Beschreibung
Zusammenfassung:	A parking brake system (1) for a motor vehicle is provided with a lever (2), which can rotate in a first and in a second rotation direction, which are opposite one another, a ratchet mechanism (6) to lock the rotation of the lever (2) in the second rotation direction, an actuator (9) to release the ratchet mechanism (6), a first transducer (T1) to detect a quantity (G1) indicative of the rotation of the lever (2) in the first rotation direction, a second transducer (T2; T3) to detect the activation of a brake pedal or of an accelerator pedal of the motor vehicle, and a control unit (12), which is coupled to the first transducer (T1) so as to extract information associated with the quantity (G1) and to the second transducer so as to receive a signal in response to the activation of the brake pedal or of the accelerator pedal; the control unit (12) is configured to compare the information with a reference value and to control the actuator (9) so as to release the ratchet mechanism (6) when it receives the signal and the information has a predetermined relation with the reference value.
