At this time, the intermittent time can be adjusted based on the initial intermittent time, and finally the target intermittent time that meets the user's needs is obtained. The operation of the wiper intermittent gear at this target intermittent time can better meet the user's actual needs and improve the user's convenience. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] In order to make the objectives, technical solutions and advantages of the present application more clearly understood, the present application is further described in detail below in combination with specific embodiments and with reference to the accompanying drawings.

[0036] It should be noted that, unless otherwise defined, the technical terms or scientific terms used in the embodiments of the present application should be the usual meanings understood by people with ordinary skills in the field to which the present application belongs. The "first", "second" and similar words used in the embodiments of the present application do not represent any order, quantity or importance, but are only used to distinguish different components.

"Up", "down", "left", "right" and the like are only used to indicate relative positional relationships. When the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0037] Generally, car wipers are divided into OFF, intermittent gear, low speed gear and high speed gear. In the case of continuous rain, drivers can generally select the appropriate low speed gear or high speed gear according to the amount of rain to obtain a better wiper effect. However, when the amount of rain is small, the interval between wipers is longer, and it is not suitable to select low speed gear or high speed gear. At this time, the intermittent gear is generally selected. When the wiper is in the intermittent gear, the wiper runs a cycle, stops for a period of time, and then runs a cycle again, and it goes back and forth in sequence. The time of stopping in the middle of each cycle is the intermittent time.

[0038] Some existing vehicles equipped with non-automatic wipers are not equipped with rain sensors. When the wipers are in the intermittent gear, the wiper intermittent time cannot be adjusted due to cost or component commonality reasons, and the wiper intermittent time remains fixed.

[0039] However, in actual use, the frequency and interval time of windshield wipers required by drivers are different under different rainfall, different vehicle speeds, and different vehicle usage levels. A fixed interval time cannot meet the actual needs of users, and the use of a fixed interval time may result in untimely wiping or overly frequent wiping.

[0040] Therefore, how to dynamically adjust the interval time according to the actual needs of users is an urgent problem to be solved.

[0041] Based on this, see Figure 1 The present application provides a method for determining the interval time of wipers, which is executed by a vehicle controller and includes the following steps:

[0042] Step S100, in response to determining that the wiper gear is an intermittent gear, obtaining an initial intermittent time;

[0043] Step S200: In response to receiving at least two wiper gear adjustment instructions within a preset time and the at least two wiper gear adjustment instructions meet the intermittent time adjustment condition, determining a target intermittent time based on the initial intermittent time.

[0044] Specifically, when it is determined that the wiper gear is the intermittent gear, the initial intermittent time is obtained. The initial intermittent time may be the intermittent time of the intermittent gear set by the system by default, or may be the intermittent time stored in the previous period. Exemplarily, the initial intermittent time may be 4s or 5s.

[0045] After obtaining the initial intermittent time, the vehicle controller controls the wiper to perform the wiping operation with the intermittent gear and the intermittent time being the initial intermittent time, that is, the wiper runs a cycle, stops after the initial intermittent time, and then runs another cycle, repeating in sequence.

[0046] During the wiping operation of the wiper, when at least two wiper gear adjustment instructions are received within a preset time (preset time threshold), it means that the user has continuously adjusted the wiper gear at least twice within the preset time, which further indicates that the user needs to adjust the wiper gear, and the intermittent gear and the wiper gear after the first adjustment cannot meet the user's needs, so the user adjusted the wiper gear for the second time.

[0047] At this time, it is necessary to determine whether at least two wiper gear adjustment instructions meet the intermittent time adjustment condition. The intermittent time adjustment condition is a preset condition that requires the intermittent time to be adjusted.

[0048] When it is determined that at least two wiper gear adjustment instructions do not meet the intermittent time adjustment condition, it means that the intention of the at least two wiper gear adjustment instructions issued by the user at this time is not to adjust the intermittent time, so there is no need to adjust the intermittent time at this time.

