Description

Technical Field

[0001] This application relates to the field of vehicle sunroof technology, and in particular to a control method, controller, vehicle, and medium for a double sunshade. Background Technology

[0002] With the development of automotive technology, modern cars are no longer just simple means of transportation, but intelligent mobile spaces with multiple functions. As one of the features that optimizes comfort, many vehicles are equipped with sunshades, which can control the brightness of the light inside the car by opening and closing them.

[0003] Current technologies typically use two physical buttons or voice / gesture controls to open and close sunshades. However, this approach results in high switch costs and a cramped switch layout inside the vehicle, and can lead to delayed sunshade opening and closing, resulting in a poor user experience. Therefore, improving the efficiency of switch operation is a pressing issue that needs to be addressed. Summary of the Invention

[0004] Therefore, it is necessary to provide a control method, controller, vehicle, and medium for dual sunshades to address the aforementioned technical problems, so as to realize the control of the opening and closing states of two independent sunshades by one switch, thereby improving the efficiency of switch use.

[0005] A first aspect of this application provides a method for controlling a double sunshade curtain, the method comprising:

[0006] The real-time position signal and switch action signal of the dual sunshade curtain are acquired. The switch action signal includes a combination signal of the open button and / or the close button. The open button and the close button respectively include short press, continuous short press and long press operation modes.

[0007] The opening and closing state of the double sunshade curtain is controlled based on the real-time position signal of the double sunshade curtain and the action signal of the switch.

[0008] A second aspect of this application provides a controller for implementing the control method for the double sunshade curtain described in the first aspect.

[0010] Fourthly, embodiments of the present invention provide a computer-readable storage medium storing a computer program, characterized in that the computer program, when executed by a processor, implements the control method for the dual sunshade curtain described in the first aspect.

[0011] In summary, this invention provides a control method, controller, vehicle, and medium for dual sunshades. By acquiring the real-time position signal of the dual sunshades and the action signal of the switch, wherein the switch action signal includes a combination signal of an open button and / or an close button, and the open and close buttons respectively include short press, continuous short press, and long press operation modes, the on / off state of the dual sunshades is controlled based on the real-time position signal of the dual sunshades and the switch action signal. Compared with traditional optimization methods, this application, by defining different switch operation modes (short press, continuous short press, or long press), enables one switch to control the on / off state of two independent sunshades, halving the arrangement of switches and wiring harnesses, reducing layout space, and significantly lowering costs, thereby improving the efficiency of switch use and providing a better user experience.

The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiments of the present invention.

[0025] To illustrate the technical solution of the present invention, specific embodiments are described below.

[0026] One embodiment of the present invention provides a control method for a double sunshade curtain, such as... Figure 1 The diagram shown is a flowchart of the control method for the double sunshade curtain. The control method for the double sunshade curtain can be implemented through the following steps.

[0027] S101: Obtain the real-time position signal and switch action signal of the dual sunshade curtain, wherein the switch action signal includes a combination signal of the open button and / or the close button, and the open button and the close button respectively include short press, continuous short press and long press operation modes.

[0028] In this embodiment, the dual sunshade curtains are an important component of the vehicle, used to block sunlight, provide greater privacy, and improve anti-theft capabilities. The control system of this application includes a physical contact switch, a motor Hall sensor, and an MCU controller. The physical contact switch controls the on / off state of the dual sunshade curtains, specifically configured as follows: Figure 2 As shown, since the switch includes two operation buttons, "on" and "off," and each button has three control modes: short press, consecutive short press, and long press, the switch's action signals include short press signals for the "on" button, consecutive short press signals for the "on" button, long press signals for the "on" button, short press signals for the "off" button, consecutive short press signals for the "off" button, or long press signals for the "off" button. A Hall sensor is used to detect the real-time position signal of the dual sunshades. This Hall sensor is built into the drive motor or integrated on the controller PCB board. The real-time position signal of the dual sunshades indicates their current degree of opening or closing: fully open (100%): the sunshade is fully raised; fully closed (0%): the sunshade is fully lowered; not fully open (1% - 99%): the sunshade is at a specific height, such as 50% indicating the sunshade is lowered to half its height. The MCU controller combines the input real-time position signal of the dual sunshades and the switch's action signal to make a judgment, thereby achieving one-button multi-function control, allowing one switch to control the on / off state of two independent sunshades.

