Abstract
An engine torque control apparatus for controlling the output torque of an engine () connected to a transmission () in a vehicle has a temperature sensor () for detecting the temperature of oil used by the transmission (), and a controller () for limiting the output torque of the engine to an engine torque limit or less. The controller () functions to compare the oil temperature with a specific temperature, to set the engine torque limit to a first limiting value when the oil temperature is equal to or less than the specific temperature, and to increase the engine torque limit at a predetermined increase rate when the oil temperature exceeds the specific temperature.
