Abstract:
A power output apparatus mounted on a vehicle for outputting power to a drive shaft, said power output apparatus comprising:a motor for outputting power to said drive shaft;an engine to output mechanical power, said motor converting at least a portion of the mechanical power output by the engine to mechanical energy as the power output to the drive shaft;a generator for converting at least part of said mechanical power output from said engine to electrical energy, the generator regenerating a portion of the mechanical power output from the engine while the motor is outputting power to the drive shaft;accumulator means being charged with the electrical energy converted by said generator and being discharged to supply electrical energy required for driving said motor;state detection means for detecting a state of said accumulator means;driving condition predicting means for predicting a driving condition of said vehicle at various positions, including predicted positions, of a route;target state setting means for setting a target state of said accumulator means based on the predicted driving condition, said target state set at each of the various positions, including the predicted positions along the route while driving; andcharge-discharge control means for controlling said engine and said generator to enable the state of said accumulator means to become equal to said target state.
