[0035] In order to make the purpose, technical solutions and advantages of the present application more clear, the present application will be further described in detail below in combination with specific embodiments and with reference to the drawings.

[0036] It should be noted that, unless otherwise defined, technical terms or scientific terms used in the embodiments of the present application shall have the common meaning understood by one of ordinary skill in the art to which the embodiments of the present application belong.

[0037] Generally, the wiper of an automobile has OFF, intermittent gear, low-speed gear, and high-speed gear. For the case of continuous rain, a driver can select a suitable low-speed gear or high-speed gear according to the rain amount to obtain a better wiping effect. However, for the case of a small amount of rain, the intermittent time of wiping is long, and it is not suitable to select a low-speed gear or a high-speed gear. In this case, an intermittent gear is generally selected. When the wiper is in the intermittent gear, the wiper runs for a cycle, stops for a period of time, and then runs for another cycle, and so on. The time during which the wiper stops in each cycle is the intermittent time.

[0038] In some existing vehicles that are not equipped with an automatic wiper, no rain sensor is configured. When the wiper is in the intermittent gear, the intermittent time of the wiper cannot be adjusted due to reasons such as cost or part universality, and the intermittent time of the wiper is fixed.

[0039] However, in actual use, the driver needs different wiping frequencies and intermittent times of the wiper under different rain amounts, different vehicle speeds, and different vehicle use degrees. The fixed intermittent time cannot meet the actual needs of the user, and the use of the fixed intermittent time can cause the phenomenon of untimely wiping or excessively frequent wiping.

[0040] Therefore, how to dynamically adjust the intermittent time according to the actual needs of the user is a problem to be solved.

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

[0042] In step S100, an initial intermittent time is obtained in response to determining that the wiper gear is in the intermittent gear.

[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 meeting 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, an initial intermittent time is obtained. The initial intermittent time can be the intermittent time of the intermittent gear set by the system by default, or the intermittent time stored in the previous period. For example, the initial intermittent time can be 4s or 5s.

[0045] After obtaining the initial intermittent time, the vehicle controller controls the wiper to perform the wiping operation in the intermittent gear and with the initial intermittent time as the intermittent time, i.e., the wiper runs a cycle, stops for the initial intermittent time, and then runs another cycle, and so on.

[0046] During the wiping operation of the wiper, when at least two wiper gear adjustment instructions are received within a preset time (a preset time threshold), it indicates that the user has continuously adjusted the wiper gear at least twice within the preset time, and further indicates that the user has a demand to adjust the wiper gear at this time, and neither the intermittent gear nor the wiper gear after the first adjustment can meet the user's demand, so the user performs the second wiper gear adjustment.

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

[0048] When it is determined that the at least two wiper gear adjustment instructions do not meet the intermittent time adjustment condition, it indicates 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 the at least two wiper gear adjustment instructions meet the intermittent time adjustment condition, it indicates that the intention of the at least two wiper gear adjustment instructions issued by the user at this time is to adjust the intermittent time, and only adjusting the intermittent time can meet the user's demand, so the intermittent time is adjusted on the basis of the initial intermittent time at this time, and a target intermittent time is finally obtained.

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

[0051] In the present application, when at least two wiper gear adjustment instructions are received within a preset time and the at least two wiper gear adjustment instructions meet the intermittent time adjustment condition, it is indicated that the user has a demand for adjusting the intermittent time. At this time, the vehicle controller can adjust the intermittent time on the basis of the initial intermittent time, and finally obtain the target intermittent time meeting the user's demand. When the wiper intermittent gear is operated with the target intermittent time, the actual demand of the user can be better met, and the user's use convenience is improved.

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

[0053] In response to at least one of the at least two wiper gear adjustment instructions being an instruction to adjust the wiper gear to the intermittent gear, it is determined that the at least two wiper gear adjustment instructions meet the intermittent time adjustment condition.

[0054] Specifically, taking the vehicle wiper having OFF, intermittent gear, low-speed gear and high-speed gear as an example, when no gear adjustment instruction is received, the wiper is in the intermittent gear. Then, when at least two wiper gear adjustment instructions are received, it needs to be noted that:

[0055] Firstly, the adjacent two wiper gear adjustment instructions must be different, otherwise there is no need to perform two gear adjustment instructions.

[0056] Secondly, the first received wiper gear adjustment instruction 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 received wiper gear adjustment instruction can only be an instruction to adjust the wiper to OFF, an instruction to adjust the wiper to the low-speed gear or an instruction to adjust the wiper to the high-speed gear.

