1. RATIONALE
Since last few decades, car designers have turned to high technology in order to meet ever
more stringent emission control, ergonomics, safety regulations and the demands of
customers for better cars at global level. Multi-modal transportation become increasingly
common and intelligent vehicles will cater to diverse consumer needs for information,
environmental responsibility and safety. Vehicle electronics contribute significantly to
improve environmental performance of motor vehicles and are, therefore, an important
enabler of “green” vehicle technology. Electronics offer improved control to a variety of
vehicle systems, allowing for more efficient operation of engines and other power trains,
heating and cooling systems etc., resulting in less fuel or other power consumed and thus,
lower harmful emissions. Today’s complex hybrid power trains could not be operated and
managed without an array of electronics, including sensors, controllers and actuators.
Furthermore, replacement of mechanical components with electronic components tends to be
lighter, again leading to less demand for fuel and power options. This course aims to provide
understanding of importance of multidisciplinary knowledge in application by appreciation
about role of sensor, actuator and electronics components for modernization of automobile.
2. COMPETENCY
