Patent ID: 7476178

Claim:
A device for preventing over-rotation of an engine with an automatic transmission, comprising: a rotation velocity sensor for detecting a rotation velocity of the engine; and a controller receiving input from the rotation velocity sensor, the controller including: an engine torque control part operable to control a torque of the engine based on a driver request for driving force; an over-rotation preventing part operable to suppress the torque controlled by the engine torque control part based on the rotation velocity and to prevent over-rotation of the engine; an over-rotation prevention releasing part operable to release suppression of the torque by the over-rotation preventing part based on the rotation velocity lowered due to upshifting of the automatic transmission; and an engine torque increasing rate regulating part operable to regulate an increasing rate of the torque when the suppression of the torque is released and the torque is increased due to the over-rotation prevention releasing part.
