Abstract
An energy management system is provided for use with a hybrid energy off-highway vehicle traveling on a predetermined course. The energy management system includes an energy management processor to determine a power storage parameter, a power transfer parameter, and an engine transfer parameter for each location along the predetermined course to minimize the total fuel consumed of all fuel types during the predetermined course subject to at least one fuel parameter constraint. An energy storage system selectively stores electrical energy available from the traction bus as a function of the power storage parameter and selectively supplies secondary electric power from the stored electrical energy to the traction bus as a function of the power transfer parameter. The engine selectively supplies primary electric power to the traction bus at each location along said predetermined course through selectively using at least one fuel type in response to said engine transfer parameter.
