AI Technical Summary
In existing technologies, adjusting the defrosting and defogging functions requires the driver to operate via buttons on the center console or the central control screen, which causes the driver's line of sight to deviate from the road ahead, increasing the risk to driving safety.
The system reuses the switch components (stalks, knobs, multiplex switches, etc.) of the wiper system to obtain signals from the air conditioning system and the wiper stalk switch, thereby realizing the adjustment of defrost and defogging airflow and intelligent switching of wiper control, avoiding the need for additional hardware.
No additional hardware is required. Drivers can adjust the air conditioning fan speed in the wiper control area while keeping their eyes focused on the road, reducing the time their eyes are off-target and enabling blind operation. This solves the safety problem of looking down to adjust the air conditioning and ensures functional safety.

Abstract
Description
Technical Field
[0001] This specification relates to the field of wiper control technology, and in particular to multiplexed wiper switch control methods, computer-readable storage media, and electronic devices. Background Technology
[0002] With the continuous improvement of vehicle electrification and intelligence, in-vehicle human-machine interfaces are undergoing a profound transformation from physical buttons to integrated screen operation. Against this backdrop, the defrosting and defogging system, as a key function to ensure driving visibility and safety, is also gradually shifting from traditional physical buttons on the center console to touch operation integrated into the central control screen.
[0003] Currently, in most vehicles, after the defrost and defog functions are activated, drivers still need to adjust the airflow via physical buttons on the center console or the corresponding interface on the central control screen. However, in real-world driving scenarios, the need for defrosting and defogging often arises during driving, and the airflow frequently needs to be dynamically adjusted based on the degree of fogging on the windows. If the driver must rely on center console buttons or navigate through multiple menus on the central control screen to make adjustments, their gaze will inevitably be diverted from the road for an extended period, significantly increasing driving safety risks. Summary of the Invention
[0004] This specification provides a method for reusing wiper switch control, a computer-readable storage medium, and an electronic device to partially solve the aforementioned problems existing in the prior art.
[0005] The following technical solution is adopted in this specification: This specification provides a control method for a multiplexed wiper switch, characterized in that the wiper system includes a wiper lever switch, a wiper, a multiplexed switch, and a rotary switch, comprising: S1. Acquire the operating mode signal of the air conditioning system, the gear position signal of the wiper lever switch, and the operation signal of the multiplex switch during the operation of the target vehicle; S2. Based on the gear position signal, select the corresponding wiper control strategy or airflow adjustment strategy: The gear position signal is always used to control the operation of the windshield wipers; the gear position signal includes specific control signals and multiplexed control signals. When the gear signal is a specific control signal and the air conditioning system is in defrost and defogging mode, the rotation signal of the rotary switch in the wiper system is continuously acquired, and the defrost and defogging airflow of the air conditioning system is controlled according to the rotation signal; wherein, the rotation signal represents the amount of rotation of the rotary switch, and the amount of rotation is positively correlated with the defrost and defogging airflow. When the gear position signal is a multiplexing control signal, the operation signal of the multiplexing switch continues to be monitored; based on the gear position signal and the operation signal of the multiplexing switch, the current function of the rotary switch is switched to wiper control, so that the wiper system controls the operation of the wipers according to the wiper control signal.
[0006] Based on the aforementioned technical methods, this solution eliminates the need for separate physical knobs or buttons for the defogging / defrosting function. It reuses existing wiper system switching components (lever, knob, multiplexed switch, etc.), reducing the number of switches near the center console or steering wheel. Functionality is expanded without adding new hardware, directly reusing existing components. When defogging / defrosting is needed, users can naturally adjust the air conditioning fan speed within the wiper operation area. Drivers do not need to look down for center console buttons or stare at the central screen; their gaze can remain focused on the road, significantly reducing time spent looking away and even enabling blind operation, completely resolving the core safety issue of "looking down to adjust." The control logic possesses conditional judgment capabilities, enabling intelligent switching between "different functions in different situations with the same hardware." Only under specific conditions (such as when the air conditioning is in defrost mode) does the knob control the fan speed; otherwise, it remains part of the wiper control, ensuring functional safety and preventing misoperation.
[0007] Furthermore, the specific control signal includes a signal characterizing that the wiper stalk switch is in the MIST position; The method further includes: sending a wiper point wiping operation control signal to the wiper system according to the gear position signal, until the gear position signal can no longer be obtained.
[0008] Further, the specific control signal includes a signal indicating that the wiper stalk switch is in the LOW position; The method further includes: sending a low-speed wiper control signal to the wiper system based on the gear position signal until the gear position signal can no longer be obtained.
