[0041] In order to make the purpose, technical scheme and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with 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] Embodiment 1:

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

[0044] Methods include:

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

[0046] S104: If it is determined that the instruction information is camera scraping information, scraping the camera area on the windshield according to the camera scraping parameters; wherein the camera scraping parameters include a camera scraping range and a camera scraping speed; the camera scraping range is the scraping range of the electronic wiper system on the windshield, and the camera scraping speed is the scraping speed of the electronic wiper system on the windshield; the camera 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 an ultra-high-speed wiping range and an 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 scraping the camera area in a targeted manner is achieved, thereby 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 lever and gear positions. It only needs to update the wiper software in the electronic wiper system, that is, to enable 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 gear positions or redefine the body LIN bus control signal, thus avoiding the problem of modifying the car's body controller or lever due to expanding the function of the electronic wiper system, resulting in excessively large car modification projects and the inability to realize the function expansion of the electronic wiper system on a large scale.

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

[0052] Exemplarily, 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 an important part of automobile engineering. It is used as an electronic control unit (ECU) to control the body electrical system. It is an electronic device that integrates multiple control functions. It receives input information from sensors or other devices and converts this information into signals that can be received by the microprocessor. By storing, calculating, analyzing and processing this information, the body controller can perform a series of control operations, such as power management, lighting control, wiper system control, central door lock and remote control reception control, body and engine anti-theft control, etc. In this embodiment, the body controller can control the operation of the wiper motor, realize the low-speed, high-speed, intermittent operation of the front wiper and the front windshield spraying functions. At the same time, it can also automatically identify the rainfall according to the signal of the optical rain sensor and adjust the working mode of the wiper.

[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 parameters.

[0057] The automatic gear is used to control the electronic wiper system to intermittently wipe the field of view 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 2s 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] Embodiment 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 3The wiper gear positions of the lever used in the wiper system control method are schematically shown. A represents the single wipe gear, B represents the stop gear, C represents the spray and wipe gear, D represents the low speed gear, E represents the high speed gear, and F represents the spray button. The wipe gear is automatically reset after wiping once, that is, it automatically stops after wiping once.

[0063] Figure 4 The present invention provides a specific method flow chart of a wiper system control method provided by an embodiment of the present invention. The wiper system control method is characterized in that the method is used to control the electronic wiper system to wipe the windshield when it is operated in the electronic wiper system of the vehicle. The lever is a terminal device used to control 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, 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 the second wiping range and the second wiping speed sent by the central control screen of the car, and 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 lever and used to generate instruction information according to the movement of the lever.

[0069] It should be noted that the body controller is an important part of automobile engineering. It is used as an electronic control unit (ECU) to control the body electrical system. It is an electronic device that integrates multiple control functions. It receives input information from sensors or other devices and converts this information into signals that can be received by the microprocessor. By storing, calculating, analyzing and processing this information, the body controller can perform a series of control operations, such as power management, lighting control, wiper system control, central door lock and remote control reception control, body and engine anti-theft control, etc. In this embodiment, the body controller can control the operation of the wiper motor, realize the low-speed, high-speed, intermittent operation of the front wiper and the front windshield spraying functions. At the same time, it can also automatically identify the rainfall according to the signal of the optical rain sensor and adjust the working mode of the wiper.

[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, by scraping the camera area on the windshield according to the camera scraping information sent by the lever, the technical effect of scraping the camera area in a targeted manner is achieved, thereby ensuring the transparency of the camera area and further ensuring the clarity of the external environment captured by the camera.

[0072] Exemplarily, 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 the 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 switch 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 the first toggle signal three times in a row within three seconds, it sends an instruction message to trigger the electronic wiper system to wipe the camera area in a targeted manner. This expands the application scenarios of the electronic wiper system, ensures the clarity of the camera shooting, and further ensures the safety of the vehicle's automatic driving.

[0077] In this embodiment, pulling the lever to switch the gear from low gear to high gear will generate a LIN bus control signal, which will serve as the first pull signal. The M first pull signals will form a command sequence formed by M LIN bus control signals and be sent to the 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 on 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 field of 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 lever and gear positions. It only needs to update the wiper software in the electronic wiper system, that is, to enable 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 gear positions or redefine the body LIN bus control signal, thus avoiding the problem of modifying the car's body controller or lever due to expanding the function of the electronic wiper system, resulting in excessively large car modification projects and the inability to realize the function expansion of the electronic wiper system on a large scale.

[0083] In a preferred embodiment, the ultra-high speed scraping information is the 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 for the shift lever to switch from a low gear to a 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 dialing signals to be sent is set as needed, for example, 2 times;

[0086] Therefore, when the body controller receives the second toggle signal twice in a row within 3 seconds, it sends an instruction message to trigger the electronic wiper system to wipe the 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, pulling the lever to switch the gear from low gear to high gear will generate a LIN bus control signal, which will serve as the second pull signal. The M second pull signals will form 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 vision 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 vision area when the lever is in the low gear; the high-speed parameters are the wiping speed of the electronic wiper system for the field of vision area when the lever is in the high gear; the field of vision 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 will not change the body controller and lever of the car, thus achieving the technical effect of quickly and conveniently exiting the camera area and the key area wiping.

[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 indication information generated by the vehicle body controller receiving 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 wipes the camera area or the key area, the third toggle signal can be generated by simply moving the lever to any position to exit the camera area or the key area, which is simple to operate.

[0093] In a preferred embodiment, wiping or stopping the sight area of ​​the windshield according to conventional parameters includes:

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

[0095] In an optional embodiment, wiping or stopping the sight area of ​​the windshield 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 a switch from a high gear to a stop gear or a switch from a low gear to a 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 sight area of ​​the windshield 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 the critical area and wipe the windshield in the low-speed gear, you can switch by simply moving the lever to the low-speed gear.

[0100] If the driver wants the electronic wiper system to stop working, he or she can switch it by simply moving the lever to the stop position.

[0101] Exemplarily, the wiping range of the sight area of ​​the wiper rod of the electronic wiper system is 0°-110°, the high-speed gear parameter is 60 times / minute, and the low-speed gear parameter is 40 times / minute.

[0102] See also Figure 5 and Figure 6 , Figure 5 The figure shows the relationship between the wiping range, wiping speed and wiping gear position of the wiper lever when the electronic wiper system wipes the key area on the windshield according to the ultra-high-speed wiping parameters;

[0103] Figure 6 The figure shows the relationship between the wiping range, wiping speed and wiping gear position of the wiper lever when the electronic wiper system wipes the key area on the windshield according to the 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 and brushing 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.
