Virtual sensor for real-time estimation of the vehicle sideslip angle Sens. Rev. (IF 1.217) Pub Date : 2019-07-29 Kanwar Bharat Singh
Purpose The vehicle sideslip angle is an important state of vehicle lateral dynamics and its knowledge is crucial for the successful implementation of advanced driver-assistance systems. Measuring the vehicle sideslip angle on a production vehicle is challenging because of the exorbitant price of a physical sensor. This paper aims to present a novel framework for virtually sensing/estimating the vehicle
