Method for calculating driving mileage of motor vehicle instrument by means of comprehensive factors

Abstract

The invention provides a method for calculating the driving mileage of a motor vehicle instrument by means of comprehensive factors. The method for calculating the driving mileage of the motor vehicle instrument by means of the comprehensive factors comprises a step 1 of setting leaving-factory oil consumption according to comprehensive oil consumption declared by the vehicle; a step 2 of calculating target remaining oil quantity; a step 3 of obtaining oil consumption per kilometer according to the fuel-injection quantity of the EMS; a step 4 of calculating target average oil consumption according to the oil consumption per kilometer; and a step 5 of calculating the driving mileage according to the target remaining oil quantity and the target average oil consumption. The method for calculating the driving mileage of the motor vehicle instrument by means of the comprehensive factors can correct the driving mileage in time when the vehicle is in different road conditions and drivers have different driving habits. The influence of the vehicle on the driving mileage when the vehicle travels on a bumpy road or is parked on a rampway is especially avoided, and more reliable driving mileage can be provided for the driver.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to a method for calculating the cruising range by a vehicle instrument through comprehensive factors. Background technique [0002] When calculating the cruising range of the car instrument, many of them set the fuel consumption as a fixed value, which will cause the cruising range not to reflect the current road conditions. If the value is too small, if the calculation is the average fuel consumption within 10KM, it will cause the cruising range to jump too quickly; The average fuel consumption, the total fuel consumption divided by the total mileage, will cause the problem that the cruising range changes too slowly after the vehicle travels a long distance. [0003] When taking the remaining oil quantity, because of the bumps on the roadside, the oil float fluctuates up and down and the error of AD sampling will lead to a large error in the value of the oil quantity.

Problems solved by technology

And then cause the remaining oil quantity of the motor vehicle in its calculation to change greatly, thereby affecting its target remaining oil quantity, the target average fuel consumption described in the second invention, the fuel consumption of the last tank of oil and this tank of oil is taken as important Taking into account the factors, assuming that a tank of fuel is 50L, the fuel consumption of the high-speed is 6L / 100KM after the user refuels (generally before the high-speed) and the high-speed fuel consumption is 6L / 100KM, which can drive 833.3KM. It is 9L / 100KM, which means that the user will be affected by the road conditions of the city he drove before within 800 KM of the expressway, and the algorithm makes the correction not timely enough
