摘要:
An HV_ECU executes a program including the steps of: determining whether or not an EV switch is turned on until a monitoring timer expires (S300) when a system startup switch is turned on (YES in S100), latching the ON state of the EV switch if the EV switch is turned on and confirming an EV mode request on system startup (S400, S500), detecting various state quantities of a vehicle (S600), and starting up a system in an EV mode without starting an engine (S800) if an EV mode prohibiting condition is unsatisfied (YES in S700).

摘要:
When there is no malfunction in either drive shaft rotational speed detection portion (36) or rotating shaft rotational speed detection portion (44), control of internal combustion engine (22), the power split device (30, MG1), the electric motor (MG2), and the shifting portion (60) is performed while speed ratio in shifting portion (60) is changed and an intermittent operation of internal combustion engine (22) is performed so that a drive power required for drive shaft (32a) is output to shaft (32a). When a malfunction occurs in drive shaft rotational speed detection portion (36) or/and rotating shaft rotational speed detection portion (44), the control is performed while at least one of change in speed ratio, intermittent operation, and output of drive power required for shaft (32a) to shaft (32a) is limited so that a drive power that approximates required drive power as closely as possible is output to drive shaft (32a).