[0009] Furthermore, the specific control signal includes a signal characterizing that the wiper stalk switch is in the HI position; The method further includes: sending a high-speed wiper operation control signal to the wiper system according to the gear position signal until the gear position signal can no longer be obtained.
[0010] Furthermore, the specific control signal includes a signal indicating that the wiper stalk switch is in the OFF position; The method further includes: sending a wiper control signal to the wiper system based on the gear position signal and the operation signal of the multiplexer switch, specifically including: When the gear position signal is a signal indicating that the wiper lever switch is in the OFF position, the long-time operation signal of the multiplex switch in the wiper system is continuously acquired. The long-time operation signal indicates that the user operates the multiplex switch for a period of time exceeding a preset time. Based on the gear position signal and the long-term operation signal, a wiper wash operation control signal is sent to the wiper system until the gear position signal can no longer be obtained.
[0011] Furthermore, the multiplexed control signal includes a signal indicating that the wiper stalk switch is in the INT / AUTO position; Based on the gear position signal and the operation signal of the multiplex switch, the current function of the rotary switch is switched to wiper control, so that the wiper system controls the operation of the wipers according to the wiper control signal, specifically including: Continue to acquire the no-operation signal of the multiplex switch in the wiper system; Based on the gear position signal and the no-operation signal, the operating mode of the wiper system is determined to be intermittent mode; In the intermittent mode, the operation signal of the multiplex switch is acquired again to determine the vehicle speed signal of the target vehicle, the rotation signal of the rotary switch, and the long-term operation signal of the multiplex switch, and the rotation amount of the rotary switch is determined based on the rotation signal of the rotary switch. The intermittent setting of the wiper system is determined based on the amount of rotation of the rotary switch; The wiper operating frequency is determined based on the vehicle speed signal and the intermittent gear. Based on the wiper operating frequency, a wiper intermittent operation control signal is sent to the wiper system until the gear signal can no longer be obtained.
[0012] Furthermore, the multiplexed control signal includes a signal indicating that the wiper stalk switch is in the INT / AUTO position; Switching the current function of the rotary switch to wiper control based on the gear position signal and the operation signal of the multiplex switch, so that the wiper system controls the wiper operation according to the wiper control signal, further includes: Continue to acquire the short-time operation signal of the multiplex switch in the wiper system, wherein the short-time operation signal represents the signal of the multiplex switch repeatedly operating a preset number of times within a preset time period; Based on the gear position signal and the short-time operation signal, the operating mode of the wiper system is determined to be automatic mode; In the automatic mode, the rotation signal of the rotary switch, the rainfall data of the rain sensor connected to the target vehicle, and the long-term operation signal of the multiplexer are determined, and the rotation amount of the rotary switch is determined based on the rotation signal of the rotary switch. The sensitivity of the wipers in the wiper system is determined based on the amount of rotation of the rotary switch. When the rainfall data reaches a preset threshold, an automatic wiper operation control signal is sent to the wiper system according to the wiper sensitivity until the gear signal can no longer be obtained; wherein, the automatic wiper operation control signal is used to control the wiper to operate automatically according to the sensitivity, and the sensitivity is proportional to the wiper operating speed.
[0013] Furthermore, the method also includes: in the intermittent mode or the automatic mode, acquiring the operation signal of the multiplex switch again to determine that the multiplex switch has no operation signal; When the air conditioning system is in defrost / defogging mode, the rotation signal of the rotary switch in the wiper system is continuously acquired, and the defrost / defogging air volume of the air conditioning system is controlled according to the rotation signal.
[0014] This specification provides a computer-readable storage medium storing a computer program that, when executed by a processor, implements the control method for a wiper switch that combines the wiper system and the defogger / defrost system.
[0015] This specification provides an electronic device, including a memory, a processor, and a computer program stored in the memory and executable on the processor, wherein when the processor executes the program, it implements a control method for multiplexing a wiper switch for both a wiper system and a defogger / defrost system.
[0016] The above-mentioned technical solutions adopted in this specification can achieve the following beneficial effects: This solution eliminates the need for separate physical knobs or buttons for the defrost / fog removal function. It reuses existing wiper system switching components (stalks, knobs, multiplexed switches, etc.), reducing the number of switches near the center console or steering wheel. Functionality is expanded without adding new hardware by directly reusing existing components. When defrosting / fogging is needed, users can naturally adjust the air conditioning fan speed within the wiper control area. Drivers no longer need to look down for center console buttons or stare at the central screen; their gaze can remain focused on the road, significantly reducing time spent looking away and even enabling blind operation, completely resolving the core safety concern of "looking down to adjust." The control logic has conditional judgment capabilities, enabling intelligent switching between different functions under different conditions using the same hardware. The knob only controls fan speed under specific conditions (such as when the air conditioning is in defrost mode); otherwise, it remains part of the wiper control, ensuring functional safety and preventing accidental operation.

