摘要: Methods and systems are provided for controlling a vehicle system including an engine that is selectively deactivated during engine idle-stop conditions. One example method includes, during a first condition, engaging an engine starter, without applying a starter current, to the deactivated rotating engine after the engine speed drops below a threshold speed. The method further includes, during a second condition, engaging the starter and adjusting a starter motor switch to apply a starter braking torque to the rotating engine.

摘要: A method for improving starting of an engine that may be repeatedly stopped and started is presented. In one embodiment, the method disengages a starter in response to a first predicted combustion in a cylinder of the engine. The method may reduce one-way clutch degradation of a starter. Further, the method may reduce current consumption during engine starting.

摘要: A method for improving starting of an engine that may be repeatedly stopped and started is presented. In one embodiment, the method skips combustion in at least one cylinder, according to the engine combustion order, to control engine speed when an engine is automatically restarted. The skipped combustion event may be related to a level of IMEP when combustion in a cylinder occurs under an operating condition.
