POWER OUTPUT APPARATUS, CONTROL METHOD OF POWER OUTPUT APPARATUS, AND VEHICLE EQUIPPED WITH POWER OUTPUT APPARATUS

摘要

The drive control of the invention executed in a vehicle sets a correction coefficient keg, based on an intake air temperature Ta and an atmospheric pressure Pa reflecting the density of intake air supplied to an engine (step S140), and multiplies a power demand P* required for the vehicle by the set correction coefficient keg to specify a target engine power Pe*, which is to be output from the engine (step S150). The engine and two motors MG1 and MG2 are then controlled to ensure output of the specified target engine power Pe* from the engine and output of a torque demand Tr*, which depends upon an accelerator opening Acc (steps S160 to S210). The varying density of the intake air may cause output of excessive power from the engine or output of insufficient power from the engine. A battery is charged or discharged to compensate for the excessive power output from the engine or for the insufficient power output from the engine. The drive control of the invention effectively deals with the environmental change and prevents the battery from being excessively charged with an unexpectedly high electric power or from being excessively discharged to supply an unexpectedly high electric power.
