A method for controlling engine torque in a vehicle during a default throttle condition includes determining whether a throttle of the engine is in a default throttle condition, determining whether the engine is producing more torque than desired if the throttle of the engine is in the default throttle condition, and applying an accessory load to the engine if the engine is producing more torque than desired in the default throttle condition.

Provided is an internal combustion engine control system capable of simultaneously and suitably carrying out the will of a driver to accelerate and modifications to the throttle opening degree characteristics. An internal combustion engine control system is provided with an accelerator pedal operation amount sensor for detecting the accelerator pedal operation amount, a storage unit for storing multiple different throttle opening degree characteristics of an engine relative to the accelerator pedal operation amount, a switch for selecting the throttle opening degree characteristic pertaining to a plus sports mode in response to an operation, and an engine control unit for controlling the throttle opening degree of the engine on the basis of the selected throttle opening degree characteristic and the detected accelerator pedal operation amount.
