Fault Injection in Model-Based System Failure Analysis of Highly Automated Vehicles

The active safety control systems of highly automated vehicles for SAE level 3 and higher are still not fully developed and facing some unresolved issues. The deployment of automated driving systems and the functional safety development present challenges in driver – machine control relat...
