Description

Technical Field

[0001] This application relates to the field of windshield wipers, and more particularly to a windshield wiper system control method and a windshield wiper system control device. Background Technology

[0002] Currently, automatic wiper speed control and operation on the market require users to first adjust the wiper handle to AUTO mode (automatic mode), and then adjust the wiper speed using the automatic wiper "sensitivity" knob or toggle. Generally, the AUTO mode and the "sensitivity" knob or toggle are located on different knobs or switches, and sometimes the car's touchscreen is used instead of the knob.

[0003] Because in-vehicle touchscreens often have multiple layers of menu options and buttons, operating them requires the driver's line of sight and attention, which is detrimental to safe driving. Traditional manual buttons, knobs, or toggle switches require selecting the AUTO mode on one terminal and then switching to another to select the gear selector or switch. This inability to complete all operations on a single terminal is inefficient in terms of developing muscle memory and managing driver attention.

[0004] Because of the addition of more gear switches and their distribution in multiple locations, traditional wiper systems require the wiring harness to be guided to multiple terminal locations, which increases assembly complexity and material costs.

[0005] Therefore, a solution is needed that would facilitate blind operation of the windshield wiper system to address the issue of adjusting wiper speed in AUTO mode. Summary of the Invention

[0006] The purpose of this invention is to provide a wiper system control method and a wiper system control device, thereby solving at least one of the aforementioned technical problems.

[0007] This invention provides the following solution:

[0008] According to one aspect of the present invention, a wiper system control method is provided, the wiper system control method comprising:

[0009] An acceleration trigger zone and a deceleration trigger zone are set between the automatic mode and the adjacent modes above and below the wiper system;

[0010] Based on the current automatic mode of the wiper system, the wiper speed can be increased or decreased by triggering the acceleration or deceleration trigger zones.

[0011] Furthermore, the step of controlling the current wiper speed to increase or decrease by triggering the acceleration trigger zone or deceleration trigger zone based on the current automatic mode lockout of the wiper system includes:

[0012] The gear locking operation method includes turning the gear knob out of one gear and into another gear to lock the current gear;

[0013] The operation of gear triggering includes turning the gear knob out of the locked automatic gear position and into the acceleration trigger zone or deceleration trigger zone to control the current wiper speed.

[0014] Furthermore, the automatic mode lock of the wiper system includes:

[0015] When the gear selector knob is rotated out from the adjacent gear selector and into the automatic gear selector, the wiper system is locked in the automatic gear selector state.

[0016] When the gear selector knob is rotated out of the automatic gear position and into the adjacent gear position, the wiper system is deactivated from the automatic gear state.

[0017] Furthermore, the acceleration trigger zone or deceleration trigger zone includes:

[0018] Before the wiper system is locked in automatic mode, the function of controlling the current wiper speed by entering or exiting the acceleration or deceleration trigger zone via the gear knob is ineffective.

[0019] After the wiper system is locked in automatic mode, the function of controlling the current wiper speed by entering or exiting the acceleration trigger zone or deceleration trigger zone through the gear knob is activated.

[0020] The function to control the current wiper speed is activated when the gear knob is turned into the acceleration or deceleration trigger zone to control the current wiper speed.

[0021] Furthermore, controlling the current wiper speed includes:

[0022] The current wiper speed is controlled to increase or decrease based on the length of time the gear knob remains in the acceleration or deceleration trigger zone.

[0023] If the time the gear selector knob remains in the acceleration or deceleration trigger zone increases, the current wiper speed will increase or decrease.

[0024] Furthermore, controlling the current wiper speed also includes:

[0025] The preset wiper speed setting corresponds to the number of times the corresponding speed knob is turned in and out of the acceleration or deceleration trigger zone.

[0026] If the number of times the wiper is screwed into and out of the acceleration trigger zone increases, the current wiper speed setting will increase.

[0027] If the number of times the deceleration trigger zone is screwed in and out increases, the current wiper speed setting will decrease.

