Description

How to display fuel economy of your vehicle

The present invention relates to a method of displaying fuel economy of a vehicle, and more particularly, to a method of displaying driving fuel economy by selecting a driver by calculating fuel economy by a predetermined distance unit using a clock chip.

In general, the fuel consumption rate varies according to the driver's driving habit or road conditions. Therefore, if the fuel consumption is measured and displayed, the driver may feel that his driving habit is not good and the fuel cost is high, thereby changing the driving habit.

Accordingly, an object of the present invention is to provide a method of displaying fuel economy according to a driver's choice by calculating fuel economy using a clock chip.

1 is a block diagram of an apparatus for displaying fuel economy of a vehicle according to an embodiment of the present invention.

2 is a control flowchart for calculating and displaying driving fuel efficiency according to an exemplary embodiment of the present invention.

According to an aspect of the present invention, there is provided a method of displaying fuel economy using a watch chip of a vehicle including a fuel consumption detector and a travel distance detector, the method comprising: inputting a fuel injection amount injected into the vehicle; After the fuel injection amount is input, a process of detecting fuel consumption at a certain mileage when the driving starts, a process of calculating and updating fuel economy according to the mileage after detecting the fuel consumption, and a fuel consumption output selection key may be inputted. And displaying the calculated fuel efficiency on the display device for displaying the calculated fuel efficiency.

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

1 is a block diagram of an apparatus for displaying fuel economy of a vehicle according to an exemplary embodiment of the present invention.

The fuel consumption detector 10 measures the fuel consumption in the fuel tank. The mileage detector 12 detects the mileage of the vehicle. The key input and display unit 14 includes a display device for displaying time and fuel economy, an M, T key for matching hour and minute of time, a fuel input selection key, and a fuel input amount key 24 and a fuel economy output selection key 22 for inputting fuel injection amount. It consists of an input unit. The CPU 16 may be implemented using a clock chip installed in a vehicle. The CPU 16 may include a timer to control the display of the current time by counting the time, to receive and store the fuel injection amount from the key input and the display unit 16, and to detect the fuel consumption amount. The fuel consumption and the driving distance are input from the 10 and the mileage detection unit 12 to calculate fuel economy, and the fuel input is displayed when the fuel consumption output selection key 22 is input from the key input and the display unit 14.

2 is a control flowchart for calculating and displaying driving fuel efficiency according to an exemplary embodiment of the present invention.

1 to 2, the operation of the preferred embodiment of the present invention will be described in detail.

The driver injects fuel to measure fuel economy and presses a fuel input selection key to input fuel injection amount, and then inputs a key for inputting fuel injection amount through the key input and display unit 14. At this time, in step 101, the CPU 16 checks whether the fuel input selection key 20 of the key input unit and the display unit 14 is pressed, and proceeds to step 102 when the fuel input selection key is pressed. In step 102, the CPU 16 enters the fuel injection amount input mode, and receives the fuel injection amount input by the user through the key 24 provided in the key input unit and the display unit 14, and displays the time on the display unit 26. Here, the display unit displays the time in the normal state, and displays the fuel injection amount or fuel economy when the fuel input selection key or fuel output selection key is pressed. The key 24 is used to set the time of the vehicle's clock, and T and M keys and two separate keys are used to set the hour and minute, and the fuel input mode can be entered when the fuel input selection key is pressed. Each press of the button increases the number from 0 to 9 one by one. The M key is a single unit, T is ten units, and the remaining two keys are a key to input fuel injection amount of one hundred and one thousand units. After the fuel injection amount is input, the driver drives the vehicle. In step 103, the CPU 16 checks whether the driving has started and proceeds to step 104 if the driving starts. In step 104, the CPU 16 checks whether the predetermined distance is 1 km, for example, from the distance detecting unit 12, and proceeds to step 105 when the predetermined distance becomes 1 km. In step 105, the CPU 16 detects the fuel consumption detected by the fuel consumption detector 10, stores the fuel consumption in the internal buffer, and proceeds to step 106. In step 106, the CPU 16 calculates fuel economy and stores it in an internal buffer. The fuel economy is calculated by the following equation.

Then, in step 107, the CPU 16 checks whether the fuel economy output selection key 22 is pressed from the key input and display unit 14, and if the fuel economy output selection key 22 is not pressed, the process returns to step 104 above and continuously calculates fuel economy at every 1 km of travel and buffers. If the fuel economy selection key is pressed, go to step 108. In step 108, the CPU 16 displays the fuel efficiency calculated for the distance traveled to the present time on the display unit 26.

As described above, the present invention, after inputting the fuel injection amount after the driver injects fuel, detects the fuel consumption amount according to the mileage, calculates fuel economy at a certain mileage so that the driver can check the fuel economy whenever necessary, There is an advantage in that it is possible to check the fuel economy by using a watch chip installed in a vehicle without having a separate fuel economy calculation device, thereby reducing costs.
