The vehicle attributes developed for emerging markets like India are unique because of different topographical conditions, diversity and culture within the different states. Major attributes in vehicle development process is development of safe and sustainable vehicle systems (steering, brakes etc.) for the driver. India is presently an emerging market for automotive sector. With booming economy, purchasing power of the consumer has gone up in the past few years. Most of young population of India have started buying the cars. At the same time, India’s road infrastructure, vehicle regulations have exalted over the years. The consumer cognizance towards the vehicles have started changing now. They want safer, robust system in their vehicles with new convenience features at affordable cost. In recent years, almost all OEM’s in India have migrated steering systems from HPAS to EPAS for payback on fuel economy and weight. This article discusses development of EPAS system with the following features for India market based on customer expectations and benchmark data.Assist control at different speedsActive steering returnabilityActive damping controlSoft stop- at rack bar end stroke The EPAS features mentioned above are tuned to suit the Indian road conditions and buyers need. These features play an important role to improve the driving comfort and safety. The article also covers the EPAS safety goals as per guidelines given in ISO 26262 and ASIL rating for the EPAS system based on hazard analysis and risk assessment in order to mitigate the system safety risks. Additionally it provides a short brief on reliability for the sustainable EPAS and ADAS features.
