Description

Technical Field

[0001] The present invention relates to a remote intelligent control system and method for new energy trucks, and relates to the technical field of intelligent control of new energy vehicles. Background Art

[0002] With the advancement of intelligent and connected vehicles, the demand for remote monitoring and control of vehicles over the internet is growing. The rapid adoption of new energy vehicles has driven the booming car rental industry across various models. To effectively regulate this industry, remote data monitoring and vehicle locking are essential. Furthermore, existing technologies for remote vehicle control only offer single functions, such as window raising and lowering and push-button start, failing to integrate multiple functions. This remote control capability falls far short of meeting current demands for multi-functional remote vehicle control. Furthermore, existing vehicles lack real-time vehicle and equipment monitoring and remote fault diagnosis and warning capabilities, preventing drivers from quickly identifying safety hazards and resolving faults promptly. Summary of the Invention

[0003] In order to solve the above technical problems, the purpose of the present invention is to provide a remote intelligent control system and method for new energy trucks. The specific technical solutions are as follows:

[0004] A remote intelligent control method for new energy trucks is disclosed. The client sends a remote control request to the TSP platform. The TSP platform receives the remote control request and sends it to the EVTBOX on the vehicle end. The EVTBOX and the VCU perform remote control security authentication. The VCU sends a control instruction to the vehicle electrical system, which performs power control and body control. After the vehicle electrical system executes the instruction action, it sends the execution result to the bus in the form of a CAN signal. The EVTBOX detects the bus status signal, determines the remote control execution result, and feeds it back to the TSP platform. The TSP platform then feeds back the remote control execution result to the client.

[0005] Preferably, the client is a mobile phone APP, and the TSP platform is connected to the client and EVTBOX through base stations and 5G signal radio communication; after the mobile phone APP user downloads the APP through the QR code or the company's official mall platform, enters the APP login interface, enters the ID number, mobile phone number, car license plate number, vehicle VIN number, and sets the login password to complete the registration; when using, enter the login password, enter the APP program after verification by the TSP platform, and execute user instructions.

[0006] Preferably, the remote control security authentication is as follows: EVTBOX sends a remote control request message without a key to VCU. After VCU receives the remote control message without a key sent by EVTBOX, it resets the seed and sends a remote control verification message to EVTBOX. After EVTBOX calculates the key based on the seed according to the remote control verification message sent by VCU, it sends a remote control request message with a key to VCU. After VCU receives the remote control request message with a key, it verifies whether the key is correct. If the key is correct, VCU sends a remote control verification success message to EVTBOX; if the key is incorrect, VCU sends a remote control verification failure message to EVTBOX; when EVTBOX receives the remote control verification success signal, the remote control security authentication process passes; when EVTBOX receives the remote control verification failure signal, the process jumps to the initial state and re-checks. After two verification failures, the remote control security authentication process fails; if the verification time exceeds 1 minute, it is considered that the verification has failed and the remote control security authentication fails.

[0007] Preferably, before the TSP platform receives the remote control request and sends it to the EVTBOX on the vehicle side, the EVTBOX monitors the current vehicle status information and uploads it to the TSP platform through the SIM card. The TSP platform records and saves the last data before the EVTBOX goes into sleep in real time. The TSP platform determines whether the remote control conditions are currently met based on the data before the EVTBOX goes into sleep. When the TSP platform receives that the current vehicle is in the door closed state, window closed state, vehicle off state, vehicle non-charging state, and handbrake pulled up state, the platform sends a remote control request to the EVTBOX on the vehicle side.

[0008] Preferably, the EVTBOX needs to wake up the VCU before performing remote control security authentication with the VCU. Specifically, the EVTBOX and the VCU establish an OSEK network ring and wake up the VCU through a CAN signal. When the EVTBOX receives a network management signal from the VCU and the Alive indicator bit is activated, the VCU is considered to have woken up.

[0009] Furthermore, the user instructions include remote control instructions and remote monitoring instructions; the remote control instructions include remote door unlocking, remote window lifting, remote vehicle starting, remote vehicle search control, remote air conditioning control, remote electric heating control, remote charging control, and car anti-theft control; the remote monitoring instructions include real-time vehicle positioning, real-time display of vehicle status information, historical trajectory playback, energy consumption prompts, and fault alarm reminder functions.

