Description

Technical Field

[0001] This invention relates to the field of electric vehicle control technology, specifically to a control method and system for a pure electric heavy-duty commercial vehicle in a strong magnetic environment mode. Background Technology

[0002] With the global trend towards green and low-carbon development, pure electric commercial vehicles are being widely used. However, in strong magnetic field environments, the core electronic control systems of these vehicles, such as the vehicle control unit (VCU), battery management system (BMS), and automatic manual transmission (AMT) controller, are highly susceptible to electromagnetic interference, leading to a series of serious problems, including but not limited to: steering wheel malfunction, incorrect gear position signal recognition, distorted throttle and brake signals, ECU crashes or burnout, and the inability to regenerate power after an abnormal power outage in the vehicle's high-voltage system. Particularly in high magnetic field environments such as those in the aluminum electrolysis industry, the risk of steering wheel malfunction increases when vehicles are near electrolytic cells. Automatic transmission vehicles are especially vulnerable, potentially experiencing problems such as inability to recognize gears, unresponsive throttle, or even burnt-out circuit boards. Currently, many vehicles struggle to maintain stable operation in high magnetic environments.

[0003] Currently, a common approach is to accelerate the vehicle before entering a strong magnetic field, relying on inertia to propel it through. However, this method has significant limitations, only applicable to specific paths, lacking universality, and requiring high levels of driver experience and judgment, posing significant safety hazards. Therefore, there is an urgent need in this field for a technical solution that enables pure electric commercial vehicles to operate stably, reliably, and safely in strong magnetic environments. This would not only better leverage the advantages of pure electric commercial vehicles and reduce energy consumption but also enhance their applicability and meet industry needs. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of existing technologies and provide a control method and system for strong magnetic environment modes for pure electric heavy-duty commercial vehicles. This enables the vehicle to actively sense and intelligently respond to strong magnetic interference, ensuring basic driving functions and operational safety in extreme electromagnetic environments.

[0005] The present invention solves the above problems through the following technical solution:

[0006] A control method for a pure electric heavy-duty commercial vehicle in a strong magnetic environment includes the following steps:

[0007] S1. Mode Trigger: The driver manually operates the strong magnetic environment switch. The driver determines whether the vehicle has entered the strong magnetic environment mode based on whether the strong magnetic environment switch is pressed. If not, the normal driving procedure will run. If so, the vehicle will enter the strong magnetic environment mode.

[0008] S2. Signal Processing and Shielding: Upon entering the strong magnetic environment mode, the vehicle control unit (VCU) sends a strong magnetic environment mode operation signal to the battery management system (BMS) via the CAN bus and performs the following shielding operations:

[0009] Shield the fault signals sent by the BMS to the CAN bus;

[0010] Shield the VCU from receiving and forwarding low-level alarm signals to the CAN bus;

[0011] S3, Transmission control switch: The VCU stops sending upshift / downshift control commands to the automatic mechanical transmission (AMT), thus disabling the automatic shifting function of the AMT.

[0012] At the same time, the vehicle no longer needs to be powered on / off or shift gears by pressing the brake pedal.

[0013] S4, Manual Gear Control: Enables the D and R manual switches located in the driver's cab, which are independent of the original gear controller; the VCU directly receives the hard-wired signal from the manual switch and directly controls the vehicle gear according to its closed state.

[0014] As a further improvement of the present invention, in step S4, directly controlling the vehicle gear position based on the received closed state of the switch specifically includes:

[0015] When the D gear switch is closed and the R gear switch is open, the VCU controls the vehicle to enter D gear;

[0016] When the D gear switch is off and the R gear switch is on, the VCU controls the vehicle to enter R gear.

[0017] When the D and R switches are closed or open at the same time, the VCU controls the vehicle to shift into N gear.

[0018] As a further improvement of the present invention, in S4, the VCU directly monitors the corresponding pins of D and R gears to obtain the current closed state of D and R gears.

