[0002] With the continuous advancement of automotive technology, modern vehicles are increasingly equipped with data transmission devices.

[0060] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0061] In one embodiment, such as Figure 1 As shown, a vehicle remote data extraction and control method is provided. This embodiment illustrates the application of this method to the control center of a device. It is understood that this method can also be applied to the vehicle's terminal, which may include a terminal device on the vehicle side of the vehicle remote data extraction and control system, such as a vehicle controller, a smart power distribution box, a TBOX (Telematics Box, in-vehicle remote information processing terminal), or one or more other devices. The method can also be applied to a remote server system, or to a system including a terminal and a server, and is implemented through interaction between the terminal and the server. In the implementation scenario of the embodiment provided in this application, the vehicle remote data extraction and control system can be a vehicle networking platform (typically a server-side system that communicates with the vehicle's terminal), with a locally existing vehicle monitoring host, vehicle controller, and smart power distribution box. In one embodiment, the method may include the following steps:

[0062] Step S100: Receive a request to extract vehicle data. If the vehicle is in the process of being powered down, receive a request to disconnect the vehicle. Obtain the power level of the data transmission device and the size of the vehicle data to be transmitted. The vehicle is used to charge the data transmission device.

[0063] Generally, if the vehicle is powered on (engine or high-voltage system is working normally, intelligent power distribution box is supplying power to components and the vehicle is charging the battery), the on-board communication box (TBOX) will upload the data to be transmitted to the vehicle networking platform in packets of varying sizes via the CAN network. The CAN network (Controller Area Network) is a serial communication protocol widely used in real-time communication, primarily in automotive electronics and industrial control. It features high-speed transmission and high reliability, and in the automotive technology field, it enables inter-module communication.

[0064] In one exemplary embodiment, the vehicle's power-off request may include an actively triggered power-off command, or a power-off request automatically generated by the vehicle system based on preset conditions. Specifically, an actively triggered power-off command may include turning off the car switch, removing the car key, etc.

[0065] In one exemplary embodiment, the vehicle data to be transmitted may include vehicle operation data, fault data, driving habit data, etc., that need to be uploaded in real time by the vehicle-to-everything (V2X) network. The data transmission device may include a battery or similar device that provides power to one or more devices such as the V2X platform, the vehicle's monitoring host, or the vehicle's monitor. The vehicle data to be transmitted may include various types of data information stored on the vehicle side, such as business information, fault information, and location information. The vehicle data may be a single piece of data or a data packet. The size of the vehicle data to be transmitted may include the number and size of the vehicle data packets to be transmitted.

[0066] Step S200: Based on the size of the vehicle data to be transmitted, determine the power required for the data transmission device to transmit the vehicle data. The required power includes the power required to start the data transmission device again after the transmission is completed.

[0067] In one exemplary embodiment, the amount of electricity required to complete the data transmission is calculated based on the size of the vehicle data to be transmitted and the transmission efficiency of the data transmission device. The transmission efficiency can be preset according to the performance parameters of the data transmission device to ensure the accuracy of the calculation.

[0068] In one exemplary embodiment, the required power may include the initial power required for the data transmission device to transmit vehicle data to be transmitted and the minimum power required for the data transmission device to operate. Specifically, the initial power can be calculated based on the size of the vehicle data to be transmitted and the transmission efficiency of the data transmission device, while the minimum power is the basic power required for the data transmission device to maintain normal operation. Adding the initial power and the minimum power yields the total power required for the data transmission device to complete the data transmission task. In some embodiments of this application, the required power may include the power required to restart the data transmission device after transmission is completed, ensuring that the battery does not run out of power.

[0069] In one exemplary embodiment, a dynamic energy consumption model can be established based on the size of historical vehicle data to be transmitted and the energy consumption of the data transmission device. The dynamic energy consumption model can then be used to determine the amount of electricity required to transmit the data to be transmitted.

[0070] In one exemplary embodiment, the amount of electricity required for the data transmission device to transmit vehicle data is calculated based on the running time and the power consumption rate of the data transmission device. The power consumption rate can be preset according to the performance parameters of the data transmission device to ensure the accuracy of the calculation. In this way, the amount of electricity required to complete the data transmission can be accurately determined, thereby providing a reliable basis for subsequently determining the vehicle's power outage time.