[0010] Furthermore, the remote charging control includes power battery charging. The power battery charging requires the charging gun to be in normal status. The user sends a pre-charging time instruction on the mobile phone APP. After receiving it, the TSP platform determines whether the current time is consistent with the scheduled time. If not, the charging instruction is not sent to the EVTBOX, and the vehicle network and controller are kept in sleep state; if they are consistent, the control instruction is sent to the vehicle EVTBOX, and the EVTBOX forwards the control instruction to the VCU. The VCU wakes up the BMS and ICU through hard wire or network. At the same time, the VCU determines whether the current vehicle status information meets the charging conditions. If so, it sends a charging instruction to the BMS and ICU. The BMS and ICU control their own controller contactors to close and execute charging and feedback the execution status. The VCU forwards the status to the EVTBOX through the CAN network. The EVTBOX and TSP platform feedback the execution status to the mobile phone APP, and the mobile phone APP displays the current charging status.

[0011] Furthermore, the remote charging control also includes low-voltage battery charging. The EVTBOX has a timed wake-up function. The TSP platform can regularly detect the current battery voltage information and upload the monitoring information to the mobile phone APP. The user can set the low battery voltage reminder threshold on the mobile phone APP. When the TSP platform detects that the current battery voltage is lower than the low battery voltage reminder threshold set by the user, a pop-up window will remind the user whether the current battery voltage is too low and recharging is required. The user decides whether to execute the low-voltage battery recharging function based on the user's request. If the low-voltage battery recharging function is selected, the TSP platform will send a command to the EVTBOX on the vehicle side. The EVTBOX and the VCU will perform a safety information verification. After the verification is passed, the VCU will wake up the ICU and BMS and control the DCDC to recharge the battery. At the same time, the TSP platform will detect the current battery voltage in real time and determine whether to stop recharging. If the conditions are met, a stop recharging command will be issued. The VCU will forward the recharging status to the EVTBOX via the CAN network. The EVTBOX and the TSP platform will feedback the execution status to the mobile phone APP, and the mobile phone APP will display the current charging status.

[0012] Furthermore, real-time vehicle positioning uses the GPS antenna and SIM card configured on the EVTBOX platform to locate the current vehicle location information. This information is then transmitted to the mobile app via the TSP platform via the internet, informing the user of the current vehicle location information. When replaying historical tracks, the TSP platform will record and save the current location information in real time while the vehicle is being positioned in real time. Data playback allows users to review the path taken during a specific time period.

[0014] A client, configured to send user instructions;

[0015] The TSP platform is used to receive requests corresponding to user instructions sent by the client and send them to EVTBOX;

[0017] VCU, the VCU is used to forward control instructions to various controllers of the vehicle electrical system;

[0018] The automobile electrical system executes the action corresponding to the control instruction. After executing the instruction action, the automobile electrical system sends the execution result to the bus in the form of a CAN signal. The EVTBOX detects the bus status signal to determine the remote control execution result and feeds it back to the TSP platform. The TSP platform feeds back the remote control execution result to the client.

[0019] This invention leverages the internet of big data, a remote monitoring platform, and an onboard terminal to provide timely access to vehicle-related information and facilitate user monitoring and control of vehicle information using a mobile app. This invention integrates multiple remote control and monitoring functions, enabling remote control of various vehicle functions through a mobile app. It also provides real-time monitoring and remote fault diagnosis and early warning, allowing drivers to quickly identify safety hazards and promptly troubleshoot, ensuring driving safety.

[0026] TSP platform: vehicle terminal service platform

[0027] EVTBOX: Remote Monitoring Terminal

[0032] ICU: All-in-one intelligent control unit

[0033] like Figure 1 As shown, a new energy truck remote intelligent control system includes:

[0034] A client, configured to send user instructions;

[0035] The TSP platform is used to receive requests corresponding to user instructions sent by the client and send them to EVTBOX;

[0036] EVTBOX, which is used to receive requests from the TSP platform, wake up the VCU, and perform remote control security authentication with the VCU;

[0037] VCU, the VCU is used to forward control instructions to various controllers of the vehicle electrical system;

[0038] The automobile electrical system executes the action corresponding to the control instruction. After executing the instruction action, the automobile electrical system sends the execution result to the bus in the form of a CAN signal. The EVTBOX detects the bus status signal to determine the remote control execution result and feeds it back to the TSP platform. The TSP platform feeds back the remote control execution result to the client.

