摘要： A second power storage device is electrically connected to a positive electrode line and a negative electrode line, and electric power for generating a driving force is directly supplied to an inverter section. A converter section supplies electric power received from the inverter section to a first power storage device. Because a backflow prevention circuit is provided, the electric power is not supplied in the direction of the second power storage device at this point. A diode of the backflow prevention circuit is connected between a system main relay and the connection node of a positive electrode line on the positive electrode line branching off from the positive electrode line and connected to the second power storage device. The diode controls the flow of a current from the positive electrode line side toward the second power storage device.

摘要： A power supply system has a power storage device and an ECU, and supplies driving electric power to a load device. The power storage device includes an interrupting device configured to interrupt a conduction path of the power storage device. The load device includes a voltage sensor for detecting a voltage applied to the load device, and supply of electric power from the load device to the power storage device is stopped in response to a failure of the voltage sensor. Where the voltage sensor has failed, the ECU determines presence or absence of activation of the interrupting device, based on a variation length of an actual current that is input to or output from the power storage device and a variation length of a command current set in accordance with requested electric power requested based on a user's operation.

摘要： An electric power supply system for supplying a load device with driving electric power includes an electric power storage device and an ECU. The electric power storage device includes a CID configured to interrupt an electrical conduction path of the electric power storage device in response to the electric power storage device having an internal pressure exceeding a rated value. The controller calculates a voltage variation length corresponding to an integral of an amount by which a voltage applied to the load device varies in magnitude and a current variation length corresponding to an integral of an amount by which a current input/output to/from the electric power storage device varies in magnitude for each sampling period for a predetermined period of time. Then, the ECU determines whether or not the CID has been operated, based on the voltage variation length and the current variation length.

摘要： A vehicle includes: a power storage device; a charging device that receives electric power from outside the vehicle and charges the power storage device; an auxiliary device that receives the electric power from the power storage device or from outside the vehicle; and a control device. When there is a request for operating the auxiliary device during execution of charging of the power storage device by the charging device, the control device continues operation of the auxiliary device even if input of the electric power from outside is discontinued. When there is no request for operating the auxiliary device during execution of charging of the power storage device by the charging device, the control device separates the power storage device from the charging device and the auxiliary device in response to discontinuation of input of the electric power from outside.

摘要： A shift position of an electric powered vehicle is selected by operating a shift lever and a P position switch. A power source position is selected by operating a power switch. When any of switching elements forming an inverter device is short-circuited, selection of the shift position and the power source position is controlled such that simultaneous selection of a power source position at which inverter control is turned off and a shift position at which a parking lock mechanism is inactivated can be avoided. Therefore, inverter control for reducing short-circuit current caused by back electromotive force derived from rotation of a motor generator after occurrence of short-circuit failure can reliably be executed.

摘要： When such a failure as the output from a voltage sensor becomes unavailable is detected, a controller controls a connecting section to disconnected state and controls a voltage converter to voltage unconverted state so that the voltage of a positive pole bus is outputted to the terminal of the voltage converter on the connecting section side, and performs voltage control of the positive pole bus based on the output from a voltage sensor in place of the output from the voltage sensor. Consequently, a power supply unit for a vehicle which can perform escape running while maintaining the traveling performance as much as possible even upon occurrence of failure in the sensor is provided.

摘要： Upon the occurrence of the abnormality that the inverter for driving the motor is in the one-phase short circuited state, this inverter is stopped in the three-phase short circuited state and sets the execution torque by subtracting the counter electromotive force application torque that is applied the driveshaft due to the counter electromotive force generated by rotation of the motor and the steering angle application torque corresponding to the steering angle from the torque demand according to the step-on amount of the accelerator pedal. The engine and the inverter for driving the motor is controlled so that the vehicle is driven with the set execution torque. This enables the driving force output to the driveshaft from the engine and the motor to be in accordance with the torque demand.

摘要： An air-fuel ratio control apparatus for an internal combustion engine, implementing integral correction of the air-fuel ratio by an integral term edfii obtained by multiplying an integrated difference between a target air fuel ratio and the actual air-fuel ratio by an integral gain, wherein the upper and lower limit values of the integral term are set based on the actual intake air amount and the actual air-fuel ratio. This limits the range of the integral term edfii to prevent it from being set at an excessively high or low level removed from the realities of the intake air amount and the air-fuel ratio, and thereby to prevent erroneous air-fuel ratio correction by the integral term.

摘要： Gas containing fuel vapor is purged as purge gas from a canister to an intake passage through a purge line. An ECU computes purge flow rate, which is the flow rate of the purge gas, and computes vapor concentration, which is the concentration of the fuel vapor contained in the purge gas. The ECU obtains a concentration correction value in accordance with the rate of change of the computed purge flow rate. The ECU correct the computed vapor concentration by using the concentration correction value and by taking into consideration of the time at which the purge flow rate is computed and the time at which purge gas having the computed flow rate is drawn into the combustion chamber. The ECU sets the fuel supply amount in accordance with the computed purge flow rate and the corrected vapor concentration. As a result, the accuracy of the air-fuel ratio control during purging is improved.
