Abstract
Official abstract text for this publication.
The present invention is a proposal relating to cooperative manipulation of an actuator which actively changes a supercharging pressure and a throttle in the case of application of torque demand control to an internal combustion engine with a supercharger. A control device provided by the present invention separately determines a target air quantity for manipulation of the throttle, and a target air quantity for manipulation of the actuator. In more detail, driver required torque which is included in required torque is converted into an air quantity in accordance with a predetermined conversion rule, and the air quantity which is obtained by the conversion is determined by calculation as a reference target air quantity. The reference target air quantity is used as a target air quantity for throttle manipulation, and is also used as a target air quantity for actuator manipulation at a normal time. When a change occurs to the required torque, and the change cannot be realized under the reference target air quantity, a correction target air quantity capable of realizing the change is determined by calculation, and is used as the target air quantity for throttle manipulation.
First claim
Opening claim text (preview).
The invention claimed is: 1. A control device for an internal combustion engine with a supercharger having an actuator which actively changes a supercharging pressure, the control device controlling an air quantity which the internal combustion engine takes in a cylinder by cooperative manipulation of a throttle and the actuator based on required torque for the internal combustion engine, the control device comprising: target air quantity determining means that separately determin…
