Abstract
Description
Technical Field
[0001] The invention relates to a remote locking control method for an electric wide-body mining dump truck, belonging to the technical field of vehicle remote control. Background Art
[0002] In the construction machinery financing leasing and installment payment business, remote vehicle locking technology has become a core means for OEMs to constrain customers to repay and control illegal modifications. However, the existing vehicle locking system has significant technical bottlenecks in terms of security, reliability and anti-tampering capabilities, which restricts its actual application effect.
[0003] Traditional vehicle locking systems lack the ability to dynamically perceive the working environment and equipment status. Their vehicle locking command triggering mechanism relies only on a single repayment status judgment, and does not integrate safety dimensions such as slope detection, terrain analysis, and equipment operation posture assessment. This results in vehicle locking operations possibly occurring in dangerous working conditions, such as working on a steep slope or in an area close to a cliff, which can easily cause equipment to lose control or even overturn, seriously threatening the safety of operators and increasing the risk of equipment damage.
[0004] The verification mechanism of the vehicle locking logic in the existing technology is complex and lacks fault tolerance. The system is susceptible to communication delays, signal interference and encryption protocol loopholes, and the vehicle locking command fails or is triggered by mistake frequently. Specifically, the overdue repayment equipment cannot be effectively locked, or the normal operating equipment is accidentally locked, which not only weakens the effectiveness of technical constraints, but also directly leads to a decrease in equipment attendance, damaging the economic interests of customers and the brand reputation of the OEM.
[0005] In addition, traditional systems have design flaws in hardware protection and accessory authentication. The core components of the vehicle are not equipped with physical anti-dismantling structures and electronic self-destruction mechanisms. After illegal dismantling, the system completely loses remote control capabilities. At the same time, key components lack original identity binding and dynamic verification functions, making it difficult to trace illegal modifications. When customers privately replace non-original accessories and cause malfunctions, it is often impossible to effectively distinguish the responsible parties, which often leads to three-guarantee claims disputes, causing unnecessary economic losses and legal risks to the OEM. Summary of the invention
[0006] Purpose of the invention: In view of the shortcomings of the prior art, the present invention provides a remote locking control method for an electric wide-body mining dump truck. The present invention realizes intelligent avoidance of dangerous conditions, hierarchical fault-tolerant locking control, hardware-level tamper-proof protection, and collaborative management of business risks by setting locking conditions, A / B level dual protection system, solid-state key binding and physical anti-dismantling design.
[0007] Technical solution: A remote locking control method for an electric wide-body mining dump truck, specifically: The cloud platform screens out the vehicles during the lease period and sends a binding instruction to the in-vehicle intelligent computing instrument through the T-BOX terminal, so that the VCU controller and the in-vehicle intelligent computing instrument complete the binding; The cloud platform determines whether there is an arrears situation for the vehicles during the lease period. If there is an arrears situation that has not been repaid, the cloud platform sends a first-level vehicle locking instruction to the T-BOX terminal. If there is no arrears situation that has not been repaid, after each power-on of the vehicle, the T-BOX terminal sends a heartbeat message anomaly detection instruction to the VCU controller. The VCU controller obtains the heartbeat message from the vehicle core components. If the heartbeat message is not obtained, the A-level vehicle locking protection mode is started; if the heartbeat message is obtained, it is judged whether the heartbeat message is correct. If it is correct, the VCU controller does not act. If it is incorrect, the B-level vehicle locking protection mode is started. When the vehicle is in the A-level vehicle locking protection mode or the B-level vehicle locking protection mode, if the VCU controller obtains a correct heartbeat message, the T-BOX terminal sends an unlocking instruction to the VCU controller, and the vehicle resumes normal use; When the cloud platform detects that the vehicle has both an arrears situation that has not been repaid and a heartbeat message anomaly situation, the B-level vehicle locking protection mode is preferentially executed.
