Vehicle-mounted information-processing system, cloud service center and vehicle-mounted equipment

The invention discloses a vehicle-mounted information-processing system, a cloud service center and vehicle-mounted equipment. The vehicle-mounted information-processing system comprises the vehicle-mounted equipment, the cloud service center and a data center, wherein the vehicle-mounted equipment is used for sending a retrieval request with target information to the cloud service center; the cloud service center is used for retrieving target data matched with the target information from the data center after receiving the retrieval request, and then feeding back the matched target data as retrieval results of the retrieval request to the vehicle-mounted equipment, and in case the retrieval fails, the designations of the target data matched with the target information are obtained on the basis of the corresponding relation, the prompt information containing the designations is sent to the vehicle-mounted equipment; and the vehicle-mounted equipment receives the retrieval results or the prompt information. Due to the adoption of the technical scheme, the retrieval efficiency of the vehicle-mounted equipment is improved.
