Description

Vehicle odometer and its operation method {An automotive drive meter and it's operational method}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automobile odometer and a method of operating the same, and in particular, an odometer of a vehicle and a method of operating the same to display the mileage of various parts of a vehicle, and to reset them to zero according to the driver's selection It is about.

Referring to FIG. 1, in general, an electronic odometer is a system in which rotation of an output shaft of a transmission is guided by a speedmeter cable to drive and count gears. The rotation speed of the transmission is transmitted to the rotation detection unit 1 of the instrument panel. When connected, the calculation unit 2 calculates the electronic circuit according to the detected rotation speed and displays the driving distance on the display unit 3 by using an LCD.

However, the conventional odometer displays the total driving distance (odometer), and when the reset switch (4) is pressed, the trip distance is reset to zero, and the function capable of displaying a short-term trip meter (Trip Meter) indicating the driving of some sections. Have a bay.

However, such a odometer cannot display the traveling distance of consumable parts such as engine oil, transmission oil, brake pads, etc., and thus, there is a problem in that the oil replacement time and the replacement time of the brake pad must be noted separately.

An object of the present invention was created to solve the above problems, by displaying the mileage of each of the consumable parts of the car, and initializes it according to the driver's choice to display the mileage from the desired point of view, It is to provide a vehicle odometer with improved structure so that consumable parts or oil change time can be displayed and its operation method.

The vehicle odometer according to the present invention, which achieves the above object, is characterized in that the display means for initializing the driving distance for a predetermined consumable part of the vehicle according to the driver's selection and displaying the driving distance can be displayed from a desired time point.

The display means includes a rotation sensing unit for sensing the rotational speed of the vehicle, a control unit for calculating and controlling the driving distance by the rotation sensing unit of the vehicle, a display unit for displaying the driving distance calculated by the control unit, and A selection switch for selecting and displaying any one of the consumable parts and a reset switch for initializing the driving distance of the selected consumable part are provided. The consumable part is any one of an engine oil, a transmission oil and a brake pad.

The present invention to achieve the above object in the operating method of the vehicle odometer to display the mileage from a desired time point by initializing the mileage for the predetermined consumable parts according to the driver's selection, by selecting any one of the consumable parts Operating the selection switch 40 to be displayed on / off, and operating the reset switch 50 for initializing the traveling distance of the selected component.

In the step of operating the selection switch, when the selection switch is driven ON for a predetermined time, other consumable parts are sequentially displayed.

According to the features of the present invention as described above, the odometer according to the present invention displays the mileage of the consumable parts, so that the driver can display it from a desired time point so that it is possible to know when to replace the consumable parts or oil.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

Referring to FIG. 2, the odometer of a vehicle of the present invention is provided with display means for initializing a driving distance for a predetermined consumable part of the vehicle according to a driver's selection and displaying it from a desired time point.

The control unit 20 for calculating and controlling the driving distance by the rotation detecting unit 10 for detecting the rotational speed of the vehicle by the display means, the rotation detecting unit 10 of the vehicle, and in the control unit 20 A display unit 30 for displaying the calculated driving distance, a selection switch 40 for selecting and displaying any one of the consumable parts, and a reset switch 50 for initializing the driving distance of the selected consumable part is provided. have. The consumable part is any one of engine oil, transmission oil and brake pads.

In such a configuration, if the consumable part is not selected and displayed, the total mileage of the vehicle is displayed. At this time, the driving distance detected by the rotation detecting unit 10 is displayed on the LCD by the calculation of the control unit 20.

The display unit 30 is provided with a display unit 31 on which a mileage is displayed and an indicator for displaying selected consumable parts (eg, engine oil ENG, transmission oil TM, and brake pad BRK).

The selectable switch 40 may select a desired consumable part, and the reset switch 50 may reset the driving distance to zero. By checking the accumulated mileage from 0, you can know the oil replacement time of consumable parts such as engine oil change, transmission oil change and brake pad replacement.

Referring to FIGS. 2 and 3, an operation method of a vehicle odometer that initializes a mileage for a predetermined consumable part according to a driver's selection and displays a mileage from a desired time point is as follows.

The operation method includes a step of turning on / off a selection switch 40 for selecting and displaying any one of the consumable parts, and a step of manipulating a reset switch 50 for initializing a traveling distance of the selected part. .

When the selection switch 40 is driven ON for a predetermined time in the step of operating the selection switch 40, other consumable parts are sequentially displayed.

If the consumable component is not selected by the selection switch, the total driving distance accumulated with the driving distance is displayed (step 100).

When the selector switch 40 is pressed (step 102), the name of the part corresponding to the short distance trip meter and the set distance are displayed (step 106), and when the reset switch 50 is pressed (step 108), the set distance is Reset to zero (step 110).

Subsequently, if the selection switch 40 is kept pressed for a predetermined time (step 104), the names of the parts corresponding to the engine oil and the set distance are displayed (step 112), and when the reset switch 50 is pressed (step 116). The set distance is reset to zero (step 118).

If the selection switch 40 is kept pressed for a predetermined time (step 114), the name of the part corresponding to the transmission oil and the set distance are displayed (step 120), and when the reset switch 50 is pressed (step 124), the set distance Is reset to zero (step 126).

If the selection switch 40 is kept pressed for a predetermined time (step 122), the name of the part corresponding to the brake pad and the set distance are displayed (step 128), and when the reset switch 50 is pressed (step 132), the set distance Is reset to zero (step 134).

Then, if the selection switch 40 is pressed for a predetermined time (step 130), it waits for a predetermined time (step 136) to display the traveling distance of the vehicle (step 100).

By pressing the selection switch 40 in the same way it is possible to display the distance corresponding to each consumable part, it is possible to accumulate the driving distance from the desired point by pressing the reset switch 50 to reset it to zero. At this time, when the select switch 40 is pressed and the corresponding distance is displayed, the controller waits for a predetermined time (step 136) and returns to the initial screen.

At this time, the selection number of the consumable parts is not limited to this and may be further set. With this configuration, it is possible to know the oil change timing of the parts by displaying the mileage of the consumable parts of the vehicle.

On the other hand, it will be understood by those skilled in the art that various changes and modifications can be made without departing from the spirit of the present invention.

As described above, the present invention displays the travel distance of each part, resets it to zero, and displays the travel distance from a desired time point, so that the appropriate oil change time of consumable parts such as engine oil change, transmission oil change, brake pad change, etc. It can be seen.
