Abstract
A driving force transmission apparatus includes a linkage mechanism that is able to carry out switchover between a connected state where a first intermediate shaft and a second intermediate shaft are connected to each other so as to be non-rotatable relative to each other to transmit torque output from an electric motor to a rear wheel, and a disconnected state where the first intermediate shaft and the second intermediate shaft are disconnected from each other. A control unit reduces the torque that is generated by the electric motor, after making a rotational speed of the first intermediate shaft higher than or equal to a rotational speed of the second intermediate shaft, and then switches the driving force transmission apparatus from the disconnected state to the connected state by controlling the linkage mechanism with the torque that is generated by the motor maintained at a reduced level.
