Abstract
A power transmission control device includes a first rotation shaft, a first power source to adjust rotation speed of the first rotation shaft, a second rotation shaft interlocked with an axle, a first switching mechanism to connect/disconnect switching between the first and second rotation shafts, a third rotation shaft, a second power source to adjust rotation speed of the third rotation shaft, and a second switching mechanism to connect/disconnect switching between the third rotation shaft and the second rotation shaft. At least one switching mechanism of the first switching mechanism and the second switching mechanism is a dog clutch type, and reliably and stably performs the connection switching thereof. A control stores information on a rotation phase of the first/third rotation shafts. At least one of the first/second switching mechanisms is held in a connected state, and the rotation phase is adjusted based on stored information at the connection switching.
