Claim One:
1. A vehicle hybrid power system, which comprises: a battery, which is for providing electrical power; a motor, which is driven by the electrical power provided by the battery; an engine, which is driven by burning fuel; a generator, which is driven by the engine to generate electricity, the generator being for charging the battery; a clutch, which is for engaging or disengaging the motor and the engine such that they either separately or jointly power the vehicle; a power output unit, which is for outputting power provided by the engine and the motor; a memory unit, which is for saving simulated equivalent fuel consumption multi-dimensional data obtained via minimum and maximum physical allowed values of system control parameters, system state parameters, and system negative load parameters; a system parameter detection unit, which is for detecting system state parameters and system negative load parameters; and a vehicle control unit, which is loaded with parameters detected by the system parameter detection unit, and, based on input system state parameters and system negative load parameters, acquires minimum simulated equivalent fuel consumption and its corresponding system control parameters from the simulated equivalent fuel consumption multidimensional data saved in the memory unit, and then accordingly separately controls the actions of the engine, the motor, the clutch, and the generator based on the acquired system control parameters.
