[0017] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0018] In view of the problems in the prior art, the embodiment of the present application provides an intelligent power distribution method for unmanned cargo vehicles, which can be applied to a power distribution device. The power distribution device is suitable for unified management and control of a large number of unmanned cargo vehicles, specifically including: Figure 1 The remote control platform and the on-board control unit of the cargo-carrying unmanned vehicle shown. The remote control platform can be used to monitor and manage the working status, operating parameters and positions of multiple cargo-carrying unmanned vehicles in real time, and can send control instructions to the vehicles as needed to perform operations such as power-on, shutdown or parameter adjustment. The on-board control unit is used to receive instructions sent by the remote control platform and perform corresponding power-on operations when the instructions are authorized or specific conditions are met. The on-board control unit can also collect the vehicle's operating data and feed it back to the remote control platform through the communication network, so that the remote control platform can grasp the vehicle's status and working environment in real time, thereby realizing intelligent remote management and control of cargo-carrying unmanned vehicles.

[0019] The intelligent power distribution method for the unmanned cargo vehicle disclosed in this application can be as follows: Figure 2 As shown, the following steps are included:

[0004] Step 201: The remote control platform responds to the vehicle start command and sends a remote start message to the vehicle control unit.

[0020] In implementation, the manager of the unmanned cargo vehicle can remotely control a certain unmanned cargo vehicle to perform power-on processing through the remote control platform according to actual needs. Specifically, the manager can input a vehicle start command corresponding to a certain unmanned cargo vehicle on the remote control platform. At this time, the remote control platform can receive and respond to the vehicle start command, thereby establishing a communication connection with the on-board control unit of the unmanned cargo vehicle, and sending a remote start message to the on-board control unit through the communication connection. Of course, the remote control platform may have established a communication connection with the unmanned cargo vehicle in advance, and at this time, the remote control platform can directly use the established communication connection to send a remote start message to the on-board control unit.

[0021] Step 202: The vehicle control unit responds to the remote start message and determines whether the vehicle is awakened.

[0022] In implementation, after receiving the remote start message from the remote control platform, the on-board control unit first needs to determine whether the vehicle is in an awake state. Normally, the vehicle is in a low-power sleep state when not in use, and the on-board control unit will also enter a low-power mode to reduce energy consumption. The judgment of the awake state is mainly to detect whether the vehicle's electrical system is in an activated state, that is, whether the vehicle can immediately execute the power-on start process. If the vehicle has been awakened, the on-board control unit can directly skip the wake-up process and enter the subsequent power-on condition judgment. If the vehicle has not been awakened, a wake-up operation must be performed to enable the vehicle to meet further power-on condition judgments.

[0023] Step 203: If the vehicle has been awakened, the vehicle control unit determines in sequence whether the vehicle meets a plurality of preset first-level remote start conditions and second-level remote start conditions.

[0024] Among them, the first-level remote start conditions include at least one of the following: the vehicle's high-voltage electrical system is not activated, the power system is in the off state, and the driving mode is RFC mode; the second-level remote start conditions include at least one of the following: identity authentication passed, the electronic parking brake has been enabled, the charging status is not connected, and all the lock button switches in the vehicle are turned off.

[0025] In implementation, after confirming that the vehicle is in the awake state, the vehicle control unit may then perform a series of remote start condition checks to ensure that the power-on operation complies with safety regulations. The remote start conditions may include first-level remote start conditions and second-level remote start conditions.

[0026] The first level remote start conditions can be basic start conditions, which are used to ensure the stability of the vehicle and avoid abnormal power-on. The first level remote start conditions include but are not limited to the following:

[0004] The high-voltage electrical system is not activated: This condition ensures that the high-voltage system inside the vehicle is in a dormant state and needs to be powered on;

[0004] The power system is off: This condition prevents the power system from being powered on again if it is already on;

[0004] Driving mode is not RFC mode: RFC mode (Remote Function Control Mode) usually refers to a remote function control driving mode, which may involve automatic driving or remote driving functions. If the vehicle is in RFC mode, it means that the vehicle may be performing some automatic or remote driving operations and is not suitable for remote start. Therefore, during the remote start process, it is necessary to ensure that the vehicle is not in RFC mode.

