The term "and / or" used in this specification includes any and all combinations of one or more related listed items.
[0022] See also Figure 1 , Figure 1 1 is a schematic block diagram of a structure of a body control system provided by an embodiment of the present application. Figure 1 As shown, the upper load control system 100 includes: a lead vehicle central control module 10, a rear hanging control module 20 and a rear control handle 30, the rear hanging control module 20 is communicatively connected with the lead vehicle central control module 10 and the rear control handle 30, and the lead vehicle central control module 10 is also communicatively connected with the rear control handle 30.
[0023] The central control module 10 of the lead vehicle refers to a system that integrates multiple control units and software, and is used to manage and coordinate various functions of the vehicle. It is the core of the entire vehicle control, including hardware and software components such as the central processing unit, sensor interface, communication module, etc. Among them, the central control screen is a part of the central control module 10 of the lead vehicle, and is the interface for the driver to interact with the central control module 10 of the lead vehicle. Through the central control screen, the driver can view the vehicle status, receive information, and manually input instructions.
[0024] The rear-hook control module 20 refers to a system installed on the rear-hook that integrates multiple control units and software, and is used to manage and coordinate various functions of the rear-hook. Among them, the rear-hook control module 20 includes a rear-hook vehicle control unit 21 (rear-hook VCU, Vehicle Control Unit) and a display and control all-in-one unit 22. The functions of the rear-hook vehicle control unit 21 include: receiving and processing signals and data from the display and control all-in-one unit 22, sensors and other modules (for example, the central control module 10 of the lead vehicle); controlling the operation of the rear-hook, such as stirring, dumping and other mechanical actions; monitoring the status of the rear-hook and communicating with the lead vehicle to ensure real-time transmission and feedback of data; performing fault detection and safety management to ensure the reliable operation of the rear-hook system. The display and control all-in-one unit 22 is a device that integrates a display screen and control functions, usually installed on the rear-hook, providing the operator with a human-computer interaction interface. The functions of the integrated display and control unit 22 include: displaying the working status, parameters and warning information of the rear-hook, so as to facilitate real-time monitoring by the operator; receiving user input (such as touch or button operation), and converting these instructions into control signals and sending them to the rear-hook vehicle control unit 21; helping the operator understand the operation of the rear-hook through real-time feedback. In this embodiment, the rear-hook vehicle control unit 21 works closely with the integrated display and control unit 22. The integrated display and control unit provides the operation interface, and the rear-hook vehicle control unit 21 is responsible for execution and management functions, allowing the operator to interact with the rear-hook control module 20. These two components cooperate with each other to ensure the efficient and safe operation of the rear-hook.
[0025] The rear control handle 30 is a manual operating device for controlling the rear attachment, and is usually used to provide a backup control method when the display and control integrated unit 22 or the rear attachment vehicle control unit 21 fails. In this embodiment, the rear control handle 30 can be used not only to control the rear attachment control module 20, but also to control the lead vehicle central control module 10. The functions of the rear control handle 30 include: allowing the operator to directly manually control the various functions of the rear attachment or the lead vehicle, such as stirring, dumping, etc., to ensure that the operation can still be performed when there is a problem with the system; when the display and control integrated unit 22 or the lead vehicle central control module 10 loses communication or fails, the rear control handle 30 can quickly take over the control to ensure the continuity and safety of the operation. In addition, the rear control handle 30 is also equipped with a display screen, which can display the current upper load control status, so that the operator can operate accurately.
[0026] Specifically, the rear-mounted control module 20 is used to: obtain first hard-wire signal detection information; determine whether the lead vehicle and the rear-mounted vehicle comply with a first physical connection state based on the first hard-wire signal detection information; if they comply with the first physical connection state, obtain the communication status information of the lead vehicle, and switch the upper load control right based on the communication status information of the lead vehicle; if they do not comply with the first physical connection state, obtain the communication status information of the rear-mounted vehicle, and switch the upper load control right based on the communication status information of the rear-mounted vehicle.
