<p>A control system and control method for a hybrid vehicle, which is capable of suppressing fuel consumption, thereby making it possible to improve fuel economy, when the hybrid vehicle is caused to travel using motive power of at least one of an electric motor and an internal combustion engine is provided. The control system 1 for the hybrid vehicle V, for controlling operations of the engine 3 and the electric motor 4 includes an ECU 2. During execution of an EV travel mode, the ECU 2 calculates an engine fuel consumption amount FC_eng and an EV fuel consumption amount FC_ev required when an engine travel mode and an EV travel mode are executed, respectively, according to required torque TRQ and vehicle speed VP (step 41). The ECU 2 selects and executes, when the engine fuel consumption amount FC_eng is smaller than the EV fuel consumption amount FC_ev, the engine travel mode, whereas when the EV fuel consumption amount FC_ev is smaller than the engine fuel consumption amount FC_eng, the EV travel mode (steps 42, 43).</p> |
