Method and device for acquiring residual fuel quantity data based on monitoring mode

Abstract

The invention provides a method and a device for acquiring residual fuel quantity data based on a monitoring mode. The method comprises the steps of monitoring data broadcast by a vehicle-mounted computer; and analyzing the data, and extracting the residual fuel quantity data. According to the method and the device for acquiring the residual fuel quantity data based on the monitoring mode, provided by the invention, the residual fuel quantity data can be timely acquired based on the monitoring mode, so that the disadvantages of an existing diagnosis mode are avoided, and the timeliness and richness of the acquired data are improved. In addition, the monitored residual fuel quantity data can be displayed, and especially in a refueling process, a driver can intuitively know the real situation of a current refueling amount of a vehicle, and even the current refueling amount can be compared with a refueling amount displayed by a gasoline station, so that the gasoline station can be prevented from counterfeiting the refueling amount.

Description

technical field [0001] The invention relates to the field of vehicles, in particular to a data acquisition method and device based on a listening mode. Background technique [0002] The existing vehicle-mounted head-up display is mainly based on the diagnosis mode to obtain the internal data of the vehicle. Although the data acquisition method of the diagnosis mode is simple, many data types cannot be obtained through the diagnosis mode, and the timeliness of data acquisition in the diagnosis mode is poor. The lack of data types and poor timeliness limit what can be displayed on the HUD. Contents of the invention [0003] In order to solve the above problems, the present invention provides a method and device for acquiring remaining fuel quantity data based on a listening mode. [0004] The present invention is realized by following technical scheme: [0005] A method for obtaining remaining fuel quantity data based on a monitoring mode, comprising: [0006] Monitor the...
