A Novel IDS-based Control Design for Tire Blowout

Tire blowout, as a hazardous and inevitable event, strongly affects vehicle driving stability. In such a critical situation, improper interventions from panicked human drivers may cause severer accidents. Therefore, a dedicated automatic control design needs to be properly developed for ground vehicles to ensure vehicle stability and path following performance after a tire blowout. In this paper, a novel automatic control design of tire blowout is proposed by using the Lyapunov stability theory for impulsive differential systems (IDS). Different from the existing control designs, the proposed controller can generate not only continuous (smooth) lateral force and yaw moment control efforts, but also impulsive yaw moment control efforts to overcome impulsive disturbances from tire blowout. Results of Matlab/Simulink and CarSim^® co-simulation on a C-class vehicle indicate that, with the impulsive yaw moment control efforts, the vehicle direction can be quickly corrected and the path following performance can be largely improved after tire blowout.
