A vehicle motion estimating system for estimating a vehicle motion variable such as yaw rate, lateral acceleration, or side slip angle by using a mathematical vehicle model is composed of a digital device such as a microcomputer for digitally solving equations of vehicle motion of a time-varying type such as equations of yawing motion and side slipping motion, and an analog device for solving one or more time-invariant linear differential equation such as an equation of a steering system about a kingpin or an equation of rolling motion.
