Detailed Description

Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to like or similar elements or elements having like or similar functions throughout. The embodiments described below by referring to the drawings are illustrative and intended to explain the present invention and should not be construed as limiting the invention.

Fig. 1 is a schematic flowchart of a control method of a wiper according to one embodiment of the present invention. As shown in fig. 1, in this embodiment, the control method of the wiper includes the steps of:

Step S100, acquiring time information and starting timing when a wiper function of a vehicle is started, and receiving picture information of a windshield acquired by a camera;

step S200, processing the picture information to obtain position information of a wiper, rainfall information outside a vehicle and time information;

step S300, judging whether the current time is in a daytime period according to the time information; if yes, go to step S400;

Step S400, judging whether the rainfall reaches a preset value according to the rainfall information; if not, executing step S500;

step S500, judging whether the wiper reaches a target position within a set duration according to the position information of the wiper; if not, executing step S600;

Step S600, judging whether the wiper motor fails; if not, executing step S700;

and step S700, controlling the wiper to reversely run when the running time of the wiper reaches the set time.

Here, step S300 and step S400 are not sequentially divided, and the camera uses a front camera of the vehicle.

In step S500, if it is determined that the wiper does not reach the target position within the set time period, it may be the case that the camera fails, and the image information acquired by the camera may be inaccurate, so the controller may consider that the wiper does not reach the target position according to the incorrect image, and in fact, the wiper may already reach the target position within the set time period.

In step S600, when it is determined that the wiper does not reach the target position, it is further determined whether the wiper motor fails, so that the wiper does not reach the target position due to the failure of the wiper motor, and if not, the probability of the failure of the camera is high, thereby improving the accuracy of determining whether the camera fails.

According to the embodiment, the camera and the timing mode are combined, and when the camera cannot provide accurate picture information and the position of the wiper cannot be accurately judged, the wiper is controlled to perform reverse movement in a timing mode, so that the normal operation of the wiper cannot be affected.

In this embodiment, the system start timing is the calculated one-way operation duration of the wiper, and the timing is reset to zero and restarted when the wiper starts to perform reverse operation.

In traditional technical scheme, after the user opens the windscreen wiper function, the windscreen wiper begins to carry out round trip operation, and after the windscreen of vehicle was hung the brush clean, the user closed the windscreen wiper function again, in order not to shelter from user's sight, and the windscreen wiper can continue to operate, and when the windscreen wiper operated to the physical position, the windscreen wiper touched the contact switch that resets of fixing in the windscreen below, and the contact switch that resets can transmit back the signal to the controller, and the controller closes the windscreen wiper motor to stop driving windscreen wiper and continue to hang the brush. In this embodiment, the actual position of the wiper is determined according to the picture information of the windshield collected by the camera, and when the user closes the wiper, if the user determines that the wiper does not reach the target position, the controller continuously controls the wiper motor to drive the wiper to operate until the user determines that the wiper reaches the target position, and controls the wiper motor to stop driving the wiper to operate.

Fig. 2 is a schematic flowchart of a control method of a wiper according to another embodiment of the present invention. As shown in fig. 2, in step S300, if not, step S700 is performed; in step S400, if yes, step S700 is executed; in step S500, if yes, the process returns to step S100. That is, if the current time is not in the daytime period or the rainfall reaches the preset value, the wiper is controlled to perform reverse operation when the operation duration of the wiper reaches the set duration. It can be understood that if the current time is in the night time period or when the rainfall is very big, the camera has a high probability of not being able to work normally, and the judgment of the position of the wiper and the control of the motor of the wiper can be influenced, so that the normal operation of the wiper can be directly influenced. Therefore, when the embodiment is in the night time period or the rainfall is large, the wiper motor is directly controlled according to the set time period to drive the wiper to reciprocate, the phenomenon that the normal operation of the wiper is influenced by the fact that the camera cannot work normally is avoided, and the accuracy of the operation of the wiper is improved.

In step S600, if yes, step S800 is executed;

step S800, generating wiper motor fault information to remind a user to repair the wiper motor in time, so that the normal operation of the wiper is prevented from being influenced.

Fig. 3 is a schematic flowchart of a control method of a wiper according to still another embodiment of the present invention. As shown in fig. 3 and see fig. 2. In this embodiment, the following steps are further included before step S500:

step S410, obtaining gear information of a wiper;

Step S420, determining a set duration corresponding to gear information according to the gear information of the wiper when the wiper is in a speed gear;

Step S430, determining the running speed of the wiper motor according to the rainfall information when the wiper is in an automatic gear;

Step S440, calculating a set duration according to the running speed of the wiper motor and the set stroke value. Here, step S420 and step S430 have no precedence relationship.

