Claim 5:
6. A method for detecting malfunctions of an electro-actuated brake apparatus according to claim 1, wherein said step of performing the error validation check comprises the further steps of:
comparing the error signal with an error threshold which is constant over time;
generating a first stepped count signal comprising:
a first stepped signal portion having an amplitude increasing over time from a first instant, in which an amplitude of the error signal switches from a value which is lower than the error threshold to a value which is higher than the error threshold,
a second stepped signal portion having an amplitude decreasing over time from a second instant, in which the amplitude of the error signal switches from a value which is higher than the error threshold to a value which is lower than the error threshold,
comparing the amplitude of the first stepped count signal with the amplitude of a constant maximum count signal having predetermined amplitude for calculating a stay time of the error beyond the threshold;
generating the aforesaid information on the operating state of the electro-actuated brake caliper when the amplitude of the first stepped count signal equals the amplitude of the constant maximum count signal.