[0071] Step S300: Determine the power outage time of the vehicle based on the power level of the data transmission device and the required power level, and perform the corresponding power outage / sleep operation according to the power outage time after the vehicle's data transmission to the vehicle network platform is completed.

[0072] In one exemplary embodiment, if the power of the data transmission device is greater than the required power, it can be indicated that the remaining power of the data transmission device can meet the data transmission requirements, and therefore the vehicle can be directly powered off. If the power of the data transmission device is less than the required power, it can be indicated that the remaining power of the data transmission device cannot meet the data transmission requirements, and therefore the charging time of the vehicle for the data transmission device needs to be calculated to determine the power-off time of the vehicle.

[0073] After the vehicle's data is transmitted to the vehicle networking platform, a corresponding power-off / sleep operation is performed according to the power-off time. For example, when remote message retrieval is complete, the TBOX will send a completion command to the vehicle's CAN bus, and the vehicle controller will control all vehicle components and the intelligent control box to go into sleep mode according to the vehicle's status. The TBOX can also be controlled to go into sleep mode.

[0074] In one exemplary embodiment, when the battery power of the data transmission device is less than the required battery power, the additional charging time required can be calculated based on the difference between the current battery power of the data transmission device and the required battery power. Then, combined with the current state of the vehicle (such as engine running status, remaining battery power, etc.), a reasonable power-off time that satisfies the data transmission requirements without excessively consuming the vehicle's battery power is determined. It is understood that when the engine is running, the engine replenishes the vehicle battery power. Therefore, based on the engine running status, the preset maximum battery power that the vehicle battery can consume, and the battery power of the data transmission device, the maximum battery power that can be provided for data transmission can be determined. The data transmission speed is then dynamically adjusted based on the provided maximum battery power. Specifically, when the required battery power is greater than the provided maximum battery power, the maximum operating time of the data transmission device under the provided maximum battery power can be predicted. Based on the size of the vehicle data and the maximum operating time of the data transmission device, the data transmission speed is determined, thereby achieving the goal of meeting data transmission requirements while controlling vehicle battery power consumption. After determining the power-off time, the control center can send a power-off command to the vehicle, controlling the vehicle to perform a power-off operation at the specified time to ensure the integrity of data transmission and the rational use of vehicle battery power.

[0075] In the aforementioned vehicle remote data extraction and control method, in response to a vehicle power-off request, the required power supply for the data transmission device to transmit the vehicle data is determined based on the size of the vehicle data to be transmitted. Then, based on the required power supply and the power supply of the data transmission device, the power-off time is determined. This method enables a reasonable assessment of the data transmission needs of the data transmission device before the vehicle's power is cut off, and adjusts the power-off time based on the assessment results to ensure the integrity of data transmission and the effective utilization of vehicle power. This method not only improves the reliability of data transmission but also avoids potential security risks caused by incomplete data transmission. Furthermore, by precisely controlling the vehicle's power-off time, it can effectively save vehicle power and extend the vehicle's service life.

[0076] In one embodiment, such as Figure 2 As shown, determining the power required for the data transmission device to transmit the vehicle data based on the size of the vehicle data to be transmitted includes:

[0077] Step S201: Determine the running time for the data transmission device to transmit the vehicle data based on the size of the vehicle data to be transmitted.

[0078] Step S202: Based on the running time, determine the power required for the data transmission device to transmit the vehicle data to be transmitted.

[0079] In one exemplary embodiment, the time for the data transmission device to transmit the vehicle data to be transmitted can be determined based on the size and transmission speed of the vehicle data, and the time for the data transmission device to transmit the vehicle data to be transmitted, the running time of the data transmission device to transmit the vehicle data to be transmitted, etc., can be utilized.

[0080] In this embodiment, the operating time of the data transmission device is determined by the size of the vehicle data to be transmitted, and the power required for the data transmission device to transmit the vehicle data is determined based on the operating time. This achieves more precise control over the vehicle power outage time. In this way, the data transmission needs of the data transmission device can be more accurately assessed, thus providing strong support for determining a reasonable power outage time.

