[0001] This application relates to the field of vehicle control technology, and in particular to a special vehicle control system and method. Background Technology

[0002] With the rapid development of society and the economy, special vehicles are being used more and more widely in various fields, including fire trucks, ambulances, and engineering vehicles. These special vehicles are usually equipped with complex superstructures to meet the needs of specific tasks, such as lifting, fire fighting, and high-altitude operations. To achieve these functions, the superstructures of special vehicles typically require diverse styling variations and complex component movement control.

[0003] In the development of modern automotive technology, intelligence and automation are important directions. By adopting advanced control technologies, automated vehicle operation can be achieved, improving operational efficiency and safety.

[0004] Existing special vehicles use a single system to control the movement of related components. Because each component requires a separate control system, operators must manually operate the vehicle one by one when performing complex tasks. This method is not only time-consuming, but also increases the complexity of operation and the possibility of errors. Summary of the Invention

[0006] Specifically, this application is implemented through the following technical solution:

[0007] The first aspect of this application provides a special vehicle control system, the system comprising:

[0008] The vehicle controller is used to detect the operating status of the special vehicle and send the operating status to the central intelligent gateway;

[0009] The central intelligent gateway is used to send control commands to the electric cylinder controller based on the operating status; the control commands are determined according to a preset working mode, which specifically includes mode 1, mode 2, mode 3, mode 4 and mode 5, and the working mode is used to determine the working status of the vehicle.

[0010] The electric cylinder controller is used to control the electric cylinder motor to work based on the control commands; generate corresponding status signals according to the detected electric cylinder motor working mode and send them to the interactive network of the special vehicle; detect internal faults and generate fault signals; and generate hard-wired reset signals when communication failure occurs.

[0011] The electric cylinder controller is also used to feed back the operating mode of the electric cylinder motor, the status signal, and the fault signal to the IDS controller; the electric cylinder motor performs a hard-wired switch operation based on a hard-wired reset signal to control the initialization of the electric cylinder motor;

[0012] The IDS controller is used to control the electric cylinder controller based on the vehicle controller; it is also used to receive status signals from the electric cylinder controller through an interactive network, adjust the control strategy in real time according to the working status of the electric cylinder motor; and generate a reset signal based on the fault signal, and perform reset processing on the special vehicle based on the reset signal.

[0013] It also includes a smart surface, which is used to generate a reset signal based on the fault signal, so that the electric cylinder controller can reset the reset signal generated by the smart surface;

[0014] The electric cylinder controller is also used to detect internal faults. When a fault is detected, the execution process includes: determining whether it is a level 2 serious fault; if so, stopping the response to control commands and generating a fault signal; after receiving a reset signal from the IDS controller or smart surface, and detecting in real time whether the reset signal is responded to, processing is performed according to the response result. The processing method according to the response result is as follows: if responded to, the electric cylinder controller is controlled to return to the initial state; otherwise, the electric cylinder controller is returned to the initial state after the click control switch is manually turned on; if it is not a level 2 serious fault, and the electric cylinder continues to execute control commands, it is determined whether it is a level 1 minor fault; if so, the electric cylinder controller reports a system fault code; otherwise, the electric cylinder controller continues to work.

[0015] A second aspect of this application provides a method for controlling a special vehicle, the method comprising:

[0016] The system detects the operating status of special vehicles and sends the operating status to the central intelligent gateway.

[0020] The electric cylinder controller is controlled by the vehicle controller.

[0021] The special vehicle control system and method provided in this application detect the operating status of the special vehicle through the vehicle controller and send the operating status to the central intelligent gateway. The central intelligent gateway then sends control commands to the electric cylinder controller based on the operating status. The electric cylinder controller then controls the electric cylinder motor to operate based on the control commands.

[0029] This application provides a special vehicle control system and method for achieving fast and efficient vehicle control through vehicle interaction.

