In a control system for a hybrid vehicle including an engine (2), a motor-generator (MG1), a power distribution/integration mechanism (3) having three rotary elements (31, 32, 33) connected to a crankshaft (27), a rotary shaft (36) of the motor-generator (MG1), and a ring gear shaft (32a), a motor-generator (MG2), and a battery (80), a battery ECU (400) sets a required charging power (Pchg) to a required charging power (Pchg-α) that is lower than a normally set required charging power (Pchg-&bgr;), under a condition that the vehicle speed (V) is lower than a given speed (V1), so that torque fluctuation of the engine (2) is absorbed by hysteresis torque generated by a hysteresis mechanism (70). |
