Curvature vs steering angle

WebThis more complicated, but more accurate, model allows the controller to handle realistic dynamics. In this configuration, the controller also requires the path curvature, the current yaw rate of the vehicle, and the current steering angle to compute the steering command. WebIn formulas, curvature is defined as the magnitude of the derivative of a unit tangent vector function with respect to arc length: \kappa, equals, open vertical bar, open vertical bar, start fraction, d, T, divided by, d, s, end fraction, close vertical bar, close vertical bar.