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

[0059] When it is determined that at least one of the at least two wiper gear adjustment instructions is an instruction to adjust the wiper gear to the intermittent gear, since the first wiper gear adjustment instruction cannot be the intermittent gear, it is indicated 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 is indicated that the user changes the wiper gear from the initial intermittent gear to another gear (which can be OFF, low-speed gear, and high-speed gear) after the first gear adjustment instruction, and then adjusts the wiper gear back to the intermittent gear. This indicates that neither the intermittent gear nor the other gear after the first adjustment can meet the user's needs. At this time, it is determined that the user has a need to adjust the intermittent time, and it is determined that the at least two wiper gear adjustment instructions meet the intermittent time adjustment condition. The vehicle controller can adjust the intermittent time on the basis of the initial intermittent time to obtain a target intermittent time.

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

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

[0062] After receiving the first wiper gear adjustment instruction, the wiper is controlled to be in the low-speed gear (the wiping frequency of the low-speed gear is greater than that of 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, in the entire control process, the initial intermittent gear cannot meet the user's needs, and the low-speed gear after the first gear adjustment also cannot meet the user's needs. Therefore, the user adjusts the wiper gear to the intermittent gear again. However, it is obvious that adjusting to the intermittent gear still cannot meet the user's needs (otherwise, the user would not need to perform the first gear adjustment). At this time, the wiper cannot meet the user's needs in the intermittent gear and the low-speed gear. Therefore, the vehicle controller needs to adjust the intermittent time on the basis of the initial intermittent time to increase or decrease the intermittent time, so as to meet the actual needs of the user.

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

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

[0067] The step S210 comprises: acquiring vehicle speed information of the vehicle.

[0068] The step S220 comprises: in response to the vehicle speed information being greater than or equal to a preset vehicle speed threshold, determining an adjustment time, and determining the target intermittent time based on the initial intermittent time and the adjustment time.

[0069] The step S230 comprises: in response to the vehicle speed information being less than the preset vehicle speed threshold, determining the initial intermittent time as the 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 acquired first.

[0071] When the vehicle speed information is greater than or equal to the preset vehicle speed threshold, it indicates that the vehicle speed is relatively large at this time, and the wiping frequency of the wiper will have a significant impact on the user, and even affect the driving safety. At this time, the adjustment time of the intermittent time needs to be further determined, and then the target intermittent time is determined based on the initial intermittent time and the adjustment time, so as to ensure that the final target intermittent time meets the user's demand.

[0072] When the vehicle speed information is less than the preset vehicle speed threshold, it indicates that the vehicle speed is relatively small at this time, and the wiping frequency of the wiper will not have a significant impact on the user, and will not affect the driving safety. Therefore, at this time, the initial intermittent time is determined as the target intermittent time, which can reduce unnecessary operations and reduce the energy consumption of the vehicle.

[0073] The preset vehicle speed threshold is a preset maximum threshold of the vehicle speed. When the vehicle speed information is less than the preset vehicle speed threshold, it indicates that the vehicle speed is relatively small, and the wiping 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 indicates that the vehicle speed is relatively large, and the wiping frequency has a greater effect 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 determination methods of the target intermittent time are adopted based on different vehicle speed information, so that the finally determined target intermittent time can meet the actual needs of the user, and unnecessary operations can be reduced, and the energy consumption of the vehicle can be reduced.

[0075] In some embodiments, the step S220 of determining the adjustment time comprises:

[0076] The step S221 comprises: acquiring the total number of operations of the wiper and / or the environmental humidity.

[0077] In step S222, a wear coefficient of the wiper is determined based on the total number of operations, and / or a humidity coefficient is determined based on the ambient humidity.

[0078] In step S223, a preset adjustment value is added to the sum of the wear coefficient and / or the humidity coefficient to determine the adjustment time.

[0079] Specifically, in determining the adjustment time, the wear degree of the wiper and the humidity of the external environment need to be considered in order to make the finally determined target intermittent time more accurate. Because the more serious the wear of the wiper is, the longer the time required for the wiper to brush once is relative to the wiper without any wear, the wear degree of the wiper is closely related to the brushing time of the wiper. In addition, the different ambient humidity also affects the brushing time of the wiper. The greater the humidity is, the smaller the friction of the wiper when brushing is, and the shorter the time for the wiper to brush once is.

[0080] Therefore, in determining the adjustment time, the total number of operations of the wiper and / or the ambient humidity are obtained. The total number of operations of the wiper is positively correlated with the wear degree of the wiper. The more the total number of operations of the wiper is, the more serious the wear degree of the wiper is.

[0081] In specific implementation, the total number of operations of the wiper that has been stored can be obtained from the storage space of the vehicle. The ambient humidity can also be obtained by controlling the humidity sensor of the vehicle.

[0082] Then, based on the total number of operations, a wear coefficient of the wiper 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, a preset adjustment value is added to the sum of the wear coefficient and / or the humidity coefficient to determine the adjustment time. The preset adjustment value is an empirical value of the intermittent time adjustment obtained according to actual test experience. Exemplarily, the preset adjustment value can be 0.5s or 1s, etc.

