Abstract

 Advance Driving Assistance System (ADAS) is a future of entire automobile industry, A lot of Embedded Electronic Control Units (ECU’s) are integrating into the automobiles to improve the Comfort, Safety and Security like ADAS-Vision, Radar, and Adaptive Cruise Control (ACC) etc. But as number of ECU’s are increasing there is a lot of chances for malfunctioning behavior of the system and it is having major effects on the safety of Driver, Passengers and even environment, so there is a need for evolution of system architecture from fail safe to fail operational, For this purpose there is a need of detailed safety analyses need to be carry out for mitigating or completely silencing the obtained malfunctions, ISO26262 describes the steps to be carried out for safety analyses of the system, In this paper ,following the international safety standards for automobiles designing of the fail operational architecture was discussed from the existing fail safe architecture.

Keywords: ADAS, ISO26262, functional safety, fail safe, fail operational, HARA, FSC.
