Document Type and Number:
WIPO Patent Application WO/2002/081888
Kind Code:
A1
Abstract:
A controller of a fuel-advanced type multiple cylinder direct-injection internal combustion engine capable of providing an air volume control means excellent in responsiveness and convergence, comprising a means for calculating a target throttle opening based on the operating conditions, the target throttle opening calculation means further comprising a first calculation means for obtaining the target throttle opening by a feedback control based on the operating conditions including an intake air volume, a second calculation means for obtaining the target throttle opening by a feedforward control based on the operating conditions, and a third calculation means for obtaining the target throttle opening based on both values of the target throttle opening obtained by the first calculation means and the second calculation means.
