Abstract: An oil control valve assembly for an engine is provided that has a control valve with a valve body, and a manifold that defines a control passage in fluid communication with a valve lift switching component and an exhaust passage for exhausting fluid from the valve. The control valve is controllable to selectively direct fluid from a supply source to the control passage to actuate the valve lift switching component. An elongated tubular member is positioned adjacent the engine component and is operatively connected to the exhaust passage such that fluid flows from the exhaust passage to the elongated tubular member and through the elongated tubular member onto the engine component.

Abstract: An apparatus is provided that includes an engine, an exhaust system, and a thermoelectric generator (TEG) operatively connected to the exhaust system and configured to allow exhaust gas flow therethrough. A first radiator is operatively connected to the engine. An openable and closable engine valve is configured to open to permit coolant to circulate through the engine and the first radiator when coolant temperature is greater than a predetermined minimum coolant temperature. A first and a second valve are controllable to route cooling fluid from the TEG to the engine through coolant passages under a first set of operating conditions to establish a first cooling circuit, and from the TEG to a second radiator through at least some other coolant passages under a second set of operating conditions to establish a second cooling circuit.

Abstract: A vehicle includes a traction motor, a transmission, a speed encoder for the motor, and a control system. The control system compensates for angular wobble in an encoder signal. The control system receives, via a hybrid control processor (HCP), the encoder signal from the speed encoder, and determines a set of wobble characteristics of the encoder signal below a threshold motor speed. The control system also calculates a wobble-compensated speed value via the HCP using the wobble characteristics, and uses the wobble-compensated speed value as at least part of the input signals when controlling the motor. A lookup table tabulates a learned wobble value relative to the angular position value, and a learned wobble value is subtracted from a current angular wobble value to generate an error-adjusted wobble value. A method compensates for wobble in the encoder signal using the above control system.

Abstract: A door of a vehicle is moveable between a closed position, an intermediate position and an open position. When moving between the closed position and the intermediate position, a first vertical edge of the door moves parallel with a body of the vehicle and a second rearward vertical edge of the door moves laterally away from the body of the vehicle. A striker assembly for the door is attached to the body and includes a striker that is moveable between a first position and a second position. A latch mechanism selectively engages the striker when the door is disposed in or moving between the closed position and the intermediate position, with the striker moving with the first edge of the door between the closed position and the intermediate position to prevent lateral movement of the door.