[0081] Generally, data size affects transmission speed, but existing solutions for remote vehicle data extraction consider the impact of "data importance classification" and "transmission interruption recovery" on remote vehicle data extraction. Therefore, in some other embodiments provided in this disclosure, priority data information can be pre-added to the vehicle data, which includes data priority data. The method further includes:

[0082] If the required power is lower than the preset start-up protection threshold, the transmission speed of the data transmission device will be reduced or the transmission of low-priority data will be suspended during the process of transmitting the vehicle's data to the vehicle network platform, until the current power of the data transmission device is restored to above the start-up protection threshold.

[0083] The start-up protection threshold can be used to ensure that the vehicle can start normally next time. The priority data information can be labeled by data type or custom-defined tags, which can characterize the importance of the vehicle data itself or the order in which data is transmitted, such as the data transmission priority of fault data > operation data > log data.

[0084] This disclosed embodiment provides a proactive prevention mechanism for battery depletion in a vehicle data remote advance control system. During data transmission, the battery status is monitored in real time. When the battery charge falls below the "next start threshold," priority is given to ensuring the battery's basic charge level, and the data transmission strategy is dynamically adjusted (e.g., reducing transmission speed or pausing low-priority data transmission). This embodiment avoids the vehicle failing to start due to excessive battery drain during data transmission. It also addresses the potential loss of critical data due to insufficient battery power in existing technologies, improving transmission efficiency and ensuring the reliability of critical data transmission.

[0085] In one embodiment, determining the power required for the data transmission device to transmit the vehicle data based on the size of the vehicle data to be transmitted includes:

[0086] The size of the vehicle data to be transmitted is input into a preset dynamic energy consumption model to predict the power required to transmit the vehicle data. The dynamic energy consumption model is obtained by: acquiring the size of historical vehicle data to be transmitted and the actual energy consumption of the corresponding data transmission device; inputting the size of the historical vehicle data to be transmitted into an initial dynamic energy consumption model; outputting the prediction result; and iteratively adjusting the initial dynamic energy consumption model based on the difference between the prediction result and the actual energy consumption to obtain the dynamic energy consumption model.

[0087] In one exemplary embodiment, the energy consumption may include the amount of electricity required to transmit vehicle data to be transmitted; the initial dynamic energy consumption model may be a prediction model built based on algorithms such as machine learning or deep learning, used to initially predict the energy consumption required to transmit vehicle data of different sizes.

[0088] In one exemplary embodiment, the specific method for acquiring the dynamic energy consumption model may include: collecting a large amount of historical data on the size of vehicles to be transmitted and the corresponding actual energy consumption data of the data transmission equipment; this data may come from previous vehicle operation records, etc. This historical data is input into an initial dynamic energy consumption model to preliminarily predict the energy consumption required to transmit vehicle data of different sizes. After the model outputs the prediction result, it is compared with the actual energy consumption data to calculate the prediction error. Based on this error, the parameters of the initial dynamic energy consumption model are adjusted to reduce the prediction error and improve the model's accuracy. This process is iterative, requiring multiple inputs of historical data and adjustments to the model parameters until the model's prediction result is sufficiently close to the actual energy consumption data, reaching a preset accuracy requirement (e.g., error and accuracy within a preset range). Finally, after multiple iterative adjustments, an optimized dynamic energy consumption model is obtained. This model can more accurately predict the power required to transmit vehicle data of different sizes, providing strong support for subsequent equipment control.

[0089] In this embodiment, the required power consumption for transmitting the vehicle data to be transmitted is predicted by inputting the vehicle data to be transmitted into a preset dynamic energy consumption model. This achieves intelligent power consumption prediction of the vehicle data to be transmitted, improving the accuracy and efficiency of power consumption prediction. Furthermore, using a dynamic energy consumption model for power consumption prediction reduces interference from human factors, making the prediction results more objective and reliable.

[0090] In one embodiment, such as Figure 3 As shown, determining the required power for the data transmission device to transmit data to the vehicle to be transmitted, based on the size of the vehicle data, includes:

[0091] Step S211: If the size of the vehicle data to be transmitted is less than a preset threshold, the vehicle data to be transmitted is transmitted at a preset first transmission speed, and the power required for the data transmission device to transmit the vehicle data to be transmitted is determined.

