Considering the increase in a number of vehicles being used over the globe, we hereby look into some of the problems being faced by the drivers and also present a survey on the methods and remedies which are in practice today. The problems that are in the limelight in this paper include Fuel quantity measurement, fuel theft detection, driver drowsiness, air pressure sensing in vehicle tyres etc. The amount of fuel can be measured either by using fuel level sensors or fuel quantity detection sensors in the fuel tanks. There are various fuel level sensors currently in use in the market, for eg: ultrasonic sensors. And the fuel quantity detection sensors include load cells, which give the amount of fuel in the tanks. Driver drowsiness can be detected using motion sensors or cameras and image processing. Also, there are various sensors and methods available for measuring the tyre pressures in vehicles.