[0019] As a further improvement of the present invention, the control method further includes:

[0020] S5. When the strong magnetic switch is disconnected, the vehicle's power on / off and gear shifting are restored to enable when the brake pedal is pressed, and the shielding operation in S2 is no longer performed.

[0021] As a further improvement of the present invention, the control method includes the following steps before S1:

[0022] S01. Environmental perception and prediction: The magnetic field strength of the vehicle's environment is monitored in real time by multiple magnetometer arrays arranged around the vehicle.

[0023] S02. Based on the monitored magnetic field strength, establish and update the digital twin model of the magnetic environment in real time to map the topological structure of the magnetic field where the vehicle is located.

[0024] S03. The LSTM neural network algorithm is used to predict the trend of magnetic field changes, and the corresponding graded protection strategy is triggered in advance based on the prediction results.

[0025] As a further improvement of the present invention, the graded protection strategy includes: a three-level protection strategy to cope with different magnetic field strengths; specifically:

[0026] When the magnetic field strength is predicted or monitored to reach the first threshold of 500-1500 Gauss, Level I protection is activated, including initiating sensor redundancy verification and reducing the bus communication frequency.

[0027] When the magnetic field strength is predicted or monitored to reach the second threshold of 1500-3000 Gauss, Level II protection is activated, including the execution of "manual gear control" and "signal processing and shielding".

[0028] When the predicted or monitored magnetic field strength reaches the third threshold > 3000 Gauss, Level III protection is activated, including activating the fully mechanical backup control system and cutting off the power supply to magnetic field-sensitive electronic equipment.

[0029] As a further improvement of the present invention, the hierarchical protection strategy further includes: signal transmission anti-interference; specifically:

[0030] Frequency hopping communication protocol: The VCU and the actuator adopt frequency adaptive switching, and automatically switch to the backup frequency band when encountering interference;

[0031] Peak-shifting time windows: Intelligent allocation of signal transmission periods for each controller to avoid electromagnetic resonance caused by concentrated transmission;

[0032] Quantum-encrypted transmission: Critical control commands are encrypted using quantum random numbers to prevent signals from being maliciously tampered with.

[0033] As a further improvement of the present invention, the control method further includes the following before S1:

[0034] S04, Innovations in the Human-Machine Interaction Layer include: an immersive state-aware interface and multimodal backup. The immersive state-aware interface includes: a magnetic fluid display screen on the center console that maintains stable display even in strong magnetic environments; visualization of magnetic fields, which intuitively displays the distribution density of magnetic field lines through dynamic particle flow; and a haptic feedback steering wheel with a built-in magnetorheological fluid device that provides different damping sensations according to the magnetic field strength.

[0035] As a further improvement of the present invention, the control method further includes the following before S1:

[0036] S05. The safety layer ensures vehicle safety throughout the entire process:

[0037] Fail-safe design: Prioritize the shutdown of non-core systems to ensure basic driving capabilities and achieve gradual functional degradation; when all electronic systems fail, the vehicle automatically enters a safe crawl mode and automatically drives away from the danger zone at a speed of ≤5km / h to achieve a final safe state.

[0038] Furthermore, the present invention also solves the above problems through the following technical solutions:

[0039] A strong magnetic environment mode control system for a pure electric heavy-duty commercial vehicle is used to implement the strong magnetic environment mode control method for a pure electric heavy-duty commercial vehicle as described above. The system includes: a strong magnetic environment mode switch, a manual gear switch, a vehicle controller (VCU), a battery management system (BMS), an automatic mechanical transmission (AMT), and a CAN bus network connecting each controller.

[0040] The strong magnetic environment mode switch is located in the driver's cab and is used to send a trigger signal to the VCU to enter or exit the strong magnetic environment mode.

