Dynamic sensor, vehicle speed sensor, body vibrations sensor, air velocity transducer etc., by the collection of multiple sensor signals and
Analysis, the size of the current rainfall of comprehensive assessment, the speed of rain blown by adjust automatically windscreen wiper it is ensured that traffic safety row and driving are comfortable
Property.
Background technology
The definition of the windshield in vehicle traveling process directly affects traffic safety and ride comfort.In order to ensure
Driving vision clear, Hyundai Motor is fitted with windscreen wiper system.
Typically, the adjustment mode blowing rain speed of windscreen wiper system can be divided into two kinds：The first is manual windscreen wiper system
System, driver passes through to estimate the impact to degree of getting a clear view for the raindrop of windshield, visually result manually select different
Windscreen wiper speed stage, to remove rain mark on windshield it is ensured that getting a clear view.Second is automatic wiping system, this species
The automatic wiping system of type is typically by rain sensor, control module, rain shaving electrical machine drive system, rain shaving electrical machine, windscreen wiper machinery

Vibration that vibration, the vibration that engine operating brings, and the rapid air movement during traveling bring etc., using single
The vibration that vibrating sensor cannot be distinguished by windshield is to be led to by which kind of vibration source, therefore cannot be to raindrop impingemest windshield
The vibration signal causing effectively is identified, and then rainfall size cannot be measured, and therefore cannot realize windscreen wiper speed
Adjust automatically.There is document to propose installation damping material additional to vibrating sensor to eliminate the impact of other vibration sources, increase resistance
Damping material not only can lead to sensor that the detection sensitivity of the vibration that raindrop impingemest windshield causes is declined, and other vibration sources
The vibration leading to also cannot be completely eliminated, and therefore also cannot realize the accurate evaluation of rainfall size, thus rain brush speed cannot be realized
The adjust automatically of degree.

Fig. 2 is：Rainfall size appraisal procedure flow chart.
Specific embodiment
Below in conjunction with Figure of description, further details of theory is made to the composition of the specific embodiment of the invention and operation principle
Bright.Its composition of automatic wiping system proposed by the present invention is illustrated in fig. 1 shown below：
Ideally, the frequency of raindrop impingemest windshield wind and amplitude can reflect the size of current rainfall：Vibration frequency
Higher, vibration amplitude is bigger, shows that raindrop are bigger, more intensive, raindrop speed is faster, therefore by the Vibration Condition of windshield
The size of current rainfall can effectively be reflected, vibrational state during raindrop impingemest windshield can blow rain as windscreen wiper system
The control signal of speed adjustment.In practical situations both, the frequency of raindrop impingemest windshield and amplitude with several factors close phase
Close：As rainfall size, speed, wind speed etc..In order to the accurate size assessing current rainfall, automatic rain proposed by the present invention
Scrape the composition of system as shown in fig. 1, this system mainly by：Vibrating sensor on the windshield, vehicle speed sensor are installed（Or
Person is the GES of former car）, body vibrations sensor, air velocity transducer, microcontroller and traditional windscreen wiper system are had
Some rain shaving electrical machine drive modules, the frame for movement of windscreen wiper system.
The effect of its each part is as follows
1. windshield vibrating sensor is arranged on the front windshield of automobile, and it is used for picking up the vibration when front windshield
Signal, is monitored to the Vibration Condition when front windshield, contains what multiple vibration sources caused in the vibration signal of its pickup
The vibration of the windshield that jolting in vibration, such as vehicle travel process, wind speed change etc. cause.
2. vehicle speed sensor：Vehicle speed sensor is used for measuring current speed, and in actual system, this signal can also
Obtained by vehicle original vehicle speed measurement device.The speed leading to raindrop impingemest windshield is become by the change of speed
Change, as faster in speed, the speed leading to raindrop impingemest glass for vehicle window is increased, the amplitude of therefore its vibration can increase.Meanwhile, by
In the quick movement of vehicle, the frequency that the presence of Doppler frequency shift phenomenon also leads to raindrop impingemest vehicle window changes, therefore

3rd step：By the frequency of the windshield vibration of acquisition and the vibration signal being obtained by body vibrations sensor
Frequency is contrasted, if had in frequency content and windshield vibration signal in the vibration signal of body vibrations sensor acquisition
Frequency identical, then by the vibration signal of windshield this frequency content remove because this vibration be from car body be transmitted through come
, rather than raindrop impingemest glass for vehicle window leads to.Simultaneously by the frequency content of the vibration signal of windshield with pass through in advance
The model frequency of the storage that experiment determines windshield in the microcontroller is compared, and the vibration signal by windshield
In with model frequency identical frequency content remove.
4th step：According to the frequency in the windshield vibration signal that acquisition GES and wind velocity signal obtain to the 3rd step
Rate and amplitude are corrected.The value of the correction of amplitude and frequency can be realized obtaining by experimental technique, its correction principle

The deviation to the impact that frequency and the amplitude of raindrop impingemest windshield cause for the speed, this deviation can be used as amplitude and frequency correction
Data, and by this correction data store in the microcontroller.
5th step：According to the peak value of frequency after correction and the size of amplitude, current rainfall size is made accurately
Assessment, effectively current rainfall can accurately be estimated, and the assessment result according to rainfall size simultaneously, be selected
Suitable windscreen wiper speed, the windscreen wiper velocity amplitude of acquisition is sent to rain brush drive system, last motor system and its machinery
Structure, keeps the cleaning of windshield and driving vision, and what rain speed blown by windscreen wiper can in laboratory environments, by simulation not
With rainfall size, demarcated with getting a clear view of windshield for standard, and by the windscreen wiper velocity amplitude under different rainfall
Storage is in the microcontroller.
Rainfall size accurate evaluation is realized by existing low cost sensor utilized above, blows rain speed to realize windscreen wiper
Adjust automatically, cost can be effectively reduced, realize the automation of windscreen wiper, thus improving traffic safety and ride comfort.
