20090063004 | REVERSE ENGINE ROTATION DETECTION SYSTEM - A method of determining reverse engine rotation includes calculating a ratio of on time to off time of a camshaft position signal during camshaft rotation, determining whether a predetermined camshaft state has been entered based on said ratio, comparing the most recently determined camshaft state with a predetermined camshaft state pattern for forward engine rotation and determining a engine rotation direction based on said comparison. | 03-05-2009 |
20090216420 | ENGINE MOVEMENT DETECTION SYSTEMS AND METHODS - A control system for an internal combustion engine is provided. The control system includes an engine movement module that selects from N engine rotation modes based on camshaft movement and crankshaft movement, where N is an integer greater than two, and where at least one of the N rotation modes is an assisted spinning mode. A diagnostic module enables one or more engine diagnostic modes based on the selected engine rotation mode. | 08-27-2009 |
20090299586 | METHOD TO AUTOSTART AN INTERNAL COMBUSTION ENGINE IN A HYBRID POWERTRAIN SYSTEM - Internal combustion engine autostarting includes selecting from among several autostart processes in accordance with desired input torque from the engine to the transmission, cranking the engine, and fueling the engine during the engine cranking based upon the selected engine autostart process. | 12-03-2009 |
20140358400 | SYSTEM AND METHOD FOR CONTROLLING A POWERTRAIN SYSTEM TO PERFORM EXHAUST BRAKING - A system according to the principles of the present disclosure includes an exhaust braking enabling module, a driver torque module, and an engine actuator control module. The exhaust braking enabling module selectively enables exhaust braking based on driver input and independent of an accelerator pedal position. The driver torque module selectively determines a driver torque request based on a powertrain braking torque capacity when exhaust braking is enabled. The engine actuator control module controls fuel delivery to cylinders of an engine and a vane position of a turbocharger based on the driver torque request. | 12-04-2014 |