[0027] In some embodiments, obtaining the first hard-wire signal detection information includes: sending a first hard-wire signal detection instruction to the lead vehicle central control module 10, so that the lead vehicle central control module 10 detects the physical connection status between the lead vehicle and the rear trailer according to the first hard-wire signal detection instruction, and returns the first hard-wire signal detection information to the rear trailer vehicle control unit 21.
[0028] It is understood that hard-wired signals refer to electrical signals transmitted through physical cables or connecting wires, which are usually used for various communication and control functions in vehicle systems. In actual working applications, hard-wired signals need to be transmitted through actual cables or connectors, which means that there is a physical connection between the two. This connection is direct and usually involves the transmission of current. In this embodiment, the rear-mounted vehicle control unit 21 needs to confirm the physical connection status between the head vehicle and the rear-mounted vehicle. To this end, the rear-mounted vehicle control unit 21 first generates a first hard-wired signal detection instruction, and the rear-mounted vehicle control unit 21 sends the instruction to the central control module 10 of the head vehicle. This process is usually carried out through a preset communication protocol (such as CAN bus). Secondly, after receiving the first hard-wired signal detection instruction, the central control module 10 of the head vehicle begins to parse the instruction, including identifying the type of instruction and execution requirements. Thirdly, the central control module 10 of the head vehicle performs corresponding detection operations according to the received instructions. This usually involves: checking whether the electrical signal of the hard-wired connection is normal (for example, whether there is a voltage signal); verifying the hardware status (such as whether the connector is reliable and whether the signal is stable). Then, after the detection is completed, the central control module 10 of the lead vehicle will generate the first hard-wire signal detection information, which usually contains detailed information on the connection status (such as "normal connection" or "failed connection"). The central control module 10 of the lead vehicle sends the detection information back to the control unit 21 of the rear vehicle, using the same communication protocol to ensure accurate transmission of the information. Finally, after receiving the first hard-wire signal detection information from the central control module 10 of the lead vehicle, the control unit 21 of the rear vehicle begins to parse and process the information. Based on the returned information, the control unit 21 of the rear vehicle takes subsequent measures (such as maintaining or switching control rights) as needed. This embodiment uses this process to ensure that the control unit 21 of the rear vehicle can understand the physical connection status between the lead vehicle and the rear vehicle in real time, discover problems in a timely manner and take corresponding measures to maintain the stability and safety of the system. In this way, the various modules of the vehicle can effectively collaborate to ensure smooth operation.
[0029] In some embodiments, if the first physical connection status is met, the communication status information of the lead vehicle is obtained, and the upper load control right is switched according to the communication status information of the lead vehicle, including: sending a first communication status detection instruction to the central control module of the lead vehicle to obtain the communication status information of the lead vehicle; when the communication status information of the lead vehicle returned by the central control module of the lead vehicle is not received within a preset time, it is determined that the communication status between the rear trailer and the lead vehicle is an interrupted state, and the upper load control right is switched to the rear control handle.
[0030] It is understandable that before performing the communication status detection, the system first confirms that the physical connection status between the rear trailer and the lead vehicle is normal, in order to ensure that subsequent communication operations will not fail due to physical connection problems. If the physical connection is normal, the rear trailer vehicle control unit 21 generates and sends a first communication status detection instruction to the lead vehicle central control module 10, the purpose of which is to request the lead vehicle central control module 10 to return the current communication status information. After receiving the communication status detection instruction, the lead vehicle central control module 10 evaluates its communication status (for example, whether it is working normally). This process may involve checking the internal communication module and status. The lead vehicle central control module 10 generates communication status information based on its status and sends it back to the rear trailer vehicle control unit 21. Among them, the communication status information may include states such as "connected (normal)" or "interrupted". After sending the request, the rear trailer vehicle control unit 21 sets a preset time (for example, the preset time is set to 15s) to wait for the response of the lead vehicle central control module. This mechanism ensures the response speed of the system. If the communication status information of the central control module 10 of the lead vehicle is not received within the preset time, the control unit 21 of the rear vehicle will determine that the communication status with the lead vehicle is interrupted. When the communication status is confirmed to be interrupted, the control unit 21 of the rear vehicle will switch the control right to the rear control handle, which ensures that the operator can continue to control the rear vehicle even if the communication of the lead vehicle fails.
