トマチツクトランスミツシヨン車の制御装置。 In an automatic transmission vehicle, the vehicle speed signal, range selector signal, and accelerator pedal opening signal are input to the controller, and the gear change of the transmission is automatically performed via a hydraulic clutch based on these signals. In addition to inputting the fuel rack position signal, the magnitude of the running load during automatic gear shifting is detected, and when the running load is relatively large, the rise of the oil pressure supplied to the hydraulic clutch is made abrupt, and when the running load is relatively small, the hydraulic pressure supplied to the hydraulic clutch is increased suddenly. A control device for an automatic transmission vehicle, characterized by comprising a controller that moderates the rise of hydraulic pressure supplied to a hydraulic clutch.
