STPA based Hazard Analysis of adaptive cruise control

Overview

Goals

use STPA in a case study in the automotive domain to investigate the scenarios of accidents.

Learning Objectives

To learn to use STPA to identify hazards of a particular case of adaptive cruise control to analyse a case study

Context

We applied the STPA hazard analysis technique to Adaptive Cruise Control (ACC). ACC is an automotive feature that allows a vehicle’s cruise control system to adapt the vehicle’s speed to the traffic environment. ACC uses a long range radar sensor which is attached to the front of the vehicle and detects a target vehicle up to 150 meters in front. The ACC system is able to automatically adjust the driving speed as well as the distance to the vehicle ahead in accordance with the pre-settings
