摘要： In a hydraulic actuator control device, a changing tendency of responsiveness of a hydraulic actuator to changes in the oil control valve (OCV) drive duty of a virtual OCV is stored as model control characteristics. The ratio of an actual OCV dead zone width to a virtual OCV dead zone width is calculated as an OCV variation correction coefficient. A basic control amount is calculated based on a deviation between an operating amount and a target operating amount of the hydraulic actuator. An actual OCV in-dead-zone control amount is obtained by correcting a virtual OCV in-dead-zone control amount with the OCV variation correction coefficient, and an actual OCV out-of-dead-zone control amount is calculated based on a virtual OCV out-of-dead-zone control amount. The actual OCV control amount is the sum of the actual OCV in-dead-zone control amount and the actual OCV out-of-dead-zone control amount.

摘要： An engine control apparatus which performs torque-down control during shifting is structured so as to determine a retard rate from an MBT ignition timing which will achieve a target torque-down rate, and determine a target ignition timing based on that retard rate. The retard rate that achieves a given torque-down rate changes substantially linearly with respect to the MBT ignition timing, so that change is easy to predict. Accordingly, the structure and configuring and the like of the engine control apparatus are simplified.