[0049] When it is determined that at least two wiper gear adjustment instructions meet the intermittent time adjustment conditions, it means that the user's intention of issuing at least two wiper gear adjustment instructions at this time is to adjust the intermittent time. Only by adjusting the intermittent time can the user's needs be met. At this time, the intermittent time is adjusted based on the initial intermittent time, and finally the target intermittent time is obtained.

[0050] After the target intermittent time is obtained, the target intermittent time can be stored, and then the vehicle controller controls the wiper to perform the wiping operation with the intermittent gear and the intermittent time being the target intermittent time.

[0051] In the present application, when at least two wiper gear adjustment instructions are received within the preset time and at least two wiper gear adjustment instructions meet the intermittent time adjustment conditions, it means that the user has the need to adjust the intermittent time. At this time, the vehicle controller can adjust the intermittent time based on the initial intermittent time, and finally obtain the target intermittent time that meets the user's needs. When the wiper intermittent gear is operated at this target intermittent time, it can better meet the user's actual needs and improve the user's convenience.

[0052] In some embodiments, the method further comprises:

[0053] In response to at least one instruction for adjusting the wiper gear to the intermittent gear among the at least two wiper gear adjustment instructions, it is determined that the at least two wiper gear adjustment instructions meet the intermittent time adjustment condition.

[0054] Specifically, taking the example that the vehicle wiper has OFF, intermittent gear, low speed gear and high speed gear, when no gear adjustment command is received, the wiper is in the intermittent gear. Then, when at least two wiper gear adjustment commands are received, it is necessary to pay attention to:

[0055] First, the two adjacent wiper gear adjustment instructions must be different, otherwise there is no need to issue two gear adjustment instructions;

[0056] Secondly, the first wiper gear adjustment instruction received must not be an instruction to adjust the wiper gear to the intermittent gear, because the initial gear of the wiper is the intermittent gear.

[0057] Then, the first wiper gear adjustment instruction received can only be to adjust the wiper to OFF, to adjust the wiper to a low gear, or to adjust the wiper to a high gear.

[0058] When it is determined that the at least two wiper gear adjustment instructions include at least one instruction to adjust the wiper gear to the intermittent gear, it means that the user changes the wiper gear from the initial intermittent gear to another gear (which can be OFF, low gear and high gear) after the first gear adjustment instruction.

[0059] When it is determined that the at least two wiper gear adjustment instructions include at least one instruction to adjust the wiper gear to the intermittent gear, since the first wiper gear adjustment instruction cannot be an intermittent gear, it means that at least one of the second or subsequent wiper gear adjustment instructions is an instruction to adjust the wiper gear to the intermittent gear. At this time, it means that the user changed the wiper gear from the initial intermittent gear to another gear (which can be OFF, low gear and high gear) after the first gear adjustment instruction, and then adjusted it back to the intermittent gear. This shows that the intermittent gear and the other gear after the first adjustment cannot meet the user's needs. At this time, it is determined that the user has the need to adjust the intermittent time, and it is determined that the at least two wiper gear adjustment instructions meet the intermittent time adjustment conditions. The vehicle controller can adjust the intermittent time based on the initial intermittent time to finally obtain the target intermittent time.

[0060] Exemplarily, it is taken as an example that two wiper gear adjustment instructions are received within a preset time, and the first wiper gear adjustment instruction is to adjust the wiper gear to a low gear, and the second wiper gear adjustment instruction is to adjust the wiper gear to an intermittent gear.

[0061] When no wiper gear adjustment command is received, the wiper is in the intermittent gear.

[0062] After receiving the first wiper gear adjustment command, control the wiper to the low gear (the wiping frequency of the low gear is greater than the intermittent gear).

[0063] Then, the second wiper gear adjustment instruction is received, and the wiper is controlled to return to the intermittent gear again.

[0064] That is to say, during the entire control process, the initial intermittent gear cannot meet the user's needs, and the low-speed gear after the first gear adjustment cannot meet the user's needs, so the user adjusts the wiper gear to the intermittent gear again, but it is obvious that adjusting to the intermittent gear still cannot meet the user's needs (otherwise the user would not need to make the first gear adjustment). At this time, the wiper cannot meet the user's needs in both the intermittent gear and the low-speed gear. At this time, the vehicle controller needs to adjust the intermittent time, increasing or decreasing the intermittent time based on the initial intermittent time to meet the user's actual needs.

