Simulation of Smart Sensors in Automobile using VHDL

Due to the advancements in Wireless Sensor network, smart sensors are used in various new and upcoming applications such as smart home appliances, water & air quality application and extensively in automobiles. In Automobiles, WSN and smart sensors are used for many applications such as Vehicle Security & Locking. Earlier, the most security the vehicles had was a locked door, but now days they are equipped with the electronic security system which consists of alert systems and theft alarm system. This paper is an attempt to show how sensors have replaced use of switches in car doors and its limitations to alert the person. The simulation work demonstrates the efficiency of sensors in securing vehicles in case of recklessness. Sensors are also used in the Automobile electronic injection system, in this the sensors used in the fuel injection system determine the exact time the fuel should be injected and the exact amount that is to be injected, due to this the emission gases have reduced by 50%, fuel economy and the power output has increased by about 45-65% and 30-55% respectively. Another use of sensors is in Advanced Headlight Technology, in this there are different electronic and reflecting technologies used that can adjust and even bend light along curved path for better visibility during night time, etc. This paper also explains smart sensors and some of its applications in automobile as listed above.
