There are typically multiple speed options, including fast, medium and slow. Rain sensing functionality based on rainfall sensor 102: some modern automobiles are equipped with rain sensing windshield wiper 104 systems that can automatically adjust the speed of windshield wiper 104 based on sensed rain intensity. In this way, the windshield wiper 104 will work automatically when needed without manual operation by the driver. Cleaning function: the windshield wiper controller 101 also typically includes a cleaning water spray function that allows the driver to spray cleaning fluid onto the windshield using a water spray to help clean up more stubborn dirt.

In this embodiment, the driver operates the windshield wiper control terminal 103 to the automatic gear, so that the rainfall sensor 102 is turned on; if the windshield wiper controller 101 detects that the rainfall sensor 102 is turned on, the windshield wiper controller 101 will enter the automatic wiping scenario, at this time, the windshield wiper sensor will detect the rainfall of the environment where the automobile is located, generating the wiping frequency at which the windshield wiper 104 should wipe the specified area according to the rainfall, and sending the frequency command recording the wiping frequency to the windshield wiper controller 101, the windshield wiper controller 101 controlling the windshield wiper 104 to wipe the windshield of the automobile according to the wiping frequency, at this time, the windshield wiper controller 101 enters the first wiping state, and the first wiping state is the windshield of the automobile wiping mode in the automatic wiping scenario.
If it is detected by the automobile speed sensor that the current automobile speed of the automobile exceeds the automobile speed threshold and/or if it is determined that the rainfall of the environment where the automobile is located is lower than the preset rainfall threshold, the rainfall of the environment indicates that the automobile can flush rainwater on the windshield of the automobile through the current speed; at this time, if the automobile is in the rainstorm mode again, interference will be caused to the driver, and therefore, the rainstorm mode will be stopped; meanwhile, by setting the rainfall threshold, the rainfall of the environment indicates that if the rainfall of the environment where the automobile is located is smaller than the rainfall threshold, it indicates that the automobile does not need to be kept in the rainstorm mode.
If the temperature sensor detects that the current temperature of the windshield wiper 104 exceeds the temperature threshold, it indicates that the current temperature of the windshield wiper 104 is relatively high, and in order to prevent the windshield wiper 104 from being damaged, the rainstorm mode is stopped to ensure the safety of the windshield wiper 104.
If the windshield wiper controller 101 receives the central control conventional signal sent by the central control display screen 105, it indicates that the driver wishes to exit the rainstorm mode through the central control display screen 105, and therefore, the windshield wiper controller 101 stopping the rainstorm mode, to ensure reliability of exiting the rainstorm mode.
After exiting the rainstorm mode, the automobile is likely to further need to be wiped, and in order to ensure that the sight line of the driver is still not interfered after exiting the rainstorm mode, in this embodiment, the windshield wiper controller 101 is instructed by the central control conventional signal to control the windshield wiper 104, and the windshield of the automobile is wiped at a frequency less than the maximum frequency.
In some cases, when the driver drives at a high speed, it is inconvenient to operate the central control display screen 105, and the driver may operate the windshield wiper control terminal 103 to generate a terminal conventional signal, so that the windshield wiper controller 101 exits the rainstorm mode; in order to ensure that the sight line of the driver is still not interfered after exiting the rainstorm mode, in this embodiment, the windshield wiper controller 101 is instructed to control the windshield wiper 104 through the terminal conventional signal, and the windshield is wiped at a frequency less than the maximum frequency.
If the windshield wiper controller 101 is in the first wiping state before entering the rainstorm mode, the windshield wiper controller 101 will enter the first wiping state again after exiting the rainstorm mode, so that after entering the rainstorm mode from the automatic wiping scenario and exiting the rainstorm mode again, the windshield wiper controller 101 will enter the automatic wiping scenario again to ensure the consistency of the wiping scenario.
If the windshield wiper controller 101 is in the first wiping state before entering the rainstorm mode, after exiting the rainstorm mode, the windshield wiper controller 101 will enter the first wiping state again, so that after entering the rainstorm mode from the manual wiping scenario and exiting the rainstorm mode again, the windshield wiper controller 101 will enter the manual wiping scenario again to ensure consistency of the wiping scenario.
