The control mode for a braking force is switched from the stationary-vehicle control mode to the normal control mode, if it is determined that the demanded braking force becomes smaller than the command value for the stationary-vehicle braking force.

Abstract: A brake control apparatus is provided that distributes an engine braking torque Tbe to the front and rear wheels in accordance with an ideal braking torque distribution to suppress and prevent the tendency for one of either the front or rear wheels to lock when the engine braking torque operates.

When the friction state between the wheels and the road surface is not in the low friction state, the generator attached to the engine is operated as a motor that supplements driving of the engine to reduce the engine braking torque of the engine.
