ABSTRACT:
A hybrid vehicle comprises an engine2, a motor generator4, a torque converter6with a lock-up clutch5, and a ratio-change mechanism7. A control system for the hybrid vehicle comprises a rotational sensor22, which detects the slip ratio of the torque converter, and a hydraulic control valve12, which controls the engagement of the lock-up clutch. While the vehicle is moving along with the accelerator pedal being released from its stepped down condition, a driving force from the wheels is transmitted to the motor generator4for energy regeneration. If the slip ratio of the torque converter is equal to or smaller than a first threshold value, then only the lock-up clutch is controlled into engagement. However, if the slip ratio is between the first threshold value and a second threshold value, then additionally the motor generator is controlled in cooperative operation.
