To provide a brake force estimation device and a brake force estimation method capable of improving accuracy of brake force of a friction brake device and controlling a friction brake and a regenerative brake for optimizing the use of the regenerative brake in a manner that optimizes a ratio of the friction brake force to the regenerative brake force and thereby improving electricity consumption.SOLUTION: A brake force estimation device is for a vehicle comprising a steering actuator steering a steering wheel. The brake force estimation device has brake force estimation means which estimates brake force generated while braking on the basis of steering reaction force on the steering actuator and a distance between the steering wheel and a rotation shaft center of the steering actuator.SELECTED DRAWING: Figure 3
