Special vehicle chassis and vehicle controlling method of hybrid power transmission system

The invention discloses a special vehicle chassis and a vehicle controlling method of a hybrid power transmission system. The special vehicle chassis of the hybrid power transmission system comprises a conventional running system, a loading operating system and a controlling system. The output end of the controlling system is connected with the input end of the conventional running system and the input end of the loading operating system, and the input end of the controlling system is connected with a selective switch. The conventional running system and the loading operating system are both powered by an engine. Compared with the prior art, the special vehicle chassis and the vehicle controlling method of the hybrid power transmission system meet the high-speed operating requirement of normal running of a vehicle, and low vehicle speed and infinitely variable speed requirements under the loading operation, operation is simple during switching, burden of a driver is reduced, and the price is reasonable. 本发明公开
