We present a dynamic stability and agility study of a pendulum-turn vehicle maneuver. Instead of optimizing the controlled inputs to mimic expert human driver performance, we focus on understanding the stability and agility performance of the vehicle motion using professional racing car driver testing data. We propose to use the rear side slip angle, rather than the vehicle mass center side slip angle,...
This paper studies a framework of controlling a system with multiple interactive control loops including a continuously activated primary loop and discretely activated secondary loops. The structure of the controller in the primary loop is unknown while its output is observable and the controllers in secondary loops are subject to design such that the control performance of the primary loop can be...
This paper studies to characterize driver driving behavior or driver control structure in real time. The three proposed methods use some of the signals such as the driver actuation measurements, the relative ranges between a leading and a following vehicle during a car-following maneuver, and the vehicle dynamic responses such as the vehicle's longitudinal acceleration and deceleration. All the used...
This paper presents a novel approach to developing a driver advisory system that can warn the drivers of driving conditions close to the limit of vehicle handling. This advisory system utilizes intelligence inferred from vehicle states, measured signals, and the other computed variables used for active safety and vehicle control purposes. The onboard computing resources, algorithms, and sensors used...
