Method and device for controlling cylinder deactivation position of engine, electronic equipment and storage medium

Abstract

The embodiment of the invention discloses a method and device for controlling the cylinder deactivation position of an engine, electronic equipment and a storage medium, and the method comprises the steps that under the condition that it is detected that the engine has the cylinder deactivation requirement, the rotating speed of the engine is obtained; controlling the rotating speed of the engine, and obtaining a rotating speed control result; according to the rotating speed control result, the engine position signal and the motor rotary transformer signal are synchronized, and a synchronization result is obtained; and under the condition that the synchronization result is successful synchronization, the position of the motor is controlled, so that the engine stops in a preset crank angle interval. Therefore, even if one or two engine position signals have faults, the position control of the engine can be realized, and the stability when the cylinder deactivation position of the engine is controlled is ensured; meanwhile, by controlling the engine to stop in the preset crank angle interval, the problem that the cylinder deactivation position of the engine is random can be avoided, and the smoothness of the engine is improved.
