Abstract

A vehicle has independent electric traction system (ETS) and internal combustion engine (ICE). A system controller, a data acquisition system, and a GPS system are added to the vehicle. A remote system has a data base of locations identifying emission non-attainment areas. The data acquisition system obtains the vehicle location along with parametric data related to operation of the vehicle. The remote system notifies the vehicle operator and the auxiliary control system of opportunities to obtain emission reduction credits in response to the vehicle location data and its operating status. The system controller or the operator switch between ICE operation and ETS operation in response to the vehicle location, emission reduction credit process, and parametric measurements of the vehicle operation to achieve an emissions credit result while optimizing fuel for the ICE and stored electrical potential energy for the ETS.
