The invention discloses a synchronization system and a synchronization method of an automatic driving system, the synchronization system comprises a V2X device, a domain controller device and a high-precision RTK device, the synchronization system also comprises a time positioning synchronization unit, the time positioning synchronization unit is used for receiving a 1PPS second pulse signal and position information sent by the high-precision RTK device; and the time positioning synchronization unit is also used for outputting the fused position information and the simulated 1PPS signal to the V2X equipment and the domain controller equipment when the working environment of the automatic driving system does not meet the preset condition. According to the invention, when the vehicle carrying the automatic driving system runs to the area with the weak GPS signal, the time position synchronization signal can still keep high precision, the normal work of the V2X equipment and the domain controller equipment is ensured, in addition, the use of an antenna can be reduced, and the equipment installation is facilitated.
