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.
