MAINTENANCE MANAGEMENT METHOD OF VEHICLE}

The present invention relates to a maintenance management method of a vehicle.

Normally, as a way to manage the maintenance history of the vehicle, if the mechanic of a specific company visits or receives maintenance from a specific company, the maintenance history is managed on the server. Was performed.

In this case, since the driver of the vehicle must be continuously maintained with a specific company in order to receive a history of maintenance and replacement of consumables. No data can be linked.

On the other hand, in order to display the inspection and replacement cycle of the consumable parts of the vehicle in consideration of the engine usage conditions, as a reminder for regular replacement of consumables, the actual driving conditions such as the actual engine speed are combined with the maintenance manual data that is only the existing mileage. The driver was informed of the replacement cycle considered.

In such a case, it was good to consider the driving conditions in a complex manner, but after the exchange, the exchange device was notified to the display device to inform the next exchange period.

Drivers who aren't interested in cars don't want to do this, which is very annoying.

On the other hand, in the case of a system equipped with a self-diagnosis controller in the vehicle and sending out the details of the failure wirelessly, it is very good to visit the relevant company and perform necessary maintenance when the details of the vehicle are transmitted wirelessly like the system. In order to configure a wireless network, a lot of operating costs are involved, so there is a problem that the usage fee is steadily entered.

An object of the present invention is to provide a maintenance management method for a vehicle that can automatically manage the maintenance history by detecting the removal and replacement cycle of each consumable part periodically while driving the vehicle.

In order to achieve the above object, the present invention provides a vehicle maintenance management method, by replacing the vehicle maintenance detection means for detecting that the vehicle maintenance, and the component removal detection means for detecting the removal of each component parts replacement cycle Setting a reference mileage for each part by using a maintenance management system for automatic recording of notification and replacement status, notification of failure sites, and maintenance history management, and performing replacement recommendation and warning control operations according to the mileage; Notify when the parts are replaced, and when the parts are removed during maintenance using the maintenance detection means, the parts removal detection means detects it and compares it with the mileage to record the maintenance history by checking or replacing. And performing a control operation relating to sensing and recording.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. While many specific details, such as the following description and the annexed drawings, are shown to provide a more general understanding of the invention, these specific details are illustrated for the purpose of explanation of the invention and are not meant to limit the invention thereto. And a detailed description of known functions and configurations that may unnecessarily obscure the subject matter of the present invention will be omitted.

An embodiment of the present invention relates to a maintenance management method of a vehicle, and informs when the consumables are replaced, and detects when the consumables are removed during the maintenance by means of detecting the maintenance, and checks or replaces the mileage by comparing with the mileage. The maintenance history is automatically recorded.

Self-recording or wireless transmission of managed maintenance history enables maintenance history management independent of the workshop.

The maintenance management system automatically notifies and replaces consumable parts replacement cycles that require regular replacement, and notifies failure sites and maintains maintenance history.

Means to detect that the vehicle is under maintenance

In order to determine whether the vehicle is under maintenance, whether the engine is started or the hood is opened is detected by signals from the engine control unit ECU and the ETAS.

As an auxiliary means for determining that the vehicle is under maintenance, the amount of depression detection of the suspension may detect whether the vehicle is lifted by the lift.

To determine whether it is a proper consumable replacement or a simple check, the distance traveled is signaled by a trip computer.

Means to detect removal of each part

Detect direct detection or removal of covers.

For example, simple contact sensors, or non-contact sensors using magnets, can be set manually if the detection is not possible.

Means to replace or check when detecting removal of parts

Set the standard mileage for each part and store it in the maintenance management system.

After removal over the standard distance, record as an exchange if removed and record as a check if it is not.

By connecting the above means to manage the replacement history of consumables, inform the user of the failure site, and input the maintenance status to manage the maintenance history.

Each part informs the driver that a replacement is necessary when the replacement reference distance is reached, and displays a warning about the need for replacement when reaching the reference distance twice.

A recording system that detects that the vehicle is under maintenance and removes each consumable is described.

Engine oil, oil filter, air filter change management system

Installation of engine oil filter, engine oil drain bolt and air filter removal detection means.

When detecting that maintenance is in progress, each consumable removal detection unit is activated.

If the oil filter is removed when the mileage is over 3000 km (adjustable), it is regarded as a removal for replacement and recorded as a replacement in the maintenance management system.

The removal of the air filter and the oil drain bolt is also the same, and if it is less than 3000 km, it is removed for inspection and recorded as an inspection in the maintenance system.

Air Conditioning Antibacterial Filter Exchange Management System

If it detects maintenance, the antibacterial filter removal detection means is activated.

If the antibacterial filter is removed when the mileage is over 20000 km (adjustable), it is determined that the antibacterial filter is removed and recorded as an exchange in the maintenance management system.

If you remove the car under mileage, record it as inspection.

Transmission oil

If it detects maintenance, it activates the transmission oil level sensing means.

If the mileage exceeds 40000 km (adjustable) and the transmission oil decreases and then increases, it is determined that the oil is replaced and recorded as a replacement in the maintenance management system.

If the transmission oil level is still under normal during maintenance (or driving), the transmission oil is judged to be low and the warning lamp lights up and the maintenance management system is reported as insufficient.

Spark plugs, plug cables

If it detects maintenance, the spark plug and plug cable removal detection means are activated.

If the removal detection is possible, it works the same as the other parts above, and if the location of the removal detection sensor, such as a spark plug or plug cable, is unsuitable for the environment, it can be recorded manually in the maintenance management system.

Brake Pads, Timing Belts, Fuel Filters

The brake pad may be directly installed with a detachment detecting sensor or a sensor for detecting a cylinder detachment that must be removed for removing the brake pad.

The timing belt can not detect whether the belt is removed directly, it can be replaced by detecting the removal of the belt cover.

After that, the replacement and inspection are judged by comparing with the mileage like other parts.

Independently replaceable parts such as fuel filters are detected separately.

-tire-

Tires cannot detect direct removal, but can remove wheels.

However, removal is more frequent for replacement than for replacement, so record it as an inspection during maintenance and manually as necessary if necessary.

1 and 2 are views showing a maintenance management method of a vehicle according to an embodiment of the present invention.

Referring to Figure 1 will be described the replacement recommendation and warning control operation according to the mileage.

First, trip computer travel distances are integrated.

Subsequently, when the third maintenance reference distance for each component is reached, a warning lamp for each component is turned on, and the data communication unit constituting the maintenance management system manages systematic maintenance data through wired / wireless communication.

On the other hand, when the 3rd maintenance standard distance for each part is not reached and the 2nd maintenance standard distance for each part is reached, the parts replacement recommendation light turns on, and the data communication unit constituting the maintenance management system provides systematic maintenance data through wired / wireless communication. Manage.

The maintenance standard distance for each part is set as the 1st, 2nd and 3rd standard according to the replacement cycle, and the general replacement cycle is defined as the 2nd maintenance standard distance, and the 1st is set as the shortest distance. If you go beyond the 3rd car and set a long distance, the vehicle will have a problem.

Referring to Figure 2 will be described the control operation for the detection and recording of parts replacement during maintenance.

When the maintenance is detected, the signal input from the corresponding sensors are analyzed to detect the part removal state, and when the removal of the part is detected, the replacement determination unit constituting the maintenance management system records the replacement or records the inspection.

Subsequently, the data communication unit constituting the maintenance management system manages systematic maintenance data through wired / wireless communication.

If maintenance is not detected, part removal is detected for a limited time at the start and a corresponding part error signal is generated.
