[0002] Windshield wipers have become standard equipment for motor vehicles. Windshield wipers are devices installed on the windshield of cars to remove rain, snow, dust and other debris to keep the driver's vision clear. It drives the wiper blades to move on the windshield through the wiper arm, thereby removing liquids and dirt that affect the line of sight and ensuring driving safety. As an important part of the wiper, the wiper blade is mainly made of soft materials such as rubber. Under the force generated by the spring in the wiper arm, the wiper blade is firmly pressed against the windshield regardless of whether the vehicle is started or turned off.

[0003] In the prior art, the wiper can usually only swing left and right by the motor. When the vehicle is not used for a long time in the northern winter, if the driver does not lift the wiper arm away from the glass, the wiper blade will freeze on the glass due to low temperature in high humidity or rainy and snowy days, making it impossible to use normally. In the summer, if the wiper is not lifted after parking in hot weather, the temperature of 60 to 70 degrees on the glass can easily damage the wiper blade prematurely. Some experienced drivers lift the wiper arm in the above weather to prevent the wiper from being damaged. Summary of the invention

[0043] The following describes the embodiments of the present invention by specific examples, and those skilled in the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present invention. It should be noted that the following embodiments and features in the embodiments can be combined with each other without conflict.

[0044] It should be noted that the illustrations provided in the following embodiments are only used to schematically illustrate the basic concept of the present invention, and thus the illustrations only show components related to the present invention rather than being drawn according to the number, shape and size of components in actual implementation. In actual implementation, the type, quantity and proportion of each component may be changed arbitrarily, and the component layout may also be more complicated.

[0045] Winter and summer may have different effects on aging and wear of wiper blades:

[0046] In winter:

[0047] Wipers may encounter freezing and icing. When wipers come into contact with snow and ice, the wiper blades 30 and rubber components may become hard and brittle, resulting in poor wiping effect or noise during wiping. Frozen wipers may also suffer damage, such as cracking of the wiper blades 30 or falling off of the wiper blades 30.

[0048] In cold regions, salt or other chemicals are often used to remove ice on the road. These chemicals may splash onto the windshield and the wiper blades. When the wiper blades are attached to the glass, these substances may remain between the wiper blades and the glass for a long time. These chemicals may corrode or embrittle the material of the wiper blades, resulting in reduced wiping effect, and may cause premature aging of the wiper blades 30 and more frequent replacement requirements.

[0049] In summer:

[0050] In summer, the sunlight is strong and the material of the wiper may soften. If it is pressed against the glass for a long time, the wiper blade 30 may be deformed, thereby reducing the wiping effect.

[0051] At the same time, the hot and dry summer, coupled with dust and particles on the road, may form a thin layer of dust on the wiper, which may remain between the wiper and the glass for a long time when the wiper is attached to the glass. These dust and particles may wear the surface of the wiper blade 30, resulting in reduced wiping effect and increased wear and aging speed of the wiper blade 30.

[0052] like Figure 1 As shown, the present invention provides a wiper, comprising a first driving unit 10 and a second driving unit 20, wherein the first driving unit 10 is used to drive the wiper blade 30 to scrape along the glass surface of the car; the second driving unit 20 is used to drive the wiper blade 30 to fit into or away from the glass surface of the car.

[0053] A windshield wiper usually consists of the following main parts:

[0054] Wiper blade 30: Wiper blade 30 is a key part of the wiper, usually made of rubber or silicone. It is located on the wiper arm and attached to the windshield surface to scrape off rain and other dirt.

[0055] Wiper arm: The wiper arm is a metal arm-like structure connecting the wiper blade 30 and the upper part of the car. Its length and shape vary according to the car model and design, and it can be moved to cover most of the surface of the windshield. The wiper arm includes a first arm 40 that can swing left and right and a second arm 50 that can swing forward and backward. The first arm 40 is connected to the first drive unit 10, and the first arm 40 is connected to the second arm 50 through the second drive unit 20. The wiper blade 30 is arranged on the second arm 50. The first arm 40 and the second arm 50 are hingedly arranged by a hinge shaft, and the axis core direction of the hinge shaft is parallel to the swing direction of the first drive unit 10. The second drive unit 20 can be a motor coaxially arranged with the hinge shaft to drive the hinge shaft to rotate, or it can be a pneumatic rod or hydraulic rod structure with both ends hinged to the first arm 40 and the second arm 50 respectively. The existing common wiper itself has a first arm 40 and a second arm 50, and both are also hingedly arranged. Usually, it is necessary to manually fold the second arm 50 and rotate it around the hinge axis to achieve the wiper blade to fit / move away from the car glass surface. In the present application, a motor or a hydraulic rod or a pneumatic rod is added to replace the original manual folding so that the lifting and fitting of the wiper blade can be directly controlled by the vehicle electrical system.

[0056] Wiper motor: The vehicle is generally equipped with a wiper motor, namely the first drive unit 10 and the second drive unit 20 in this application, for driving the movement of the wiper arm. The first drive unit 10 and the second drive unit 20 are powered by the vehicle electrical system and controlled by a switch or automatic sensor.

