Vehicle fuel quantity early warning method based on historical fuel consumption and path planning

Abstract

The invention discloses a vehicle fuel quantity early warning method based on historical fuel consumption and path planning. The method comprises the steps of: obtaining the current position information of a vehicle and the current fuel quantity of the vehicle at regular time, carrying out the path planning of the vehicle from the current position to a destination, and obtaining a vehicle planning path; obtaining standard historical fuel consumption and the average fuel consumption of the vehicle, taking the maximum value of the standard historical fuel consumption and the average fuel consumption as the use fuel consumption of the vehicle, and calculating the fuel quantity needed by the vehicle planning path according to the use fuel consumption; comparing the current fuel quantity with the fuel quantity required by the vehicle planning path; and when the current fuel quantity is smaller than the fuel quantity required by the vehicle planning path, carrying out refueling reminding on the vehicle. According to the vehicle fuel quantity early warning method based on the historical fuel consumption and the path planning of the invention, in the navigation process, with emergencies in yawing and driving processes considered, fuel quantity early warning can be continuously carried out, and the situation that a user cannot reach a destination due to the fact that refueling is not carried out in time is avoided.

Description

technical field [0001] The invention belongs to the technical field, and in particular relates to a vehicle fuel quantity early warning method based on historical fuel consumption and route planning. Background technique [0002] Car owners lack of attention to the vehicle's fuel volume, inaccurate estimates of the vehicle's fuel mileage, and unclear locations of gas stations along the way often cause car owners to miss suitable refueling opportunities when the remaining fuel is insufficient. Therefore, on the basis of route planning and navigation, it is very necessary to add a refueling reminder function for car owners, especially for truck owners who drive in remote areas. Contents of the invention [0003] The purpose of the present invention is to provide a vehicle fuel quantity early warning method based on historical fuel consumption and route planning, which provides real-time refueling early warning function for car owners during the navigation process. [0004] ...