[0084] In specific implementation, according to actual conditions, the sum of the preset adjustment value, the wear coefficient and the humidity coefficient can be determined as the adjustment time, or the sum of the preset adjustment value and the wear coefficient can be determined as the adjustment time, or the sum of the preset adjustment value and the humidity coefficient can be determined as the adjustment time, so that the finally determined adjustment time is more accurate.

[0085] In the present application, when determining the adjustment time, not only the preset empirical value is considered, but also the actual influencing factors (i.e., the wear degree of the windscreen wiper and the influence of the environmental humidity) that affect the operation of the windscreen wiper are considered, so that the adjustment time determined based on the preset adjustment value, the wear coefficient and / or the 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 of determining the target intermittent time based on the initial intermittent time and the adjustment time includes:

[0088] Step S224, in response to the at least two windscreen wiper gear adjustment instructions meeting the increase intermittent time condition, 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 windscreen wiper gear adjustment instructions meeting the decrease intermittent time condition, determining the difference between the initial intermittent time and the adjustment time as the target intermittent time.

[0090] Specifically, the increase intermittent time condition is a preset condition that requires an increase in intermittent time. When the at least two windscreen wiper gear adjustment instructions meet the increase intermittent time condition, it indicates that the actual needs of the user determined based on the at least two windscreen wiper gear adjustment instructions are to increase the intermittent time, and thus the sum of the initial intermittent time and the adjustment time is determined as the target intermittent time to increase the adjustment time based on the initial intermittent time, so that the finally determined target intermittent time is the intermittent time after the increase, which better meets the actual needs of the user.

[0091] The decrease intermittent time condition is a preset condition that requires an increase in intermittent time. When the at least two windscreen wiper gear adjustment instructions meet the decrease intermittent time condition, it indicates that the actual needs of the user determined based on the at least two windscreen wiper gear adjustment instructions are to decrease the intermittent time, and thus the difference between the initial intermittent time and the adjustment time is determined as the target intermittent time to decrease the adjustment time based on the initial intermittent time, so that the finally determined target intermittent time is the intermittent time after the decrease, which better meets the actual needs of the user.

[0092] In the present application, based on at least two wiper gear adjustment instructions, it is judged whether the actual intention of the user is to increase the interval time or to reduce the interval time, and then based on the judgment result, the initial interval time is increased or reduced to obtain the final target interval time, so that the obtained target interval time is more in line with the actual needs of the user.

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

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

[0095] Specifically, the wiper wiping frequency of the first gear is less than the wiper wiping frequency of the intermittent gear, and exemplarily, the first gear can be the OFF gear.

[0096] Since at least one instruction in the at least two wiper gear adjustment instructions adjusts the wiper gear to the intermittent gear, if at least one instruction in the at least two wiper gear adjustment instructions adjusts the wiper gear to the first gear, it means that at this time the user adjusts the wiper gear from the original intermittent gear to the first gear (wiper wiping frequency is reduced), and then to the intermittent gear. That is, the initial intermittent gear cannot meet the user's needs, the user adjusts the wiper gear to the first gear with smaller wiper wiping frequency, which cannot meet the user's needs, and the user adjusts the wiper to the original intermittent gear, which still cannot meet the user's needs.

[0097] Then, by repeatedly adjusting the user between the intermittent gear and the first gear with smaller wiper wiping frequency, it can be determined that the interval time of the intermittent gear is too short, that is, the wiper wiping frequency is too large, and the user wants to reduce the wiper wiping frequency. However, when the wiper is adjusted to the first gear with reduced 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 wiper wiping frequency of the intermittent gear and the wiper wiping frequency of the first gear. At this time, the interval time needs to be adjusted to appropriately increase the interval time to reduce the wiper wiping frequency, so that the wiping frequency can meet the user's needs.

[0098] In the present application, when at least one of the at least two wiper gear adjustment instructions is to adjust the wiper gear to the first gear, it is determined that the actual demand of the user is to increase the intermittent time based on the gear adjustment instruction, and it is determined that the at least two wiper gear adjustment instructions meet the increase intermittent time condition. The adjustment time can be increased based on the initial intermittent time, so that the target intermittent time obtained finally meets the actual demand of the user.

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

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

[0101] Specifically, the wiper wiping frequency of the second gear is greater than the wiper wiping frequency of the intermittent gear. For example, the second gear can be a low-speed gear.

[0102] Since at least one of the at least two wiper gear adjustment instructions is to adjust the wiper gear to the intermittent gear, if at least one of the at least two wiper gear adjustment instructions is to adjust the wiper gear to the second gear, it indicates that the user adjusts the wiper gear from the original intermittent gear to the second gear (the wiper wiping frequency is increased), and then to the intermittent gear. That is, the initial intermittent gear cannot meet the user's demand, the user adjusts the wiper gear to the first gear with a larger wiper wiping frequency, but still cannot meet the user's demand, and the user adjusts the wiper gear to the original intermittent gear, but still cannot meet the user's demand.

