It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be further noted that, for the convenience of description, only some of the structures related to the present invention are shown in the drawings, not all of the structures.
Example one
Fig. 1 is a flowchart of a method for controlling a wiper of an automobile according to an embodiment of the present invention, where the embodiment is applicable to a wiper speed control situation of a wiper of an automobile, and the method can be executed by an automobile wiper control device, and specifically includes the following steps:
and 110, detecting the rainfall of rainwater on a windshield, wherein a wiper is arranged on the windshield.
The windscreen wiper is also called as a windshield wiper, a water wiper or a windshield wiper and is used for sweeping rain, snow and dust which obstruct the sight on the windshield, improving the visibility of a driver and increasing the driving safety. The wiper is arranged in front of the windshield and consists of a motor, a speed reducer, a four-bar mechanism, a wiper arm mandrel, a wiper blade assembly and the like. The speed of the motor is mainly controlled to control the wiper, so that the working speed of the wiper is changed, and different wiping amounts are realized. Besides automobiles, other transportation means are also provided with a wiper, such as trains and trams. In addition, it should be noted that the automobile wiper control method provided in the embodiment of the present invention is not limited to be used in automobiles, and may be used in other places where wipers are installed.
In the present embodiment, the amount of rain of rainwater hitting the windshield is mainly detected. In automobiles, rainfall information is collected mainly by a rainfall sensor for detecting the rainfall on the windshield. Common rainfall sensors mainly comprise a capacitance type rainfall sensor, a piezoelectric type rainfall sensor and an infrared type raindrop sensor. The working principle and the rain detection method of each type of rain sensor are well known in the art, and the embodiment of the invention is not described herein again.
In the embodiment of the present invention, the wiper device may be disposed in a body Control module bcm (body Control module) of the vehicle or integrated in a rain sensor rls (rain Light sensor). The body Control module bcm (body Control module) is a Control module on the automobile, and is used for realizing discrete functions of light Control, wiper (washing) Control, door lock Control and the like so as to meet the increasing requirements of people on safety, comfort and the like.
And 120, inquiring the current wiping speed grade of the wiper.
In the present embodiment, the wiping speed of the wiper is divided into several speed levels according to different speed levels or ranges. That is, different speed classes correspond to different wiping speeds, the wiping speed of the wiper blade at the corresponding speed class corresponds to a set speed, and the wiping speed corresponding to the speed class is kept running to wipe the rainwater on the windshield.
In one specific embodiment, 8 speed levels are set. The first grade corresponds to a stop state, namely the wiper under the first grade is in the stop state. The second grade to the eighth grade correspond to different speed values respectively, and the wiping speed of the windscreen wiper increases progressively from the second grade to the eighth grade.
In this embodiment, the current speed grade query mode of the wiper may be various, and for example, the current speed grade of the wiper may be obtained directly from a body control module of the automobile, or the current speed of the wiper may be obtained to judge the current speed grade of the wiper. In addition, other forms of query modes that meet the use requirements of the embodiments of the present invention are also possible, and are not listed in detail here.
Step 130, determining a rainfall range suitable for driving a wiper to wipe by applying the speed represented by the speed grade;
in the embodiment of the invention, the rainfall of the rain on the windshield is obtained by detection in step 110, and different rainfall degrees correspond to different rainfall amounts, and the wiping capacities of the wipers running at different speed levels are different. Therefore, in the present embodiment, the rainfall ranges are set for different rainfall size ranges, and the rainfall ranges are matched with the speed class to which the required wiper speed belongs. That is, different rain fall ranges are associated with the speed levels of the wiping speed of the wiper, and the different speed levels correspond to the different rain fall ranges and represent different wiping capabilities. Likewise, different rain ranges correspond to different speed classes, which represent different wiping capacities.
Step 140, when the rain fall is not appropriate for the rain fall range, adjust a speed level of the wiper toward the rain fall.
In this embodiment, the current rain amount detected in step 110 is compared with the rain amount range corresponding to the current speed level of the wiper determined in step 130, and if the detected rain amount does not fall within the rain amount range corresponding to the current speed level of operation, the speed representing the current operation of the wiper does not match the current rain amount of rain, and at this time, the speed level of the wiper is adjusted toward the detected rain amount, so that the rain amount range corresponding to the speed level of the operation of the wiper is adjusted toward the detected rain amount by one speed level, thereby completing an adjustment operation. When the detected rainfall is not suitable for the speed grade of the wiper, adjusting a speed grade towards the detected rainfall, then returning to the step S110 to detect the rainfall after adjusting the speed grade, comparing the rainfall with the rainfall range corresponding to the adjusted speed grade, and finally adjusting the speed grade of the wiper according to the comparison result, so that the detection, comparison and adjustment work is continuously and circularly carried out, and the successive detection and the gradual adjustment on the conditions of different rainfall sizes are finished.
