Method for displaying motor vehicle instrument system, and instrument system

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...

AI Technical Summary

Problems solved by technology

[0005] 1. The evasion method of not displaying the cruising range up to 0km, and no longer displaying it when the cruising range is lower than Xkm (X value is customized)

[0006] 2. The cruising range is not displayed when the remaining fuel in the fuel tank reaches 0

[0007] 3. The cruising range is displayed to 0km but the remaining fuel in the fuel tank does not display to 0

[0008] In the above methods, the remaining fuel in the fuel tank is displayed to 0 but the cruising range has not dropped to 0, causing the user to misjudge and continue to drive the vehicle without fuel and break down; or the remaining fuel in the fuel tank is not 0 but the cruising range has reached 0km, causing users to complain
