HYBRID POWER SYSTEM, CONTROL METHOD, COMPUTER SYSTEM, PROGRAM PRODUCT, AND VEHICLE

Disclosed are a hybrid power system, a control method, a computer system, a program product, and a vehicle. The hybrid power system includes: an engine, a motor generator, a gearbox, a variable displacement hydraulic pump, and a battery electrically connected to the motor generator, where the gearbox includes a first transmission shaft, a second transmission shaft, a first gear disposed on the first transmission shaft, and a second gear disposed on the second transmission shaft, where the first gear is coupled to the second gear; a rotation shaft of the motor generator is coupled to one end of the second transmission shaft; and the engine is connected to the variable displacement hydraulic pump via the first transmission shaft through 1:1 transmission. The present disclosure can simplify the structure and control of the hybrid power system, improve fuel economy, and reduce costs.
