Drift and dispersion correcting method for vehicle, involves comparing two air flows, and calculating correction to be subjected to first air flow that is measured by using air flow measuring device
The method involves measuring air flow by using an air flow measuring device (13). Another air flow is estimated by using an air-fuel mixture richness measurement and injected fuel quantity estimation, where the estimation is obtained by estimating indicated average torque of a cylinder. The air flows are compared. Correction to be subjected to the former airflow and measured using the device is calculated.
