Publication number: 20100255952Abstract: In a vehicle having a manual transmission coupled to an internal combustion engine via a first clutch, the first clutch is operable responsive to movement of a clutch pedal. In an engine mode of vehicle operation, the engine propels the vehicle responsive to movement of an accelerator pedal. An electric motor is coupled to the manual transmission for propelling the vehicle in an electric traction motor mode of vehicle operation. Controls are configured for generating a motor demand signal responsive to accelerator pedal position and configured for modifying the demand signal generation responsive to the clutch pedal position.Type: ApplicationFiled: March 26, 2010Publication date: October 7, 2010Applicant: ZERO EMISSION SYSTEMS, INC.Inventors: Joel Craig Diehl, Dan Warner Harris, Warner Allen Harris, Warner Olan Harris, Wayne Turnbow

Publication number: 20090240388Abstract: 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.Type: ApplicationFiled: March 11, 2009Publication date: September 24, 2009Applicant: Zero Emission Systems, Inc.Inventor: Warner Olan Harris

Publication number: 20090229281Abstract: According to one form of the invention, an auxiliary system is provided for supplying air conditioning to the cabin of a truck. The system includes an air conditioning compressor having a jackshaft mounted on a hub of the compressor. The system further includes an electric motor connected to the jackshaft by a belt for the motor, wherein the electric motor has a drive shaft and a pulley rigidly secured thereon, i.e., with no clutch and with no provision for slippage of the pulley relative to the drive shaft. The jackshaft has a pulley thereon for the electric motor drive. An end of the jackshaft that is not proximate to the compressor is rotatably held by a bearing and a bearing bracket in order to increase capability of the jackshaft to withstand side loading.Type: ApplicationFiled: May 20, 2009Publication date: September 17, 2009Applicant: ZERO EMISSION SYSTEMS, INC.Inventor: Warner Olan Harris

Publication number: 20080243324Abstract: A vehicle has an internal combustion engine (ICE) and a electric traction motor (ETM) coupled by a standard transmission through a differential to drive traction wheels. A control system receives sensor signals including speed sensors, a load sensor, and an incline sensors. The control system processes the speed signals to generate indicator signals corresponding to speed of the ETM, the vehicle speed, the shifting gears and the speed of the transmission output shaft. One or more displays present indications of when the speed of a shifting gear corresponding to the speed of the ETM matches the speed of the vehicle thus the speed of the transmission output shaft.Type: ApplicationFiled: April 1, 2008Publication date: October 2, 2008Applicant: Zero Emissions Systems, Inc.Inventor: Warner Olan Harris
