A Brief Paper on Improving Active Safety Systems Via HMI and Dependability Analysis

As new active safety systems are introduced in vehicles it is important to assure correct functionality also in the presence of faults. If faults are not considered in the design of such systems, the claimed safety benefits may be compromised. It is also important to take a holistic view in the design due to the close interaction between the driver and the control systems. There exist techniques for minimizing and tolerating faults in control systems and the design of interfaces for HMI (human-machine-interaction) can be aided by models of human behaviour. This paper outlines on-going research on this close interaction between the driver and the vehicle with the aim of improving safety. The overall methods for attaining improved safety is to apply techniques for minimizing and tolerating faults in active safety systems based on recommendations from analysis of dependable systems and driver behaviour.
