|20110202234||OVER THE ROAD/TRACTION/CABIN COMFORT RETROFIT - A vehicle includes a drive train having a manual transmission. An internal combustion engine is coupled to the manual transmission via a clutch. Auxiliary devices operate auxiliary systems of the vehicle. A battery energizes electric drivers for the auxiliary devices. A power exchange unit is coupled to the manual transmission via a power takeoff port. An electric generator is coupled to the power exchange unit, and the internal combustion engine drives the generator via the power exchange unit. The battery is energized by the generator via a battery charger.||08-18-2011|
|20110031050||ELECTRIC TRACTION SYSTEM AND METHOD - A power exchange unit (PXU) is coupled to an existing manual transmission of a vehicle via a PTO port. An electric motor generator coupled to the PXU. A battery is electrically coupled to the motor generator for supplying power to propel the vehicle. A control unit is coupled to the motor generator and the battery and configured to switch operation of the vehicle between first and second modes, wherein in the first mode an internal combustion engine of the vehicle propels the vehicle, and in the second mode the motor generator propels the vehicle in a motoring mode.||02-10-2011|
|20100065358||Electric Traction Retrofit - A drive train includes an internal combustion engine (“ICE”) coupled to a transmission having a power takeoff port. A transfer device couples an electric motor to the transmission via the port. The electric motor is enabled in a certain configuration to selectively power the drive train during at least certain intervals when the ICE is powered off.||03-18-2010|
|20090240388||DATA ACQUISITION FOR OPERATION OF A VEHICLE - A vehicle has independent electric traction system (ETS) and internal combustion engine (ICE). An 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 ET||09-24-2009|