[0030] The special vehicle control system and method provided in this application detect the operating status of the special vehicle through the vehicle controller and send the operating status to the central intelligent gateway. The central intelligent gateway then sends control commands to the electric cylinder controller based on the operating status. The electric cylinder controller then controls the electric cylinder motor to operate based on the control commands. Furthermore, the special vehicle control system also feeds back the operating mode of the electric cylinder motor to the IDS controller through the electric cylinder controller, so that the IDS controller can control the electric cylinder controller based on the vehicle controller. In this way, when the vehicle controller ensures that the vehicle's operating status allows the electric cylinder motor to operate, the central intelligent gateway controls the electric cylinder controller to complete the control of the electric cylinder motor, realizing the control of the superstructure of the special vehicle. Furthermore, because the vehicle controller detects the vehicle's operating status, it ensures that the electric cylinder motor only starts when it is safe to do so. On the other hand, by comprehensively processing various signals through the central intelligent gateway, precise control of the electric cylinder controller can be achieved, ensuring the reliable operation of the electric cylinder controller. Furthermore, the operating mode of the electric cylinder motor is uploaded to the IDS controller, which allows for overall control of the electric cylinder controller and other components, thus fulfilling the vehicle-wide interaction requirements of special vehicles. In this way, the IDS controller can determine the operating mode of the electric cylinder within special vehicles, enabling complex and continuous vehicle-wide control.

[0031] The following specific embodiments are given to illustrate the technical solution of this application in detail.

[0032] Figure 1This is a schematic diagram of an embodiment of the special vehicle control system provided in this application. Please refer to... Figure 1 The system provided in this embodiment may include: a central intelligent gateway, an IDS controller, a vehicle controller, and an electric cylinder controller, wherein the vehicle controller is used to detect the operating status of the special vehicle and send the operating status to the central intelligent gateway;

[0033] The central intelligent gateway is used to send control commands to the electric cylinder controller based on the operating status; the control commands are determined according to a preset working mode, which specifically includes mode 1, mode 2, mode 3, mode 4 and mode 5, and the working mode is used to determine the working status of the vehicle.

[0034] The electric cylinder controller is used to control the electric cylinder motor to work based on the control commands; generate corresponding status signals according to the detected electric cylinder motor working mode and send them to the interactive network of the special vehicle; detect internal faults and generate fault signals; and generate hard-wired reset signals when communication failure occurs.

[0035] The electric cylinder controller is also used to feed back the operating mode of the electric cylinder motor, the status signal, and the fault signal to the IDS controller; the electric cylinder motor performs a hard-wired switch operation based on a hard-wired reset signal to control the initialization of the electric cylinder motor;

[0036] The IDS controller is used to control the electric cylinder controller based on the vehicle controller; it is also used to receive status signals from the electric cylinder controller through an interactive network, adjust the control strategy in real time according to the working status of the electric cylinder motor; and generate a reset signal based on the fault signal, and perform reset processing on the special vehicle based on the reset signal.

[0037] It also includes a smart surface, which is used to generate a reset signal based on the fault signal, so that the electric cylinder controller can reset the reset signal generated by the smart surface;

[0038] The electric cylinder controller is also used to detect internal faults. When a fault is detected, the execution process includes: determining whether it is a level 2 serious fault; if so, stopping the response to control commands and generating a fault signal; after receiving a reset signal from the IDS controller or smart surface, and detecting in real time whether the reset signal is responded to, processing is performed according to the response result. The processing method according to the response result is as follows: if responded to, the electric cylinder controller is controlled to return to the initial state; otherwise, the electric cylinder controller is returned to the initial state after the click control switch is manually turned on; if it is not a level 2 serious fault, and the electric cylinder continues to execute control commands, it is determined whether it is a level 1 minor fault; if so, the electric cylinder controller reports a system fault code; otherwise, the electric cylinder controller continues to work.