[0041] The manual gear switch, including separate D and R manual switches, is directly connected to the VCU's I / O port via hard wiring;

[0042] In normal mode, the vehicle operates according to its original logic, and the VCU communicates and coordinates with the BMS and AMT via the CAN bus. When the vehicle needs to enter a strong magnetic environment, the driver manually presses the "strong magnetic environment mode switch". This switch generates a hard-wired signal that is sent directly to the VCU. After receiving the signal, the VCU immediately switches from "normal mode" to "strong magnetic environment mode" and performs shielding operations and switches the transmission control.

[0043] Compared with the prior art, the present invention has the following advantages and beneficial effects:

[0044] (1) This invention determines whether the vehicle has entered a strong magnetic environment mode by using a strong magnetic environment mode switch. Based on the closed state of the D and R manual switches in the strong magnetic environment mode, the forward and reverse gears of the vehicle are changed. This invention adds a strong magnetic environment switch to ensure the adaptability of driving in special environments and the safety of the driver, and adds D and R manual switches to improve the vehicle's handling stability and shifting time performance in special environments, thereby increasing the vehicle's multi-functionality.

[0045] (2) This invention actively shields non-core fault signals that are susceptible to interference, avoiding misjudgments or functional chaos caused by a large number of "false alarms," ​​thus ensuring the stability of the control logic and the clarity of decision-making in harsh magnetic environments. It also simplifies the complex automatic shifting and pedal interlock logic into a direct manual switch operation, reducing the driver's operational burden and decision-making difficulty in emergency situations, resulting in rapid response and simple, reliable human-machine interaction. Through the environmental perception and prediction system, it can predict strong magnetic field threats in advance and automatically activate graded protection measures, upgrading the response strategy from "passive response" to "active defense," thus buying valuable time for vehicle and personnel safety.

[0046] Figure 1 This is a flowchart of a strong magnetic environment mode control method for a pure electric heavy-duty commercial vehicle according to the present invention. Detailed Implementation

[0047] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0048] Example 1:

[0049] Combined with appendix Figure 1 As shown, a control method for a pure electric heavy-duty commercial vehicle in a strong magnetic environment mode is described.

[0050] S1, Mode Trigger: The driver manually operates the strong magnetic environment switch. The vehicle enters the strong magnetic environment mode based on whether the strong magnetic environment switch is pressed. If the strong magnetic environment switch is not pressed, the normal driving procedure will run. If the strong magnetic environment switch is pressed, the vehicle will enter S2.

[0051] S2. Signal Processing and Shielding: Upon entering the strong magnetic environment mode, the vehicle control unit (VCU) sends a strong magnetic environment mode operation signal to the battery management system (BMS) via the CAN bus and performs the following shielding operations:

[0052] Shield the BMS from sending fault signals from current sensors, etc., to the CAN bus;

[0053] The VCU receives low-level alarm signals that are susceptible to interference and do not affect basic driving safety, such as some temperature sensor alarm signals, and no longer sends them to the CAN bus.

[0054] Optionally, a working signal value of 0 indicates normal mode; a working signal value of 1 indicates strong magnetic environment mode, to identify the mode of the working signal.

[0055] S3, Transmission control switch: The VCU stops sending upshift / downshift control commands to the automatic mechanical transmission (AMT), thus disabling the automatic shifting function of the AMT;

[0056] The vehicle no longer requires the brake pedal to be pressed for power-on / off and gear shifting. When the electronic switch malfunctions due to magnetic interference, the transmission gears can be directly controlled via physical buttons.

[0057] S4. Manual Gear Control: Activate the D (Forward) and R (Reverse) manual switches located in the driver's cab, independent of the original gear controller; the VCU directly receives the hard-wired signal from this manual switch and directly controls the vehicle gears based on its closed state.

[0058] When the D gear switch is closed and the R gear switch is open, the VCU controls the vehicle to enter D gear;

[0059] When the D gear switch is off and the R gear switch is on, the VCU controls the vehicle to enter R gear.

[0060] When the D and R switches are closed or open at the same time, the VCU controls the vehicle to enter N (neutral).