[0103] Therefore, by repeatedly adjusting the wiper gear between the intermittent gear and the second gear with a larger wiper wiping frequency, it can be determined that the intermittent time of the intermittent gear is too long, i.e. the wiper wiping frequency is too small, and the user wants to increase the wiper wiping frequency. However, when the wiper gear is adjusted to the third gear with an increased wiper wiping frequency, the wiper wiping frequency is too large and cannot meet the user's demand. At this time, the user needs a wiper wiping frequency between the wiper wiping frequency of the intermittent gear and the wiper wiping frequency of the second gear. Therefore, at this time, the intermittent time needs to be adjusted to appropriately reduce the intermittent time to increase the wiper wiping frequency, so that the wiper wiping frequency can meet the user's demand.

[0104] In the present application, when the at least two wiper gear adjustment instructions include at least one instruction of adjusting the wiper gear to the second gear, the at least two wiper gear adjustment instructions meet the intermittent time reduction condition, and the actual demand of the user is determined to be to reduce the intermittent time based on the gear adjustment instruction. The adjustment time can be reduced based on the initial intermittent time, so that the final target intermittent time meets the actual demand of the user.

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

[0106] obtaining rainfall information and vehicle speed information of the vehicle;

[0107] obtaining the initial intermittent time from a preset intermittent time storage based on the rainfall information and the vehicle speed information.

[0108] Specifically, as described above, the initial intermittent time can be the intermittent time of the intermittent gear set by the system by default, or can be the previously stored intermittent time.

[0109] When the initial intermittent time is the previously stored intermittent time, the process of obtaining the initial intermittent time comprises: obtaining rainfall information and vehicle speed information of the vehicle. The rainfall information can be obtained by a vehicle-mounted weather forecast, or can be obtained by a cloud-based weather forecast.

[0110] The rainfall information can include no rain, light rain, moderate rain, heavy rain, and heavy rain.

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

[0112] In the present application, the preset intermittent time storage is configured in the vehicle in advance, and different initial intermittent times are preset for different rainfall information and different vehicle speed information. In this way, the initial intermittent time can be more in line with the actual situation, and the target intermittent time obtained by further adjustment based on the initial intermittent time which is more in line with the actual situation can be more in line with the actual demand of the user, thereby improving the user's convenience.

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

[0114] The intermittent time of the vehicle is generally defined as a default value (exemplarily, the default value can be 4s) when the wiper gear is set to the intermittent gear, and the intermittent time is dynamically adjusted and stored according to the driver ID and use habit, weather condition, vehicle speed and the like after the vehicle is delivered, so as to meet the different requirements of the user for the intermittent time under different use conditions. The specific strategy is as follows:

[0115] (1) The different IDs of the driver are determined by the vehicle system, and the current weather condition provided by the vehicle system is classified into no rain, light rain, moderate rain, heavy rain and heavy rain. The vehicle speed is classified with 10km / h as a scale, and 20-30km / h is recorded as 30km / h. The intermittent value of each driver ID, different weather condition and different vehicle speed is stored in the internal storage space of the controller (i.e. the preset intermittent time storage library is pre-configured), and each different state corresponds to a different T value, T being the stored intermittent time. For example: (ID1, light rain, 30km / h) corresponds to T1, and the following takes T1 as an example to dynamically adjust the intermittent time.

[0116] (2) When the vehicle speed is greater than or equal to 5km / h and the engine is running or the high voltage of the electric vehicle is on, the stored intermittent time strategy is dynamically adjusted:

[0117] When it is detected that the wiper gear is switched from the intermittent gear to the low speed gear (i.e. the second gear mentioned above) twice within twice (T1+2)s (i.e. the preset time), (i.e. at least two wiper gear adjustment instructions include an instruction to adjust the wiper gear to the intermittent gear, and also include an instruction to adjust the wiper gear to the second gear), T1 is reduced by t time. The calculation method of t time is: t=0.5s+k1+k2 (k1 is the current wear coefficient of the wiper, which can be calculated according to the total number of wiper operations stored, and the greater the wear degree, the smaller k1; K2 is the current air humidity coefficient, which can be determined according to the environmental humidity collected by the humidity sensor of the vehicle, and the greater the humidity, the greater the value of k2; 0.5s is an empirical value).

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

[0119] 3) The latest T1 calculated is compared with the stored T1 value obtained, if they are inconsistent, the stored T1 value is updated, and the intermittent time is executed according to the latest calculated T1, so as to meet the requirements of the user for the intermittent time.
