Abstract

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 (1), a motor generator (2), a gearbox (3), a variable displacement hydraulic pump (4), and a battery (5) electrically connected to the motor generator (2), where the gearbox (3) includes a first transmission shaft (6), a second transmission shaft (7), a first gear (8) disposed on the first transmission shaft (6), and a second gear (9) disposed on the second transmission shaft (7), where the first gear (8) is coupled to the second gear (9); a rotation shaft of the motor generator (2) is coupled to one end of the second transmission shaft (7); and the engine (1) is connected to the variable displacement hydraulic pump (4) via the first transmission shaft (6) through 1:1 transmission. The present disclosure can simplify the structure and control of the hybrid power system, improve fuel economy, and reduce costs.
