[0002] With the rapid development of society and the accelerated pace of work, cars have become an important commuting and production tool.

[0028] In order to enable those skilled in the art to better understand the scheme of the present invention, the technical scheme in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0029] It should be noted that the terms "first", "second", etc. in the specification and claims of the present invention and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchanged where appropriate, so that the embodiments of the present invention described herein can be implemented in an order other than those illustrated or described herein.

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

[0031] According to an embodiment of the present invention, an embodiment of a control method for a vehicle wiper 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 can be executed in an order different from that shown here.

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

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

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

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

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

[0037] In step S104, the current rainfall information is the current rainfall value. In the wiper sensitivity model, the target wiper speed is determined according to different current rainfall information, so as to achieve a wiper operation with a target user preference sensitivity under various rainfalls. In another embodiment of the present application, the final target wiper speed can be comprehensively determined with reference to rainy and snowy weather and current vehicle speed information, thereby improving the practicality of the target wiper speed.

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

[0039] In step S106, since the wiper sensitivity model can be learned according to the usage data of the target user, a wiper operation that meets the needs of the target user can be generated.

[0040] Through the above steps, a wiper sensitivity model of the target user can be established according to the wiper speed selected by the target user. The target wiper speed can be 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 requirements of the target user, thereby improving the user experience of the target user, solving the technical problem of poor user experience of the wiper system in the prior art, and thus improving the comfort and safety during driving.

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

[0042] Step S100, obtaining preferred wiper speed information of a target user, where the preferred wiper speed information is the preferred wiper speed of the target user under different rainfall amounts.

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

[0044] Step S101: establishing a wiper sensitivity model based on preferred wiper speed information.

[0045] In step S101, Figure 2 As shown in the figure, when the target user sets the preferred wiper speed information under each rainfall scenario, the corresponding choice is the selection of different sensitivities under the rainfall state. After the user selects the preferred wiper speed, the relationship between the preferred wiper speed information and the sensitivity is fitted using the least squares algorithm, and then the sensitivity of discrete points between light rain to moderate rain and moderate rain to heavy rain can be calculated to achieve smooth wiper speed fitting and obtain the wiper sensitivity model. Among them, the wiper sensitivity level is divided into 10 levels, 10 is the most sensitive, 1 is the least sensitive, the required rainfall threshold is the smallest at level 10, and the required rainfall threshold is the largest at level 1. 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 wiper sensitivity level and wiper speed according to the current rainfall to adapt to the user's preferences under different rainfall conditions. In this way, whether it is light rain, moderate rain or heavy rain, the wiper can run at the user's preferred speed, and automatically adjust the wiper speed to adapt to different driving conditions, so as to provide a more personalized and comfortable driving experience.

[0047] Optionally, before obtaining the preferred wiper speed information of the target user, the following steps are included:

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

[0049] Combination Figure 3As shown, in step S010, firstly, simulation parameters need to be defined. The simulation parameters include at least simulated rainfall and simulated scraping speed. The simulated rainfall can be set to different rainfall levels, such as light rain, moderate rain and heavy rain; the simulated scraping speed can be set to different scraping speeds, such as low speed, medium speed and high speed. The simulation demonstration scene allows users to intuitively feel the scraping efficiency under different rainfall and different scraping speeds, so that the subsequent scraping operation is closer to the psychological expectations of the target user, avoiding the target user's perception differences and complaints when choosing the preferred wiper speed due to the inability to intuitively feel the actual scraping speed, further improving the user experience of the target user, and making the scraping operation more intelligent.

[0050] Step S020, determining a user preferred demonstration scene from a plurality of simulated demonstration scenes, wherein the windshield wiper speed information in the user preferred demonstration scene is the preferred windshield wiper speed information of the target user.

[0051] In step S020, different simulated rainfall amounts and different simulated wiping speeds are combined, and a simulated demonstration scene is generated for demonstration, from which the target user can select scenes with preferred wiper speeds under different simulated rainfall amounts, wherein the simulated demonstration scene can be displayed in an animated manner on the vehicle's entertainment host, and the wiper speed information in the target user's preferred demonstration scene is determined as the target user's preferred wiper speed information, and then the target user's wiper sensitivity under different simulated rainfall amounts can be calculated.

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

[0053] Step S011, generating an initial demonstration scene, wherein the initial demonstration scene is used to demonstrate the wiper wiping action at an initial wiping speed in 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 in the light rain environment is 10 mm / day, the rainfall in the moderate rain environment is 25 mm / day, the rainfall in the heavy rain environment is 50 mm / day, the initial wiping speed of the wiper in the light rain environment is 45 times / min, the initial wiping speed of the wiper in the moderate rain environment is 51 times / min, and the initial wiping speed of the wiper in the light rain environment is 57 times / min. The host interface performs animation demonstration according to this rainfall.

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

[0056] In step S012, the target user adjusts the wiper speed in the simulation demonstration scene according to his / her preference, and the wiper in the animation demonstration speeds up / slows down the wiper operation according to the adjustment of the wiper speed by the target user, so as to present the wiper speed in the approximate display scene to the user and determine the target user's preference sensitivity in different rain environments. In one implementation of the present application, the wiper speed adjustment range in a light rain environment is 42-48 times / min, the wiper speed adjustment range in a moderate rain environment is 48-54 times / min, and the wiper speed adjustment range in a heavy rain environment is 54-60 times / min.

[0057] Step S013, adjusting the wiper speed in the initial demonstration scene based on the wiper speed adjustment information, and determining the adjusted simulated demonstration scene as the user preferred demonstration scene.

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

[0059] Optionally, establishing a wiper sensitivity model based on the preferred wiper speed information includes the following steps:

[0060] Step S1011, fitting a wiper sensitivity curve based on the preferred wiper speed information and the corresponding rainfall.

[0061] Combination Figure 2 As shown, in step S1011, when the target user sets the preferred wiper speed information under each rainfall scenario, the corresponding information is the selection of different sensitivities under the rainfall state. After the user selects the preferred wiper speed, the relationship between the preferred wiper speed information and the sensitivity is fitted using the least squares algorithm, and then the sensitivity of discrete points between light rain to moderate rain and moderate rain to heavy rain can be calculated, and a smooth wiper speed fitting is achieved to obtain a wiper sensitivity curve. Among them, the wiper sensitivity level is divided into 10 levels, 10 is the most sensitive, 1 is the least sensitive, 10 requires the smallest rainfall threshold, and 1 requires the largest rainfall threshold.

[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 this embodiment, the first rainfall environment is a light rain environment, the second rainfall environment is a moderate 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 (moderate 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 preferred wiper speed information of the target user under each rainfall environment can be obtained, thereby establishing the wiper sensitivity, improving the matching degree between the target wiper speed and the preferred wiper speed of the target customer, and optimizing the intelligence of the wiper operation.

[0066] Step S104, determining a target wiper speed based on current rainfall information and a wiper sensitivity model.

[0068] Through the above steps, a wiper sensitivity model of the target user can be established according to the wiper speed selected by the target user. The target wiper speed can be determined by 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 requirements of the target user, thereby improving the user experience of the target user and further solving the technical problem of poor user experience of the wiper system in the prior art.