In this embodiment, the wiper blade has a manual gear and an automatic gear, wherein the manual gear, that is, the speed gear, is divided according to the speed, specifically includes three speed gears of low speed, medium speed and high speed, and a user can select a wiper blade gear of a suitable speed according to his own requirement. Each speed gear corresponds to different set time length, and the set time length corresponding to each speed gear is a fixed value set according to the vehicle type. For example, the set period of the low gear may be set to 6.5s, the set period of the medium gear may be set to 3.5s, and the set period of the high gear may be set to 1.5s. It can be understood that the larger the speed gear is, the faster the running speed of the wiper is, the shorter the corresponding set time period is, the smaller the speed gear is, the slower the running speed of the wiper is, and the longer the corresponding set time period is.

When the wiper is in the automatic gear, the set time period is not a fixed value and is different from the speed gear. The set duration is specifically calculated according to the running speed of the wiper motor and the set travel value. In this embodiment, the operation speed of the wiper motor is determined based on the rainfall information, and the higher the rainfall, the faster the operation speed of the wiper motor, and the shorter the round trip operation time of the wiper, whereas the lower the rainfall, the slower the operation speed of the wiper motor, and the longer the round trip operation time of the wiper. Here, the set stroke value is specifically set according to the vehicle type, and the set stroke value of the wiper motor is different for each vehicle type.

In this embodiment, the operation speed of the wiper motor is calculated according to the following equation:

V＝η*X；

Wherein V represents the running speed of the wiper motor;

η represents a first calibration factor;

x represents a rain value.

In this embodiment, the set time period is calculated according to the following formula:

T＝S/V*β，1＜β＜1.2；

Wherein S represents a set stroke value of the wiper motor;

beta represents a second calibration coefficient;

T represents a set period of time.

In a preferred embodiment, beta is 1.05, which ensures that the wiper blade is in place. In other embodiments, β may also be set according to specific design requirements.

In this embodiment, the control method further includes the steps of:

Step one: receiving picture information of a windshield collected by a camera when a wiper function of a vehicle is closed;

step two: processing the picture information to obtain the position information of the wiper;

Step three: when the position of the wiper is deviated from the original position, the wiper motor is controlled to drive the wiper to move to the original position, and the original position is positioned at the bottom of the windshield of the vehicle, which is equivalent to controlling the wiper motor to drive the wiper to move to the original position, so that the sight of a driver is prevented from being influenced. In this embodiment, the target position of the wiper blade has two, one of which coincides with the original position and the other of which makes a preset angle with the bottom of the windshield, the preset angle being set according to specific design requirements.

In this embodiment, in step S700, the following steps are further included:

step three: generating camera fault information;

Step four: and eliminating the fault information of the camera when the wiper reaches the target position within a set time period. Here, there is no precedence relationship between the third step and the first step.

In this embodiment, after the wiper function of the vehicle is turned on, if the user adjusts the wiper to a speed gear, for example, a low speed gear, and the wiper starts to count time while running, if the count time period reaches 6.5s, the controller determines that the camera has failed according to the picture information collected by the camera that the wiper has reached the target position on the other side, and the wiper motor has not failed to stop, and generates and reports camera failure information, the controller directly controls the wiper motor to reverse, the system starts to count time again, if 6.5s later, the controller does not clear the camera failure information according to the picture information collected by the camera or the wiper has not identified that the wiper has reached the target position on the other side, and if the controller identifies that the wiper has reached the target position on the other side within 6.5s, the controller controls the wiper motor to reverse immediately, and clears the camera failure information.

If a user adjusts the windscreen wiper gear to an automatic gear, the controller can detect a rainfall value X according to picture information acquired by the camera, and the controller can calculate the running speed V of the windscreen wiper motor according to the rainfall value X, and the larger the rainfall value X is, the larger the running speed V of the windscreen wiper motor is. And the controller can also calculate the set duration T required by the single stroke of the wiper according to the running speed V of the wiper motor and the set stroke value S of the wiper motor, and timely control the wiper motor to reverse according to the set duration T when the camera head fails. In order to reduce the operation amount of the control system, the operation speed V and the set time length T of the wiper motor are calculated based on the time points of the beginning operation and the reverse operation of the wiper, a small change value of the wiper value X is not updated in the middle process of the wiper operation, timing is started when the wiper motor begins to operate, and if the timing time length reaches the calculated set time length T, the controller directly controls the wiper motor to reverse according to the picture information acquired by the camera when the wiper is not operated in place and the wiper motor fails, and generates and reports the fault information of the camera. And if the controller detects that the wiper is in place after the set time length T, clearing the fault information of the camera. After the vehicle starts, the camera starts to work, and if camera fault information still exists and no rainfall exists, the controller can forcedly control the wiper to reset according to the camera data, so that the wiper is ensured to stop at an original position, and the sight of a user is prevented from being influenced.

