Description Optimal energy consumption and recovery for electric vehiclesA central goal of OpEneR is the investigation of an innovative and highly efficient overall energy manager that uses information from underlying subsystems to generate optimal driving and operation strategies. The strategies will vary from time optimised up to range maximised. An advanced and intuitive HMI display will encourage and support the driver to control an electric vehicle for optimal en-ergy efficiency, in a comfortable and safe way. Significantly improved vehicle range estima-tions will be computed, with the use of 3D digital map information. Furthermore, opti-mised vehicle deceleration profiles for best energy recuperation and safety will be investi-gated. An enhanced simulation tool chain will be built-up to allow both the virtual develop-ment and the validation of new OpEneR Tech-nologies, with respect to energy efficiency, enhanced HMI concepts and safety. Radar sensors and video cameras will be used to monitor vehicle surroundings, define smooth driving strategies, plan driving corridors, sup-port lane keeping, and to detect road signs and objects.
