Description

Technical Field

[0001] This invention relates to the field of bulldozer cab control technology, and more specifically, to a bulldozer cab control method and cab control system. Background Technology

[0002] High-horsepower bulldozers are core construction equipment in heavy-duty conditions such as mining and large-scale infrastructure projects. Their operational safety, efficiency, and human-machine collaboration directly affect project progress and operating costs. Currently, in the various systems of the high-horsepower bulldozer cab, the lighting system is controlled by multiple independent rocker switches, each directly connected to a corresponding relay via a dedicated wiring harness; the air conditioning system is equipped with an independent panel, connected to the blower, damper motor, and compressor controller via analog / digital dedicated lines; and the working mode settings rely on multi-level menu buttons on the main instrument panel, requiring users to navigate through layers on a monochrome or low-resolution LCD screen, resulting in a complex operation path and long visual movement.

[0003] Because the control devices of various systems in the cockpit are highly dispersed in the three-dimensional space of the cockpit, the driver needs to frequently shift his gaze and body movements in complex working conditions (such as heavy-load bulldozing at night and fine leveling on slopes), which can easily lead to distraction and increase the probability of safety accidents such as collisions and misoperation. Summary of the Invention

[0004] In view of this, the purpose of the present invention is to provide a bulldozer cab control method and a cab control system.

[0005] To achieve the above objectives, the technical solutions adopted in the embodiments of the present invention are as follows: In a first aspect, the present invention provides a bulldozer cab control method, applied to a cab control system, the cab control system comprising an integrated bus control panel, a power management module, controllers for multiple cab subsystems, and a CAN bus, wherein the integrated bus control panel, the power management module, and the controllers for the multiple cab subsystems are connected via the CAN bus, and the method comprises: The integrated bus control panel receives the scene mode command triggered by the driver and sends it to the power management module; The power management module generates a first control command corresponding to each cockpit subsystem based on the scene mode command and the pre-stored scene parameter configuration table, and sends it to the controller of each cockpit subsystem. The controller of each cockpit subsystem drives the target device of its respective cockpit subsystem to operate according to the corresponding first control command.

The target devices of the vehicle system are an engine and a hydraulic system. The step of generating a corresponding feedback message by the controller of each cockpit subsystem based on the operating status of the target device in its respective cockpit subsystem includes: The controller of the cockpit lighting system acquires the lighting status of the target lamp and the load current of the target lamp detected in real time by the current detection unit, and generates a feedback message. The controller of the cockpit air conditioning system acquires the air conditioning air temperature collected by the temperature sensor and the air conditioning air volume collected by the air volume sensor, and generates a feedback message. The controller of the vehicle system acquires the engine speed and the hydraulic pressure, and generates a feedback message.

[0009] Optionally, the cockpit control system further includes a main instrument cluster, which is connected to the power management module via a CAN bus. The integrated bus control panel has multiple function buttons. The method further includes: The power management module determines the execution status of each first control command based on the feedback messages sent by the controllers of each cockpit subsystem; when the execution status of any first control command is abnormal, it generates a diagnostic fault code and scenario mode status information and sends them to the integrated bus control panel and the main instrument panel. The integrated bus control panel divides the multiple function buttons into normal buttons and abnormal buttons according to the scene mode status information, and controls the backlight indicator of each normal button to light up and the backlight indicator of each abnormal button to flash. The main instrument displays the scene mode icon and the diagnostic fault code based on the scene mode status information.

[0010] Optionally, the cockpit control system further includes a central control instrument cluster, the central control instrument cluster and the controllers of the plurality of cockpit subsystems are connected via the CAN bus, and the method further includes: The controller of each cockpit subsystem will send a feedback message to the central control instrument; The central control instrument generates and displays a driving behavior report based on feedback messages sent by the controllers of each of the cockpit subsystems.

[0011] Optionally, the central control instrument is communicatively connected to an external terminal device, and the method further includes: The central control instrument panel sends the driving behavior report to the external terminal device so that the driver can view the driving behavior report through the external terminal device.

[0012] Optionally, the cockpit control system further includes a central control instrument cluster, the central control instrument cluster and the controllers of the plurality of cockpit subsystems are connected via the CAN bus, and the method further includes: When the central control instrument detects that the driver initiates an adjustment operation on the target cockpit subsystem through the control interface of the central control instrument, it generates a second control command and sends it to the controller of the target cockpit subsystem. The controller of the target cockpit subsystem adjusts the operating parameters of the target device of the target cockpit subsystem according to the second control command.

