Project

This pre-study builds on earlier development project, namely 'overspeed on curves' which was limited to a single scenario – straight-line approach to a curve – with an automatic brake intervention. This provided the lower level control intervention. This new pre-study is aimed at a more realistic scenario of  a system to trigger and implement a brake-based driver support system to prevent lane or road departure: the system will be capable of responding to environmental variables (friction, road geometry, shoulder width, etc.) as well as local vehicle variables (vehicle dynamic states, position and velocity relative to a local map). The concept is to include a predictive component that takes account of combined steering and braking, and only intervenes when it becomes fully necessary to avoid a serious lane/road departure event. The previous work on Parabolic Path Reference is at the core of this new predictive algorithm.
