摘要:
A control device for a vehicular automatic transmission which can realize a shifting with quickened response with suppressing a turbine blow-up during the shifting is provided. When a response in hydraulic pressure control by a hydraulic pressure control circuit 42 fails to satisfy a preset predetermined determining criterion, a shifting response is prevented from improving, in comparison to a case where the determining criterion is satisfied. Under a relatively low response of the hydraulic pressure control by the hydraulic pressure control circuit 42 due to air mixture to working oil, a control to inhibit a high-response shifting or the like is performed, so that a turbine blow-up caused by a delayed response of hydraulic pressure can be prevented. Thus, the control device for the vehicular automatic transmission can be provided, which can realize the shifting with quickened response, with suppressing the turbine blow-up during the shifting.
