Patent ID: 7370471

Claim:
An internal combustion engine controller, comprising target torque computation means for computing target torque based on the demand torque of an internal combustion engine such as the operation of an accelerator, means of computing a target throttle angle based on the target torque, and torque assist control means for assisting torque based on the state of the target torque and the operation state of the internal combustion engine, wherein the torque assist control means carries out torque assist control by increasing the quantity of fuel when a torque increase is demanded; wherein the operation state of the internal combustion engine is the uniform charge stoichiometric combustion state of the internal combustion engine having a three-way catalyst; and a fuel correction quantity computation means comprises fuel correction permission judging means which judges whether fuel correction is permitted or not based on the state of the target torque, the operation state of an external system and an estimated adsorption quantity of oxygen in a catalyst.
