A device for extracting operation information about a connected car is proposed. The device may include an outlier remover removing outliers from speed data in which the speed of a vehicle is measured at every predetermined time interval and stored, and from accumulated travel section data in which the section traveled by the vehicle is accumulatively stored at every predetermined time interval; The device may also include a travel section extractor extracting the section in which the vehicle has traveled, based on the speed data and the accumulated travel section data from which the outliers were removed. The device may further include a stop section extractor extracting a stop section in which the vehicle has stopped; and a pure travel section extractor extracting, as a pure travel section, a section in which the stop section present in the travel section is excluded from the travel section.

Device for extracting operation information about connected car on basis of onboard diagnostic data, and method therefor

The present disclosure provides a connected car big data acquisition device, and connected car big data collecting system and method using the device. A connected car big data acquisition device includes: an interface configured to communicate with a device associated with a data production layer and a device associated with a service using layer; a storage configured to store data; and a controller configured to generate preprocessed data based on raw data related to connected cars received from a device associated with a data production layer through a preprocessing process using an integrated platform and to control the preprocessed data to be stored in the storage based on a memory availability ratio of the storage.