[0027] The second level remote startup conditions are further safety startup conditions to ensure that the system and environment are powered on in a compliant and safe state. The second level remote startup conditions include but are not limited to:

[0004] Identity authentication passed: to verify the authentication information of the remote control platform and the vehicle control unit to ensure the legitimacy of the command;

[0004] The electronic parking brake has been activated to ensure that the vehicle is parked to avoid accidental movement due to misoperation;

[0004] Charging status is disconnected: to determine whether the vehicle is not connected to the charging device, to avoid executing intelligent power distribution processing when the vehicle is in charging state;

[0004] All the lock switches in the car are turned off: to confirm that the control switches in the car are in the off state to avoid misoperation after power-on.

[0028] Further, when checking the vehicle status according to the first level remote start condition or the second level remote start condition, each condition may be checked in sequence according to each level of remote start condition.

[0029] Step 204 : If the vehicle meets all the first-level remote start conditions and the second-level remote start conditions, the vehicle control unit controls the vehicle to power on, otherwise a remote start failure message is fed back to the remote control platform.

[0030] In implementation, when all the first-level remote start conditions and the second-level remote start conditions are checked and passed, the on-board control unit can perform power-on processing, activate the vehicle's high-voltage electrical system, and enter a fully started state. This operation indicates that the vehicle is in a powered-on state and can further respond to other remote operation commands or enter a working state.

[0031] If the vehicle fails to meet any of the conditions, the vehicle control unit will be unable to perform the power-on operation. At this time, the vehicle control unit can feedback a remote start failure message to the remote control platform, and the remote start failure message can include a failure reason code so that the management personnel or the operating system can analyze the cause of the start failure.

[0032] Step 205, if the vehicle is not awakened, the vehicle control unit controls to wake up the vehicle, closes the normally energized relay, and sequentially determines whether the vehicle meets a plurality of preset second-level remote start conditions.

[0033] In implementation, if the vehicle is still in a dormant state when receiving a remote start message, the on-board control unit may first perform a wake-up operation, which includes energizing a normally energized relay to restore power to the vehicle's electrical system, thereby enabling the on-board control unit to enter an active state.

[0034] After the vehicle is awakened, the vehicle control unit can directly check the second-level remote start conditions to ensure power-on in a safe state. The second-level remote start condition check can include verification of identity authentication, electronic parking brake status, charging connection status, and vehicle lock button switch status. This verification process ensures the safety of starting the vehicle after it is awakened.

[0035] Step 206 : If the vehicle meets all the second-level remote start conditions, the vehicle control unit controls the vehicle to power on, otherwise a remote start failure message is fed back to the remote control platform.

[0036] In implementation, when the vehicle is awakened and meets all the second-level remote start conditions, the on-board control unit will perform power-on processing, that is, activate the vehicle's high-voltage system, complete the power-on process, and enter an operational state.

[0037] If the vehicle fails to meet the second-level remote start conditions, the vehicle control unit will not be able to perform the power-on operation and will feedback the start failure message to the remote control platform. This failure feedback can help the remote control platform understand the real-time status of the vehicle so that it can take corresponding follow-up actions or prompt the user to check.

[0038] Furthermore, the processing of the above steps 202 to 206 may specifically be as follows:

[0004] STEP1: The vehicle control unit receives the remote start message and determines whether the vehicle is awakened. If not, the vehicle control unit first wakes up the vehicle and attracts the normally energized relay, then jumps to STEP5; if it is awakened, continue to STEP2.

[0039] STEP2: The vehicle control unit checks whether the vehicle's propulsion system is activated (PrplsnSysAtv). If PrplsnSysAtv=1, the vehicle is already on high voltage, and the vehicle control unit feeds back to the cloud (i.e., the remote control platform) to display "The vehicle is already on high voltage, remote start failed", and exits the remote start process; if PrplsnSysAtv=0, the vehicle is not on high voltage, and STEP3 is continued.

[0040] STEP3: The vehicle control unit checks whether the power mode (SystemPowerMode) is OFF: If SystemPowerMode=0, that is, the power mode is OFF, execute STEP6; if SystemPowerMode≠0, that is, the power mode is ON, continue to execute STEP4.

