Abstract: <P>PROBLEM TO BE SOLVED: To highly accurately control exhaust gas recirculation rate by calculating exact learning value based on the output value of the air intake sensor and the output value of the atmosphere sensor when stopping the internal combustion engine and obtaining an exact air intake pressure based on an output value of an air intake pressure sensor when controlling the operation of an internal combustion engine.  <P>SOLUTION: The learning value Pihc is calculated from the difference between the output value Pim of the air intake pressure sensor and the output value Patm of the atmospheric pressure sensor when an output stabilizing condition (S108, S110, S112) of the air intake pressure sensor directly after stopping of a diesel engine holds (S114). When the output stabilizing condition is established, the actual air intake pressure in the air intake system is stabilized into the atmospheric pressure, and is not influenced by the delay owing to a hard filter so that the exact learning value Pihc is obtained. When operating a diesel engine at the learning value Pihc, the output value Pim of the air intake pressure sensor is corrected to obtain accurate suction pressure data to enable the control of an EGR ratio with high precision.  <P>COPYRIGHT: (C)2005,JPO&NCIPI
