A power control device that controls electric power supplied from an external power supply to a vehicle includes: a switching unit that switches a supply voltage value of the external power supply; and a control unit that generates a signal, indicating an allowable current value of the external power supply, to transmit the signal to the vehicle, and that controls the switching unit to thereby control the supply voltage value, wherein the control unit changes the signal and the supply voltage value on the basis of a given electric power command value.

A first motor generator-control unit (MG1-ECU) and a second motor generator-control unit (MG2-ECU) are provided independently for respective motor generators. The MG2-ECU performs electric power balance control by correcting an MG2 torque command value as required, so that the sum of the MG1 electric power and the MG2 electric power is within a range of allowable input / output electric power of a DC power supply. The electric power balance control is performed using an estimate of the MG1 electric power based on data obtained by the MG1-ECU. The estimate is determined so that a communication delay time between the MG1-ECU and the MG2-ECU is corrected. In this way, the electric power balance control can be performed appropriately for restricting, within a predetermined range, the total input / output electric power of the electric motors as a whole of a hybrid vehicle mounted with a plurality of motor generators (electric motors).

The plurality of parameters include a first voltage which is applied between two terminals of the battery cell, a second voltage which specifies a no-load voltage of the battery cell, and a time variable.

A vehicle controller is configured to execute a duty cycle control process of alternately repeating an electric power generation execution period and an electric power generation stop period of an electric generator and controlling a duty cycle, which is a ratio of the electric power generation execution period to a single cycle of repeated cycles, when determining that an anomaly has occurred in a driving circuit. The duty cycle control process includes at least one of two processes, a process of setting the duty cycle to be larger when a member in an overheatable region, in which overheating is possibly performed by the heater, has a low temperature than when the member has a high temperature and a process of setting the duty cycle to be larger when an internal combustion engine has a large intake air amount than when the engine has a small intake air amount.
