본 발명은, 제1 모터를 주행을 위한 구동력원으로 한 경우에 감속기로서 기능하는 동력 분할 기구의 내구성을 향상시키고, 또한 연비의 향상을 도모한다. 캐리어를 고정하여 제1 모터로부터 구동력을 동력 분할 기구에 입력하는 제1 구동 상태의 허가 및 금지를 제어하는 컨트롤러가, 제1 구동 상태가 종료되어 있는 시간을 카운트하고(스텝 S4), 그 카운트된 시간에 기초하여 동력 분할 기구에 대한 온도를 구하고(스텝 S13), 상기 구해진 온도가 미리 정한 허가 온도보다 낮은 경우에 제1 구동 상태를 허가하고(스텝 S15), 또한 상기 구해진 온도가 허가 온도 이상인 경우에 제1 구동 상태를 금지한다(스텝 S10).

    The present invention relates to a drive control system for preventing damage from a power distribution device (4) under a motor mode and for improving fuel efficiency. A time duration (Time_OFF) from termination of the first operating mode where a torque of the first motor (2) is applied to the power distribution device (4) while halting a carrier (8) (at step S4), and a temperature (Tp_est) of the power distribution device (4) is estimated based on the calculated time duration(Time_OFF) (at step S13). The first operating mode is enabled if the estimated temperature (Tp_est) is lower than a predetermined allowable temperature (Tpb) (at step S 15), and inhibited if the estimated temperature is higher than the allowable temperature (Tpb) (at step S10).
