Description

[Detailed Description of the Invention] Overview In recent years, failure diagnosis devices that determine the operating status or diagnostic information of the entire vehicle have been in widespread use. When the necessity of repair or replacement of parts is diagnosed through the failure diagnosis, the necessity is stored in the memory using a written code, analyzed at a replacement or repair service shop, and repair work is performed. In the present invention, when the need arises, the failure data is displayed and information on facilities where the repair work is possible is displayed to the driver. In this way, it is possible for the driver to speed up the repair response to the vehicle in which the abnormal condition is detected.

Further, when the necessity is diagnosed, the failure data is automatically transmitted to the facility side 1'. The facility that has received the data analyzes the data, transmits information about the vehicle I\nearest facility, and prepares for the vehicle's visit. In this way, it is possible to speed up the facility's ability to repair a vehicle in which the abnormal condition has been detected. These speed-ups can shorten the time it takes to complete repairs and replacements, and also
This also helps prevent the spread of failures to other locations, that is, the cumulative number of failures.

Industrial Application Field The present invention determines the operating status or diagnostic information of the entire vehicle, and when the vehicle is abnormal, it displays and stores the abnormal condition, and the vehicle is brought to a repair shop. This invention relates to a failure detection method to improve maintenance performance.

2. Description of the Related Art In recent years, vehicles have been equipped with a fault diagnosis function that determines the operating status or diagnostic information of the entire vehicle.

A certain processing circuit from a microcomputer or the like that functions as the fault diagnosis sends and receives signals from time to time to various control devices such as an EFI (electronic fuel injection device) and a constant speed cruise control device to carry out the various controls described above. It diagnoses whether the device is operating normally. It also inputs signals from various sensors such as a liquid level sensor and an oil pressure sensor to diagnose whether the amount of gasoline, oil, etc. is adequate.

If it is determined through the above diagnosis that the control device needs to be repaired or parts replaced, it will be displayed using an image display using a CRT (cathode ray tube) or liquid crystal display, or an audio display using a speaker. The operating condition of the vehicle is abnormal. In other words, it is not acceptable for the vehicle to continue driving as it is. 2. 1. Warn the moss riders. Furthermore, the failure data for repair or replacement is stored in a memory provided in the processing circuit using a predetermined storage code. After that, when the driver takes the vehicle to a repair shop or parts store, the stored code is read out from the memory and analyzed to determine the location of the failure for repair and replacement.
It determines which parts are damaged and takes appropriate action. In this way, the failure diagnosis IIIi function improves and speeds up maintenance such as troubleshooting and parts replacement.

Problems to be Solved by the Invention Conventionally, the only data that is warned to the passenger in the above-mentioned failure diagnosis ltli function is failure data indicating failure location j←replacement location. Therefore, the operator who has confirmed the warning will immediately search for a facility such as a repair shop or parts store that can repair or replace the part. In particular, urgent matters such as gasoline replenishment and EFI failure are required. Conventionally, after receiving the warning, the driver has to check the map or search for the nearest facility while driving. The above-mentioned warning is a sudden event for the driver, and there are cases where the response to the above-mentioned search I\ is not performed promptly. In particular, if you are working in an unfamiliar area, it will take a lot of time, and as a result, failures will spread to other parts and control devices, and abnormal conditions will accumulate. An object of the invention is to provide a failure detection method that can speed up the repair of the driver's vehicle J\ when the necessity of repair or replacement is determined.

Furthermore, when the vehicle is brought to a facility as a result of this search, the facility reads the memory code stored in the memory of the processing circuit and uses a manual analysis program to
Otherwise, it is analyzed by an analysis system at the head office such as an automobile company's base station connected via a data line, the abnormality is determined, and repairs or replacements are carried out. Therefore, the memory code indicating the failure data is available to the facility from the time the vehicle is brought into the facility, and it takes a lot of time to complete the repair. In particular, in case 1, where the faulty part or parts to be replaced are determined based on multiple inspections, there may be cases where the facility to which the equipment is brought in is too inexperienced to repair the part, or the parts to be replaced are not in stock. Occasions can also occur.

Therefore, it takes a lot of time to complete the repair or replacement, and the response of the vehicle 8 to the installation side is not done quickly.

Therefore, another object of the present invention is to provide a failure detection method that can shorten the time required to complete repairs or replacements, and speed up the facility's ability to repair vehicles. Our goal is to provide the following.

Means for Solving the Problems The present invention determines the operating state of a vehicle, and when a failure or a part replacement time is detected, displays failure data indicating the failure or part replacement time. At the same time, the failure data is stored in the first storage stage, and facility data indicating a plurality of facilities that can be repaired or parts replaced based on the failure data is stored in advance in the second storage means.