[0013] Optionally, the cockpit control system further includes a main instrument cluster, the main instrument cluster, the central control instrument cluster, and the controllers of the multiple cockpit subsystems are connected via the CAN bus, and the method further includes: The controller of the target cockpit subsystem generates a feedback message based on the operating status of the target device after adjusting the operating parameters in the target cockpit subsystem, and sends it to the main instrument.

[0014] Secondly, the present invention provides a cockpit control system, the cockpit control system including an integrated bus control panel, a power management module, controllers of multiple cockpit subsystems and a CAN bus, wherein the integrated bus control panel, the power management module and the controllers of multiple cockpit subsystems are connected through the CAN bus; The integrated bus control panel is used to receive scene mode commands triggered by the driver and send them to the power management module; The power management module is used to generate a first control command corresponding to each cockpit subsystem according to the scene mode command and the pre-stored scene parameter configuration table, and send it to the controller of each cockpit subsystem. The controller of each cockpit subsystem is used to drive the target device of the cockpit subsystem to operate according to the corresponding first control command.

[0015] The bulldozer cab control method and control system provided in this invention include an integrated bus control panel, a power management module, controllers for multiple cab subsystems, and a CAN bus. The integrated bus control panel, power management module, and controllers for multiple cab subsystems are connected via the CAN bus. The integrated bus control panel receives scene mode commands triggered by the driver and sends them to the power management module. The power management module generates a first control command corresponding to each cab subsystem based on the scene mode command and a pre-stored scene parameter configuration table, and sends it to the controller of each cab subsystem. Each cab subsystem controller drives the target device of its respective cab subsystem to operate according to the corresponding first control command. Because this invention constructs a control system including an integrated bus control panel, power management module, CAN bus, and multiple cab subsystem controllers, the driver only needs to press a button once to trigger scene mode selection, parse the pre-stored parameter configuration table, generate and distribute multiple first control commands, and drive the target devices of each cab subsystem to respond synchronously. This improves operational efficiency and safety while replacing point-to-point wiring harnesses with bus communication, reducing electrical failure rates and maintenance costs.

Detailed Implementation

[0019] 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. The components of the embodiments of the present invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0020] Therefore, the following detailed description of the embodiments of the invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the invention without inventive effort are within the scope of protection of the invention.

[0021] It should be noted that relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.

[0022] Currently, the cab controls of high-horsepower bulldozers are generally characterized by comprehensive functions but fragmented operation, complex wiring harnesses, and isolated systems: lights are controlled by multiple independent rocker switches, each directly connected to a relay via a thick bundle of wiring harnesses; air conditioning has a separate control panel installed on the other side of the dashboard; operating mode settings require navigating through pages on a small display screen; while various systems may have CAN bus connectivity, it is only used for limited status exchanges and cannot achieve deep collaboration. This situation results in physically dispersed control devices, requiring the driver to frequently move their eyes and arms in complex operating conditions, switching between multiple spatially separated control points, leading to a heavy operational burden and potential safety hazards due to distraction. Furthermore, each switch requires an independent wiring harness to connect to the actuator, resulting in extremely complex wiring harnesses within the cab, with hundreds of wires and connectors crammed into a small space. This not only significantly increases assembly difficulty, vehicle weight, and production costs but also introduces numerous potential failure points. Once a fault occurs, maintenance personnel must spend a considerable amount of time troubleshooting the wiring harness. In addition, traditional control is an open-loop method; for example, after toggling a light switch, it is impossible to confirm whether the light is actually on. This can lead to problems such as relay sticking or circuit breaks. When a light bulb burns out, the driver may not even notice until it affects operations or someone else points it out. This is particularly detrimental to construction machinery with high reliability requirements. More importantly, the lighting, air conditioning, and power systems operate independently and cannot automatically coordinate and optimize according to the actual working scenario. For example, when bulldozing at night, the work lights should be turned on simultaneously, the air conditioning should be recirculated, the engine torque and hydraulic sensitivity should be adjusted, and the instrument display should be switched. However, the driver still needs to manually operate each step, which is inefficient and makes it difficult to achieve the optimal configuration every time. Finally, the control logic is fixed in the hardware or non-upgradeable underlying software. Adding new functions or optimizing strategies often requires replacing hardware modules, which seriously restricts the product's ability to continuously evolve.

