To estimate the potential benefits of steering evasion assist, as well as summarising established steering technologies.


Literature review

Key Findings:

  • Steering and evasion assistance systems are a new class of driver assistance systems that open up additional potentials for collision mitigation. It was shown in this chapter that steering intervention is a sensible alternative or additional option for emergency braking systems in a collision speed range above 30 km/h. Steering intervention and evasion systems especially focus on surprising situations, where fast reactions are needed and no time is left for driver warnings. This requires high demands on environment perception as well as on situation analysis. Up to now environment perception algorithms concentrate on object and lane detection and measurement. A new requirement for driver assistance is the detection of free and drivable space, which has to be guaranteed to perform an evasion manoeuvre.

  • Three different system layouts were presented: driver-initiated evasion, corrective evasion, and automatic evasion assistance. Driver-initiated evasion only supports an intervention of the driver and therefore offers less safety potential, but due to less complexity it may soon be introduced to market. Corrective or automatic evasion assistance systems are currently investigated by industry and scientific research labs. Beside technical problems like the reliability of the environment perception, a lot of open questions have to be answered, e.g., customer controllability and acceptance. Therefore market introduction is not expected within the next 10 years.