[0057] Control switch: The driver can use the switch located on the steering wheel or dashboard of the car to control the operation mode of the wiper, including adjusting the wiper speed and enabling / disabling the spray function. The control switch in this application also includes a lift / close switch that controls the action of the second drive unit 20.

[0058] Embodiment 1, as Figure 2 As shown, the present invention also provides a wiper control method, which is used for the above-mentioned wiper, comprising the following steps:

[0059] S1. Obtain wiper status, vehicle speed and ambient temperature.

[0060] The wiper status includes the wiper working status and the wiper height status. The wiper working status refers to whether the wiper is in a state of wiping left and right, and the wiper height status refers to whether the wiper is lifted away from the glass or in contact with the glass.

[0061] When obtaining the wiper height status, vehicle speed, wiper working status and ambient temperature, they need to be obtained in sequence. If one condition is not met, no further acquisition will be made to save computing power, such as Figure 3 As shown, the acquisition methods are as follows:

[0062] S11. Obtain wiper height status.

[0063] The wiper height status information is obtained on the vehicle side, that is, the state of the wiper being lifted away from the glass or in contact with the glass. The information required to be obtained in the two working states is different. For example, when the wiper is lifted away from the glass, only the vehicle speed needs to be obtained. When the wiper is in contact with the glass, the wiper working status and the ambient temperature need to be obtained in turn.

[0064] S12: Obtain vehicle speed.

[0065] When the wiper height is raised, as long as the vehicle speed is greater than 0, the wiper will be driven directly to fit the vehicle glass to avoid safety hazards caused by the owner forgetting to put down the wiper. When the wiper height is fitted, the vehicle speed needs to be obtained to determine whether the vehicle is stationary. The vehicle speed information can also be the engine start information or vehicle power-on information. The state of vehicle speed equal to 0 corresponds to the engine shutdown or vehicle power-off state, and the state of vehicle speed greater than 0 corresponds to the engine start or vehicle power-on state.

[0066] S13. When the wiper height state is in close contact and the vehicle speed is equal to 0, the wiper working state is obtained; otherwise, the wiper working state is not obtained.

[0067] When the vehicle speed is 0, it is judged that the vehicle is stationary. When the wiper height state is close, it is necessary to obtain the wiper working state. At this time, the ambient temperature is judged to reduce the computing power requirements. At the same time, when the vehicle speed is 0, lifting the wiper will not affect the driver's driving, so as to avoid safety hazards caused by lifting the wiper during driving.

[0068] S14. When the wiper is in a stationary state, the ambient temperature is obtained; otherwise, the ambient temperature is not obtained.

[0069] The wipers on some vehicles will also swing left and right when they are stationary. If you lift the wipers when they are swinging left and right, they may collide with the vehicle or other obstacles and cause damage. Therefore, you should lift the wipers only when the wipers stop swinging. The vehicle temperature sensor is used to obtain the external ambient temperature.

[0070] S2. According to the wiper state, vehicle speed and ambient temperature, the second driving unit 20 drives the wiper blade 30 to approach or move away from the vehicle glass surface.

[0071] In the above steps, when the wiper height state is in contact and the vehicle speed is 0 and the wiper working state is in shutdown state and the ambient temperature exceeds the threshold value T', the wiper blade 30 is driven away from the glass surface of the vehicle by the second driving unit 20; when the wiper height state is in lift and the vehicle speed is greater than 0, the wiper blade 30 is driven to contact the glass surface of the vehicle by the second driving unit 20.

[0072] The threshold value T' is 0-38℃. When the ambient temperature exceeds the threshold value T', it means that the ambient temperature is lower than 0 degrees and greater than 38 degrees. When the temperature is less than 0, it is the frosting temperature. At this time, the wipers need to be lifted to prevent the wipers from freezing and fixing on the windshield. The temperature threshold can also be adaptively adjusted according to the local climate, or set by the owner.

[0073] When lifting the wiper, the first drive unit 10 is used to swing the wiper to a high middle state, and then the second drive unit 20 is used to swing the wiper forward to separate the wiper from the windshield. When attaching the wiper, the operation is performed in the opposite direction, that is, the second drive unit 20 is used to swing the wiper backward to attach the wiper to the windshield, and then the first drive unit 10 is used to swing the wiper to the initial state.

[0074] like Figure 5 As shown, it is a specific flow chart of the present invention, when the wiper height state is in contact, wherein:

[0075] BCM (body control unit) obtains the current vehicle speed;

[0076] Determine the vehicle speed, if the vehicle speed is equal to 0, obtain the current wiper working status;

[0077] The current working state of the wiper is judged. If the wiper is in a non-working state (i.e., stationary state), the current ambient temperature T is obtained;

[0078] Determine whether the current ambient temperature T is less than 0 degrees or greater than 38 degrees. If so, the BCM sends a signal to the wiper arm control motor (i.e., the second drive unit 20 in this application) to lift the wiper arm;

[0079] Continue to obtain the vehicle speed. When the vehicle speed is greater than 0, the BCM sends a signal to the wiper arm control motor, and the wiper arm returns to its initial state, that is, the wiper is in contact with the glass.