[0092] Step S212: If the size of the vehicle data to be transmitted is greater than a preset threshold, determine the second transmission speed based on the size of the vehicle data to be transmitted and the preset transmission time, and use the second transmission speed to transmit the vehicle data to be transmitted.

[0093] In one exemplary embodiment, the preset transmission time may include a preset maximum transmission time, i.e., the maximum allowed duration during data transmission, to ensure that excessive vehicle battery consumption is not caused by prolonged data transmission. The preset threshold may include obtaining a preset maximum transmission time and a preset transmission speed, and obtaining a preset data size based on the preset maximum transmission time and preset transmission speed, i.e., the preset threshold. The fact that the size of the vehicle data to be transmitted is less than the preset threshold may include transmitting the vehicle data at a preset transmission speed, requiring a transmission time less than the preset maximum transmission time, etc. Therefore, the battery power required for the data transmission device to transmit the vehicle data can be determined by the size of the vehicle data to be transmitted and the preset transmission time. The fact that the size of the vehicle data to be transmitted is greater than a preset threshold may include transmitting the vehicle data at a preset transmission speed, or the required transmission time being greater than a preset maximum transmission time. In this case, to ensure that the transmission time does not exceed the preset maximum transmission time, the required transmission speed can be determined based on the size of the vehicle data and the preset maximum transmission time to ensure that all the vehicle data to be transmitted is transmitted within the maximum transmission time. It can be understood that in this case, the transmission time is the preset maximum transmission time, and the power consumption required by the transmission device to transmit the vehicle data to be transmitted can be determined based on the maximum transmission time.

[0094] In this embodiment, the required power consumption for transmitting vehicle data is determined by judging the size of the vehicle data to be transmitted and selecting different transmission speeds and strategies based on the judgment result. This method can more flexibly adapt to different data transmission needs, ensuring that data transmission tasks are completed within a reasonable time while avoiding excessive consumption of vehicle power. When the vehicle data to be transmitted is small, a preset first transmission speed is used to ensure data transmission efficiency and stability; while when the vehicle data to be transmitted is large, the transmission speed is dynamically adjusted according to the data size and a preset transmission time, allowing data transmission to be completed within a limited time, thereby better balancing data transmission efficiency and vehicle power consumption.

[0095] In one embodiment, such as Figure 4 As shown, determining the power outage time of the vehicle based on the power level of the data transmission device and the required power includes:

[0096] Step S301: If the power of the data transmission device is less than the required power, determine the additional power requirement of the data transmission device for transmitting the vehicle data to be transmitted based on the power of the data transmission device and the required power.

[0097] Step S302: Determine the vehicle's operating time based on the additional power demand, and determine the vehicle's power outage time based on the vehicle's operating time.

[0098] In one exemplary embodiment, the additional power requirement can be calculated by the difference between the current power level of the data transmission device and the required power level. Specifically, the remaining power level of the data transmission device can be determined first, and then the current power level can be subtracted from the required power level to obtain the additional power requirement. This additional power requirement can represent the power that the data transmission device needs to obtain from the vehicle to complete the data transmission task. The time the vehicle needs to run can also be calculated based on the additional power requirement and the vehicle's charging efficiency to meet the additional power requirement of the data transmission device. The vehicle's charging efficiency can be preset based on the vehicle's performance parameters to ensure the accuracy of the calculation. The time the vehicle needs to run can be obtained by dividing the additional power requirement by the vehicle's charging efficiency. After determining the time the vehicle needs to run, a reasonable power outage time can be determined based on this time and possible delay factors (such as start-up time, driver reaction time, etc.). This power outage time should be long enough to ensure that the data transmission device can obtain the required additional power and complete the data transmission task, but not too long to avoid unnecessary vehicle power consumption. After determining the power outage time, the control center can send a command to the vehicle to control the vehicle to perform a power outage operation at the specified time.

