Abstract
In a transmission control system for a vehicle, in a torque return period at the time of up-shifting of a transmission, an engine torque and a clutch torque are increased in parallel. A target engine torque value and a target clutch torque value are set such that the clutch torque changes at a value higher than the engine torque. The target clutch torque value is set such that a difference between an amount of energy generated in a clutch and an amount of energy generated in an engine substantially coincides with an amount of energy required to reduce the rotation speed of the engine to a target rotation speed.
