Claim 3

System as claimed in claim 1 characterized in that the servo-con trol actuating section (4) includes members (K1, 9, 10) suited to prevent the engine from starting when accesses are locked.

Claim 4

System as claimed in claims 1 and 2 characterized in that the servo-control actuating section (4) includes members suited to prevent accesses lock when the engine is running.

Claim 5

System as claimed in anyone of previous claims characterized in that the servo-control actuating section (4) includes members (K1, 8) suited to connect the warning and antitheft installation simulta neously with accesses locking, and to disconnect it on releasing.

Claim 6

System as claimed in anyone of previous claims characterized in that it includes means suited to send signals, of any kind, to confirm reception of control signal by the servo-control actuating sec tion (4), and that said section includes members (X2, 11) to control said signaling means.

Claim 7

System as claimed in claim 5 characterized in that the motor-vehicle is already equipped with said signaling means for other purpo ses.

Claim 8

System as claimed in claim 5 characterized in that the signaling means control members (K2, 11) are composed of a distance transmitting device installed on the motor-vehicle and of a receiving device included in the portable device, which actuates then the signaling means also included in the portable device.

Claim 9

System as claimed in claim 7 characterized in that the distance transmitting device installed on the motor-vehicle can be actuated, besides by the servo-control actuating section (4), also by the war ning and antitheft installation when warning starts, therefore to transmit a Warning signal which can also be different from the signal indicating received control.

Claim 10

System as claimed in anyone of the previous claims characterized in that the portable device includes two members for control by the driver, one for accesses lock and warning and antitheft installation connection, and the other one for release and disconnection, and that therefore the encoding section and the decoding one include re spectively two encoders and two decoders, and the servo-control actuating section (4) is double and includes namely two identical sec tions, one of which to lock accesses and to connect the warning and antitheft installation and the other one for release and disconnection.

Claim 11

System as claimed in claim 9 characterized in that the servo-control actuating section (4) is composed of two identical electronic circuits including each at least electronic components and elec tronic components units suited for and so inserted as to obtain res pectively supply voltage stabilizing and filtering, transistors and other components protection, safety against repeated controls due to bounce of the control member by the driver, safety against protracted actuation of said member, supply timing of servo-control actuating relay, the accesses lock circuit including an even non electronic servo-control actuating and warning and antitheft instal lation connecting relay, an even non electronic engine start lock relay, and electronic components suited for and so inserted as to prevent servo-control actuating relay supply when the engine is run ning, and the other circuit for release of accesses including an even non electronic servo-control actuating and warning and antitheft installation disconnecting relay, supply of all said circuits being ensured by the motor-vehicle battery or by a special power source.

Claim 12

System as claimed in anyone of the first eight claims characterized in that the portable device includes only one member for control by the driver, and therefore the encoding and decoding sections respectively include only one encoder and one decoder, and the servo-control actuating section is not double, but includes at least one memory device (K1) which ensures alternate forwarding of an accesses lock and warning and antitheft installation connection control signal (8) and a release and disconnection control signal (7).

Claim 13

System as claimed in claim 11 characterized in that the servo-control actuating section (4) is composed of an electronic circuit (4a) including up the memory device (K1) at least electronic components and electronic components units suited for and so inserted as to obtain supply voltage stabilizing (CR2) and filtering (C2), tran sistors and other components protection (CR1, CR4, CR6, CR7, CR8, CR9, CR10), safety (CR5) against repeated controls due to bounce of the member of control by the driver, safety (C2-Q2) against protrac ted actuation of said member, memory device (K1) supply timing (CR4 -R4-C2-Q2-R7-Q3), cut off (Q5-CR7-C3-CR8-C4-R12-R13) of said supply when engine is running; of the memory device (K1) which controls the accesses lock electronic circuit (8-8a) and simultaneously warning and antitheft installation connection (8) and engine start lock (9-10), and the accesses release electronic circuit (7-7a) and simultaneously warning and antitheft installation disconnection (8) and engine start release (9-10); and of said two identical electronic circuits down the memory device (K1), which actuate the servo-control respectively for lock and release of accesses, each one of said circuits including at least electronic components and electronic components units suited for and so inserted as to obtain respec tively supply voltage stabilizing (CR11) and filtering (C5), transistors and other components protection (CR12, CR16, CR18, CR20, CR13, CR17, CR19), supply timing (CR14-B24-C6-Q10, CR15-R25-C7-Q11) of servo-control actuating relay (K3, K4); supply (14, 18) of all said circuits being ensured by the motor-vehicle battery or by a special power source.
