The invention discloses a synchronizer-free clutch-free hybrid power transmission and a control method. The hybrid power transmission comprises an engine, a motor, a transmission mechanism, a main speed reducer and a differential mechanism assembly. The transmission mechanism comprises an engine input shaft, a gear connected with the engine input shaft in a sleeved mode, a gear shifting sliding sleeve and a fixed gear ring. The gear, the gear shifting sliding sleeve and the fixed gear ring are connected with the motor input shaft in a sleeved mode. The gear, the gear shifting sliding sleeve and the fixed gear ring are connected with the power output shaft in a sleeved mode. According to the hybrid power transmission, a clutch and a synchronizer are removed, the structure of the transmission is simplified, and the production and maintenance cost is reduced. In the gear shifting process, gear shifting impact is reduced through active synchronous speed regulation of the motor, and comfort is improved. Different gears and working modes are formed by controlling the position change and combination of the sliding sleeve, so that the fuel economy and the dynamic property of the vehicle are effectively improved.
