Abstract

PURPOSE: To reduce the shock while to improve the power performance and the fuel consumption, by performing the lock-up particularly when the slip rate of a torque converter is low during the travel under lock-up release state.
CONSTITUTION: The interfaces of the lock-up and the lock-up release are determined to be the lock-up interfaces N2, N3 N4 and the lock-up release interfaces F2, F3, F4 as the car speed corresponding with each throttle opening, and stored to ROM. The lock-up and lock-up release interfaces to be compared are selected by the current speed step and the lock-up state to write the car speed corresponding with the throttle opening into LUPAT in RAM memory and compared with current car speed to perform the lock-up control.
