Description

Technical Field

[0001] The present disclosure relates to the field of vehicle technology, and in particular to a wiper control method, device, storage medium, electronic device and vehicle. Background Art

[0002] When the wipers of existing vehicles receive a shutdown command, the wiper strips in the wipers are retracted and stopped at the initial position. Correspondingly, the motor connecting rod and the crank in the wipers also return to the initial position. When the motor connecting rod and the crank return to the initial position, the motor connecting rod and the crank are on the same straight line, i.e., collinear. However, in some abnormal working conditions, such as snowy working conditions, the snow on the windshield of the vehicle is scraped to the side of the windshield by the wiper strips. Since there is snow on the side of the windshield, when the wipers receive a shutdown command, the wiper strips are retracted and are hindered by the snow during the downward movement. The wiper strips and the wiper arms are blocked and cannot return to the initial position, while the motor connecting rod and the crank are forced to return to the initial position.

[0003] In response to the above-mentioned snow accumulation situation, the wiper blade is retracted and is hindered by the snow during the downward movement and cannot continue to move downward to the initial position, but the motor connecting rod and the crank are forced to return to the initial position. When the motor connecting rod and the crank are forced back to the initial position, the crank and the motor connecting rod are in line. Since the wiper blade and the wiper arm are blocked, the wiper arm is subjected to the reverse thrust of the wiper blade. This thrust will continue to act on the crank through the motor connecting rod, causing the crank to deform. Summary of the invention

[0040] In order to more clearly understand the above-mentioned objectives, features and advantages of the present disclosure, the scheme of the present disclosure will be further described below. It should be noted that the embodiments of the present disclosure and the features in the embodiments can be combined with each other without conflict.

[0041] In the following description, many specific details are set forth to facilitate a full understanding of the present disclosure, but the present disclosure may also be implemented in other ways different from those described herein; it is obvious that the embodiments in the specification are only part of the embodiments of the present disclosure, rather than all of the embodiments.

[0042] The wiper control method provided by the disclosed embodiment obtains the running speed of the wiper strip of the wiper when it enters the termination area during the downward movement, and determines whether the movement of the wiper strip is abnormal based on the running speed of the termination area; when it is determined that the movement of the wiper strip is abnormal, the motor driving the movement of the wiper strip is controlled to stop rotating when the crank and the motor connecting rod of the wiper are not collinear, which can avoid the motor connecting rod and the crank being returned to the initial position, thereby avoiding the crank and the motor connecting rod from being collinear, and solves the problem that the wiper strip and the wiper arm are blocked during the retraction process, and the motor connecting rod and the crank are forced to return to the initial position, the crank and the motor connecting rod are collinear, and the wiper arm is subjected to the reverse thrust of the wiper strip, and the thrust acts on the crank through the motor connecting rod, causing the crank to deform.

[0043] The following is an illustrative description of the vehicle wiper control method, device, storage medium, electronic device and vehicle provided in the embodiments of the present disclosure in conjunction with the accompanying drawings.

[0044] Figure 1 The present invention provides a flow chart of a wiper control method according to an embodiment of the present invention. The present method is applicable to the application scenario of controlling the vehicle wiper. The present method can be executed by the wiper control device according to an embodiment of the present invention, and the wiper control device can be implemented in software and / or hardware. Figure 1 As shown, the wiper control method includes the following steps:

[0045] S101. In response to a wiper closing instruction, obtaining a running speed of a wiper strip of the wiper entering a termination area during a downward movement.

[0046] Specifically, when the vehicle user does not need to use the wiper, the wiper can be turned off, for example, by triggering a button for turning off the wiper, and sending a command to the vehicle controller to stop the wiper through the button. After receiving the command, the vehicle controller controls the wiper strip to move downward and retract. When the wiper strip enters the termination area during the downward movement and retraction process, the running speed of the wiper strip is detected. Exemplarily, the running speed of the wiper strip can be obtained by an angular velocity sensor.

[0047] The end area may be an area adjacent to the side of the windshield. Figure 2 The following is a simplified structural diagram of a windshield provided in an embodiment of the present disclosure. Figure 2 As shown, the termination area is shown by reference numeral 21. In conjunction with the following, when encountering snowfall conditions, when the wiper strip enters the termination area 21 during the retraction process, the wiper strip has abnormal movement. Specifically, the snow on the windshield of the vehicle is scraped to the side of the windshield by the wiper strip, resulting in snow accumulation in the termination area 21. When the wiper strip enters the termination area 21 during the retraction process, the wiper strip is blocked by the snow, resulting in abnormal movement of the wiper strip.

[0048] The wiper includes a wiper strip, a wiper arm, a motor connecting rod, a crank and a motor. The detailed structure and working principle of the wiper are common knowledge to those skilled in the art and will not be elaborated here.

