Start year: 2009

Summary: This project will develop a theoretical basis for the quantitative analysis of the dynamic performance of an on-road vehicle with uncertain system parameters and road inputs. The vehicle model is considered as nondeterministic to account for the uncertainties in its inertia properties, tyre stiffness and friction, and road conditions. Novel computation-efficient solution methods will be formulated to investigate the effect of uncertain parameters on the system's dynamics taking into account off-normal working conditions. The analytical models will be vigorously evaluated through simulation and experiment. The research intends to provide engineers with reliable methods for designing safer vehicles, thereby reducing road deaths and injuries.
