A fluid pressure brake unit generates a friction braking force by supplying an operating fluid to a wheel cylinder provided to each wheel of a vehicle so as to press a brake pad against the wheel. A regenerative brake unit generates a regenerative braking force by electric power regeneration to a motor that drives the wheel. A battery collects electric power from the motor. A low-temperature determination unit determines that the temperature of the battery is low when the temperature of the battery is below a predetermined temperature range. A battery temperature increasing unit generates, when the temperature of the battery is determined to be low, a braking force to the vehicle by at least either a fluid pressure brake unit or a regenerative brake unit during acceleration of the vehicle by the motor or the engine.
