摘要： PROBLEM TO BE SOLVED: To provide an escape operation where running performances geared to the needs of a user are switched, in an electric vehicle mounting a power system where plural sets of condensers and converters are connected in parallel. SOLUTION: An escape run controller 115 determines whether a normal converter capable of usual power converting action is existing, based on fault information, at the time of escape run. The normal converter is directed to execute the voltage control according to the target voltage VR. A VR setter 120 selects either a mode of setting the target voltage VR so that it inhibits the boosting operation by the normal converter or a mode of setting the target voltage VR suitable for the present state (the target value of torque and the target value of rotational speed) of a motor generator by permitting the boosting action by the converter, based on the vehicle state of an electric vehicle, thereby setting the target voltage VR.

摘要： PROBLEM TO BE SOLVED: To make a more proper determination on abnormality such as the deterioration of insulation at a midpoint of a battery pack.SOLUTION: A power supply unit comprises: a battery pack 22; a potential sensor 56 for detecting a potential V3 at a midpoint 23 of the battery pack 22 with respect to the ground; potential sensors 52 and 54; and a system main relay 28 including a positive-electrode side relay SB and a negative-electrode side relay SG. In the power supply unit, whether or not an abnormal insulation occurs is determined based on whether or not the potential V3 detected by the potential sensor 56 falls within a predetermined normal range with only one of the positive-electrode side relay SB and the negative-electrode side relay SG put in ON state. In this way, a more proper determination can be made on an abnormal insulation such as the deterioration of insulation on the positive-electrode side of the midpoint 23 of the battery pack 22, and an abnormal insulation such as the deterioration on the negative-electrode side of the midpoint 23 of the battery pack 22. In addition, whether or not an abnormal insulation occurs is determined based on whether or not the ratio of the absolute values of potentials V1 and V2 provided from the potential sensors 52 and 54 falls within a predetermined normal range with both of the positive-electrode side relay SB and the negative-electrode side relay SG of the system main relay 28 put in ON states.

The electric vehicle also includes: detecting the deterioration of insulation resistances of the electrical system, in accordance with respective states of an inverter to drive a drive motor, an inverter for air conditioning, and a system main relay; and executing a motor area determination step, an air conditioning area determination step, and a battery area determination step (S240, S280, S320) so that a region where the insulation resistance is deteriorated is specified from among three regions of a motor area, an air conditioning area, and a battery area, after it is detected that the insulation resistance of the system is deteriorated. When the region where the insulation resistance is deteriorated cannot be specified even by executing such determination steps, after the system is started subsequently, determination steps of the respective areas are executed again so as to specify the region where the insulation resistance is deteriorated for a region which causes impossibility of the designation.

摘要： PROBLEM TO BE SOLVED: To certainly prevent the movement of an electric vehicle from where it is parked when the gear shifts into other range than the parking range by erroneous operation while it is charged from outside. SOLUTION: When a lock control section 500 detects that the P range is non-selected while a charging cable is connected for charging an electric storage device from outside, the lock control section 500 generates a lock instruction signal dLCK to a motor control section 530. When the lock instruction signal dLCK is generated, the motor control section 530 generates an inverter control instruction for a second inverter which performs power conversion between the electric storage device and a second MG, which is a motor for driving the vehicle, so that such a current as to fix the rotation of the output shaft of the second MG may be supplied to the second MG.
