Security arrangement for motor vehicle equipped with a programmed hands-free monitoring system

1. Field of the Invention A security arrangement for motor vehicle equipped with a programmed monitoring system () and with at least one specific system () to which the monitoring system transmits commands. The arrangement comprises hard-wired logic () mounted between a control facility () and the specific system, as is the monitoring system. This logic makes it possible to block a command (OV) transmitted by the monitoring system to the specific system, when this command corresponds to that which is obtained in respect of an instruction (C) received by the control facility and when such an instruction has not been received from the control facility by the hard-wired logic. The arrangement is intended to be fitted to a vehicle comprising a programmed monitoring system, such as a "hands-free" monitoring system, and one or more specific systems, for example an electrical anti-theft system or electrical supply monitoring system.
