The gas station database 110 is used to store the location and related service information of each gas station for use by the gas station search module 109;

As shown in Figure 4, the navigation method of the navigation terminal of the present invention includes the following steps:

Step 201, receive the GPS signal through the GPS positioning module 101, and locate the position of the navigation terminal;

Step 202, receiving the destination input by the user through the human-computer interaction module 102;

Step 203, the path planning module 103 calls the road database 104 according to the location and destination of the navigation terminal, plans the navigation path and displays it;

Step 204, the navigator starts to navigate, and the user drives;

Step 205, the fuel consumption judging module 105 judges the amount of fuel stored in the fuel tank, and at the same time judges whether the fuel stored is enough for the driver to reach the destination; if the destination can be reached, then step 205 is repeated; if not, then step 206 is executed;

Step 206, call the gas station database 110, and search for gas stations around the current location of the vehicle through the gas station search module 109;

Step 207, through the distance acquisition module 108, calculate the gas station that the fuel tank can reach, and display it to the driver through the human-computer interaction module 102 as a list;

In the prior art, the navigation terminal does not care about whether the remaining fuel can reach the destination, because the driver does not know how far ahead there is a gas station or forgets to confirm the amount of fuel stored in the fuel tank, so it breaks down in the picture heading to the destination. This is the last thing a driver wants to happen.

This program uses the navigator to monitor whether the vehicle's fuel storage can reach the destination, reminds the driver in time, and calculates the gas station that can be reached for the driver to choose. After the driver chooses, re-plan and guide the route to make the driver more Comfort, peace of mind and peace of mind. Using this navigation technology, it can promptly remind the driver whether the vehicle can reach the destination with fuel, and search for the most suitable gas station for the driver to choose, thus avoiding the situation of breaking down halfway due to insufficient fuel.

The invention provides a method for monitoring and navigating a car. Existing navigation technology does not take into account the relationship between the fuel stored in the vehicle's fuel tank and the amount of fuel used to reach the destination. The navigator of the present invention reminds the driver by comparing the required fuel consumption of the planned route with the fuel storage capacity of the fuel tank, and gives a list of gas stations that can be reached for the driver to decide, and finally guides the driver. The present invention monitors the oil stored in the fuel tank in real time through a navigator to determine whether the destination can be reached, and if the destination cannot be reached, the driver is reminded in time, the driver is provided with a gas station to choose, and the route planning and guide.