[0039] Specifically, the vehicle controller is a key electronic control unit in a vehicle, responsible for coordinating and managing the various subsystems of the vehicle. It should be noted that the vehicle controller can monitor the operating status of special vehicles in real time. For example, in one embodiment, the vehicle controller monitors the vehicle's speed, gear position, and handbrake status.

[0040] Furthermore, the vehicle controller monitors the vehicle's operating status to ensure that the vehicle is stationary before any changes to its shape are performed, preventing dangerous situations caused by alterations to the superstructure's shape before the vehicle has come to a complete stop.

[0041] In practice, when the vehicle controller detects that the vehicle speed is zero, the vehicle is in neutral, and the handbrake is released, it determines that the vehicle is stationary and sends this status to the central intelligent gateway.

[0042] Furthermore, the central intelligent gateway serves as the vehicle's communication hub, responsible for receiving and forwarding control signals from other vehicle systems. It ensures that instructions and feedback between different systems can be transmitted quickly and accurately.

[0043] Furthermore, the control commands are used to control the electric cylinder to operate in the corresponding working state. The specific data types included in the control commands are set according to actual needs, and are not limited in this embodiment. For example, in one embodiment, the control commands include mode 1, mode 2, mode 3, mode 4, and mode 5.

[0044] Furthermore, the control command can be issued based on the vehicle's remote control, the vehicle's smart surface, or the vehicle's IDS controller; this embodiment is not limited to any particular method. For example, in one embodiment, in conjunction with the above embodiments, when the driver determines that the vehicle needs to operate in mode 1, the control command "Mode 1" is issued.

[0045] In practice, when the central intelligent gateway determines that the vehicle is stationary, it sends control commands to the electric cylinder controller. It should be noted that deforming the vehicle body or superstructure while the vehicle is in motion could pose serious safety hazards. Therefore, issuing control commands based on the vehicle's operating status ensures the vehicle remains stationary, guaranteeing the safety of both the operator and the vehicle. Furthermore, performing shape-changing operations while the vehicle is stationary better suits practical operational needs and facilitates observation and adjustment by the operator.

[0046] Furthermore, after receiving a control command, the electric cylinder controller controls the electric cylinder motor to operate in the mode corresponding to the control command. For example, in one embodiment, referring to the example above, when the electric cylinder controller receives control command 1, it controls the electric cylinder motor to operate in mode 1.

[0047] It should be noted that after controlling the electric push cylinder motor to work, the electric push cylinder controller also detects the working mode of the electric push cylinder motor and feeds back the working mode to the IDS controller.

[0048] In this way, by detecting the operating mode of the electric cylinder controller, the current operating status and mode of the electric cylinder motor can be monitored in real time. This information is fed back to the IDS controller, which helps the IDS controller to fully understand the current changes in the vehicle's shape, thereby enabling more precise and coordinated control and decision-making. Furthermore, by feeding back the operating mode of the electric cylinder motor, the IDS controller can display this information on the intelligent operating surface or other human-machine interface, allowing operators to intuitively understand the current operating status of the electric cylinder, improving the transparency and convenience of operation.

[0049] Furthermore, Figure 2 This is a schematic diagram of Embodiment 2 of the special vehicle control system provided in this application. Please refer to... Figure 2 The IDS controller interacts with other components in the vehicle control system to jointly achieve intelligent control of special vehicles. Specifically, the IDS controller communicates with these components via CAN network signals to ensure the accurate transmission and execution of control commands.

[0050] It should be noted that the IDS controller may have intelligent decision-making and optimization capabilities. It can automatically select the most suitable control mode based on factors such as the vehicle's current status, driving environment, and user needs, and make fine adjustments and optimizations to the actions of the electric cylinder controller to improve the vehicle's handling and safety.

[0051] In practice, the IDS controller communicates with the vehicle controller to obtain the vehicle's operating status, which is then analyzed in conjunction with other systems. Based on the analysis results, the electric cylinder controller is controlled to ensure the stable operation of the vehicle.

