Abstract

Method (100) for estimating a brake factor parameter (BFP), the brake factor parameter (BFP) being defined as a ratio of a braking torque (BT) over a braking pressure, the braking torque (BT) being applied on a wheel of a vehicle by a braking wheel sub-system (BWSS) of a braking system (BS) of the vehicle, the braking pressure being applied by the braking wheel sub-system (BWSS) to achieve the braking torque (BT) on the wheel of the vehicle, the method comprising the following steps controlled by a braking system control unit: - collecting (101) input parameters (T, V, NL)); - estimating (102) the brake factor parameter (BFP) as a function of the at least one input parameter (T, V, NL), an output of the step of estimating being an open loop estimation (OLE1, OLE2) of the brake factor parameter (BFP).
