[0027] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the drawings of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0028] The present invention is described in detail below in conjunction with the accompanying drawings of the specification. The specific operating method in the method embodiment can also be applied to the device embodiment or the system embodiment. In the description of the present invention, unless otherwise specified, "at least one" includes one or more. "Multiple" refers to two or more. For example, at least one of A, B and C includes: A exists alone, B exists alone, A and B exist at the same time, A and C exist at the same time, B and C exist at the same time, and A, B and C exist at the same time. In the present invention, " / " means or, for example, A / B can mean A or B; "and / or" in this article is only a kind of association relationship that describes the associated objects, indicating that there can be three relationships. For example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone.

[0029] The present invention will be described in detail below in conjunction with specific implementation modes.

[0030] In practical applications, such as the Wuhan Optics Valley suspension vehicle, it is necessary to control the coupler to steer during the coupling rescue and subsequent uncoupling process to facilitate coupling operations in curved sections. However, the vehicle has no coupler controller and no external steering control knob. The network human-machine interface HMI (Human-Machine Interface) is required to issue instructions, and the central control unit CCU (Central Control Unit) controls the left turn, right turn, centering, and uncoupling solenoid valve actions of the coupler. In addition, according to the owner's operating habits and requirements, a single action command clicked on the HMI needs to control the actions of multiple coupler solenoid valves at the same time. Therefore, the coupler action requires a new logic to control.

[0031] In view of this, in some specific embodiments of the present invention, Figure 1 As shown, this solution provides a control method for steering a hook of a suspension vehicle, which is implemented by a vehicle central control unit CCU, and the method includes: Step 100, real-time detection of a coupler steering instruction sent by a human-machine interaction interface HMI, wherein the coupler steering instruction includes uncoupling, coupler left turn, coupler right turn and coupler centering; Step 200, in response to the coupler steering instruction, output corresponding coupler steering control logic according to the current vehicle condition; Step 300: Based on the coupler steering control logic, realize simultaneous control of multiple solenoid valves, wherein the solenoid valves include an unhooking solenoid valve, a left-turn solenoid valve, a right-turn solenoid valve, and a centering solenoid valve.

[0032] It should be noted that the existing suspension vehicle coupler steering control solution requires the use of a coupler controller or an external steering control knob, which is not suitable for vehicles without a coupler controller and an external steering control button, and cannot achieve simultaneous control of multiple coupler solenoid valves through a single action command based on the owner's operating habits and requirements.

[0033] Therefore, the present invention provides a control logic for a steerable coupler, which does not require an additional external rotation control knob. The coupler controller, on the existing network system architecture, issues a steering command by the human-machine interaction unit HMI of the network control and monitoring system, and the central control unit CCU controls the steering logic and sends the control command to the input and output module IOM, directly controls the relevant action solenoid valves, and realizes direct control of the coupler solenoid valve.

[0034] In some possible embodiments of the present invention, Figure 2 As shown, when the coupler steering instruction is to unhook, the coupler steering control logic includes: The driver's cab is occupied normally, the coupling power is closed, When HMI clicks on unhook, it outputs the unhook instruction; When HMI cancels the unhooking, the unhooking instruction is canceled; After the coupler is unhooked successfully, the middle cylinder is in the air supply state.

[0035] Specifically, this embodiment provides an implementation method for the steering control logic of the coupler during uncoupling. When the driver's cab occupancy signal and the coupling power closing signal are received at the same time, when the HMI clicks on uncoupling, the CCU outputs an uncoupling command. When the HMI cancels the uncoupling, the CCU cancels the uncoupling command, thereby realizing the steering control logic of the uncoupling command.

[0036] In some possible embodiments of the present invention, Figure 3 As shown, when the coupler steering instruction is for the coupler to turn left, the coupler steering control logic includes: When the coupler is operated to turn left, the left-turn solenoid valve is energized and actuated, while the center solenoid valve and the right-turn solenoid valve are not actuated; Setting condition: When the HMI clicks the coupler to turn left, the CCU outputs a left turn command; Reset condition: When the HMI clicks on the right turn, center, cancel action command or the linkage is in place, the CCU cancels the left turn command at the same time.

[0037] Specifically, this embodiment provides an implementation of the coupler steering control logic when the coupler turns left. When the coupler turns left, only the left turn solenoid valve is actuated, and the centering solenoid valve and the right turn solenoid valve are not actuated. During the execution of the coupler left turn instruction, when the user clicks on the right turn, centering, cancel action instruction or coupling in place action, the left turn instruction is canceled while the click action is executed, and the left turn action is stopped.