[0041] STEP4: The vehicle control unit checks whether the driving mode (vehicle control unit ControlModeStatus) is RFC mode: If the vehicle control unit ControlModeStatus = 1, that is, the driving mode is RFC mode, the vehicle control unit feedback message to the cloud to display "driving mode does not meet the remote start conditions", and exit the remote start process. If the vehicle control unit ControlModeStatus≠1, that is, the driving mode is not RFC mode, continue to execute STEP5.

[0042] STEP5: The vehicle control unit performs identity authentication to ensure the legitimacy and security of the remote start message source: If the identity authentication is successful, execute STEP6. If the identity authentication fails, the vehicle control unit sends a message back to the cloud to display "Identity authentication failed" and exit the remote start process.

[0043] STEP6: The vehicle control unit checks whether the electronic parking brake (EPB) status (EPBAppcnSts) is Applied: If EPBAppcnSts=1, the EPB status is Applied, and STEP7 is executed. If EPBAppcnSts≠1, the EPB status is not Applied, the vehicle control unit sends a message back to the cloud to display "EPB status does not meet the remote start conditions", and exits the remote start process.

[0044] STEP7: The vehicle control unit checks the connection status of the charging cable (B2V_ST1_ChgLine): If B2V_ST1_ChgLine≠1, the charging cable is not connected, and STEP8 is executed; if B2V_ST1_ChgLine=1, the charging cable is connected, and the vehicle control unit feeds back a message to the cloud to display "The vehicle charging cable is connected, and the remote start conditions are not met", and exits the remote start process.

[0045] STEP8: The vehicle control unit determines whether to pull the normally powered relay according to the power mode and check the lock switch status (LatchStatus): If the power mode is OFF (SystemPowerMode=0), first pull the normally powered relay, and then check the lock switch status. If the power mode is ON (SystemPowerMode=2), directly check the lock switch status.

[0046] If LatchStatus=1, that is, the lock switch is turned on, the vehicle control unit sends a message to the cloud to display "The lock switch is turned on, and the remote start condition is not met", and exits the remote start process. If LatchStatus≠1, that is, the lock switch is not turned on, execute STEP9.

[0047] STEP9: The vehicle control unit sends a high-voltage request instruction (SystemPowerMode=3) to the VCU (VehicleControl Unit) to control the vehicle to power on. The vehicle control unit determines whether PrplsnSysAtv changes from 0 to 1 within the specified time: If PrplsnSysAtv=1 within the specified time, the vehicle successfully powers on, and STEP10 is executed. If PrplsnSysAtv≠1 within the specified time, the vehicle fails to power on, and the vehicle control unit sends a message back to the cloud to display "Remote Start Timeout" and exit the remote start process.

[0048] STEP10: The vehicle control unit sends the remote start success status (RemVehStSts=1) to the IECU (Interior Electronic Control Unit). After receiving it, the IECU sends the message VoiceBroadcastCtrl=0x11 to request the voice alarm to alarm "Vehicle remote start successful".

[0049] STEP 11: The vehicle control unit sends a remote start success message to the cloud to display "Remote start successful", and the process ends.

[0050] The intelligent power distribution method for unmanned cargo vehicles disclosed in the embodiments of the present application is used to address the problem of insufficient security of intelligent power distribution control for unmanned cargo vehicles pointed out in the background technology. Through multiple verifications of the first-level and second-level remote start conditions, the legality and safety of the remote start operation are ensured. Specifically, the first-level conditions mainly ensure that the state of the vehicle's electrical system is suitable for power-on, such as ensuring that the high-voltage electrical system is activated and the power system is in the off state, while the second-level conditions further enhance operational safety, such as requiring identity authentication to be passed and the electronic parking brake to be enabled. This multi-level condition setting prevents the vehicle from being powered on in abnormal or unauthorized circumstances, effectively reduces operational risks, and ensures the safety of intelligent power distribution control.

[0051] Furthermore, the embodiment of the present application specially designs a two-layer judgment mechanism, namely whether the vehicle has been awakened and the first and second level condition verification. This mechanism ensures that in the remote start operation, the vehicle status must meet specific conditions before powering on, preventing powering on when key factors such as driving mode, electronic parking brake status, lock button switch, etc. are not suitable, and avoiding abnormal vehicle startup or potential accidents caused by misoperation.

