Abstract
Methods and systems are provided for adjusting a throttle during deceleration fuel shut off (DFSO). In one example, a method may comprise controlling a position of a throttle in an air inlet of an engine propelling a vehicle, in relation to vehicle operator commands, and during a deceleration fuel shut off mode, increasing opening of said throttle independently of said operator commands when speed of said vehicle is or is expected to fall below a desired speed or desired speed trajectory.
