POWER TRANSMISSION CONTROL DEVICE

WIPO Patent Application WO/2018/124217

A1

[Problem] To shorten the time from a switching request to completion of a disengagement operation. [Solution] A control unit in a power transmission control device must be provided with a function for performing the following: switching request processing for outputting a switching request that is a request to switch from a state in which power transmission by a first speed reduction mechanism is established to a state in which power transmission by a second speed reduction mechanism is established; power transmission disabling processing in which an actuator is operated so as to disable power transmission by the first speed reduction mechanism on the basis of the switching request output as a result of the switching request processing; switching request prediction processing for predicting that a switching request will be output as a result of the switching request processing; and preliminary operation processing for operating the actuator in advance in a direction in which a switching mechanism disables power transmission by the first speed reduction mechanism while maintaining the state in which power transmission by the first speed reduction mechanism is established prior to performing the power transmission disabling processing when the switching request prediction processing predicts that a switching request will be output.
