[0002] Current automotive electronic wipers can only achieve high-speed, low-speed, intermittent and other matching wiping frequencies based on the vehicle's high-speed, low-speed, intermittent and other lever commands. For example, the electronic wiper receives user gear information such as high gear and low gear from the LIN communication in the car, and drives the electronic wiper to achieve wiping frequencies of 60 times / minute, 40 times / minute, or even lower - intermittent wiping.

[0003] As wiper functions are expanded, such as using ultra-high-speed wipers in heavy rain mode or wiping in the camera area, users cannot switch from the regular wiper position to the extended wiper position because the positions are not defined on the original wiper stalk.

[0004] If it is necessary to expand the camera area wiping function and ultra-high-speed wiping function on the car wiper, the car's body controller or lever needs to be modified, resulting in a large car modification project and the inability to realize the functional expansion of the electronic wiper system on a large scale.

[0017] In the above solution, the exit information is instruction information generated by the body controller when it receives a third toggle signal sent by the toggle lever; the third toggle signal is a toggle signal for switching from a high gear to a low gear.

[0018] In the above scheme, the windshield sight area is wiped or stopped according to conventional parameters, including:

[0019] If it is determined that the third toggle signal in the exit information is to switch from a high gear to a low gear, the sight area is scraped according to the low gear parameter.

[0041] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0042] Example 1:

[0043] See also Figure 1 A wiper system control method according to this embodiment operates in an electronic wiper system of a vehicle. The method is used to control the electronic wiper system to wipe the windshield. The shift lever of the electronic wiper system is a terminal device for controlling the wiper gear position of the electronic wiper system. The wiper gear positions include: stop gear, low gear, automatic gear, and high gear.

[0044] Methods include:

[0045] S103: receiving instruction information sent by the vehicle body controller; wherein the vehicle body controller is a vehicle control device connected to the lever and configured to generate instruction information according to the movement of the lever;

[0046] S104: If it is determined that the instruction information is video wiping information, wiping the camera area on the windshield according to video wiping parameters; wherein the video wiping parameters include a video wiping range and a video wiping speed; the video wiping range is the wiping range of the electronic wiper system on the windshield, and the video wiping speed is the wiping speed of the electronic wiper system on the windshield; the video area is the area on the windshield corresponding to the camera;

[0047] S105: If it is determined that the instruction information is ultra-high-speed wiping information, the key area on the windshield is wiped according to the ultra-high-speed wiping parameters; wherein the ultra-high-speed wiping parameters include the ultra-high-speed wiping range and the ultra-high-speed wiping speed; the ultra-high-speed wiping range is the wiping range of the electronic wiper system on the windshield, and the ultra-high-speed wiping speed is the wiping speed of the electronic wiper system on the windshield; the key area is the area on the windshield corresponding to the driver.

[0048] In this example, by scraping the camera area on the windshield according to the camera scraping information sent by the lever, the technical effect of targeted scraping of the camera area is achieved, ensuring the transparency of the camera area and further ensuring the clarity of the external environment captured by the camera.

[0049] By wiping key areas on the windshield according to the ultra-high-speed wiping information sent by the lever, targeted high-speed wiping of key areas can be achieved in heavy rain weather, ensuring that the driver has a sufficiently clear view of the external environment, thereby ensuring the safety of car driving.

[0050] The present application is compatible with the existing electronic wiper system's levers and gears. It only requires updating the wiper software in the electronic wiper system, that is, enabling the electronic wiper system to recognize the command sequence of the LIN bus control signal based on the lever operation, thereby realizing extended wiping functions such as ultra-high frequency wiping or camera area wiping. There is no need to add new lever gears or redefine the body LIN bus control signal, avoiding the need to modify the car's body controller or lever due to the expansion of the electronic wiper system's functions, resulting in excessively large car modification projects and the inability to realize the functional expansion of the electronic wiper system on a large scale.

[0051] Optionally, the shift lever is connected to the electronic wiper system through the vehicle body controller, and the shift lever sends a shift signal to the vehicle body controller by shifting, and the vehicle body controller forms a LIN bus control signal according to the shift signal.

[0052] For example, the camera wiping range of the camera area of ​​the wiper rod of the electronic wiper system is 85°-100°, and the camera wiping speed is 60 times / minute.

