Abstract

The present invention relates to a warning method of oil replacement time of a vehicle to grasp the engine oil and the mission oil replacement time of the vehicle to turn on a warning light when a certain time is reached so that the driver can easily know the replacement time of the oil.

The present invention cumulatively calculates the mileage by the vehicle speed wheel sensor in the case of ABS vehicle, and cumulatively calculates the mileage by the mission sensor in the case of LCD cluster vehicle to automatically turn on the warning light on the cluster when the cumulative distance is greater than the set value. It has the effect of letting the driver know when to replace the engine and mission oils.

Description

How to change the oil when the vehicle is replaced

The present invention relates to a vehicle, and in particular, the oil of the vehicle to grasp the replacement time of the engine oil and the mission oil of the vehicle to turn on the warning light when a certain time or the replacement time is over, so that the driver can easily know the replacement time. It is about alarm method of replacement time.

In general, oil is injected into an engine, a mission, or a brake of a vehicle, so that each component operates smoothly when the vehicle is driven.

However, in the related art, since the driver is not familiar with the exact replacement cycle of the oil or consumables, it is inconvenient to write down the replacement time by guessing or changing them.

The present invention has been made in order to solve such a conventional problem, it is an object of the present invention to provide a vehicle oil replacement time warning method that can inform the correct replacement cycle by turning on the alarm light when the replacement period of the vehicle oil.

The present invention for achieving the above object is a odometer for counting the mileage when driving the vehicle, sensing means for detecting the distance counted by the mileage, and a speed sensor attached to the wheel of the vehicle for detecting the speed when driving And a microcomputer that stores the output of the sensing means and the speed sensor and outputs a signal of a predetermined level when the predetermined value is exceeded compared to a preset value, and lights when the predetermined signal is output from the microcomputer to alert the oil replacement time. In the first step of setting the warning light to set the driving distance (S _engine ) _SUM = 0 after replacing the engine oil and the driving distance (S _mission ) _SUM = 0 after the mission oil is replaced by the manual switch in the ignition on state. , cumulative distance, (S _{engine) SUM,} (S _{mission) SUM} is the second step of comparing the judgment is greater than the set value, the (S _engine) and _SUM (S _{mission) SUM} is greater than the set point And light the warning lamp 50 in the cluster, (S _{engine) SUM} and (S _{mission) SUM} is less than the set value when the ABS vehicle calculates the distance traveled by the vehicle wheel (WHEEL) sensor, and for LCD cluster vehicle mission sensor and a third step for calculating a traveling distance by and start-up during the off (S _{engine) SUM} = (S _{engine) SUM} + S _engine, (S _{mission) SUM} = (S _{mission) SUM} + S establish a _mission to store this second It is characterized by consisting of four steps.

Hereinafter, with reference to the accompanying drawings an embodiment of the oil replacement time alarm method of the present invention will be described in detail.

1 is a block diagram showing the hardware configuration of the present invention, the odometer 10 for counting the mileage when the vehicle travels, the sensing means 20 for sensing the distance counted by the mileage 10 and And a speed sensor 30 attached to the wheel of the vehicle to detect the speed during driving, and store the thrust of the sensing means 20 and the speed sensor 30 and output a predetermined signal when the set value is exceeded by comparing with a preset value. And a warning lamp 50 which lights up by a predetermined signal output from the microcomputer 40 to inform the oil replacement time.

If the present invention having such a configuration will be described in detail with reference to FIG.

First, when the engine oil and mission oil are replaced at the start-up state, set the driving distance (S _engine ) _SUM = 0 after replacing the engine oil and the driving distance (S _mission ) _SUM = 0 after the mission oil is replaced by a manual switch ( Step S1, S2).

After that, the driver continues to drive the vehicle, and the microcomputer 40 receives data from the sensing means 20 and the speed sensor 30 for detecting the counted distance from the odometer 10 and compares the data with the set value. Determine (step S3).

At this time, if the (S _engine ) _SUM and (S _mission ) _SUM is greater than the set value, the microcomputer 40 outputs a signal of a predetermined level to turn on the warning lamp 50 of the cluster (step S4).

However, if (S _engine ) _SUM and (S _mission ) _SUM are smaller than the set value, it is not yet in the time of replacement, and at this time, the ABS calculates the mileage by the wheel sensor and calculates the If the distance calculated by the mission sensor is calculated (step S5).

Then, it is determined whether the start is in the off state (step S6), and if it is not in the off state, the driving distance by the ABS wheel sensor and the driving distance by the mission sensor are calculated again.

If the engine is off, set (S _engine ) _SUM = (S _engine ) _SUM + S _engine , (S _mission ) _SUM = (S _mission ) _SUM + S _mission and store it in the ROM of the microcomputer 40. (Steps S7, S8).

Therefore, according to the present invention, the process of accumulating the running distance at start-up and storing it in the ROM of the microcomputer 40 at the start-off is repeated, and when the cumulative distance is larger than the set value, the oil is stored through the warning lamp 50 of the cluster. It will alert you of the replacement time.

As described above, the present invention calculates the replacement time of the engine oil and the mission oil of the vehicle and automatically displays it through the warning light of the cluster when the replacement time is replaced. It has the effect of eliminating.
