DRIVE CONTROL SYSTEM FOR HYBRID VEHICLE

摘要

Even though an estimated value of a pinion temperature (Tp_est) reaches an upper limit temperature (Tp_th), a two-motor mode is allowed (at step S16) until duration of the time (Time_ON) reaches a reference time (τ_on) (at step S17). Moreover, even though the estimated value does not decline to an allowable temperature (Tpb) as the pinion temperature (Tp_est) declines, the two-motor mode is allowed at the time that duration (Time_OFF) of a state wherein the two-motor mode is not performed reaches a reference time (τ_off).
