Abstract
The present invention relates to a travelable distance arithmetic device and a travelable distance fuel amount method thereof, and more particularly to a traveling distance calculating method for checking whether a fuel remaining amount of a fuel gauge satisfies an overcurrent mode entry condition, And checks whether the vehicle is lubrication, and calculates the travelable distance fuel amount by using an arithmetic expression determined according to whether the vehicle is lubrication.
Description
The present invention relates to a travelable distance calculator capable of calculating a travelable distance more accurately by minimizing a difference between a remaining amount of fuel displayed on the fuel gauge and a remaining amount of fuel based on the fuel consumption of the engine, and a travelable distance fuel amount method thereof.
In general, a trip computer informs a driver of various information related to driving, such as a traveling distance, an average traveling speed, a traveling distance, an outside temperature, and a driving time.
In particular, the trip computer computes and displays the travelable distance that can be traveled with the remaining fuel by using the fuel consumption amount of the vehicle and the fuel gauge fuel amount, so that even if the fuel low warning light is illuminated during driving, the driver can operate without being embarrassed.
However, in an actual vehicle, it is possible to refuel more than 15 liters (L) while the fuel gauge is full. However, since the fuel amount can not be detected through the fuel gauge, a large error occurs in calculation of the travelable distance.

In the step of confirming whether or not the entry into the overcurrent mode entry condition is satisfied, it is checked whether the remaining fuel amount is equal to or greater than a fuel amount obtained by subtracting 1 liter from the full load amount.
Further, in the calculating of the travelable distance fuel amount, the travelable distance fuel amount is calculated by adding 2 liters to the full charge amount when the vehicle is in lubrication.
In the calculating of the distance travelable fuel amount, the travelable distance fuel amount is calculated by subtracting one-half of the fuel consumption amount from the previous travelable distance fuel amount when the vehicle is traveling or stopping.
In the step of confirming whether or not the overcurrent mode release condition is satisfied, it is determined whether the remaining fuel amount is less than a fuel amount less than 3 liters from the full charge amount.

The operation unit is characterized in that when the remaining fuel amount is equal to or more than the amount of fuel less than one liter in the full charge amount, the operation enters the full charge mode.
Further, the calculation unit may calculate the travelable distance fuel amount by adding 2 liters to the full charge amount when the vehicle is in lubrication in the overcurrent mode.
The calculation unit may calculate the travelable distance fuel amount by subtracting one-half of the fuel consumption amount from the previous travelable distance fuel amount when the vehicle is traveling or stopping.
In addition, the calculation unit releases the overcurrent mode and enters the normal mode when the remaining fuel amount is less than the fuel amount less than 3 liters from the full charge amount.
