How to design accurate kinematic models for real time applications? To provide a general idea to the flow of text in the upcoming chap-. The subsequent sections in the chapter study kinematic and dynamic models for lateral vehicle motion. model systems arise naturally in a number of instances, including those arising in cases traditionally addressed using the Power Dissipation Method (PDM). The kinematic parameters (the ICR coefficient ï, the path curvature variable ã and robot speed R), including the effect of vehicle dynamics, are introduced to describe the kinematics model.