[0049] S201, determining that the wiper strip movement is abnormal based on the running speed in the termination area being less than the speed reference value, and controlling the motor driving the wiper strip to stop rotating when the crank of the wiper and the motor connecting rod are not in line.

[0050] Specifically, based on the running speed of the wiper strip entering the termination area acquired in S101, when the running speed is less than the speed reference value, it can be determined that the wiper strip is moving abnormally.

[0051] When it is determined that the wiper strip is moving abnormally, when the wiper crank and the motor connecting rod have not returned to the initial position, that is, when the wiper crank and the motor connecting rod are not in the same straight line, the motor driving the wiper strip is controlled to stop rotating. In this way, the problem that the wiper strip is blocked during the retraction movement and cannot continue to move downward to the initial position, while the motor connecting rod and the crank are forced to return to the initial position can be avoided. This solves the problem in the background technology that the wiper strip and the wiper arm are blocked, but the motor connecting rod and the crank are forced to return to the initial position, and the wiper arm is subjected to the reverse thrust of the wiper strip, and the thrust will continue to act on the crank through the motor connecting rod, thereby causing the crank to deform.

[0052] For example, Figure 3 A schematic diagram of a motor connecting rod and a crank returning to an initial position provided in an embodiment of the present disclosure. Figure 3 As shown, when the motor connecting rod 31 and the crank 32 return to the initial position, the motor connecting rod 31 and the crank 32 are collinear. It should be noted that when the motor connecting rod 31 and the crank 32 are not collinear, that is, the motor connecting rod 31 and the crank 32 have not returned to the initial position, if the wiper strip and the wiper arm are blocked at this time, the wiper arm is subjected to the reverse thrust of the wiper strip, and the thrust acts on the crank 32 through the motor connecting rod 31, which will not cause the crank 32 to deform.

[0053] The wiper control method provided by the embodiment of the present disclosure includes: in response to a wiper closing instruction, obtaining the running speed of the wiper strip of the wiper entering a termination area during downward movement; determining that the wiper strip movement is abnormal based on the running speed in the termination area being less than a speed reference value, and controlling the motor that drives the wiper strip to move to stop rotating when the crank of the wiper is not colinear with the motor connecting rod. Therefore, by obtaining the running speed of the wiper strip when it enters the termination area during the downward movement, it is determined whether the movement of the wiper strip is abnormal based on the running speed of the termination area; when it is determined that the movement of the wiper strip is abnormal, the motor that drives the movement of the wiper strip is controlled to stop rotating when the crank and the motor connecting rod of the wiper are not collinear, which can avoid the motor connecting rod and the crank being returned to the initial position, thereby avoiding the crank and the motor connecting rod from being collinear, and solving the problem that the wiper strip and the wiper arm are blocked during the retraction process, and the motor connecting rod and the crank are forced to return to the initial position, the crank and the motor connecting rod are collinear, and the wiper arm is subjected to the reverse thrust of the wiper strip, and this thrust acts on the crank through the motor connecting rod, causing the crank to deform.

[0054] In some embodiments, determining that the wiper strip movement is abnormal based on the running speed of the termination area being less than a speed reference value includes:

[0055] Obtain the running speed of the wiper strip corresponding to multiple consecutive moving positions in the termination area;

[0056] When the running speeds corresponding to a plurality of consecutive moving positions are all less than the speed reference value at the corresponding moving positions, it is determined that the wiper strip moves abnormally.

[0057] Specifically, the corresponding relationship between the position and speed of the wiper strip during the downward movement can be calibrated in advance, and then the speed reference value corresponding to the movement position of the wiper strip can be determined according to the corresponding relationship. The speed reference value is the running speed corresponding to the movement position of the wiper strip when the wiper strip does not encounter abnormal working conditions. For example, Figure 4 A schematic diagram of a speed reference value corresponding to a wiper strip motion position provided by an embodiment of the present disclosure. Figure 4 As shown, the X-axis represents the movement position of the wiper strip, the Y-axis represents the running speed of the wiper strip, the upper side of the X-axis represents the upward movement process of the wiper strip, and the lower side of the X-axis represents the downward movement process of the wiper strip.

[0058] The operating speed of the wiper strip is obtained to be less than the corresponding speed reference value at multiple consecutive positions. At this time, it can be determined that the wiper strip is blocked by the snow when encountering the snowy working condition, resulting in a decrease in the operating speed of the wiper strip, that is, the wiper strip moves abnormally.

[0059] In some embodiments, when the operating speed of the wiper strip at a position is less than the corresponding speed reference value, the wiper strip movement abnormality can also be determined. In other embodiments, the wiper strip movement abnormality can also be determined by using the average speed of the wiper strip in a section of the area being less than the average speed reference value of the wiper strip in the section of the area. For example, the normal average operating speed of the wiper strip when entering the termination area during the downward movement is about 0.4° / 3ms. If the speed of the wiper strip is lower than the average speed reference value, such as 0.3° / 3ms, the wiper strip movement abnormality can be determined.