[0023] To overcome the shortcomings of the prior art, embodiments of the present invention provide a cockpit control system and a bulldozer cockpit control method applied to the cockpit control system, which will be described in detail below.

[0024] Please refer to Figure 1 This invention constructs a cockpit control system comprising an integrated bus control panel, a power management module, controllers for multiple cockpit subsystems, and a CAN bus, connecting the integrated bus control panel, power management module, and controllers for multiple cockpit subsystems via the CAN bus. The integrated bus control panel receives scene mode commands triggered by the driver and sends them to the power management module. The power management module then generates a first control command corresponding to each cockpit subsystem based on the scene mode command and a pre-stored scene parameter configuration table, and sends it to the controller of each cockpit subsystem. Finally, the controller of each cockpit subsystem drives the target devices of its respective cockpit subsystem according to the corresponding first control command, thereby fundamentally reconstructing the traditional bulldozer cockpit control method at three levels: physical structure, information interaction, and control logic.

[0025] Among them, multiple cockpit subsystems include at least a cockpit lighting system, a cockpit air conditioning system, and a vehicle system. The first control commands corresponding to the cockpit lighting system, the cockpit air conditioning system, and the vehicle system are respectively lighting control command, air conditioning control command, and vehicle control command. The target device of the cockpit lighting system is the target lamp, the target device of the cockpit air conditioning system is the air conditioner, and the target device of the vehicle system is the engine and hydraulic system.

[0026] The cockpit lighting system controller is used to control the power supply of the target lights according to the lighting control command; the cockpit air conditioning system controller is used to adjust the air conditioning parameters according to the air conditioning control command; the vehicle system controller is used to adjust the engine torque curve and the sensitivity of the hydraulic system according to the vehicle control command.

[0027] Meanwhile, the controller of each cockpit subsystem is also used to generate corresponding feedback messages based on the operating status of the target devices in its respective cockpit subsystem and return them to the power management module. Specifically, the controller of the cockpit lighting system is used to obtain the lamp status of the target lamp and the load current of the target lamp detected in real time by the current detection unit of the power management module, and generate feedback messages; the controller of the cockpit air conditioning system is used to obtain the air conditioning air temperature collected by the temperature sensor and the air conditioning air volume collected by the air volume sensor, and generate feedback messages; the controller of the vehicle system is used to obtain the engine speed and the hydraulic pressure, and generate feedback messages.

[0028] In embodiments of the present invention, such as Figure 2 As shown, the integrated bus control panel integrates touch-sensitive buttons for high beam, low beam, work lights, and turn signals, temperature / airflow / mode knobs and buttons, as well as one-button triggers for scene modes such as "heavy-duty bulldozing," "precision leveling," and "nighttime construction" into the same modular housing. It connects to the vehicle network via a standard CAN interface, completely eliminating the spatial dispersion of physical control points.

[0029] like Figure 3 As shown, the power management module no longer only undertakes the power distribution function, but also serves as the "decision center" of the intelligent cockpit. Its main control circuit is equipped with a high-performance automotive-grade microcontroller unit (MCU) and runs an embedded real-time operating system. Its communication interface includes at least two CAN interfaces, which can receive mode requests from the integrated bus control panel.

[0030] The scenario parameter configuration table is a software-defined data structure stored in the local memory of the power management module. For example, the "heavy load bulldozing mode" has a complete set of parameters such as the engine torque curve heavy load mode, hydraulic accelerator sensitivity adjustment value, air conditioning set to internal circulation + 22℃ + strong wind, front / rear work lights forced on, and instrument interface automatically switching to high-brightness work view.

[0031] The first control command is a standardized digital command generated by parsing the scene parameter configuration table. It corresponds to the lighting control command, air conditioning control command and vehicle control command respectively. Its content is defined by software parameters and supports over-the-air (OTA) remote upgrade without replacing any hardware.

[0032] After receiving the lighting control command, the cockpit lighting system controller drives the target lights to power on and illuminate them. It also monitors the load current in real time through the current detection unit integrated into the output port of the power management module to verify whether the lights are responding correctly. After receiving the air conditioning control command, the cockpit air conditioning system controller adjusts the air conditioning temperature setpoint, air volume, and operating mode. It also collects the actual air conditioning temperature and air volume through temperature and air volume sensors to form a verifiable closed loop. After receiving the vehicle control command, the vehicle system controller adjusts the torque mapping curve of the engine control unit (ECU) and sends sensitivity gain parameters to the hydraulic controller, thereby changing the action response speed and force of the hydraulic actuator.

