Method of controlling automobile, automobile control apparatus, transmission, method of controlling transmission and vehicle system

The invention relates to a method of controlling an automobile, an automobile control apparatus, a method of controlling a transmission, a transmission, a transmission control apparatus and a vehicle system, which can reduce affection caused by unevenness among drive power sources (1) and transmission torque changing means and aging effect without using sensors. A power train control unit releases a torque from an engine (1) through an assist clutch so as to release at least a part of a transmission torque of gear trains in order to shift a meshing clutch toward a release position. During the gear release, a load is applied in a direction in which the meshing clutch is shifted toward the release position, before all part of the transmission torque of the gear train is released, and the meshing clutch is shifted to the release position when at least a part of the transmission torque of the gear trains is released.