[0038] In some possible embodiments of the present invention, Figure 4 As shown, when the coupler steering instruction is for the coupler to turn right, the coupler steering control logic includes: When the coupler is operated to turn right once, the right turn solenoid valve is energized and actuated, while the centering solenoid valve and the left turn solenoid valve are not actuated; Setting condition: When the HMI clicks the coupler to turn right, the CCU outputs a right turn command; Reset condition: When the HMI clicks on the left turn, center, cancel action command or the linkage is in place, the CCU cancels the right turn command at the same time.

[0039] Specifically, this embodiment provides an implementation method of the coupler steering control logic when the coupler turns right. When the coupler turns right, only the right turn solenoid valve is actuated, and the centering solenoid valve and the left turn solenoid valve are not actuated. During the execution of the coupler right turn command, when the user clicks on the left turn, centering, cancel action command or coupling in place action, the right turn command is canceled while the click action is executed, and the right turn action is stopped.

[0040] In some possible embodiments of the present invention, Figure 5 As shown, when the coupler steering instruction is for the coupler to be centered, the coupler steering control logic includes: After one operation to center the coupler, the centering solenoid valve is energized and actuated, while the left-turn solenoid valve and the right-turn solenoid valve do not actuate. When it is not connected in place, the center solenoid valve is energized and actuated, while the left-turn solenoid valve and the right-turn solenoid valve are not actuated; When the coupling is in place, the center solenoid valve, the right turn solenoid valve, and the left turn solenoid valve do not operate; Positioning condition: HMI clicks the coupler to be centered or not in place; Reset conditions: HMI clicks to turn left, HMI clicks to turn right, the vehicle is coupled and in place, and the HMI is operated to cancel the action when there is no HMI centering signal.

[0041] Specifically, this embodiment provides an implementation method of the coupler steering control logic when the coupler is centered. When a signal that the coupler is centered or the vehicle is not in place is received, the centering solenoid valve is actuated, and the left turn solenoid valve and the right turn solenoid valve are not actuated. During the execution of the coupler centering instruction, when the user clicks on the left turn, right turn, in place action or a combined signal (cancel action instruction and no centering signal exist at the same time), the centering instruction is canceled while the click action is executed, and the centering action is stopped.

[0042] In some possible implementations of the present invention, the unhooking solenoid valve, the left-turn solenoid valve, and the right-turn solenoid valve perform an inflation action when energized, and the centering solenoid valve performs an inflation action when energized.

[0043] Through the above-mentioned coupler steering control logic, the present invention does not need to add an additional external rotation control knob. The coupler controller, on the existing network system architecture, sends a steering command by the network control and monitoring system human-machine interaction unit HMI, and the central control unit CCU controls the steering logic and sends the control command to the input and output module IOM to directly control the related action solenoid valve. The specific control logic can be summarized as follows: The solenoid valves for the coupler to turn left, turn right, center, and unhook will perform corresponding actions according to the actual operating requirements: Action 1: Unhooking: The coupler logic requires that the middle cylinder is in the air supply state after the coupler is uncoupled.

[0044] Action 2: Joint hanging: Coupler action 1: left turn of the coupler: When the coupler is operated to turn left once, the left turn solenoid valve is energized and actuated, while the center and right turn solenoid valves are not actuated.

[0045] Coupler action 2: coupler turns right: When the coupler is operated to turn right once, the right turn solenoid valve is energized and activated, while the center and left turn solenoid valves are not activated.

[0046] Coupler action 3, coupler in the center: Step 1: Operate the coupler to center once, the centering solenoid valve is energized and actuated, and the left and right turn solenoid valves are not actuated; Step 2: When the linkage is not in place, the center solenoid valve is energized and actuated, while the left and right solenoid valves are not actuated; Step 3: When the coupling is in place, the center, right turn and left turn solenoid valves will not work.

[0047] During this process, the unhooking, left turn and right turn solenoid valves are inflated when they are energized, and the centering solenoid valve is inflated when it is de-energized.

[0048] According to the actual needs of the vehicle, the present invention has newly designed the steering control logic of the suspension vehicle coupler when the vehicle rescue and other coupling needs are met, which better meets the needs of the owner and completes the simultaneous control of multiple solenoid valves when the coupler is turned left, centered, and right when the coupler is coupled.
