CDA CDACYLINDER DE-ACTIVATION CONTROL METHOD AND SYSTEM APPLIED BY THE METHOD

摘要

The present invention relates to a CDA switching control method and a CDA system to which the control method is applied, the method comprising the steps of: obtaining an operating state signal of the vehicle; determining whether the CDA mode operation region of the CDA apparatus Preparing a CDA mode of operation of the CDA device in response to a CDA mode operation of the CDA device; And controlling the vehicle operation according to a normal region operation map of the CDA apparatus when the CDA mode operation region is not the CDA mode operation region of the CDA apparatus, When the mode is switched from the inactive mode to the active mode, the first exhaust valve remains in the operating state after the combustion is performed in the selected cylinder, and the remaining exhaust valves and the intake valves are switched to the inoperative state, And the exhaust anti-trap control in which all of the exhaust gas is discharged in a state in which it is opened is not accepted.
