Zusammenfassung:	To provide a control system and a control method for a hybrid vehicle, which make it possible to cause the hybrid vehicle to efficiently travel to thereby make it possible to improve fuel economy. A control system 1 for a hybrid vehicle V includes an ECU 2. The ECU 2 calculates four total efficiencies TE_eng, TE_ch, TE_asst, and TE_ev, using energy ENE_eng2 transmitted from an internal combustion engine 3 to drive wheels DW during operation of the engine 3, energy ENE_mot2 transmitted from an electric motor 4 to the drive wheels DW during operation of the electric motor 4, energy ENE_mot2 charged when motive power of the engine 3 is converted to electric energy by a power generating operation of the electric motor 4 during the operation of the engine 3, and energy assumed to be supplied to whole motive power sources 3 and 4 (ENE_eng1, ENE_eng1 + ENE_mot1, ENE_mot1) (step 2), and selects a travel mode which makes it possible to obtain the highest value of the four total efficiencies TE_eng, TE_ch, TE_asst, and TE_ev according to required torque TRQ and vehicle speed VP (step 3).
