Abstract
There are prevented shocks that will occur when a switchover speed changing is made to transfer from one speed changing, in the midst of that speed changing, to another speed changing when the input and output speed ratio 'Gratio', which serves a control parameter, is not accurately detected. For that purpose, there is used a flag FGFAIL for setting '1' when the input and output speed ratio 'Gratio', at the time of non-speed changing, does not lie within a predetermined range based on the gear ratio of the speed stage that is being established at that time. A switchover speed changing in which switching to another speed changing is made during a speed changing is prohibited when FGFAIL=1.
