Abstract:
A control apparatus for a vehicular internal combustion engine, comprising:a) an accelerator operating variable detector for detecting an operating variable of an accelerator operated by a vehicle driver;b) a revolution speed detector for detecting a revolution speed of the engine;c) a driver demand torque calculator for calculating an engine torque demanded by the vehicle driver on the basis of the detected operating variable of the accelerator and the detected revolution speed as a driver's demand torque;d) an external demand torque calculator for calculating a correction variable for the engine torque demanded from an external load to the engine as an external demand torque;e) a relatively low response demand torque calculator for calculating a relatively low response demand torque on the basis of at least one of the driver's demand torque and the external demand torque;f) a relatively high response demand torque calculator for calculating a relatively high response demand torque on the basis of at least one of the driver's demand torque and the external demand torque;g) a first torque operator for operating at least one object to be controlled in a relatively low response characteristic so as to realize the calculated relatively low response demand torque;h) a second torque operator for operating at least one object to be controlled in a relatively high response characteristic so as to realize the calculated relatively high response demand torque.
