VEHICLE CONTROL DEVICE, CLUTCH SLIP CONTROL DEVICE, AND IDLING SPEED CONTROL DEVICE

摘要

PURPOSE:To make a slip control of a lock-up clutch stably and with good follow-up performance despite changing operating characteristics resulting from a change in the operation point. CONSTITUTION:A characteristic compensation part CC is added to an object to be controlled, and the object viewed from. an operation amount command value calculating part OC as a controller is made an enlarged object to be controlled OB. Because a change in the characteristics of the enlarged object EOB is compensated by a characteristic compensation part CC with a shift of the operation point, the enlarged object EOB viewed from the operating amount command value calculation part OC as a controller is working at the design point at all times. The characteristic compensation part CC compensates the dislocated of the gain and phase depending upon the frequency through a filter computation and compensates the standing gain dislocation through multiplication of a constant.
