Problems solved by technology

However, sometimes due to the carelessness of the user or the failure of the fuel gauge, the car will go on the road without enough fuel, and when the user drives the vehicle to an unfamiliar environment and the fuel of the car is about to run out, the car will run out. The GPS navigation device cannot immediately help the user to find the existing gas station nearby, resulting in an embarrassing situation of insufficient fuel on the way

Embodiment Construction

[0032] figure 1 A block diagram of a vehicle with the function of planning a refueling route is shown according to an embodiment of the present invention. Please refer to figure 1 , the vehicle 100 provided in this embodiment may include an oil quantity measuring unit 110 , an encoder 130 and a positioning system 150 . Wherein, the fuel quantity measuring unit 110 is used for measuring the state of the fuel tank 120 and generating a fuel quantity signal.

[0033] In this embodiment, the oil quantity measuring device 110 may include a float 111 , a variable resistor 112 , a metal rod 113 , a microcomputer 114 and an oil quantity display unit 115 . Wherein, the floating ball 111 is disposed in the oil tank. The metal rod 113 is coupled between the floating ball 111 and the variable resistor 112 for adjusting the resistance value of the variable resistor 112 according to the position of the floating ball 111 on the oil surface of the fuel tank 120 .

Abstract

The invention relates to a carrier having a function for defining refueling path, comprising a fuel quantity metering unit, a coder and a positioning system, wherein the fuel quantity metering unit meters the state of an oil tank and generates a fuel quantity signal; the coder is coupled with the fuel quantity metering unit for coding the fuel quantity signal and a voltage signal to add the fuel quantity signal into the voltage signal; the positioning system comprises a decoder and a central processing unit; the decoder is coupled with the coder for decoding the voltage signal having the fuel quantity signal to separate the fuel quantity signal and the voltage signal; the central processing unit is coupled with the decoder for comparing the fuel quantity signal with a preset value, to control the carrier to rearrange a refueling path on a preset line or not.

Description

technical field [0001] The present invention relates to a navigation method and device, and in particular to a method capable of automatically planning a refueling route and its vehicle. Background technique [0002] With the advancement of science and technology, means of transportation has become one of the important inventions in modern development. The birth of vehicles such as automobiles has rapidly shortened the distance between human beings. Due to the rapid development of cities, the connection of roads has become more and more complicated, and the scope of its coverage has also increased. Therefore, when the road structure is complex or unfamiliar, there will be troubles on how to reach the destination. The emergence of the Global Positioning System (Global Position System, hereinafter referred to as GPS) has brought great convenience to human beings, enabling people to drive safely through GPS navigation in unfamiliar environments. [0003] Although, the car GP...
