AUTOMATIC TRANSMISSION SYSTEM FOR VEHICLES

摘要

In an electronically controlled automatic transmission system including a gear transmission (5) and a clutch (4), in which a target gear position is determined in accordance with map data for gear shift control, it is discriminated whether or not the vehicle is in accelerating condition and necessary control for shifting up the transmission to the target gear position is carried out only when the vehicle is not in the accelerating state. Thus, when the driver presses hard on an accelerating member (15) to accelerate the vehicle, a series operations for shifting up is not carried out, whereby the transmission is kept in its present gear position. The operation for shifting up can be carried out after the completion of the acceleration of the vehicle.
