A method for determining a capacitance value of a super-capacitor of an electro-mechanical braking system of at least one vehicle, wherein said super-capacitor is arranged to store an amount of electrical energy sufficient to cause the electro-mechanical braking system to perform at least one emergency braking action;
- wherein said method includes the steps of:
- a) measuring a first voltage value at terminals of said super-capacitor;
- b) if said first voltage value is greater than a predetermined minimum voltage value, performing a charge or discharge action of said super-capacitor for a measurement time period, wherein said charge or discharge action is arranged to make said terminals of said super-capacitor assume a second voltage value greater than or equal to said minimum voltage value;
- c) determining a voltage variation at the terminals of said super-capacitor during said measurement time period;
- d) determining a voltage variation rate on the basis of the voltage variation at the terminals of said super-capacitor determined in step c) and a duration of time of said measurement time period;
- e) measuring a current value flowing in one of said terminals of said super-capacitor, at a measurement instant of said measurement time period;
- f) calculating the capacitance value of said super-capacitor by means of the ratio between said current value measured at said measurement instant and said voltage variation rate.
