    Abstract: When a restart of an engine is performed due to the requirement of a vehicle state unintended by a driver, a creep force which is initially generated is suppressed to a small value so that a vehicle is prevented from moving off. When automatic stop conditions are satisfied, the engine 1 stops, and when restart conditions are satisfied, a starting motor 2 is started so as to restart an engine 1. A condition for engine restart unintended by the driver is determined, and during a predetermined time when the engine restarts unintended by the driver, a smaller creep drive force is generated than when the engine restarts which is intended by the driver. During this predetermined time, only the motor 2 is rotated without starting the engine, and the creep force is suppressed low.

    Abstract: An automatic transmission has a transmission control section performing a control so that a transmission ratio defined as input rpm/output rpm of the automatic transmission becomes a target transmission ratio, a slip control section slip-controlling a frictional engagement element in the automatic transmission so that the input rpm becomes a value obtained by multiplying the output rpm by the target transmission ratio also adding a predetermined slip revolution speed; and an abnormality judgment section judging abnormality in the automatic transmission. When the slip-control is not in progress, if an actual transmission ratio is out of a predetermined range of the target transmission ratio, the abnormality judgment section judges that abnormality occurs. When the slip-control is in progress, if a value obtained by correcting the actual transmission ratio on the basis of the slip revolution speed is out of the predetermined range, the abnormality judgment section judges that abnormality occurs.

    Abstract: In a vehicle which has an automatic stop/restart device of the engine 1, the engine 1 is started rapidly only in cases where a quick start of the engine 1 is required such as when the vehicle is stationary on a rising slope, or cuts across the opposite lane for a left turn. For this purpose, excitation of an motor 2 is performed before startup of the motor 2 for restarting the engine 1 quickly. When automatic stop conditions are satisfied, the engine 1 stops, and when restart conditions are satisfied, the motor 2 is started to restart the engine 1. When the vehicle is on a rising slope and it is required to start the vehicle quickly, the motor 2 is energized first before the motor 2 is started. Also, when it is determined that the vehicle must start rapidly such as when the vehicle is trying to cut across the opposite lane for a left turn, the motor 2 is excited before it starts. In this way, when it is desired to start, the vehicle quickly, a rapid restart of the engine 1 and therefore rapid start of the vehicle is possible.