[0008] Preferred option, the specific steps of the binding instruction are as follows: After the in-vehicle intelligent computing instrument receives the binding instruction sent by the T-BOX terminal through the CAN bus, the in-vehicle intelligent computing instrument sends a binding request to the VCU controller through the CAN bus. The VCU controller sends activation status flag bit data to respond to the binding request. When the in-vehicle intelligent computing instrument detects that the activation status flag bit data is correct, the binding is completed; if it is incorrect, the in-vehicle intelligent computing instrument sends the in-vehicle intelligent computing instrument ID and the solid-state secret key to the VCU controller to complete the binding with the VCU controller.
[0009] Preferred option, after the binding of the VCU controller and the in-vehicle intelligent computing instrument is completed, a handshake verification is required. Specifically: The in-vehicle intelligent computing instrument sends a handshake verification request to the VCU controller through the CAN bus. When the VCU controller receives the request instruction sent by the in-vehicle intelligent computing instrument, it will immediately send a verification code instruction to the in-vehicle intelligent computing instrument. When the in-vehicle intelligent computing instrument reads the verification code instruction and the received verification code instruction is not 0, it is considered that the correct verification code instruction has been received. The in-vehicle intelligent computing instrument decodes to obtain the verification password, and then sends the verification password to the VCU controller through the CAN bus. After receiving the verification password, the VCU controller needs to verify the verification password, and at the same time, the VCU controller informs the in-vehicle intelligent computing instrument of the verification result through the CAN bus; When the in-vehicle intelligent computing instrument receives a message with successful verification, the handshake verification between the in-vehicle intelligent computing instrument and the VCU controller is successful; when the in-vehicle intelligent computing instrument receives a message with failed verification, the in-vehicle intelligent computing instrument needs to re-request a new verification code instruction, decode the new verification code instruction to obtain a new verification password and send it to the VCU controller for verification again until the handshake verification between the in-vehicle intelligent computing instrument and the VCU controller is successful.
[0010] Preferred option, the specific A-level vehicle locking protection mode is as follows: The VCU controller obtains the heartbeat message of the vehicle's core components. If the VCU controller cannot obtain the heartbeat message of the vehicle's core components during the first power-on, the VCU controller does not act and records the warning value as 1; When the vehicle is powered on for the second time and the VCU controller cannot obtain the heartbeat message of the vehicle's core components, record the warning value as 2, and determine whether the current vehicle meets the vehicle locking condition. If it meets, the T-BOX terminal sends a secondary vehicle locking instruction to the VCU controller, and the VCU controller executes the secondary vehicle locking instruction; if it does not meet, wait for the vehicle to be powered on for the third time and continue to obtain the heartbeat message; When the vehicle is powered on for the third time and the VCU controller still cannot obtain the heartbeat message of the vehicle's core components, record the warning value as 3, and determine whether the current vehicle meets the vehicle locking condition. If it meets, the T-BOX terminal sends a primary vehicle locking instruction to the VCU controller, and the VCU controller executes the primary vehicle locking instruction and reports to the cloud platform to mark the vehicle; If it does not meet, wait for the next power-on to judge the vehicle locking condition again to execute the primary vehicle locking instruction. If the warning value reaches 5 and the primary vehicle locking instruction has still not been executed, enforce the safety locking mode; When the T-BOX terminal sends an unlocking instruction to the VCU controller and the vehicle resumes normal use, the warning value is cleared.
[0011] Preferred option, the specific B-level vehicle locking protection mode is as follows: The T-BOX terminal collects evidence and reports to the cloud platform to mark that the vehicle has abnormal components. The cloud platform sends a liability notice to the user and determines whether the current vehicle meets the vehicle locking condition. If it meets, control the vehicle to cut off the power output and activate the mechanical brake. If it does not meet, wait for the next power-on and detect the vehicle locking condition again. If the cumulative power-on times reach 5 and the power output has still not been cut off and the mechanical brake has not been activated, enforce the safety locking mode; The evidence collected by the T-BOX terminal is: the last valid communication record of the abnormal component; The data record of the surrounding sensors within 10 minutes; The engine compartment picture taken by the in-vehicle camera.
[0012] Preferred option: The primary vehicle locking instruction is that the motor output power is limited to 70% of the rated value for a duration ≤ 24 hours; The secondary vehicle locking instruction is that the motor output power is limited to 30%.
