Driver's vehicle diagnostic apparatus and early warning
First Claim
1. A method for diagnosing a vehicle state by connecting a vehicle equipped with an electronic control unit with a personal computer (PC) by cable or wirelessly, and then connecting the PC to a mechanic center on the Internet, the vehicle state diagnosing method comprising the steps of:
- (a) in a first communications module connected to a communications port of the PC, checking whether a registered vehicle approaches within a local area network (LAN) zone;
(b) in the PC, driving an electronic control unit diagnosing program, if a response signal is received from the vehicle having a second communications module;
(c) in the second communications module, signal-converting diagnosis data output from the electronic control unit installed in the vehicle and storing the conversion result in a memory, and then transmitting the conversion result to the first communications module; and
(d) in the case that it is judged that the vehicle is abnormal in the result of analyzing the received diagnosis data in the PC, providing a user with a maintenance method and purchase information of parts, or in the case that a failure cannot be repaired by the user, guiding the user to make reservations with a mechanic center through the Internet.

Abstract
A method for diagnosing a vehicle state by connecting a vehicle equipped with an electronic control unit with a personal computer (PC) via a local area network (LAN) communication method, and then connecting the PC to a mechanic center on the Internet, is provided. The vehicle state diagnosing method comprising the steps of: (a) in a first communications module connected to a communications port of the PC, checking whether a registered vehicle approaches within a local area network (LAN) zone; (b) in the PC, driving an electronic control unit diagnosing program, if a response signal is received from the vehicle having a second communications module; (c) in the second communications module, signal-converting diagnosis data output from the electronic control unit installed in the vehicle and storing the conversion result in a memory, and then transmitting the conversion result to the first communications module; and (d) in the case that it is judged that the vehicle is abnormal in the result of analyzing the received diagnosis data in the PC, providing a user with a maintenance method and purchase information of parts, or in the case that a failure cannot be repaired by the user, guiding the user to make reservations with a mechanic center through the Internet. A vehicle diagnostic system of a vehicle equipped with a electronic control unit enables a user to check an abnormality of a vehicle in advance and maintain the vehicle, to thereby greatly reduce a possibility of accidents which may occur during running, and to also make reservations conveniently with a mechanic center with respect to a failure which cannot be repaired by a general user, so that the vehicle can be maintained.
