Vehicle oil tank lock control method and device, controller and readable storage medium

Abstract

The invention provides a vehicle oil tank lock control method and device, a controller and a readable storage medium, and relates to the technical field of vehicles. The method comprises the steps that if a vehicle control unit receives a refueling request signal sent by a vehicle machine controller, whether a vehicle meets a preset first refueling condition or not is judged; if yes, a pressure relief instruction is sent to an engine controller; and if it is detected that pressure relief of the high-pressure oil tank is completed, an unlocking instruction is sent to the vehicle body controllerand used for indicating the vehicle body controller to unlock an oil tank lock of the high-pressure oil tank. Whether a vehicle meets a first refueling condition or not is judged; the high-pressure oil tank is subjected to pressure relief on the basis that the vehicle meets the first oiling condition, and finally the oil tank lock of the high-pressure oil tank is opened after pressure relief is completed, so that the situation that the oil tank lock and the oil tank isolation valve are opened at the same time is avoided, the oiling risk of the high-pressure oil tank is reduced, and the oilingsafety of the high-pressure oil tank is improved.

Description

technical field [0001] The present invention relates to the technical field of vehicles, in particular to a vehicle fuel tank lock control method, device, controller and readable storage medium. Background technique [0002] With the continuous development of the automobile industry, in response to the regulations on vehicle fuel vapor, the vehicle fuel tank has been transformed from a traditional mechanical lock fuel tank to a high-pressure fuel tank. [0003] In the related technology, the high-pressure fuel tank includes a fuel tank lock and a fuel tank isolation valve. When the vehicle needs refueling, the fuel tank lock can be opened according to the action of the user. When the user closes the fuel tank lock, the fuel tank isolation valve can be closed together. [0004] However, because the pressure in the fuel tank is higher than the pressure outside the fuel tank, the fuel tank isolation valve and the fuel tank lock are opened together, which will cause a safety ha...
