ABSTRACT:
The present invention concerns an anti-theft device for automotive vehicles acting on the braking circuit to lock the wheels. The device according to the invention acts on the hydraulic braking circuit of a vehicle, the circuit comprising a generator of hydraulic energy (1) or master cylinder connected by the intermediary of hydraulic conduits to hydraulic energy receiving mechanisms or brake (2), the device being characterized essentially by a second generator of hydraulic energy (3) connected to the hydraulic braking circuit below the first generator (1) and by a hydraulic circuit selector means (4) which switches the receiving mechanisms (2) either only with the first energy generator (1), or only with the second (3), this latter taking place when a surveillance circuit detects information indicative of an unauthorized use of the vehicle, which surveillance circuit in this case acts on the second generator (3) such that this latter pressurizes the brakes of the vehicle.
