Abstract
When an automatic transmission is shifted from neutral to a forward gear, an ECU calculates the appropriate target gear. If the target gear speed is the second forward gear or higher, a target command pressure of a first engagement element is immediately increased to a maximum pressure regardless of an input torque, and a target command pressure of a second engagement element is gradually increased in accordance with the input torque.
