Design and development of smart automatic windshield wiper system: fuzzy logic approach
According to the authors of the articles, there are a lot of disadvantages involved when a
driver uses a manual wiper. Since the wipers are meant to help the driver’s visibility during
precipitation, there needs to be ease of use and automation of the wipers would help. In their
article, Bansode, Rajankar, & Ghatule, (2012), discuss how to develop an automatic wiper
through the use of the fuzzy logic approach. The wiper in questions should be able to
automatically start wiping the windshield once the rain starts and change its wiping speed with
the intensity of the rain up to the point where the precipitation ends completely.
In fuzzy logic, a system can gradually change its speed or intensity over a series of values
that have been set. In this case, the automatic car wiper will be able to change its wiping speed
depending on the intensity of the rain. Senses will be placed on the windshield of the vehicles to
since the intensity of the rain. A programmable chip within the car wiper systems will then be
programmed to ensure that the wiping intensity increases with the intensity of the rain and also
reduce with the reduction in the rain intensity. The systems will include the use of a peripheral
interface controller. Secondly, a grid sensor will be installed on the windshield, and lastly, a DC
motor that will be used to generate the movements of the wiper itself.
There are strengths associated with the fuzzy logic approach for designing the automatic
car wiping systems. Programmable chips to be used are very reliable and do not have fatigues as
humans have. Unlike humans who suffer fatigue and have impaired decision-making capacity
during an intense activity such as heavy rain over long hours; the use of a programmed chip will
reduce this risk. Programmed electronics do not suffer wrong decisions under pressure or fatigue.
This will help improve road safety during precipitation periods. Since the use of the fuzzy logic
approach will not require the driver to engage any manual controller. This means that the driver
will only be involved in driving the vehicle. Thus the reduction in time and brainpower needed to
constantly monitor the intensity of the rain to engage the correct wiping speed.
The automation of the wiping system reduces t...
