Abstract
A dynamic slip angle estimation system and method uses measured vehicle acceleration and yaw rate parameters in estimating a tire slip angle. From load sensor(s) mounted to the vehicle tire, a tire static load estimation is made and a tire slip angle is calculated at low frequency. The vehicle center of gravity longitudinal position and yaw moment of inertia is estimated from the static load on the vehicle tires. An observer calculates tire axle forces based on the vehicle acceleration and yaw rate. From the tire axle force estimations, the vehicle moment of inertia and vehicle center of gravity longitudinal position estimate and a low frequency direct measurement of the tire slip angle, a dynamic tire slip angle calculation is made.