[0039] like Figure 2 As shown, a remote intelligent control method for new energy trucks is shown. The client sends a remote control request to the TSP platform. The TSP platform receives the remote control request and sends it to the EVTBOX on the vehicle end. The EVTBOX and the VCU perform remote control security authentication. The VCU sends a control command to the vehicle electrical system, which performs power control and the vehicle electrical system performs body control. After the vehicle electrical system executes the command action, it sends the execution result to the bus in the form of a CAN signal. The EVTBOX detects the bus status signal to determine the remote control execution result and feeds it back to the TSP platform. The TSP platform then feeds back the remote control execution result to the client, forming a closed loop. This invention is applicable to a full range of new energy vehicle models and can enable users to remotely operate and monitor the vehicle.

[0040] The client is a mobile phone APP, which is responsible for human-computer interaction. The user operates the mobile phone APP to select the current instruction to be executed and click to confirm; the TSP platform is connected to the client and EVTBOX through base stations and 5G signal radio communication, and receives the operation instructions issued by the mobile phone APP. The TSP platform server receives the control instruction and sends it to the vehicle terminal EVTBOX through 5G signals; after receiving the control instruction issued by the TSP platform, EVTBOX first performs information verification with the VCU, and after the verification is passed, it sends the instruction issued by the TSP platform to the VCU; the vehicle controller forwards the control instruction to the body controller (BCM), air conditioning controller (ACCM) and other low-voltage automotive electrical systems; the low-voltage automotive electrical system is responsible for collecting various sensor data and CAN data and executing the corresponding instructions of the platform, and feedback the execution results to EVTBOX in the form of CAN signals; EVTBOX collects information from the vehicle CAN bus and feeds back the execution results to the TSP platform; the TSP platform feeds back the current execution status of the vehicle to the mobile phone APP so that the user can view the current vehicle status.

[0041] After the mobile APP user downloads the APP through the QR code or the company's official mall platform, he enters the APP login interface, enters the ID number, mobile phone number, car license plate number, vehicle VIN number, and sets the login password to complete the registration and complete the binding of the vehicle and the user. The binding information will be transmitted to the TSP platform via the Internet. The platform records and saves the information to provide technical support for the next step of human-computer interaction information verification; when using it, enter the login password, enter the APP program after verification by the TSP platform, and execute user instructions.

[0042] like Figure 3As shown, the remote control security authentication is as follows: EVTBOX sends a remote control request message without a key to VCU. After receiving the remote control message without a key sent by EVTBOX, VCU resets the seed and sends a remote control verification message to EVTBOX. After EVTBOX calculates the key based on the seed according to the remote control verification message sent by VCU, it sends a remote control request message with a key to VCU. After receiving the remote control request message with a key, VCU verifies whether the key is correct. If the key is correct, VCU sends a remote control verification success message to EVTBOX; if the key is incorrect, VCU sends a remote control verification failure message to EVTBOX; when EVTBOX receives the remote control verification success signal, the remote control security authentication process passes; when EVTBOX receives the remote control verification failure signal, the process jumps to the initial state and re-checks. After two verification failures, the remote control security authentication process fails; if the verification time exceeds 1 minute, it is considered that the verification has failed and the remote control security authentication fails.

[0043] After binding user and vehicle information, the client registers an account. After the password is verified, the client can operate the corresponding function on the UI through the mobile app. The operation command is transmitted to the TSP platform via the 4G / 5G network. The EVTBOX monitors the current vehicle status information and uploads it to the TSP platform via the SIM card. The TSP platform records and saves the last data before the EVTBOX goes into sleep in real time. The TSP platform determines whether the remote control conditions are met based on the data before the EVTBOX goes into sleep. When the TSP platform receives that the vehicle is in the doors closed, windows closed, engine off, not charging, and parking brake applied state, it sends a remote control request to the EVTBOX on the vehicle. The EVTBOX and the VCU perform remote control security authentication. The VCU sends the user's current control request to the vehicle electrical system in the form of a CAN signal. After the vehicle electrical system executes the command action, it sends the execution result to the bus in the form of a CAN signal. The EVTBOX detects the bus status signal, determines the remote control execution result, and feedbacks it to the TSP platform. Finally, the TSP platform feedbacks the remote control execution result to the app, forming a closed loop.

[0044] Before the EVTBOX and VCU perform remote control security authentication, the VCU needs to be awakened. Specifically, the EVTBOX and VCU establish an OSEK network ring and wake up the VCU through a CAN signal. When the EVTBOX receives the network management signal from the VCU and the Alive indicator bit is activated, the VCU is considered to be awakened.

