air pump and the power system, thus preventing unnecessary energy consumption.

[0048] Secondly, the modules in this solution, including the vehicle terminal, monitoring platform, brake air pump, power system, and application client, have clear division of labor and standardized data and command transmission, ensuring stable system operation.

[0049] Based on the above embodiments, this application also provides a possible implementation method to remotely query the air pressure status of the brake air pump through remote control of the brake air pump. Figure 3 Another flowchart illustrating the remote control method for a brake air pump provided in this application embodiment. Figure 3As shown, before the vehicle terminal receives the remote inflation command sent by the application client through the monitoring platform in step S201 above, the method may further include: S301, the vehicle terminal receives the brake pressure query command sent by the application client through the monitoring platform.

[0050] The application client can respond to the user's brake pressure query operation input through the remote air inflation interface, triggering the generation and sending of a brake pressure query command to the monitoring platform. After receiving the brake pressure query command, the monitoring platform can forward the brake pressure query command to the vehicle terminal.

[0051] In one example, the remote air inflation interface of the application client may display a brake pressure status query button and a remote air inflation button. Before a brake pressure status query is performed, the brake pressure status query button is lit up, while the remote air inflation button is grayed out. Thus, the user can enter the brake pressure query operation by clicking the remote air inflation button. Alternatively, the user can enter the brake pressure query operation by clicking the brake pressure status query button.

[0052] In another example, the remote inflation interface of the application client may have only one operation button, which can be a one-click inflation button. This one-click inflation button combines the functions of checking brake pressure status and triggering remote inflation. Users can enter the brake pressure query operation by clicking the one-click inflation button.

[0053] S302, The vehicle terminal obtains the brake air pressure status before inflation transmitted by the brake air pump.

[0054] After receiving the brake pressure query command, the vehicle terminal can obtain the brake pressure status before inflation from the brake pump.

[0055] S303. The vehicle terminal determines whether the brake air pressure status before inflation meets the preset driving conditions and obtains the air pressure judgment result.

[0056] The air pressure judgment result is either that the brake air pressure status before inflation meets the preset driving conditions, or that the brake air pressure status before inflation does not meet the preset driving conditions.

[0057] In one possible implementation, if the remote inflation interface of the application client can display a brake pressure status query button and a remote inflation button, then after the vehicle terminal obtains the pressure judgment result, the method may further include: S304. The vehicle terminal sends the brake air pressure status and air pressure judgment result before inflation to the monitoring platform.

[0058] The vehicle-mounted terminal can package the brake air pressure status and air pressure judgment results before air inflation into an air pressure query data packet, and then send the air pressure query data packet to the monitoring platform.

[0059] S305 The monitoring platform sends the brake air pressure status and air pressure judgment results before inflation to the application client.

[0060] S306. The application client displays relevant information based on the air pressure judgment result.

[0061] After receiving the air pressure query data packet, the monitoring platform can parse it to obtain the pre-inflation brake air pressure status and the air pressure judgment result, and then send this information to the application client. Upon receiving the data from the monitoring platform, the application client can display corresponding information based on the air pressure judgment result.

[0062] Optionally, if the air pressure judgment result is that the preset driving conditions are met, the application client can display an indication that no air replenishment is needed and gray out the remote air inflation button. If the air pressure assessment result indicates that the preset driving conditions are not met, the application client will display an instruction message indicating that air needs to be replenished and will illuminate the remote air inflation button.

[0063] The indication message indicating that no air replenishment is needed could be: "The vehicle's current brake air pressure is sufficient, no air replenishment is needed"; the indication message indicating that air replenishment is needed could be: "The vehicle's current brake air pressure is insufficient, please replenish air".

[0064] If the air pressure reading indicates that the preset driving conditions are met, it can be determined that the brake air pump does not require additional air, and the remote air pump button can be grayed out, meaning it is not lit and cannot be clicked. If the air pressure reading indicates that the preset driving conditions are not met, it can be determined that the brake air pump requires additional air, and the remote air pump button can be illuminated, switching it from an unclickable state to a clickable state.

[0065] In another possible implementation, if the remote inflation interface of the application client has only one operation button, then after the vehicle terminal obtains the air pressure judgment result, the method may also include: If the air pressure judgment result is that the preset driving conditions are not met, it is not necessary to send the brake air pressure status before inflation and the air pressure judgment result to the application client through the monitoring platform. Instead, a remote inflation command is directly triggered, and the aforementioned methods S202-S207 are executed to realize the entire process of remote air replenishment of the brake air pump.

