    Abstract: PROBLEM TO BE SOLVED: To provide a method for determining abnormality of a booster circuit or a relay connected to a battery, wherein abnormality occurs in monitoring, without having to provide a special sensor, when cutting off the battery wherein the abnormality occurs in the monitoring and performing standby traveling. SOLUTION: When standby travel is conducted, by reaching a state of not monitoring a slave battery by the occurrence of abnormality in an electronic control unit for the slave battery, an intermediate voltage between a high-voltage-system target voltage VH* and a first low-voltage-system voltage VL* is set as a threshold voltage Vset (S110). When a second low-voltage-system voltage VL2 is larger than the threshold voltage Vset, over a prescribed period or when a high-voltage-system voltage VH is less than the threshold voltage Vset over a prescribed period, it is decided that there is an abnormality by on-fixing occurring, in the slave side booster circuit 65 or in system main relays 66, 67 (S140).

    Abstract: PROBLEM TO BE SOLVED: To prevent the shortage of a torque to a driving shaft due to the impossibility of the start of an engine. SOLUTION: In an automobile where an engine and a motor MG1 and a driving shaft connected to a driving wheel are connected to a planetary gear mechanism, and a motor MG2 is connected through a transmission to the driving shaft, even when a request power Pe* is a threshold Pref or less, and when a motor temperature θm1 as the temperature of the motor MG1 is a threshold θref or more (S120, S240), an idle operation is performed without stopping the engine (S250). Thus, when a relatively large torque is requested to the driving shaft, it is possible to prevent the torque shortage to the driving shaft due to the impossibility of the motoring of the engine by the motor MG1, and the impossibility of the start of the engine.

    Abstract: PROBLEM TO BE SOLVED: To appropriately respond to the shift operation to a P (parking) position.SOLUTION: An operation determination time Tonset which is a period until presence of a shift change request is determined while a shift operation to the P position is detected, is set to a first time T1 (S130), when the absolute value of a gradient θ is smaller than a slope determination threshold θref, and is set to a second time T2 shorter than the first time T1 (S140) when the absolute value of the gradient θ is equal to or larger than the slope determination threshold θref, when the absolute value of a vehicle speed V is equal to or lower than a vehicle stop determination threshold Vref. Thereby, occurrence of inconvenience such that a vehicle creeps downward in a climbing lane or a descending lane can be suppressed. Further, the operation determination time Tonset is set to a third time T3 longer than the first time T1 (S150) when the absolute value of a vehicle speed V is larger than the vehicle stop determination threshold Vref. Thus, occurrence of inconvenience caused by inhibition of a shift change to the P position by the erroneous operation of a driver or the erroneous detection by a sensor during running, can be suppressed.