[0029] It should be noted that the vehicles in this invention include, but are not limited to, small cars, compact cars, mid-size cars, and large-size cars, etc., and are not specifically limited in this invention.

[0030] In this embodiment of the invention, by acquiring the real-time position signal and the action signal of the switch of the double sunshade curtain, the subsequent switching state of the double sunshade curtain can be effectively controlled, thereby improving the overall efficiency of controlling the double sunshade curtain and ensuring the user's operating experience and comfort.

[0031] In this embodiment, the on and off buttons include short press, continuous short press, and long press operation modes, respectively. Predefined time thresholds are used to distinguish different action signals: Short press threshold (e.g., 45 seconds, 350 seconds): If the single press duration of the switch is greater than 45 seconds and less than 350 seconds, the action signal for this duration is considered a short press; Long press threshold (e.g., 350 seconds): If the long press duration of the switch is greater than 350 seconds, the action signal for this duration is considered a long press; Continuous short press threshold (e.g., 45 seconds, 350 seconds), and the number of continuous short presses must also be predefined (e.g., 3 times): If the continuous press duration of the switch is greater than 45 seconds and less than 350 seconds, and the number of consecutive button presses is less than or equal to 3, the action signal for this duration is considered a continuous short press. If this number of consecutive button presses is exceeded, the action signal is considered invalid. When the user presses the switch, the start time of the single press is recorded; when the user releases the button, the release time of the single press is recorded. By calculating the difference between these two time points, the single-press duration of the button can be obtained. The calculated single-press duration is compared with a preset time threshold to determine whether the action signal is a short press. When the user presses the switch, the start time of the long press is recorded, and when the user releases the button, the release time of the long press is recorded. By calculating the difference between these two time points, the long press duration of the button can be obtained. The calculated long press duration is compared with a preset time threshold to determine whether the action signal is a long press. When the user continuously presses the switch, the continuous press duration and the total duration of continuous presses are recorded. The continuous press duration and the total duration of continuous presses are compared with their corresponding preset time thresholds to determine whether the action signal is a series of short presses.

[0032] It should be noted that the predefined time threshold and predefined number threshold in the above embodiments can also be numerical values, and can be preset according to the vehicle situation. This application does not impose any limitations on this.

[0033] In this embodiment of the invention, by defining different switch operation methods (short press, continuous short press, or long press), one switch can control the on / off state of two independent sunshades, thereby halving the arrangement of switches and wiring harnesses, reducing the arrangement space and significantly reducing costs, improving the efficiency of switch use, and providing a better user experience.

[0034] S102: Control the opening and closing state of the double sunshade curtain according to the real-time position signal of the double sunshade curtain and the action signal of the switch.

[0035] In this embodiment, the dual sunshade curtain includes a main sunshade curtain and a secondary sunshade curtain. The main and secondary sunshade curtains are pre-set according to the user scenario, reflecting a difference in priority in responding to switch commands; this application does not impose any limitations on this. After acquiring the real-time position signal of the dual sunshade curtains and the switch action signal, the controller controls the opening and closing state of the dual sunshade curtains based on these signals.

[0036] As an optional embodiment, the opening and closing state of the double sunshade curtain is controlled based on the real-time position signal and the switching action signal, including:

[0037] When the real-time position signal indicates that both sunshades are closed, and the action signal of the switch is the first short press signal of the open button, then the main sunshade is controlled to open.

[0038] When the action signal of the switch is the second short press signal of the open button, if the main sunshade is not fully opened, the main sunshade is controlled to continue to open; if the main sunshade is fully opened, the secondary sunshade is controlled to open.

[0039] When the real-time position signal indicates that both sunshades are open, and the action signal of the switch is the first short press signal of the off button, then the main sunshade is controlled to close.

[0040] When the action signal of the switch is the second short press signal of the off button, if the main sunshade is not completely closed, the main sunshade is controlled to continue to close; if the main sunshade is completely closed, the secondary sunshade is controlled to close.

