Visibility is a critical factor to avoid the accidents and incidents on road. Every year there are over 5 million car accidents reported in USA. Of these 23% are caused by the hazardous weather and poor visibility. Driving in poor visibility increases the potential for a serious crash. Over the last decade 15% of the accidents on road are due to poor visibility in bad weather conditions. This paper addresses the poor visibility through the rear windshield glass of a car.
A vehicle is designed in a way to provide the maximum possible visibility. But due to the vehicle design constraints, the visibility through the rear glass is very less. This visibility reduces drastically in the extreme weather conditions like rain, snow, dust and fog. At present, wiper systems play an essential role in providing better visibility for the driver in bad weather. Even though there are other technological aids like cameras, sensors etc.., they come with a high cost and act as only passive visibility for the driver. These cannot give as much confidence to the driver as his own eyes can. The wiping systems for front windshield glass, in terms of wiping area, are very efficient compared to the rear glass wiper systems. The rear wiper arm length is very less, mainly due to the height of the glass. This combined with the conventional motion of wiper arm, results in a low wiping area, leading to poor visibility for the driver. This paper addresses this problem with a simple solution using a telescopic wiper system with cam and roller mechanism.
