A control system and a control method for an internal combustion engine employs an electronic control unit (ECU) in the internal combustion engine to control an output torque of the engine. The ECU anticipates that a driver will make an engine output torque change request based on an operation of an automatic transmission performed by the driver, a brake pedal operation performed by the driver, a vehicle speed detected by a vehicle speed sensor and other information, and changes in advance an amount of engine intake air, a throttle valve opening, an engine speed and other engine operating parameters that determine the engine output according to the engine output change request made by the driver. This allows even an engine operating parameter that is slow to change to be changed to a value close to that after the engine output torque has been changed. This in turn allows the engine output torque to be changed within a shorter period of time in accordance with the engine output change request made by the driver, contributing to a better response.
