Vehicle Energy Management Optimization using Look-Ahead Three-Dimensional Digital Road Geometry

Three-dimensional (3D) digital road geometry provides look-ahead road topography that can enable vehicle energy management optimization. This paper discusses the value associated with 3D digital road geometry and the role it plays in support of these applications. After a brief 3D digital road geometry description, this paper will examine the results achieved from two vehicle energy management projects: the powertrain optimization of commercial vehicles and the power management optimization of hybrid electric vehicles (HEV). These results clearly show that the integration of 3D road geometry as a predictive sensor into optimized vehicle energy management systems can improve energy efficiency by approximately one to six percent.
