ABSTRACT:
In a vehicle automatic transmission system in which the target gear position of gear-type transmission is determined by a map calculation based on predetermined map data in response to at least a condition signal indicative of vehicle speed, the system has a detector for detecting whether or not the transmission is being operated for changing gears and the target gear position is fixed during the operation for changing gears, whereby the gear change operation can be attained in stable condition regardless of the change in the vehicle speed during the gear change operation.
