Abstract: A control device and method controls a vehicle having an internal combustion engine connected to an automatic transmission via a torque converter with a lockup device. The torque of the internal combustion engine is limited the by a torque limit value based on a speed difference between an input rotational speed and an output rotational speed of the torque converter during acceleration in a non-lockup state. The torque-limiting of the internal combustion engine is prohibited torque-limiting upon a prescribed condition being met. The prescribed condition is met by a heating request, during hill climbing/towing, during travel at high vehicle speeds, when the accelerator pedal opening angle exceeds or is equal to a prescribed opening angle, when the torque limit value is greater than a target torque, in a range other than a D range, or in a mode other than normal mode.

Abstract: A control method is provided for an internal combustion engine which includes a turbocharger, and which is connected to a stepped automatic transmission. The control method includes judging whether or not an upshift of the automatic transmission is performed; performing a first torque down control by an ignition timing retard of the internal combustion engine during the upshift; judging whether or not a predicted torque estimated from a driving condition of the internal combustion engine is greater than a target torque at an end of the upshift; and performing a second torque down control by the ignition timing retard of the internal combustion engine when the predicted torque is greater than the target torque.
