Braking system for at least one vehicle, system and process for the calibration of a braking system of at least one vehicle, and vehicle

A system for calibrating a braking system of a vehicle wherein said braking system comprises a braking element arranged to receive an actuation signal and apply a corresponding braking force (F) to at least one wheel of said vehicle or at least one disc of said vehicle;

• wherein the braking force (F) applied by the braking means is a function of a value of said actuation signal;
• the braking system also comprising of a control circuit arranged to:
• receive a test braking request indicative of an expected instantaneous deceleration value;
• determine the value of said actuation signal to apply the braking force (F) such that the vehicle would be decelerated according to said expected instantaneous deceleration value;
• actuate said braking element according to the determined value of the actuation signal;
• wherein said control circuit is arranged to determine the value of said actuation signal as a function of at least a predetermined expected friction value between said braking element, a test mass value of at least one vehicle, and said expected instantaneous deceleration;
• wherein said predetermined expected friction value between said braking element and at least one said wheel or at least one said disc is arranged to be stored in a storage media;
• said system for calibrating a braking system comprising calibration circuit arranged to be associated with said braking system of at least one vehicle (V) and to:
• receive the value of the actuation signal determined by the control circuit;
• said calibration circuit further being arranged to:
• a) determine a real instantaneous vehicle deceleration value during actuation of said braking means according to said value of the actuation signal;
• b) determine a real friction value between said braking element and at least one said wheel or at least one said disc as a function of at least said real instantaneous deceleration value, the test mass value of that vehicle, and said actuation signal value;
• c) replace the predetermined expected friction value stored in the storage media with the determined real friction value.