[0033] All of the above actions rely on the CAN (Controller Area Network) bus to complete the command issuance and status feedback. As the "digital artery" for vehicle information transmission, this bus replaces the original hundreds of point-to-point wiring harnesses with a single communication link, which reduces wiring complexity and failure probability, and ensures the timing consistency and anti-interference capability of command transmission.

[0034] Understandably, the cockpit control system provided by this invention eliminates the operational inefficiency and safety hazards caused by the physical dispersion of control devices at the source. It replaces complex wiring harnesses with a single bus network, improving the reliability and maintainability of the electrical system. Through a closed-loop feedback mechanism, it ensures that the result of each operation is perceptible and verifiable, completely solving the operational uncertainty problem under traditional open-loop control. By using the power management module as a multi-source coordination hub, it achieves deep collaboration between previously isolated systems such as lighting, air conditioning, power, and instruments, enabling "one-click triggering" to truly have cross-system automatic adaptation capabilities. Furthermore, through a software-defined architecture, it endows the system with continuous evolution capabilities, significantly extending the product lifecycle.

[0035] Further, please refer to Figure 4 The cockpit control system also includes a main instrument cluster, which is connected to the power management module via a CAN bus. The power management module is also used to determine the execution status of each first control command based on the feedback messages sent by the controllers of each cockpit subsystem. When the execution status of any first control command is abnormal, it generates diagnostic fault codes and scenario mode status information and sends them to the integrated bus control panel and the main instrument cluster. The integrated bus control panel is also used to divide multiple function buttons into normal buttons and abnormal buttons according to scene mode status information, and control the backlight indicator of each normal button to light up and the backlight indicator of each abnormal button to flash.

[0036] The main instrument panel is used to display scene mode icons and diagnostic fault codes based on scene mode status information.

[0037] In embodiments of the present invention, such as Figure 5 As shown, the main instrument is equipped with a high-brightness TFT LCD screen, which is visible under strong light. Its internal main control chip integrates a graphics processing unit and is connected to the CAN bus through a standard CAN interface, which can receive and parse structured data from the power management module in real time.

[0038] Upon receiving feedback from the cockpit lighting system controller, the power management module extracts the target light's status and the load current value measured by the current detection unit. If the current value is zero or significantly deviates from the rated range, the lighting control command is deemed abnormal. Similarly, upon receiving feedback from the cockpit air conditioning system controller, it determines whether the air conditioning parameters meet the set values ​​based on the air conditioning temperature collected by the temperature sensor and the airflow collected by the airflow sensor. Upon receiving feedback from the vehicle system controller, it verifies whether the torque curve and sensitivity adjustment are effective by combining engine speed and hydraulic pressure data. If any judgment result is abnormal... Normally, the power management module generates diagnostic fault codes (DTCs) according to preset rules. These codes strictly follow industry standard formats and include fault type (e.g., "work light drive circuit open circuit"), location of occurrence (e.g., "power management module output port CH3"), and snapshots of key parameters (e.g., "measured auxiliary load current 0A, rated current 2.1A"). Simultaneously, it generates scene mode status information including the currently active scene name (e.g., "heavy load bulldozer mode"), abnormal subsystem identifier (e.g., "cabin lighting system"), and affected functional items (e.g., "front work lights"). The diagnostic fault codes and scene mode status information are synchronously broadcast to the integrated bus control panel and main instrument via the CAN bus.

[0039] The integrated bus control panel dynamically divides physical buttons into two categories based on scene mode status information: for functions that are performing normally (such as low beam headlights and air conditioning fan speed), the corresponding button backlight indicator is always on, indicating that the function is ready and the status is reliable; for functions that are performing abnormally (such as a certain working light malfunctioning), the corresponding button backlight indicator flashes at a preset frequency to form a conspicuous visual alarm.

[0040] The main instrument panel displays the diagnostic fault code in a "text and icon" format in the fault information area of ​​its display interface, and stably displays the "heavy load bulldozing" icon in the scene mode indicator area. This ensures that the driver can fully grasp the current scene operation integrity and specific fault location simply by looking up at the main instrument panel and looking down at the control panel without operating any interface.