[0053] The ultra-high frequency scraping range of key areas is 30°-70°, and the ultra-high frequency scraping speed is 70 times / minute.

[0054] It should be noted that the body controller is a crucial component in automotive engineering. As an electronic control unit (ECU), it controls the vehicle's electrical systems. It integrates multiple control functions into one electronic device. It receives input from sensors or other devices and converts this information into signals that can be received by a microprocessor. By storing, calculating, analyzing, and processing this information, the body controller can perform a range of control operations, such as power management, lighting control, wiper system control, central door locking and remote control, and vehicle body and engine anti-theft control. In this embodiment, the body controller controls the operation of the wiper motor, enabling low-speed, high-speed, and intermittent front wiper operation, as well as windshield spraying. Furthermore, it can automatically detect rainfall based on signals from the optical rain sensor and adjust the wiper operating mode.

[0055] In this embodiment, the stop gear is used to control the electronic wiper system to wipe the windshield.

[0056] The low gear is used to control the electronic wiper system to wipe the visual area according to the low gear parameter.

[0057] The automatic gear is used to control the electronic wiper system to intermittently wipe the viewing area according to the low-gear parameters or the high-gear parameters; intermittent wiping means that there is a specified time interval between each wiping action of the electronic wiper system, for example: the electronic wiper system waits for a specified time of 2 seconds each time it wipes, and then wipes again for the next time.

[0058] The high gear is used to control the electronic wiper system to wipe the sight area according to high-end parameters.

[0059] Example 2:

[0060] This embodiment is a specific application scenario of the above-mentioned embodiment 1. Through this embodiment, the method provided by the present invention can be explained more clearly and specifically.

[0061] Figure 2 The windshield, the camera area, the key area and the sight area in the wiper system control method are schematically shown, wherein 21 represents the windshield, 22 represents the camera area, 23 represents the key area and 24 represents the sight area.

[0062] Figure 3This diagram schematically illustrates the wiper and wiping positions of the wiper lever used in the wiper system control method. A represents a single wipe, B represents a stop position, C represents a spray and wipe position, D represents a low speed position, E represents a high speed position, and F represents a spray button. The wipe position automatically resets after one wipe, meaning it automatically stops after one wipe.

[0063] Figure 4 This is a flow chart of a specific method of a wiper system control method provided by one embodiment of the present invention. The wiper system control method is characterized in that it is operated in a vehicle's electronic wiper system and is used to control the electronic wiper system to wipe the windshield. The shift lever is a terminal device for controlling the wiper gear position of the electronic wiper system; the wiper gear position includes: stop gear, low gear, automatic gear, and high gear;

[0064] The method specifically includes steps S401 to S406.

[0065] S401: receiving a first wiping range and a first wiping speed sent by a central control screen of a car, and using the first wiping range as a camera wiping range of an electronic wiper system, and using the first wiping speed as a camera wiping speed of the electronic wiper system;

[0066] S402: Receive a second wiping range and a second wiping speed sent by the car's central control screen, use the second wiping range as the ultra-high-speed wiping range of the electronic wiper system, and use the second wiping speed as the ultra-high-speed wiping speed of the electronic wiper system.

[0067] In this example, the car's central control screen is an interactive device used to output the scraping range and scraping speed to the body controller. Therefore, the driver can adjust the camera scraping range, camera scraping speed, ultra-high-speed scraping range and ultra-high-speed scraping speed through the car's central control screen to meet different user needs.

[0068] S403: receiving instruction information sent by the vehicle body controller; wherein the vehicle body controller is a vehicle control device connected to the shift lever and used to generate instruction information according to the shift lever.

[0069] It should be noted that the body controller is a crucial component in automotive engineering. As an electronic control unit (ECU), it controls the vehicle's electrical systems. It integrates multiple control functions into one electronic device. It receives input from sensors or other devices and converts this information into signals that can be received by a microprocessor. By storing, calculating, analyzing, and processing this information, the body controller can perform a range of control operations, such as power management, lighting control, wiper system control, central door locking and remote control, and vehicle body and engine anti-theft control. In this embodiment, the body controller controls the operation of the wiper motor, enabling low-speed, high-speed, and intermittent front wiper operation, as well as windshield spraying. Furthermore, it can automatically detect rainfall based on signals from the optical rain sensor and adjust the wiper operating mode.

