Abstract

PURPOSE: To have optimum EGR performed at all times by a method wherein a vehicle running pattern is identified from a frequency of a speed change operation to select an EGR valve operating pattern specified by each running pattern and an EGR valve is controlled according to this operating pattern.
CONSTITUTION: Respective detection signals are output during a vehicle run by a revolution speed detector 9, an engine load detector 8 and a transmission gear box operating frequency detector 10. A signal from the detector 10 is impressed together with a signal from a unit signal generator 11 to an operator 12 to calculate a transmission gear box operating frequency per unit time. An output of the operator 12 is impressed to an identifier 13, where the output is identified whether it belongs to a high load continuous running pattern or a low speed running pattern, and then the identification signal is impressed to an EGR valve operating pattern selector 14. Then, a revolution speed area and a load area specified in advance in accordance with the selected operating pattern are input to a valve controller 15, and an EGR valve 6 is controlled based on outputs of detectors 8, 9.
