In the following description of the present invention, detailed description of known functions and configurations incorporated herein will be omitted when it may make the subject matter of the present invention rather unclear. The following terms are defined in consideration of the functions of the present invention, and these may be changed according to the intention of the user, the operator, or the like. Therefore, the definition should be based on the contents throughout this specification.

≪ Example 1 >

As shown in FIG. 1, the economical operation induction device utilizing the fuel efficiency characteristic of the engine according to the present embodiment is characterized in that the opening rate of the accelerator pedal and the fuel consumption amount (unit time and output An output means 20 for outputting information constructed in the database 10, a current acceleration pedal opening rate of the vehicle and an engine speed And a controller 30 for informing the driver of the optimum fuel consumption amount and guiding the driver to operate the engine with an optimum fuel consumption amount through manipulation of the accelerator pedal.

The database 10 stores numerical values of fuel consumption according to the opening rate of the accelerator pedal and engine speed, and the fuel consumption amount of each engine will be different. The best way to drive an economy is to consume fuel and drive the economy at the current speed, regardless of speed, to drive economically.

Preferably, the accelerator pedal opening amount and the engine speed are set to a predetermined interval, respectively, and a database is constructed. For example, the acceleration pedal opening ratio is increased from "0" to "100" in units of "5" , The engine speed was increased from "idle" to "fuel cut-off speed" in increments of "100" to build up the database by checking the fuel consumption amount by the opening rate of the accelerator pedal / engine speed.

For example, FIG. 1 shows an example in which the opening degree of the accelerator pedal is increased from "25" to "100" by "5", and the engine speed is increased by "100" from "1100" The database is constructed by confirming fuel consumption by the opening rate of the accelerator pedal / engine speed.

1, the opening degree of the accelerator pedal and the number of revolutions of the engine are expressed as numerical values. However, it is also possible to describe them in the range for matching with the current accelerator pedal opening ratio and the engine speed, It is possible to match the number of revolutions of the engine with that of the engine.

The numerical values of the accelerator pedal opening ratio and the engine speed are not limited to the above numerical values. However, it is desirable to build fuel consumption as a natural number that can be easily identified.

The output means is capable of both a screen output and an audio output, and outputs it through the control of the controller. The screen output means may be a variety of displays such as a smartphone of a driver, navigation, and a separate terminal. The sound output means is a speaker. It is possible to output one screen output and one audio output, or both the screen output and the audio output. That is, the economy driving device utilizing the fuel efficiency characteristic of the engine according to the present invention can be implemented in the smartphone of the driver or in the navigation of the vehicle through the application.

The screen output means as the output means outputs the acceleration pedal opening rate, the engine speed and the fuel consumption amount in the form of a two-dimensional table (table) in numerical form.

Meanwhile, it is preferable that the fuel consumption is divided into colors so that the driver can check the optimum fuel consumption at a glance, and the section where the fuel economy is the best is expressed in green and the section where the fuel economy is the worst is expressed in red.

For example, the optimum fuel consumption period may be "213 ", which is the minimum fuel consumption amount based on Fig. 1, or may be a range (213 to 215, optimal) including" 213 ".

The determined optimum fuel consumption period can be displayed as a color tone for easy identification.

Also, the remaining fuel consumption periods can be expressed in different colors. For example, 216 to 219 are light green (safety), 220 to 230 are yellow (attention), 231 to 250 are orange (careful), 251 to 275 Violet (warning), 276 to 300 for red (danger), and 301 or more for black (extreme danger).

The criterion for the division according to the interval is the lowest fuel consumption when the opening rate of the accelerator pedal is over a predetermined value. For example, when the minimum fuel consumption is 10% And 30%, respectively, as the danger zone.

The controller outputs the amount of fuel consumption according to the current driving state of the vehicle through the output means.

That is, the controller is provided with the current vehicle acceleration rate and the engine speed, and can be provided through the DLC (Data Link Connector) of the vehicle and the connection of the present invention device.