[0013] Preferred option: The vehicle locking conditions are specifically as follows: The vehicle speed is less than 5 km / h; The horizontal inclination angle of the inclination sensor is less than 30°; The weighing system detects that the total installed weight of the whole machine is less than 30 tons; The temperature sensor detects that the ambient temperature is between -15°C and 45°C; The ultrasonic sensor detects that there is no cliff within 10 meters nearby.
[0014] Preferred option: The specific safety locking mode is as follows: The motor output power is limited to 80% of the rated value, and the maximum vehicle speed is limited to 20 km / h; The Beidou positioning is activated for continuous tracking, and a forced maintenance instruction is sent to the nearest service station.
[0015] Preferred option: It also includes an emergency exemption mode for vehicle locking, specifically as follows: When any of the following situations is detected, the vehicle locking restriction is suspended for 24 hours: The brake pedal pressure continuously > 80 kPa for more than 3 seconds; The safety airbag trigger signal is valid; The gyroscope detects that the roll angle > 45 degrees.
[0016] Preferred option: The instruction interaction method between the T-BOX terminal and the VCU controller is as follows: When the T-BOX terminal receives an instruction, it saves the instruction; If the vehicle is in the powered-on state, the T-BOX terminal sends the saved instruction to the VCU controller via the CAN bus. When the VCU controller receives the instruction for more than 3 frames, it needs to respond to the T-BOX terminal until a new instruction is received or the power is cut off; If the T-BOX terminal does not receive the response instruction from the VCU controller, it sends the instruction once every 1 s until the response instruction from the VCU controller is received; If the T-BOX terminal receives the response instruction from the controller, it immediately stops sending the instruction, feeds back the successful sending of the instruction to the cloud platform, and clears the saved instruction; When the vehicle is in the powered-off state, it waits until the next power-on when the T-BOX terminal immediately sends the saved instruction to the VCU controller and executes the above interaction steps when the vehicle is in the powered-on state.
[0017] Beneficial effects: By integrating slope detection, terrain analysis, and equipment attitude assessment, the present invention dynamically determines the car locking conditions, avoids forced car locking in dangerous scenarios such as large inclination angles and cliff-edge areas, combines with the emergency exemption mode to ensure operation safety, and realizes intelligent avoidance of dangerous working conditions; Construct an A / B-level dual protection system. Through the heartbeat message verification and warning value accumulation trigger mechanism, accurate locking of overdue equipment and avoidance of false triggering caused by communication interference are realized. The dynamic authentication of the check code improves the reliability of the instruction, and hierarchical fault-tolerant car locking control is achieved; Based on the binding of solid-state keys and physical anti-disassembly design, automatic safety locking is triggered after illegal disassembly; non-original factory modifications are identified through dynamic verification of accessory feature codes, and the cloud evidence chain is used to solidify the basis for liability determination, realizing anti-tampering protection at the hardware level; The first-level car locking instruction is directly connected to the repayment status to strengthen the binding effect. Combined with the Beidou positioning tracking and service linkage mechanism, the attendance rate of the equipment and the capital recovery efficiency are guaranteed, and the collaborative control of business risks is realized.

[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.
[0021] In the description of the present invention, it should be understood that the orientation or positional relationships indicated by the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. are based on the orientation or positional relationships shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present invention.
[0022] In the present invention, unless otherwise clearly specified and defined, the first feature being "on" or "under" the second feature may include the direct contact between the first and second features, or may include the situation where the first and second features are not in direct contact but in contact through additional features therebetween. Moreover, the first feature being "above", "over" and "on top of" the second feature includes that the first feature is directly above and obliquely above the second feature, or merely indicates that the horizontal height of the first feature is higher than that of the second feature. The first feature being "under", "beneath" and "underneath" the second feature includes that the first feature is directly below and obliquely below the second feature, or merely indicates that the horizontal height of the first feature is lower than that of the second feature.
