  • Patent number: 11118677
    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.

  • Publication number: 20210270016
    Abstract: Provided is a work machine capable of notifying that maintenance is necessary due to continuation of clogging in a cooling device or decrease in cooling performance. A wheel loader 1 including a radiator 31 and an oil cooler 32 comprises a controller 5, 5A configured to determine a clogging continuation state of the radiator 31 or the oil cooler 32. The controller 5, 5A determines whether clogging is occurring in the radiator 31 or the oil cooler 32 based on outside air temperature AW and cooling water temperature CW or hydraulic oil temperature HW, determines whether the clogging continues based on a clogging occurrence ratio R1, R2 while an engine 30 is operating, and outputs a notification command signal for providing the alarm buzzer 61 and the user management system 62 with a command to notify that maintenance is necessary when it is determined that the clogging continues.
