Description

Technical Field

[0001] This invention relates to a remote intelligent control system and method for new energy trucks, and pertains to the field of intelligent control technology for new energy vehicles. Background Technology

[0002] With the development of intelligent and connected vehicles, the demand for remote monitoring and control of vehicles via the internet is increasing. The rapid promotion of new energy vehicles has driven the booming development of various car rental models. For effective supervision, remote data monitoring and vehicle locking functions are particularly necessary. Furthermore, current technology for remote vehicle control can only achieve single functions such as raising and lowering windows and one-button start; multiple functions cannot be integrated into a single device, and the remote control capabilities are far from meeting the current demand for multi-functional remote vehicle control. Moreover, current technology lacks real-time monitoring and remote fault diagnosis and early warning functions for vehicles and equipment, making it difficult for drivers to quickly identify safety hazards and promptly resolve faults. Summary of the Invention

[0003] To address the aforementioned technical problems, the present invention aims to provide a remote intelligent control system and method for new energy trucks, the specific technical solution of which is as follows:

[0004] A remote intelligent control method for new energy trucks involves a client sending a remote control request to a TSP platform. The TSP platform receives the request and sends it to the EVTBOX on the vehicle side. The EVTBOX performs remote control security authentication with the VCU. The VCU sends control commands to the vehicle's electrical system, which then executes power control. The vehicle's electrical system executes body control. After completing the command actions, the vehicle's electrical system sends the execution results to the bus in the form of CAN signals. The EVTBOX detects the bus status signals 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.

[0005] Preferably, the client is a mobile APP. The TSP platform connects to the client and EVTBOX via base station and 5G signal wireless communication. After downloading the APP through a QR code or the company's official online store, the mobile APP user enters the APP login interface, enters their ID card number, mobile phone number, vehicle license plate number, and vehicle VIN number, and sets a login password to complete the registration. When using the APP, the user enters the login password, and after verification by the TSP platform, enters the APP program to execute user commands.

[0006] Preferably, 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 from EVTBOX, VCU resets the seed and sends a remote control verification message to EVTBOX. EVTBOX calculates the key based on the seed after receiving the remote control verification message from VCU, and then sends a remote control request message with the key to VCU. After receiving the remote control request message with the 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 is successful. When EVTBOX receives the remote control verification failure signal, the process jumps to the initial state and re-verifies. If two verifications fail, the remote control security authentication process fails. If the verification time exceeds 1 minute, the verification is considered 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 at the vehicle end, 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 of the EVTBOX before it goes into sleep mode. The TSP platform determines whether the remote control conditions are met based on the data of the EVTBOX before it goes into sleep mode. When the TSP platform receives the data that the current vehicle is in the following states simultaneously: the doors are closed, the windows are closed, the vehicle is off, the vehicle is not charging, and the handbrake is engaged, the platform sends the remote control request to the EVTBOX at the vehicle end.

[0008] Preferably, before the EVTBOX performs remote control security authentication with the VCU, the VCU needs to be woken up. Specifically, the EVTBOX and VCU establish an OSEK network loop 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, it is considered that the VCU has been woken up.

[0009] Furthermore, the user instructions include remote control instructions and remote monitoring instructions; the remote control instructions include remote door lock unlocking, remote window raising / lowering, remote vehicle start, remote vehicle location control, remote air conditioning control, remote electric heating control, remote charging control, and vehicle anti-theft control; the remote monitoring instructions include real-time vehicle positioning, real-time display of vehicle status information, historical trajectory playback, energy consumption reminders, and fault alarm reminders.

[0010] Furthermore, the remote charging control includes charging the power battery. Charging the power battery requires the charging gun to be in a normal plug-in state. The user sends a pre-charging time command via a mobile app. Upon receiving the command, the TSP platform determines whether the current time matches the scheduled time. If they do not match, no charging command is sent to the EVTBOX, and the vehicle network and controller remain in sleep mode. If they match, the control command is sent to the vehicle's EVTBOX, which forwards it to the VCU. The VCU wakes up the BMS and ICU via hardwire or network. Simultaneously, the VCU determines whether the current vehicle status meets the charging conditions. If so, it sends a charging command to the BMS and ICU. The BMS and ICU control their own controller contactors to close, executing the charging process and providing feedback on the execution status. The VCU forwards this status to the EVTBOX via the CAN network. The EVTBOX and TSP platform then feed back the execution status to the mobile app, which 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 periodically detect the current battery voltage information and upload the monitoring information to the mobile APP. Users can set a low battery voltage reminder threshold in the mobile 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 reminds the user whether the current battery voltage is too low and whether to start the low-voltage battery charging function. The user decides whether to execute the low-voltage battery charging function according to their needs. If the low-voltage battery charging function is selected to be activated, the TSP platform sends a command to the EVTBOX at the vehicle end. The EVTBOX and VCU perform safety information verification. After the verification is successful, the VCU wakes up the ICU and BMS and controls the DCDC to work to charge the battery. At the same time, the TSP platform detects the current battery voltage in real time and determines whether to stop charging. If the conditions are met, a stop charging command is issued. The VCU forwards the charging status to the EVTBOX through the CAN network. The EVTBOX and TSP platform feed back the execution status to the mobile APP, which displays the current charging status.

