Abstract

An injection amount learning device for an internal combustion engine is suitably utilized to execute an injection amount learning in the internal combustion engine. Concretely, a first learning portion performs the injection amount learning by injecting a very small amount of fuel from a fuel injection valve to a cylinder of the internal combustion engine during deceleration of the vehicle. A control portion performs a control so that the torque produced by the fuel injection from the fuel injection valve is cancelled out at the time of the injection amount learning. For example, the speed change ratio of a continuously variable transmission is shifted so that the torque caused by the fuel injection is cancelled out by the brake torque of the internal combustion engine.
