The present invention is a system for the correct use and management of the vehicle to which the electronic control device is applied when the automobile industry is classified into the fields of production, maintenance, use and management,

Korea's Patent No. 0444351 Fuel-Saving Automobile Road Driving Mode Instruction, recording and evaluation system can quantify fuel consumption for driving pattern according to the road driving mode in real time so that the general driver can maximize automobile fuel saving. It's about making sure that you can see the best driving patterns you have, so you can use your car correctly.

It is difficult for drivers to combine the measurement technology that can accurately check the fuel consumption of the car, which causes confusion because it cannot objectively evaluate the effect of fuel saving technology that has been sold domestically and overseas.

In addition, as a number of technologies related to fuel savings are disclosed, automobile makers, automotive technology research institutes, automobile parts related companies, and automobile maintenance companies are also testing a number of fuel saving related technologies in order to develop correct technologies related to automobile fuel savings. The economic loss due to error may be enormous.

Technologies related to fuel saving include: vortex and forced vortex devices in the engine intake, magnet attachment to fuel lines, magnet devices for cutting and attaching fuel lines, battery voltage preservation electronics attached to batteries, and engine fuel Fuel additives, engine oil additives added to the engine oil, fuel pressure regulators to control the pressure of the fuel lines, multi-electrode spark plugs,

Numerous fuel-saving technologies include throttle position sensor variable voltage regulators, power boosters using alloy catalysts, and additives to coolant.

In developing fuel-saving technology, considering the reality that a one-time test cost of an accredited institution that can objectively verify the fuel-saving effect is close to 20 million won, and can be tested only in the laboratory, not on the road, It is a reality that is difficult to test.

In the fuel consumption calculation, if the fuel consumption for a predetermined time is divided by the sum of the injector driving time for a predetermined time based on the driving signal value for driving the fuel injection A4 in the electronic controller A3, it corresponds to 1 ms of injector driving. Save fuel usage,

According to the natural condition (A1), the artificial condition (A2), and the vehicle condition, an error occurs in the fuel consumption reference value per 1 ms of injector driving.

That is, even if the same vehicle varies depending on the fuel pump pressure, pipe loss head, injector use, driver's driving pattern, etc., the fuel consumption per injector driving time based on the injector drive signal value for obtaining the fuel injection amount is determined by the vehicle. Since there is an error in the actual fuel consumption depending on the natural conditions, the artificial conditions, and the condition of the vehicle, the driver should correct this error.

When the automobile industry and the driver change the consumables based on the mileage, but the engine is not driven after starting the engine, the engine consumables do not need to be replaced. In applying different patterns, it is practically unreasonable to exchange consumables based on mileage.

For example, if the engine oil replacement mileage known to the public is 5,000km, the difference between city driving and highway driving will be considerably different.

Even though it is the same car, it is natural that different cycles of engine consumables such as engine oil, spark plug, ignition cable, air cleaner, timing belt, fuel filter, oxygen sensor and automatic transmission oil should be applied differently depending on the driver. As a result, it has not been realized by applying the mileage as a standard.

And the standard of the free after-sales period of the car as the mileage,

The irrationality between the long-distance car and the short-distance car is to accumulate fuel usage so that the standard for consumable replacement cycles and after-sales service periods can be set for reasonable management.

Also, by knowing the usage time of the car, it is possible to accumulate the usage time of the car so that the A / S period can be determined according to the usage time of the car, and the standard of how the driver utilizes it in displaying the car voltage. Although it is not known, it displays the vehicle voltage and sets warning values of the load voltage (voltage at startup) and no-load voltage (voltage during operation) so that the driver can know whether there is a problem with the generator or the battery.

For example, if the no-load voltage is 12 volts when the battery voltage is 12 volts, the battery will not be charged. Therefore, the generator system will know that there is a problem and can be checked. When the load voltage is 9.6 volts or less, Knowing that you need to check the battery so you can do it.

In displaying the vehicle's indoor temperature, conventionally, simply setting the maximum temperature and the minimum temperature at a degree of checking only how many degrees the indoor temperature is, allows the driver to be comfortable driving.