[0031] In addition, when the communication status information of the lead vehicle returned by the central control module of the lead vehicle is received within a preset time, it is determined that the communication status information between the rear trailer and the lead vehicle is in a connected state, and the upper load control right is switched to the central control module of the lead vehicle.
[0032] It is understandable that after sending the communication status detection instruction, the rear-hook vehicle control unit 21 sets a preset time to wait for the response of the lead vehicle central control module 10. If the communication status information returned by the lead vehicle central control module is successfully received within the preset time, it means that the communication is normal. Once the communication status information is received, the rear-hook vehicle control unit 21 will confirm that the communication status between the rear-hook and the lead vehicle is a connected state based on the information, which means that the communication link between the two is normal and in an effective working state. According to the confirmed connection status, the rear-hook vehicle control unit 21 switches the upper control right to the lead vehicle central control module 10, which means that the operation of the rear-hook will be the responsibility of the lead vehicle central control module 10, and the operator can control it through the central control screen.
[0033] This embodiment realizes automatic control switching by real-time monitoring of the communication status between the lead vehicle and the rear trailer, so that the system can quickly respond to changes in communication conditions and enhance overall adaptability. Even if the communication between the lead vehicle and the rear trailer is interrupted, switching the control to the rear control handle can ensure that the operator can still manually control the rear trailer to avoid accidents. In addition, the operator can perform intuitive operations through the central control module of the lead vehicle, and in the event of a communication failure, the rear control handle is used as a backup control method, which not only improves the user experience, but also can quickly identify and respond to changes in communication status, reduce downtime caused by communication interruptions, and improve work efficiency.
[0034] In some embodiments, switching the control right of the upper equipment to the rear control handle includes: sending a control right switching instruction to the rear control handle, so that the rear control handle controls the upper equipment according to the control right switching instruction.
[0035] It is understandable that when the rear-mounted vehicle control unit 21 detects that the communication status with the lead vehicle is interrupted, it decides to switch the control of the upper load to the rear control handle 30. This is to ensure that in the event of a communication failure, the operator can still effectively control the functions of the rear load. First, the rear-mounted vehicle control unit 21 generates a control right switching instruction and sends the instruction to the rear control handle 30. This instruction clearly instructs the rear control handle 30 to take over the control of the upper load. After receiving the control right switching instruction, the rear control handle 30 will confirm the validity of the instruction and prepare to start controlling the operation of the upper load. According to the control right switching instruction, the rear control handle 30 can directly operate the upper load system, including performing functions such as stirring and dumping, which are usually performed through physical buttons or joysticks. In this embodiment, the mechanism of switching the control of the upper load to the rear control handle in the event of a communication interruption enhances the safety and continuity of the operation, while improving the flexibility of the system and the user experience.
[0036] In some embodiments, the rear suspension includes a rear suspension vehicle control unit and a display and control integrated unit; if the first physical connection state is not met, the communication state information of the rear suspension is obtained, and the upper body control right is switched according to the communication state information of the rear suspension, including: sending a second hard-wire signal detection instruction to the display and control integrated unit, so that the display and control integrated unit detects whether the rear suspension vehicle control unit and the display and control integrated unit meet the second physical connection state according to the second hard-wire signal detection instruction; if the second physical connection state is not met, the upper body control right is switched to the rear control handle; if the second physical connection state is met, a second communication state detection instruction is sent to the display and control integrated unit to obtain the communication state information of the display and control integrated unit, and the upper body control right is switched according to the communication state information of the display and control integrated unit.
