Technical Field
[0001] The present disclosure belongs to the field of automobile control technology, and in particular relates to a wiper control method, system, device and medium. Background Art
[0002] The rapid adoption of new energy vehicles in recent years has greatly facilitated daily travel and communication. Currently, windshield wipers are controlled by manually operating the shift position on the combination switch and the AUTO position (with a light rain sensor). These wipers are typically used in conditions with poor visibility, rain, or snow. Unexpected operating conditions can pose a safety hazard to drivers.
[0003] Therefore, it is necessary to provide a new wiper control method, system, device and medium to solve the above technical problems. Summary of the Invention
[0004] The purpose of the present disclosure is to provide a wiper control method, system, device and medium in order to solve the above problems.
[0005] The present disclosure achieves the above objectives through the following technical solutions: A wiper control method comprises the following steps: Select two positions on the steering wheel to input pressure, which are used to generate commands for controlling the wiper-wash linkage and the control point wipe / low speed and high speed operation respectively; The wipers are controlled by applying pressure equal to the entered value at the preset positions on the left and right sides of the steering wheel.
[0006] As a further optimization scheme of the present disclosure, the lower left position and the lower right position are selected on the steering wheel to enter pressure by hand. The pressure entered in the lower left position is used to generate instructions for controlling the wiper and washing linkage, and the pressure entered in the lower right position is used to generate instructions for controlling point scraping / low speed and high speed operation.
[0007] As a further optimization scheme of the present invention, when pressure is applied to the pressure monitoring area on the lower left part of the steering wheel, the pressure sensor recognizes the pressure and sends instructions to the body control module BDM for analysis and processing. The body control module BDM sends instructions to the relays of the wiper and washing system, the positive relay of the washing system is energized, and the wiper low-speed relay is energized. After spraying the washing liquid first, the wiper starts to wipe for a preset number of cycles and returns to the initial position.
[0008] As a further optimization scheme of the present invention, when pressure is applied to the pressure monitoring area on the lower right part of the steering wheel, the pressure sensor identifies the pressure size. If it is a point wiping command, the pressure sensor sends the command to the body control module BDM for analysis and processing, and then sends the command to the wiper low-speed relay. The positive pole of the wiper low-speed relay attracts the wiper for a preset number of times, and the body control module BDM sends a relay disconnect signal, and the wiper returns to its initial position.
[0009] As a further optimization solution of the present disclosure, when pressure is applied to the pressure monitoring area on the lower right side of the steering wheel, the pressure sensor identifies the pressure. If it is a low-speed wipe command, the pressure sensor sends the command to the body control module (BDM) for analysis and processing, and then sends the command to the wiper low-speed relay. The positive terminal of the wiper low-speed relay is energized, and the wiper starts working. When pressure is applied to the pressure monitoring area on the lower right side of the steering wheel again, the pressure sensor identifies the pressure. If it is a low-speed wipe command, the pressure sensor sends the command to the body control module (BDM) for analysis and processing, and then sends the command to the wiper low-speed relay. The positive pole of the wiper low-speed relay is disconnected, and the wipers return to their initial position. If no pressure is applied to the pressure monitoring area on the lower right side of the steering wheel again, but the body control module BDM recognizes the vehicle lock command, the body control module BDM sends a command to the wiper low-speed relay to disconnect the positive pole of the wiper low-speed relay and the wiper returns to its initial position.
[0010] As a further optimization solution of the present disclosure, when pressure is applied to the pressure monitoring area on the lower right side of the steering wheel, the pressure sensor identifies the pressure. If it is a high-speed wipe command, the pressure sensor sends the command to the body control module (BDM) for analysis and processing, and then sends the command to the wiper high-speed relay. The positive terminal of the wiper high-speed relay is energized, and the wiper starts working. When pressure is applied to the pressure monitoring area on the lower right side of the steering wheel again, the pressure sensor identifies the pressure. If it is a high-speed wiper command, the pressure sensor sends the command to the body control module (BDM) for analysis and processing, and then sends the command to the wiper high-speed relay. The positive pole of the wiper high-speed relay is disconnected, and the wipers return to their initial position. If no pressure is applied to the pressure monitoring area on the lower right side of the steering wheel again, but the body control module BDM recognizes the vehicle lock command, the body control module BDM sends a command to the wiper high-speed relay to disconnect the positive pole of the wiper high-speed relay and the wiper returns to its initial position.
[0011] A wiper control system, comprising: The command input module is used to select two positions on the steering wheel to input pressure, which are used to generate commands for controlling the wiper and wash linkage and control point wipe / low speed and high speed operation respectively; The wiper control module is used to control the wipers by applying pressure equal to the entered pressure value at preset positions on the left and right sides of the steering wheel.