[0028] Furthermore, controlling the current wiper speed also includes:

[0029] The wiper system determines whether the gear selector knob has been turned into automatic mode for more than a preset time threshold.

[0030] If the gear selector knob is turned into automatic mode for more than a preset time threshold, the wiper system locks into automatic mode and detects the acceleration trigger zone and deceleration trigger zone.

[0031] If the gear selector knob is detected moving from the automatic gear position into or out of the acceleration trigger zone or deceleration trigger zone, the wiper system controls the reciprocating rotation frequency of the wiper motor and controls the vehicle display system.

[0032] Based on the number of times or the duration of the gear knob moving from the automatic gear position to and from the acceleration trigger zone or the deceleration trigger zone, the wiper system controls the wiper motor to adjust the reciprocating rotation frequency.

[0033] The wiper system controls the reciprocating rotation frequency of the wiper motor, and the vehicle display system displays the corresponding wiper speed gear information.

[0034] The wiper motor reciprocates, driving the wiper to move.

[0035] Furthermore, the provision of acceleration trigger zones and deceleration trigger zones between the automatic mode and adjacent upper and lower modes of the wiper system includes:

[0036] The acceleration trigger zone and the deceleration trigger zone extend from the edge of the automatic gear position to the adjacent gear position, and a blank area is reserved between them;

[0037] Based on the current automatic mode lock status of the wiper system, when the gear knob is rotated out of the acceleration trigger zone or deceleration trigger zone and into the reserved blank area, the wipers maintain the current speed or stop moving.

[0038] Furthermore, the gear selector knob includes:

[0039] The gear selector knob resets from the acceleration trigger area or the deceleration trigger area back to the automatic gear position;

[0040] The windshield wipers maintain their current speed when the gear selector knob automatically resets to the automatic mode.

[0041] According to one aspect of the present invention, a wiper system control device is provided, the wiper system control device comprising:

[0042] The gear acquisition module is used to set acceleration trigger zones and deceleration trigger zones between the automatic gear and the adjacent gears above and below in the wiper system.

[0043] The speed control module is used to control the current wiper speed to increase or decrease based on the current automatic mode status of the wiper system by triggering the acceleration or deceleration trigger zone.

[0044] Compared with the prior art, the present invention has the following advantages:

[0045] This application unifies the operation terminal of the wiper system by setting acceleration trigger zones and deceleration trigger zones between automatic transmission and adjacent gears, allowing the driver to complete the wiper control operation with a single operation action on the same terminal.

[0046] This application distinguishes between the locked and unlocked states of automatic transmission and establishes the activation conditions for acceleration and deceleration trigger zones. This avoids the problem of interference between hierarchical functions caused by using a single operation action on a unified operating terminal, so that the acceleration and deceleration trigger zones only cooperate to serve the wiper speed adjustment in the automatic transmission locked state.

[0047] This application sets acceleration and deceleration trigger zones at adjacent positions on the upper and lower sides of the automatic transmission. This not only does not weaken the reliability and accuracy of the original "4-speed" blind operation scheme, but also further improves the efficiency of "blind operation".

[0048] This application combines the original "4 gears" and the acceleration and deceleration trigger zones onto the same operating terminal, allowing the wiring harness to be guided to the same operating terminal, simplifying the assembly process, reducing material consumption, and helping to reduce the types of maintenance parts.

[0055] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0056] Figure 1 This is a flowchart of a wiper system control method provided by one or more embodiments of the present invention.

[0057] like Figure 1 The wiper system control methods shown include:

[0058] Step S1: Set an acceleration trigger zone and a deceleration trigger zone between the automatic mode and the adjacent modes above and below the wiper system, respectively;

[0059] Step S2: Based on the current automatic mode lockout of the wiper system, control the current wiper speed to increase or decrease by triggering the acceleration trigger zone or deceleration trigger zone.

[0060] Compared with the prior art, the present invention has the following advantages:

[0061] This application unifies the operation terminal of the wiper system by setting acceleration trigger zones and deceleration trigger zones between automatic transmission and adjacent gears, allowing the driver to complete the wiper control operation with a single operation action on the same terminal.

