Patent ID: 7349787

Claim:
A method of servo-control in a vehicle brake system including at least one electric brake having at least one actuator comprising a pusher that faces friction elements and is driven by an electric motor to apply a force selectively against the friction elements in response to a braking setpoint, the method making use of a plurality of relationships between various operating parameters of the actuator including a relationship between a pusher position and a corresponding force applied by the pusher to the friction elements, the method comprising: adjusting said particular relationship between said pusher position and said corresponding force, wherein said adjustment comprises: operating the brake under operating conditions in which the force applied by the pusher against the friction elements depends essentially on a power supply current flowing through the electric motor; in at least one position of the pusher, measuring the power supply current of the electric motor and deducing a corresponding force therefrom; and from said at least one position and said corresponding force, deducing a correction for the relationship between pusher position and corresponding force.
