A detection method for detecting a blocked or unlocked state of a parking brake member including a bistable linear electromagnet connected both to a power supply component arranged to generate a control voltage and to a current sensor arranged to measure the control current. The detection method includes controlling the power supply component to generate a test voltage across terminals of a coil and thus generate a test current flowing in the coil, the test voltage having an amplitude less than a predetermined voltage threshold so that a test magnetic field generated by the test current does not move a shuttle, acquiring measurements of the test current as produced by the current sensor, analyzing the measurements of the test current, and detecting the blocked or unlocked state of the parking brake member based on the analysis.