[0062] This application distinguishes between the locked and unlocked states of automatic transmission and establishes the activation conditions for acceleration and deceleration trigger zones. This avoids the problem of interference between hierarchical functions caused by using a single operation action on a unified operating terminal, so that the acceleration and deceleration trigger zones only cooperate to serve the wiper speed adjustment in the automatic transmission locked state.

[0063] This application sets acceleration and deceleration trigger zones at adjacent positions on the upper and lower sides of the automatic transmission. This not only does not weaken the reliability and accuracy of the original "4-speed" blind operation scheme, but also further improves the efficiency of "blind operation".

[0064] This application combines the original "4 gears" and the acceleration and deceleration trigger zones onto the same operating terminal, allowing the wiring harness to be guided to the same operating terminal, simplifying the assembly process, reducing material consumption, and helping to reduce the types of maintenance parts.

[0065] Specifically, the common vehicle wiper control terminal is a multi-position rotary switch (from bottom to top) with "OFF", "AUTO", "LO", and "HI" positions. Some models may also have a "MIST" position below the "OFF" position. Some models may choose other types of switches, but they basically maintain a four-position switch combination.

[0066] Choosing "4 gears" has the advantage of "blind operation". For example, choosing the first and last gears does not require complicated thinking. You can simply turn or switch the gear switch to the extreme end. Then, the second and third gears can be selected by turning it back one gear from the extreme end. Therefore, it will not put a burden on muscle memory or mental attention.

[0067] For example, some vehicles have a "MIST" gear, but it is designed as a non-steady-state switch so that it can easily return to the "OFF" gear, maintaining the "four gears" and "blind operation" advantage of "OFF", "AUTO" (automatic), "LO", and "HI". Only the "OFF", "AUTO" (automatic), "LO", and "HI" gears are generally designed as steady-state switches.

[0068] Therefore, in order not to destroy the original "4-speed" and "blind operation" advantages of existing vehicles, they usually set up a separate operating terminal position and set up "1", "2", "3" and "4" speed gears specifically to cooperate with "AUTO mode", so as to make up for the speed fine adjustment under "AUTO mode".

[0069] However, this also increases the number of operating terminals, leading to increased manufacturing complexity and a more complicated operating process. Drivers need to move from one operating terminal to another to make fine-tuning adjustments to speed in "AUTO" mode, which is detrimental to training muscle memory and mental focus.

[0070] The system even uses the vehicle's infotainment system to generate a UI interface to compensate for the minor speed adjustments in "AUTO" mode. While this can compensate for the limited number of gears, generating a UI interface to compensate for these minor speed adjustments in "AUTO" mode consumes a significant amount of visual resources and is detrimental to driving safety.

[0071] In this embodiment, by setting acceleration trigger zones and deceleration trigger zones (corresponding to the "+" and "-" of the actual vehicle's windshield wiper speed control, or "sensitivity adjustment +" and "sensitivity adjustment -") between the automatic mode and the adjacent modes of the wiper system, the number of vehicle wiper operation terminals is kept within a certain range.

[0072] Only when the current wiper system is locked in automatic mode can the current wiper speed be increased or decreased by triggering the acceleration or deceleration trigger zone, so that the speed fine adjustment corresponds to the "AUTO" mode.

[0073] Since the current wiper system only controls the wiper speed by triggering the acceleration or deceleration trigger zones when it is locked in automatic mode, the triggering of the acceleration or deceleration trigger zones will not affect the functions of other modes.

[0074] The driver can first turn the rotary switch into automatic mode to lock the wiper system in automatic mode, and then fine-tune the rotary switch to control the wiper speed to increase or decrease. Therefore, this application unifies the control method of the existing two vehicle wiper operation terminals into one vehicle wiper operation terminal without destroying the original "4-speed" and "blind operation" advantages.