[0060] In some embodiments, controlling a motor driving a wiper strip to stop rotating when a crank of the wiper and a motor connecting rod are not in line with each other includes:

[0061] generating a first motor stop instruction;

[0062] The wiper motor is controlled to rotate based on the first motor stop command until the wiper strip is in a blocked state and stops rotating.

[0063] Specifically, in combination with the above, when it is determined that the wiper strip moves abnormally, a first motor stop command may be generated. After the first motor stop command is generated, the motor of the wiper does not stop rotating immediately, but stops rotating when the wiper strip is in a blocked state.

[0064] For example, when the wiper strip encounters snow during the downward movement, the wiper strip moves abnormally. At this time, the wiper strip slows down, but the wiper strip is not completely blocked and can continue to move downward until the wiper strip cannot move further, that is, when the wiper strip's operating speed is zero, the motor controlling the wiper stops rotating. After the motor stops rotating, the crank of the wiper and the motor connecting rod will not return to the initial position, and the crank of the wiper and the motor connecting rod are not in the same straight line. At this time, the wiper strip and the wiper arm are blocked, and the wiper arm is subjected to the reverse thrust of the wiper strip. The thrust acts on the crank through the connecting rod motor connecting rod, which will not cause the problem of crank deformation.

[0065] Based on this, a first motor stop instruction is generated, and according to the first motor stop instruction, the motor of the wiper is controlled to rotate until the wiper strip is in a blocked state and stops rotating.

[0066] In some embodiments, controlling a motor for driving a wiper strip to stop rotating when a crank of the wiper and a motor connecting rod are not in line with each other includes:

[0067] generating a second motor stop command;

[0068] The wiper motor is controlled to immediately stop rotating based on the second motor stop command.

[0069] Specifically, in combination with the above, when it is determined that the wiper strip moves abnormally, a second motor stop instruction may be generated. After the second motor stop instruction is generated, the motor controlling the wiper immediately stops rotating.

[0070] For example, when the wiper strip encounters snow during downward movement, the wiper strip moves abnormally, and the motor controlling the wiper stops rotating immediately. After the motor stops rotating, the wiper strip will not continue to move downward, so the force blocking the wiper strip and the wiper arm is small. In addition, the crank of the wiper and the motor connecting rod will not return to the initial position, and the crank of the wiper and the motor connecting rod are not in the same straight line. At this time, the wiper strip and the wiper arm are blocked and the blocking force is small, and the wiper arm is subjected to a small reverse thrust from the wiper strip. This thrust acts on the crank through the connecting rod motor connecting rod and will not cause the crank deformation problem.

[0071] Based on this, a second motor stop command is generated, and the motor of the wiper is controlled to stop rotating immediately according to the second motor stop command.

[0072] In some embodiments, after determining that the wiper strip moves abnormally, the wiper control method further includes:

[0073] Controlling the wiper strip to perform upward and downward reciprocating motion, and the number of upward motions of the wiper strip is less than or equal to a number threshold;

[0074] Wherein, during each downward movement of the wiper strip in the reciprocating motion, it is determined that the wiper strip has abnormal movement, and the upward movement of the wiper strip is triggered.

[0075] Specifically, when it is determined that the wiper strip moves abnormally, the wiper strip can be controlled to perform upward and downward reciprocating motion, and the snow in the termination area can be removed by utilizing the adhesion between the wiper strip and the snow through the upward and downward reciprocating motion of the wiper strip.

[0076] For example, the number threshold may be set to 5. During the fifth downward movement of the wiper strip, if it is determined that the wiper strip is moving abnormally, it indicates that the wiper strip is still obstructed by the accumulated snow, and the obstruction of the wiper strip cannot be resolved by controlling the wiper strip to move upward and downward reciprocatingly, and the upward movement of the wiper strip may be stopped at this time.

[0077] In some embodiments, before obtaining the running speed of the wiper strip of the wiper entering the termination area during the downward movement, the wiper control method further includes:

[0078] Get weather information in the area where the vehicle is located;

[0079] Based on weather information, determine whether the current weather is snowing;

[0080] It is determined that the current weather is snowing, and the running speed of the wiper blade of the wiper entering the termination area in the downward movement is obtained.

[0081] Specifically, after receiving the wiper-off command, the weather conditions of the vehicle's current environment can be obtained. When it is obtained that it is snowing, it can be determined that there may be snow accumulation during the retraction of the wiper strip. For example, the wiper strip is obstructed by the accumulated snow, causing abnormality during the retraction process. At this time, the running speed of the wiper strip entering the termination area during the downward movement is obtained.

[0082] When it is obtained that the previous weather is not snowing, there is no need to consider the influence of snow accumulation on the retraction of the wiper strip. The motor of the wiper can be controlled to rotate to the initial position, that is, the existing conventional control method can be executed.
