SOTIF Case Study : Building a Safe Automated Driving System Functionality

by Dr.Juan Pimentel,Gregory Gruska,Nikhil Unnikrishnan published on March 03, 2022

The automotive industry continues to develop ADAS (advanced driver assistance Systems) and automated driving systems called ADS (automated driving systems). Achieving a high level of driving automation of ADS is a challenging endeavour that slows the availability of automated vehicles at levels 2, 3, and 4 in the SAE automation level hierarchy. One strategy to design highly automated vehicles is to carry out the design process by vehicle feature.

Well known vehicle features include:

HWP: Highway pilot (also known as a highway chauffeur)
TJP: Traffic Jam Pilot
CYP: City Pilot
AVP: Automated Valet Parking

The HWP feature is a robot chauffeur (i.e., the ADS) relieving a human driver from driving functions under certain conditions while the vehicle is on a highway. HWP can be designed at levels 3, 4, or 5 and in this case study, we will consider only level 3 functionality.