In the method for controlling the automobile wiper provided by the embodiment, the current rainfall on the windshield of the automobile is obtained through real-time detection, so that the timeliness of the detection of the rainfall and the adjustment of the wiper are ensured; then, the current speed grade of the wiper of the automobile and the corresponding rainfall range are inquired and determined, and whether the detected rainfall is matched with the current speed grade of the wiper and the corresponding rainfall range or not is determined according to the comparison result of the detected rainfall and the speed grade of the wiper, namely whether the water wiping capacity of the current speed grade of the wiper is matched with the current rainfall or not is determined. When the detected rainfall is not matched with the current speed grade of the windscreen wiper, the speed grade is adjusted up or down or not adjusted according to the comparison result of the detected rainfall and the rainfall range corresponding to the current speed grade, then the rainfall on the windshield of the automobile at the next moment is returned to be detected again, and the rainfall is compared with the rainfall range corresponding to the adjusted speed grade to judge whether readjustment is needed or not. Through detecting one by one, adjust the speed grade of windscreen wiper step by step, make when adjusting the speed of windscreen wiper, there is certain adjustment time interval between the adjacent speed grade, when avoiding once adjusting the speed grade of windscreen wiper to the speed grade that corresponds with current rainfall, great speed span brought, avoid the too fast problem of speed change rate of speed adjustment in-process windscreen wiper, and avoid when the rainfall change is undulant great, the running speed of frequent many times adjustment windscreen wiper by a wide margin, and the speed that brings when frequent adjustment is beated by a wide margin, and then optimize user experience, slow down the wearing and tearing damage speed of the moving part of windscreen wiper.
Example two
A second embodiment of the present invention provides another method for controlling a wiper of an automobile, and fig. 2 is a flowchart of the method for controlling the wiper of the automobile according to the second embodiment of the present invention, which is detailed based on the first embodiment, and describes a data processing procedure in detail, as shown in fig. 2, the method includes:
step 201, detecting the rainfall of rainwater on a windshield, wherein a wiper is arranged on the windshield;
in this embodiment, the rain amount detection of the rain on the windshield is basically similar to the detection manner in step 110 in the first embodiment, as long as the rain amount on the windshield can be detected, and the relevant points refer to the description in the first embodiment, and the embodiments of the present invention are not described in detail herein.
Optionally, the rainfall sensor detects the rainfall at a certain time, and only represents the instantaneous rainfall during detection. In order to avoid the influence of errors and fluctuation caused by instantaneous rainfall at a single moment on the judgment of the automobile wiper control device, the average value of the instantaneous rainfall collected at several continuous moments can be calculated to serve as the current rainfall.
In addition, the rainfall can be detected in other modes, so that the speed change of a wiper of the automobile caused by the instantaneous change of the rainfall is avoided, the speed adjustment of the wiper is frequent, the beating frequency of the wiping brush is too high, the speed change of the wiper becomes abrupt, and the influence on the normal experience of a user is avoided.
Step 202, inquiring the current wiping speed grade of the wiper;
in the present embodiment, the speed grade of the wiper is obtained in a manner substantially similar to the inquiry manner in the first embodiment, and reference may be made to relevant contents in the first embodiment, and the embodiment of the present invention will not be described in detail herein.
Optionally, the speed rating of the wiper is positively correlated to the speed of the wiper. The first grade corresponds to a stop state, namely the windscreen wipers under the first grade are in the stop state, and the speeds of the speed grades after the first grade are sequentially increased.
Step 203, acquiring a corresponding relation table of a speed grade and a rainfall range from a vehicle body controller of the vehicle, wherein the speed grade is positively correlated with the rainfall range;
a body controller bcm (body Control module), also called a body computer (body computer), of an automobile is one of important components of an automobile, which is an Electronic Control Unit (ECU) for controlling electrical systems of the body in automobile engineering. The device is mainly used for receiving information input by a sensor or other devices and converting the input information into signals capable of being received by a microprocessor; storing, calculating, analyzing and processing information, analyzing programs for output values, storing characteristic parameters of the vehicle type, data in operation (random access), storing fault information and the like. The corresponding relation table of the speed grade and the rainfall range required in the embodiment can be stored in the vehicle body controller, the corresponding relation table can be preset and stored in the storage unit of the vehicle body controller, and required contents can be directly extracted from the storage unit when the relation between the speed grade and the rainfall range of the windscreen wiper needs to be acquired.
In the present embodiment, the rainfall range is designated as a rainfall size range, and the rainfall range is set mainly according to the wiper wiping capability of the wiper at the corresponding speed level. Along with the improvement of the speed grade, the faster the running speed of the wiper is, the stronger the water wiping capability of the corresponding wiper is, the more the amount of the rainwater which can be wiped away by the wiper in unit time is, and the range of the rainwater which can be wiped away by the wiper at different speed grades is divided into continuous rainfall intervals, namely the rainfall range in the embodiment.
