The invention provides a hybrid electric driving device which comprises an engine, a first motor, a second motor, a front drive part, a first planet row, a second planet row and a gear shifting component. The engine is connected with the first planet row and the second planet row through the front drive part. The first motor is connected with the first planet row. The second planet row is connected with wheels through the second motor. The first planet row and the second planet row are in meshed transmission. The transmission ratio of the first planet row or the second planet row is fixed through the gear shifting component. According to the hybrid electric driving device, due to the arrangement of the front drive part, the two planet rows and the gear shifting component, the power dividing mode and the transmission ratio fixing mode can be achieved, and therefore the transmission efficiency can be improved while the dynamic performance is enhanced.