[0045] The user commands include remote control commands and remote monitoring commands; the remote control commands include remote door unlocking, remote window lifting, remote vehicle starting, remote vehicle search control, remote air conditioning control, remote electric heating control, remote charging control, car anti-theft control, etc.; the remote monitoring commands include real-time vehicle positioning, real-time display of vehicle status information (including the battery pack's SOC value, temperature, whether the air conditioning is turned on, and the door opening status), historical trajectory playback, energy consumption prompts, and fault alarm reminder functions.

[0046] Remote door unlocking: The user issues a command on the mobile app. This command transmits the data to the TSP platform via the 5G base station and server. The TSP platform processes the data and transmits it to the EVTBOX via the 5G base station. The EVTBOX performs remote control security authentication with the VCU and sends it to the CAN bus. The BCM receives and decodes the data, which controls the door lock motor to reverse, unlocking the door. The door lock sensor feeds back the current status signal to the BCM, which converts it into binary data and sends it to the CAN bus. The EVTBOX transmits the received data to the TSP platform via network signals, and the TSP platform transmits it to the customer's mobile app via 5G network signals.

[0047] Remote window lifting: Users issue commands on their mobile app, including those for the driver's side window lift switch to shift up, down, or both. These commands are transmitted to the TSP platform via the 5G base station and server. The TSP platform processes the data and transmits it to the EVTBOX via the 5G base station. The EVTBOX performs remote control security authentication with the VCU and sends the data to the CAN bus. The data is then received and decoded by the DCM (Door Control Module), which controls the motor in the window lift to rotate forward or reverse to achieve automatic window lifting. The lift's built-in displacement sensor feeds back the current status signal to the DCM, which converts it into binary data and sends it to the CAN bus. EVTBOX transmits the received data to the TSP platform via network signals, and the TSP platform transmits the data to the customer's mobile app via 5G network signals.

[0048] like Figure 4As shown, to remotely start a vehicle, the user issues a one-touch start command on a mobile app. This command is transmitted to the TSP platform via a 5G base station. The TSP platform processes the command and passes it to the EVTBOX via the 5G base station using the HTTPS protocol. The EVTBOX establishes an OSEK network loop with the VCU and wakes up the VCU via a CAN signal. When the EVTBOX receives the VCU's network management signal and the Alive indicator is active, it considers the VCU awake. Within 30 seconds, the VCU controls the ACC and ON relays to ensure the normal operation of all low-voltage electrical components in the vehicle. Simultaneously, the EVTBOX and the VCU perform remote control security authentication and send the command to the CAN bus. The VCU determines whether the vehicle meets the high-voltage conditions. If so, it closes the BMS main and negative relays and sends a power-on command to the ICU (all-in-one intelligent control unit). After powering on, the VCU sends a "Ready" signal to the bus. Upon detecting the Ready signal, the EVTBOX reports the current execution status to the TSP platform, which is then transmitted to the mobile app for display. During a remote start, if a driver command is received, remote control execution is terminated. When executing the remote vehicle search action, if the current user sends other control commands, in order to ensure the frequent start and stop of the vehicle's high-voltage system, the remote start command will continue to be executed, and then the current remote control command will be executed.

[0049] Remote Vehicle Search and Control: The user issues a one-touch vehicle start command via the mobile app. This command is transmitted to the TSP platform via a 5G base station. The TSP platform processes the command and transmits it to the EVTBOX via the 5G base station using the HTTPS protocol. The EVTBOX establishes an OSEK network link with the VCU and wakes up the VCU via a CAN signal. When the EVTBOX receives the VCU's network management signal and the Alive indicator is active, the VCU is considered awake. The EVTBOX and VCU perform remote control security authentication and send the command to the CAN bus. The VCU forwards the current operation command to the BCM, which activates the hazard lights and horn relay to implement the audible and visual alarm functions. The BCM sends the execution result via CAN signals, which are then transmitted to the mobile app for display. While remote vehicle search is in progress, if the BCM receives any new remote body control command, it terminates the ongoing remote vehicle search and executes the new remote control command. If the BCM receives a local hazard warning or horn control signal during remote vehicle search, it terminates the ongoing remote vehicle search and executes the new remote control command.