[0012] Furthermore, the real-time vehicle positioning uses the GPS antenna and SIM card configured on the EVTBOX platform to locate the current vehicle position information, and transmits this positioning information to a mobile app via the internet through the TSP platform, informing the user of the current vehicle location. During the historical trajectory playback, while the real-time vehicle positioning is being performed, the TSP platform records and saves the current location information in real time, allowing users to review paths taken during specific time periods through data playback.

[0013] A remote intelligent control system for new energy trucks includes:

[0014] A client, used to send user commands;

[0015] The TSP platform is used to receive requests corresponding to user commands sent by clients and send them to EVTBOX.

[0016] EVTBOX, which is used to receive requests sent by the TSP platform, and at the same time wake up the VCU and perform remote control security authentication with the VCU;

[0017] VCU, which is used to forward control commands to the controllers of the vehicle's electrical system;

[0018] The automotive electrical system executes actions corresponding to control commands. After completing the command actions, the automotive electrical system sends the execution results to the bus in the form of CAN signals. The EVTBOX detects the bus status signals to determine the remote control execution results and feeds them back to the TSP platform. The TSP platform then feeds back the remote control execution results to the client.

[0019] This invention, based on big data, the internet, a remote monitoring platform, and an in-vehicle terminal, enables timely access to vehicle-related information and allows users to conveniently monitor and control vehicle information via a mobile app. Integrating multiple remote control and monitoring functions, this invention allows for remote control of various vehicle functions via a mobile app, as well as real-time monitoring and remote fault diagnosis and early warning. Drivers can quickly identify safety hazards, promptly resolve faults, and ensure driving safety. Attached Figure Description

[0027] EVTBOX: Remote monitoring terminal

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

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

[0034] A client, used to send user commands;

[0035] The TSP platform is used to receive requests corresponding to user commands sent by clients and send them to EVTBOX.

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

[0037] VCU, which is used to forward control commands to the controllers of the vehicle's electrical system;

[0038] The automotive electrical system executes actions corresponding to control commands. After completing the command actions, the automotive electrical system sends the execution results to the bus in the form of CAN signals. The EVTBOX detects the bus status signals to determine the remote control execution results and feeds them back to the TSP platform. The TSP platform then feeds back the remote control execution results to the client.

[0039] like Figure 2 As shown, a remote intelligent control method for new energy trucks involves a client sending a remote control request to a TSP platform. The TSP platform receives the request and sends it to the EVTBOX in the vehicle. The EVTBOX performs remote control security authentication with the VCU (Vehicle Control Unit). The VCU then sends control commands to the vehicle's electrical system, which executes power control. The vehicle's electrical system executes body control, and after completing the command actions, it sends the execution results to the bus in the form of a CAN signal. The EVTBOX detects the bus status signals 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 all types of new energy vehicle models and enables users to remotely operate and monitor the vehicle.

[0040] The client is a mobile app, responsible for human-computer interaction. Users select the command to be executed and confirm it through the app. The TSP platform connects to the client and EVTBOX via base station and 5G wireless communication, receiving operation commands from the mobile app. The TSP platform server receives the control command and transmits it to the EVTBOX via 5G. After receiving the control command from the TSP platform, the EVTBOX first verifies the information with the VCU. If the verification is successful, it sends the command from the TSP platform to the VCU. The vehicle controller forwards the control command to the body control module (BCM), air conditioning controller (ACCM), and other low-voltage automotive electrical systems. The low-voltage automotive electrical systems collect various sensor data and CAN data, execute the corresponding commands from the platform, and send the execution results back to the EVTBOX in the form of CAN signals. The EVTBOX collects information from the vehicle's CAN bus and sends the execution results back to the TSP platform. The TSP platform then sends the current vehicle status back to the mobile app so that users can view the current vehicle status.

