Abstract

Provided is a power transmission control device capable of reliably performing engagement between an engagement member and a target engagement member, by operating the engagement member to slide by an actuator having an elastic member deformed by transmitting a load received by the engagement member. An actuator has an elastic member, and a control unit calculates the differential rotation between an engagement member and target engagement members on the basis of the detected rotation speeds of a first rotation shaft and a second rotation shaft, and makes differential rotation coincide with a predetermined differential rotation by adjusting the rotation speed of power sources. After the differential rotation coincides with the predetermined differential rotation, in establishing the engagement, the predetermined differential rotation sets the differential rotation on the basis of a natural frequency generated in conjunction between the actuator and the engagement member by the elastic member.
