Title:
ENGINE CONTROL DEVICE
Document Type and Number:
WIPO Patent Application WO/2011/096383
Kind Code:
A1
Abstract:
The disclosed engine control device sets a first target engine RPM in response to a command value commanded by a command means, and then sets a second target engine RPM having the same or lower RPM than the first target engine RPM on the basis of the first target engine RPM. If the first target engine RPM is lowered, the second target engine RPM is set so as to be the same or lower than the first target engine RPM, and the point drop which reduces the first target engine RPM to the second target engine RPM is set so to be reduced. When the first target engine RPM is at least the same or lower than the engine RPM at the maximum torque point, the point drop is set to zero.