[0070] S404: If it is determined that the instruction information is camera wiping information, the camera area on the windshield is wiped according to the camera wiping parameters; wherein the camera wiping parameters include the camera wiping range and the camera wiping speed; the camera wiping range is the wiping range of the electronic wiper system on the windshield, and the camera wiping speed is the wiping speed of the electronic wiper system on the windshield; the camera area is the area on the windshield corresponding to the camera.

[0071] In this step, the camera area on the windshield is scraped and wiped according to the camera scraping information sent by the lever, thereby achieving the technical effect of targeted scraping of the camera area, ensuring the transparency of the camera area, and further ensuring the clarity of the external environment captured by the camera.

[0072] For example, the camera wiping range of the camera area of ​​the wiper rod of the electronic wiper system is 85°-100°, and the camera wiping speed is 60 times / minute.

[0073] In a preferred embodiment, the camera scraping information is indication information generated by the vehicle body controller receiving M first toggle signals sent by the toggle lever within a preset first time, where M is a natural number greater than 1;

[0074] The first shifting signal is a shifting signal for the shift lever to shift from a low gear to a high gear.

[0075] In this example, the length of the first time is set as needed, for example, 3 seconds; and the number M of the first dialing signals to be sent is set as needed, for example, 3 times;

[0076] Therefore, when the vehicle body controller receives three consecutive first-touch signals within three seconds, it sends an instruction to trigger the electronic wiper system to perform targeted wiping of the camera area. This expands the application scenarios of the electronic wiper system, ensures the clarity of the camera image, and thus ensures the safety of autonomous driving.

[0077] In this embodiment, when the shift lever is moved from low gear to high gear, a LIN bus control signal is generated. The LIN bus control signal serves as a first shift signal. The M first shift signals constitute a command sequence formed by M LIN bus control signals and are sent to the vehicle body controller.

[0078] It should be noted that the LIN bus control signal is a low-cost serial communication network defined for automotive distributed electronic systems. It is a supplement to other automotive multi-channel networks such as the Controller Area Network (CAN) and is suitable for applications that do not have high requirements for network bandwidth, performance or fault tolerance.

[0079] S405: If it is determined that the instruction information is ultra-high-speed wiping information, the key area on the windshield is wiped according to the ultra-high-speed wiping parameters; wherein the ultra-high-speed wiping parameters include the ultra-high-speed wiping range and the ultra-high-speed wiping speed; the ultra-high-speed wiping range is the wiping range of the electronic wiper system on the windshield, and the ultra-high-speed wiping speed is the wiping speed of the electronic wiper system on the windshield; the key area is the area on the windshield corresponding to the driver.

[0080] In this step, by scraping the key areas on the windshield according to the ultra-high-speed scraping information sent by the lever, targeted high-speed scraping of the key areas can be achieved in heavy rain weather, so as to ensure that the driver has a sufficiently clear view of the external environment, thereby ensuring the safety of car driving.

[0081] Exemplarily, the ultra-high frequency scraping range of the key area is 30°-70°, and the ultra-high frequency scraping speed is 70 times / minute.

[0082] The present application is compatible with the existing electronic wiper system's levers and gears. It only requires updating the wiper software in the electronic wiper system, that is, enabling the electronic wiper system to recognize the command sequence of the LIN bus control signal based on the lever operation, thereby realizing extended wiping functions such as ultra-high frequency wiping or camera area wiping. There is no need to add new lever gears or redefine the body LIN bus control signal, avoiding the need to modify the car's body controller or lever due to the expansion of the electronic wiper system's functions, resulting in excessively large car modification projects and the inability to realize the functional expansion of the electronic wiper system on a large scale.

[0083] In a preferred embodiment, the ultra-high-speed scraping information is indication information generated by the vehicle body controller receiving N second toggle signals sent by the toggle lever within a preset second time, where N is a natural number greater than 1;

[0084] The second shifting signal is a shifting signal of the shift lever from the low gear to the high gear.

[0085] In this example, the length of the second time is set as needed, for example, 3 seconds; and the number N of the second dial signals to be sent is set as needed, for example, 2 times;

[0086] Therefore, if the vehicle body controller receives two consecutive second toggle signals within three seconds, it sends an instruction to trigger the electronic wiper system to wipe key areas in a targeted manner. This expands the application scenarios of the electronic wiper system, ensures the driver's field of vision in heavy rain, and thus ensures vehicle driving safety.

