Vehicle fuel pre-warning reminding method and system

Abstract

The invention provides a vehicle fuel pre-warning reminding method and system. The method comprises the steps that residual oil quantity data is obtained, and the endurance mileage is calculated according to the residual oil quantity data; a travel destination is obtained, and the travel distance is calculated; the travel mileage is calculated according to the travel distance, and the relation between the travel mileage and the endurance mileage is obtained; if the travel mileage is smaller than the endurance mileage, fuel pre-warning is carried out according to a first preset voice template;if the travel mileage is not smaller than the endurance mileage, fuel pre-warning prompting is carried out according to a second preset voice template. According to the method, a user can be informedwhether the travel fuel quantity meets requirements or not in advance before traveling, so that inconvenience caused by insufficient fuel quantity to traveling of the user is prevented; a refueling strategy is automatically planned for the user, oil consumption increase and environmental pollution caused by excessive refueling are prevented, and repeated refueling caused by insufficient fueling isalso prevented.

Description

technical field [0001] The invention relates to the technical field of automotive electronics, in particular to a method and system for vehicle fuel warning and reminder. Background technique [0002] Cars are becoming more and more important in our lives. Going to school, commuting, traveling by car, etc. With more and more trips, refueling is a necessary prerequisite for driving, but too much refueling will damage the vehicle, increase fuel consumption, and pollute the environment. Increased risk. If there is too little refueling, there will be a risk of not being able to find a gas station during the journey, delaying the itinerary and time, and affecting the fun of travel. [0003] The logical structure of the current fuel alarm system is as follows: figure 1 As shown, it is mainly composed of a fuel data processing instrument and a fuel tank. Its working principle is: a fuel level sensor is built in the fuel tank, and the fuel level sensor transmits the fuel level sig...

AI Technical Summary

Problems solved by technology

[0005] (1) The user cannot accurately know whether the fuel quantity meets the travel needs before travelling;

[0006] (2) The user cannot accurately know the optimal amount of refueling and the best gas station, and from the above analysis, it can be seen that too full or too little refueling will affect the user's travel experience
