Problems solved by technology

[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 the data acquisition in the diagnosis mode is poor.
Lack of data types and poor timeliness limit what can be displayed on the HUD

Abstract

The present invention provides a method and device for acquiring remaining fuel quantity data based on a monitoring mode, comprising: monitoring data broadcast by a vehicle-mounted computer; analyzing the data to extract remaining fuel quantity data. The present invention provides a method and device for obtaining remaining fuel volume data based on the monitoring mode, which can timely obtain the remaining fuel volume data based on the monitoring mode, thereby avoiding many disadvantages of the existing diagnostic mode, and improving the timeliness and richness of the obtained data sex. The invention can also display the remaining fuel volume data independently monitored, especially during the refueling process, so that the driver can intuitively understand the real situation of the vehicle's current refueling volume, and can even compare it with the refueling volume displayed at the gas station. Thereby preventing the gas station from falsifying the amount of refueling.

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...
