Embodiment Construction

[0060] The specific embodiments of the present disclosure will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present disclosure, but not to limit the present disclosure.

[0061] As described in the background art, when a dual-purpose fuel vehicle uses natural gas as a fuel, the fuel level does not change, which may cause a fuel OBD false alarm failure. In practice, when natural gas is used as fuel, the fuel level does not change. When the vehicle travels for about 300km, the fuel level remains unchanged, which does not meet the normal conditions of fuel OBD diagnosis, causing the fuel OBD to be mistaken for the fuel level sensor. After the MIL is activated, the driver will think that the vehicle is faulty, but in fact there is no related fault in the vehicle, which is easy to cause trouble for the driver.

[0062] In addition, the Nat...

Abstract

The disclosure relates to a fuel level control method, device and system to solve the problems existing in the translation gas system of a dual-purpose fuel vehicle when the on-board diagnostic system performs fault diagnosis. The method is applied to a gas system controller, the gas system controller is respectively connected to a fuel level sensor and a fuel controller, and the fuel level sensor communicates with the fuel controller through the gas system controller, The method includes: when the vehicle is powered on, acquiring power source information of the vehicle, wherein the power source information is fuel or gas; acquiring the first liquid level of the fuel tank of the vehicle through the fuel level sensor level information; according to the power source information and the acquired first liquid level information, generate second liquid level information for sending to the fuel controller; send the second liquid level information to the fuel controller.

Description

technical field [0001] The present disclosure relates to the field of vehicles, and in particular, to a fuel level control method, device and system. Background technique [0002] A dual-fuel vehicle is a vehicle with two independent fuel supply systems, one uses natural gas as fuel and the other uses oil as fuel. These two fuel supply systems can respectively supply fuel to the cylinder as the driving force for the vehicle source, but the two cannot jointly supply fuel to the cylinder. When the dual-fuel vehicle uses natural gas as fuel, the fuel level will not change because the fuel is not used. As the mileage increases, the fuel OBD (On Board Diagnostics, on-board self-diagnosis system) cannot detect the fuel level. It is mistaken for the fuel level sensor of the fuel tank to be faulty, and then the performance of the fuel level sensor is reported to be faulty. At this time, the performance of the fuel level sensor is normal and fault-free, which is a false alarm fault,...
