Abstract: A hybrid vehicle control unit (HV-ECU) sets a sub-battery voltage during an engine non-operation time to be lower than a sub-battery voltage during the normal time, which decreases a charge amount to the sub-battery relative to an amount during the normal time. The HV-ECU sets the sub-battery voltage during an engine operation time to be higher than the sub-battery voltage during the engine non-operation time, which increases the charge amount to the sub-battery relative to an amount during the engine non-operation time. An SOC control according to the above-described scheme prevents an SOC decrease of the sub-battery SOC in comparison to the conventional SOC control scheme, thereby preventing charging of the sub-battery when the main battery SOC is lower than a certain threshold. Therefore, a run-down of the sub-battery is prevented.

Abstract: When a request of a warming-up of a transmission is generated, a hybrid ECU sets a target input rotational speed of the transmission where a heat loss quantity of a MG becomes maximum, based on a request driving force of a vehicle. In this case, the heat loss quantity is a quantity of a heat loss causing an increasing of a temperature of an ATF in the MG. Thus, the hybrid ECU sets the target input rotational speed where the heat loss quantity becomes maximum and controls the transmission and the MG to output power that meets the request driving force of the vehicle. Since the hybrid ECU controls a torque of the MG, a torque of the engine, and a transmission ratio of the transmission to achieve the target input rotational speed, the hybrid ECU controls the MG, the engine, and the transmission in a condition that the heat loss quantity becomes maximum.
