Security arrangement for motor vehicle equipped with a programmed hands-free monitoring system
First Claim
1. A security arrangement for motor vehicle equipped with a control facility (3), with at least one specific system (2) and with a programmed monitoring system (1) which is hard-wired between said control facility and said specific system in order that said programmed monitoring system (1) can receive an instruction (C) from said control facility and transmit thereupon a command (OV) to the specific system, wherein said security arrangement comprises hard-wired logic (4) mounted between said control facility and said specific system in order to be able to receive said instruction (C), said hard-wired logic blocking said command sent by said programmed monitoring system to said specific system when said hard-wired logic has not received said instruction (C).

Abstract
A security arrangement for motor vehicle equipped with a programmed monitoring system (1) and with at least one specific system (2) to which the monitoring system transmits commands. The arrangement comprises hard-wired logic (4) mounted between a control facility (3) 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.
