Vehicle fuel refuelling prompting system and method based on internet of vehicles

Abstract

The invention relates to the technical field of vehicle electronics, in particular to a vehicle fuel refuelling prompting system and method based on internet of vehicles. The method comprises the following steps: acquiring cloud map data and vehicle position information; calculating the distance between a vehicle and the nearest filling station according to the cloud map data and the vehicle position information in real time; receiving a residual fuel amount signal and an instantaneous fuel consumption value signal, and calculating endurance mileage of the vehicle; judging the existence of a fuel exhaustion risk according to the endurance mileage and the distance value of the nearest filling station, and performing fuel deficiency warning when the fuel exhaustion risk exists. A route from the vehicle to the nearest filling station is calculated according to the distribution situation of filling stations on the periphery; the route between the vehicle and the nearest filling station is compared with the endurance mileage; whether to perform the fuel deficiency warning or not is judged, so that an anchor phenomenon caused by the fact that the filling station does not exists at a long distance on the periphery is avoided.

Description

technical field [0001] The invention relates to the technical field of automotive electronics, in particular to a vehicle fuel filling prompt system and method based on Internet of Vehicles. Background technique [0002] With the continuous improvement of our country's living standards and the implementation of the national statutory holiday highway toll-free policy, more and more people choose to go out for self-driving tours with their families during holidays such as the Golden Week holiday. When driving on the highway for a long time, judging the amount of remaining fuel in the car is a headache for the driver. The traditional fuel alarm of the car instrument is set based on judging whether the cruising range of the vehicle is greater than 50km. This setting has certain defects: [0003] On the one hand, due to the lack of supporting facilities such as gas stations on expressways in our country, there may be no gas stations for hundreds of kilometers on some road sectio...

Problems solved by technology

In this case, even if the fuel alarm is activated, the fuel cannot be replenished within the cruising range, and it is still prone to breakdown;

[0004] On the other hand, when the fuel level in the vehicle is lower than the alarm threshold, the traditional vehicle will remind the driver by lighting the fuel warning indicator light, which requires the driver to pay attention to the fuel warning indicator light all the time. Fatigue, it is easy to ignore the judgment of the fuel level, and it is very easy for the vehicle to break down on the highway due to fuel exhaustion
