摘要： A hybrid powertrain includes an engine having a crankshaft, and a hybrid transmission having an input member, an output member, and at least one motor/generator operable to provide or receive torque. A damper connects the crankshaft with the input member. A bi-directional rotational position sensing system operatively connects with either the crankshaft or an input side of the damper, and is configured to sense the rotational position and direction of the crankshaft, and provide a position signal indicative thereof. At least one controller is configured to receive the position signal and to provide a torque command to the motor/generator based at least in part on the position signal. The torque command is operable to cause the motor/generator to substantially cancel an expected engine torque pulse associated with the sensed rotational position during starting of the engine with the damper open. A method for controlling the hybrid powertrain is provided.

摘要： A system for an engine includes an edge detection module and a correlation calibration module. The edge detection module (i) detects edges of a camshaft of the engine using a camshaft position sensor, and (ii) detects edges of a crankshaft of the engine using a crankshaft position sensor. The correlation calibration module calibrates a correlation between the crankshaft and the camshaft based on the detected edges of the crankshaft and the camshaft, respectively.

摘要： A method of correlating a rotational position of a crankshaft to a rotational position of a camshaft includes determining a stretch value of a timing connection, which drivingly couples the crankshaft and the camshaft, and calculating a crankshaft to camshaft rotational position value indicative of the rotational position of the crankshaft with respect to the rotational position of the camshaft. The crankshaft to camshaft rotational position value is compensated based on the stretch value to provide a compensated crankshaft to camshaft rotational position value and whether the rotational position of the crankshaft correlates to the rotational position of the camshaft is determined based on the compensated crankshaft to camshaft rotational position value.
