In order to provide a brake controller that can generate as much regenerative braking force as possible in a vehicle and effectively improve fuel consumption even during times of reduced tire grip force such as when the vehicle is turning, a brake controller is provided with a friction brake device (B), a regenerative brake device (A), a requested braking force calculation unit (27), a vehicle motion control unit (30) for distributing requested braking force (Fd) to the other non-regenerative braking-side left or right wheel of either left and right front wheels (Wfl, Wfr) or left and right rear wheels (Wrl, Wrr), a maximum braking force calculation unit (29) for calculating the maximum braking force (Fmax) of the vehicle wheels (Wfl, Wfr, Wrl, Wrr), and a braking force control unit (31) for calculating regenerative braking force (Fc) generated in the regenerative braking-side left and right wheels within a range that does not exceed the lesser value of the maximum braking force (Fmax) between the regenerative braking-side left and right wheels, on the basis of the requested braking force (Fd) and the distribution of braking force to the non-regenerative braking-side left or right wheel.