And step 204, extracting a corresponding rainfall range from the corresponding relation table according to the speed grade.
In the present embodiment, the speed class of the current wiper operation obtained by the query in step 202 is used as a key to find the rainfall range corresponding to the speed class from the correspondence table stored in the storage unit. The specific query method is well known in the art and will not be described herein.
Step 205, comparing the rainfall with the rainfall range;
if the rainfall is greater than the rainfall range, go to step 206;
if the rainfall is smaller than the rainfall range, go to step 211;
if the rainfall is equal to the rainfall range, the process returns to step 201.
The detected rainfall is compared with a rainfall range, wherein the rainfall range is a range value, and the rainfall is compared with the maximum value and the minimum value of the rainfall range respectively. If the rainfall is greater than the maximum value of the rainfall range, go to step 206; if the rainfall is smaller than the minimum value of the rainfall range, step 207 is executed; if the rainfall is greater than or equal to the minimum value of the rainfall range and less than or equal to the maximum value of the rainfall range, that is, the current rainfall is adapted to the rainfall range, the step 201 is executed again.
Step 206, judging whether the current speed grade is a first grade or not, wherein the speed of the wiper under the first grade is zero;
if yes, go to step 207;
if not, go to step 210;
step 207, acquiring the sensitivity level selected by the operating handle of the automobile, wherein the sensitivity level corresponds to different interval time;
208, determining the interval time of the wiper with the speed grade of the second grade according to the sensitivity grade;
and step 209, adjusting the windscreen wiper to enter a second level, and wiping the windscreen at intervals according to the interval time.
In the prior art, when the rainfall is small, the mode of intermittent point scraping/intermittent periodic scraping is set, that is, the windshield wiper of the automobile is intermittently brushed on the windshield of the automobile, but the periodic scraping is not continuous.
In the embodiment of the present invention, in step 205, the rainfall is compared with the rainfall range, and when it is determined whether the rainfall matches the rainfall range, it is further determined whether the current speed level of the wiper is at the first level (stop state), and if so, the intermittent wiping mode is started. The automobile is provided with an operating handle for controlling the sensitivity of the windscreen wiper, different gears are selected to correspond to different sensitivity levels, different sensitivity levels correspond to different time intervals, and the windscreen wiper can be used for wiping the windshield of the automobile according to the time intervals corresponding to the selected sensitivity levels when the windscreen wiper runs at the speed level of the second level.
Step 210, adjusting the wiper to enter the next speed grade, and returning to execute the step 201;
and step 211, adjusting the wiper to enter the previous speed grade, and returning to execute step 201.
In the present embodiment, when the currently detected rainfall is not suitable for the rainfall range of the current speed level of the wiper, the speed level of the wiper needs to be adjusted so that the current rainfall can be matched with the speed level of the wiper.
Further, when the detected current rainfall is greater than the rainfall range corresponding to the current speed level of the wiper, it is indicated that the current rainfall is greater than the maximum water wiping capability of the wiper running at the current speed level, and the water wiping speed of the wiper needs to be increased, so as to further improve the water wiping capability of the wiper. I.e. the speed level of the wiper needs to be adjusted into the next faster speed level. That is, when the wiping capability of the speed class of the wiper is insufficient, the operation speed of the wiper needs to be adjusted to the next higher speed class, and after adjusting one speed class, the process returns to step 201, and the amount of rain falling on the windshield of the automobile at the time when the speed class of the wiper is adjusted is detected again.
The step 201 is executed again after the speed grade of the wiper is adjusted every time, and the rainfall on the windshield of the automobile at the moment after the speed grade of the wiper is adjusted is detected again, so that when the speed of the wiper is adjusted, a certain adjusting time interval exists between adjacent speed grades, the problem that when the speed grade of the wiper is adjusted to the speed grade corresponding to the current rainfall once, the large speed span is caused is avoided, the problem that the speed change rate of the wiper is too high in the speed adjusting process is solved, the problem that when the rainfall change fluctuation is large, the running speed of the wiper is frequently and repeatedly adjusted greatly, and the speed caused by frequent adjustment is greatly increased is avoided, the user experience is optimized, and the abrasion damage speed of moving parts of the wiper is reduced.
In addition, when the detected current rainfall is smaller than the rainfall range corresponding to the current speed level of the wiper, it is indicated that the current rainfall is smaller than the wiping capability of the wiper running at the current speed level, and the wiping speed of the wiper needs to be reduced to ensure the normal operation of the wiper. When the detected current rainfall is equal to the rainfall range corresponding to the current speed level of the wiper, it is indicated that the wiping capability of the wiper operating at the current speed level is adapted to the current rainfall without adjustment, and the process directly returns to execute step 201 to detect the rainfall on the windshield again.
