Engine start suppression for a hybrid car
Abstract:
During EV traveling in a CD mode, an electronic control unit determine that an engine is in a state where the engine is likely to be started when an electric power storage ratio SOC of a battery falls short of a threshold Sref, when a battery temperature Tb of the battery falls short of a threshold Tbref, when an output limit Wout of the battery falls short of a threshold Wref, when a temperature Tmg2 of a motor is higher than a threshold Tmg2ref, and when a torque limit Tm2lim of the motor falls short of a threshold Tm2limref. Then, the electronic control unit set a required torque Tr* by using a map for a CS mode in which the required torque Tr* is set to be lower than in a map for the CD mode.