[0041] After downloading the mobile app via QR code or the company's official online store, users enter the app login interface, input their ID card number, mobile phone number, vehicle license plate number, and vehicle VIN number, and set a login password to complete registration and bind the vehicle to the user. This binding information is transmitted to the TSP platform via the internet, where it is recorded and saved to provide technical support for the next step of human-computer interaction information verification. When using the app, users enter their login password, and after successful verification by the TSP platform, they enter the app program and execute user commands.

[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 from EVTBOX, VCU resets the seed and sends a remote control verification message to EVTBOX. EVTBOX calculates the key based on the seed after receiving the remote control verification message from VCU, and then sends a remote control request message with the key to VCU. After receiving the remote control request message with the 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 is successful. When EVTBOX receives the remote control verification failure signal, the process jumps to the initial state and re-verifies. After two failed verifications, the remote control security authentication process fails. If the verification time exceeds 1 minute, the verification is considered failed, and the remote control security authentication fails.

[0043] After registering an account by binding user and vehicle information on the client side, and after successful password verification, users can operate the corresponding functions of the UI interface through a mobile APP. This operation command is transmitted to the TSP platform via 4G / 5G network. The EVTBOX monitors the current vehicle status information and uploads it to the TSP platform via SIM card. The TSP platform records and saves the last data of the EVTBOX before it goes into sleep mode. The TSP platform determines whether the current remote control conditions are met based on the data of the EVTBOX before it goes into sleep mode. When the TSP platform receives a message that the current vehicle is in a state where the doors are closed, the windows are closed, the vehicle is off, the vehicle is not charging, and the handbrake is engaged, the platform sends a remote control request to the EVTBOX at the vehicle end. The EVTBOX and VCU perform remote control security authentication. The VCU sends the user's current control request to the automotive electrical system in the form of a CAN signal. After the automotive 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. Finally, the TSP platform feeds back 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 woken up. Specifically, the EVTBOX and VCU establish an OSEK network loop 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, it is considered that the VCU has been woken up.

[0045] The user commands include remote control commands and remote monitoring commands; the remote control commands include remote door lock unlocking, remote window raising / lowering, remote vehicle start, remote vehicle location control, remote air conditioning control, remote electric heating control, remote charging control, and vehicle anti-theft control; the remote monitoring commands include real-time vehicle positioning, real-time display of vehicle status information (including battery pack SOC value, temperature, whether the air conditioning is on, and door opening status), historical trajectory playback, energy consumption reminders, and fault alarm reminders.

[0046] Remote door unlocking: The user issues a command via a mobile app. This command is transmitted to the TSP platform via a 5G base station and server. The TSP platform processes the command and transmits it to the EVTBOX via the 5G base station. The EVTBOX performs remote control security authentication calculations with the VCU and then sends the data to the CAN bus. The BCM receives and decodes the data, controlling the door lock motor to reverse and unlock 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 operation: Users issue commands via a mobile app, including commands to raise or lower the driver's side window, passenger side window, etc. These commands are transmitted to the TSP platform via a 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 then sends the data to the CAN bus. The DCM (Door Control Module) receives and decodes the data, controlling the built-in motor of the window regulator to rotate forward or backward to achieve automatic window raising and lowering. The built-in displacement sensor in the window regulator feeds back the current status signal to the DCM, which converts it into binary data and sends it to the CAN bus. The EVTBOX then transmits the received data to the TSP platform via network signal, and the TSP platform transmits it to the user's mobile app via 5G network signal.

[0048] like Figure 4As shown, remote vehicle start: The user issues a one-button start command via a mobile app. This command transmits data to the TSP platform via a 5G base station. After processing, the TSP platform transmits the data to the EVTBOX via the 5G base station according to 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 network management signal from the VCU and the Alive indicator is activated, it considers the VCU to be awakened. After being awakened, the VCU controls the ACC and ON relays to engage within 30 seconds, ensuring that all low-voltage electrical components in the vehicle can operate normally. Simultaneously, the EVTBOX and VCU perform remote control safety authentication calculations and send the results to the CAN bus. The VCU determines whether the vehicle meets the high-voltage conditions. If it does, it controls the BMS main negative relay to close and sends a power-on command to the ICU (Multi-functional Intelligent Control Unit). After power-on, the vehicle status is sent to the outside of the bus as Ready. The EVTBOX detects the Ready signal and reports the current execution status to the TSP platform, which then transmits the information to the mobile app for display. If a driver's operation command is received during the remote start operation, the remote control execution is terminated. When performing a remote vehicle locator action, if the current user issues other control commands, the remote start command will continue to be executed to ensure the frequent start and stop of the vehicle's high-voltage system, and then the current remote control command will be executed.