[0061] Specifically, in this embodiment, the VCU directly monitors the corresponding pins of D and R gears to obtain the current closed state of D and R gears.

[0062] S5. When the strong magnetic switch is disconnected, the vehicle's power on / off and gear shifting are restored to enable when the brake pedal is pressed, and the shielding operation in S2 is no longer performed.

[0063] In one specific embodiment, a strong magnetic environment mode control method for a pure electric heavy-duty commercial vehicle further includes, before the mode triggering step:

[0064] S01. Environmental Perception and Prediction:

[0065] Multiple magnetometer arrays are deployed around the vehicle to monitor the magnetic field strength of the surrounding environment in real time. Specifically, a nine-axis magnetometer array is placed at four key locations: the front and rear bumpers, the center of the chassis, and the top of the cab, forming a three-dimensional magnetic field monitoring network. Each nine-axis magnetometer array includes three Hall effect sensors for measuring low- to medium-intensity magnetic fields, three magnetoresistive sensors to extend the measurement range and accuracy, and three giant magnetoresistance sensors to detect high-intensity magnetic fields, achieving full-range coverage from 10 Gauss to 50,000 Gauss. All sensors employ differential measurement technology, automatically eliminating geomagnetic background interference by comparing data from adjacent sensors.

[0066] S02. Based on the monitored magnetic field strength, establish and update the digital twin model of the magnetic environment in real time to map the topological structure of the magnetic field where the vehicle is located.

[0067] S03. The LSTM neural network algorithm is used to predict the trend of magnetic field changes, and the corresponding graded protection strategy is triggered in advance based on the prediction results.

[0068] Preferably, the graded protection strategy includes at least:

[0069] (1) Three-level protection strategy to deal with different magnetic field strengths:

[0070] When the magnetic field strength is predicted or monitored to reach the first threshold of 500-1500 Gauss, Level I protection is activated, including initiating sensor redundancy verification and reducing the bus communication frequency.

[0071] When the magnetic field strength is predicted or monitored to reach the second threshold of 1500-3000 Gauss, Level II protection is activated, including the execution of "manual gear control" and "signal processing and shielding".

[0072] When the predicted or monitored magnetic field strength reaches the third threshold > 3000 Gauss, Level III protection is activated, including activating the fully mechanical backup control system and cutting off the power supply to magnetic field-sensitive electronic equipment.

[0073] (2) Signal transmission anti-interference:

[0074] Frequency hopping communication protocol: The VCU and the actuator adopt frequency adaptive switching, and automatically switch to the backup frequency band when encountering interference;

[0075] Peak-shifting time windows: Intelligent allocation of signal transmission periods for each controller to avoid electromagnetic resonance caused by concentrated transmission;

[0076] Quantum-encrypted transmission: Critical control commands are encrypted using quantum random numbers to prevent signals from being maliciously tampered with.

[0077] S04, Innovations in the Human-Computer Interaction Layer:

[0078] (1) Immersive state-aware interface;

[0079] The center console is equipped with a magnetic fluid display screen, which maintains stable display even in strong magnetic environments;

[0080] Achieve magnetic field visualization by visually displaying the distribution density of magnetic field lines through dynamic particle flow;

[0081] Haptic feedback steering wheel: Built-in magnetorheological fluid device provides different damping sensations according to the magnetic field strength.

[0082] (2) Multimodal backup:

[0083] Level 1 Backup: The D-gear manual switch and the R-gear manual switch are electronic rocker switches;

[0084] Secondary backup: A purely physical control mechanism that directly controls the gearbox gears via mechanical linkages and brass gears.

[0085] S05. The safety layer ensures vehicle safety throughout the entire process:

[0086] (1) Fail-safe design;

[0087] Gradual function degradation: Non-core systems are shut down first to ensure basic driving capabilities.

[0088] Final safety status: When all electronic systems fail, the vehicle automatically enters a safe crawl mode and automatically drives away from the danger zone at a speed of ≤5km / h.