[0050] Remote air conditioning control: The user issues a command to turn on the air conditioning on the mobile phone APP. The command transmits the data to the TSP platform through the 5G base station. After processing, the TSP platform transmits it to the vehicle-end EVTBOX through the 5G base station according to the HTTPS protocol. The EVTBOX and VCU establish an OSEK network loop and wake up the VCU through the CAN signal. When the EVTBOX receives the network management signal of the VCU and the Alive indicator bit is activated, it is considered that the VCU has been awakened. At the same time, the EVTBOX and VCU perform remote control security authentication operations and send them to the CAN bus. The VCU first controls the high voltage of the entire vehicle. After the high voltage is completed, the VCU forwards the current operation command to the ACCM. The ACCM controls the operation of the air conditioning compressor and the VCU controls the operation of the air conditioning compressor cooling fan. Then, the ACCM and VCU send the current controller execution status in the form of a CAN signal, which is then transmitted step by step to the mobile phone APP for display.

[0051] Remote air conditioning control: The air conditioning can be manually shut off and timed off. Based on remote air conditioning control, the user issues a timer duration command, which is converted into information by the TSP platform, EVTBOX, VCU and other systems and finally sent to the ACCM in the form of a CAN signal. The ACCM starts timing from the moment it receives the control command. After the user-set duration is reached, the AC compressor is disconnected and the feedback is sent to the CAN bus. When the VCU receives the air conditioning function shutdown and there are no current operation instructions, the VCU delays for 60 seconds, stops the enable control of the ACC and the ON gear relay, and powers down the entire vehicle. If a local user operation instruction or a remote air conditioning shutdown instruction is received during this process, the vehicle exits the timer mode and enters the normal mode.

[0052] Remote charging control: When the charging gun is normally connected, the user issues a charging command on the mobile phone APP. The command transmits the data to the TSP platform through the 5G base station. After processing, the TSP platform passes it to the EVTBOX through the 5G base station according to the HTTPS protocol. The EVTBOX and the VCU establish an OSEK network loop and wake up the VCU through the CAN signal. When the EVTBOX receives the network management signal of the VCU and the Alive indicator bit is activated, it is considered that the VCU has been awakened. At the same time, the EVTBOX and the VCU perform remote control security authentication operations and send them to the CAN bus. The VCU forwards the current operation command to the BMS and ICU. After receiving the charging command, the BMS determines whether the charging conditions are met. If it is determined that the charging conditions are met, it sends the current fast charging contactor closing command to the ICU and feeds back the execution status to the BMS in the form of a CAN signal. At this time, the charging action starts. The BMS sends the charging status command in the form of a CAN signal, which is then transmitted step by step to the mobile phone APP for display.

[0053] The remote charging control includes power battery charging. The power battery charging requires the charging gun to be in normal state. The user sends a pre-charging time instruction on the mobile phone APP. After receiving it, the TSP platform determines whether the current time is consistent with the scheduled time. If not, the charging instruction is not sent to the EVTBOX, and the vehicle network and controller are kept in a dormant state; if they are consistent, the control instruction is sent to the vehicle EVTBOX, and the EVTBOX forwards the control instruction to the VCU. The VCU wakes up the BMS and ICU through hard wire or network. At the same time, the VCU determines whether the current vehicle status information meets the charging conditions. If so, it sends a charging instruction to the BMS and ICU. The BMS and ICU control their own controller contactors to close and execute charging and feedback the execution status. The VCU forwards the status to the EVTBOX through the CAN network. The EVTBOX and TSP platform feedback the execution status to the mobile phone APP, and the mobile phone APP displays the current charging status.

[0054] The remote charging control also includes low-voltage battery charging. The EVTBOX has a timed wake-up function. The TSP platform can regularly detect the current battery voltage information and upload the monitoring information to the mobile phone APP. The user can set the low battery voltage reminder threshold on the mobile phone APP. When the TSP platform detects that the current battery voltage is lower than the user-set low battery voltage reminder threshold, a pop-up window will remind the user whether the current battery voltage is too low and recharging is required. The user decides whether to execute the low-voltage battery recharging function based on the user's request. If the low-voltage battery recharging function is selected, the TSP platform will send a command to the EVTBOX on the vehicle side. The EVTBOX and the VCU will perform a safety information verification. After the verification is passed, the VCU will wake up the ICU and BMS and control the DCDC to recharge the battery. At the same time, the TSP platform will detect the current battery voltage in real time and determine whether to stop recharging. If the conditions are met, the stop recharging command will be issued. The VCU will forward the recharging status to the EVTBOX via the CAN network. The EVTBOX and the TSP platform will feedback the execution status to the mobile phone APP, and the mobile phone APP will display the current charging status.

[0055] Real-time vehicle positioning: The GPS antenna and SIM card configured by EVTBOX are used to locate the current vehicle location information, and the positioning information is transmitted to the mobile phone APP via the TSP platform via the Internet to inform the user of the current vehicle location information.