Detailed Implementation
[0018] To make the objectives, technical solutions, and advantages of this specification clearer, the technical solutions of this specification will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this specification, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments in this specification without creative effort are within the scope of protection of this application.
[0019] In embodiments of this application, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element.
[0020] The technical solutions provided in the various embodiments of this specification are described in detail below with reference to the accompanying drawings.
[0021] Figure 1 A flowchart illustrating a control method for a multiplexed wiper switch provided in this specification includes the following steps: S1: Acquire the operating mode signal of the air conditioning system, the gear position signal of the wiper lever switch, and the operation signal of the multiplexer switch in the wiper system during the operation of the target vehicle.
[0022] This specification describes the process of controlling the wiper system and the defogging / defrosting system using a shared wiper switch. In the embodiments described herein, this process can be executed by a server. However, this specification does not limit the type of device or platform used to implement this control process. For example, a personal computer, mobile terminal, vehicle infotainment system, or an in-vehicle (or vehicle-mounted) Electronic Control Unit (ECU) can also be used. For ease of description, the Body Control Module (BCM) will be used as the execution entity in the following description.
[0023] In one or more embodiments of this specification, the wiper system includes a wiper stalk switch, a wiper blade, a multiplexer switch, and a rotary switch. The vehicle's body control unit is able to acquire the position signal of the wiper stalk switch in the wiper system during vehicle operation. Here, "during vehicle operation" refers to the vehicle being started and running, activated using the key, and in the KL15 ON state.
[0024] In the windshield wiper system, the wiper lever switch can be in the MIST, LOW, HI, INT / AUTO, and OFF positions. Therefore, this wiper system configuration is the same as that used in most vehicles currently, and is consistent with the wiper systems configured in most vehicles in the existing technology. Hence, the wiper system will not be described in detail.
[0025] Specifically, in this specification, the position signal of the wiper stalk switch is defined as including specific control signals and multiplexed control signals. The specific control signals include signals indicating that the wiper stalk switch is in the MIST position, signals indicating that the wiper stalk switch is in the LOW position, signals indicating that the wiper stalk switch is in the HI position, and signals indicating that the wiper stalk switch is in the OFF position. The multiplexed control signals include signals indicating that the wiper stalk switch is in the INT / AUTO position.
[0026] S2. Select the corresponding wiper control strategy or airflow adjustment strategy based on the gear signal.
[0027] In one or more embodiments of this specification, regardless of the operating mode of the air conditioning system, the body controller can control the operation of the wipers according to the gear signal of the wiper lever switch.
[0028] Specifically, such as Figure 2As shown, if the gear position signal indicates that the wiper stalk switch is in the MIST position, the vehicle controller sends a wiper spot wiping control signal to the wiper system based on the gear position signal until the gear position signal can no longer be obtained. Since the wiper stalk switch is in the MIST position at this time, it is in the wiper spot wiping mode. In this mode, when the user puts the wiper stalk switch in the MIST position, the wipers will start working at low speed. After the user releases the switch, the wiper stalk switch automatically returns to its original position and the wipers stop running. If the user pushes the wiper stalk switch only once, the wipers will only run at low speed once according to the low-speed operation control signal, then run once more, and stop after returning to the original position. It is worth noting that the operating frequencies of low-speed and high-speed wiper operation in this specification can be referenced from the low-speed and high-speed operation frequencies of existing vehicle wipers.
[0029] If the gear position signal indicates that the wiper lever switch is in the LOW position, the body controller sends a low-speed wiper operation control signal to the wiper system according to the gear position signal until the gear position signal can no longer be obtained. That is, when the wiper lever switch is not in the LOW position, the body controller can no longer detect the corresponding gear position signal and stops the low-speed wiper operation.
[0030] If the gear position signal indicates that the wiper lever switch is in the HI position, the body controller sends a high-speed wiper operation control signal to the wiper system according to the gear position signal until the gear position signal can no longer be obtained. That is, when the wiper lever switch is not in the HI position, the body controller can no longer detect the corresponding gear position signal and stops the high-speed wiper operation.
