Method and device for obtaining real-time oil consumption of automotive vehicle

Abstract

The invention discloses a method and device for obtaining the real-time oil consumption of an automotive vehicle and belongs to the technical field of automobiles. The method comprises the following steps of: collecting and accumulating oil consumption pulse signals, and reading a real-time oil consumption pulse accumulated value according to a high sampling rate; collecting and accumulating speed pulse signals, and reading a speed pulse signal accumulated value according to the high sampling rate; obtaining the real-time oil consumption of the automotive vehicle; if the difference value of the real-time oil consumption obtained at the high sampling rate and the oil consumption at the previous time is in an oil consumption variable threshold range, continuously accumulating the oil consumption pulse signals and the speed pulse signals, and taking the real-time oil consumption obtained at a low sampling rate as the current real-time oil consumption; otherwise, determining the real-timeoil consumption obtained at the high sampling rate as the current real-time oil consumption; and outputting and displaying the current real-time oil consumption. The device comprises an oil consumption pulse accumulating unit, a speed pulse accumulating unit, a real-time oil consumption obtaining unit, a current real-time oil consumption judging unit and an output and display unit. By utilizing the method and device disclosed by the invention, a driver conveniently knows about the oil consumption condition of a vehicle so as to drive in an economical manner.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to a method and device for obtaining real-time fuel consumption of motor vehicles. Background technique [0002] With the strengthening of everyone's awareness of environmental protection, motor vehicle users are paying more and more attention to fuel consumption information. At the same time, in order to make motor vehicle driving more intelligent and humanized, most of the cars currently on the market are equipped with on-board display devices to display real-time fuel consumption. Waiting for driving information. However, these devices have the following problems: either the calculation of fuel consumption is the integral of the fuel consumption signal for a certain period of time, and the effect of real-time response to fuel consumption is not obvious, and the instantaneous fuel consumption suddenly increases or decreases when the vehicle is suddenly accelerated or the brake...

Problems solved by technology

However, these devices have the following problems: either the calculation of fuel consumption is the integration of the fuel consumption signal for a certain period of time, and the effect of real-time response to fuel consumption is not obvious, and the instantaneous fuel consumption is suddenly increased or decreased when the vehicle is suddenly accelerated or the brakes are slammed to the bottom. Under such circumstances, the driver cannot get accurate real-time information; or the response speed is too fast due to the continuous change of the fuel consumption input signal, and the actual fuel consumption display value of the calculated output jumps too much, which brings great inconvenience to the driver to observe and identify the real-time fuel consumption information. difficulty