[0066] In this embodiment, the remote air inflation interface of the application client can be linked to a facility, allowing the application client to display corresponding information based on the air pressure judgment result. For example, the availability of the remote air inflation button can be controlled according to the brake air pressure status of the brake pump, and status prompts can be displayed synchronously. Furthermore, the entire process status can be visualized, the human-computer interaction is clear, the operation logic is rigorous and reliable, and the user's accidental touch can be effectively avoided. The remote brake air pressure status query and the triggering of remote air inflation can also be combined into one operation button, which facilitates user operation and improves the convenience of remote air replenishment.

[0067] In some possible implementation examples of the above embodiments, the process of the vehicle terminal obtaining the pre-inflation brake air pressure status transmitted by the brake air pump in step S302 of the aforementioned method may include: The vehicle terminal determines the current sleep state of the heavy vehicle. If the current sleep state is not sleep, it directly obtains the brake air pressure status before inflation transmitted by the brake air pump. If the current sleep state is sleep, it wakes up the brake air pump and obtains the brake air pressure status before inflation transmitted by the brake air pump.

[0068] It should also be noted that, when in sleep mode, after sending the pre-inflation brake air pressure status and pressure judgment result to the monitoring platform, the vehicle terminal may also include: notifying the brake air pump to enter sleep mode. After notifying the brake air pump to enter sleep mode, the vehicle terminal also enters self-sleep mode.

[0069] The method provided in this application embodiment can differentiate between vehicle sleep and non-sleep states for wake-up, data acquisition of brake pressure status, and implementation of sleep fallback logic during the process of remotely querying the brake air pump's brake pressure status, which helps reduce the vehicle's equipment power consumption.

[0070] Based on any of the above embodiments, this application also provides other possible implementation examples. Figure 4 Another flowchart of the remote control method for brake air pump provided in this application embodiment is shown below. Figure 4 As shown, the method may also include: S401. If the preset remote start conditions are not met, the vehicle terminal sends the current vehicle status and the information of the items in the current vehicle status that do not meet the preset remote start conditions to the monitoring platform.

[0071] The vehicle terminal can package the current vehicle status and information on items that do not meet the preset remote start conditions, obtain a feedback data packet, and send the feedback data packet to the monitoring platform.

[0072] S402 The monitoring platform sends the current vehicle status and information on items that do not meet the preset remote start conditions to the application client.

[0073] After receiving the feedback data packet, the monitoring platform can parse the feedback data packet to obtain the current vehicle status and the information of items that do not meet the preset remote start conditions, and then send the current vehicle status and the information of items that do not meet the preset remote start conditions to the application client.

[0074] S403. The application client displays a prompt message indicating that the preset remote startup conditions are not met, as well as entry information indicating that the preset remote startup conditions are not met.

[0075] The method provided in this application embodiment can also report the current vehicle status and the items that do not meet the preset remote start conditions to the application client through the monitoring platform when the current vehicle status does not meet the preset start conditions. This achieves accurate reporting of abnormal items and displays them intuitively on the application client, making the cause of the abnormality traceable, facilitating problem investigation, and improving operation and maintenance efficiency.

[0076] The following describes the apparatus, equipment, and storage medium used to implement the remote control method for the brake air pump provided in this application. The specific implementation process and technical effects are described above and will not be repeated below.

[0077] Figure 5 This is a schematic diagram of the remote control device for the brake air pump provided in the embodiments of this application, as shown below. Figure 5 As shown, the brake air pump remote control device 500 is applied to an in-vehicle terminal and may include: The remote communication module 501 is used to receive remote inflation commands sent by the application client through the monitoring platform.

[0078] The determination module 502 is used to determine whether the current vehicle status of the heavy vehicle meets the preset start-up conditions of the power system.

[0079] The vehicle-side communication module 503 is used to send a start command to the power system if the preset start conditions are met, so that the power system enters the start state, thereby causing the brake air pump to automatically enter the inflation working state until inflation is completed; receive the brake air pressure status after inflation sent by the brake air pump after inflation is completed, and send a shut-off command to the power system, so that the power system enters the shut-off state.

[0080] The remote communication module 501 is also used to send the brake pressure status after inflation and the result of this remote inflation execution to the monitoring platform, so that the monitoring platform sends the brake pressure status after inflation and the result of this remote inflation execution to the application client, so as to display the remote inflation completion prompt information and the brake pressure status after inflation on the application client.

[0081] Optionally, the remote communication module 501 is also used to receive the brake pressure query command sent by the application client through the monitoring platform before receiving the remote inflation command sent by the application client through the monitoring platform.

[0082] The vehicle-side communication module 503 is also used to obtain the brake air pressure status before inflation transmitted by the brake air pump.
