Abstract

The embodiment of the invention discloses an electric fuel pump control method and device, electronic equipment and a storage medium, and belongs to the technical field of vehicle control. The electric fuel pump control method comprises the steps that if a power-on event is monitored, a value of a starting parameter of oil pumping control logic is obtained; and according to the value of the starting parameter, whether an electric fuel pump is controlled to work through the oil pumping control logic or not is determined. According to the technical scheme, the phenomenon that oil pumping is started in the power-on process before fuel oil is injected into a factory production line is effectively avoided, the problem of oil pump ablation caused by the phenomenon is avoided, the service life of the electric fuel oil pump is prolonged, and meanwhile, a new thought is provided for the control method of the electric fuel oil pump.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of vehicle control, and in particular to a control method, device, electronic equipment and storage medium for an electric fuel pump. Background technique [0002] During the production and assembly process of the vehicle, it is necessary to electrify the vehicle to perform electronic and electrical inspection on the vehicle; and usually, the fuel tank is filled with fuel only after the electronic and electrical inspection is performed on the vehicle. [0003] However, as long as the vehicle is powered on, the controller controls the operation of the electric fuel pump; if there is no fuel in the fuel tank, the fuel pump will be in a dry running state, which will affect the service life of the fuel pump. Therefore, there is an urgent need for a new control logic of the electric fuel pump. Contents of the invention [0004] Embodiments of the present invention provide an electric ...
