Özet

Vehicle dynamics modeling is commonly used to analyze roll, pitch, and yaw angles resulting from

vehicle maneuvering, road surfaces, and road profiles in order to improve a vehicle's road holding.

Researchers begin with a simpler model, a two-degree-of-freedom (2DoF) vehicle model, for control

system design without parameters such as vertical forces, brake pressure, and wind effects acting on a

vehicle. Studies have shown that designing the control system by making predictions on the model will

improve its performance in controlling the system with less computational load. The best results for

estimation are obtained using the Recursive Least Squares (RLS) algorithm and the Kalman Filter. The

RLS algorithm is used for parameter estimation, such as vehicle tire parameters, while the Kalman Filter

is used for state estimation, such as lateral velocity and yaw rate, yielding more accurate results. In this

study, using a 2DoF vehicle model, the performance of the RLS algorithm and Kalman Filter in

estimating lateral and yaw rates during sudden maneuvers on dry, wet, and icy road surfaces was

observed at a basic level. The results show that when these two methods are used in an integrated manner

in parameter estimation and lateral velocity estimation, satisfactory results are obtained.