In this embodiment, the wiper blade gear also has a wiper blade mist gear, a wiper blade water spray gear, and a wiper blade INT gap gear, and when the wiper blade is in the mist gear, the control logic of the wiper blade is consistent with the set time and speed of the low gear, and the camera failure determination is also consistent with the low gear, but the wiping is stopped only once when the wiper blade is in the mist gear. When the wiper is positioned in the water spraying gear, the control logic of the wiper is consistent with the set time and speed of the low-speed gear, the fault judgment of the camera is also consistent with the low-speed gear, but the wiper is stopped only by hanging three times when the wiper is positioned in the water spraying gear. When the windscreen wiper is positioned at the INT gap gear, the control logic of the windscreen wiper is consistent with the set time and speed of the low-speed gear, but after each brushing, the user needs to wait for the intermittent time selected by the user and then brush.

Fig. 5 is a schematic connection block diagram of a control system 100 of a wiper according to another embodiment of the present invention. As shown in fig. 5, in this embodiment, the control system 100 for a wiper further includes a camera 20, a wiper motor 30, a wiper 40, and an electronic device 10, where the wiper motor 30 is connected to the wiper 40 for driving the wiper 40 under control. The camera 20 is installed at a position of the vehicle near the windshield for acquiring picture information of the windshield, specifically, the camera 20 is installed in the front windshield and behind the rear view mirror as a front eye of the vehicle, and can detect a view in front of the vehicle in real time for intelligent high beam function of the vehicle, lane line recognition, traffic sign recognition, and the like. Those skilled in the art will appreciate that the camera mounted on the front windshield has a wide visual range, the focal length of the common wide-angle lens is typically 38-24 mm, the viewing angle is 60-84 degrees, the focal length of the ultra-wide-angle lens is 20-13 mm, the viewing angle is 94-118 degrees, and the ultra-wide viewing angle is sufficient to see the entire contour of the wiper 40. In this embodiment, the controller firstly performs data processing on the image collected by the camera 20, and since the windshield is transparent, and the glass frame and the windscreen wiper 40 are both black, the windshield, the windscreen wiper 40 and the whole region of the glass frame can be identified by the gray scale and brightness feature extraction algorithm in machine learning, and then the glass frame module, the windscreen wiper 40 and the windshield can be distinguished by the shape feature identification algorithm. In the embodiment, only the angle values of the target positions on the left side and the right side of the wiper 40 relative to the lower edge of the windshield frame are calibrated, and then the angle ranges of the return area and the reverse area are identified in a software algorithm, so that the timing of the forward and reverse rotation of the wiper motor 30 and the stop of the wiper 40 can be accurately controlled. In addition, considering that the controller may have time delay in processing the picture, the embodiment may also perform a calibration process of a delay time according to an actual operation condition, so as to prevent the wiper 40 from running beyond a boundary.

When the user opens the wiper, the camera 20 transmits the acquired picture information of the windshield to the controller in real time, the controller processes the picture information to obtain the position information and the rain amount information of the wiper 40, and then the controller comprehensively judges the action required to be executed by the wiper 40 according to the position information and the wiper gear information of the wiper 40 and then drives the wiper motor 30 to act. If the rainfall is too large or at night, when the camera 20 cannot shoot a picture when the wiper 40 runs, the controller can ensure the normal reciprocating motion of the wiper 40 through the running time of the wiper 40, and the controller can automatically correct the zero position of the wiper 40 after the rainfall is reduced or stopped. In addition, if the wiper 40 is in an automatic gear, the controller may determine the amount of rain through the pictures collected by the camera 20 and automatically adjust the hanging brush speed, that is, the operation speed of the wiper motor 30 according to the amount of rain. In addition, if the wiper 40 is not in place for more than a set period of time due to the jamming of the wiper motor 30 or various reasons including, but not limited to, a locked-up rotation, the controller may determine that the system is faulty and prompt the user at the dashboard.

This embodiment also provides a vehicle including the control system 100 described above. For the control system 100, a detailed description is omitted here.

In this embodiment, after the controller detects that the wiper 40 is not in place all the time according to the picture acquired by the camera 20, and determines that no locked rotation of the wiper motor 30 occurs according to the current and the temperature of the wiper motor 30, the controller determines that the camera 20 works abnormally, and automatically switches to a time control mode, that is, when the unidirectional operation time of the wiper 40 exceeds a set time length, the controller controls the wiper motor 30 to perform reverse operation, thereby realizing the round trip operation of the wiper 40, ensuring the normal operation of the wiper 40, and ensuring the operation precision of the wiper 40.

By now it should be appreciated by those skilled in the art that while a number of exemplary embodiments of the invention have been shown and described herein in detail, many other variations or modifications of the invention consistent with the principles of the invention may be directly ascertained or inferred from the present disclosure without departing from the spirit and scope of the invention. Accordingly, the scope of the present invention should be understood and deemed to cover all such other variations or modifications.