[0075] In this embodiment, controlling the current wiper speed to increase or decrease by triggering the acceleration trigger zone or deceleration trigger zone, based on the current automatic mode lockout of the wiper system, includes:

[0076] The gear locking operation method includes turning the gear knob out of one gear and into another gear to lock the current gear;

[0077] The operation of gear triggering includes turning the gear knob out of the locked automatic gear position and into the acceleration trigger zone or deceleration trigger zone to control the current wiper speed.

[0078] Specifically, the rotary gear selector knob is not the only switch style; you can also choose a toggle switch or other styles.

[0079] Each gear lock means that the gear function is activated. Since it is necessary to obtain the operation of the "AUTO" gear and "+" and "-" (corresponding to the acceleration trigger zone or deceleration trigger zone) from the operation terminal of the same gear knob, the gear at the "AUTO" level needs to be "locked" before the operation of the "+" and "-" levels can be responded to.

[0080] For example, when the current wiper system is locked at low wiper speed in the "LO" position, the initial voltage level combination of "LO" and "AUTO" is "1, 0". When the voltage level combination of "LO" and "AUTO" is "0, 1", the corresponding speed control knob moves from "LO" to "AUTO", and the current wiper system is locked in "AUTO" based on the voltage level combination of "0, 1". Other voltage level combinations such as "0, 0" and "1, 1" are not used as valid speed control lock or unlock states in the wiper system.

[0081] For example, when the "AUTO" gear is locked, if the gear knob is moved from the "AUTO" gear to the "+" position, the voltage levels of the "LO" gear and the "AUTO" gear are "0" and "0", respectively. This does not disrupt the locked steady state of the "AUTO" gear, thus enabling the gear knob to be rotated out of the locked automatic gear and into the acceleration trigger zone, thereby triggering the acceleration trigger zone.

[0082] Similarly, the principle for triggering the deceleration trigger zone is the same as that for triggering the acceleration trigger zone.

[0083] Level signals can be stored and recognized using the vehicle's operating system, or they can be implemented by designing digital gate circuits.

[0084] In this embodiment, locking the wiper system in automatic mode includes:

[0085] When the gear selector knob is turned out from the adjacent gear position and turned into the automatic gear position, the wiper system is locked in the automatic mode.

[0086] When the gear selector knob is turned out of the automatic position and into the adjacent position, the wiper system will deactivate from the automatic mode.

[0087] Specifically, as the knob is turned in and out, the gear shift is only completed when one gear is disengaged and another is engaged, thus avoiding so-called "neutral" or "ambiguous gear".

[0088] In this embodiment, the acceleration trigger zone or deceleration trigger zone includes:

[0089] Before the wiper system is locked in automatic mode, the function of controlling the current wiper speed by moving the gear knob into or out of the acceleration or deceleration trigger zone will not be effective.

[0090] After the wiper system is locked in automatic mode, the current wiper speed can be controlled by moving the speed knob into or out of the acceleration or deceleration trigger zone.

[0091] The function of controlling the current wiper speed is activated by turning the gear knob into the acceleration or deceleration trigger zone to control the current wiper speed.

[0092] Specifically, based on the design of "OFF", "AUTO" (automatic), "LO", and "HI" as steady-state switches, trigger zones or trigger positions can be set on the upper and lower sides of "AUTO". Each time the "AUTO" is turned into "+" or "-", the vehicle's system records the reversal of the "+" or "-" signal, thereby generating a command to adjust the wiper speed.

[0093] Besides being locked in "AUTO" mode, operations with "+" or "-" may sometimes bypass "AUTO" mode, such as going directly from "LO" mode to "OFF" mode, or vice versa. Since "OFF" mode, "LO" mode, and "HI" mode are all fixed values, their values ​​will not be changed by "+" or "-".

[0094] Typically, determining the voltage level of a switch requires a "debouncing" process, which involves lengthening the dwell time at a certain position to identify a stable voltage level. By controlling the delay, a time gap can be reserved for the locked position, thus preventing the "+" or "-" signals from taking effect when the switch transitions from "LO" to "OFF" or vice versa, and avoiding the activation of "+" or "-" signals when crossing the "AUTO" position.

