Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
231 words
Integral protection system for vehicles whose purpose is to prevent the functioning of the engine, as well as to store data concerning maintenance of the vehicle, for which purpose it is essentially characterized because it has an intelligent card (chip card) (1) reader/writer terminal (2) included in the vehicle (20) and which is connected to a central processing unit (3) which in turn is connected to a volatile RAM memory (5), to a ROM memory (4) and to an entry/output circuit (6) to which a plurality of sensors (7) are connected configuring the breakless ignition and other functions of the vehicle (20); it being provided that the functioning program of the system included in the ROM memory (4) is incomplete (10); and with the particular feature that the intelligent card (1) includes the program portion (9) which completes the program portion included in the ROM memory (4), so that upon connecting said intelligent card (1) to the reader/writer writer terminal (2), prior introduction of a personal identification number (PIN), the program portion (9) included on the intelligent card (1) is transferred to the RAM memory (5) (11) with which the central processing unit (3) carries out the function of the breakless ignition and therefore the starting of the vehicle upon turning the key, erasing the program portion (11) included in the RAM memory (4) upon disconnecting the system, which remains protected.
Claim 2
Dependent Claim
108 words
Integral protection system for vehicles, according to claim 1, characterized because the intelligent card (1) is capable of being connected to a terminal (21) placed in a service shop (25) and remains controlled by a microprocessor (22), for the introduction of the different repair and maintenance data on said intelligent card (1), storing the "historic" data of the vehicle; it being provided that said terminals (21) placed in the service shops (25) are capable of being connected to a data processing center (24) through public or private communications networks (23), making it possible to elaborate statistics, warranty control and a control of the functioning of the different vehicles.
Claim 3
Dependent Claim
32 words
Integral protection system for vehicles, according to the above claims, characterized because the transfer of the program portion (9) from the intelligent card (1) to the RAM memory is done by crytographing.
Claim 4
Dependent Claim
49 words
Integral protection system for vehicles, according to claim 1, characterized because the reader/writer terminal (2) placed in the vehicle (20) includes the central processing unit, the ROM memory and the RAM memory in a single integrated circuit (14), in such a way that said reader/writer terminal (2) is inviolable.
Claim 5
Dependent Claim
55 words
Integral protection system for vehicles, according to the above claims, characterized because the personal identification number is capable of validating the intelligent card (1) for a certain period of time, it also being provided that it is capable of permitting the functioning of the engine for a certain period of time, after which it stops.
Claim 6
Dependent Claim
49 words
Integral protection system for vehicles, according to the above claims, characterized because it is capable of being connected to an electronic device such as for example a radio-cassette player, radiotelephone, for which purpose the latter includes an identification and entry/output circuit (26) which controls the functions of the device.
