An automatic engine stop and restart system includes an engine, a starting motor, a transmission, a vehicle operating condition sensor and a controller. The controller monitors the vehicle operating condition to produce an automatic engine restart request signal during an automatic engine stop operation, calculates a target engine speed for the automatic engine restart operation, and drives the motor in accordance with the target speed to perform the automatic engine restart operation in response to the engine restart request signal. During the automatic engine restart operation, the transmission is held in a drive state or in a non-drive state invariably.
