Abstract: Disclosed are a dual-motor multi-gear hybrid transmission system and a vehicle. The dual-motor multi-gear hybrid transmission system includes an engine, a first motor, a second motor, a first clutch, a second clutch, a first planet row, a second planet row, a first input shaft, a second input shaft, a third input shaft and a brake assembly. The first input shaft is connected to the engine through the first clutch. The second input shaft is connected to the engine through the second clutch, and the second input shaft is sleeved outside the first input shaft. The first motor is connected to the engine. The second motor is connected to the first planet row through the third input shaft. The brake assembly is configured to brake the first planet row and/or the second planet row.

Abstract: Systems and methods for synchronizing verification data in a distributed database including client and server databases. The server database may exchange verification data regarding one-time passwords to multiple client databases. An update to the server database may be initiated based on information stored in the client database by pushing updated verification information from the client database to the server database via an SSL tunnel. An update to the client database may be initiated based on information stored in the server database by pulling updated verification data from the server database to the client database via an SSL tunnel. The client database and the server database may include a two-dimensional data field including the verification data and an associated key identifier, and a site ID. The site ID may include a unique identifier to identify the respective database in which it is included.
