According to the 6 * 4 plug-in type hybrid power tractor, a hybrid power system is formed by coupling three power schemes, the three power schemes can be independently controlled and can also be mutually standby power and auxiliary power under special working conditions, the safety of the whole tractor is improved, each path of the whole tractor control unit VCU can be independently controlled, and the whole tractor control efficiency is improved. The power state of each path can be calculated according to real-time road conditions, the optimal power scheme can be matched, compared with a conventional hybrid power system, the system has more power combination modes and can adapt to more complex use scenes, the optimal power matching scheme is achieved, powerful power of the whole vehicle is guaranteed through the three-path power system, and the service life of the whole vehicle is prolonged. In addition, the double-motor electric drive axle has high integration and strong power, a P2 power system composed of disc type motors and a chassis are more compact and scientific in arrangement space, an electric control oil pump, an air pump and a cab air conditioning system get rid of dependence on an engine, driving is quiet, and response is quicker.