[0099] In this embodiment, when the power supply of the data transmission device is less than the required power supply, the additional power demand of the data transmission device is determined, and the vehicle's operating time is further determined, thereby determining the vehicle's power outage time. This achieves more precise control over the vehicle's power outage time. In this way, while ensuring data transmission integrity, vehicle power consumption can be maximized, improving energy efficiency. The control center can calculate a reasonable power outage time in real time based on parameters such as the current power supply of the data transmission device, the required power supply, and the vehicle's charging efficiency, and send a power outage command to the vehicle, thus achieving precise control over the vehicle's power outage time. This method not only improves the reliability of data transmission but also further optimizes the vehicle's energy management.

[0100] The above embodiments provide a method for estimating energy consumption based on the parameter of "data size to be transmitted". Traditional calculations of battery operating time typically ignore dynamic factors during transmission (such as transmission speed fluctuations and real-time power consumption changes of the device). Furthermore, they do not incorporate a feedback correction mechanism based on historical data, nor do they differentiate the real-time status of data transmission devices (such as TBOXes) (e.g., the impact of current battery level and aging on power consumption), making dynamic adjustments based on actual energy consumption deviations impossible. These factors lead to some traditional methods failing to accurately match actual scenarios in energy consumption calculations, resulting in a large error range.

[0101] In other embodiments provided in this disclosure, the input parameters of the dynamic energy consumption model may include: the total size of the data to be transmitted, the real-time transmission power of the TBOX (which usually changes dynamically with the transmission speed), the current discharge efficiency of the battery (positively correlated with the remaining power), and the preset wake-up redundancy power (which can ensure that the battery can still support at least 3 remote wake-up requests after the data transmission is completed).

[0102] The power consumption required by the dynamic energy consumption model is calculated as follows: Total transmission power consumption = (Total data size / Real-time transmission speed) × Real-time transmission power ÷ Discharge efficiency + Wake-up redundancy power.

[0103] If the current battery charge is greater than or equal to the required charge, then it is determined that no DC-DC charging is needed; otherwise, calculate the amount of charge that the DC-DC needs to replenish (required charge - current charge), and determine its working time based on the charging power of the DC-DC (e.g., 200W).

[0104] The dynamic energy consumption model in this embodiment can be a built-in model algorithm of the vehicle controller. It can collect the transmission speed of the TBOX in real time via the CAN network (which can be periodically reported by the TBOX), the remaining battery power, and the discharge efficiency curve (which can be pre-stored in the controller ROM and dynamically recalled as the battery power changes). The input parameters of the dynamic energy consumption model can be collected or calculated. Generally, when the battery power is low, the charging efficiency of the DC-DC converter may decrease (e.g., from 90% to 80%). This solution incorporates this variable into the energy consumption calculation ("Required power = Transmission energy consumption ÷ Charging efficiency"), thereby solving the problem that traditional methods may ignore the dynamic changes in charging efficiency and directly estimate based on a fixed efficiency, leading to amplified errors.

[0105] The calculation method provided in this implementation, which is total transmission energy consumption = (total data size / real-time transmission speed) × real-time transmission power ÷ discharge efficiency + wake-up redundant power, further improves the accuracy of energy consumption calculation (according to relevant data simulation calculations, it can be improved from the traditional ±20% to ±5%). This can avoid transmission interruption due to underestimating energy consumption or DCDC failure due to overestimating energy consumption.

[0106] The aforementioned DC-DC (Direct Current to Direct Current) converter is also commonly referred to as a DC transformer. In this technical field, the voltage provided by the vehicle battery (e.g., 12V) needs to be converted by the DC-DC converter to the voltage required by different devices (e.g., providing 5V or 3.3V to the onboard computer or sensors). The improved solution in this embodiment can ensure redundant power for wake-up. For example, based on historical wake-up records, the average energy consumption of a single wake-up is calculated (e.g., 5Wh). In some embodiments, it can be calculated as 3 times redundant (15Wh), which can effectively ensure that the battery can still respond to emergency wake-up requests after the transmission is completed. This embodiment uses a wake-up redundant power design, which can make the remote wake-up success rate reach 100%, solving the problem of the battery being depleted and unable to wake up after transmission in traditional solutions.

[0107] This solution addresses the core shortcomings of traditional energy consumption calculations—namely, "single parameters, lack of feedback, and detachment from actual operating conditions"—through a three-tiered improvement process: "multi-parameter modeling → iterative optimization based on historical data → real-time operating condition adaptation."