[0037] It is understandable that the second hard-wire signal refers to a signal used to detect the physical connection status between the internal components of the rear suspension. It is usually transmitted through a dedicated signal line and can be a voltage signal or other forms of digital signals, which are used to confirm whether the connection between the two units is intact. The main function of this signal is to ensure that the physical connection between the rear suspension vehicle control unit 21 and the display and control integrated unit 22 is normal, so that subsequent communication and control operations can proceed smoothly. When it is detected that the lead vehicle and the rear suspension do not meet the first physical connection state (that is, the lead vehicle and the rear suspension are separated, and the rear suspension operates independently at this time), it will turn to obtain the communication status information of the rear suspension, which indicates that the physical connection between the rear suspension and the lead vehicle is unstable, so it is necessary to further confirm the status of each unit inside the rear suspension. The rear suspension vehicle control unit 21 will send a second hard-wire signal detection instruction to the display and control integrated unit 22. This instruction is used to allow the display and control integrated unit 22 to detect the physical connection state between it and the rear suspension vehicle control unit 21 (that is, the second physical connection state). If the display and control integrated unit 22 detects that the connection between it and the rear-hook vehicle control unit 21 does not conform to the second physical connection state, indicating that at this time both the lead vehicle central control module 10 and the display and control integrated unit 22 are in a state where they are unable to control the upper load, the rear-hook vehicle control unit 21 will switch the control of the upper load to the rear control handle 30, which ensures that the operator can continue to control the rear load and avoids operation interruption.
[0038] If the connection status is normal, the rear-mounted vehicle control unit 21 will send a second communication status detection instruction to the display and control integrated unit 22 to obtain its communication status information. According to the communication status information returned by the display and control integrated unit 22, the rear-mounted vehicle control unit 21 decides whether to continue to maintain the control of the upper load or switch back to other control methods (such as the central control module of the lead vehicle) again. Among them, the communication status information of the display and control integrated unit is obtained, and the control of the upper load is switched according to the communication status information of the display and control integrated unit, including: when the communication status information returned by the display and control integrated unit is not received within a preset time, it is determined that the communication status between the rear-control vehicle control unit and the display and control integrated unit is an interrupted state, and the control of the upper load is switched to the rear control handle; when the communication status information returned by the display and control integrated unit is received within a preset time, it is determined that the communication status information between the rear-control vehicle control unit and the display and control integrated unit is a connected state, and the control of the upper load is switched to the display and control integrated unit. It is understandable that after confirming that the physical connection between the display and control integrated unit 22 and the rear-mounted vehicle control unit 21 is in good condition, the rear-mounted vehicle control unit 21 will send a second communication status detection instruction to obtain the communication status information of the display and control integrated unit 22. Among them, the rear-mounted vehicle control unit 21 sets a preset time (for example, the preset time can be set to 10s) and waits for the response of the display and control integrated unit 22 during this time. If the communication status information of the display and control integrated unit 22 is not received within the preset time, the rear-mounted vehicle control unit 21 determines that the communication status between the rear-control vehicle control unit 21 and the display and control integrated unit 22 is an interrupted state. In this case, the upper control right will be switched to the rear control handle 30, allowing the operator to manually control the rear. If the communication status information of the display and control integrated unit 22 is successfully received within the preset time, the rear-mounted vehicle control unit 21 confirms that the communication status between the two is a connected state. At this time, the upper control right will be switched back to the display and control integrated unit 22, allowing operation through the display and control integrated unit 22. This embodiment realizes a dynamic switching mechanism of the upper control right by acquiring the communication status information of the integrated display and control unit, thereby ensuring the reliability, security and operation efficiency of the system.
