Abstract

The invention discloses a fuel display control system and method for a double-fuel automobile. The fuel display control system for the double-fuel automobile comprises a fuel conversion switch, an engine management system, a combined instrument, a fuel gas pressure gauge, a fuel oil sensor and a power supply. The fuel conversion switch transmits a working mode level signal to the engine management system, the engine management system outputs the working mode signal to the combined instrument, the combined instrument reads fuel data and transmits the fuel data to a driver, and the driver drives a display unit to display the storage quantity of fuels. The fuel display control system for the double-fuel automobile can display the storage quantity of two fuels by using one display unit. According to the fuel display control method for the double-fuel automobile, display of the storage quantity of double fuels is realized on one display unit by switching the fuel conversion switch, the operation is convenient and fast, meanwhile, wiring of circuits can be reduced, and the cost is reduced.

Description

technical field [0001] The invention relates to an instrument display control system and a control method, in particular to a fuel display control system and a control method of a dual-fuel vehicle. [0002] Background technique [0003] Most of the existing dual-fuel vehicles are modified vehicles, that is, a fuel supply system is added on the basis of the original fuel vehicle, such as a CNG or LPG gas supply system. The fuel display function device of this dual-fuel vehicle also needs to be additionally set up, therefore, the increased fuel display and indication function device can only be arranged and installed according to the spatial position of the existing vehicle under the premise of not affecting the normal use of the vehicle. In order to solve this problem, the combined instrument device disclosed in the Chinese invention patent with the publication number CN101337509A includes a first fuel display table and a second fuel display table, and the combined instrume...
