<p>The objective of the present invention is to activate a failsafe function appropriately when an error occurs with the control device itself, even when a failsafe valve is not provided in an oil pressure control circuit. When a gear change specification value SHdir, which specifies transmission control for an automatic transmission (18), and a gear change output value Shout, which is output in accordance with that gear change specification value SHdir, do not match, a prescribed failsafe operation is implemented. Therefore, when an unnecessary frictional engagement device is engaged in the current gear range configuration of the automatic transmission (18) due to an error with an electronic control device (100), a prescribed failsafe operation is implemented and the influence of the error in the electronic control device (100) can be suppressed. Accordingly, a failsafe function can be activated appropriately when an error occurs with the control device (100) itself, even when a failsafe valve is not provided in the oil pressure control circuit (50).</p> |