[0052] The special vehicle control system and method provided in this application, based on the vehicle controller ensuring that the vehicle's operating state allows for the operation of the electric push cylinder motor, controls the electric push cylinder controller through a central intelligent gateway to achieve control of the special vehicle's superstructure. Furthermore, before the electric push cylinder controller executes control commands, the central intelligent gateway determines the vehicle's speed, gear position, and handbrake status to ensure the vehicle is in a safe and controllable stationary state before forwarding the control commands to the electric push cylinder. This coordination mechanism prevents external shape changes during vehicle movement or inappropriate conditions, improving system safety and stability.

[0053] Optionally, the electric cylinder controller is specifically used to detect the operating mode of the electric cylinder motor and generate a status signal to be sent to the interactive network of the special vehicle.

[0054] The IDS controller is specifically used to generate control signals based on the status signals in the interactive network.

[0055] Specifically, the specific type of the interaction network for special vehicles is set according to actual needs, and this embodiment does not limit it. For example, in one embodiment, the interaction network for special vehicles can be set as a CAN network.

[0056] Furthermore, the electric cylinder controller monitors the operating status of the electric cylinder motor in real time, including its current operating mode. Specifically, this can be achieved by reading sensor data or internal status information from the electric cylinder motor.

[0057] Furthermore, the electric push cylinder controller generates corresponding status signals based on the detected electric push cylinder motor operating mode, and uses these status signals to characterize the current operating state of the electric push cylinder motor.

[0058] Furthermore, the electric cylinder controller sends the generated status signals to other system components that require this information via the vehicle's interactive network.

[0059] Furthermore, the IDS controller receives status signals from the electric cylinder controller via an interactive network. It analyzes and processes these received status signals, generating corresponding control signals based on the analysis results. It should be noted that these control signals can be used to guide the next actions of the electric cylinder controller or other system components.

[0060] Furthermore, the IDS controller sends the generated control signals to the target system components via an interactive network to achieve precise control of the special vehicle's superstructure.

[0061] In this way, the electric cylinder controller detects the operating mode of the electric cylinder motor, generates a status signal, and sends it to the interactive network. This signal is then transmitted to the IDS controller, which generates control signals. Through close collaboration between the electric cylinder controller and the IDS controller, real-time information sharing and command transmission between system components are achieved, improving the overall coordination and response speed of the control system. Furthermore, the IDS controller can adjust the control strategy in real time based on the operating status of the electric cylinder motor, ensuring safe deformation operations of the superstructure under safe conditions, thereby enhancing operational safety. Moreover, the IDS controller can make intelligent decisions based on the operating status signals of the electric cylinder motor, optimizing the control strategy so that the special vehicle maintains optimal performance under various operating conditions.

[0062] Optionally, the special vehicle control system further includes a voice prompter and a smart surface; wherein the smart surface is used to generate and display visual prompts based on the status signals in the interactive network.

[0063] The voice prompter is used to generate and display auditory prompts based on the status signals in the interactive network.

[0064] Specifically, Figure 3 This is a schematic diagram of Embodiment 3 of the special vehicle control system provided in this application. Please refer to... Figure 3 The intelligent surface receives status signals from the electric cylinder controller through the special vehicle's interactive network.

[0065] Furthermore, the smart surface analyzes the received status signals to extract information related to the display. For example, in one embodiment, the smart surface analyzes and obtains information such as the operating mode and current status of the electric cylinder motor.

[0066] Furthermore, the smart surface generates corresponding visual cues. In practice, the visual cues on the smart surface may include flashing backlights on mode buttons, text or graphic prompts on the display screen, etc., to intuitively show the operator the working status of the electric cylinder motor.

[0067] It should be noted that, in one embodiment, after the electric cylinder controller completes the task corresponding to the control command, it sends a signal indicating the current mode status of the electric cylinder motor. At this time, the backlight of the corresponding working mode button and the non-adjacent working mode button on the smart surface turns off, while the adjacent mode button lights up. For example, if the motor is in mode 2, after the electric cylinder motor completes the work in mode 2, the backlights of the mode 2 and mode 4 buttons on the smart surface turn off, while the backlights of mode 1 and mode 3 lights up. This reduces the possibility of accidental touches by the operator and assists the operator in issuing subsequent control commands. It ensures the reliability and accuracy of control.

