Abstract: An engine and a second power generating device transmit power through a transmission to a driveline to a wheel. A control module determines a regenerative braking axle torque capacity and a regenerative braking torque. Power output from the second power generating device is controlled based upon a regenerative braking axle torque request. A brake control module determines a total braking torque request and generates the regenerative braking axle torque request based upon the total braking torque request, the regenerative braking axle torque capacity, and the regenerative braking torque. The brake control module controls a friction brake.

Abstract: A separator may include a body, an inlet portion, and an outlet conduit. The body may include a conical interior surface defining a conical cavity. The cavity may have a first outlet at a tip of the body. The inlet portion may be connected to the body and may include an outer surface, a cylindrical inner surface, and a first inlet passage extending between the outer surface and the inner surface. The inner surface may be defined by the longitudinal axis. The first inlet passage may be positioned relative to the inner surface such that a fluid flow through the first inlet passage is generally tangent to the inner surface. The outlet conduit may extend through the inlet portion and into the cavity. The outlet conduit may include a second inlet passage disposed inside of the cavity and a second outlet disposed outside of the body and the inlet portion.
Abstract: A bumper assembly for a vehicle to which a towing hook member can be removably coupled includes a bumper beam having a cavity defined at least partially by a first wall and a second wall. The first and second walls are separated at a distance. Also, the bumper assembly includes a receiver having a receiver opening operable to removably couple to and removably receive the towing hook member. The receiver opening is exposed from the bumper beam, and the receiver also has a first portion and a second portion. The first portion is removably coupled to the first wall of the bumper beam, and the second portion is removably coupled to the second wall of the bumper beam.

Abstract: A method of operating a park lock mechanism in a vehicle includes determining a force acting on a vehicle park lock mechanism when the vehicle is in park, and providing an offsetting force to counteract the force on the park lock mechanism before the vehicle is shifted out of park. In doing so, harshness and noise that may be associated with shifting a vehicle out of park, especially when the vehicle is parked on an incline, can be reduced or eliminated.
Abstract: A method for controlling a vehicle's exhaust gas recirculation system. The method controls the exhaust gas recirculation system in a manner that is suitable for a pedal tip-out transition while also being optimized for normal operating situations.
Abstract: In at least one implementation, an engine oil circuit for a vehicle includes first and second oil circuits, and first and second oil pumps. The first oil circuit is communicated with at least one first engine component and the first oil pump is communicated with the first oil circuit to supply fluid flow in the first oil circuit at a first flow rate and a first pressure. The second oil circuit is communicated with at least one second engine component and may be segregated from the first oil circuit. The second oil pump is communicated with the second oil circuit to supply fluid flow in the second oil circuit at a second flow rate and a second pressure. At least one of the second flow rate or the second pressure is different than the first flow rate or the first pressure.
Abstract: A fluid-pressure indicator is provided and may include a housing having a first region and a second region. A pressure-responsive member may be disposed in the first region and may be movable between an expanded state and a compressed state. An indicator disk may be viewable through the pressure-responsive member when the pressure-responsive member is in the compressed state and may be obscured from view through the pressure-responsive member when the pressure-responsive member is in the expanded state. A diaphragm may be movable from a relaxed state to a deflected state in response to pressure within the second region exceeding a threshold pressure and may prevent fluid communication between the first region and the second region. The diaphragm may additionally cause the pressure-responsive member to move from the expanded state to the compressed state when the pressure exceeds the threshold pressure.
Abstract: An engine is mechanically coupled to a transmission device, the transmission device operative to transfer mechanical power between the engine and a second power generating device and an output member. A method for controlling the engine includes monitoring an operator demand for power, selecting a preferred engine state, determining a preferred engine torque input to the transmission device when operating in the preferred engine state based upon the operator demand for power, determining constraints on the engine torque input to the transmission device based upon a capacity of the transmission device to react the engine torque input, and commanding operation of the engine to the preferred engine state and commanding the engine torque input to the transmission device based upon the preferred engine torque input and the constraints on the engine torque input.

Abstract: An on-board diagnostic system for detecting malfunction conditions in a hydraulic valve train of a MultiAirâ„¢ engine. The system comprises a plurality of pressure sensors for generating pressure signals located in a hydraulic circuit of the hydraulic valve train; and an engine control module for performing a waveform analysis of the pressure signals to detect malfunction conditions in the hydraulic valve train. The engine control module performs a frequency and/or time delay waveform analysis.
Abstract: A vehicle compartment cover coupling that moveably couples a vehicle compartment cover to a main body of a vehicle for movement of the vehicle compartment cover between an open position and a closed position. The cover coupling includes a first member that is coupled to the main body of the vehicle. The cover coupling further includes a second member that is coupled to the vehicle compartment cover, wherein the second member is moveably coupled to the first member. The vehicle compartment cover coupling further includes a retaining coupling that is operable to engage the first and second members together during a vehicle impact condition. The retaining coupling engages the first and second members to limit movement of the compartment cover in a first predetermined direction during the vehicle impact condition.
Abstract: A method for testing the evaporative emission system of a vehicle. The method provides for testing the evaporative emission system of a vehicle having a forced induction engine. The method includes controlling a vacuum bypass valve and a purge flow control valve to create the necessary conditions to perform the testing of the evaporative emission system.

Abstract: A method and system for optimizing a weld schedule is disclosed. The weld schedule is used to control a plurality of welding apparatuses, and includes a plurality of weld sequences for control the plurality of welding apparatuses. The weld sequences each define one or more weld events. Each of the weld events defines a weld operation and a duration of the weld operation. The weld schedule is analyzed to determine if any time points in the weld schedule have two or more weld events scheduled where the aggregate current demand exceeds a maximum current threshold. If such a conflict in the weld schedule is identified, the weld schedule is modified by rescheduling a lower priority weld event. The method executes iteratively until all conflicts in the welding schedule are resolved.
Abstract: A pendulum absorber assembly for a torque converter including a first spring retainer, a second spring retainer, and a floating flange positioned between the first spring retainer and the second spring retainer. The pendulum absorber assembly also includes a drive plate affixed to the floating flange, a plurality of arcuate springs disposed between the second spring retainer and the drive plate, and a plurality of pendulum weights affixed to the second spring retainer, wherein the pendulum weights are made of tungsten alloy.
