Abstract
A driving force transmission apparatus includes a linkage mechanism that is able to carry out switchover between a connected state where first and second intermediate shafts 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 and second intermediate shafts are disconnected from each other. When switching the driving force transmission apparatus from the connected state to the disconnected state, a control unit reduces the torque that is generated by the motor during a drive state where the torque output from the motor is transmitted from the first intermediate shaft to the second intermediate shaft, and switches the driving force transmission apparatus from the connected state to the disconnected state by controlling the linkage mechanism while the torque that is generated by the motor has been reduced.