[0095] In this embodiment, controlling the current wiper speed includes:

[0096] The speed of the wipers is controlled to increase or decrease depending on the length of time the gear knob is turned into the acceleration or deceleration trigger zone.

[0097] If the speed control knob remains in the acceleration or deceleration trigger zone for an extended period, the current wiper speed will increase or decrease accordingly.

[0098] Specifically, existing technologies commonly use "1", "2", "3", and "4" settings to fine-tune the wiper speed in "AUTO mode", but this is somewhat crude. Alternatively, the vehicle's computer can record more speed settings, but this takes up the driver's visual resources.

[0099] The "+" or "-" buttons in this application allow for more speed settings without consuming the driver's visual resources, while maintaining a straight view of the road. The vehicle's computer can determine the duration the driver turns the knob into the "+" or "-" position to gradually accelerate or decelerate the wipers. The driver can directly observe the changes in the wiper speed to get feedback on their actions, and stop operating the wipers when the appropriate speed is reached.

[0100] The "+" or "-" position can be a continuous resistance or capacitive trigger zone, or a switching contact. It can be a trigger signal that changes continuously (with a range), or a trigger signal "point" (level inversion).

[0101] In this embodiment, controlling the current wiper speed further includes:

[0102] Preset wiper speed settings, and the number of times the corresponding speed knob is turned in and out of the acceleration or deceleration trigger zone;

[0103] If the number of times the wiper is turned in and out of the acceleration trigger zone increases, the current wiper speed setting will increase.

[0104] If the number of times the deceleration trigger zone is rotated in and out increases, the current wiper speed setting will decrease.

[0105] Specifically, in this embodiment, in order to avoid accidentally triggering "+" or "-" when passing through the "AUTO" position and causing a change in wiper speed, one cycle of entering and exiting the acceleration trigger zone or deceleration trigger zone can be regarded as one operation cycle for adjusting the wiper speed.

[0106] If the operation skips from "AUTO," it will only involve entering "+" or "-" from "AUTO," without the process of returning to "AUTO" from "-" or "+," or only the process of returning to "AUTO" from "+" or "-," without the process of entering "-" or "+" from "AUTO." This avoids ambiguity in the wiper speed adjustment commands when a complete operation cycle is not completed.

[0107] In this embodiment, controlling the current wiper speed further includes:

[0108] The wiper system determines whether the gear selector knob has been turned into automatic mode for more than a preset time threshold.

[0109] If the gear selector knob is turned into automatic mode for more than a preset time threshold, the wiper system will lock into automatic mode and detect the acceleration and deceleration trigger zones.

[0110] If the gear selector knob is detected moving from the automatic gear position into or out of the acceleration or deceleration trigger zone, the wiper system controls the reciprocating frequency of the wiper motor and controls the vehicle's display system.

[0111] Based on the number of times or the duration of the gear selector knob moving from the automatic gear position to the acceleration trigger zone or the deceleration trigger zone, the wiper system controls the wiper motor to adjust the reciprocating rotation frequency.

[0112] The vehicle's infotainment system displays the corresponding wiper speed setting based on the frequency of the wiper motor's reciprocating rotation, controlled by the wiper system.

[0113] The wiper motor rotates back and forth, driving the wiper to move.

[0114] Specifically, by rotating the gear selector knob from the automatic gear position to the acceleration or deceleration trigger zone, a trigger signal is generated, which controls the linkage between the vehicle's infotainment system and the motor, displays the gear position information, and controls the motor's movement according to the corresponding information.

[0115] Taking advantage of the vehicle's computer storing a large amount of gear information, the wiper motor can be precisely controlled.

[0116] In this embodiment, the acceleration trigger zone and deceleration trigger zone are respectively set between the automatic mode and the adjacent upper and lower modes of the wiper system, including:

[0117] The acceleration trigger zone and deceleration trigger zone extend from the edge of the automatic gear position to the adjacent gear position, and a blank area is reserved between them;

[0118] Depending on the current automatic mode of the wiper system, if the gear selector knob is turned out of the acceleration or deceleration trigger zone and into the reserved blank area, the wipers will maintain the current speed or stop moving.

