Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicle password input device for externally inputting a password to set a control system to an ID information registration permission state in order to register ID information in a control system for controlling operation of a vehicle. About.

[0002]

2. Description of the Related Art In recent years, in order to enhance the antitheft property of a vehicle, a system has been adopted in which an engine is started only when ID information stored in a key and ID information set in a vehicle-mounted electronic system match. However, when the in-vehicle electronic system is replaced or the key is lost, it is necessary to re-register the ID information provided in the in-vehicle electronic system.
An external tester is used as a tool to re-register the ID information. At the time of registration, a password known only to the vehicle owner is input to the external tester, and the password is sent from the external tester to the vehicle-mounted electronic system. The system compares the received password with a password stored in advance in the on-vehicle electronic system, and registers the key ID only when the password matches with the password, thereby enhancing security.

[0003]

Generally, since re-registration of ID information is performed by a dealer, it is necessary for an operator to obtain a password from a vehicle owner. If the user forgets the password or forgets the password, the subsequent work cannot be performed. Also, if a password is given to an operator other than the vehicle owner, the original antitheft property of the present system may be lost.

[0004] The present invention has been made in view of the above,
It is an object of the present invention to provide a vehicular password input device capable of inputting a password via a telephone line to improve anti-theft property and improve ID information registration efficiency.

[0005]

To achieve the above object, according to the present invention, a password is set to set a control system mounted on a vehicle and controlling the operation of the vehicle to an ID information registration permission state.

Determining means for comparing the password with the password stored in the storage means to determine whether the two passwords match; and when the determining means determines that the two passwords match, the control system transmits the ID information to the control system. Setting means for setting the registration permission state.

[0007] Further, the present invention according to claim 3 is based on claim 2.
In the invention described, a connection means to which a tester is connected;
When the tester is connected via the connection means and the control system is set to the ID information registration permission state, the ID information transmitted from the tester to register the ID information in the control system is transmitted. The present invention has an ID information receiving means for receiving the received ID information and supplying the received ID information to the control system.

According to a fourth aspect of the present invention, a password is controlled via an external tester connected from the outside of the vehicle to set a control system for controlling the operation of the vehicle in an ID information registration permission state. A vehicle password input device for inputting to a system, wherein the external tester is connected to a telephone line, transmits vehicle identification information for identifying a vehicle transmitted from the telephone line, and a password set in the control system. Receiving means for receiving, storage means for storing the vehicle identification information and the password received by the receiving means in association with each other, and receiving the vehicle identification information transmitted from the vehicle password input device and corresponding to the vehicle identification information A password to be transmitted from the storage means, and transmitting the read password to a vehicle password input device. Means, and ID information registration control means for controlling a control system to register ID information when notified of the ID information registration permission state from the vehicle password input device, wherein the vehicle password input device comprises: Storage means for storing vehicle identification information for specifying a vehicle and a password set for the control system; vehicle identification information transmission means for transmitting the vehicle identification information stored in the storage means to the external tester; Receiving a password transmitted from the external tester, comparing the password with a password stored in the storage means,
Determining means for determining whether the two passwords match, and setting means for setting the control system to an ID information registration permission state when the determining means determines that the two passwords match; ID set by setting means
The gist of the present invention is to include a notification unit for notifying the external tester of the information registration permission state.

[0009]

According to the first aspect of the present invention, a password transmitted from a telephone line is received, this password is compared with a password stored in a control system in advance, and only when both passwords match. Control system I
Since the D information registration permission state is set, the vehicle owner does not need to give the password to anyone, so that there is no loss of theft, and the dealer operator needs to ask the vehicle owner for the password. Since there is no ID information registration process, the ID information registration process can be performed smoothly.

According to the second aspect of the present invention, a password transmitted from a telephone line is received, and the password is compared with a password stored in advance. Is set to the ID information registration permission state, even if the password is forgotten, the password can be received via the telephone line, the ID information registration process can be performed smoothly, and the password can be stored in the vehicle. There is no need to teach workers etc.
The anti-theft property of the vehicle can be improved.

Further, according to the present invention, when the tester is connected and the control system is set to the ID information registration permission state, the I transmitted from the tester is transmitted.
Since the D information is received and the ID information is supplied to the control system to register the ID information, the ID information can be accurately registered in the control system.

According to the present invention, the external tester transmits the password received from the telephone line to the vehicle password input device, and the vehicle password input device compares the password with a previously stored password. If the two passwords match, the control system is set to the ID information registration permitted state, and the external tester sets the control system to
In the D information registration permission state, the ID information is registered, so that the vehicle owner does not need to give the password to anyone, so that the anti-theft property is not lost, and the dealer's worker writes the password into the vehicle. Since there is no need to ask the owner, ID information registration processing can be performed smoothly.
