Description

Technical Field

[0001] This invention relates to the field of automotive technology, and in particular to a windshield wiper speed adaptive control method, system, electronic device, and computer-readable medium. Background Technology

[0002] Currently, car windshield wiper speed mainly relies on rain sensors to automatically adjust the wiper speed, or drivers can manually adjust different wiper speeds. When driving in the rain, drivers need to frequently manually adjust the wiper speed to adapt to changes in rain intensity (such as a sudden change from light rain to heavy rain), which distracts driving attention and increases safety hazards.

[0003] Traditional automatic windshield wipers rely on rain sensors, but these sensors have a detection delay (such as the speed at which water accumulates on the windshield lags behind the actual change in rainfall), especially during heavy rain or high-speed driving, when windshield visibility can deteriorate rapidly. When a vehicle accelerates or overtakes, the spray from the vehicle in front can momentarily obscure the driver's vision, but current wiper systems cannot anticipate such sudden situations. Summary of the Invention

[0004] The present invention aims to solve at least one of the technical problems existing in the prior art, and proposes a windshield wiper speed adaptive control method and system.

[0005] In a first aspect, embodiments of the present invention provide a windshield wiper speed adaptive control method, comprising:

[0006] Real-time monitoring of throttle opening;

[0007] Determine whether the throttle opening has reached the threshold. If not, maintain the current wiper mode; otherwise, enter the throttle-associated wiper mode and proceed to the next step.

[0008] Calculate the rate of change of throttle;

[0009] Determine if the emergency scenario conditions are met. If so, force the high-speed wiper mode and water spray to be activated. If not, adjust the wiper speed according to the dynamic correlation function.

[0010] In some embodiments, the step of real-time monitoring of throttle opening includes:

[0011] The accelerator pedal opening sensor continuously outputs a signal, which the vehicle ECU reads in real time through analog-to-digital conversion and calculates the accelerator opening α.

[0012] In some embodiments, the step of determining whether the throttle opening has reached a threshold includes:

[0013] If α < 30%, the throttle opening has not reached the threshold, and it is determined that the driver has no intention to accelerate urgently, so the current wiper mode is maintained.

[0014] If α ≥ 30%, the throttle opening reaches the threshold, then it is determined that the throttle-associated wiper mode is entered, and the next step is performed.

[0015] In some embodiments, the step of calculating the rate of change of throttle includes:

[0016] Record the change in throttle opening Δα within a unit time Δt, and calculate the throttle change rate ΔT = Δα / Δt.

[0017] In some embodiments, the step of determining whether the conditions for an emergency scenario are met includes:

[0018] Instantaneous throttle opening α > 80%, throttle change rate ΔT > 50% / s;

[0019] If both conditions are met, it is determined to be an emergency scenario, and the high-speed wiper mode and water spray are forcibly triggered; if either condition is not met, it is determined to be a non-emergency scenario, and the wiper speed is adjusted according to the dynamic correlation function.

[0020] In some embodiments, the step of forcibly triggering the high-speed wiper mode and the washer spray includes: setting the wiper speed to the highest speed allowed by the system, and simultaneously triggering the washer system to clean the windshield.

[0021] In some embodiments, the step of adjusting the wiper speed according to a dynamic correlation function includes:

[0022] When 80% ≥ α ≥ 30%, adjust the wiper speed using the formula Wiper_Speed ​​= Base_Speed ​​× (1 + 0.5 × (α - 30) / 70).

[0023] When α > 80% and ΔT > 50% / s, since α has exceeded 80%, the linear formula reaches its upper limit, and the wiper speed is locked at Base_Speed ​​× 1.25.

[0024] In a second aspect, embodiments of the present invention provide a windshield wiper speed adaptive control system, comprising:

[0025] The detection unit is used to monitor the throttle opening in real time;

[0026] The first judgment unit is used to determine whether the throttle opening has reached the threshold. If not, the current wiper mode is maintained; otherwise, the throttle-associated wiper mode is entered and the next step is performed.