[0065] In the present application, when it is determined that the at least two wiper gear adjustment instructions include at least one instruction to adjust the wiper gear to the intermittent gear, it is determined based on the gear instruction that the current initial intermittent time cannot meet the user's time requirements, and the user has the intention to adjust the intermittent time. At this time, it is determined that at least two wiper gear adjustment instructions meet the intermittent time adjustment conditions. The vehicle controller can adjust the intermittent time based on the initial intermittent time, so that the final target intermittent time can meet the user's actual needs.

[0066] In some embodiments, determining the target intermittent time based on the initial intermittent time in step S200 includes:

[0067] Step S210, obtaining vehicle speed information;

[0068] Step S220: In response to the vehicle speed information being greater than or equal to a preset vehicle speed threshold, determining an adjustment time, and determining a target intermittent time based on the initial intermittent time and the adjustment time;

[0069] Step S230: In response to the vehicle speed information being less than a preset vehicle speed threshold, determining the initial intermittent time as a target intermittent time.

[0070] Specifically, when determining the target intermittent time based on the initial intermittent time, the vehicle speed information of the vehicle is firstly acquired.

[0071] When the vehicle speed information is greater than or equal to the preset vehicle speed threshold, it means that the vehicle speed is relatively high at this time. The wiping frequency of the wipers will have a significant impact on the user and may even affect driving safety. At this time, it is necessary to further determine the adjustment time of the intermittent time, and then determine the target intermittent time based on the initial intermittent time and the adjustment time to ensure that the final target intermittent time meets user needs.

[0072] When the vehicle speed information is less than the preset speed threshold, it means that the vehicle speed is relatively low at this time, and the wiping frequency of the wipers will not have a significant impact on the user, nor will it affect driving safety. Therefore, there is no need to adjust the intermittent time at this time, and the initial intermittent time can be determined as the target intermittent time. This can reduce unnecessary operations and reduce the energy consumption of the vehicle.

[0073] The preset vehicle speed threshold is a maximum threshold of the vehicle speed that is pre-set. When the vehicle speed information is less than the preset vehicle speed threshold, it means that the vehicle speed is low and the wiper frequency has little effect on the driving safety of the vehicle. When the vehicle speed information is greater than or equal to the preset vehicle speed threshold, it means that the vehicle speed is high and the wiper frequency has a greater impact on the driving safety of the vehicle.

[0074] In the present application, in the process of determining the target intermittent time based on the initial intermittent time, different methods of determining the target intermittent time are adopted based on different vehicle speed information, so that the final target intermittent time can not only meet the actual needs of the user, but also reduce unnecessary operations and reduce the energy consumption of the vehicle.

[0075] In some embodiments, determining the adjustment time in step S220 includes:

[0076] Step S221, obtaining the total number of wiper operation times and / or ambient humidity;

[0077] Step S222: determining a wiper wear coefficient based on the total number of operations, and / or determining a humidity coefficient based on the ambient humidity;

[0078] Step S223: Determine the sum of the preset adjustment value and the wear coefficient and / or the humidity coefficient as the adjustment time.

[0079] Specifically, when determining the adjustment time, in order to make the final target intermittent time more accurate, it is necessary to consider the degree of wear of the wiper and the humidity of the external environment. Because compared with a wiper without any wear, the more severe the wear of the wiper, the longer it takes for the wiper to wipe once, so the degree of wear of the wiper is closely related to the wiper wiping time. In addition, the difference in environmental humidity will also affect the wiper wiping time. The higher the humidity, the smaller the friction when the wiper wiping, and the shorter the wiper wiping time.

[0080] Therefore, the present application obtains the total number of wiper operation times and / or ambient humidity when determining the adjustment time. The total number of wiper operation times is positively correlated with the degree of wiper wear. The more total number of wiper operation times, the more serious the wiper wear.

