<P>PROBLEM TO BE SOLVED: To provide a control unit for a hybrid vehicle for improving convergence responsiveness to a target stroke when performing flow rate control of a friction clutch, and improving transmission torque accuracy in a transient state of changing an actual stroke toward the target stroke. <P>SOLUTION: An FR hybrid vehicle has, in a drive system, an engine Eng, a first clutch CL1, and a motor/generator MG, and includes a first clutch control unit 5 performing the flow rate control to bring the actual stroke that is an operation amount of a hydraulic actuator 14 into line with the target stroke in performing fastening/release control of the first clutch CL1. In the FR hybrid vehicle, a clutch control means (Fig.5) estimates a steady-state deviation characteristic between the target stroke and the actual stroke from a stroke-release force characteristic, tunes the steady-state deviation characteristic such that a steady-state deviation becomes zero at a reference point of the target stroke that is a control reference, and corrects the target stroke based on the tuned steady-state deviation characteristic in performing clutch control wherein the target stroke from the reference point changes. <P>COPYRIGHT: (C)2010,JPO&INPIT |