[0041] Further, please refer to Figure 6The cockpit control system also includes a central control instrument cluster, which is connected to the controllers of multiple cockpit subsystems via a CAN bus. When the central control instrument cluster detects that the driver has initiated an adjustment operation targeting a specific cockpit subsystem through its control interface, it generates a second control command and sends it to the controller of the target cockpit subsystem. The controller of the target cockpit subsystem adjusts the operating parameters of the target devices within the target cockpit subsystem according to the second control command. The controller of the target cockpit subsystem also generates a feedback message based on the operating status of the target devices in the target cockpit subsystem after the adjustment of their operating parameters and sends it to the main instrument cluster. The main instrument cluster also displays the operating status of the target devices in the target cockpit subsystem after the adjustment of their operating parameters.

[0042] In embodiments of the present invention, such as Figure 7 As shown, the central control instrument uses a high-performance automotive-grade SoC, integrating the computing power of a neural network processing unit (NPU), and is equipped with a multi-touch capacitive screen. Its internal air conditioning control module provides an intuitive graphical interface, supporting independent, continuous, and stepless adjustment of the temperature, air volume, and air outlet mode of each temperature zone. Its internal panoramic imaging module receives raw video streams from four cameras, completes real-time stitching and distortion correction, and provides a 360° surround view. Its internal multimedia module supports Bluetooth music and local audio and video playback.

[0043] For example, the target cockpit subsystem can be the cockpit air conditioning system. When the driver adjusts the air conditioning temperature from 22°C to 24°C through the intuitive graphical interface provided by the air conditioning control module inside the central control instrument during operation of "heavy load bulldozer mode", the central control instrument immediately generates a second control command. The format of this command is independent of the first control command and does not trigger the BCM coordination process. Instead, it is sent directly to the air conditioning controller via the CAN bus. After receiving the second control command, the air conditioning controller bypasses the scene parameter configuration table and directly drives the compressor, blower, and damper motor to complete the temperature setpoint update and airflow adjustment. Matching and adjusting; at the same time, the air conditioning controller collects the air conditioning outlet temperature and actual air volume data in real time through the built-in temperature sensor and air volume sensor, and generates a structured feedback message by combining the current compressor speed, evaporator pressure and other operating parameters; this feedback message is no longer returned to the power management module, but is directly transmitted to the main instrument panel via the CAN bus; the main instrument panel displays "Air conditioning set temperature: 24℃", "Actual air outlet temperature: 23.6℃" and "Air volume level: 4 / 5" in real time in the vehicle status area in the form of dynamic values, while maintaining a stable display of the "Heavy load bulldozer" icon in the top scene mode indicator area.

[0044] Understandably, the embodiments of the present invention use the central control instrument as the autonomous adjustment entry point, the second control command as the dedicated communication channel, and the main instrument as the unified status exit point. While ensuring the stability of the scenario-based intelligent collaborative backbone, it empowers the driver with the ability to make real-time, accurate, and verifiable manual interventions on key subsystems (especially modules that directly affect comfort and perception, such as air conditioning, imaging, and multimedia), thereby improving the system's adaptability, inclusiveness, and humanization level in real and complex working environments.

[0045] Furthermore, the controller of each cockpit subsystem is also used to send feedback messages to the central control instrument; the central control instrument is used to generate and display driving behavior reports based on the feedback messages sent by the controller of each cockpit subsystem.

[0046] In a possible implementation, the central control instrument cluster can also communicate with external terminal devices to send driving behavior reports to the external terminal devices so that the driver can view the driving behavior reports through the external terminal devices.

[0047] Understandably, when the controller of the cockpit lighting system sends feedback messages containing the target light status and load current, the controller of the cockpit air conditioning system sends feedback messages containing air conditioning temperature and air volume, and the controller of the vehicle system sends feedback messages containing engine speed and hydraulic pressure, the central control instrument does not simply forward these messages. Instead, it performs time alignment, parameter correlation, and trend modeling on the multi-source messages based on a pre-set data statistical analysis module. For example, during "heavy-load bulldozing mode" operation, the system automatically identifies "the air conditioning temperature was manually increased by 2°C three times", "the hydraulic pressure peak reached 28MPa for 17 seconds", and "the work light load..." The current experienced two instantaneous drops between 12:03 and 12:05. These events were aggregated along a timeline to generate a structured driving behavior report. The report includes, but is not limited to, the cumulative usage time and percentage of each scenario mode, the frequency and timing of manual adjustments to the air conditioning / lights / instrument, the statistical mean and extreme values ​​of key parameters (such as average engine speed, hydraulic pressure fluctuation amplitude, and air conditioning temperature control deviation), and timestamps of abnormal events (such as the number of DTC triggers and periods of unresponsive commands). The driving behavior report is presented intuitively on the central control instrument touch screen in a combination of text and graphics, supporting swiping browsing, chart zooming, and highlighting of key indicators.

