[0030] The development of automotive wiper systems has gradually evolved from the original manual wipers to more advanced automatic wiper systems, which aim to improve the comfort and safety of the driver. However, existing automatic wiper systems have some limitations, such as: in rainy and snowy weather, they cannot provide the best wiping effect, or they are frequently triggered when not needed, causing wiper blade wear and noise problems.

[0031] According to an embodiment of the present application, an embodiment of a control method for vehicle wipers is provided. It should be noted that the steps shown in the flowchart of the accompanying drawings can be executed in a computer system such as a set of computer executable instructions, and although a logical order is shown in the flowchart, in some cases, the steps shown or described herein can be executed in a different order than that shown here.

[0032] Figure 1 is a method according to an embodiment of the present application, as shown in Figure 1 the method comprises the following steps:

[0033] Step S102, obtaining the wiper sensitivity model of the target user and the current rainfall information.

[0034] In step S102, the wiper sensitivity models of multiple target users can be collected in order to provide different wiper sensitivity information for different target users. The wiper sensitivity model can be directly input, or it can be selected by the target user himself, and the wiper sensitivity model can automatically adjust the wiping speed and wiping frequency in the wiper sensitivity model by learning the preference settings of the target user under different weather conditions, in order to provide the most suitable wiping effect. The wiper sensitivity model at least includes the preferred wiper speed information of the target user, wherein the preferred wiper speed information is the preferred wiper speed of the target user under different rainfall, and in one embodiment of the present application, the preferred wiper speed information also includes the preferred wiper speed of the target user under different snowfall, in order to adapt to the wiper wiping operation under different rainy and snowy weather.

[0035] In step S102, the current rainfall information can be obtained by a rainfall sensor, an image acquisition device, etc. The sensor uses the principle of infrared light reflection to monitor and determine the rainfall size by monitoring the change in received light. In other embodiments of the present application, time information and temperature sensor information can also be obtained to determine the current season (spring, summer, autumn, winter) and weather (rainy, snowy, sleet, etc.), and different wiper speeds can be provided for different seasons, weather, and rainfall to improve the reliability of the method.

[0036] Step S104, determining the target wiper speed based on the current rainfall information and the wiper sensitivity model.

[0037] In step S104, the current rainfall information is the current rainfall value, and in the wiper sensitivity model, the target wiper speed is determined according to different current rainfall information, so as to achieve wiper operation with target user preferred sensitivity under various rainfall. In another embodiment of the present application, the final target wiper speed can also be determined by referring to the rain and snow weather and the current vehicle speed information, thereby improving the practicality of the target wiper speed.

[0038] Step S106, controlling the vehicle wiper to perform wiper operation at the target wiper speed.

[0039] In step S106, since the wiper sensitivity model can be learned according to the use data of the target user, wiper operation that meets the target user's demand can be generated.

[0040] Through the above steps, the wiper sensitivity model of the target user can be established according to the wiper speed selected by the target user, and the target wiper speed is determined through the wiper sensitivity model of the target user and the current rainfall information, so that the target wiper speed is more in line with the sensitivity demand of the target user, thereby improving the use experience of the target user, solving the technical problem of poor use experience of the wiper system in the prior art, and further improving the comfort and safety during driving.

[0041] As an optional implementation, before obtaining the wiper sensitivity model of the target vehicle, the method further comprises:

[0042] Step S100, obtaining the preferred wiper speed information of the target user, the preferred wiper speed information being the wiper speed preferred by the target user under different rainfall.

[0043] In step S100, the preferred wiper speed information includes the target user's preferred wiper speed under different rainfall, and the rainfall scene can be divided into light rain environment, medium rain environment and heavy rain environment according to the rainfall threshold. Under the same rainfall, there is only one target user's preferred wiper speed, and under the same rainfall scene, it includes but is not limited to the target user's preferred wiper speed. The more the input target user's preferred wiper speed information, the closer the established wiper sensitivity model to the target user's preference, so as to improve the user's comfort and reduce user complaints.

[0044] In step S101, a wiper sensitivity model is established based on the preferred wiper speed information.

[0045] In step S101, the preferred wiper speed information is obtained by combining Figure 2 As shown in the figure, when the target user sets the preferred wiper speed under each rainfall scene, it corresponds to the selection of different sensitivity under the rainfall state. After the user selects the preferred wiper speed, the least square method algorithm is used to fit the relationship between the preferred wiper speed information and the sensitivity, and then the sensitivity of the discrete points between light rain to medium rain and medium rain to heavy rain can be calculated, realizing smooth wiper speed fitting and obtaining the wiper sensitivity model. The wiper sensitivity level is divided into 10 levels, the 10th level is the most sensitive, the 1st level is the least sensitive, the 10th level needs the smallest rainfall threshold, and the 1st level needs the largest rainfall threshold. According to the wiper sensitivity model, the target user's preferred wiper speed under different rainfall can be obtained.

[0046] Through the above steps, a wiper sensitivity model is established, which can automatically adjust the sensitivity level and wiper speed of the wiper according to the current rainfall to adapt to the user's preference under different rainfall conditions. In this way, whether it is light rain, medium rain or heavy rain, the wiper can run at the user's preferred speed, and the wiper speed is automatically adjusted to adapt to different driving conditions, so as to provide more personalized and comfortable driving experience.

[0047] Optionally, before obtaining the target user's preferred wiper speed information, it includes:

[0048] In step S010, a plurality of simulation demonstration scenes are generated, which are used to demonstrate the wiper wiping action at the simulation speed under the simulation rainfall environment, and the simulation rainfall and simulation speed of each simulation demonstration scene are set differently.

