Abstract

The invention provides a vehicle oil way exhaust starting method and device and a storage medium, and the method comprises the steps: recognizing whether a current vehicle is in a first starting state or a conventional starting state according to a starting command of the current vehicle; if yes, executing a first starting mode; if yes, a second starting mode is executed; and exhaust starting is completed. Wherein the step of executing the first starting mode comprises the steps that through motor dragging, the rotating speed of an engine is increased to be higher than a first preset rotating speed, and the engine begins to fall back; and when the rotating speed of the engine falls back to the second preset rotating speed, the engine maintains the second preset rotating speed to run for set time, and power transmission between the motor and the engine is cut off. By means of the scheme, the problems that when the vehicle is started, air exists in a fuel oil pipeline, and the fuel injection quantity is not easy to control, so that the vehicle fails to start and even submerges a cylinder are solved.

Description

technical field [0001] The present application relates to the technical field of vehicle starting, and in particular to a method, device and storage medium for starting a vehicle with exhaust gas from an oil circuit. Background technique [0002] When conventional vehicles are produced and assembled on the production line, the oil supply pipeline of the engine is not filled with fuel. Therefore, when the vehicle is started for the first time off the production line, when the fuel injector is opened according to the normal opening pulse width, the part injected into the engine cylinder is The mixture of air or oil and gas may cause the actual fuel injection quantity to be less than the target fuel injection quantity, and the engine cannot be ignited if the mixture is too thin, and finally the engine is difficult to start or even fails to start. [0003] In order to solve this problem, the current mainstream vehicle off-line exhaust strategy is that the engine controller recog...