[0052] In addition, the hierarchical condition design (i.e., first-level and second-level remote start conditions) also improves the flexibility of the system. By refining the remote start conditions and managing them in layers, the system can automatically adjust the power-on process according to the current state of the vehicle. For example, if the vehicle has been awakened, the system directly performs the verification of the first-level and second-level conditions and powers on; if the vehicle is in a dormant state, the system first performs the wake-up operation and then checks the second-level conditions. This design enables the system to flexibly respond to different vehicle states according to actual conditions, ensuring the smooth power-on and avoiding complex processes.

[0053] It is mentioned in the background technology that some intelligent power distribution control solutions have a low success rate, often because the actual state of the vehicle is not taken into account or the necessary conditions are not judged. The present application solution uses detailed state detection and condition judgment to make each remote start step based on the real-time state of the vehicle, thereby reducing the start failure caused by abnormal state. For example, the vehicle cannot be powered on directly in the sleep state, but when the solution detects the sleep state, it will automatically perform the wake-up operation and judge the start-up conditions after wake-up, thereby effectively improving the success rate of remote start. In addition, when the startup fails, the system will feedback the specific failure reason message to the remote control platform, so that the management personnel can make judgments and adjustments in time, further improving the reliability of the operation.

[0054] By making a preliminary judgment on the vehicle's wake-up state in step 202, unnecessary condition checks and high-voltage system activation can be avoided when the vehicle is not awakened, thereby reducing the energy consumption of the system in an idle state. In addition, the normally powered relay in this solution is only energized when the vehicle needs to be awakened, thereby avoiding unnecessary power loss and making the entire remote start process more energy-efficient and efficient.

[0055] The multi-layer condition judgment and flexible power-on control mechanism make the system highly intelligent. Through multiple verification and feedback mechanisms of conditions, the system can automatically adapt to different remote start scenarios and flexibly implement intelligent power distribution control while ensuring safety. This intelligent design can adapt to various complex working conditions, improve the overall operating experience of unmanned cargo vehicles, and provide a more convenient and efficient solution for remote management.

[0056] In one embodiment, before determining whether the vehicle is awakened, it also includes: the on-board control unit responds to the remote start message, calls the on-board sensor unit to obtain vehicle environmental information, and sends the vehicle environmental information to the remote control platform; the remote control platform determines whether the vehicle has a startup environment risk based on the vehicle environmental information; if so, the remote control platform sends an environmental information monitoring instruction to the on-board control unit, so that the on-board control unit continuously feeds back the vehicle environmental information; if not, the remote control platform sends a startup confirmation message to the on-board control unit.

[0057] In practice, after receiving the remote start message, the vehicle control unit will not immediately determine whether the vehicle is awakened, but will first call the vehicle sensor unit to obtain the vehicle's current environmental information. For example, the sensor obtains data such as temperature and humidity, terrain, and obstacle distance around the vehicle, and organizes these data into environmental information and sends it to the remote control platform.

[0058] After receiving the vehicle environment information, the remote control platform analyzes and determines whether the current environment is suitable for remote start operation. The specific judgment basis may include: the temperature is too high or too low, whether there are obstacles around the vehicle, whether the humidity exceeds the standard, etc. At this time, if the remote control platform determines that there is a start risk in the vehicle environment, such as the surrounding obstacles are too close or the terrain is not suitable for power-on start, it is considered that there is a start risk.

[0059] If the remote control platform detects a startup environmental risk, it will send an environmental information monitoring command to the vehicle control unit. This command causes the vehicle control unit to enter a continuous monitoring mode and regularly feed back environmental information to the remote control platform to further monitor changes in the vehicle environment. This process will continue until the remote control platform determines that the environmental risk has disappeared.

[0060] If the remote control platform determines that the vehicle environment is not risky, it will send a startup confirmation message to the vehicle control unit. This message confirms that the vehicle environment is safe and suitable for startup operations, and the vehicle control unit can continue to execute subsequent wake-up and condition judgment processes to perform intelligent power distribution.

