A generated guidance curve approximates a vehicle trajectory path comprising a set of two-dimensional reference points. The guidance curve is based on a summed and weighted radial basis functions. Weighting is associated with coefficients calculated using linear least-squares regression to minimize approximation error between the guidance curve and the vehicle trajectory path. Guidance instructions are based, at least in part, on a nearest location point, and a tangent direction and curvature of the guidance curve at the nearest location point. The controller autonomously guides the vehicle along the guidance curve. The basis functions can have a cardinality less than a cardinality of the reference points. A distorting effect at the path ends can be minimized by augmenting the path ends of the vehicle trajectory path. Irregular reference point spacing can be mitigated using regularization techniques."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Curved path approximation in vehicle guidance systems and methods","description":"Improved vehicle guidance systems and methods are provided.
