載の自動変速機の制御装置。[Scope of Claim for Utility Model Registration] 1. Between the manual valve and a friction engagement element to which hydraulic pressure is not supplied when the manual valve is in the non-traveling position and to which hydraulic pressure is supplied when the manual valve is in the traveling position. An electrically actuated throttling means capable of controlling the flow of oil in the direction of supplying hydraulic pressure to at least the frictional engagement element is provided in the oil passage between the two,
The throttle means is operated by an electric signal from a control unit, and the control unit has a lacing detection means that detects that the engine is rotating at high speed when the manual valve is in the non-driving position, and a lacing detection means that detects that the engine is rotating at high speed when the manual valve is in the non-driving position. A control device for an automatic transmission, comprising: throttling effect reducing means for outputting a signal that reduces the throttling effect of the throttling means more than in other cases when high speed rotation of the engine is detected. 2. The racing detection means is configured to determine a racing state when the vehicle speed is 0 or close to 0 and the engine rotation speed is above a predetermined value or when the throttle opening is above a predetermined value. automatic transmission control device.
