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

Abstract

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.

Three Decades of Driver Assistance Systems: Review and Future Perspectives

“…Development of advanced DAS may be stimulated by market acceptance or stunted by societal reservations (Krüger 2008, Karmasin 2008). On the other hand DAS -particularly those with a high degree of vehicle automation -may induce changes in traffic behavior (Freyer 2007et al, Freyer 2008. Furthermore, advanced DAS may stimulate new business models and have a drastic impact on the nature of future mobility.…”

“…SC 6 in table I; "SC" = Scenario) without V2X-communication. Similarly, Freyer et al [16] try to improve the ACC behavior in scenarios as in SC 6 and SC 9 in table I, by incorporating a situation analysis and a behavior prediction of the lane changing behavior of other traffic participants.…”

Coordinated Adaptive Cruise Control System With Lane-Change Assistance

“…This deceleration would introduce disturbances to the driver's usual lane-change behavior, and lane changes would be required in advance. They proposed automatic lane change to solve this problem and also designed the controller [7]. Kim et al proposed an ACC and collision avoidance (CA) system with lane-change support, which mainly consisted of a driving decision system, an adaptive cruise controller with an emergency brake function, and a steering controller with lane-change support.…”

“…On the other hand, except for the throttle and brake pedal, automated lane change also requires that the steering wheel be controlled, which is beyond ACC's control range, and the differences in operation of the two systems may confuse the driver. Moreover, the automatic controller designed in [7] and [8] assumed that the lateral trajectory was similar to sine wave or trapezium, and the longitudinal speed was constant. They ignored the longitudinal change, but this could not satisfy the real driving environment.…”