Specifically, step 210 adjusts the wiper to enter the next speed level, and returns to step 201, including:
step 2101, the windscreen wiper is adjusted to enter the next speed grade through the transition grade, and the speed of the windscreen wiper under the transition grade is between the speed of the windscreen wiper of the current speed grade and the speed of the windscreen wiper of the next speed grade.
In this embodiment, before the speed of the wiper is adjusted from the current speed level to the next higher speed level, the wiper needs to be adjusted to a transition level between the current speed level and the next speed level, and then the wiper needs to be adjusted from the transition level to the next speed level. The aim of the operation is to set up the transition grade between two adjacent speed grades, the speed of the windscreen wiper under the transition grade is between two adjacent speed grades, with the speed variation range of this effectual reduction windscreen wiper, avoid the obvious fluctuation that brings when the speed span between the speed grade is great, make the speed grade adjustment transition of windscreen wiper more smooth-going, avoid the too fast problem of speed change rate of speed adjustment in-process windscreen wiper, and then optimize user experience, slow down the wearing and tearing damage speed of the moving part of windscreen wiper.
It can be known that, in the above manner, only one transition level is set between two adjacent speed levels, and in the actual setting process, a plurality of transition levels can be set, so as to further refine the transition speed change of the wiper between two adjacent speed levels, so that the switching of the wiper between two adjacent speed levels is smoother, the existing feeling of the wiper during the speed level adjustment is reduced, and the dispersion of the attention of a user is reduced.
Further, step 2101 adjusts the wiper through the transition level into the next speed level, including:
step 21011, adjusting the windscreen wiper to enter a transition grade;
step 21012, timing a second time, wherein the second time is more than the time of one week of wiper operation;
step 21013, adjust the wiper to enter the next speed level.
Illustratively, a timer is set in the body controller of the automobile, and the timer is triggered to start timing when the step 21011 is triggered to execute, and the step 21013 is triggered to execute when the timing reaches a second time so as to adjust the speed level of the wiper to the next speed level required to be adjusted.
When the wiping speed grade of the wiper is adjusted, the speed of the wiper is adjusted to a transition grade between the current speed grade and the next speed grade, so that the problem that the speed grade of the wiper is obviously changed due to obvious fluctuation caused by large speed span during adjustment between the speed grades can be solved; and secondly, timing a second time to adjust the speed grade of the wiper to enter the next speed grade after the speed grade of the wiper is adjusted to enter the transition grade, and increasing time pause when the speed grade of the wiper is adjusted to the transition grade, so that the jumping sense of the wiper during the speed grade adjustment can be further reduced, the acceleration of the speed change of the wiper in unit time is reduced, and the speed grade adjustment of the wiper is relatively smoother.
Specifically, the second time is set to be longer than the time of one week of wiper operation, that is, the wiper needs to be kept in the transition level state for at least one week, and then the wiper is adjusted to enter the next speed level.
For example, the second time may be set to be equal to a time for which the wiper operates for three weeks even if the wiper operates for three cycles at an excessive level.
In other embodiments, step 21012 may also be replaced by counting the reciprocal movements of the wiper. Namely, a counter is arranged on the automobile, the counting value is added by 1 when the wiper reciprocates once, and the wiper is adjusted to enter the next transition grade from the transition grade after the set number of times is reached.
In other embodiments, it is also possible to have both timing and counting means present, adjusting the speed level of the wiper into the next speed level after the counting and timing requirements are reached.
And 2102, timing a first time, wherein the first time is more than the time of one week of wiper operation.
Step 2103, return to step 201.
In this embodiment, the execution step 201 is returned again after the first time of delay after the speed grade adjustment of windscreen wiper to next speed grade, gather the rainfall size of hitting on the windshield of car this moment, judge again then whether the rainfall scope that rainfall and the current speed grade of locating of windscreen wiper correspond matches, judge whether need adjust the speed grade of windscreen wiper again, with the effect of scraping off of the rainwater on the windshield of assurance to the car, guarantee driver's the field of vision, and then guarantee the security of auttombilism.
For example, when the wiper is adjusted to enter the previous speed level in step 211, the transition level may also be set with reference to step 210, so that the wiper stays at the transition level for a preset time or runs for a preset period number when entering the previous speed level, and then the wiper is adjusted to enter the previous speed level, so that the speed transition of the wiper during the speed level adjustment is more stable, the obvious speed jump is reduced, the user experience is further optimized, and the wear damage speed of the moving parts of the wiper is reduced. The setting mode is basically the same as that in step 210, and the specific content refers to the content in step 210, which is not described herein again.