[0119] Specifically, the acceleration trigger zone and deceleration trigger zone are designed for automatic transmissions. They extend from the edge of the automatic transmission to the adjacent gears, and the reserved blank area between them is more in line with operating habits.

[0120] The acceleration and deceleration trigger zones form a blank area with the non-automatic gear, which can mark the boundaries of the operation.

[0121] When the gear selector knob is turned out of the acceleration or deceleration trigger zone and into the reserved blank area, it means that the operation is too excessive. The driver can be prompted to keep the current speed or pause the operation by maintaining the current speed of the windshield wipers, so that the driver can return to the normal trigger position.

[0122] In this embodiment, the gear selector knob includes:

[0123] The gear selector knob automatically resets from the acceleration or deceleration trigger zone back to the automatic gear position.

[0124] The windshield wipers will automatically return to automatic mode by rotating the gear selector knob, and the wipers will maintain the current speed.

[0125] Specifically, the "OFF," "AUTO," "LO," and "HI" gear selectors are typically designed as steady-state switches with a "snap-in" mechanism, facilitating blind operation. While acceleration or deceleration trigger zones are added, their activation depends on the driver's current speed adjustment needs. If the driver were to manually return the knob to "AUTO" after the speed adjustment, it would hinder blind operation and pose a safety hazard. Therefore, the gear selector knob needs to automatically reset from the acceleration or deceleration trigger zones back to the automatic gear position.

[0126] Figure 2 This is a structural diagram of a wiper system control device provided in one or more embodiments of the present invention.

[0127] like Figure 2 The wiper system control device shown includes: a gear selection module and a speed control module;

[0128] The gear acquisition module is used to set acceleration trigger zones and deceleration trigger zones between the automatic gear and the adjacent gears above and below in the wiper system.

[0129] The speed control module is used to control the current wiper speed to increase or decrease based on the current automatic mode status of the wiper system by triggering the acceleration or deceleration trigger zone.

[0130] It is worth noting that although this system only discloses the gear acquisition module and the speed control module, it does not mean that this device is limited to the above-mentioned basic functional modules. On the contrary, what this invention is meant to express is that, based on the above-mentioned basic functional modules, those skilled in the art can add one or more functional modules in combination with the prior art to form an infinite number of embodiments or technical solutions. That is to say, this system is open rather than closed. It cannot be assumed that the scope of protection of the claims of this invention is limited to the above-disclosed basic functional modules just because this embodiment only discloses a few basic functional modules.

[0131] Figure 3 This is a schematic diagram of the operation gear position according to a specific embodiment of the present invention.

[0132] like Figure 3 As shown in this specific embodiment, a sensitivity adjustment "+" and a sensitivity adjustment "-" are set between the "AUTO" setting and the adjacent "OFF" and "LO" settings.

[0133] The sensitivity adjustment "+" and sensitivity adjustment "-" are used to adjust the wiper speed in "AUTO" mode. The "+" and "-" buttons are located on the side closest to the "AUTO" setting, with a gap between them and the "OFF" and "LO" settings. Turning the knob out of the "AUTO" setting will first engage either the sensitivity adjustment "+" or the sensitivity adjustment "-".

[0134] The "AUTO" setting is self-locking, and both the "+" and "-" sensitivity adjustments are self-resetting. When you release the knob while adjusting the sensitivity to "+" or "-", it will automatically return to the "AUTO" setting.

[0135] Figure 4 This is a flowchart of the automatic wiper function according to a specific embodiment of the present invention.

[0136] like Figure 4 As shown, in this specific embodiment, the wiper control system first determines whether it is locked in the automatic wiper (AUTO) mode, and then sends a sensitivity adjustment signal to the wiper control system. The wiper control system sends the sensitivity signal to the central control unit and the wiper motor. The central control unit is used to display it on the instrument panel or HOD, and the wiper motor operates according to the set sensitivity level.

