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.
