Detection method and device for initial position of sliding sleeve, electronic equipment and storage medium

The invention discloses a sliding sleeve initial position detection method and device, electronic equipment and a storage medium. The invention relates to the technical field of vehicle control. The method comprises the steps that the initial position of a sliding sleeve and operation parameters of a valve lift switching system are determined; when the operation parameters meet the pin stretching condition, the pin is controlled to stretch out, and the stretching position of the pin is obtained; an initial position is detected based on the extended position, a reference position of the pin, and a preset position threshold. According to the technical scheme, when the operation parameters of the valve lift switching system meet the pin stretching condition, the pin is controlled to stretch out, and the initial position of the sliding sleeve is detected according to the stretching position of the pin, the reference position and the preset position threshold value; the initial position of the sliding sleeve of th