In a preferred embodiment, the windshield wiper controller 101 is in the second wiping state, including:
The gear signal is one of a high-speed gear signal and at least one non-high-speed gear signal; the non-high-speed gear signal is command information sent by the windshield wiper control terminal 103 for instructing the windshield wiper 104 to wipe the windshield of the automobile at a non-high-speed frequency; and the valve of non-high-speed frequency is less than the high-speed frequency.
In this embodiment, the driver operates the windshield wiper control terminal 103 to a high-speed gear or a non-high-speed gear, the rainfall sensor 102 is not turned on, if the windshield wiper controller 101 does not detect that the rainfall sensor 102 is turned off, the windshield wiper controller 101 entering a manual wiping scenario, and the windshield wiper controller 101 controls the windshield wiper 104 to wipe according to the gear signal sent by the windshield wiper control terminal 103.
Exemplarily, the high-speed frequency is 60 cpm, and the non-high-speed frequencies include: 50 cpm, 40 cpm, 30 cpm, and 20 cpm; if the frequency of the received gear signal is 60 cpm, it is determined that the received gear signal is a high-speed gear signal; if the frequency of the received gear signal is any one of 50 cpm, 40 cpm, 30 cpm, and 20 cpm, it is determined that the received gear signal is a non-high-speed gear signal.
In a preferred embodiment, the windshield wiper control system further includes an automobile speed sensor and a temperature sensor; the automobile speed sensor is connected with the windshield wiper controller 101, and the automobile speed sensor is configured to detect the automobile speed of the automobile; the temperature sensor is connected with the windshield wiper controller 101, and the temperature sensor is configured to detect the temperature of the windshield wiper 104;
Before the windshield wiper controller 101 enters the rainstorm mode, the method further includes:
If the windshield wiper controller 101 determines that the current automobile speed does not exceed the preset automobile speed threshold, the windshield wiper controller 101 triggering the temperature sensor to feed back the current temperature of the windshield wiper 104.
If the windshield wiper controller 101 determines that the current temperature does not exceed the preset temperature threshold, the windshield wiper controller 101 entering the rainstorm mode.
In this embodiment, when the automobile is in a rainstorm environment and the automobile speed is fast, rainwater on the automobile window may be flushed due to high-speed driving of the automobile, and if the automobile enters a rainstorm mode at this time, the windshield wiper 104 may interfere with the field of view of the driver due to wiping on the critical area; therefore, when the current automobile speed does not exceed the speed threshold, it indicates that the automobile cannot flush the rainwater on the windshield of the automobile through the current speed, and the windshield wiper controller 101 may enter the rainstorm mode; and when the current automobile speed exceeds the speed threshold, it indicates that the automobile can flush the rainwater on the automobile window through the current speed, and the windshield wiper controller 101 does not need to enter the rainstorm mode.
Since the windshield wiper 104 in the rainstorm mode may wipe the automobile window in a high-frequency wiping manner in the critical area, the windshield wiper 104 may have a large operating burden in the rainstorm mode, and in order to avoid burning out due to an excessively high temperature of the windshield wiper 104, the current temperature of the windshield wiper 104 is collected through the temperature sensor, if the current temperature does not exceed the temperature threshold, the windshield wiper controller 101 may directly enter the rainstorm mode, and if the current temperature exceeds the temperature threshold, the windshield wiper controller 101 is rejected from entering the rainstorm mode to protect the windshield wiper 104.
For example, assuming that the temperature threshold is 80° C., if the current temperature is not greater than 80° C., the rainstorm mode may be entered, and if the current temperature exceeds 80° C., the rainstorm mode may not be entered.
In a preferred embodiment, the windshield wiper control system further includes a configuration module 107 connected to the windshield wiper controller 101.
The windshield wiper controller 101 enters a rainstorm mode, including:
If the rainstorm frequency parameter is not extracted from the configuration module 107, the windshield wiper controller 101 sets the maximum frequency value as the safety frequency.