[0049] In combination with Figure 3As shown, in step S010, first, the simulation parameters need to be defined, the simulation parameters at least include simulated rainfall and simulated wiper speed, the simulated rainfall can set different rainfall levels, for example, light rain, moderate rain and heavy rain; the simulated wiper speed can set different wiper speeds, for example, low speed, medium speed and high speed. Through the simulation demonstration scene, the user can intuitively feel the wiper efficiency under different rainfall and different wiper speed, so that the subsequent wiper operation is closer to the psychological expectation of the target user, avoids the target user from appearing difference and complaint in perception when selecting the preferred wiper speed due to the inability to intuitively feel the real wiper speed, further improves the use experience of the target user, and makes the wiper operation more intelligent.

[0050] Step S020, determine the user preferred demonstration scene from the plurality of simulation demonstration scenes, and the wiper speed information in the user preferred demonstration scene is the preferred wiper speed information of the target user.

[0051] In step S020, different simulated rainfall and different simulated wiper speed are combined, and a simulation demonstration scene is generated for demonstration, and the target user can select a scene with a preferred wiper speed under different simulated rainfall from the simulation demonstration scene, wherein the simulation demonstration scene can be displayed in the form of animation on the entertainment host of the vehicle, the wiper speed information in the target user preferred demonstration scene is determined as the preferred wiper speed information of the target user, and then the wiper sensitivity of the target user under different simulated rainfall can be calculated.

[0052] Optionally, the simulation demonstration scene includes an initial demonstration scene, and determining the user preferred demonstration scene from the plurality of simulation demonstration scenes includes the following steps:

[0053] Step S011, generating an initial demonstration scene, the initial demonstration scene is used to demonstrate the wiper wiper action at an initial wiper speed under a simulated rainfall environment.

[0054] In step S011, the simulated rainfall environment includes a light rain environment, a moderate rain environment and a heavy rain environment, wherein the rainfall of the light rain environment is 10mm / day, the rainfall of the moderate rain environment is 25mm / day, and the rainfall of the heavy rain environment is 50mm / day, the initial wiper speed of the wiper in the light rain environment is 45 times / min, the initial wiper speed of the wiper in the moderate rain environment is 51 times / min, and the initial wiper speed of the wiper in the heavy rain environment is 57 times / min, and the host interface performs animation demonstration according to the rainfall,

[0055] Step S012, obtaining the wiper speed adjustment information of the target user, the wiper speed adjustment information is used to increase or decrease the wiper speed.

[0056] In step S012, the target user adjusts the wiper speed in the simulation demonstration scene according to the own preference, the wiper in the animation demonstration speeds up the wiping operation / slow down the wiping operation according to the adjustment of the target user on the wiping speed, so as to present the wiping speed of the wiper in the display scene to the user, and determine the preference sensitivity of the target user under different rainfall environments. In an embodiment of the present application, the adjustment range of the wiper speed under light rain environment is 42-48 times / min, the adjustment range of the wiper speed under medium rain environment is 48-54 times / min, and the adjustment range of the wiper speed under heavy rain environment is 54-60 times / min.

[0057] In step S013, the wiper speed in the initial demonstration scene is adjusted based on the wiper speed adjustment information, and the adjusted simulation demonstration scene is determined as the user preference demonstration scene.

[0058] In step S013, the wiper in the animation demonstration speeds up the wiping operation / slow down the wiping operation according to the adjustment of the target user on the wiping speed, so as to present the wiping speed of the wiper in the display scene to the user, and the target user can select the scene with the preferred wiper speed under different simulated rainfall from the scene, and the wiper speed information of the target user preference demonstration scene is determined as the preferred wiper speed information of the target user, and then the wiping sensitivity of the target user under different simulated rainfall can be calculated.

[0059] Optionally, the wiper sensitivity model is established based on the preferred wiper speed information, including the following steps:

[0060] In step S1011, the wiper sensitivity curve is fitted based on the preferred wiper speed information and the corresponding rainfall.

[0061] In combination Figure 2 As shown in step S1011, when the target user sets the preferred wiper speed information under different rainfall scenes, the corresponding is the selection of different sensitivity under the rainfall state, and when the user selects the preferred wiping speed, the least square method algorithm is used to fit the relationship between the preferred wiper speed information and the sensitivity, and then the sensitivity of the discrete points between light rain to medium rain and medium rain to heavy rain can be calculated, the smooth wiping speed fitting is realized, and the wiper sensitivity curve is obtained. Among them, the wiper sensitivity level is divided into 10 levels, the 10th level is the most sensitive, the 1st level is the least sensitive, the rainfall threshold required for the 10th level is the smallest, and the rainfall threshold required for the 1st level is the largest.

[0062] Optionally, the simulated rainfall environment includes a first rainfall environment, a second rainfall environment and a third rainfall environment, wherein the rainfall in the first rainfall environment is less than the rainfall in the second rainfall environment, and the rainfall in the second rainfall environment is less than the rainfall in the third rainfall environment.

[0063] In the embodiment, the first rainfall environment is a light rain environment, the second rainfall environment is a medium rain environment, and the third rainfall environment is a heavy rain environment. When the rainfall is less than or equal to 20 mm / day, the simulated rainfall environment is the first rainfall environment (light rain environment); when the rainfall is greater than 20 mm / day and less than or equal to 50 mm / day, the simulated rainfall environment is the second rainfall environment (medium rain environment); and when the rainfall is greater than or equal to 50 mm / day, the simulated rainfall environment is the third rainfall environment (heavy rain environment). By setting multiple rainfall environments, the target user's preferred wiper speed information under each rainfall environment can be obtained, so as to establish the wiper sensitivity, improve the matching degree of the target wiper speed and the target customer's preferred wiper speed, and optimize the intelligent degree of the wiper operation.
