Abstract: A vehicle includes a motor/generator, a disconnect clutch disposed between the engine and the motor/generator, and a transmission disposed between the motor/generator and the vehicle drive wheels. The transmission includes an input clutch which is selectively engagable for facilitating torque transfer between the motor/generator and the vehicle drive wheels. When an engine start is requested, the motor/generator is operated, and a start mode for the engine is determined based on a number of vehicle parameters. The transmission input clutch is partially disengaged to at least partially isolate the vehicle drive wheels from engine torque disturbances when the engine is started. The disconnect clutch is engaged, and the engine is fueled, thereby facilitating torque production by the engine.

Abstract: Systems and methods for determining the optimum number of platforms to be used in a hydrocarbon field development and their position. The systems and methods determine the least valuable platform(s) and eliminate them from use in the hydrocarbon field development.

Abstract: Systems and methods for automatically and optimally planning multiple well locations within a reservoir simulator. The systems and methods use dynamic production criteria to create and optimize well target completion intervals and the associated well geometries for new wells dynamically, and directly within a reservoir simulator.

Abstract: A method for operating a hybrid vehicle having a primary power generating system and a secondary power generating system coupled via a power transmission assembly for delivery of tractive force for the vehicle. The method includes determining acceleration of input speed to the power transmission assembly when the primary power generating system is deactivated, and inferring activation of the primary power generating system based at least in part on the acceleration of the power transmission assembly.

Abstract: A control method and system for a hybrid vehicle powertrain with an electric motor in a power flow path between an internal combustion engine and a multiple-ratio geared transmission. Motor torque, which is added to engine torque to obtain an effective transmission input torque, is modulated to achieve smooth power-on upshifts and coasting downshifts.

Abstract: A method for controlling engagement and release of friction clutches in a multiple-ratio transmission for a hybrid electric vehicle powertrain uses electric motor torque to augment engine torque as a power-on downshift is commanded. Near the end of a downshift event, total powertrain torque is modulated or reduced to reduce torque disturbances.

Abstract: A method for inhibiting stalling of an engine of a hybrid electric vehicle. The method includes determining whether the engine is running, determining whether a gear ratio of a power transfer unit is selected, starting a timer, and implementing a stall mitigation strategy. The stall mitigation strategy is terminated when a predetermined period of time has elapsed.

Abstract: A method for controlling a wheel drive system of a hybrid electric vehicle when starting a power source. The hybrid electric vehicle includes first and second power sources, a motor, and a power transfer unit adapted to drive a vehicle wheel. The method includes determining whether the first power source is to be started, determining whether a level of torque requested by a vehicle operator is greater than a threshold value, maintaining a current gear ratio if the threshold value is exceeded, and providing a target level of torque to the power transfer unit.

Abstract: An automotive vehicle driveline includes an internal combustion engine for transmitting input torque to a hydraulically-actuated input clutch, and having a throttle controlled by a displaceable accelerator pedal. A transmission produces multiple gear ratios between the clutch and an output. A method for controlling operation of the clutch includes determining a magnitude of clutch pressure that would produce a torque capacity of the input clutch equal to the current magnitude of input torque; if no transient condition occurs, pressurizing the clutch at a magnitude of pressure that produces a predetermined slip of the input clutch at the current magnitude of input torque; and if a transient condition occurs, holding and/or reducing the determined input clutch pressure such that slip occurs at the input clutch.