[0023] As Figure 1 shown, a remote locking control method for an electric wide-body mining dump truck is specifically as follows: The cloud platform screens out the vehicles during the lease period, and sends a binding instruction to the in-vehicle intelligent computing instrument through the T-BOX terminal to complete the binding between the VCU controller and the in-vehicle intelligent computing instrument; The cloud platform determines whether there is an arrears situation for the vehicles during the lease period. If there is an arrears situation that has not been repaid, the cloud platform sends a first-level vehicle locking instruction to the T-BOX terminal, that is, the motor output power is limited to 70% of the rated value for a duration ≤ 24 hours. If there is no arrears situation that has not been repaid, after each power-on of the vehicle, the T-BOX terminal sends a heartbeat message abnormality detection instruction to the VCU controller, and the VCU controller obtains the heartbeat message from the vehicle core components. If the heartbeat message is not obtained, the A-level vehicle locking protection mode is started; if the heartbeat message is obtained, it is judged whether the heartbeat message is correct. If it is correct, the VCU controller does not act. If it is incorrect, the B-level vehicle locking protection mode is started. When the vehicle is in the A-level vehicle locking protection mode or the B-level vehicle locking protection mode, if the VCU controller obtains a correct heartbeat message, the T-BOX terminal sends an unlocking instruction to the VCU controller, and the vehicle resumes normal use; When the cloud platform detects that the vehicle has both an arrears situation that has not been repaid and a heartbeat message abnormality situation, the B-level vehicle locking protection mode is preferentially executed.
[0024] The specific steps of the binding instruction are as follows: After the in-vehicle intelligent computing instrument receives the binding instruction sent by the T-BOX terminal via the CAN bus, the in-vehicle intelligent computing instrument sends a binding request to the VCU controller via the CAN bus. The VCU controller sends activation status flag bit data to respond to the binding request. When the in-vehicle intelligent computing instrument detects that the activation status flag bit data is correct, the binding is completed; if it is incorrect, the in-vehicle intelligent computing instrument sends the in-vehicle intelligent computing instrument ID and the solid key to the VCU controller to complete the binding with the VCU controller. The activation status flag bit data specifically is that when the flag bit data is 1, it represents that the binding has been completed, and when it is 0, it represents that the binding has not been completed. Embodiment 1
[0025] After completing the binding between the VCU controller and the in-vehicle intelligent computing instrument, handshake verification is required. Specifically: The in-vehicle intelligent computing instrument sends a handshake verification request to the VCU controller via the CAN bus. When the VCU controller receives the request instruction sent by the in-vehicle intelligent computing instrument, it will immediately send a verification code instruction to the in-vehicle intelligent computing instrument. When the in-vehicle intelligent computing instrument reads the verification code instruction and the received verification code instruction is not 0, it is considered that the correct verification code instruction has been received. The in-vehicle intelligent computing instrument decodes to obtain the verification password and then sends the verification password to the VCU controller via the CAN bus. After receiving the verification password, the VCU controller needs to verify the verification password and at the same time the VCU controller informs the in-vehicle intelligent computing instrument of the verification result via the CAN bus; When the in-vehicle intelligent computing instrument receives the message indicating successful verification, the handshake verification between the in-vehicle intelligent computing instrument and the VCU controller is successful; when the in-vehicle intelligent computing instrument receives the message indicating failed verification, the in-vehicle intelligent computing instrument needs to request a new verification code instruction again, decode the new verification code instruction to obtain a new verification password and send it to the VCU controller for verification again until the handshake verification between the in-vehicle intelligent computing instrument and the VCU controller is successful.
[0026] The specific A-level vehicle locking protection mode is as follows: The VCU controller obtains the heartbeat message of the vehicle's core components. If the VCU controller cannot obtain the heartbeat message of the vehicle's core components during the first power-on, the VCU controller does not act and records the warning value as 1; When the vehicle is powered on for the second time and the VCU controller cannot obtain the heartbeat message of the vehicle's core components, record the warning value as 2, and determine whether the current vehicle meets the vehicle locking condition. If it meets, the T-BOX terminal sends a secondary vehicle locking instruction to the VCU controller, that is, the motor output power is limited to 30%, and the VCU controller executes the secondary vehicle locking instruction; if it does not meet, wait until the vehicle is powered on for the third time and continue to obtain the heartbeat message; After the vehicle is powered on for the third time, if the VCU controller still fails to receive the heartbeat message of the vehicle's core components, record the warning value as 3, and determine whether the current vehicle meets the vehicle locking condition. If it meets the condition, the T-BOX terminal sends a first-level vehicle locking instruction to the VCU controller. The VCU controller executes the first-level vehicle locking instruction and reports to the cloud platform to mark the vehicle. If it does not meet the condition, wait until the next power-on and then judge the vehicle locking condition again to execute the first-level vehicle locking instruction. If the warning value reaches 5 and the first-level vehicle locking instruction still has not been executed, enforce the safety locking mode. When the T-BOX terminal sends an unlocking instruction to the VCU controller and the vehicle resumes normal use, the warning value is cleared.