[0031] However, what's unique is that if the gear position signal indicates that the wiper stalk switch is in the OFF position, the vehicle controller, based on the gear position signal, needs to further obtain the long-duration operation signal of the multiplexer in the wiper system. This long-duration operation signal indicates that the user's operation of the multiplexer switch exceeds a preset time, such as the user pressing the multiplexer switch button for more than 3 seconds. The vehicle controller then sends a wiper washer operation control signal to the wiper system based on the gear position signal and the long-duration operation signal, entering washer mode. The wipers will then clear the windshield until the gear position signal can no longer be detected. That is, once the wiper stalk switch is no longer in the OFF position, the vehicle controller can no longer detect the corresponding gear position signal and stops washer operation. If the long-duration operation signal is not detected, washer mode is not entered.
[0032] Under the above four gear signal conditions (i.e., specific control signals), if the air conditioning system is operating in defrost / defogging mode, adjusting the rotation signal of the knob switch will control the defrost / defogging airflow of the air conditioning system. The rotation signal represents the amount of rotation of the knob switch, and this amount of rotation is positively correlated with the defrost / defogging airflow.
[0033] In one or more embodiments of this specification, if the gear position signal is a signal indicating that the wiper lever switch is in the INT / AUTO position, the body controller determines that the operating mode of the wiper system is intermittent mode based on the no-operation signal of the multiplex switch, which indicates that the user (such as the driver) has not operated the multiplex switch. That is, the wipers in the wiper system operate intermittently and repeatedly at certain intervals.
[0034] In the intermittent mode, the body controller receives the operation signal of the multiplex switch again. It's important to note that this operation signal determines whether the rotary switch is used to control the wipers. If the multiplex switch operation signal is a long-duration signal, it indicates that the rotary switch is used to control the wipers. If there is no multiplex switch operation signal, it means the rotary switch is still used to control the airflow.
[0035] The vehicle controller determines the target vehicle's speed signal and the rotary switch's rotation signal; these two signals are used to determine the wiper operating frequency. The vehicle speed signal characterizes the target vehicle's speed. The rotary switch's rotation signal characterizes the amount of rotation of the rotary switch. Therefore, based on the rotary switch's rotation signal, the amount of rotation of the rotary switch is determined. Then, based on the amount of rotation of the rotary switch, the intermittent setting of the wiper system is determined. For example, if the amount of rotation of the rotary switch is one-quarter of the maximum rotation range that the rotary switch can achieve, then the intermittent setting is identified as setting 1. This setting is incremented until 100% of the maximum rotation range is reached, at which point the intermittent setting is identified as setting 4.
[0036] The body controller sends an intermittent wiper operation control signal to the wiper system based on the wiper operating frequency. The wipers operate according to the wiper operating frequency until the system can no longer obtain a gear signal. That is, when the wiper lever switch is not in the INT / AUTO position, the body controller can no longer detect the corresponding gear signal and stops intermittent operation.
[0037] The table below is Table 1, which shows the frequency of windshield wiper operation.
[0038] Table 1. Wiper Operating Frequency Comparison Table
[0039] In one or more embodiments of this specification, if the gear position signal is a signal indicating that the wiper stalk switch is in the INT / AUTO position, the body controller determines that the wiper system's operating mode is automatic based on a short-time operation signal from the multiplexer switch, wherein the short-time operation signal indicates that the multiplexer switch is repeatedly operated a preset number of times within a preset time period, such as pressing the multiplexer switch twice within three seconds.
[0040] In the automatic mode, the body controller receives the operation signal from the multiplexer switch again. It's important to note that this multiplexer switch operation signal determines whether the rotary switch is used to control the wipers. If the multiplexer switch operation signal is a long-duration signal, it indicates that the rotary switch is used to control the wipers. If there is no multiplexer switch operation signal, it means that the rotary switch is still used to control the airflow.
[0041] After determining the long-term operation signal of the multiplexer switch, the body controller determines the rotation signal of the rotary switch and the rainfall data from the rain sensor connected to the target vehicle, and determines the amount of rotation of the rotary switch based on the rotation signal. The body controller then determines the sensitivity of the wiper system based on the amount of rotation of the rotary switch. When the rainfall data reaches a preset threshold, indicating rain has been detected, the body controller sends an automatic wiper operation control signal to the wiper system based on the wiper sensitivity, continuing until no gear signal can be obtained. The automatic wiper operation control signal controls the wipers to operate automatically according to the sensitivity, which is directly proportional to the wiper speed; higher sensitivity means more sensitive and faster wiping. In one or more embodiments of this specification, the above content is based on the wiper system being in non-maintenance mode.
