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 5):
The friction brake system as claimed in  claim 4 , wherein the estimation calculation section of the braking friction coefficient estimator is configured such that, when an absolute value of a calculation result of a determinant of a full rank matrix including the brake pressing force in the plurality of independent linear expressions is less than a predetermined value, influence of a friction coefficient estimation result derived by using the determinant, on a finally derived friction coefficient estimation result, is made smaller than influence of another friction coefficient estimation result derived when the absolute value is greater than the predetermined value, or the friction coefficient estimation result derived by using the determinant is excluded from estimation results.
