Abstract
Description
technical field
[0001] The invention relates to the technical field of automobiles, in particular to a method for displaying an instrument system of a motor vehicle and an instrument system. Background technique
[0002] Motor vehicle instrumentation can effectively reflect the remaining fuel volume and cruising range of the motor fuel tank, and provide reliable information for drivers, especially for people who drive long distances.
[0003] Usually, EMS (Engine Management System) is used to control the fuel injection quantity to calculate the fuel consumption. The accuracy of the fuel consumption is high, but there is at least one of the following adverse phenomena: due to the limitation of the fuel tank design, in the full fuel section , there is a large error between the initial oil volume of the fuel tank and the actual oil volume of the fuel tank. When the fuel is gradually consumed, the full fuel error will gradually appear, and the value of the cruising range and th...

Embodiment Construction
[0023] The specific embodiments described here are only used to explain the present invention, not to limit the present invention. The present invention will now be described in detail with reference to the accompanying drawings.
[0024] An embodiment of the present invention is a method for displaying the instrument system of a motor vehicle. The instrument system is used to preset the alarm fuel volume and the minimum guaranteed fuel volume of the fuel tank. When the remaining fuel volume of the fuel tank reaches the alarm fuel volume, the cruising range at this time is obtained, and the following method will be used later Calculation of cruising range: When the fuel injection volume increases by the same amount of fuel, the cruising range will be reduced by 1 km, and the remaining fuel in the tank and the cruising range will be displayed simultaneously. Among them, the fuel quantity of the same value is the difference between the preset alarm fuel quantity and the minimum ...