[0080] Embodiment 2, as Figure 4 As shown, the present invention also provides a wiper control method for the above-mentioned wiper, comprising the following steps:

[0081] A1. Obtain wiper status, vehicle speed and wiper control instructions.

[0082] The wiper status includes the wiper working status and the wiper height status.

[0083] The wiper control command refers to the switch set in the car to control the lift / apply of the wipers. It can be a physical switch or an option in the central control screen. In this application, an option of actively controlling the lift / apply of the wipers is set to facilitate the driver's independent control and improve the diversity of control options.

[0084] When obtaining the wiper status, vehicle speed and ambient temperature, they need to be obtained in sequence. If one condition is not met, the acquisition will not continue to save computing power. The sequence is: wiper height status-vehicle speed-wiper working status-wiper control command.

[0085] A2. According to the wiper state, vehicle speed and wiper control instruction, the wiper blade 30 is driven to approach or move away from the vehicle glass surface through the second driving unit 20.

[0086] In the above scheme, when the wiper height state is in contact and when the vehicle speed is equal to 0 and the wiper working state is stationary and the wiper control instruction is to lift, the wiper blade 30 is driven away from the car glass surface by the second driving unit 20; when the wiper height state is in contact and when the vehicle speed is greater than 0 or the wiper control instruction is in contact, the wiper blade 30 is driven close to the car glass surface by the second driving unit 20.

[0087] In the above scheme, it is necessary to judge the wiper height state, vehicle speed, and wiper working state before obtaining the wiper control command, so as to avoid damage to the wiper caused by manually lifting the wiper when the wiper height state, vehicle speed, and wiper working state do not meet the lifting conditions. The wiper control command in this embodiment replaces the ambient temperature in the previous embodiment for control, so as to avoid the situation where the wiper needs to be lifted under special circumstances but the temperature has not reached. For example, when the owner needs to replace the wiper, he can lift the wiper by pressing the button in the car without manually lifting the wiper.

[0088] The present invention also provides a wiper control system, comprising:

[0089] An information acquisition module is used to obtain the wiper status, vehicle speed and ambient temperature;

[0090] The control module is used to drive the wiper blade 30 to approach or move away from the glass surface of the vehicle through the second driving unit 20 according to the wiper state, vehicle speed and ambient temperature.

[0091] The corresponding wiper status of the vehicle in various working conditions is as follows:

[0092] When the vehicle is moving, the wiper blade 30 lifting function is in a closed state;

[0093] When the vehicle is stationary and the engine is turned off, and the outside temperature is below 0°C or above 38°C, the wiper arm automatic lifting function is turned on. The BCM obtains the outside temperature through the outside temperature sensor, the wiper motor status, and the vehicle speed to determine whether the wiper arm needs to be lifted:

[0094] When the ambient temperature is below 0℃ and the vehicle is turned off, it is determined that the windshield may be frosted for a long time, causing the wiper blade 30 to freeze on the glass, reaching the wiper arm lifting condition. At this time, the BCM (body control module) controls the wiper arm lifting motor to control the wiper arm to lift. When the vehicle speed is greater than 0, the BCM controls the wiper arm lifting motor to return to the initial position of the wiper arm, that is, the wiper blade 30 is controlled to fit the car glass surface.

[0095] When the ambient temperature is lower than 38°C and the vehicle is turned off, it is determined that the windshield temperature may be too high for a long time, causing damage to the wiper blade 30, and reaching the wiper arm lifting condition. At this time, the BCM controls the wiper arm lifting motor to control the wiper arm to lift. When the vehicle speed is greater than 0, the BCM controls the wiper arm lifting motor to restore the wiper arm to its initial position.

[0096] When the wiper arm is in defrosting or wiping action, the lifting function of the wiper blade 30 is in a closed state and cannot be opened.

[0097] When the wiper position is not in the initial position, the automatic lift function is turned off.

[0098] When the ambient temperature is between 0℃ and 38℃, the automatic wiper lifting function is turned off. The wiper arm can be raised and lowered with one click through the multimedia large-screen soft switch.

[0099] The present invention also provides a vehicle, comprising the wiper control system and the wiper.

[0100] In summary, the present invention proposes a wiper, a wiper control method, a wiper control system and a vehicle. In the above scheme, a second drive unit 20 is added to drive the wiper to fit or move away from the car glass surface, and the wiper is controlled to lift or fit the car glass surface by judging the wiper state, vehicle speed and ambient temperature, so as to avoid the wiper from contacting the windshield for a long time in a high or low temperature environment, thereby causing damage or aging of the rubber on the wiper. By adding a wiper auxiliary motor and a connecting rod structure, an innovative automatic lifting function of the wiper arm is proposed to actively intervene in the wiper state in special weather. This solves the problem that in wet and rainy weather in winter, the wiper blade 30 is frozen on the front windshield when the vehicle is parked outdoors, and the wiper blade 30 contacts the high-temperature glass for a long time outdoors in summer, resulting in premature failure of the wiper blade 30.