[0049] Remote vehicle location control: The user issues a one-button start command to the vehicle via a mobile app. This command transmits data to the TSP platform via a 5G base station. After processing, the TSP platform transmits the data to the EVTBOX via the 5G base station according to 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 network management signal from the VCU and the Alive indicator is activated, it considers the VCU to be awake. Simultaneously, the EVTBOX and VCU perform remote control security authentication calculations and send the results to the CAN bus. The VCU forwards the current operation command to the BCM. The BCM controls the hazard lights and horn relays to activate the audible and visual alarm function and transmits the execution results externally in the form of CAN signals, which are then relayed to the mobile app for display. During remote vehicle location, if the current BCM receives any new remote vehicle control command, the ongoing remote vehicle location operation is terminated, and the new remote control command is executed. Similarly, if the current BCM receives a local hazard alarm or horn control signal during remote vehicle location, the ongoing remote vehicle location operation is terminated, and the new remote control command is executed.

[0050] Remote air conditioning control: The user issues a command to turn on the air conditioning via a mobile app. This command transmits data to the TSP platform via a 5G base station. After processing, the TSP platform transmits the data to the EVTBOX in the vehicle via the 5G base station according to the HTTPS protocol. The EVTBOX and VCU establish an OSEK network loop and wake up the VCU via a CAN signal. When the EVTBOX receives the network management signal from the VCU and the Alive indicator is activated, it considers the VCU to be awake. At the same time, the EVTBOX and VCU perform remote control security authentication calculations and send the results to the CAN bus. The VCU first controls the vehicle to apply high voltage. After the high voltage is applied, the VCU forwards the current operation command to the ACCM. The ACCM controls the air conditioning compressor to work, and the VCU controls the air conditioning compressor cooling fan to work. Then, the ACCM and VCU transmit the current controller execution status in the form of CAN signals, which are then transmitted to the mobile app for display.

[0051] Remote Air Conditioning Control: The system includes manual and timed shutdown functions for the air conditioning. Based on remote air conditioning control, the user issues a timed shutdown command. This command is converted into a CAN signal by the TSP platform, EVTBOX, and VCU, and then sent to the ACCM. The ACCM starts timing upon receiving the control command and continues until the user-set time is reached. At this point, the ACCM deactivates the air conditioning compressor and sends feedback to the CAN bus. When the VCU receives a message indicating the air conditioning is off and there are no current operation commands, the VCU delays for 60 seconds, stops enabling the ACC and ON relays, and powers off the vehicle. If a local user operation command or a remote air conditioning shutdown command is received during this process, the system exits the timed mode and enters normal mode.

[0052] Remote charging control: When the charging gun is normally connected, the user issues a charging command via the mobile app. This command is transmitted to the TSP platform via the 5G base station. After processing, the TSP platform transmits the data to the EVTBOX via the 5G base station according to the HTTPS protocol. The EVTBOX and VCU establish an OSEK network loop and wake up the VCU via a CAN signal. When the EVTBOX receives the network management signal from the VCU and the Alive indicator is activated, it considers the VCU to be awake. At the same time, the EVTBOX and VCU perform remote control security authentication calculations and send the results 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 the 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 begins. The BMS sends the charging status command out in the form of a CAN signal and then transmits it to the mobile app for display.

[0053] The remote charging control includes charging the power battery. Charging the power battery requires the charging gun to be in a normal plug-in state. The user sends a pre-charging time command via a mobile app. Upon receiving the command, the TSP platform determines if the current time matches the scheduled time. If they do not match, no charging command is sent to the EVTBOX, and the vehicle network and controller remain in sleep mode. If they match, the control command is sent to the EVTBOX, which forwards it to the VCU. The VCU wakes up the BMS and ICU via hardwire or network. Simultaneously, the VCU determines if the current vehicle status meets the charging conditions. If so, it sends a charging command to the BMS and ICU. The BMS and ICU control their own controller contactors to close, executing the charging process and providing feedback on the execution status. The VCU forwards this status to the EVTBOX via the CAN network. The EVTBOX and TSP platform then feed the execution status back to the mobile app, which 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 periodically detect the current battery voltage information and upload the monitoring information to the mobile APP. Users can set a low battery voltage reminder threshold in the mobile 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 reminds the user whether the current battery voltage is too low and whether to start the low-voltage battery charging function. The user decides whether to execute the low-voltage battery charging function according to their needs. If the low-voltage battery charging function is selected, the TSP platform sends a command to the EVTBOX at the vehicle end. The EVTBOX and VCU perform safety information verification. After the verification is successful, the VCU wakes up the ICU and BMS and controls the DCDC to work to charge the battery. At the same time, the TSP platform detects the current battery voltage in real time and determines whether to stop charging. If the conditions are met, a stop charging command is issued. The VCU forwards the charging status to the EVTBOX through the CAN network. The EVTBOX and TSP platform feed back the execution status to the mobile APP, which displays the current charging status.