[0042] based on Figure 1 The illustrated method of reusing the wiper switch control for both the wiper system and the defogging / defrosting system eliminates the need for separate physical knobs or buttons for defogging / defrosting functions. It reuses existing wiper system switch components (lever, knob, multiplexed switch, etc.), reducing the number of switches near the center console or steering wheel. This expands functionality without adding new hardware, directly reusing existing components. When defogging / defrosting is needed, users can naturally adjust the air conditioning fan speed within the wiper operation area. Drivers don't need to look down for center console buttons or stare at the central screen; their gaze can remain focused on the road, significantly reducing time spent looking away and even enabling blind operation, completely resolving the core safety issue of "looking down to adjust." The control logic has conditional judgment capabilities, enabling intelligent switching between "different functions in different situations with the same hardware." Only under specific conditions (such as when the air conditioning is in defrosting mode) does the knob control the fan speed; otherwise, it remains part of the wiper control, ensuring functional safety and preventing misoperation.
[0043] This specification also provides a computer-readable storage medium storing a computer program that can be used to execute the above-described... Figure 1 A control method for reusing wiper switches is provided.
[0044] This instruction manual also provides Figure 3 The diagram shows a schematic structural representation of the electronic device. Figure 2 As shown, at the hardware level, this electronic device includes a processor, internal bus, network interface, memory, and non-volatile memory, and may also include other hardware required for business operations. The processor reads the corresponding computer program from the non-volatile memory into memory and then runs it to achieve the above. Figure 1 A control method is provided that reuses a wiper switch for both the wiper system and the defrost / fog system.
[0045] Of course, in addition to software implementation, this specification does not exclude other implementation methods, such as logic devices or a combination of hardware and software. In other words, the execution subject of the following processing flow is not limited to each logic unit, but can also be hardware or logic devices.
[0046] In the 1990s, improvements to a technology could be clearly distinguished as either hardware improvements (e.g., improvements to the circuit structure of diodes, transistors, switches, etc.) or software improvements (improvements to the methodology). However, with technological advancements, many methodological improvements today can be considered direct improvements to the hardware circuit structure. Designers almost always obtain the corresponding hardware circuit structure by programming the improved methodology into the hardware circuit. Therefore, it cannot be said that a methodological improvement cannot be implemented using hardware physical modules. For example, a Programmable Logic Device (PLD) (such as a Field Programmable Gate Array (FPGA)) is such an integrated circuit whose logic function is determined by the user programming the device. Designers can program and "integrate" a digital system onto a PLD themselves, without needing chip manufacturers to design and manufacture dedicated integrated circuit chips. Furthermore, nowadays, instead of manually manufacturing integrated circuit chips, this programming is mostly implemented using "logic compiler" software. Similar to the software compiler used in program development, the original code before compilation must also be written in a specific programming language, called a Hardware Description Language (HDL). There are many HDLs, such as ABEL (Advanced Boolean Expression Language), AHDL (Altera Hardware Description Language), Confluence, CUPL (Cornell University Programming Language), HDCal, JHDL (Java Hardware Description Language), Lava, Lola, MyHDL, PALASM, and RHDL (Ruby Hardware Description Language). Currently, the most commonly used are VHDL (Very-High-Speed Integrated Circuit Hardware Description Language) and Verilog. Those skilled in the art should also understand that by simply performing some logic programming on the method flow using one of these hardware description languages and programming it into an integrated circuit, the hardware circuit implementing the logical method flow can be easily obtained.
[0047] The controller can be implemented in any suitable manner. For example, it can take the form of a microprocessor or processor and a computer-readable medium storing computer-readable program code (e.g., software or firmware) executable by the (micro)processor, logic gates, switches, application-specific integrated circuits (ASICs), programmable logic controllers, and embedded microcontrollers. Examples of controllers include, but are not limited to, the following microcontrollers: ARC 625D, Atmel AT91SAM, Microchip PIC18F26K20, and Silicon Labs C8051F320. A memory controller can also be implemented as part of the control logic of the memory. Those skilled in the art will also recognize that, in addition to implementing the controller in purely computer-readable program code form, the same functionality can be achieved by logically programming the method steps to make the controller take the form of logic gates, switches, application-specific integrated circuits, programmable logic controllers, and embedded microcontrollers. Therefore, such a controller can be considered a hardware component, and the means included therein for implementing various functions can also be considered as structures within the hardware component. Alternatively, the means for implementing various functions can be considered as both software modules implementing the method and structures within the hardware component.

[0049] For ease of description, the above devices are described in terms of function, divided into various units. Of course, in implementing this specification, the functions of each unit can be implemented in one or more software and / or hardware components.
