Based on whether a requisite braking torque is less than a drive torque of the driving wheel, braking force is generated for only driving wheels, or braking force is generated for driven wheels, in addition to that for the driving wheels. Thus, it is possible to maintain the creep speed to the target speed and achieve a suitable front and rear braking force distribution on downward slope roads where a gravity impellent is acting on the vehicle, as well as on flat roads and upward slope roads. The ability to achieve such a suitable front and rear braking force distribution ensures that the driven wheels will not easily lock up on a low μ road surface or the like.
