CONTROL APPARATUS AND CONTROL METHOD FOR AUTOMATIC TRANSMISSION
摘要:
An ECU executes a program including the steps of: starting monitoring the turbine revolution speed and the output shaft revolution speed when a direct shift is started; performing complete disengagement control on a disengagement element; lowering control pressure of a disengagement element to preliminarily fixed control pressure; starting engagement control on an engagement element when a set time period Ts passes; performing complete disengagement control on the disengagement element when a set time period Ts passes; and starting the engagement control on an engagement element when turbine revolution speed NT is equal to or larger than (the synchronous revolution speed of a gear after a shift—a set value Ns).
