Abstract:
Controls for improved drivability of a vehicle equipped with start/stop logic are disclosed. One exemplary embodiment is a method comprising operating a vehicle system including an internal combustion engine and a controller configured to conditionally stop and re-start the engine. The controller tracks the distance that the vehicle has traveled since the most recent vehicle stop and determines a time limit as a function of that distance. The controller further tracks the time that an engine stop request condition has been true, evaluates that time relative to the time limit, and selectably enables or disables an engine stop based upon the relationship between said time and said time limit.
