Abstract

When an engine torque trace is set during acceleration or deceleration, the ratio of increase or decrease in the engine torque per unit time is restricted so that when the engine torque generated during acceleration or deceleration approaches an engine torque (balance torque) at which the engine is oriented upright with respect to the engine mount, the engine torque stays near the balance torque for a prescribed time.
