Abstract:
1. A method for controlling a hybrid power system, the hybrid power system including an engine, a clutch, a transmission coupled to the engine, an electric motor, and an energy storage device coupled to the motor, the method comprising the steps of: setting a work mode based on a current vehicle velocity and a storage level of the energy storage device, wherein the work mode is set as an electric-only power mode or a parallel mode; if the work mode is set to the electric-only power mode, then assigning a power level such that an output power of the motor is based on the power demanded, and wherein the output power of the engine is 0; and if the work mode is set to the parallel mode, then assigning a power level such that an output power of the engine and an output power of the motor are both assigned based on a rotational speed of the engine.