[0068] Furthermore, the voice prompt device receives status signals from the electric cylinder controller via the special vehicle's interactive network. It then parses the received status signals to extract information relevant to the display. Specifically, in one embodiment, the voice prompt device parses information such as the electric cylinder motor's operating mode and current status.

[0069] Furthermore, the voice prompt device generates corresponding auditory prompts based on the parsed status information. Specifically, in one embodiment, the auditory prompts generated by the voice prompt device can be voice announcements, alarm sounds, or other audio cues, used to provide auditory feedback to the operator.

[0070] The special vehicle control system provided in this embodiment displays visual cues through smart surfaces and auditory cues through voice prompts. This provides intuitive visual and auditory cues, enabling operators to more easily understand the operating status of the special vehicle control system. This helps reduce misoperation and improve operational efficiency. Furthermore, by providing real-time feedback on the system's operating status, the smart surfaces and voice prompts help operators promptly identify potential safety hazards and take appropriate measures. This helps ensure the safety of special vehicles during operation. Thus, by combining smart surfaces and voice prompts, operators can remotely control special vehicles, expanding the system's application scope and increasing its flexibility.

[0071] Optionally, the electric cylinder controller is also used to detect internal faults and generate fault signals;

[0072] The IDS controller is also used to generate a reset signal based on the fault signal, and to perform a reset process on the special vehicle based on the reset signal.

[0073] Specifically, the electric cylinder controller monitors the internal status and operating conditions of the electric cylinder motor in real time during the operation of the electric cylinder motor. When an abnormality or parameters that do not meet the normal operating standards are detected, the electric cylinder controller will identify it as an internal fault.

[0074] Optionally, the electric cylinder controller is also used to detect internal faults and generate fault signals;

[0075] The IDS controller is also used to receive a reset signal sent by the electric cylinder remote controller and perform a reset process on the special vehicle based on the reset signal.

[0076] Specifically, when an abnormal situation or parameters that do not meet normal operating standards are detected, the electric push cylinder controller will identify it as an internal fault. At this time, the electric push cylinder remote controller can be used to generate a reset signal to simplify the reset operation.

[0077] Optionally, the electric cylinder controller is also used to detect internal faults and generate fault signals;

[0078] The smart surface is also used to generate a reset signal based on the fault signal, so that the electric cylinder controller can perform reset processing on the reset signal generated by the smart surface.

[0079] Specifically, when abnormal conditions or parameters that do not meet normal working standards are detected, smart surfaces can be used to allow operators to remotely control special vehicles, expanding the application scope of the system and improving its flexibility.

[0080] Optionally, the electric cylinder controller is equipped with a motor control switch for the electric cylinder motor;

[0081] The electric push cylinder controller is also used to control the electric push cylinder motor to restart and restore it to the initial state position when it detects that the reset signal is not responded to and detects the restart operation of the motor control switch.

[0082] Specifically, the electric cylinder controller can detect internal faults independently. When a system fault is detected, it executes a protection strategy according to the set fault handling steps. In the case where the electric cylinder controller has a separate motor control switch, if the vehicle control and the electric cylinder controller fail to operate (e.g., the reset signals from the intelligent surface and IDS controller do not respond), the operator is provided with the ability to manually turn on the motor control switch, allowing the motor to return to its initial state. This achieves the purpose of providing a dual fault handling mechanism for the system of this application. Specifically, different reset signals can be assigned response priorities; the electric cylinder controller can prioritize responding to CAN signal resets, meaning the IDS intelligent driving system has a higher control priority.

