Modeling the decision process of the lane-change maneuver using a situation-operator model

This contribution demonstrates the application of a situation-operator modeling (SOM) technique to the modeling of the lane-change maneuver including the decision and planning process. The core of the approach is the assumption that changes of the world are understood as a sequence of scenes and actions. These parts are modeled using a special situation and operator calculus. The presented example describes the system vehicle-environment, whereby the vehicle is driving on a multilane road and different goals, e.g. drive as fast as possible, are provided. With the description of the real system as situation-operator model, planning of actions according to the goal is realized, i.e. which action has to be applied in which situation depending on the given goal. The decision is not necessary rule-based, it follows directly from the situation. Furthermore, this formulation is independent of the given goal