[0056] Real-time vehicle status information: EVTBOX obtains the current vehicle status information from each controller or VCU through the CAN network and transmits it to the TSP platform in real time. The TSP platform transmits it to the mobile phone APP via the Internet to inform the user of the current vehicle information.

[0057] Historical trajectory playback: While real-time vehicle positioning, the TSP platform will record and save the current location information in real time. The path of a specific time period can be viewed through data playback.

[0058] Historical fault query: EVTBOX uploads vehicle fault information to the TSP platform and mobile app in real time, allowing OEMs to understand current vehicle operating data and conduct timely analysis and processing.

[0059] This invention leverages the internet of big data, a remote monitoring platform, and an onboard terminal to provide timely access to vehicle-related information and facilitate user monitoring and control of vehicle information using a mobile app. This invention integrates multiple remote control and monitoring functions, enabling remote control of various vehicle functions through a mobile app. It also provides real-time monitoring and remote fault diagnosis and early warning, allowing drivers to quickly identify safety hazards and promptly troubleshoot, ensuring driving safety.

[0060] Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.

7. The remote intelligent control method for a new energy truck according to claim 6, characterized in that: The remote charging control includes power battery charging. The power battery charging requires the charging gun to be in normal state. The user sends a pre-charging time instruction on the mobile phone APP. After receiving it, the TSP platform determines whether the current time is consistent with the scheduled time. If not, the charging instruction is not sent to the EVTBOX, and the vehicle network and controller are kept in a dormant state; if they are consistent, the control instruction is sent to the vehicle EVTBOX, and the EVTBOX forwards the control instruction to the VCU. The VCU wakes up the BMS and ICU through hard wire or network. At the same time, the VCU determines whether the current vehicle status information meets the charging conditions. If so, it sends a charging instruction to the BMS and ICU. The BMS and ICU control their own controller contactors to close and execute charging and feedback the execution status. The VCU forwards the status to the EVTBOX through the CAN network. The EVTBOX and TSP platform feedback the execution status to the mobile phone APP, and the mobile phone APP displays the current charging status.

8. The remote intelligent control method for new energy trucks according to claim 6 is characterized by: The remote charging control also includes low-voltage battery charging. The EVTBOX has a timed wake-up function. The TSP platform can regularly detect the current battery voltage information and upload the monitoring information to the mobile phone APP. The user can set the low battery voltage reminder threshold on the mobile phone APP. When the TSP platform detects that the current battery voltage is lower than the user-set low battery voltage reminder threshold, a pop-up window will remind the user whether the current battery voltage is too low and recharging is required. The user decides whether to execute the low-voltage battery recharging function based on the user's request. If the low-voltage battery recharging function is selected, the TSP platform will send a command to the EVTBOX on the vehicle side. The EVTBOX and the VCU will perform a safety information verification. After the verification is passed, the VCU will wake up the ICU and BMS and control the DCDC to recharge the battery. At the same time, the TSP platform will detect the current battery voltage in real time and determine whether to stop recharging. If the conditions are met, the stop recharging command will be issued. The VCU will forward the recharging status to the EVTBOX via the CAN network. The EVTBOX and the TSP platform will feedback the execution status to the mobile phone APP, and the mobile phone APP will display the current charging status.

9. The remote intelligent control method for new energy trucks according to claim 6, characterized in that: Real-time vehicle positioning uses the GPS antenna and SIM card configured on the EVTBOX platform to locate the current vehicle location. This information is then transmitted to the mobile app via the TSP platform via the internet, informing the user of the current vehicle location. Historical trajectory playback, while simultaneously with real-time vehicle positioning, also records and saves the current location information on the TSP platform. Data playback allows users to review the path taken during a specific time period.

10. A remote intelligent control system for new energy trucks, characterized by: include: A client, configured to send user instructions; The TSP platform is used to receive requests corresponding to user instructions sent by the client and send them to EVTBOX; EVTBOX, which is used to receive requests from the TSP platform, wake up the VCU, and perform remote control security authentication with the VCU; VCU, the VCU is used to forward control instructions to various controllers of the vehicle electrical system; The automobile electrical system executes the action corresponding to the control instruction. After executing the instruction action, the automobile electrical system sends the execution result to the bus in the form of a CAN signal. The EVTBOX detects the bus status signal to determine the remote control execution result and feeds it back to the TSP platform. The TSP platform feeds back the remote control execution result to the client.
