変速機の制御手段。 An automatic clutch in which at least one clutch element is interposed between an input element connected to an engine and an output element connected to drive wheels, and is supplied with hydraulic pressure from a hydraulic control means to generate a fastening force corresponding to the hydraulic pressure. In a transmission, battery voltage detection means detects battery voltage and outputs a low potential signal when battery voltage is below a predetermined value, and stationary state determination means detects vehicle speed and outputs a stop signal when vehicle speed is below a predetermined vehicle speed. means, a valve opening detection means for detecting the valve opening of the throttle valve and outputting an idle signal when the valve opening is less than a predetermined value, and the low potential signal, the stop signal, and the idle signal are all inputted. judgment means for outputting a drive signal when the clutch element is engaged; and a judgment means that is interposed between the hydraulic pressure control means and the clutch element, and reduces the pressure of the hydraulic pressure supplied to the clutch element when the drive signal is input to apply a fastening force to the clutch element. A control means for an automatic transmission, characterized in that it has a hydraulic pressure adjustment means for reducing.
