At present, there is a lack of management and layout design for the parking device of small vehicle which refers to E-bike, bike and motorbike, etc. We designed a new type of automated small vehicle stereo parking device, which is driven by microcomputer and stepper motors. It realizes vehicle access and management through automatic control. Intelligent vehicle management can effectively solve the problem of irregular parking at present and have the advantage of a higher rate of space utilization. It is suitable for the place where the land is limited. The actual area used are less than 3 square meters per device, but has the storage of at least 24 small vehicles.