[0027] The calculation unit is used to calculate the rate of change of throttle.

[0028] The second judgment unit is used to determine whether the emergency scenario conditions are met. If so, the high-speed wiper mode and water spray are forcibly triggered; otherwise, the wiper speed is adjusted according to the dynamic correlation function.

[0029] Thirdly, the present invention also provides an electronic device, comprising:

[0030] One or more processors;

[0031] Memory, used to store one or more programs;

[0032] When the one or more programs are executed by the one or more processors, the one or more processors implement any of the methods.

[0033] Fourthly, the present invention also provides a computer-readable medium on which a computer program is stored, wherein the computer program, when executed by a processor, implements the steps in any of the methods described.

[0034] The windshield wiper speed adaptive control method provided by this invention monitors the throttle opening in real time; determines whether the throttle opening has reached a threshold; if not, maintains the current wiper mode; if not, enters the throttle-associated wiper mode and proceeds to the next step; calculates the throttle change rate; determines whether the sudden scenario conditions are met; if so, forcibly triggers the high-speed wiper mode and water spray; if not, adjusts the wiper speed according to a dynamic correlation function. This invention uses the throttle pedal opening and change rate as collaborative parameters for wiper speed control, achieving dynamic matching between wiper response and driving behavior, thus improving driving experience and safety.

The use of user data in this technical solution follows relevant national laws and regulations (e.g., the "Information Security Technology - Personal Information Security Specification").

[0044] In related technologies, traditional automatic windshield wipers rely on rain sensors, but these sensors have a detection delay (e.g., the speed at which water accumulates on the windshield lags behind the actual change in rainfall), especially during heavy rain or high-speed driving, when windshield visibility can deteriorate rapidly. Currently, car wiper speeds mainly rely on automatic adjustment by rain sensors or manual adjustment of different wiper speeds. Drivers need to frequently manually adjust the wiper speed to adapt to changes in rain intensity (e.g., from light rain to heavy rain), which distracts driving attention and increases safety hazards.

[0045] To address at least one of the technical problems existing in the aforementioned related technologies, the present invention provides a windshield wiper speed adaptive control method. Figure 1 The flowchart illustrates the steps of a windshield wiper speed adaptive control method provided in this embodiment of the invention.

[0046] like Figure 1 As shown, the windshield wiper speed adaptive control method includes the following steps:

[0047] Step S10: Monitor throttle opening in real time.

[0048] In this embodiment, the accelerator pedal opening sensor continuously outputs a signal, which the vehicle ECU reads in real time via analog-to-digital converter (ADC) and calculates as a percentage opening value α. This process operates at a high frequency (e.g., 100Hz) to ensure real-time data accuracy.

[0049] It is understood that the system reads the throttle opening value α from the engine control unit or directly from the throttle pedal position sensor via the vehicle's CAN bus at a fixed high frequency (typically 10ms to 100ms). α is a percentage value, ranging from 0% (fully released) to 100% (fully depressed). The throttle pedal position sensor (usually a Hall effect sensor or potentiometer) is the core hardware. It converts the mechanical position of the pedal into a linear electrical signal.

[0050] After receiving the raw value of α, the system performs simple software filtering (such as moving average filtering) to eliminate signal jitter and noise, ensuring the stability and reliability of the data.

[0051] Step S20: Determine whether the throttle opening has reached the threshold. If not, maintain the current wiper mode; otherwise, enter the throttle-associated wiper mode and proceed to the next step.

[0052] In this embodiment, the throttle opening α value is monitored in real time and compared with a preset threshold, such as 30%.

[0053] It is understandable that the filtered real-time throttle opening α is compared with a preset first threshold T1. According to the dynamic correlation function, this T1 is explicitly set to 30%.