[0081] In specific implementation, the total number of wiper operation times stored can be obtained from the storage space of the vehicle. The vehicle humidity sensor can also be controlled to obtain the ambient humidity.

[0082] Then, based on the total number of operations, a wiper wear coefficient corresponding to the total number of operations is determined from a pre-stored wiper wear coefficient table. Based on the ambient humidity, a humidity coefficient corresponding to the ambient humidity is determined from a pre-stored humidity coefficient table.

[0083] Finally, the sum of the preset adjustment value and the wear coefficient and / or the humidity coefficient is determined as the adjustment time. The preset adjustment value is an empirical value of the intermittent time adjustment obtained based on actual test experience. For example, the preset adjustment value can be 0.5s or 1s.

[0084] During specific implementation, depending on the actual situation, the sum of the preset adjustment value, wear coefficient and humidity coefficient can be determined as the adjustment time, or the sum of the preset adjustment value and wear coefficient can be determined as the adjustment time, or the sum of the preset adjustment value and humidity coefficient can be determined as the adjustment time, so that the final adjustment time is more accurate.

[0085] In the present application, when determining the adjustment time, it is not only determined based on the preset empirical value, but also the actual factors affecting the operation of the wiper (i.e., the degree of wiper wear and the influence of ambient humidity) are taken into consideration, so that the adjustment time finally determined based on the preset adjustment value, wear coefficient and / or humidity coefficient is more accurate, and thus the target intermittent time determined based on the adjustment time and the initial intermittent time is more in line with the actual needs of the user.

[0086] In some embodiments, the intermittent time adjustment condition includes an increase intermittent time condition and a decrease intermittent time condition;

[0087] The step S220 determines the target intermittent time based on the initial intermittent time and the adjustment time, including:

[0088] Step S224: in response to the at least two wiper gear adjustment instructions meeting the condition for increasing the intermittent time, determining the sum of the initial intermittent time and the adjustment time as the target intermittent time;

[0089] Step S225: In response to the at least two wiper gear adjustment instructions meeting the intermittent time reduction condition, a difference between the initial intermittent time and the adjustment time is determined as a target intermittent time.

[0090] Specifically, the condition for increasing the intermittent time is a preset condition for increasing the intermittent time. When the at least two wiper gear adjustment instructions meet the condition for increasing the intermittent time, it means that the actual need of the user is to increase the intermittent time based on the at least two wiper gear adjustment instructions. Then, the sum of the initial intermittent time and the adjustment time is determined as the target intermittent time, so that the adjustment time is added on the basis of the initial intermittent time, so that the target intermittent time finally determined is the intermittent time after the increase, which better meets the actual needs of the user.

[0091] The intermittent time reduction condition is a preset condition for increasing the intermittent time. When the at least two wiper gear adjustment instructions meet the intermittent time reduction condition, it means that the actual need of the user is to reduce the intermittent time based on the at least two wiper gear adjustment instructions. At this time, the difference between the initial intermittent time and the adjustment time is determined as the target intermittent time, so as to reduce the adjustment time on the basis of the initial intermittent time, so that the target intermittent time finally determined is the intermittent time after the reduction, which better meets the actual needs of the user.

[0092] In the present application, whether the user's actual intention is to increase or decrease the intermittent time is determined based on at least two wiper gear adjustment instructions, and then the time is adjusted further or less based on the initial intermittent time based on the judgment result to obtain the final target intermittent time, thereby making the obtained target intermittent time more in line with the user's actual needs.

[0093] In some embodiments, the method further comprises:

[0094] In response to at least one instruction to adjust the wiper gear to the first gear among the at least two wiper gear adjustment instructions, it is determined that the at least two wiper gear adjustment instructions meet the condition of increasing the intermittent time; wherein the wiper wiping frequency of the first gear is less than the wiper wiping frequency of the intermittent gear.

[0095] Specifically, the wiper frequency of the first gear is less than the wiper frequency of the intermittent gear. Exemplarily, the first gear may be an OFF gear.

