Abstract

The invention discloses a method for displaying a motor vehicle instrument system. The method comprises the steps: the alarm oil quantity and the oil tank minimum guarantee oil quantity are preset; when the remaining oil quantity of an oil tank reaches the alarm oil quantity, the endurance mileage at the moment is obtained; and then the endurance mileage is calculated according to the following mode: every time when the oil spraying quantity is increased by the oil quantity of the same numerical value, the endurance mileage is decreased by one kilometer, and the remaining oil quantity of the oil tank and the endurance mileage are synchronously displayed, wherein the oil quantity of the same numerical value is that the difference value of the preset alarm oil quantity and oil tank minimum guarantee oil quantity is divided by the endurance mileage at the moment. The invention further discloses the instrument system. The instrument system comprises a sensing module, an ESM, a calculationmodule and a display module, and the ESM is connected with the sensing module, the calculation module and the display module. By synchronously displaying the remaining oil quantity of the oil tank andthe endurance mileage on an instrument, a user can visually feel, the situation that the user misjudges the fuel oil quantity only from the endurance mileage, and consequently a vehicle breaks down is prevented, and meanwhile a fuel oil pump is also protected.

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 ...
