Abstract
An object of this invention is, with respect to a torque-demand-control type controller that subjects two kinds of actuators provided upstream and downstream in an intake passage to coordinated operations based on a requested torque for an internal combustion engine, to enable realization of a pulse-like torque change in a torque decreasing direction that is requested, for example, when performing an upshift operation in an electronically controlled automatic transmission. To achieve this object, according to a controller for an internal combustion engine of this invention, when a pulse component in a torque decreasing direction is included in a requested torque, a second requested torque that does not include the pulse component is generated. In this case, a first actuator provided on the downstream side in the intake passage is operated based on the requested torque. On the other hand, although a second actuator provided on the upstream side in the intake passage is operated based on the requested torque when there is not a valid value of the second requested torque, the second actuator is operated based on the second requested torque when there is a valid value of the second requested torque.