[0055] Real-time vehicle location: The EVTBOX uses a GPS antenna and SIM card to locate the current vehicle position and transmits this location information to a mobile app via the TSP platform, informing the user of the vehicle's current location.

[0056] Real-time vehicle status information: EVTBOX obtains the current vehicle status information sent by each controller or VCU through the CAN network and transmits it to the TSP platform in real time. The TSP platform then uses the Internet to transmit the information to the mobile APP, informing the user of the current vehicle status.

[0057] Historical trajectory playback: While locating the vehicle in real time, the TSP platform records and saves the current location information in real time. By playing back the data, the path for a specific time period can be viewed.

[0058] Historical fault query: Vehicle fault information is uploaded to the TSP platform and mobile APP in real time through EVTBOX, which makes it easier for OEMs to understand the current vehicle operation data and analyze and deal with it in a timely manner.

[0059] This invention, based on big data, the internet, a remote monitoring platform, and an in-vehicle terminal, enables timely access to vehicle-related information and allows users to conveniently monitor and control vehicle information via a mobile app. Integrating multiple remote control and monitoring functions, this invention allows for remote control of various vehicle functions via a mobile app, as well as real-time monitoring and remote fault diagnosis and early warning. Drivers can quickly identify safety hazards, promptly resolve faults, and ensure driving safety.

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

After downloading the APP through a QR code or the company's official online store, the mobile APP user enters the APP login interface, enters their ID card number, mobile phone number, vehicle license plate number, and vehicle VIN number, and sets a login password to complete the registration. When using the APP, the user enters the login password, and after verification by the TSP platform, enters the APP program to execute user commands.

3. The remote intelligent control method for a new energy truck according to claim 1, characterized in that: 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 from EVTBOX, VCU resets the seed and sends a remote control verification message to EVTBOX. EVTBOX calculates the key based on the seed after receiving the remote control verification message sent by VCU, and then sends a remote control request message with the key to VCU. After receiving the remote control request message with the 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, the VCU sends a remote control verification failure message to the EVTBOX; when the EVTBOX receives a remote control verification success signal, the remote control security authentication process is successful; when the EVTBOX receives a remote control verification failure signal, the process jumps to the initial state and re-verifies. If the verification fails twice, the remote control security authentication process is not successful. If the verification time exceeds 1 minute, the verification is considered to have failed and the remote control security authentication will not pass.

4. The remote intelligent control method for a new energy truck according to claim 1, characterized in that: Before the EVTBOX and VCU perform remote control security authentication, the VCU needs to be woken up. Specifically, the EVTBOX and VCU establish an OSEK network loop 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, it is considered that the VCU has been woken up.

5. The remote intelligent control method for a new energy truck according to claim 2, characterized in that: The remote monitoring commands include real-time vehicle positioning, real-time display of vehicle status information, historical trajectory playback, energy consumption alerts, and fault alarm reminders.

6. The remote intelligent control method for a new energy truck according to claim 5, characterized in that: The real-time vehicle positioning uses the GPS antenna and SIM card configured on the EVTBOX platform to locate the current vehicle location information, and transmits the current vehicle location information to the mobile APP via the Internet through the TSP platform to inform the user of the current vehicle location information; the historical trajectory playback, while the real-time vehicle positioning is being performed, the TSP platform records and saves the current location information in real time, and the path for a specific time period can be viewed through data playback.

7. A remote intelligent control system for new energy trucks, characterized in that: The method for implementing the remote intelligent control of new energy trucks as described in claim 1 includes: A client, used to send user commands; The TSP platform is used to receive requests corresponding to user commands sent by clients and send them to EVTBOX. EVTBOX, which is used to receive requests sent by the TSP platform, and at the same time wake up the VCU and perform remote control security authentication with the VCU; VCU, which is used to forward control commands to the controllers of the vehicle's electrical system; The automotive electrical system executes actions corresponding to control commands. After completing the command actions, the automotive electrical system sends the execution results to the bus in the form of CAN signals. The EVTBOX detects the bus status signals to determine the remote control execution results and feeds them back to the TSP platform. The TSP platform then feeds back the remote control execution results to the client.