[0054] If α < 30%, the system determines that the driver has no intention to accelerate urgently and maintains the current wiper mode. If the system determines that the driver has no intention to accelerate or has a very weak intention, the wipers do not need to be coordinated with the accelerator. In this case, the system completely hands over control to the rain sensor. The wipers operate according to the Base_Speed ​​calculated by the rain sensor based on the current rainfall intensity.

[0055] Understandably, the system does not intervene in the wiper speed control. The wiper speed is entirely set and dynamically adjusted by the rain sensor based on the detected rainfall intensity (Base_Speed). This ensures that the system does not cause any interference when the throttle opening is small, guaranteeing driving comfort and system efficiency.

[0056] If α ≥ 30%, the throttle opening reaches the threshold, and the system determines that it has entered the throttle-associated wiper mode and proceeds to the next step. The system determines that the driver has a clear intention to accelerate, at which point the vehicle may need a clearer view to cope with potentially increased speeds or changing traffic conditions.

[0057] Step S30: Calculate the rate of change of throttle.

[0058] In this embodiment, the change in throttle opening Δα within a unit time (e.g., Δt = 0.1s) is recorded, and ΔT = Δα / Δt is calculated, with the unit being % / s. This calculation uses a sliding window or difference method to smooth out noise and accurately capture the driver's pedal speed.

[0059] Record the throttle opening α(t) at the current time t and the throttle opening α(t-1) at the previous sampling time t-1.

[0060] Furthermore, the throttle change rate ΔT is calculated using the following formula: ΔT = |α(t) - α(t-1)| / Δt, where Δt is the time interval between two samplings. The unit of the calculated result ΔT is % / s, which intuitively represents the "rapidity" of the driver pressing or releasing the accelerator. This parameter is key to identifying "sudden scenarios," as rapidly pressing the accelerator often corresponds to the need for emergency overtaking or risk avoidance, at which point a moment of clear vision is crucial.

[0061] Step S40: Determine whether the emergency scenario conditions are met. If yes, force the high-speed wiper mode and water spray to be activated. If not, adjust the wiper speed according to the dynamic correlation function.

[0062] In this embodiment, determining whether the emergency scenario conditions are met involves checking two conditions simultaneously:

[0063] Instantaneous throttle opening α > 80% (deeply depressed).

[0064] Throttle change rate ΔT>50% / s (rapid depress).

[0065] If both conditions are met, it is determined to be an emergency scenario, and the high-speed wiper mode and water spray will be forcibly triggered.

[0066] If any condition is not met, it is determined to be a non-emergency scenario, and the wiper speed is adjusted according to the dynamic correlation function.

[0067] Furthermore, the process of forcibly triggering the high-speed wiper mode and washer spray involves the following steps: The system ignores the rain sensor signal. The control module directly sends a command to the execution module to set the wiper speed to the system's allowed Max_Speed ​​(maximum speed). Simultaneously, the washer system is triggered to clean the windshield. This mode lasts for a fixed period (e.g., 10 seconds), after which system control is returned to the rain sensor or basic logic.

[0068] Understandably, this step is the system's highest priority response, designed to provide the clearest view instantly.

[0069] In this embodiment, the dynamic association function is as follows:

[0070]

[0071] Furthermore, in the step of adjusting the wiper speed based on the dynamic correlation function, there are two specific cases depending on the value of α:

[0072] Case 1 (80%≥α≥30%): Perform linear boosting.

[0073] Use the formula: Wiper_Speed ​​= Base_Speed ​​× (1 + 0.5 × (α - 30) / 70)

[0074] This function, based on Base_Speed, provides an additional speed boost of up to 25% depending on the position of α within the 30% to 80% range, achieving a smooth transition.

[0075] Scenario 2 (α>80%, ΔT>50% / s): Linear range saturation. Since α has exceeded 80%, the linear formula has reached its upper limit. At this point, the wiper speed is locked at Base_Speed×1.25.