[0108] In one embodiment, the required power further includes: a second required power for starting the data transmission device again after the transmission is completed, the second required power being used to start the data transmission device upon receiving a request for the next data transmission after the data transmission is completed.

[0109] In one exemplary embodiment, the second required power may include the minimum power required for the data transmission device to operate. The data transmission device can respond to data transmission requests remotely sent by a mobile terminal, and therefore can retain the minimum power required for its operation; this allows it to be activated upon receiving a data transmission request. In another exemplary embodiment, the power supply for the data transmission device can be connected to a vehicle. The mobile terminal can remotely send data transmission requests to the vehicle network. The second required power is used to power on the vehicle network and activate the data transmission device, further determining whether the vehicle needs to charge the data transmission device.

[0110] In one exemplary embodiment, the second required power may include the basic power required for the data transmission device to maintain normal operation, and this value can be preset according to the specifications and performance of the data transmission device. Adding the initial required power and the second required power yields the total power required for the data transmission device to complete this data transmission task.

[0111] In this embodiment, when determining the required power, a second required power level is also considered for starting the data transmission device again after the transmission is completed. This design ensures that the data transmission device retains sufficient power to respond to subsequent transmission requests even if the vehicle loses power after completing a transmission task. This approach not only improves the utilization rate of the data transmission device but also ensures the continuity and timeliness of data transmission.

[0112] In one embodiment, such as Figure 5 As shown, the method further includes:

[0113] Step S401: When the vehicle and data transmission device are in a power-off state, power on the data transmission device in response to the data transmission request sent by the terminal.

[0114] Step S402: Determine the working time of the vehicle based on the data transmission request and the battery level of the data transmission device.

[0115] In one exemplary embodiment, when both the vehicle and the data transmission device are powered off, the control center can listen for and respond to data transmission requests from terminals. This request can be initiated by a user via a mobile phone, smartwatch, or other device to request the transmission of certain vehicle data. Upon receiving the request, the control center will power on the data transmission device to prepare for data transmission.

[0116] In one exemplary embodiment, the data transmission request may include the data to be transmitted; based on the data transmission request, the size of the vehicle data to be transmitted is determined, and based on the size of the vehicle data, the required power of the data transmission device is determined, and based on the power of the data transmission device, the vehicle's operating time is determined, etc.

[0117] In this embodiment, the data transmission device is powered on in response to a data transmission request from the terminal, and the vehicle's operating time is determined based on the data transmission request and the device's battery level. This enables remote control of vehicle data transmission, improving the flexibility and convenience of data transmission. Even when both the vehicle and the data transmission device are powered off, the control center can quickly respond to data transmission requests from the terminal and power on the data transmission device. In this way, users can request vehicle data transmission anytime, anywhere, without worrying about whether the vehicle or the data transmission device is operational. Simultaneously, the control center can intelligently determine the vehicle's operating time based on the data transmission request and the device's battery level to ensure successful data transmission. This remote control method improves data transmission efficiency.

[0118] In one embodiment, the method further includes:

[0119] In response to powering on the vehicle, the data transmission device is charged using the vehicle.

[0120] In one exemplary embodiment, the power-on operation may include activating the vehicle's main power supply to provide power to the data transmission device. In one case, the vehicle's main power supply may be designed to automatically cut off power when the vehicle is off or in standby mode to save energy. When data transmission is required, the control center can send a command to activate the vehicle's main power supply, thereby providing the necessary power to the data transmission device. This process ensures that the data transmission device can quickly obtain sufficient power support to complete the data transmission task when needed. In another exemplary embodiment, the charging operation may further include monitoring the battery status of the data transmission device. The control center can monitor the battery level of the data transmission device in real time to ensure that it has sufficient power support during data transmission. If the battery level is insufficient, the control center can adjust the vehicle's charging strategy in a timely manner, such as increasing charging time or improving charging efficiency, to ensure the smooth completion of data transmission. In this way, the control center can intelligently manage the vehicle's power resources to meet the needs of the data transmission device while ensuring that the vehicle's power supply is not unnecessarily affected.

