Abstract:
The friction brake system includes a braking force distributor configured to output load command values to friction brake devices for a plurality of wheels, and a friction coefficient estimation calculation section configured to estimate a friction coefficient between a brake rotor and a friction material of each friction brake device. The friction coefficient estimation calculation section includes a distribution adjustment section configured to change distribution of brake pressing force to be distributed by the braking force distributor, for estimation of the friction coefficient, and an estimation calculation section configured to estimate the friction coefficient on the basis of a relationship between deceleration of a vehicle and the load command values the distribution of which is changed.

Claim (Index 1):
A friction brake system comprising a plurality of friction brake devices provided in a vehicle, and a higher-order control unit including a braking force distributor configured to distribute target brake pressing force to each friction brake device in accordance with requested braking force, each friction brake device including: a brake actuator having a brake rotor, a friction material, and a friction material actuator configured to press the friction material against the brake rotor; and an individual brake controller configured to control output of the friction material actuator in accordance with the target brake pressing force distributed from the braking force distributor, wherein\n the friction brake system comprises a braking friction coefficient estimator configured to estimate a friction coefficient between the brake rotor and the friction material of each friction brake device, the friction coefficient being reflected by distribution of the brake pressing force by the braking force distributor.
