ACC with enhanced situation awareness to reduce behavior adaptations in lane change situations

This paper describes a refined lane change support function to enhance current Adaptive Cruise Control (ACC). Its design is based on a field experimental highway study in which experienced participants were asked to drive first without and afterwards with ACC support. The first condition serves as a baseline to identify different driving styles (fluid, moderate, and comfortable) within the sample and to describe the drivers' manual lane change behavior. By contrasting both experimental conditions, it is analyzed how the lane change behavior is altered by ACC and a situation aware ACC system with a lane change support function is described.