Claims

1. A windshield wiper system control method, characterized in that, The wiper system control method includes: An acceleration trigger zone and a deceleration trigger zone are set between the automatic mode and the adjacent modes above and below the wiper system; The wiper system determines whether the gear selector knob has been turned into automatic mode for more than a preset time threshold. If the gear selector knob is turned into automatic mode for more than a preset time threshold, the wiper system locks into automatic mode and detects the acceleration trigger zone and deceleration trigger zone. If the gear selector knob is detected moving from the automatic gear position into or out of the acceleration trigger zone or deceleration trigger zone, the wiper system controls the reciprocating rotation frequency of the wiper motor and controls the vehicle display system. Based on the current automatic mode lock status of the wiper system, the current wiper speed can be increased or decreased by triggering the acceleration or deceleration trigger zones. The acceleration or deceleration trigger zones include: The gear locking operation method includes turning the gear knob out of one gear and into another gear to lock the current gear; The operation of gear triggering includes turning the gear knob out of the locked automatic gear position and into the acceleration trigger zone or deceleration trigger zone to control the current wiper speed. The gear selector knob resets from the acceleration trigger zone or deceleration trigger zone back to the automatic gear position, and the wipers maintain the current speed unchanged. Before the wiper system is locked in automatic mode, the function of controlling the current wiper speed by moving the gear knob into or out of the acceleration or deceleration trigger zone will not be effective. After the wiper system is locked in automatic mode, the current wiper speed is controlled by moving the gear knob into or out of the acceleration or deceleration trigger zone. The windshield wiper system has acceleration and deceleration trigger zones between the automatic mode and adjacent speeds, including: The acceleration trigger zone and the deceleration trigger zone extend from the edge of the automatic gear position to the adjacent gear position, and a blank area is reserved between them; Depending on the current automatic mode of the wiper system, turning the gear knob out of the acceleration or deceleration trigger zone and into the reserved blank area will cause the wipers to maintain the current speed or stop moving.

2. The wiper system control method according to claim 1, characterized in that, The automatic mode lockout state of the wiper system includes: When the gear selector knob is rotated out from the adjacent gear selector and into the automatic gear selector, the wiper system is locked in the automatic gear selector state. When the gear selector knob is rotated out of the automatic gear position and into the adjacent gear position, the wiper system is deactivated from the automatic gear state.

3. The wiper system control method according to claim 2, characterized in that, The control of the current wiper speed includes: The current wiper speed is controlled to increase or decrease based on the length of time the gear knob remains in the acceleration or deceleration trigger zone. If the time the gear selector knob remains in the acceleration or deceleration trigger zone increases, the current wiper speed will increase or decrease.

4. The wiper system control method according to claim 3, characterized in that, The control of the current wiper speed also includes: The preset wiper speed setting corresponds to the number of times the corresponding speed knob is turned in and out of the acceleration or deceleration trigger zone. If the number of times the wiper is screwed into and out of the acceleration trigger zone increases, the current wiper speed setting will increase. If the number of times the deceleration trigger zone is screwed in and out increases, the current wiper speed setting will decrease.

5. The wiper system control method according to claim 4, characterized in that, The control of the current wiper speed also includes: Based on the number of times or the duration of the gear knob moving from the automatic gear position to and from the acceleration trigger zone or the deceleration trigger zone, the wiper system controls the wiper motor to adjust the reciprocating rotation frequency. The wiper system controls the reciprocating rotation frequency of the wiper motor, and the vehicle display system displays the corresponding wiper speed gear information. The wiper motor reciprocates, driving the wiper to move.

6. A wiper system control device for implementing the wiper system control method as described in any one of claims 1 to 5, characterized in that, The wiper system control device includes: The gear acquisition module is used to set acceleration trigger zones and deceleration trigger zones between the automatic gear and the adjacent gears above and below in the wiper system. The speed control module is used to control the current wiper speed to increase or decrease based on the current automatic mode status of the wiper system by triggering the acceleration or deceleration trigger zone.
