記載の車輌用自動変速機の制御装置。[Claims for Utility Model Registration] 1. The valve operating state of at least one of the intake valve and the exhaust valve can be switched to at least two states: a low-speed switching state suitable for a low-speed range and a high-speed switching state suitable for a high-speed range. A control device for an automatic transmission used in a vehicle equipped with an internal combustion engine having a valve actuation mechanism that changes gears based on basic gear shifting characteristics determined by engine load and either vehicle speed or engine rotational speed. A control device for an automatic transmission for a vehicle, characterized in that part or all of the shift characteristics are changed in a specific operating state in which the valve operating mechanism is maintained in a low speed switching state. 2. The control device for an automatic transmission for a vehicle according to claim 1, wherein the changed shift characteristic performs a shift at a relatively higher vehicle speed or higher engine rotational speed than the basic shift characteristic. 3. The specific operating state is an operating state in which the temperature of any one of the engine cooling water temperature, engine oil temperature, cylinder block temperature, and transmission oil temperature, which changes in temperature depending on the engine operating state, is a predetermined temperature. Claim 1 or 2 characterized by
A control device for an automatic transmission for a vehicle as described above.