[0061] In one embodiment, after the remote control platform determines whether the vehicle has a startup environment risk based on the vehicle environment information, it also includes: the remote control platform determines the maximum elimination time corresponding to the startup environment risk; if the maximum elimination time is less than the preset time threshold, the remote control platform sends a delayed start confirmation message to the vehicle control unit.

[0062] In implementation, in the above scheme, the remote control platform determines whether there is a risk in the startup environment through vehicle environmental information. On this basis, the concept of "maximum elimination time" can be introduced. When an environmental risk exists, the remote control platform further analyzes the maximum elimination time of the risk under normal circumstances. For example, the environmental risk may be caused by short-term obstacle detection, slight slippery or other temporary factors, and the system will determine its maximum possible duration based on the risk type. This maximum elimination time can be estimated through a preset elimination time database or an analysis algorithm based on the risk type.

[0063] After obtaining the maximum elimination time, the remote control platform compares it with the preset time threshold set in the system. For example, if the preset time threshold is 5 minutes, and the system determines that the maximum elimination time is 3 minutes, the system will consider the environmental risk to be temporary and can be eliminated by itself within a reasonable time, and will not have a long-term impact on remote startup.

[0064] If the maximum elimination time is less than the preset time threshold, the remote control platform sends a "delayed start confirmation message" to the vehicle control unit. The purpose of this message is to inform the vehicle control unit to wait for the environment to return to a risk-free state within the estimated time, rather than immediately interrupting the remote start operation. After receiving the delayed start confirmation message, the vehicle control unit will enter a waiting state and delay the power-on operation until the risk is eliminated or the maximum waiting time for the delayed start is reached.

[0065] In one embodiment, the method also includes: when the identity authentication fails, the vehicle-mounted control unit sends a historical authentication information set to the remote control platform, the historical authentication information set containing correct and incorrect identity authentication information and identity authentication information of the historical records; the remote control platform responds to the selection instruction for the identity authentication information in the historical authentication information set, and determines the selected identity authentication information; the remote control platform sends the selected identity authentication information to the vehicle-mounted control unit so that the vehicle-mounted control unit performs identity confirmation processing.

[0066] In practice, when the remote control platform initiates a start command through a remote start message, the vehicle control unit needs to verify the identity authentication. If the identity authentication fails (for example, verification failure, credential expiration, etc.), the vehicle control unit will send a historical authentication information set to the remote control platform. This set contains all past identity authentication data, including successful and failed authentication records. The historical authentication information set provides important background information to help the remote control platform analyze the cause of the identity authentication failure and make corresponding processing.

[0067] The historical authentication information set is sent by the vehicle control unit to the remote control platform, and the remote control platform can select the appropriate identity authentication information based on the received historical information and the instructions selected by the user. The remote control platform can provide a selection interface to allow the user to select the identity information that was previously successfully authenticated or to select the most appropriate authentication method based on other security factors. For example, the user may select an identity authentication method that was previously verified, or choose to perform a new identity authentication.

[0068] After the remote control platform determines the selected authentication information, it sends the information back to the vehicle control unit. At this point, the vehicle control unit uses the authentication information received from the remote platform to perform identity confirmation processing. This process involves the vehicle control unit verifying the validity of the authentication information, ensuring that it matches the security record in the vehicle control unit system, and completing the authentication process.

[0069] The vehicle control unit receives the selected identity authentication information sent by the remote platform, and the vehicle control unit can perform identity confirmation processing on the information. The key to this process is to verify whether the information is correct and complies with the preset security rules. If the identity confirmation is successful, the system can continue to perform intelligent power distribution control operations. If the identity confirmation fails, the vehicle control unit can re-authenticate the request or feedback an error message to the remote control platform.

[0070] In one embodiment, after the on-board control unit controls the vehicle to perform power-on processing, it also includes: the on-board control unit sends a multimodal identity authentication request to the remote control platform; the remote control platform responds to the multimodal identity authentication request and sends the acquired multimodal identity authentication data to the on-board control unit; the on-board control unit calculates the comprehensive identity authentication score based on the multimodal identity authentication data; if the comprehensive identity authentication score is not greater than the preset score threshold, the on-board control performs power-off processing.

