A dual-motor hybrid power system for a vehicle comprises a first motor (1), a second motor (2), an engine (21), an intermediate shaft (13) and a first gear set (7, 14) disposed between a first driving shaft (3) and the intermediate shaft (13). The first driving shaft (3) continuously couples with the intermediate shaft (13) via the first gear set (7, 14), a second gear set (12, 15) disposed between a second driving shaft (4) and the intermediate shaft (13), and a single synchronizer (8) disposed around the second driving shaft (4), the engine (21) disposed to be coupled to the second driving shaft (4) via a clutch (23). The synchronizer (8) can be switched between a neutral position, a first-speed-ratio position, and a second-speed-ratio position. In the neutral position, the second driving shaft (4) is decoupled from the first and second gear sets. In the first-speed-ratio position, the synchronizer (8) couples the second driving shaft (4) with the intermediate shaft (13) via the first gear set (7, 4). In the second-speed-ratio position, the synchronizer (8) couples the second driving shaft (4) with the intermediate shaft (13) via the second gear set (12, 15).