[0041] Specifically, a short press includes both initial and subsequent presses; this application will describe the first and second short presses. When the real-time position signal indicates that both sunshades are closed, and the switch's action signal is the first short press signal of the open button, the main sunshade is controlled to open. When the switch's action signal is the second short press signal of the open button, if the main sunshade is not fully open, it is controlled to continue opening; conversely, if the main sunshade is fully open, the secondary sunshade is controlled to open. When the real-time position signal indicates that both sunshades are open, and the switch's action signal is the first short press signal of the close button, the main sunshade is controlled to close. When the switch's action signal is the second short press signal of the close button, if the main sunshade is not fully closed, it is controlled to continue closing; conversely, if the main sunshade is fully closed, the secondary sunshade is controlled to close. It should be noted that the duration of a single button press must be greater than 45ms and less than 350ms to satisfy the short press signal control command.

[0042] As an optional embodiment, the opening and closing state of the double sunshade curtain is controlled based on the real-time position signal and the switching action signal, including:

[0043] When the real-time position signal indicates that both sunshades are not fully open, and the action signal of the switch is a series of short presses of the open button, then both sunshades are opened simultaneously.

[0044] When the real-time position signal indicates that both sunshades are not fully closed, and the switch action signal is a series of short presses of the off button, then both sunshades are closed simultaneously.

[0045] Specifically, when the real-time position signal indicates that both sunshades are either not fully open or closed, and the switch action signal is a series of short presses of the open button, then both sunshades will open simultaneously. Conversely, when the real-time position signal indicates that both sunshades are either not fully closed or open, and the switch action signal is a series of short presses of the close button, then both sunshades will close simultaneously. It should be noted that the continuous button press duration must be greater than 45ms, and the total continuous button press duration must be less than 350ms to satisfy the continuous short press signal control command; otherwise, it is an invalid signal for switch debouncing. Furthermore, the number of consecutive button presses must be less than or equal to 3; exceeding this number also results in an invalid signal.

[0046] As an optional embodiment, the opening and closing state of the double sunshade curtain is controlled based on the real-time position signal and the switching action signal, including:

[0047] When the real-time position signal indicates that the secondary sunshade is closed and the main sunshade is open, and the action signal of the switch is a long press signal of the off button, then the secondary sunshade is controlled to perform a re-initialization operation.

[0048] When the real-time location signal indicates that the secondary sunshade is open and the main sunshade is closed, and the action signal of the switch is a long press signal of the open button, then the secondary sunshade is controlled to perform a loss initialization operation.

[0049] When the real-time position signal indicates that the main sunshade is in the open state and the secondary sunshade is in the closed state, and the action signal of the switch is a long press signal of the off button, then the main sunshade is controlled to perform a re-initialization operation.

[0050] When the real-time location signal indicates that the secondary sunshade is closed, the primary sunshade is open, and the switch action signal is a long press signal of the open button, the primary sunshade is controlled to perform a loss initialization operation.

[0051] Specifically, lost initialization typically refers to a situation in a program or system where a variable, object, or resource was not correctly initialized before use, potentially leading to undefined behavior. Reinitialization refers to the process of reassigning a variable, object, or resource that has already been initialized to restore its state or update its content. This application controls the dual sunshade curtains to enable initialization adjustment. Specifically, when the real-time location signal indicates that the secondary sunshade is closed, the primary sunshade is open, and the switch action signal is a long press of the off button, and this condition is maintained for a preset duration, the secondary sunshade will be reinitialized. Similarly, when the real-time location signal indicates that the secondary sunshade is open, the primary sunshade is closed, and the switch action signal is a long press of the on button, and this condition is maintained for a preset duration, the secondary sunshade will undergo a loss initialization operation. Likewise, when the real-time location signal indicates that the secondary sunshade is open, the primary sunshade is closed, and the switch action signal is a long press of the off button, and this condition is maintained for a preset duration, the primary sunshade will undergo a reinitialization operation. Finally, when the real-time location signal indicates that the secondary sunshade is closed, the primary sunshade is open, and the switch action signal is a long press of the on button, and this condition is maintained for a preset duration, the primary sunshade will undergo a loss initialization operation. It should be noted that the long press time must be greater than 350ms to control the opening and closing of the dual sunshade and its initialization. The button will be released after the dual sunshade has completed its initialization to satisfy the long press signal control command; otherwise, it is an invalid signal and the dual sunshade will not perform the operation.