The present invention has been made to solve the above problems,

The total fuel consumption by applying the vehicle fuel consumption, battery voltage, room temperature, and vehicle usage time, the last one-time fuel consumption by car, and the current fuel consumption by car LCD display (B1). Total car use time, last use time for car use, current use time for car use LCD display (B2). Set the fuel consumption reference value for car use LCD display (B3). Car voltage, load voltage warning setpoint, no-load voltage warning setpoint LCD display (B4). Fuel consumption per hour based on driving pattern, Fuel consumption per hour based on driving pattern Setting LCD display (B5), room temperature, minimum temperature warning setting value, maximum temperature warning setting value LCD display (B6). LCD display (B7) allows you to check the consumption of fuel in real time, to check the usage time of the car in real time, and to check the load and no-load voltage of the car. It is possible to check whether there are any abnormalities or battery abnormalities, and to check the fuel consumption per hour based on the driving pattern so that the general driver's driving record (C1) based on the X-axis (hour) and Y-axis (load) is (T1) It is possible to check the fuel usage per hour for the driving record corresponding to the time, and to drive (T2) time in the driving record (C2) of the top driver based on the X-axis (hour) and Y-axis (load). Allows you to check fuel usage per hour for your records. At this time, T1 = T2 enables the general driver to maximize fuel savings by observing the difference in fuel consumption according to the change of driving pattern, and the driver wants to know fuel consumption (mileage per kilometer). In this case, the mileage information detected by the mileage detection unit (vehicle speed, GPS) is converted into a mileage per liter by the control operation unit A10 and displayed on the LCD display unit A13, allowing the indoor temperature of the vehicle to be checked and Set the temperature and maximum temperature warning values to contribute to operator safety.

Therefore, the present invention is intended to enable the correct use and maximize the fuel savings, car A / S and consumables management, car electricity management, car room temperature management.

This object is achieved by a preferred embodiment of the present invention. FIG. 1 is a block diagram illustrating a vehicle use and management system.

Under the natural conditions (road conditions, weather, temperature, etc.) A1 and artificial conditions (operating actions of the driver) A2, fuel injection (injector) is performed in the ECU A3. Due to natural condition (A1) and artificial condition (A2), signals are generated from various sensors such as throttle position sensor, cam angle sensor, cooling water temperature sensor, oxygen sensor, air flow sensor, oxygen sensor, etc. The device A3 calculates and performs the fuel injection A4.

At this time, the driving signal for determining the fuel injection amount generated is detected by the injector driving signal detecting unit A7 and transmitted to the control calculating unit A10.

The driving signal is different for each vehicle, but is driven in units of milliseconds (ms) in units of 1/1000 seconds, and a predetermined time is calculated based on a driving signal value for driving fuel injection (A4) in the electronic controller (A3) in calculating fuel consumption. By dividing the fuel consumption by the sum of the injector driving time for a certain time, it is possible to obtain the fuel consumption corresponding to 1 ms of injector driving.

The control operation unit A10 accumulates the fuel consumption value per injector driving time (ms) determined in the vehicle production process for each vehicle as a reference value in the vehicle fuel consumption reference value setting B3 when the vehicle is used.

At this time, the reference value is a fuel consumption reference value per 1 ms of injector driving according to the natural condition (A1), artificial conditions (A2) will cause some error from the actual fuel consumption value.

In other words, even the same vehicle varies depending on the fuel pump pressure, pipe loss head, injector usage, driver's driving pattern, etc., and thus the fuel per injector driving time determined in the vehicle production process based on the injector driving signal value for calculating the fuel injection amount. The difference between the amount of fuel used and the amount of fuel consumed according to the natural and artificial conditions of the vehicle and the condition of the vehicle is calculated by the driver through the internal variable setting unit (A11). By modifying the reference value by substituting it, it is possible to set an accurate reference in calculating fuel consumption.

The total fuel consumption, the final one-time fuel consumption of the vehicle use, and the current fuel consumption B1 of the vehicle use are displayed on the LCD display unit A13.

In the consumable replacement cycle reference and notification setting through the internal variable setting unit A11, the fuel is stored in the left side of the A, B, C, D, E, ... If you set the standard of consumables replacement cycle and notification as the amount of fuel corresponding to 0,000 L, the same value is set in the right side term, and the right side term is reduced by the corresponding fuel consumption when using the fuel. The display unit A13, the buzzer and the voice notification unit A12 may be recognized by the driver.

For example, the value of fuel consumption-based consumable replacement cycle.

If the engine oil change interval is 15,000KM at the car maker and the official fuel consumption is 15KM / L, the engine oil change cycle fuel consumption is 1,000L obtained by dividing 15,000KM by 15KM / L into the left term. Other consumables can be applied in the same way.

When the driver recognizes that the consumable replacement cycle is performed through the LCD display unit A13, the buzzer, and the voice notification unit A12 in the control operation unit A10, the driver sets the consumable replacement cycle reference and notification through the internal variable setting unit A11. If you click on the exchange on the right side of the consumable item in (B7), the value in the right side coincides with the value in the left side, so that the consumable replacement time can be managed reasonably.

Fuel consumption per hour based on driving pattern, fuel consumption per hour based on driving pattern, and set the reference time setting value of fuel consumption per hour based on driving pattern (0,000 seconds) for 1 second through internal variable setting (A11). If 10 seconds, 60 seconds, 120 seconds, 600 seconds, 3600 seconds, etc. are set, the control operation unit A10 passes through the LCD display unit A13 in the past 1 second, 10 seconds, 60 seconds, 120 seconds, 600 seconds, 3600 seconds.

