International Classification:

F02M 2507

US Classification:

Abstract:

A method of controlling exhaust gas recirculation by means of an EGR valve ( ). An electromagnetic actuator ( ) is associated with a housing ( ) to transmit movement of an actuator output ( ) into reciprocating movement of the EGR valve in response to changes in an electrical input signal ( ), and the method comprises generating ( ) a compensator gain value to modify the electrical input signal ( ). The improved method provides a valve position sensor ( ) and generates a position signal ( ) representing instantaneous valve position. The next step is storing ( ) a first relationship (DC ) of the electrical input signal ( ) required to change the instantaneous valve position, then, during ongoing operation, generating ( ) a then-current, second relationship (DC) of the electrical input signal ( ) required to change the instantaneous valve position. Next is comparing ( ) the second relationship (DC) to the first (DC ) and generating ( ) a corresponding difference factor, then using ( ) that difference factor to modify ( ) the compensator gain value correspondingly. This method enables the system to adapt to changes in system friction.

US Classification:

701 22, 701 51, 477110

Abstract:

A powertrain system includes an engine coupled to an input member of a transmission operative to transmit power between the input member, a torque machine and an output member. The torque machine is connected to an energy storage device. The engine is selectively operative in engine states comprising an engine-on state and an engine-off state. A method for controlling a powertrain system includes determining a first power range for output power of the energy storage device, commanding the engine to transition from a first engine state to a second engine state, and expanding the first power range of the energy storage device and controlling the torque machine based upon the expanded power range of the energy storage device during the transition from the first engine state to the second engine state.

International Classification:

G06F 7/00

US Classification:

701 54, 701 51

Abstract:

A method for operating an engine includes defining a two-dimensional search region based upon an input power transmittable between the internal combustion engine and an electromechanical transmission. The method further includes iteratively dividing the two-dimensional search region into a plurality of subregions based upon one of the input power and the input speed, iteratively determining an engine operating point within each of the subregions, iteratively calculating an operating cost to operate the internal combustion engine and the electromechanical transmission to meet the operator torque request for each engine operating point within each of the subregions, and iteratively identifying the subregion having a minimum operating cost to meet the operator torque request. A preferred engine operating point is determined based upon the engine operating point within the identified subregion having the minimum operating cost to meet the operator torque request.

Abstract:

A hybrid powertrain system includes a transmission operative to transfer power between an input member and a torque machine and an output member coupled to a driveline coupled to a wheel including an actuable friction brake. The torque machine is operative to react torque transferred from the wheel through the driveline to the output member of the transmission. The torque machine is connected to an energy storage device. A method for operating a hybrid powertrain system includes monitoring an operator torque request input to an accelerator pedal, determining a minimum available power output of the energy storage device, determining a preferred output torque reacted through the output member to the driveline based upon the minimum available power output of the energy storage device, determining a regenerative braking torque capacity comprising a torque range between the preferred output torque reacted through the output member to the driveline and the operator torque request input to the accelerator pedal, and controlling operation of the hybrid powertrain based upon the regenerative braking torque capacity.
