The invention relates to a vehicle direct drive and hybrid power transmission system. The vehicle direct drive and hybrid power transmission system comprises an engine, a first motor, a second motor, a planetary gear mechanism, a clutch, a reduction gear set and a battery device. The engine is coaxially connected with a planet carrier of the planetary gear mechanism, the first motor is coaxially connected with a sun gear of the planetary gear mechanism, a gear ring of the planetary gear mechanism transmits power to a vehicle driving wheel shaft, and the second motor transmits power to the vehicle driving wheel shaft through the reduction gear set. A sun gear of the planetary gear mechanism and a gear ring of the planetary gear mechanism rotate at a fixed speed ratio through a clutch; and the battery device is charged and discharged with the first motor and the second motor. And a planet carrier of the planetary gear mechanism is provided with a locking device. The hybrid power transmission system adopting the structure has good power performance and fuel efficiency during full-speed range driving, and is simple and reliable in structure.