When it is set to 1 second, the fuel consumption per hour based on the driving pattern is displayed as fuel consumption x 3600 for the past 1 second at the present time.

When set to 10 seconds, the fuel consumption per hour based on the driving pattern is displayed as fuel consumption x 360 for the past 10 seconds at the present time.

When it is set to 60 seconds, the fuel consumption per hour based on the driving pattern is displayed as the fuel consumption x 60 for the past 60 seconds at the present time.

When it is set to 120 seconds, the fuel consumption per hour based on the driving pattern is displayed as the fuel consumption x 30 for the past 120 seconds at the present time.

When set to 600 seconds, the fuel consumption per hour based on the driving pattern is displayed as the fuel consumption x 6 for the past 600 seconds at the present time.

When set to 3600 seconds, the fuel consumption for the past 3600 seconds at the present time is to display the fuel consumption per hour based on the driving pattern.

When the driver sets the reference time for applying the fuel consumption per hour based on the driving pattern of B5 through the internal variable setting unit A11, the fuel consumption per hour based on the driving pattern is converted into the one hour fuel consumption from the present time to the corresponding time in the past. Display usage.

By doing so, it is possible to measure the difference in fuel consumption according to the load change applied to the engine in the stopped state after starting.

Per hour for the driving record corresponding to (T1) time in the driving record (C1) of the 3rd degree of general driver based on the X-axis (time), Y-axis (load) You can check the fuel usage, and you can check the fuel usage per hour for the driving record corresponding to (T2) time in the driving record (C2) of the top driver based on the X-axis (time) and Y-axis (load). To be.

At this time, T1 = T2 enables the general driver to maximize fuel savings by enabling the real-time difference of fuel consumption according to the change of the driving pattern to be confirmed.

When the driver wants to know fuel consumption (mileage KM per liter), the mileage detected from the mileage detection unit (vehicle speed, GPS) is converted into a mileage per liter by the control operation unit A10 and the LCD display unit A13. Mark on.

In the control and calculating unit (A10), the total use time of the car, the last use time of the car use, and the current use time of the car (B2) are displayed on the LCD display unit (A13), which can be used as a standard for the A / S warranty period.

When driving 100M in the instantaneous acceleration performance test, it is possible to know the operating time from the starting point to the arrival point, and compared with the total fuel consumption, the last single fuel consumption of the car, and the current fuel consumption of the car (B1) And acceleration performance can be tested.

When the driver drives the same driving course twice in B1, the fuel consumption at one time is displayed in the final fuel consumption of the vehicle and the fuel consumption at two times is displayed in the current fuel consumption of the vehicle.

In B2, when the driver has driven the same driving course twice, the time of use of the car once is displayed at the time of the last use of the car and the time of use of the car twice is displayed at the current time of use of the car.

In displaying the voltage detected by the voltage detector A5 on the LCD display unit A13 in the control calculator A10, the vehicle voltage is displayed numerically at 00.0 volts as shown in B4, and the driver loads the load through the internal variable setting unit A11. If the voltage warning set value (battery voltage minimum value) and no-load voltage warning set value (value between generator voltage and battery voltage) are set, the control operation unit (A11) and the LCD display unit (A13) and The buzzer may recognize the driver through the voice notification unit A12.

In displaying the temperature detected by the room temperature detector A6 on the LCD display unit A13 in the control calculator A10, the room temperature is displayed numerically at +,-00, 0 ° C as shown in B6, and the driver sets the internal variable setting unit. If the minimum temperature warning set value and the maximum temperature warning set value are set as shown in B6 through (A11), when the maximum and minimum temperature set values are reached, the control display unit A11, the LCD display unit A13, the buzzer and the voice alarm unit (A12) allows the driver to be recognized.

The basic data for the control operation in the control operation unit 10 are stored in the nonvolatile data storage unit A8 and the volatile data storage unit A9, respectively, so that the control display unit A10 displays the LCD display unit A13, the buzzer and the voice notification. Information is provided to the driver through the unit A12.

At this time, when the operation value of the control operation unit is stored in the instantaneous and instantaneous nonvolatile data storage unit A8 and the volatile data storage unit A9 due to the characteristics of the vehicle, the value of the control operation unit is stored when the power supply is unstable or blocked. After storing and terminating in the storage unit A8 and when the electricity supply is stabilized, the control operation unit A10 stores the control operation based on the stored value of the nonvolatile data storage unit A8 and the nonvolatile data storage unit A8. It is stored in the volatile data storage unit A9, respectively, so that the control operation unit A10 can provide information to the driver through the LCD display unit, the buzzer, and the voice notification unit A12, thereby preventing data loss, thereby reducing the total fuel usage and the final use of the car.
