Abstract

PROBLEM TO BE SOLVED: To predict the highly accurate exchange timing by providing an operating means in which the data from a storage means is inputted and the exchange timing or the limit traveling distance of each related parts, and a display means to display the operated results by the operating means. SOLUTION: The quantity of the traveling distance L and the quantity of the residual groove T of a tire are surely checked for each opportunity of examination and maintenance such as the diagnosis, the examination and the preliminary inspection of the examination of controlled vehicles in which the address and name of owners are known. As the number of measurements of the traveling distance is increased, the traveling pattern of customers is understood. The mean traveling distance per month can be calculated by the traveling pattern. The data on the limit exchange value of each parts are stored in advance in a data storage device 2. The measured data of each parts and liquid inputted in an operation device 1 and the coefficient to the traveling distance are calculated, the limit distance for exchange and the timing are calculated by the difference with the limit exchange value, and the data are filed.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a predicting apparatus for calculating a time for replacing parts of an automobile.

[0002]

2. Description of the Related Art In the past, at the time of vehicle diagnosis, inspection, vehicle inspection, etc., a maintenance shop clerk has generally determined whether or not this part needs to be replaced after traveling several months or kilometers.
In a system using a computer, 4 for tires
After traveling 000 km, 5,000 for engine oil
It is known that it is necessary to replace the vehicle after traveling 0km or 6 months.

[0003]

The conventional method is a rough guide. For example, the degree of wear of components such as tires and brake pads varies significantly depending on the running condition and driving condition, and cannot be determined simply by the running distance alone. There is a point. In addition, a recent revision of the law abolished the six-month regular inspection, which has caused a problem that the degree of wear of parts becomes more difficult to grasp.

The present invention solves these problems, checks the function of each part of the customer every time the vehicle is inspected and maintained, accumulates data, predicts the time of replacement with high accuracy, and provides convenience to the customer. It is an object of the present invention to provide a device for predicting a part replacement time or the like for ensuring vehicle safety.

[0005]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention provides an input means for inputting the mileage of a vehicle and the amount of change in related objects such as parts of the vehicle according to the mileage. Storage means for storing data from the input means, calculation means for inputting data from the storage means and calculating the replacement time or the limit mileage of each related object, and display means for displaying the calculation result of the calculation means And characterized by the following.

[0006]

DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described with reference to the block diagram of FIG.

[0007] The leftmost column in the figure shows a data input device, from the top L is the running distance, T is the remaining groove of the tire, P ₁ ,
P ₂ , P ₃ ... Input the wear amount of parts such as brake pads and linings, the boiling point of brake fluid, and the like.

Reference numeral 5 denotes an interface, 1 denotes an arithmetic unit, 2 denotes a data storage device, 3 denotes a display, and 4 denotes a printer.

Next, the operation of the prediction device according to one embodiment of the present invention will be described.

Inspection such as at the time of diagnosis, inspection, and preliminary inspection of the inspection of the managed vehicle whose address and name of the owner are known,
Always check the mileage and the amount of remaining tire grooves at each maintenance opportunity.

[0011] In an automobile, the most wearable parts are brake pads and linings in addition to tires. If there is a chance to remove the wheels, the wear amount of the brake pads and linings can be easily measured.

Also, the brake fluid for operating the brake absorbs moisture due to long-term use, and its boiling point drops to cause a life-threatening malfunction. Therefore, by measuring the boiling point, the deterioration state can be checked.

Further, the engine oil is 5,0 for a turbo car.
The service life is twice as long as 00 km and 10,000 km for a normal car, but it can be managed only by the traveling distance.

Further, the degree of deterioration of a shock absorber or the like which affects the riding comfort can be checked.

The numerical values of components and liquids that can be measured as described above are input to the arithmetic unit 1.

Note that the remaining groove amount of the tire is always measured at the time of vehicle inspection, is easy to measure, and may be input from an automatic tire groove measuring device.

Although only one measurement of the current measured value has little effect, the accuracy is improved by accumulating data for the previous measurement and the data before the previous measurement. Further, as the number of times of measurement of the traveling distance increases, the traveling pattern of the customer can be understood. The average traveling distance per month can be calculated from this traveling pattern.

The data storage device 2 stores in advance data on the replacement limit value of each component.

Next, the measurement data of each part or liquid input to the arithmetic unit 1 and the coefficient for the travel distance are calculated, and the exchange limit distance and the time are calculated based on the difference between the exchange data and the exchange limit value.
Create a data file.

Finally, the calculated replacement schedule and the like are displayed on the display, printed out, and the maintenance guide service is promoted to the customer by direct mail or the like.

Here, a tire groove is taken as an example. Note that the tire groove limit is 1 mm.

Suppose today is February 1 and the mileage is 50
0km, 2mm tire groove, January 1 month before the last inspection date
It is assumed that the travel distance is 300 km and the tire groove is 3 mm.

Then, the traveling distance is reduced by 500 km 300
200km at km, groove is 1mm at 2mm minus 3mm.

The coefficient of the amount of wear with respect to the traveling distance is 200 km.
It will wear 1mm when running.

The remaining groove of the tire on February 1st today is 2 mm and the limit is 1 mm, so the margin is another 1 mm. Also, since the average monthly traveling distance was 200 km, the exchange limit date is March 1 which is one month ahead of the above.

[0026]

As described above, according to the present invention, it is possible to predict the replacement time of a highly accurate part by accumulating the traveling distance of the control vehicle and measurement data of the parts and liquids that are worn or deteriorated. This has the effect of facilitating customer convenience and ensuring vehicle safety.
