Engine starting control method and control device

Abstract

The invention relates to the technical field of engines, in particular to an engine starting control method and control device, which aims to solve the technical problem that an engine is mistakenly started due to an interference signal before being autonomously started. The engine starting control method comprises the following steps of acquiring a current state of the engine; acquiring rotatingspeed signals of the engine according to the current state of the engine in combination with a starting machine; controlling the rotating speed signals so as to carry out filtering processing, and filtering out rotating speed signals with signal jumping in the rotating speed signals; and matching with an autonomous starting rotating speed signal according to the rotating speed signals subjected tofiltering processing, and controlling the engine and the starting machine offline so as to enter an autonomous operation state. According to the engine starting control method and control device, effective filtering processing is carried out aiming at large abnormal jumping appearing at instantaneous speed rotating before the engine is autonomously started, and the phenomenon that the engine is mistakenly started due to the disturbance of rotating speed fluctuation before being autonomously started can be reduced.

Description

technical field

[0001] The invention relates to the technical field of engines, in particular to a control method and a control device for starting an engine. Background technique

[0002] This section provides background information related to the present disclosure only and is not necessarily prior art.

[0003] The engine speed is a very important control parameter in the process of mechanical control. For example, the engine speed plays an important role in power control, engine start, and speed change control. Accurately and quickly collect engine speed signals and minimize interference signals. It is of great significance to further improve the response ability and stability of the control system, but in the process of starting the engine driven by the starter, the engine speed fluctuation is more obvious, and the existing technology does not do any processing on the collected engine speed signal , the engine speed collected by the starter during the starting process ...
