  • Publication number: 20200362960
    Abstract: A transmission control device is used in an automatic transmission device including a transmission gear having friction coupling portions that are changed between a coupled state and an uncoupled state, and configuring transmission stages corresponding to a combination of the coupled state and the uncoupled state, and a hydraulic control device. The device includes: a determination unit determining a change in the transmission stage; and an output unit setting a target value of the hydraulic pressure, and outputting the target value to the hydraulic control device. In a case where one transmission stage is changed to another, the output unit increases the target value to a first value for a first friction coupling portion in the uncoupled state in the one transmission stage, thereafter, to a second value smaller than the first value and maintaining the uncoupled state, and thereafter, to a third value greater than the second value.
