Title:
CONTROLLER OF THROTTLE VALVE
Document Type and Number:
Japanese Patent JP2018162686
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To adjust opening of a throttle valve with high accuracy.SOLUTION: An ECU 52 is a controller configured to control a throttle valve 36 that regulates an amount of air suctioned into an engine 12. The ECU causes calculation means of repeatedly calculating charging density of the engine 12 to repeatedly calculate the charging density to adjust opening of the throttle valve 36 so that the calculated charging density goes below a threshold. In calculation of charging efficiency, a plurality of parameters including a suctioned air temperature is referred to, thereby enhancing adjustment accuracy for opening of the throttle valve 36.SELECTED DRAWING: Figure 1
