Abstract

The invention discloses a processing method of automobile fuel quantity display under high fuel consumption and an automobile instrument. The processing method includes: collecting fuel injection quantity data of an engine to calculate fuel consumption rate; judging whether an automobile is in a high-fuel-consumption mode or not according to the acquired fuel consumption rate; if yes, using latest displayed fuel quantity to substrate the acquired fuel injection quantity, and performing linear filtering on a calculation result to acquire a fuel quantity value provided to a user for display. The processing method is more accurate in judgment on high fuel consumption scenes and can well utilize low-pass filtering characteristics of linear filtering to filter out input interference caused by shaking of a fuel tank floater and coming from a fuel quantity sensor.

Description

technical field [0001] The invention relates to the interactive technology of automobile instruments, in particular to a processing method for automobile fuel quantity display under high fuel consumption, an automobile instrument, and a processing method for automobile fuel quantity display. Background technique [0002] The fuel level display has always been an important prompt for human-vehicle interaction. For the amount of oil used in liquid form, the continuous vibration of the tank float during driving is the main problem that needs to be considered for the correct display of the oil amount. In the prior art, a linear filtering algorithm is usually used to filter out the interference caused by the sloshing of the fuel tank float during driving, and an appropriate time lag value is obtained through calibration of the real vehicle as the control parameter of the linear filtering algorithm. [0003] With the further improvement of vehicle performance, there will be more ...