The controller requires a gender to be connected to the DLC, and a communication module (Bluetooth or the like) for transmitting the data collected through the gender to the output means 20 is applied. The present invention manages and receives vehicle information such as vehicle speed, fuel consumption, cooling water temperature, mileage, and driving time through the DLC as well as the accelerator pedal opening ratio and the engine speed.

The controller compares the current vehicle information (acceleration pedal opening rate and engine speed) with information in the database and displays the current position (the vehicle position) of the vehicle on the output means 20, 10) to find the corresponding value, compares the current engine speed with the engine speed established in the database, finds a matching value, and then, among the plurality of cells of the output means, For example, when the accelerator pedal opening rate is "40 " and the engine speed is" 1500 ", the fuel consumption amount is " 230 ", marking the position of the vehicle in this place.

The marking of the position of the vehicle can be performed by various methods such as a method of illuminating the marking preformed in the fuel consumption cell with a specific color, a method of blinking the fuel consumption amount of cells.

The driver visually checks the position of the vehicle and also checks the optimum fuel consumption period. The driver will change the opening degree of the accelerator pedal through the operation of the accelerator pedal in order to move the position of the internal combustion engine to the optimal fuel consumption amount range. The driver operates to reduce fuel consumption while checking the position of the vehicle on the screen.

≪ Example 2 >

The present embodiment is characterized in that the instant fuel consumption amount and the decelerating operation / high gear change operation / idling (engine stop) (rapid acceleration operation / low gear operation / idling operation) are informed together with the fuel consumption amount distribution table of Embodiment 1 .

The indication of instantaneous fuel consumption is indicated by the uppermost red color and sequentially yellow, green, and white. For example, in 10 steps, red indicates the situation with the most instantaneous fuel consumption, which is indicated at the time of rapid start or rapid acceleration. Yellow indicates a state in which momentary fuel consumption is slightly higher, and green indicates less consumption. In the case of white, it indicates a state in which the fuel consumption is cut off when the driver releases the accelerator pedal while the engine power is connected to the vehicle body during driving (DFCO: Deceleration Fuel Cut-Off). The quantity of white, green, yellow and red is freely adjustable.

The 10-step criterion can not be limited to a numerical value because the engine applied to the vehicle is different. When making each engine database, the instantaneous fuel consumption amount is indicated by "0" and the maximum value is divided into 10 equal parts.

The decelerating operation guidance is to guide decelerating operation to reduce excessive fuel consumption when the condition of the vehicle is rapidly accelerated, and "RAW" lights on the screen and an alarm sound can be output together.

RAW is an abbreviation of Rapid Acceleration Induction and is an example of guiding deceleration operation due to rapid acceleration.

The deceleration operation guidance is to guide deceleration after determining rapid acceleration. When the instantaneous fuel consumption is at least 90% of the maximum value and is maintained for more than 3 seconds, the deceleration operation guidance is judged as a rapid acceleration running and the deceleration operation is guided. 4, and when the red LED lights up for 3 seconds, it is judged as rapid acceleration and induces decelerating operation.

High-speed gear operation guidance is to guide the driver to shift to a high-efficiency high-gear when there is no deterioration in acceleration performance when the driver uses a low-fuel-efficient low-gear in a manual transmission. It will light up and make you hear the alarm sound. USI stands for Up Shift Induction.

The high-speed gear operation guide guides the shifting of the high-speed gear when the constant-speed running state is a low-speed gear, for example, five seconds after a predetermined time elapses (see FIG.

If the idle stop condition is met on the vehicle in which the driver is driving, the idle stop instruction is to "ISI" on the screen and to be able to hear the alarm sound to prevent unnecessary consumption of fuel. ISI stands for Idle Stop Induction.

As shown in Fig. 6, the idle stop guidance flow guides idle stop (engine stop) when, for example, idling is detected and idling is for a predetermined time, for example, 10 seconds.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments. It is to be understood, however, that the invention is not to be limited to the specific forms thereof, which are to be considered as being limited to the specific embodiments, but on the contrary, the intention is to cover all modifications, equivalents, and alternatives falling within the spirit and scope of the invention as defined by the appended claims. .
