Endurance mileage calculation control method

Abstract

The invention relates to an endurance mileage calculation control method, comprising the following steps: (1) a combination instrument processor receiving current fuel oil amount of a fuel tank, acquired by a fuel sensor; (2) the combination instrument processor receiving vehicle speed values sent by a ABS control unit; (3) the combination instrument processor receiving instant fuel-injection quantity of an engine, processed by an engine control unit; (4) calculating mileages of vehicle driving; (5) calculating current fuel surplus; (6) calculating average oil consumption amount of a previous section of distance; (7) and according to the remained oil amount and the average oil consumption amount, calculating how far the vehicle can drive with the remained fuel oil. Through correcting the remained oil amount in real time, updating the average oil consumption in real time, and correcting the display method of the endurance mileage, the endurance mileage can be displayed accurately in a humanized manner.

Description

technical field [0001] The invention relates to the field of automotive electronic communication display, in particular to a method for calculating and controlling cruising range. Background technique [0002] There are various disadvantages in the existing technology for the calculation and display of the cruising range, refer to figure 1 : [0003] L: The sampling value of the fuel gauge, the remaining fuel volume obtained - the fluctuation of the fuel volume causes large fluctuations in the cruising range; when the vehicle is driving, the fuel tank shakes, and the fuel sensor also bumps up and down with the fuel, resulting in fuel sampling value There are certain errors. For example: when AFC=10(L / 100km), then 1L of fuel can travel 10km, if the fuel fluctuates at 3L, the display of DTE will fluctuate at 30km. [0004] AFC: Selection of average fuel consumption: [0005] 1. Choose a fixed value, then the calculated DTE cannot truly reflect the actual situation, and can...

AI Technical Summary

Problems solved by technology

[0008] To sum up, there are the following technical problems in the prior art: the cruising range function of automobiles on the market is basically simply using the remaining fuel and the average fuel consumption to calculate how much mileage can be continued on the trip, so the average fuel consumption is basically It will tend to a fixed value, which will not accurately reflect how much distance the remaining fuel can continue to travel under the current vehicle operating conditions; there is also the use of the average fuel consumption of the previous fixed distance for calculation, which will result in a fixed distance. When the distance is an integer multiple of it, the cruising range will jump, which will bring complaints to customers