[0027] The specific B-level vehicle locking protection mode is as follows: The T-BOX terminal collects evidence and reports to the cloud platform to mark that the vehicle has abnormal components. The cloud platform sends a liability notice to the user and determines whether the current vehicle meets the vehicle locking condition. If it meets the condition, control the vehicle to cut off the power output and activate the mechanical brake. If it does not meet the condition, wait until the next power-on and then detect the vehicle locking condition again. If the cumulative power-on times reach 5 times and the power output has not been cut off and the mechanical brake has not been activated, enforce the safety locking mode. The evidence collected by the T-BOX terminal is: the last valid communication record of the abnormal component; The data record of the surrounding sensors within 10 minutes; The engine room picture taken by the on-vehicle camera.
[0028] The specific vehicle locking conditions are as follows: The vehicle speed is less than 5 km / h; The horizontal inclination angle of the inclination sensor is less than 30°; The weighing system detects that the total installed weight of the whole machine is less than 30 tons; The temperature sensor detects that the ambient temperature is between -15° and 45°; The ultrasonic sensor detects that there is no cliff within 10 meters nearby.
[0029] The specific safety locking mode is as follows: The motor output power is limited to 80% of the rated value, and the maximum vehicle speed is limited to 20 km / h; activate the Beidou positioning for continuous tracking and send a forced maintenance instruction to the nearest service station. Embodiment 2
[0030] It also includes an emergency exemption mode for vehicle locking, specifically: When any of the following situations is detected, suspend the vehicle locking restriction for 24 hours: The brake pedal pressure continuously > 80 kPa for more than 3 seconds; The airbag trigger signal is valid; The gyroscope detects that the roll angle > 45 degrees.
[0031] The instruction interaction method between the T-BOX terminal and the VCU controller is as follows: When the T-BOX terminal receives an instruction, it saves the instruction. If the vehicle is in the powered-on state, the T-BOX terminal sends the saved instruction to the VCU controller via the CAN bus. If the VCU controller receives the instruction for more than 3 frames, it needs to reply to the T-BOX terminal until it receives a new instruction or is powered off. If the T-BOX terminal does not receive the reply instruction from the VCU controller, it sends the instruction once every 1 s until it receives the reply instruction from the VCU controller. If the T-BOX terminal receives the reply instruction from the controller, it immediately stops sending the instruction, feeds back to the cloud platform that the instruction has been sent successfully, and clears the saved instruction. When the vehicle is in the powered-off state, wait until the next power-on, and the T-BOX terminal immediately sends the saved instruction to the VCU controller to execute the above interaction steps when the vehicle is in the powered-on state. Embodiment III
[0032] When the cloud platform sends an unbinding instruction to the in-vehicle intelligent computing instrument from the T-BOX terminal, the in-vehicle intelligent computing instrument sends an unbinding request to the VCU controller via the CAN bus. After receiving it, the VCU controller sends a decoded verification code to the in-vehicle intelligent computing instrument. The in-vehicle intelligent computing instrument decodes to obtain the unbinding password and sends the unbinding password to the VCU controller via the CAN bus for verification. If the verification passes, the unbinding is performed, and it is informed via the CAN bus that the VCU controller has completed the unbinding. If the verification fails, the in-vehicle intelligent computing instrument needs to request a new unbinding verification code again, decode the new unbinding password based on the new unbinding verification code and send it to the VCU controller for verification again until the in-vehicle intelligent computing instrument and the VCU controller are successfully unbound.