[0012] As a further optimization solution of the present disclosure, the command input module selects two positions on the steering wheel to input pressure, which are used to generate the command for controlling the wiper and wash linkage and the command for controlling point scraping / low speed and high speed operation, respectively, including: Select the lower left and lower right positions on the steering wheel and enter the pressure with your hand. The pressure entered on the lower left is used to generate the command to control the wiper and wash linkage, and the pressure entered on the lower right is used to generate the command to control point scraping / low speed and high speed operation.
[0013] An electronic device comprises a processor, a communication interface, a memory and a communication bus, wherein the processor, the communication interface and the memory communicate with each other via the communication bus; Memory for storing computer programs; The processor is used to execute the program stored in the memory to implement the wiper control method.
[0014] A computer-readable storage medium stores a computer program, and when the computer program is executed by a processor, the wiper control method is implemented.

DETAILED DESCRIPTION
[0017] The present application will be described in further detail below in conjunction with the accompanying drawings. It is necessary to point out that the following specific implementation methods are only used to further illustrate the present application and cannot be understood as limiting the scope of protection of the present application. Technicians in this field can make some non-essential improvements and adjustments to the present application based on the above application content.
[0018] like Figure 1 As shown, a wiper control method includes the following steps: Select two positions on the steering wheel to input pressure, which are used to generate commands for controlling the wiper-wash linkage and the control point wipe / low speed and high speed operation respectively; The wipers are controlled by applying pressure equal to the entered value at the preset positions on the left and right sides of the steering wheel.
[0019] In this embodiment, it specifically includes: Pressure command input and recognition: Turn the gear on the combination switch to non-AUTO gear, open the central control screen, and find the pressure input command switch. Enter the pressure at a specific position on the left side of the steering wheel to control the wiper and wash linkage command. Enter the pressure value at a specific position on the right side of the steering wheel to control the spot wipe / low speed and high speed working commands respectively, such as Figure 2 shown.
[0020] Wiper and washer linkage working instructions: When the driver holds the pressure monitoring area on the left side of the steering wheel, the pressure sensor recognizes the pressure and sends a command to the BDM. After analysis and processing, the BDM sends a command to the wiper and washing system relays at the same time. The washing positive relay is energized, and the wiper low-speed relay is energized. After spraying the washing liquid, the wiper starts to wipe for 3 cycles and returns to the initial position. Figure 3 shown.
[0021] Wiper point wipe, low speed, high speed working instructions: When the driver holds the pressure monitoring area on the right side of the steering wheel, the pressure sensor identifies the pressure size. If it is a point wipe command, the pressure sensor sends the command to the BDM for analysis and processing, and then sends the command to the wiper low-speed relay. The positive pole of the wiper low-speed relay attracts the wiper blade once, and the BDM sends a relay disconnect signal, and the wiper returns to the initial position. Figure 4 shown.
[0022] When the driver holds the pressure monitoring area on the right side of the steering wheel, the pressure sensor identifies the pressure size. If it is a low-speed wiping command, the pressure sensor sends the command to the BDM for analysis and processing, and then sends the command to the wiper low-speed relay. The positive pole of the wiper low-speed relay is energized and starts working.
[0023] When the driver holds the pressure monitoring area on the right side of the steering wheel again, the pressure sensor recognizes the pressure size and identifies the pressure size as a low-speed wiper command. After sending the command to the BDM for analysis and processing, it sends the command to the wiper low-speed relay. The positive pole of the wiper low-speed relay is disconnected, and the wiper returns to its initial position. Figure 5 When the driver does not turn off the wipers, but the BDM recognizes the vehicle lock command, the BDM sends a command to the wiper low-speed relay, disconnecting the positive pole of the wiper low-speed relay and returning the wipers to their initial position, as shown in the figure. Figure 6 shown.
[0024] The high-speed wiper identification and processing method and the on / off control method are the same as those of the low-speed wiper. Specifically: When the driver holds the pressure monitoring area on the right side of the steering wheel, the pressure sensor identifies the pressure size. If it is a high-speed wiping command, the pressure sensor sends the command to the BDM for analysis and processing, and then sends the command to the wiper high-speed relay. The positive pole of the wiper high-speed relay is energized and starts working.
[0025] When the driver again grips the pressure monitoring area on the right side of the steering wheel, the pressure sensor detects the pressure as a high-speed wiper command, sends the command to the BDM for analysis and processing, and then sends the command to the wiper high-speed relay, which disconnects the positive terminal and returns the wipers to their initial position. If the driver does not turn off the wipers, but the BDM recognizes the vehicle lock command, the BDM sends a command to the wiper high-speed relay, disconnecting the positive terminal and returning the wipers to their initial position.
[0026] like Figure 7 As shown, an embodiment of the present disclosure provides a wiper control system, comprising: The command input module is used to select two positions on the steering wheel to input pressure, which are used to generate commands for controlling the wiper and wash linkage and control point wipe / low speed and high speed operation respectively; The wiper control module is used to control the wipers by applying pressure equal to the entered pressure value at preset positions on the left and right sides of the steering wheel.
