Slip control apparatus for motor vehicle lock-up clutch |
摘要 |
<p>An apparatus for controlling a lock-up clutch (32) between pump and turbine impellers (18, 22) in a fluid-filled power transmitting device (12) such as a torque converter of a motor vehicle, such that a slip control device (196) controls the actual slip speed of the lock-up clutch so as to coincide with a transient target slip speed, the apparatus including a device (198) for calculating a final target slip speed of the lock-up clutch which assures a maximum fuel economy of the vehicle during a steady-state running, a device (200) for setting, as an initial value of the transient target slip speed, a difference between the speeds of the pump and turbine impellers immediately before an operation of the slip control device is initiated, and a device (202) for reducing the transient target slip speed toward the final target slip speed at a rate which decreases as the transient target slip speed approaches the final target slip speed.</p> |
