| titleOfInvention | Intake Negative Pressure Prediction Method for Air-fuel Ratio Control |
| abstract | BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an intake negative pressure prediction in a method for controlling an air-fuel ratio of a vehicle. In general, in determining the optimum fuel injection amount injected into an engine, first, the intake negative pressure should be known, and when the intake negative pressure is determined, the fuel injection amount is determined by itself. Because. Accordingly, in the intake negative pressure measurement method as described above, there are a method of directly measuring with an air flow meter and a speed density measuring method of indirectly measuring intake air amount. Among them, the conventional intake negative pressure prediction method in the transient mode has a problem that the control logic structure is complicated and appropriate adjustment is difficult by compensating by dividing the compensation variable value into the TPS change value and the MAP change value.n n n Thus, the present invention is to solve the problems as described above, so that the constant acceleration and deceleration compensation is always performed by applying the variable values in the method of predicting the intake negative pressure in the transient mode as described above without dividing them into two stages. Therefore, the fuel injection amount can be accurately determined in order to precisely cope with the occurrence of various acceleration / deceleration factors in the transient mode caused by the engine load fluctuations at the intake underpressure prediction. |