The windshield wiper controller 101 extracts the upper angle parameter (URP-A) and the lower angle parameter (LRP+A) from the configuration module 107, and controls the lower angle parameter of the windshield wiper 104 to be a bottom dead center, the upper angle parameter is a top dead center, and the windshield is wiped at a safety frequency, where the top dead center and the bottom dead center are in a critical area on the windshield.
In this embodiment, a rainstorm frequency parameter may be set in the configuration module 107, if the windshield wiper controller 101 enters the rainstorm mode, the rainstorm frequency parameter is extracted from the configuration module 107 and set to a safety frequency, and the windshield of the automobile is wiped with the safety frequency; meanwhile, the rainstorm frequency parameter may not be set in the configuration module 107, then the maximum frequency value in the configuration module 107 is used as the safety frequency, and the windshield of the automobile is wiped with the safety frequency, so as to ensure that the wiping frequency of the windshield wiper 104 on the windshield of the automobile is at a high frequency wiping degree.
Meanwhile, the critical area is determined by setting the upper angle parameter and the lower angle parameter, so as to realize customized management of the critical area.
Exemplarily, only the wiping frequency interval [20 cpm, 60 cpm] is recorded in the configuration module 107, then 60 cpm is used as the safety frequency; if not only the wiping frequency interval [20 cpm, 60 cpm] is recorded in the configuration module 107, but also the rainstorm frequency parameter: 70 cpm is recorded, then 70 cpm is used as the safety frequency.
An angle range of the specified area is defined in the configuration module 107, for example, [LRP: 0°, URP: 90° ], where LRP is a bottom dead center of the specified area, and URP is a top dead center of the specified area. Therefore, the windshield wiper controller 101 will control the windshield wiper 104 to be wiped on the windshield at an angle range of 0°-90°, which is a specified area.
The upper angle parameter in the configuration module 107 is: 20°, and the lower angle parameter is: 70°, then the windshield wiper controller 101 will control the windshield wiper 104 to wipe on the windshield of the automobile within an angle range of 20°-70°, and the range of the windshield wiper is a critical area.
In a preferred embodiment, the windshield wiper control system further includes: a fault detection module 108; the fault detection module 108 is connected to the windshield wiper controller 101, and the fault detection module 108 is configured to detect whether a fault occurs in the automobile and the windshield wiper 104.
After the windshield wiper controller 101 enters the rainstorm mode, the method further includes:
In this embodiment, if the fault detection module 108 detects that the automobile and/or the windshield wiper 104 has a fault, if the windshield wiper controller 101 continues to be in the rainstorm mode, the automobile and/or the windshield wiper 104 may continue to be damaged, causing the fault of the automobile and/or the windshield wiper 104 to expand.
Therefore, once the fault detection module 108 finds that the automobile and/or the windshield wiper 104 has a fault, the fault detection module 108 exiting the rainstorm mode to avoid expanding the fault range or deepening the fault degree.
The fault detection module 108, commonly referred to as an automobile diagnostic module, is an electronic equipment or software tool for monitoring and detecting automobile systems, engines, and other critical components. These modules are important components of modern automobiles and are intended to identify and record automobile performance issues, faults, and error codes.
The main functions of the fault detection module 108 include: diagnosis: monitoring various systems of the automobile, such as engine, transmission, braking system, exhaust system, etc., to detect any anomalies or faults. Record fault code: when a module detects a problem, it generates an error code, called a fault code, to indicate the nature and location of the problem. These trouble codes may be used by a technician or owner for diagnosis and repair. Real-time data monitoring: the module may generally monitor and record real-time data of the automobile, such as automobile speed, engine temperature, oil pressure, air-fuel ratio, etc., to help diagnose problems and optimize performance. Warning the driver: some fault detection modules 108 may send warning signals to the driver, such as engine fault lights or other warning lights, prompting them that there is a problem requiring repair. Maintenance advice: some advanced automobile diagnostic modules may also provide repair advice, including instructing the owner or technician how to fix a particular issue. These modules typically communicate with the automobile's electronic systems through an automotive diagnostic interface, such as the On-Board Diagnostic II interface. Automotive manufacturers use different standards and protocols to implement these functions, and thus, different make and model automobiles may use different fault detection modules 108. These modules are important for quickly and accurately locating and solving automobile problems, and help improve driving safety and automobile performance.
