Abstract
Controls for improved drivability of a vehicle equipped with start/stop logic are disclosed. One exemplary embodiment is a method comprising stopping an internal combustion engine of the vehicle to achieve a target speed profile during slowing of the engine to reduce noise, vibration and harshness, and/or to achieve a target engine stop position. Another embodiment is a method for selecting between a nominal re-start mode and a delayed re-start mode where launching of the vehicle after a stop is delayed relative to the nominal start mode in response to a vehicle input.