[0096] Since at least one of the at least two wiper gear adjustment instructions includes an instruction to adjust the wiper gear to the intermittent gear, if at least one of the at least two wiper gear adjustment instructions includes an instruction to adjust the wiper gear to the first gear, it means that the user has adjusted the wiper gear from the original intermittent gear to the first gear (wiping frequency is reduced), and then to the intermittent gear. In other words, the initial intermittent gear cannot meet the user's needs, and the user cannot meet the user's needs when the user adjusts the wiper gear to the first gear with a lower wiper frequency. The user adjusts the wiper to the original intermittent gear, and the intermittent gear still cannot meet the user's needs.

[0097] Then, through the user's continuous and repeated adjustment between the intermittent gear and the first gear with a smaller wiper wiping frequency, it can be concluded that the intermittent time of the intermittent gear is too short, that is, the wiper wiping frequency is too large. The user wants to reduce the wiper wiping frequency, but when the wiper is adjusted to the first gear after reducing the wiper wiping frequency, the wiper wiping frequency is too small and cannot meet the user's needs. At this time, the user needs a wiper wiping frequency between the intermittent gear and the first gear. Then, at this time, it is necessary to adjust the intermittent time, appropriately increase the intermittent time to reduce the wiper wiping frequency, so that the wiping frequency can meet the user's needs.

[0098] In the present application, when in response to at least one instruction to adjust the wiper gear to the first gear among the at least two wiper gear adjustment instructions, it is determined based on the gear adjustment instruction that the user's actual need is to increase the intermittent time, and it is determined that the at least two wiper gear adjustment instructions meet the conditions for increasing the intermittent time. The adjustment time can be added on the basis of the initial intermittent time so that the final target intermittent time meets the user's actual needs.

[0099] In some embodiments, the method further comprises:

[0100] In response to at least one instruction to adjust the wiper gear to the second gear among the at least two wiper gear adjustment instructions, it is determined that the at least two wiper gear adjustment instructions meet the condition of reducing the intermittent time; wherein the wiper wiping frequency of the second gear is greater than the wiper wiping frequency of the intermittent gear.

[0101] Specifically, the wiper frequency of the second gear is greater than the wiper frequency of the intermittent gear. Exemplarily, the second gear may be a low speed gear.

[0102] Since at least one of the at least two wiper gear adjustment instructions includes an instruction to adjust the wiper gear to the intermittent gear, if at least one of the at least two wiper gear adjustment instructions includes an instruction to adjust the wiper gear to the second gear, it means that the user has adjusted the wiper gear from the original intermittent gear to the second gear (increased wiper wiping frequency), and then to the intermittent gear. In other words, the initial intermittent gear cannot meet the user's needs, and the user cannot meet the user's needs when the user adjusts the wiper gear to the first gear with a higher wiper wiping frequency. The user adjusts the wiper to the original intermittent gear, and the intermittent gear still cannot meet the user's needs.

[0103] Then, through the user's continuous and repeated adjustment between the intermittent gear and the second gear with a higher wiper wiping frequency, it can be concluded that the intermittent time of the intermittent gear is too long, that is, the wiper wiping frequency is too small. The user wants to increase the wiper wiping frequency, but when the wipers are adjusted to the second gear after increasing the wiper wiping frequency, the wiper wiping frequency is too high and cannot meet the user's needs. At this time, the user needs a wiper wiping frequency between the intermittent gear and the second gear. Then, at this time, it is necessary to adjust the intermittent time, appropriately reduce the intermittent time to increase the wiper wiping frequency, so that the wiping frequency can meet the user's needs.

[0104] In the present application, when in response to at least one instruction to adjust the wiper gear to the second gear among the at least two wiper gear adjustment instructions, it is determined based on the gear adjustment instruction that the user's actual need is to reduce the intermittent time, and it is determined that the at least two wiper gear adjustment instructions meet the conditions for reducing the intermittent time. The adjustment time can be reduced on the basis of the initial intermittent time so that the final target intermittent time meets the user's actual needs.

