  1. Frenet Vehicle Kinematics

    Defines the vehicle's Frenet state through the closest-point projection of the rear-axle center, derives a three-state time-domain model and a two-state reference-path-arc-length-domain model under the no-sideslip kinematic assumption, and explains arc-length conversion, the coordinate validity domain, and sign conventions for reversing.

  2. Planar Frenet Frame

    Defines the unit tangent, left unit normal, and signed curvature of a planar reference path; derives the Frenet differential relations from both the orthonormal-frame and path-heading representations; and establishes consistent geometric and sign conventions for vehicle kinematics in Frenet coordinates.

  3. Closed-Loop Control Timing

    An interactive timing diagram of the periods, phases, and delays among steering-feedback generation, upper-level decision updates, command transmission, and lower-level updates in autonomous lateral control, together with the simplifications this timing abstraction makes relative to a real steering system.
