Abstract

The invention provides a control method and device of a vehicle fuel system. The control method of the vehicle fuel system comprises any one or combination of multiple steps in the following three steps that before an engine is started, pre-detection operation is carried out; when the engine is started, start self-detection operation is carried out on the fuel system; and after a vehicle is started, running self-detection operation is carried out on the fuel system. According to the control method and device of the vehicle fuel system, at any one or multiple moments before the engine is started, when the engine is started and after the vehicle is started, the work state of the vehicle fuel system is monitored in real time, self diagnosis of the vehicle fuel system can be achieved, failuresof the vehicle fuel system can be found in time, and safety and reliability of the vehicle can be effectively guaranteed.

Description

Technical field [0001] The present invention relates to the field of vehicle technology, in particular to a control method and device of a vehicle fuel system. Background technique [0002] With the improvement of people's living standards, automobiles have entered thousands of households, and gradually transition from transportation tools to intelligent living facilities. While people enjoy the convenience brought by cars, car safety has also been paid more and more attention, and intelligent safety configuration has gradually become the main selling point of various car manufacturers. For fuel vehicles, due to the high risk of flammability and explosion of the fuel used, the fuel system must ensure the safety of fuel storage. In addition, the normal operation of the engine is also related to driving safety, and the fuel system also needs Ensure the safety and reliability of the oil pipeline. [0003] In related technologies, the safety of the fuel system is mainly reflected in ...