[0048] Meanwhile, the central control instrument establishes a secure communication connection with external terminal devices (such as the driver's smartphone, tablet, or fleet management platform) via Wi-Fi, Bluetooth, or 4G / 5G modules, and pushes the complete report to the device after encryption and packaging. The driver can view the fuel consumption distribution heat map, mode switching timeline, air conditioning adjustment behavior trajectory, and even receive optimization suggestions generated by the system based on historical data at any time in the mobile app.

[0049] The following is a detailed description of the bulldozer cockpit control method applied to the cockpit control system provided by the embodiments of the present invention.

[0050] Please refer to Figure 8 The bulldozer cab control method includes steps S101 to S103.

[0051] S101, the integrated bus control panel receives scene mode commands triggered by the driver and sends them to the power management module.

[0052] S102, the power management module generates the first control command corresponding to each cockpit subsystem based on the scenario mode command and the pre-stored scenario parameter configuration table, and sends it to the controller of each cockpit subsystem.

[0053] S103, the controller of each cockpit subsystem drives the target device of its respective cockpit subsystem to operate according to the corresponding first control command.

[0054] In a possible implementation, step S103 can be implemented as follows: the controller of the cockpit lighting system controls the power supply of the target lamp according to the lighting control command; the controller of the cockpit air conditioning system adjusts the air conditioning parameters according to the air conditioning control command; and the controller of the vehicle system adjusts the engine torque curve and the sensitivity of the hydraulic system according to the vehicle control command.

[0055] Furthermore, after step S103, the bulldozer cab control method may also include step S104.

[0056] S104, the controller of each cockpit subsystem generates a corresponding feedback message based on the operating status of the target device in its cockpit subsystem and returns it to the power management module.

[0057] In a possible implementation, step S104 can be implemented as follows: the controller of the cockpit lighting system obtains the lamp status of the target lamp and the load current of the target lamp detected in real time by the current detection unit of the power management module, and generates a feedback message; the controller of the cockpit air conditioning system obtains the air conditioning air temperature collected by the temperature sensor and the air conditioning air volume collected by the air volume sensor, and generates a feedback message; the controller of the vehicle system obtains the engine speed and the hydraulic pressure, and generates a feedback message.

[0058] Furthermore, after step S104, the bulldozer cab control method may also include steps S105 to S107.

[0059] S105, the power management module determines the execution status of each first control command based on the feedback messages sent by the controllers of each cockpit subsystem; when the execution status of any first control command is abnormal, it generates diagnostic fault codes and scenario mode status information and sends them to the integrated bus control panel and main instrument panel.

[0060] S106, the integrated bus control panel, divides multiple function buttons into normal buttons and abnormal buttons according to scene mode status information, and controls the backlight indicator of each normal button to light up and the backlight indicator of each abnormal button to flash.

[0061] S107, the main instrument panel displays the scene mode icon and diagnostic fault code based on the scene mode status information.

[0062] Furthermore, after step S104, the bulldozer cab control method may also include steps S108 to S110, which are parallel to steps S105 to S107.

[0063] S108, the controller of each cockpit subsystem sends feedback messages to the central control instrument.

[0064] S109, the central control instrument generates and displays a driving behavior report based on feedback messages sent by the controllers of each cockpit subsystem.

[0065] S110, the central control instrument panel sends the driving behavior report to an external terminal device so that the driver can view the driving behavior report through the external terminal device.

[0066] Furthermore, after step S103, the bulldozer cab control method may also include steps S111 to S114, which are parallel to step S104.

[0067] S111, when the central control instrument detects that the driver initiates an adjustment operation on the target cockpit subsystem through the control interface of the central control instrument, it generates a second control command and sends it to the controller of the target cockpit subsystem.

[0068] S112, the controller of the target cockpit subsystem adjusts the operating parameters of the target device of the target cockpit subsystem according to the second control command.
