Automatic transmission control device and control method |
摘要 |
An automatic transmission control device controls multiple speed changes in which shifting from first speed to second speed occurs during shifting from second speed to first speed. The control device includes a shift lever position sensor, an ECT_ECU, and an AT linear solenoid. The ECT_ECU includes a circuit that detects multiple speed changes; a circuit that controls the AT linear solenoid such that an engagement pressure of an engaged first speed engine brake friction element sweeps down when multiple speed changes are detected; and a circuit that commands a shift to second speed once a predetermined time has passed since the detection of multiple speed changes assuming that the engagement pressure of the first speed engine brake friction element has sufficiently swept down.