[0089] (2) System self-healing ability;

[0090] The key circuit board uses a self-healing material, and microcracks can automatically heal within 24 hours.

[0091] The software system has incremental learning capabilities, optimizing its response strategy with each successful protection.

[0092] Example 2:

[0093] A strong magnetic environment mode control system for a pure electric heavy-duty commercial vehicle is used to implement the control method described in Example 1. The system mainly includes: a strong magnetic environment mode switch, a D gear manual switch, an R gear manual switch, a vehicle controller (VCU), a battery management system (BMS), an automatic mechanical transmission (AMT), and a CAN bus network connecting each controller.

[0094] The VCU is the control core of the system. In normal mode, the vehicle operates according to its original logic, and the VCU communicates and coordinates with the BMS, AMT, and other systems via the CAN bus.

[0095] When the vehicle needs to enter a strong magnetic environment, the driver manually presses the "Strong Magnetic Environment Mode Switch". This switch generates a hard-wired signal that is sent directly to the VCU. Upon receiving this signal, the VCU immediately switches from "Normal Mode" to "Strong Magnetic Environment Mode" and performs the following actions:

[0096] By sending a specific mode signal, such as a signal value of 1, to the BMS via the CAN bus, the BMS is notified to enter the strong magnetic field operating mode. Based on this, the BMS stops sending fault signals for current sensors susceptible to magnetic field interference to the CAN bus.

[0097] The VCU itself also stops processing and forwarding low-level, easily interfered-with alarm signals from temperature sensors and other sources that do not affect emergency driving.

[0098] The VCU stops sending any upshift or downshift commands to the AMT controller, and the AMT's automatic shifting function is suspended.

[0099] The VCU begins to continuously scan and read the hard-wired input status of the D and R manual switches.

[0100] The VCU disables the vehicle up / down high voltage logic and shift enable logic associated with the brake pedal sensor.

[0101] At this time, the vehicle's gears are entirely controlled by the D / R manual switches in the driver's cab. The driver operates these two switches, and the VCU directly controls the drive motor to output forward or reverse torque, or to shift into neutral, based on the combination of their "on" and "off" states, thereby enabling the vehicle to move forward, backward, or park.

[0102] Once the vehicle leaves the strong magnetic environment, the driver disconnects the "strong magnetic environment mode switch." Upon receiving the exit signal, the VCU fully restores all control logic under normal mode: CAN bus communication is restored, fault diagnosis and alarms are restored, AMT automatic shifting function is restored, and brake pedal interlock logic is restored, etc.

[0103] In an optional embodiment, specifically, the control system:

[0104] Strong magnetic environment mode switch: Located in the driver's cab, it is manually triggered by the driver to send a signal to the VCU to enter or exit the strong magnetic environment mode.

[0105] Manual gear shift switch: Includes independent D gear manual switch and R gear manual switch, which are directly connected to the VCU I / O port via hard wiring, and are used to send gear commands to the VCU in strong magnetic environment mode;

[0106] Vehicle Controller Unit (VCU): Configured to perform the following operations:

[0107] In response to the trigger signal of the strong magnetic environment mode switch, the strong magnetic environment mode control logic is entered;

[0108] In strong magnetic environment mode, generate and send instructions to mask specified fault and alarm signals;

[0109] Stop the automatic shift control of AMT;

[0110] The signal from the manual gear switch is collected and analyzed to directly control the direction of the vehicle's power output to achieve forward, reverse, or neutral.

[0111] In strong magnetic environment mode, the power-on / off and shift interlock logic related to the brake pedal is released.

[0112] Although the present invention has been described herein with reference to illustrative embodiments, the above embodiments are merely preferred embodiments of the present invention, and the implementation of the present invention is not limited to the above embodiments. It should be understood that those skilled in the art can devise many other modifications and implementations, which will fall within the scope and spirit of the principles disclosed in this application.
