Control authority transition system, half-car platform, vehicular simulator and dynamic switching analysis between the human being and driver assistance system

The Control Authority Transition (CAT) system project (supported by The OSU Center for Automotive Research and Intelligent Transportation Consortium) has led to emulation of the control authority transition algorithms in the physical half-car environment through The Ohio State Virtual Environment System (OSU-VES). By creation of the artificial traffic environment and possible accident hazards scenarios, the CAT system´s interventions to the "inattentive" or "inadequate" drivers are under consideration. The development and improvement of the CAT, OSU-VES and half-car platform is a test-bed for the study of driver´s perception-reaction time, behavior, driver-vehicle interactions, crash avoidance maneuvers, advanced safety systems, and Intelligent Transportation System technologies.
