Document Type and Number:
Japanese Patent JP2002187462
Kind Code:
A
Abstract:

To provide a speed change controlling device for an automatic transmission for a vehicle capable of relieving shock accompanied by speed change at the time of speed change of a kick down skip which is generated by reacceleration during a sudden stop of the vehicle and a method therefor.

When 3→1 speed change conditions of the kick down skip are satisfied by a tip-in operation during 4→3 speed change before stopping and the 3→1 speed change of the kick down skip is conducted immediately after the 4→3 speed change completion before stopping, a torque reducing starting point of an engine and a torque reducing duration time thereof are determined according to a deceleration rate of a vehicle at the time of 4→3 speed change before the stopping. The torque of the engine is reduced according to the determined torque reducing starting point of an engine and torque reducing duration time thereof.
