Problems solved by technology

This method cannot truly reflect the fuel situation in the car. For example, when encountering large or small bumpy roads, the fuel in the fuel tank will inevitably fluctuate with the bumps of the car. Then, the fuel collected at this time is either Will be greatly lower than the real fuel, or will be greatly higher than the real fuel; and for example, on a steep or gentle slope road, the fuel in the fuel tank must be a slope corresponding to the slope or will rise slightly sloshing, then the fuel collected at this time also cannot reflect the real value in the fuel tank
Therefore, the existing means can not make the display instrument show the real fuel or more real fuel in the fuel tank.

Abstract

The invention provides a method for displaying the residual fuel quantity of an automobile. The method comprises the steps of powering on and igniting an automobile; obtaining the value of fuel in a fuel tank; retrieving a fuel value obtained and a fuel value displayed by a display instrument before last-time stop and power outage from a storage area and obtaining the absolute value of a first difference value of the two; judging whether the absolute value of the first difference value is less than a first preset value; if it is judged that the absolute value of the first difference value is less than the first preset value, obtaining the absolute value of the second difference value between the fuel value obtained this time and the fuel value obtained before last-time stop and power outage; judging whether the absolute value of the second difference value is less than or equal to a second preset value; if it is judged that the absolute value of the second difference value is less than or equal to the second preset value, regarding the fuel value obtained this time as the true fuel value; displaying the fuel value obtained this time. The invention also provides a device for displaying the residual fuel quantity of an automobile.

Description

technical field [0001] The invention relates to a display method and device, in particular to a method and device for displaying remaining fuel oil of an automobile. Background technique [0002] The instrument panel of the car has the function of displaying the remaining fuel of the car. The commonly used technology is to set a sensor in the fuel tank, so that the sensor collects the remaining fuel in the fuel tank of the car at regular intervals, and then displays the remaining fuel on the driving display through the display instrument. in front of the staff. This method cannot truly reflect the fuel situation in the car. For example, when encountering large or small bumpy roads, the fuel in the fuel tank will inevitably fluctuate with the bumps of the car. Then, the fuel collected at this time is either Will be greatly lower than the real fuel, or will be greatly higher than the real fuel; and for example, on a steep or gentle slope road, the fuel in the fuel tank must b...