[0083] Furthermore, when the electric cylinder controller confirms a fault, it generates a corresponding fault signal and sends this signal to the special vehicle's interactive network so that other system components can receive this information. For example, in one embodiment, when the electric cylinder motor unexpectedly stops operating, a motor fault is confirmed, and a fault code for the motor fault is sent to the interactive network.

[0084] Furthermore, the IDS intelligent driving system receives fault signals from the electric cylinder controller via an interactive network. In practice, the IDS intelligent driving system can analyze the received fault signals to determine the nature and severity of the fault.

[0085] Furthermore, based on the fault analysis results, the IDS intelligent driving system generates a reset signal and sends the reset signal to the system components that need to be reset through the interactive network.

[0086] Furthermore, upon receiving a reset signal, the electric cylinder controller and other related system components will perform a reset operation to restore the system to its initial or safe state.

[0087] The special vehicle control system provided in this embodiment, through real-time fault detection of the electric cylinder controller and the reset processing mechanism of the IDS intelligent driving system, can promptly detect and resolve system faults, preventing the escalation of faults and thus improving the reliability of the entire control system. Furthermore, upon detecting a fault, it can quickly respond and take measures to reset, ensuring that the special vehicle will not continue to perform dangerous operations under fault conditions, thus protecting the safety of operators and the vehicle. Moreover, through intelligent fault detection and reset processing, manual intervention and maintenance frequency can be reduced, lowering maintenance and labor costs.

[0088] Optionally, the electric cylinder controller is also used to generate a hard-wired reset signal in the event of a communication failure;

[0089] The electric push cylinder motor is also used to perform hard-wired switch operation to control the initialization of the electric push cylinder motor based on a hard-wired reset signal.

[0090] Specifically, the hardwire reset signal is a signal transmitted via hardwire. When the interactive network cannot complete the signal transmission normally, the hardwire reset signal is transmitted via hardwire.

[0091] Furthermore, regarding status monitoring: During normal operation, the smart surface monitors the communication status of the special vehicle's interactive network. When it detects that certain components are unable to communicate effectively, it determines that a hardwired reset is required to resolve the fault.

[0092] Furthermore, a hard-wired reset signal is generated by the smart surface. This signal is not transmitted through an interactive network, but is sent directly to the electric actuator motor via a hard wire (physical circuit). For example, in one embodiment, after a communication failure is detected, the operator manually generates a hard-wired reset signal through the electric actuator controller.

[0093] Furthermore, the electric push cylinder motor receives a hard-wired reset signal through a hard-wired interface. Upon receiving the hard-wired reset signal, the electric push cylinder motor is restored to its initial or safe state.

[0094] The special vehicle control system provided in this embodiment, by offering a hard-wired reset mechanism, enables the electric propulsion cylinder motor to be reset in the event of a communication failure, thereby enhancing the robustness and fault tolerance of the special vehicle control system. Furthermore, the hard-wired reset can quickly restore the special vehicle control system to a safe state, preventing potentially dangerous operations and ensuring the safety of operators and the vehicle. In this way, a single hard-wired switch provides dual protection after a fault occurs, improving the safety and reliability of the special vehicle control system.

[0095] Furthermore, the electric cylinder controller is also used to determine the fault level and generate a fault signal when the fault level is a predetermined level fault. The fault level is generally set to two levels. For example, if a level two fault is determined to be a severe level, the electric cylinder controller, upon detecting a fault, first determines whether it is a level two severe fault. If so, it stops responding to control commands and generates a fault signal. After receiving a reset signal from the IDS controller or smart display, it checks in real time whether the reset signal is responded to, and processes the response accordingly. If responded to, the electric cylinder controller is controlled to return to its initial state; otherwise, the control switch is manually turned on to manually restore the electric cylinder controller to its initial state. When the electric cylinder controller detects a fault that is not a level two severe fault, it checks whether the electric cylinder continues to execute control commands and determines whether it is a level one minor fault. If so, the electric cylinder controller reports a system fault code; otherwise, the electric cylinder controller continues to operate.
