On qualitative and operational reliability of electronic brake systems for heavy duty vehicles

The development of the safety critical systems of future commercial vehicles is mainly driven by the social demand, that the societies want to see safer, more reliable vehicles on the roads, which can also handle more complex situations than human driver can. It is questioned whether the approaches of the classical reliability theory are appropriate for redundant electronic systems, especially if they have a safety-critical nature, such as the electronic brake system, which has been used in commercial vehicles in Europe for almost a decade