[0087] In this embodiment, when the shift lever is switched from low gear to high gear, a LIN bus control signal will be generated, and the LIN bus control signal will serve as the second shift signal. The M second shift signals will constitute a command sequence formed by M LIN bus control signals and be sent to the body controller.

[0088] S406: When wiping the camera area or the key area, if the exit information sent by the body controller is received, the field of view area of ​​the windshield is wiped or stopped according to the normal parameters; wherein, the normal parameters include low-speed parameters and high-speed parameters; the low-speed parameters are the wiping speed of the electronic wiper system for the field of view area when the lever is in low gear; the high-speed parameters are the wiping speed of the electronic wiper system for the field of view area when the lever is in high gear; the field of view area is the area on the windshield used by the driver when observing the external road conditions.

[0089] In this example, if the driver wants to exit wiping the camera area or the key area, he only needs to operate the lever to generate the exit information. The operation is simple and does not change the car's body controller and lever, achieving the technical effect of quickly and conveniently exiting the camera area and wiping the key area.

[0090] In this embodiment, the range of the sight area is larger than the range of the camera area, and the range of the sight area is larger than the range of the key area.

[0091] In a preferred embodiment, the exit information is an indication information generated by the vehicle body controller when it receives a third toggle signal sent by the toggle lever; the third toggle signal is a toggle signal for switching from a high gear to a low gear.

[0092] In this example, when the electronic wiper system is wiping the camera area or the key area, it is only necessary to toggle the lever to any gear position to generate a third toggle signal to exit wiping the camera area or the key area, which is simple to operate.

[0093] In a preferred embodiment, wiping or stopping the windshield's viewing area according to conventional parameters includes:

[0094] If it is determined that the third toggle signal in the exit information is a switch from high gear to low gear, the sight area is scraped according to the low gear parameter.

[0095] In an optional embodiment, wiping or stopping the windshield's viewing area according to conventional parameters includes:

[0096] If it is determined that the third toggle signal in the exit information is a switch from a low gear to a high gear or from a stop gear to a high gear, the sight area is scraped according to the high-speed parameter;

[0097] If it is determined that the third toggle signal in the exit information is to switch from the high gear to the stop gear or from the low gear to the stop gear, then the wiping of the windshield is stopped.

[0098] In this example, if the driver wants to quit wiping the camera area or the key area and wipe the windshield's sight area at a high speed, the driver can switch by simply moving the lever to the high speed.

[0099] If you want to stop wiping the camera area or critical area and wipe the windshield at a low speed, you can switch by simply moving the lever to the low speed gear.

[0100] If the driver wants to stop the electronic wiper system, he or she can do so by simply moving the paddle shifter to the stop position.

[0101] For example, the wiping range of the field of view of the wiper rod of the electronic wiper system is 0°-110°, the high-speed parameter is 60 times / minute, and the low-speed parameter is 40 times / minute.

[0102] See also Figure 5 and Figure 6 , Figure 5 The figure shows the relationship between the wiper stalk's wiping range, wiping speed, and stalk's wiping gear position when the electronic wiper system wipes key areas of the windshield according to ultra-high-speed wiping parameters.

[0103] Figure 6 The figure shows the relationship between the wiper stalk's wiping range, wiping speed, and wiping gear position when the electronic wiper system wipes key areas on the windshield according to camera wiping parameters;

[0104] Among them, the scraping range is the amplitude of the sinusoidal waveform in the schematic diagram, and the scraping speed is the frequency of the sinusoidal waveform. The frequency of the sinusoidal waveform corresponding to the low speed gear is 40 times / minute (40cpm), and the frequency of the sinusoidal waveform corresponding to the high speed gear is 60 times / minute (60cpm). The frequency of the sinusoidal waveform corresponding to the camera scraping speed is 60 times / minute, and the frequency of the sinusoidal waveform corresponding to the ultra-high frequency scraping speed is 70 times / minute.

[0105] The scraping brush gear is the pulse band of the pulse waveform in the schematic diagram, wherein the pulse band corresponding to high is the high speed gear, the pulse band corresponding to low is the low speed gear, and the pulse band corresponding to off is the stop gear.
