In order to make the technical problems, technical solutions and advantages to be solved by the embodiments of the present invention clearer, the following will describe in detail with reference to the drawings and specific embodiments.

An embodiment of the present invention provides a vehicle refueling reminder method for a navigation system. The method is shown in FIG. 1 and includes:

Step 11, obtaining the planned route through the navigation system;

Step 12, obtaining the current fuel quantity of the vehicle;

Step 13, judging whether the current oil quantity can guarantee the planned route, and obtaining the judging result;

Step 14, when the judging result indicates that the current fuel quantity cannot guarantee driving the planned route, perform a refueling reminder.

In the embodiment of the present invention, after the route planning is completed through the navigation system, the current fuel quantity of the vehicle is acquired, and when the current fuel quantity cannot guarantee the driving of the planned route, a refueling reminder is performed.

The method is described step by step below.

First proceed to step 11, after the user of the vehicle sets the destination, obtain the planned route to the destination through the navigation system;

Then obtain the current oil quantity of the vehicle through step 12. Preferably, in the physical connection between the existing navigation system and the vehicle body, the physical connection between the navigation system and the vehicle's own oil control system can be added to obtain the current oil quantity of the vehicle. oil volume.

Enter step 13 again, preferably, step 13 may specifically include:

Step 131, calculating the first mileage of the planned route according to the planned route;

Step 132, according to the current oil quantity, calculate the second mileage that the vehicle can currently travel;

Step 133, judging whether the second mileage is greater than the first mileage, and obtaining the judging result.

After obtaining the planned route through the navigation system, the first mileage of the planned route can be easily calculated, and after the current fuel volume of the vehicle is obtained according to the physical connection between the added system and the vehicle's own oil control system, the vehicle can also be calculated. The second mileage that can be driven using the current fuel quantity, if the second mileage is greater than the first mileage, it means that the current fuel quantity of the vehicle can guarantee the planned route, otherwise the planned route cannot be driven.

Of course, there are still many methods for judging whether the current oil quantity can guarantee the planned route, and they will not be listed here.

When the judging result indicates that the current fuel quantity cannot guarantee driving the planned route, it enters step 14 and reminds the user of the vehicle to refuel.

At this time, preferably, a voice reminder is given to the user of the vehicle, and at the same time as the voice reminder, a text reminder can also be used on the navigation system, for example:

Fuel reminder 1: The current fuel level can travel XX kilometers, which does not meet the guide distance, please refuel!

After completing the above reminder, the method also includes:

Detect whether the user of the vehicle needs to refuel nearby, and obtain the first detection result;

When the first detection result indicates that the user of the vehicle needs to refuel nearby, at least one refueling station is recommended to the user through the navigation system.

After reminding the user that the current fuel level cannot guarantee the planned route, the user of the vehicle can be asked whether he needs to refuel nearby by voice and/or text, for example:

Fuel Tip 2: Do you choose to refuel nearby? ——Yes\No (Y\N)

When the user chooses to refuel nearby, at least one gas station is recommended for the user. In practical applications, we can recommend three gas stations that are relatively close. The recommended content includes the name of the gas station, the function of the gas station, and how to reach the gas station The third mileage to be traveled and estimated time of arrival, etc., for example:

Recommended route 1: gas station A, function, mileage to be traveled, estimated time of arrival;

Recommended route 2: gas station B, function, required mileage, estimated time of arrival;

Recommended route 3: gas station C, function, mileage to be driven, estimated time of arrival.

Of course, after reminding the user that the current fuel quantity cannot guarantee the planned route, the user may not choose to refuel. Therefore, the method provided by the embodiment of the present invention also includes:

Detect whether the vehicle refuels after the refueling reminder, and obtain a second detection result;

When the second detection result indicates that the vehicle is not refueled, determine a first reminder position on the planned route;

When it is determined according to the navigation system that the vehicle reaches the first reminder position, a refueling reminder is performed.

Detect whether the vehicle is refueled after the refueling reminder is performed, and the detection method is as follows:

<Method 1>

Whether the vehicle is refueled within a period of time can be detected through the physical connection between the navigation system and the vehicle's own oil control system.

<Method 2>

When asking the user of the vehicle whether to refuel via voice and/or text before, it is determined whether to refuel the vehicle according to the user's selection.

The detection methods are preferably the above two methods, but the embodiments of the present invention may also include other detection methods, which are not listed here.

When the second detection result indicates that the vehicle is not refueled, a first reminder position may be determined on the planned route, and when it is determined according to the navigation system that the vehicle reaches the first reminder position, a refueling reminder is performed again. If the vehicle has not been refueled, the next reminder position can be determined, and when the vehicle reaches the next reminder position, it will be reminded again, which improves the driving safety of the vehicle.

Or determine a plurality of reminder positions on the planned route, detect whether the vehicle reaches a certain reminder position during vehicle driving, and give a refueling reminder to the user of the vehicle when the vehicle reaches a certain reminder position. Examples are as follows:

<Example 1>

The first mileage of the planned route is 100 kilometers, and the second mileage that the vehicle’s current fuel capacity can travel is 80 kilometers. Multiple reminder positions can be set on the planned route, respectively 80 kilometers, 60 kilometers away from the destination. km, 50 km, 40 km, 30 km and 20 km.

When the vehicle travels to 80 kilometers from the destination, the user is reminded to refuel. If the vehicle has not been refueled, when the vehicle travels to 60 kilometers from the destination, the user is reminded to refuel again.

The following is a detailed description of the vehicle refueling reminder process in combination with the actual situation, as shown in Figure 2, including:

Step 1, obtaining the planned route through the navigation system, and calculating the first mileage of the planned route;

Step 2, increase the physical connection between the navigation system and the vehicle's own oil control system to obtain the current fuel volume of the vehicle, and calculate the second mileage that can be driven according to the current fuel volume;

Step 3, judge whether the second mileage is greater than the first mileage, if greater, start navigation, otherwise, enter step 4;

Step 4, reminding the user of the vehicle to refuel, which may be in the form of voice and/or text reminders;

Step five, using voice and/or text to determine whether the user of the vehicle needs refueling, if so, go to step six, otherwise go to step seven;

Step 6, recommending three nearest gas stations to the user of the vehicle, and starting navigation after the user selects one of them;

Step 7, determine the first reminder location, for example, 80 kilometers away from the destination;

Step 8, judging whether the first warning position has been reached, if so, proceed to step 9, otherwise continue driving;

Step 9: remind the user of the vehicle to refuel again, and return to step 5 until it is detected that the vehicle has refueled or the navigation ends.