[0105] In some embodiments, obtaining the initial intermittent time comprises:

[0106] Obtain rainfall information and vehicle speed information;

[0107] Based on the rainfall information and the vehicle speed information, an initial intermittent time is acquired from a preset intermittent time storage library.

[0108] Specifically, as mentioned above, the initial intermittent time may be the intermittent time of the intermittent gear set by the system by default, or may be the intermittent time that has been stored in the previous stage.

[0109] When the initial intermittent time is the stored intermittent time, the process of obtaining the initial intermittent time includes: obtaining rainfall information and vehicle speed information. The rainfall information can be obtained through the vehicle weather forecast, or the weather forecast information can be obtained through the cloud.

[0110] The rainfall information may include no rain, light rain, moderate rain, heavy rain, torrential rain, etc.

[0111] Based on the rainfall information and the vehicle speed information, an initial intermittent time corresponding to the rainfall information and the vehicle speed information is obtained from a preset intermittent time storage library. The preset intermittent time storage library is an intermittent time configuration library pre-stored in the vehicle, and different rainfall information and different vehicle speed information correspond to different initial intermittent times.

[0112] In the present application, a preset intermittent time storage library is pre-configured in the vehicle, and different initial intermittent times are preset for different rainfall information and different vehicle speed information. This can make the initial intermittent time more in line with the actual situation, and then make the target intermittent time further adjusted on the basis of the initial intermittent time that is more in line with the actual situation more in line with the actual needs of the user, thereby improving the user's convenience.

[0113] In some embodiments, the method for determining the wiper intermittent time further includes:

[0114] The vehicle intermittent time is generally defined as a default value when leaving the factory (for example, the default value may be 4s). When the wiper gear is set to the intermittent gear, the wiper will run once every 4s. After leaving the factory, the intermittent time is dynamically adjusted and stored according to the driver ID and usage habits, weather conditions, vehicle speed, etc., to meet the different needs of users for intermittent time under different usage conditions. The specific strategies are as follows:

[0115] (1) The vehicle computer system determines the different IDs of the drivers and classifies the current weather conditions provided by the vehicle computer system into no rain, light rain, moderate rain, heavy rain, and rainstorm. The vehicle speed is classified based on a scale of 10 km / h, and 20-30 km / h is recorded as 30 km / h. Space is allocated in the internal storage space of the controller to store the interval values ​​of each driver ID, different weather conditions, and different vehicle speeds (i.e., a preset interval time storage library is pre-configured). Each different state corresponds to a different T value, where T is the stored interval time. For example: (ID1, light rain, 30 km / h) corresponds to T1. The following takes T1 as an example to dynamically adjust the interval time.

[0116] (2) When the vehicle speed is ≥5 km / h and the engine is running or the electric vehicle is on high voltage, the dynamic adjustment of the stored intermittent time strategy is entered:

[0117] When the wiper gear is detected to be changed from the intermittent gear to the low-speed gear (i.e. the aforementioned second gear) twice within two times (T1+2)s (i.e. the preset time) (i.e. at least two wiper gear adjustment instructions include one instruction to adjust the wiper gear to the intermittent gear and one instruction to adjust the wiper gear to the second gear), T1 is reduced by t time. Calculation method of t time: t=0.5s+k1+k2 (k1 is the current wear coefficient of the wiper, the wear coefficient can be calculated based on the total number of wiper operations stored, the greater the wear degree, the smaller k1; K2 is the current air humidity coefficient, which can be determined based on the ambient humidity collected by the vehicle humidity sensor, the greater the humidity, the greater the k2 value; 0.5s is an empirical value).

[0118] When it is detected that the wiper gear is changed from the intermittent gear to off (i.e. the aforementioned first gear) twice within twice (T1+3)s (i.e. at least two wiper gear adjustment instructions include one instruction to adjust the wiper gear to the intermittent gear and one instruction to adjust the wiper gear to the first gear), T1 is increased by t time.

[0119] 3) Compare the latest calculated T1 with the stored T1 value. If they are inconsistent, update the stored T1 value and execute the interval time according to the latest calculated T1 to ensure that the user's requirements for the interval time are met.