[0039] In some embodiments, when the communication status information between the rear trailer and the lead vehicle is in a connected state, and the communication status information between the rear trailer vehicle control unit and the integrated display and control unit is in a connected state, the upper body is controlled by the lead vehicle central control module, the integrated display and control unit, or the rear control handle.
[0040] It is understandable that, under a specific communication state, the rear-hook vehicle control unit 21 will first confirm the following two conditions: the communication state between the rear-hook and the lead vehicle is in a connected state: this indicates that the communication between the lead vehicle and the rear-hook is normal and data exchange is possible; the communication state between the rear-hook vehicle control unit 21 and the integrated display and control unit 22 is also in a connected state: this indicates that the communication between the control unit inside the rear-hook and the integrated display and control unit is also normal. Once it is confirmed that both of the above conditions are met, it will be allowed to control the upper load by freely switching between three methods: the central control module 10 of the lead vehicle: the operator can operate through the central control screen of the lead vehicle to control various functions of the upper load; the integrated display and control unit 22: the operator can also control directly through the integrated display and control unit, which is suitable for scenarios where the rear-hook operates independently; the rear control handle 30: if the operator prefers manual control, the rear control handle can also be used to directly control the upper load. In specific communication situations, this embodiment provides flexibility for operators through a variety of control methods, and can select the most appropriate control method according to actual operation requirements, thereby enhancing operation efficiency, ensuring system reliability, optimizing user experience, and providing redundancy through a variety of control means. When a certain method fails, the operator can still control the upper device through other methods to ensure safe operation.
[0041] The embodiment of the present application provides a control system for upper load, which realizes accurate switching of the upper load control right under various communication states through communication interaction between the central control module of the lead vehicle, the rear-hook vehicle control unit of the rear-hook control module and the display and control integrated unit, and the rear control handle. In terms of communication mechanism, the system adopts a two-way communication method to ensure the rapid flow of information. The central control module of the lead vehicle can monitor the communication status between the rear-hook and the lead vehicle in real time, and once the communication is interrupted, it can automatically switch to the rear control handle for operation. This automatic switching mechanism greatly reduces the operation risk and ensures that the operator can react quickly and continue to control the upper load when encountering an emergency. In addition, the system takes into account a variety of communication states during design, including communication connection state, communication interruption state, physical connection and physical interruption state. Through real-time monitoring of these states, the system can switch the control right at the most appropriate time. For example, when the communication state between the rear-hook and the lead vehicle is in a connected state, and the communication state between the rear-hook vehicle control unit and the display and control integrated unit is also in a connected state, the system will allow control through the central control module of the lead vehicle, the display and control integrated unit or the rear control handle. This flexible control method allows operators to choose the best control method according to actual conditions, improving the flexibility of operation. Through this efficient communication interaction mechanism, the system shows obvious beneficial effects in many aspects: First, because the system can quickly switch control rights, operators do not have to frequently adjust the operation method when facing different communication states, thus saving time and improving overall operation efficiency. Second, the choice of multiple control methods allows operators to flexibly adjust the operation method according to task requirements. Whether it is controlled through the central control screen in the cab, directly using the display and control integrated machine at the rear hanging site, or manually operating the rear control handle, it can meet the needs of different occasions. Third, the system monitors the communication status in real time to ensure that a stable control chain can be maintained at any time. When the communication is interrupted, the automatic switch to the rear control handle can avoid accidental operations caused by communication failures and improve the safety of the system. Fourth, the integration of multiple control methods and the realization of the automatic switching mechanism make operators feel more convenient and comfortable during use, improving the overall user experience. Fifth: The real-time detection and rapid response mechanism reduces the operational risks caused by poor communication or physical connection problems, allowing operators to work in a safer environment.
[0042] The present application also provides a method for controlling a vehicle body, which is applied to the vehicle body control system 100 described above. Figure 2 , Figure 2 is a flow chart of the upper installation control method provided by the embodiment of the present application. Figure 2 As shown, the method includes:
