Description

Technical Field

[0001] The present application relates to the field of aircraft flight control technology, specifically to the field of fly-by-wire flight control technology, and further to an information prompt method and information prompt device for sidestick dual input and sidestick authority status. Background Art

[0002] As we all know, the flight control system is one of the core systems of modern aircraft. It is responsible for controlling the aircraft's attitude, direction, and flight status to ensure safe and stable flight. Depending on the control method, flight control systems can be divided into mechanical flight control systems, hydraulic flight control systems, and fly-by-wire flight control systems. Fly-by-wire flight control systems are widely used in modern civil and commercial aircraft. They control the aircraft by converting flight control commands into electrical signals.

[0003] Generally speaking, aircraft using fly-by-wire flight control systems typically use passive sidestick controllers (hereinafter referred to as sidesticks) on both sides of the cockpit as the primary control input for pitch and roll control. Specifically, a pair of sidesticks are used for input from the pilot and co-pilot, respectively. The pilot only needs to grasp the sidestick with one hand, and the pilot and co-pilot can operate the sidestick simultaneously. The actual command output is the algebraic superposition of the left and right sidestick inputs, but the command superposition value does not exceed the maximum value of a single sidestick input.

[0004] However, while algebraic superposition solves the problem of combining control inputs to a certain extent, in practice, the operation of a pair of sidesticks is relatively independent, and the drivers on either side cannot perceive the control inputs provided by the other side. Although the system processes the instructions through algebraic superposition, it can still cause misunderstandings, leading to uncoordinated operations and even operational errors. Moreover, simultaneous operation of the sidesticks may result in "conflicting" control commands from both sides, such as pushing the stick on one side while pulling the stick on the other side, which may cause the system to respond unexpectedly. Furthermore, in emergency situations, it is crucial to clearly define control priority.

[0005] Furthermore, when the pilot and copilot simultaneously operate the sidesticks but neither has priority control authority, a dual-input state occurs, potentially posing a hazard to the pilot and requiring an alert. According to the relevant regulations updated in various regions between 2010 and 2011, different levels of alerts have different visual cue color requirements. For example, a warning-level alert should use red; an alert-level alert should use yellow or amber; and an advisory-level alert should use any color other than red or green. Because dual-input alerts are warning-level alerts, red should be used.

[0006] The relevant models currently in mainstream operation in the civil aviation market use the sidestick authority indicator light installed on the visor in front of the pilot and co-pilot to indicate the sidestick priority control authority, but the dual input warning prompt cannot meet the latest relevant airworthiness requirements. Therefore, in order to meet the requirements of the 2010-2011 provisions, the current latest models mainly use the sidestick authority indicator light installed on the visor in front of the pilot and co-pilot to indicate the sidestick priority control authority, and use the primary flight display unit (PFD; Primary Flight Display) in the cockpit of the aircraft for dual input warnings. However, although this combination of PFD visual prompts and sidestick authority indicator lights can better prompt the crew of the sidestick authority status and sidestick dual input warnings, the combined visual prompt method has certain redundancy.

[0007] Furthermore, the symbols on traditional sidestick authority indicators are typically used to provide information about the other driver. This means that drivers cannot directly access their own information, only the other driver's. Training feedback shows that drivers often need a reaction time to confirm their current status, which makes initial learning difficult and hinders training. Furthermore, in actual operation, drivers prefer to understand their own status more than the other driver's. For example, after pressing the authority switch, if the red arrow indicating authority is not illuminated, they only know that the other driver has not obtained authority, but cannot determine whether they have actually obtained authority. Summary of the Invention

[0009] Therefore, the present application is formed to solve the above-mentioned technical problems, and its purpose is to provide an information prompting method and an information prompting device that can intuitively and concisely provide side stick status prompts.

[0010] Technical solutions used to solve technical problems

[0011] The present application provides an information prompt method for prompting the sidestick status during aircraft flight, comprising: judging whether one of the sidesticks has obtained priority control authority based on the operation status of each sidestick in the aircraft cockpit; when it is judged that one of the sidesticks has obtained priority control authority, displaying the authority identifier corresponding to the sidestick that has obtained priority control authority; and judging whether to display the prohibition identifier corresponding to the sidestick that has not obtained priority control authority based on the operation status of the sidestick that has not obtained priority control authority.

[0012] Preferably, when the authority selection device on each side stick is not operated, it is determined that no side stick has obtained priority control authority, so that the authority identification corresponding to each side stick is not displayed.

[0013] Preferably, when it is determined that no side stick has obtained priority control authority, it is determined whether it is in a side stick dual input state based on the operation status of each side stick. When at least two or more side sticks are operated simultaneously, it is determined that it is in the side stick dual input state, and the prohibition signs corresponding to the simultaneously operated side sticks are displayed respectively. When none of the side sticks are operated or only one side stick is operated, it is determined that it is not in the side stick dual input state, and the prohibition signs corresponding to the side sticks are not displayed.

[0014] Preferably, when the authority selection device on the side stick is operated, it is determined that the operated side stick obtains the priority control authority.

[0015] Preferably, when the authority selection devices on the side levers are operated successively, the side lever that is determined to be operated last obtains priority control authority.

[0028] Figure 3 An information display device according to another embodiment of the present application is shown. DETAILED DESCRIPTION

[0029] The present application is further described below in conjunction with the following embodiments. It should be understood that the following embodiments are only used to illustrate the present application and are not intended to limit the present application. The same or corresponding reference numerals in the figures represent the same components, and repeated descriptions are omitted. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0030] In the description of this application, it should be noted that the terms "first", "second" and "third" are used for descriptive purposes only and should not be understood as indicating or implying relative importance. The orientation or positional relationship indicated by the terms "center", "up", "down", "left", "right", "vertical", "horizontal", "inside" and "outside" are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this application and simplifying the description, and should not be understood as limiting this application. The terms "install", "connect" and "connect" should be understood in a broad sense. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0031] Below, refer to Figures 1 to 3, an information prompt device according to one embodiment of the present application is described. It should be understood that an aircraft cockpit typically has two pilots, the pilot and the co-pilot. Each pilot has an independently operable side stick and an independent information prompt device. Each pilot's side stick corresponds to the information prompt device on a one-to-one basis. The information prompt device displays the status of the side stick priority, i.e., the ownership of the control right.

[0032] Specifically, the pair of side sticks (not shown) are arranged on the outside of the seats of the pilot (captain) and the co-pilot. They are independent input devices and respectively include a side stick handle, a position sensor, a sensory force device, a centering device, a push-to-talk device, an authority selection device, etc. The pilot's operation of the push stick will generate corresponding operation signals. These operation signals are sent to the flight control system through the fly-by-wire flight control system to reflect the operating status of the side stick. For example, the position sensor will generate a position signal, the operation authority selection device will generate a priority control signal, and pushing and pulling the side stick in the forward, backward, left, and right directions will generate corresponding side stick control signals for controlling the pitch and roll of the aircraft, etc. As the operating status of the side stick, for example, the offset of the side stick, the moving speed and / or direction of the side stick, the current position and / or direction of the side stick, etc. may be included.

[0033] The authority selection device can be, for example, a priority button or a priority switch. As previously mentioned, when a pilot operates the authority selection device on the sidestick, a priority control signal is generated and transmitted to the flight control system. Upon receiving this signal, the flight control system assigns priority to the sidestick that performed the priority selection operation and cuts off the transmission of sidestick control signals to the sidestick that did not perform the priority selection operation. In other words, the sidestick that performed the operation receives sidestick priority control authority, meaning that no sidestick control signals for controlling the aircraft will be transmitted regardless of the operation of the sidestick that did not perform the priority selection operation.

[0034] As previously mentioned, a pair of information display devices are installed in front of the pilot and co-pilot seats, for example, on either side of the sunshade. The specific installation location is not limited, as long as it is convenient for the pilot to view at any time during operation. The corresponding information display devices for the pilot and co-pilot receive control signals from the aircraft control system to provide corresponding information displays.

[0035] like Figure 1As shown, the information prompting device includes a display unit and a control unit. The display unit has two indicator parts arranged on the left and right, which are used to display the permission sign and the prohibition sign respectively. The permission sign mentioned in this application is to prompt the driver that the side stick permission is obtained and the side stick permission is locked. The prohibition sign mentioned in this application means that the driver has operated the side stick when it should not be operated, resulting in the unintended activation of the side stick on his side. In other words, the prohibition sign prompts the driver to stop the side stick operation as soon as possible and reset it.

[0036] In this embodiment, the indicator portion is a pilot light and is symmetrically arranged as a green light and a red light. One indicator portion is green and illuminates to indicate a permission sign, while the other indicator portion is red and illuminates to indicate a prohibition sign. However, this is not limiting. For example, the green and red lights can be arranged in a vertically symmetrical manner, diagonally symmetrically, or asymmetrically, as long as it conforms to driver habits and complies with relevant regulations.

[0037] In addition, in the present embodiment, the indicator portion that is relatively close to the driver on the opposite side is red, and the indicator portion that is relatively far from the driver on the opposite side is green. However, it is not limited to this. For example, the indicator portions of the same color can all be set on the same side. Specifically, the indicator portions that are lit in red can all be set on the right side, and the indicator portions that are lit in green can all be set on the left side. This is acceptable as long as it conforms to the driver's habits and complies with relevant regulations.

[0038] In addition, in this embodiment, as the permission mark and the prohibition mark, the red light and the green light are used for prompting, but it is not limited thereto. For example, the information prompt device can be formed in the form of a text-type indication, specifically, Figure 3 As shown in the upper half of the figure, the ACT character on the left is lit in red as a prohibition mark, indicating that "the side stick on your side is not activated in advance", and the LOCK character on the right is lit in green as an authority mark, indicating that "the side stick authority is obtained and the side stick authority is locked". In addition, the information prompt device can also be formed in the form of a symbolic indication, specifically, as shown in the figure below: Figure 3 As shown in the lower half of the figure, as a prohibition sign, the "X" symbol on the left is lit in red, indicating that "the side stick on your side is unexpectedly activated". As an authority sign, the lock symbol on the right is lit in green, indicating that "the side stick authority is obtained and the side stick authority is locked."

[0039] The following, combined Figure 1 、 2 The prompting method of the information prompting device according to one embodiment of the present application is described. In addition, it should be clear that in the initial state, the information prompting device keeps the light off, that is, the logo is not displayed.

[0040] First, the control unit determines whether the driver or co-driver requests sidestick priority control authority. In other words, it determines whether one of the drivers has operated the authority selection device on the sidestick, that is, whether one of the drivers has obtained sidestick priority control authority. For example, the control unit can make this determination based on whether it receives a corresponding priority control signal.

[0041] If the control unit does not receive the priority control signal, indicating that neither pilot has operated the authority selection device on the sidestick, it is determined that no one has obtained sidestick priority control authority (i.e., no). In this case, the flight control system will not cut off the transmission of either pilot's sidestick control signal, that is, both pilots can control the aircraft using the sidestick.

[0042] Next, it is further determined whether the side stick dual input state is in effect, that is, whether the drivers on both sides are manipulating the side sticks simultaneously. For example, the determination can be made based on whether the side stick manipulation signals are received separately.

[0043] If the control unit does not receive the side stick manipulation signal or only receives the side stick manipulation signal from one side, it means that no one is manipulating the side stick or only one party is manipulating the side stick, then it is determined that there is no dual input (i.e., no), and a corresponding control signal is output to the display unit, such as Figure 1 Specifically, the green and red lights of both the pilot and co-pilot are off. The green light off indicates that the driver's side stick has no control priority, and the red light off indicates that the driver's side stick has not been "unintentionally activated."

[0044] If the control unit receives side stick control signals from both sides, indicating that the driver and co-pilot are operating the side sticks at the same time, it is determined that there is a double input (ie, yes), and outputs a corresponding control signal to the display unit, such as Figure 1 Specifically, the green light of both the driver and co-pilot is off and the red light is on. The green light off indicates that the driver's side stick has no control priority, and the red light on indicates that the driver's side stick is "unintended activation".

[0045] At this point, the sidestick is in a dual input state. As previously mentioned, dual input is a warning-level alert. This implementation uses a solid red light to provide a dual input warning, not only complying with international regulations but also omitting the PFD visual prompt compared to existing technologies, reducing unnecessary system redundancy.

[0046] If, while determining whether the pilot or co-pilot has requested sidestick priority, the control unit receives a priority control signal from one pilot, indicating that the pilot has operated the sidestick's authority selection device, the control unit determines that the pilot has obtained sidestick priority (i.e., "Yes"). Based on the priority control signal, the flight control system then cuts off transmission of the sidestick control signal from the pilot who has not received authority.

[0047] Next, the control unit further determines whether the other party is moving the sidestick, i.e., whether the driver who has not operated the authorization selection device is manipulating the sidestick (i.e., the sidestick operation status). For example, the control unit may make this determination based on whether it receives a sidestick manipulation signal (e.g., a deviation signal) from the other party.

[0048] If the control unit receives a side stick manipulation signal from the other party, indicating that the other party who has not obtained the authority is manipulating the side stick, it is determined that there is movement (ie, yes) and outputs a corresponding control signal to the display unit, such as Figure 1 The control display unit is shown in (c). Specifically, the green light of the party that has obtained the authority is always on and the red light is always off. The green light is on, indicating that the party's side stick has the control priority, and the red light is off, indicating that the party's side stick has not been "unexpectedly activated". The green light of the other party that has not obtained the authority is always off and the red light is always on. The green light is off, indicating that the party's side stick has no control priority, and the red light is on, indicating that the party's side stick has been "unexpectedly activated". At this time, since the flight control system has cut off the transmission of the side stick control signal of the other party that has not obtained the authority, even if the other party that has not obtained the authority operates the side stick, it cannot control the aircraft. The red light mainly serves as a reminder, that is, to remind the other party that has not obtained the authority to stop the operation (that is, a prohibition sign) to avoid accidentally causing the flight control system to produce unnecessary or inappropriate reactions.

[0049] If the control unit does not receive the side stick manipulation signal from the other party, it means that the other party who has not obtained the authority has not manipulated the side stick, and it is determined that there is no movement (ie, no).

[0050] Next, the control unit further determines whether the other party's side stick is in the neutral position, that is, whether the other party's side stick that has not obtained the authority has been reset. For example, the control unit can make the determination based on the position signal detected by the position sensor on the side stick.

[0051] If the control unit determines based on the position signal that the other party's side stick is not in the neutral position (ie, no), it outputs a corresponding control signal to the display unit, such as Figure 1The control display unit is shown in (c). Specifically, the green light of the party that has obtained the authority is always on and the red light is always off. The green light is on, indicating that the party's side stick has obtained the control priority, and the red light is off, indicating that the party's side stick has not been "unexpectedly activated". The green light of the other party that has not obtained the authority is always off and the red light is always on. The green light is off, indicating that the party's side stick has no control priority, and the red light is on, indicating that the party's side stick has been "unexpectedly activated". At this time, since the flight control system has cut off the transmission of the side stick control signal of the other party that has not obtained the authority, even if the side stick of the other party that has not obtained the authority is not in the neutral position, it will not affect the aircraft control. The red light mainly serves as a reminder (i.e., a prohibition sign), that is, to remind the other party that has not obtained the authority to reset the side stick to avoid accidentally causing the flight control system to produce unnecessary or inappropriate reactions. To further explain, resetting the side stick will inevitably cause the side stick to move, so the above judgment can be repeated.

[0052] If the control unit determines that the other side stick is in the neutral position (ie, it is) based on the position signal, it outputs a corresponding control signal to the display unit, such as Figure 1 Specifically, the green light of the party that has obtained the authority is always on and the red light is always off. The green light on indicates that the party's side stick has the control priority, and the red light off indicates that the party's side stick has not been "unexpectedly activated". The green and red lights of the other party that has not obtained the authority are always off. The green light off indicates that the party's side stick has no control priority, and the red light off indicates that the party's side stick has not been "unexpectedly activated".

[0053] If the control unit receives a priority control signal from one party in the dual input state of the side stick, it is determined that the party obtains the priority control authority. At this time, if Figure 2 If the process shown is in progress, interrupt the process and restart it after confirming the authority to obtain it. Figure 2 The process shown.

[0054] For example, in the above Figure 1 In the dual input state shown in (b), the left driver operates the authority selection device to obtain priority control authority and restart Figure 2 The process is shown. That is, if the right driver's side stick is not moved and is in the neutral position, the green light on the right driver's information display is constantly off and the red light is constantly off. If the right driver's side stick is moved or is not in the neutral position, the green light on the right driver's information display is constantly off and the red light is constantly on until the right driver's side stick is reset and no longer moves, and then the green light is constantly off. The green light on the left driver's information display is constantly on and the red light is constantly off.

[0055] If the control unit receives the priority control signal from one party and then receives the priority control signal from the other party, it is determined that the operation time of the latter party is the priority control authority. Figure 2If the process shown is in progress, interrupt the process and restart after changing the authority obtaining party. Figure 2 The process shown.

[0056] For example, in the above Figure 1 In the cases shown in (c) and (d), the left driver obtains priority control authority. Regardless of the side stick status of the right driver, as long as the right driver operates the authority selection device, the right driver obtains priority control authority and starts over. Figure 2 The process shown is as follows. That is, if the left driver's sidestick is not moved and is in the neutral position, the green light on the left driver's information display is constantly off and the red light is constantly off. If the left driver's sidestick is moved or is not in the neutral position, the green light on the left driver's information display is constantly off and the red light is constantly on until the left driver's sidestick is reset and no longer moves, and then the green light on the right driver's information display is constantly on and the red light (regardless of the previous state) is constantly off.

[0057] In addition, it should be made clear that for the above method, logical judgment and signal transmission can also be performed through other control systems such as flight control systems.

[0058] In summary, the information prompting device and information prompting method described in the present application can intuitively, clearly and in real time prompt the crew's sidestick input status, reduce the pilot's reaction time when identifying the status, and avoid the redundant display of the combination of PFD visual prompts and sidestick authority indicator lights, thereby increasing the integration of the cockpit display.

[0059] In detail, the information prompt device uses simple color blocks, graphics or characters to present the authority information and dual-input information that the pilot needs to know in a simpler and clearer visual prompting manner. This reduces the number of indicator lights and / or characters on the information prompt device, simplifies the prompting method, and makes the current authority status clear at a glance. The pilot can obtain the current sidestick authority status more quickly, which helps to reduce erroneous operations and improve flight efficiency.

[0060] Furthermore, the information prompt device's rational color layout not only complies with regulations for dual-input status warnings but also aligns with common sense in the field, allowing drivers to intuitively determine the current status instantly, further reducing the difficulty of processing information. For example, standard operations are colored green, while unauthorized or non-standard operations are colored red.

[0061] By replacing the "other party" status with the "own party" status, the driver can reduce guesswork about their current status and improve confirmation efficiency. For example, by displaying the permission indicator on the party that has obtained sidestick authority, the driver can clearly see whether they have obtained authority, without having to first determine whether the other party has obtained authority and then infer that they do not. Furthermore, by displaying the prohibition indicator on the party without sidestick authority, the driver can clearly, directly, and promptly inform the driver that their sidestick operation should be stopped and reset as soon as possible.

[0062] In addition, based on the above simple and intuitive visual prompts, drivers can quickly understand and master permission operations and status recognition, so that they can quickly adapt during training and shorten the entry time.
