SOTIF Case Study : Building a Safe Automated Driving System Functionality
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.