[0076] Understandably, this step establishes a direct and smooth correlation between throttle opening and wiper speed in non-emergency situations.

[0077] It is understandable that this embodiment has evolved from a simple "linear boost" to piecewise function control, including a "base range," a "linear boost range," and a "saturation range," resulting in more precise and reasonable control. The triggering condition for sudden scenarios has been improved from a single condition to a composite condition of α>80% and ΔT>50% / s, greatly reducing the possibility of false triggering. The strongest cleaning mode will only be activated under deep and rapid throttle operation. The calculation formula within the linear range ensures a smooth transition of wiper speed with changes in throttle opening, avoiding abrupt speed jumps and improving user experience and system stability.

[0078] The windshield wiper speed adaptive control method provided by this invention monitors the throttle opening in real time; determines whether the throttle opening has reached a threshold; if not, maintains the current wiper mode; if not, enters the throttle-associated wiper mode and proceeds to the next step; calculates the throttle change rate; determines whether the sudden scenario conditions are met; if so, forcibly triggers the high-speed wiper mode and water spray; if not, adjusts the wiper speed according to a dynamic correlation function. This invention uses the throttle pedal opening and change rate as collaborative parameters for wiper speed control, achieving dynamic matching between wiper response and driving behavior, thus improving driving experience and safety.

[0079] Please see Figure 2 The present invention also provides a windshield wiper speed adaptive control system. Applied to the windshield wiper speed adaptive control method provided in the above embodiments, it specifically includes:

[0080] The detection unit is used to monitor the throttle opening in real time.

[0081] In this embodiment, the accelerator pedal opening sensor continuously outputs a signal, which the vehicle ECU reads in real time via analog-to-digital converter (ADC) and calculates as a percentage opening value α.

[0084] The first judgment unit is used to determine whether the throttle opening has reached the threshold. If not, the current wiper mode is maintained; otherwise, the throttle-associated wiper mode is entered and the next step is performed.

[0085] In this embodiment, the throttle opening α value is monitored in real time and compared with a preset threshold, such as 30%.

[0086] It is understandable that the filtered real-time throttle opening α is compared with a preset first threshold T1. According to the dynamic correlation function, this T1 is explicitly set to 30%.

[0087] If α < 30%, the system determines that the driver has no intention to accelerate urgently and maintains the current wiper mode. If the system determines that the driver has no intention to accelerate or has a very weak intention, the wipers do not need to be coordinated with the accelerator. In this case, the system completely hands over control to the rain sensor. The wipers operate according to the Base_Speed ​​calculated by the rain sensor based on the current rainfall intensity.

The system determines that the driver has a clear intention to accelerate, at which point the vehicle may need a clearer view to cope with potentially increased speeds or changing traffic conditions.

[0090] The calculation unit is used to calculate the rate of change of throttle.

[0091] In this embodiment, the change in throttle opening Δα within a unit time (e.g., Δt = 0.1s) is recorded, and ΔT = Δα / Δt is calculated, with the unit being % / s. This calculation uses a sliding window or difference method to smooth out noise and accurately capture the driver's pedal speed.

[0092] Record the throttle opening α(t) at the current time t and the throttle opening α(t-1) at the previous sampling time t-1.

[0093] Furthermore, the throttle change rate ΔT is calculated using the following formula: ΔT = |α(t) - α(t-1)| / Δt, where Δt is the time interval between two samplings.

This parameter is key to identifying "sudden scenarios," as rapidly pressing the accelerator often corresponds to the need for emergency overtaking or risk avoidance, at which point a moment of clear vision is crucial.

[0094] The second judgment unit is used to determine whether the emergency scenario conditions are met. If so, the high-speed wiper mode and water spray are forcibly triggered; otherwise, the wiper speed is adjusted according to the dynamic correlation function.

[0095] In this embodiment, determining whether the emergency scenario conditions are met involves checking two conditions simultaneously:

[0096] Instantaneous throttle opening α > 80% (deeply depressed).

