Abstract :
A reliable estimation algorithm for the absolute velocity of a vehicle has been required in studies by California PATH (Partners for Advanced Transit and Highways) to design stable and robust controller for a vehicle for intelligent vehicle highway systems (IVHS). This paper investigates the feasibility of using magnetic markers, already presented for lateral vehicle guidance in IVHS, for estimating vehicle position and velocity. In this paper, the use of a hybrid observer is proposed. Vehicle longitudinal motion control based on magnetic markers is also considered and evaluated by simulations