[0052] Furthermore, such as Figure 3 As shown, in this implementation, the secondary sunshade is the front sunshade, and the main sunshade is the rear sunshade. When either sunshade is running, if any other switch is given an action signal, both sunshades will stop operating. Furthermore, when the switch action signal is valid, its LIN signal switch input is invalid, and no control operation is performed. Except as defined below, other button methods for providing action signals are invalid, and both sunshades will not respond, as shown in the table below:

[0053]

[0054]

[0055] In this embodiment, the MCU (microcontroller unit) in the sunshade controller makes a combined judgment based on the input position status signals of the two sunshades and the action signal of the single physical switch, realizing one-button multi-function, one switch controls the on / off status of two independent sunshades, the arrangement of switches and wiring harnesses is halved, the arrangement space is reduced and the cost is significantly reduced, improving the efficiency of switch use and the overall efficiency of controlling the two sunshades.

[0056] In summary, this invention provides a control method, controller, vehicle, and medium for dual sunshades. By acquiring the real-time position signal of the dual sunshades and the action signal of the switch, wherein the switch action signal includes a combination signal of an open button and / or an close button, and the open and close buttons respectively include short press, continuous short press, and long press operation modes, the on / off state of the dual sunshades is controlled based on the real-time position signal of the dual sunshades and the switch action signal. Compared with traditional optimization methods, this application, by defining different switch operation modes (short press, continuous short press, or long press), enables one switch to control the on / off state of two independent sunshades, halving the arrangement of switches and wiring harnesses, reducing layout space, and significantly lowering costs, thereby improving the efficiency of switch use and providing a better user experience.

[0057] Figure 4 This is a schematic diagram illustrating the process executed by a controller according to an exemplary embodiment of this application, such as... Figure 4 As shown, a physical contact switch is installed on the vehicle to operate the opening and closing of the dual sunshades. A Hall sensor is installed on the motor controlling the dual sunshades to detect the real-time position signal of the dual sunshades. The real-time position signal of the dual sunshades and the action signal of the switch are input to the controller, so that the controller can combine the input position status signal of the dual sunshades and the action signal of the switch to make a judgment and output the operation process of the dual sunshades accordingly, so as to realize that one switch controls the opening and closing status of two independent sunshades. The process of the controller can be displayed on the host display. Since the switch includes two operation buttons, "on" and "off", and each button has three control modes: short press, continuous short press, and long press, the switch's action signals include a short press signal for the "on" button, a continuous short press signal for the "on" button, a long press signal for the "on" button, a short press signal for the "off" button, a continuous short press signal for the "off" button, or a long press signal for the "off" button. These signals are then combined with the real-time position of the double sunshade curtain to control its on / off state.

[0058] Therefore, it can be seen that after the physical switch is triggered, the controller receives the switch's action signal and simultaneously reads the real-time position signal of the dual sunshades (the Hall sensor's real-time position signal is also stored in the controller). Then, the controller in the dual sunshade control system, upon receiving the signals from the Hall sensor and the switch, combines the input dual sunshade position status signal and the switch's action signal to determine the opening and closing of the dual sunshades, thus outputting the corresponding sunshade operation process. This solution, without adding extra components, achieves the control of two independent sunshades with a single switch through a logical combination design of the dual sunshade positions, thereby improving the control efficiency of the sunshades and the efficiency of the switch, providing a better user experience, and has broad application prospects. It should be noted that this application does not impose any limitations on the relevant parameter settings.

[0059] Figure 5 This is a schematic block diagram illustrating a vehicle according to an exemplary embodiment of this application, such as... Figure 5 As shown, the vehicle includes a dual sunshade system and the controller described in the above embodiments, enabling the control method for the dual sunshades as described in the above embodiments. Given the aforementioned technical effects of the controller and the dual sunshade control method, the vehicle in this embodiment should also possess the same technical effects, which will not be elaborated further here.

[0060] In summary, the vehicle proposed in this application uses a controller to acquire real-time position signals and switch action signals (short press signals, consecutive short press signals, or long press signals of the open and / or close buttons) of the dual sunshades. Based on these signals, the controller controls the on / off state of the dual sunshades, enabling one switch to control the on / off state of two independent sunshades. This halves the number of switches and wiring harnesses, reduces space requirements, and significantly lowers costs, thereby improving the control efficiency of the sunshades and the efficiency of the switches, resulting in a better user experience.