[0097] Throttle change rate ΔT>50% / s (rapid depress).

[0098] If both conditions are met, it is determined to be an emergency scenario, and the high-speed wiper mode and water spray will be forcibly triggered.

[0099] If any condition is not met, it is determined to be a non-emergency scenario, and the wiper speed is adjusted according to the dynamic correlation function.

[0100] Furthermore, the process of forcibly triggering the high-speed wiper mode and washer spray involves the following steps: The system ignores the rain sensor signal. The control module directly sends a command to the execution module to set the wiper speed to the system's allowed Max_Speed ​​(maximum speed). Simultaneously, the washer system is triggered to clean the windshield. This mode lasts for a fixed period (e.g., 10 seconds), after which system control is returned to the rain sensor or basic logic.

[0101] Understandably, this step is the system's highest priority response, designed to provide the clearest view instantly.

[0103]

[0104] Furthermore, in the step of adjusting the wiper speed based on the dynamic correlation function, there are two specific cases depending on the value of α:

[0105] Case 1 (80%≥α≥30%): Perform linear boosting.

[0106] Use the formula: Wiper_Speed ​​= Base_Speed ​​× (1 + 0.5 × (α - 30) / 70)

Claims

1. A windshield wiper speed adaptive control method, characterized in that, It includes: Real-time monitoring of throttle opening; Determine whether the throttle opening has reached the threshold. If not, maintain the current wiper mode; otherwise, enter the throttle-associated wiper mode and proceed to the next step. Calculate the rate of change of throttle; Determine if the emergency scenario conditions are met. If so, force the high-speed wiper mode and water spray to be activated. If not, adjust the wiper speed according to the dynamic correlation function.

2. The windshield wiper speed adaptive control method according to claim 1, characterized in that, The steps for real-time monitoring of throttle opening include: The accelerator pedal opening sensor continuously outputs a signal, which the vehicle ECU reads in real time through analog-to-digital conversion and calculates the accelerator opening α.

3. The windshield wiper speed adaptive control method according to claim 2, characterized in that, The step of determining whether the throttle opening has reached a threshold includes: If α < 30%, the throttle opening has not reached the threshold, and it is determined that the driver has no intention to accelerate urgently, so the current wiper mode is maintained. If α ≥ 30%, the throttle opening reaches the threshold, then it is determined that the throttle-associated wiper mode is entered, and the next step is performed.

4. The windshield wiper speed adaptive control method according to claim 3, characterized in that, The steps for calculating the rate of change of throttle include: Record the change in throttle opening Δα within a unit time Δt, and calculate the throttle change rate ΔT = Δα / Δt.

5. The windshield wiper speed adaptive control method according to claim 4, characterized in that, The steps for determining whether the conditions for an emergency scenario are met include: Instantaneous throttle opening α > 80%, throttle change rate ΔT > 50% / s; If both conditions are met, it is determined to be an emergency scenario, and the high-speed wiper mode and water spray are forcibly triggered; if either condition is not met, it is determined to be a non-emergency scenario, and the wiper speed is adjusted according to the dynamic correlation function.

6. The windshield wiper speed adaptive control method according to claim 5, characterized in that, The steps of forcibly triggering the high-speed wiper mode and the washer spray include: setting the wiper speed to the highest speed allowed by the system, and simultaneously triggering the washer system to clean the windshield.

7. The windshield wiper speed adaptive control method according to claim 5, characterized in that, The steps for adjusting wiper speed based on a dynamic correlation function include: When 80% ≥ α ≥ 30%, adjust the wiper speed using the formula Wiper_Speed ​​= Base_Speed ​​× (1 + 0.5 × (α - 30) / 70). When α > 80% and ΔT > 50% / s, since α has exceeded 80%, the linear formula reaches its upper limit, and the wiper speed is locked at Base_Speed ​​× 1.
