摘要： PROBLEM TO BE SOLVED: To improve security by suppressing illegal communication between an electronic key and a vehicle using a relay machine in an electronic key system. SOLUTION: A communicable area is limited to a second communication area 42 while including the position of the electronic key 10 discriminated by the arrival direction of a response signal. When radio wave is relayed by the relay machine 101, a receiving antenna 102 and a transmitting antenna 107 must be installed in the second communication area 42. Therefore, both antennas 102, 107 are positioned close to each other, and jamming occurs in the relay machine 101. When the receiving antenna 102 and the transmitting antenna 107 are installed at positions apart from each other, for example, the receiving antenna 102 comes out of the second communication area 42, and the receiving antenna cannot receive a request signal transmitted to the second communication area 42. Consequently, illegal communication through the relay machine 101 can be suppressed, and the security of the electronic key system can be improved. COPYRIGHT: (C)2011,JPO&INPIT

摘要： PROBLEM TO BE SOLVED: To provide an electronic key system of a vehicle, which is effective for the prevention of a forcible entry of a third person into a vehicle interior. SOLUTION: In this electronic key system of the vehicle, a distance measurement signal Scd is given and received between an in-vehicle device 10 and a portable machine 20; it is determined through the giving and receiving of the signal that the portable machine 20 is positioned in a communicable area A; a request signal Srs and a response signal Sas are given and received; the authentication of the portable machine 20 is established through giving and receiving of the signals; and a vehicle door is unlocked on the basis of the determination and the establishment of the authentication. In this case, after a re-request signal Srr is transmitted after the transmission of the request signal Srs from the in-vehicle device 10, the portable machine 20 specifies a mode of a reply of the portable machine 20 to the re-request signal Srr. The vehicle door is unlocked under additional condition that the portable machine 20 replies to the re-request signal Srr on the basis of the specified reply mode. COPYRIGHT: (C)2011,JPO&INPIT

摘要： A secret key registration system which registers a secret key in a portable key device and vehicle. A first transformation equation is stored in a writer and the vehicle. A second transformation equation is stored in the portable key device and the vehicle. The writer transmits a registration code to the portable key device and generates intermediate data with the first transformation equation of the writer. The intermediate data is transmitted to the portable key device, which generates the secret key from the intermediate data with the second transformation equation. The portable key device transmits the registration code to the vehicle. The vehicle generates intermediate data from the registration code with the first transformation equation of the vehicle, and then generates the secret key from the intermediate data with the second transformation equation.

摘要： PROBLEM TO BE SOLVED: To provide a vehicle control system which improves convenience while securing a user's operability in a situation in which radio communication cannot be established between a vehicle and a portable machine. SOLUTION: This vehicle control system performs electronic authentication of the portable machines 20 and 30 by establishing the radio communication between an on-vehicle unit 10 and the portable machines 20 and 30, and unlocks a vehicle door on the basis of the electronic authentication. In this case, mechanical keys 26 and 36 different in a key code are annexed to the portable machines 20 and 30, respectively. In addition, the in-vehicle unit 10 is provided with a lock device 40 with a changeable unlocking code. When key code information is transmitted to the in-vehicle unit 10 from the portable machine 30, the in-vehicle unit 10 changes the unlocking code of the lock device 40 on the basis of the transmitted key code information.

摘要： PROBLEM TO BE SOLVED: To provide a system for registering a private key, which prevents the occurrence of theft of the private key, and to provide a method for registering the private key. SOLUTION: In order to register the private key 16 in both of a vehicle 1 and an electronic key 2, first, an on-vehicle equipment center key 22 is written in the vehicle 1 by a writing unit 18, and an electronic key center key 23 is written in the electronic key 2. Then, the private key 16 produced in a center 20 is encoded by the on-vehicle equipment center key 22 taken in previously and converted into an on-vehicle equipment registration code Ccr, and this is delivered to the vehicle 1. Moreover, the same private key 16 is encoded by the electronic key center key 23 taken in previously and converted into an electronic key registration code Cdk, and this is delivered to the electronic key 2. Then, the registration codes Ccr, Cdk are decoded respectively in the vehicle 1 and the electronic key 2, and the decoded data are registered respectively as the private key 16.
