Lab VIEW Based Intelligent Braking System for Automobile Application

摘要

Increasing mobility in day-today life has led to the concern for the safety of automotives and human life. The development of intelligent driver assistance system is turning a significant element in the structure of future intelligent transportation system with the objective of reducing the no. of traffic accidents and their subsequent fatalities. The parameters derived from this intelligent system are based on passengers' safety and comfort. In this context the intelligent braking system (IBS) is proposed by modifying the antilock braking system (ABS) technology. The simulation idea uses a switching action of IBS and ABS mechanism. It employs a self tuning Fuzzy Logic Controller with a Bang-Bang Controller and ultrasonic sensor. The sensing feature in IBS technology is conceived here in the purpose of instant braking in very near range. The Bang-Bang controller implements antilock braking capability during heavy braking conditions. Therefore the IBS arrangement in an automobile provides an extra degree of freedom towards the braking mechanism. The above simulation model is formulated in graphical user interfacing software LabVIEW which yields a rapid control prototyping, real time simulation, in vehicle data logging and control and online noise, vibration and harshness testing towards the manufacturing field of the automobiles.