[0071] In practice, after the vehicle control unit completes the power-on operation of the vehicle, in order to further ensure the safety of operation, the vehicle control unit will send a multi-modal authentication request to the remote control platform. This request is intended to confirm the user's identity at multiple levels through multiple authentication modes (such as facial recognition, fingerprint recognition, voice recognition, etc.).

[0072] After the remote control platform receives a multi-modal authentication request from the vehicle control unit, the platform will obtain authentication data in multiple modes according to the request. These data may include biometric information, user behavior characteristics, etc. Through the processing of the remote control platform, more comprehensive and accurate authentication information can be provided to ensure the security of remote control.

[0073] After obtaining the multimodal authentication data, the remote control platform will send this data to the vehicle control unit. The multimodal authentication data consists of a variety of different authentication information, and the vehicle control unit further determines the identity credibility of the operating user based on this information.

[0074] After receiving the multimodal authentication data, the vehicle control unit will analyze and process the data and calculate the comprehensive authentication score. The comprehensive authentication score is a weighted result based on the multimodal authentication information and represents the reliability of the operating user's identity. The higher the score, the greater the probability of passing the authentication; the lower the score, the less credible the authentication information.

[0075] The vehicle control unit compares the calculated identity authentication comprehensive score with the preset score threshold. If the identity authentication comprehensive score is not greater than the preset score threshold, it means that the verification does not meet the safety requirements. The system will perform power-off processing and cut off the power-on state of the vehicle to ensure that the vehicle is not continued to be operated by unauthorized users. This step can effectively prevent illegal users from controlling the vehicle through the remote platform or vehicle control unit, and improve the safety of vehicle operation.

[0076] In one embodiment, the remote start message also includes an engineering task instruction; the method also includes: the on-board control unit determines whether the current vehicle state meets the state requirements corresponding to the engineering task instruction based on the engineering task instruction; if so, the on-board control unit responds to the remote start message, otherwise, it feedbacks a task state non-compliance message.

[0077] In the implementation, an engineering task instruction is added to the remote start message initiated by the remote control platform, indicating that the vehicle needs to enter a specific engineering task mode after powering on. The engineering task instruction contains the specific requirements and operation instructions of the task to ensure that the vehicle can perform status verification according to the task requirements.

[0078] After receiving the remote start message, the vehicle control unit not only determines the power-on condition, but also extracts the engineering task instruction and verifies the current state of the vehicle according to its requirements. For example, the engineering task instruction may require the vehicle to be in a certain operating mode or a specific loading state, and the vehicle control unit will determine whether the current vehicle state meets these specific state requirements.

[0079] If the vehicle control unit detects that the current state of the vehicle meets the state requirements of the engineering task instruction, it indicates that the vehicle is ready to perform the corresponding engineering task. At this time, the vehicle control unit will continue to respond to the remote start message and perform the power-on operation to put the vehicle into a state ready to perform the engineering task.

[0080] If the vehicle status does not meet the requirements of the engineering task instruction, the on-board control unit will not continue to power on, but will feedback the task status inconsistent message to the remote control platform. This feedback message can help the remote control platform to timely understand the difference between the vehicle status and the task requirements, and avoid the vehicle starting and executing the engineering task in an unsuitable state, thereby ensuring the safety of the operation and the executability of the task.

[0081] In one embodiment, the remote control platform responds to the vehicle start instruction and sends a remote start message to the vehicle control unit, including: the remote control platform selects a target vehicle from the preset cargo unmanned vehicles according to the engineering task instruction, and sends a remote start message to the vehicle control unit of the target vehicle.

[0082] In practice, after receiving the vehicle start command, the remote control platform selects target vehicles that meet the task conditions from the managed cargo unmanned vehicle library based on the specific requirements of the engineering task instruction (such as the vehicle type, load capacity, location, etc. required for the task). For example, for a handling task, the platform can select vehicles with a high load capacity and within the task area to ensure that the selected target vehicles meet the actual requirements of the task.

[0083] After selecting the target vehicle, the remote control platform sends a remote start message to the vehicle's onboard control unit through a communication connection. This operation ensures that only the specific target vehicle receives the remote start command during the mission execution, thereby improving the accuracy and execution efficiency of the mission command.
