Throttle control apparatus of internal combustion engine and throttle control method
 In a throttle control apparatus of an internal combustion engine, when the driver operates an accelerator so as to cause a motor vehicle to proceed to a steady-state running mode, a target throttle opening amount is no longer controlled to a throttle opening amount that depends upon an operated amount of the accelerator. Instead, the throttle opening amount is controlled to a value that provides a steady-state required torque. In this manner, the vehicle is immediately brought into a desired steady-state running mode, without requiring the driver to repeatedly operate the accelerator since the accelerator operation is not directly reflected by the throttle opening amount. Thus, the driver need not frequently repeat accelerator operations when the vehicle enters a steady-state running mode, thus assuring improved driveability.
