Hybrid drive device and vehicle

The invention relates to a hybrid drive device and a vehicle. The hybrid drive device comprises an engine, a generator, a driving motor, a planetary gear mechanism, a first brake, a second brake, an intermediate shaft and an overrunning clutch, and an output shaft of the engine is connected with a planet carrier; an output shaft of the generator is connected with a sun gear and is also connected with the second brake; a gear ring is connected with the intermediate shaft through the overrunning clutch and is also connected with the first brake; the driving motor is connected with the intermediate shaft; the intermediate shaft outputs power to wheels. Multiple driving modes can be achieved, higher transmission efficiency is obtained, the gear ring and the intermediate shaft are connected through the overrunning clutch, decoupling of the engine and the wheels can be achieved, and following of the gear ring and the planet wheel when the driving motor drives the wheels to rotate is avoided.Therefore, the maximum v
