Endowing advanced driver assistance systems with fault tolerance

Partly or fully autonomously driving vehicles constitute one of the greatest challenges of contemporary technology. Despite the advances achieved by automobile manufacturers so far, a lack of functional safety and reliability is observable, especially if this technology is used by untrained and possibly naive operators, as intended in everyday use. Therefore, we present a comprehensive set of known fault tolerance methods that we exemplify with advanced driver assistance systems. Not restricting ourselves to hardware issues, we pay special attention to derivatives of the programming language PEARL enforcing fault tolerance in the field of safety–critical vehicle software.
