The invention relates to a dual-motor hybrid power speed change system and a vehicle, and the dual-motor hybrid power speed change system comprises a speed changer, an engine and two motors; the transmission comprises a variable-speed input shaft, two intermediate shafts, a variable-speed output shaft, a front auxiliary box transmission unit and a main box transmission unit. The front auxiliary box transmission unit is sleeved on the variable speed input shaft; the middle shafts are parallel to the axis of the variable-speed input shaft, and the two middle shafts are arranged on the two sides of the variable-speed input shaft; the front auxiliary box transmission unit is fixedly connected with each intermediate shaft; the axes of the variable-speed output shaft and the variable-speed input shaft coincide; the main box transmission unit is fixedly connected with each intermediate shaft, and the main box transmission unit is sleeved on the variable speed output shaft; the output end of the engine is connected with the variable-speed input shaft; the output end of the motor is connected with the intermediate shaft; driving force provided by the engine is dynamically coupled on the variable-speed output shaft through the variable-speed input shaft via the intermediate shaft, and/or driving force provided by the two motors is dynamically coupled on the variable-speed output shaft through the intermediate shaft.
