Abstract
A rear-wheel drive system includes motors for generating driving force to drive a vehicle, hydraulic brakes on power transmission lines between the motors and rear wheels switching a motors side and a wheels side to a connected state or a disconnected state, an ECU controlling the motors and the brakes and a one-way clutch in parallel with the hydraulic brakes on the transmission line configured to be engaged when a forward rotational power on the motors side is inputted into the wheels side and disengaged when a backward rotational power on the motors side is inputted into the wheels side and vice versa. The ECU causes the hydraulic brakes to be applied so as to put the motors side and the wheels side in the connected state when the forward rotational power on the motors side is inputted into the wheels side.