[0121] In one exemplary embodiment, charging in response to powering on the vehicle may further include considering the vehicle's current state. For example, if the vehicle is currently in motion, the control center may need to adjust the charging strategy to avoid adversely affecting the vehicle's operation. This may include limiting charging power or adjusting charging time to ensure that the charging operation does not interfere with the normal operation of the vehicle. In this way, the control center can ensure data transmission is completed while also considering vehicle safety and driving efficiency.

[0122] In this embodiment, by responding to the vehicle's power-on operation, the vehicle is used to charge the data transmission equipment, ensuring sufficient power support for the data transmission equipment while remotely controlling the vehicle's data transmission. This approach improves the reliability and flexibility of data transmission and optimizes vehicle energy management. In practical applications, the control center can intelligently determine the charging strategy based on factors such as the power requirements of the data transmission equipment, the vehicle's current status, and charging efficiency, and send corresponding instructions to the vehicle, thereby achieving intelligent management of both the vehicle and the data transmission equipment.

[0123] In an exemplary embodiment, the vehicle remote data extraction control can also be implemented in the following manner, specifically including: after the vehicle network platform issues a remote message extraction command and the corresponding download time, the vehicle network platform can send the command to the vehicle monitoring host with local storage. After successfully handshaking with the vehicle monitoring host, the monitoring host can perform different processing according to different states; when the vehicle is powered on, the transmitter or high voltage is working normally, the smart power distribution box can supply power to the components normally, and the vehicle can charge the battery normally. At this time, the on-board communication box (TBOX) can directly upload data to the monitoring platform through the controller area network (CAN network) and upload it according to the size of the extracted data; when the driver turns off the vehicle power, the vehicle controller can determine the time required to upload the data by the size and number of data packets uploaded to the vehicle network platform. Specifically, there are two scenarios: If the upload time is long and requires a significant amount of battery power, the required operating time of the DC-DC converter (DCDC, used to charge the battery using the vehicle's power supply system) in the multi-function controller can be calculated based on the power consumption. The DCDC will then be powered down after operating for a certain period. If the vehicle controller determines that the extraction time does not require the DCDC to charge the battery based on the size and number of data packets extracted remotely, and the battery power is sufficient to meet the data extraction needs without affecting the vehicle's next normal operation, the vehicle controller can normally control the vehicle to reduce high voltage according to the power-down logic. At this time, the smart power distribution box is in the vehicle's powered-on state, normally supplying power to the TBOX until the TBOX completes data extraction and upload and then enters a sleep state.

[0124] In one exemplary embodiment, the vehicle can also remotely control data transmission via a monitoring host. Specifically, if the vehicle monitoring host is in sleep mode and the vehicle is powered off, the vehicle network platform can remotely wake up the monitoring host by issuing a remote data extraction command. The monitoring host then sends a data extraction message to the vehicle's CAN network, waking up the intelligent power distribution box and the vehicle controller. The vehicle controller then determines whether high voltage needs to be activated for vehicle control based on the actual vehicle conditions. After remote data extraction is complete, the monitoring host sends a data extraction completion message to the vehicle's CAN network. The intelligent power distribution box and the vehicle controller then power down the vehicle and enter sleep mode. The power supply for the vehicle controller, intelligent power distribution box, and monitoring host comes directly from the battery, and this power supply is not controlled by the vehicle's shut-off gate.

[0125] In other embodiments of the method provided in this disclosure, the data transmission device is provided with an adaptive power supply module, which includes:

[0126] Multiple independently controllable power supply circuits, each equipped with a current sensor and a solid-state relay;

[0127] If the vehicle data extraction request includes a data extraction list, then during the process of transmitting the vehicle data to the vehicle networking platform, the method further includes:

[0128] The control data transmission device only turns on or wakes up the power supply circuit that matches the data extraction list, while other circuits remain disconnected.

[0129] The multiple independently controllable power supply circuits can correspond to different components, such as TBOX circuits, ECU circuits in vehicle control, sensor circuits, indicator light circuits, sound control circuits, etc. In this embodiment, while ensuring the vehicle can operate normally, only necessary modules are activated upon wake-up, and only the power supply circuits matching the data extraction list of this application are turned on or woken up, minimizing the power supply to hardware unrelated to data extraction and reducing battery energy consumption.
