Method of servo-control in a braking system having electric brakes

1. A method of servo-controlling a vehicle brake system including at least one brake electric 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 relationship for transforming a setpoint for the braking to be applied by the pusher into a setpoint for the position of the pusher, the method comprising the steps of:

operating the brake in 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;

for at least one operating point, identifying a position of the pusher and the corresponding power supply current of the electric motor, and deducing a corresponding force from the measured current; and

adjusting the relationship between the position setpoint and the braking setpoint as a function of the position and the force as determined in this way;

wherein said operating conditions include imposing at least one position pause on the pusher.

2. A method according to claim 1 , in which the at least one position pause is the result of using a position setpoint including at least one pause.

3. A method according to claim 1 , in which the at least one pause results from using a position setpoint that causes the pusher to be moved in such a manner that the power supply current of the electric motor reaches a maximum available current level.

4. A method according to claim 1 , wherein the adjustment step is implemented at least once per utilization cycle of the vehicle.
