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.

An ECU executes a program including the steps of: setting a target boost voltage to a maximum value when a request for changing a sub power supply is made; temporarily increasing discharge electric power of a main power supply and then restricting discharge electric power of the sub power supply before switching; shutting off a gate of a converter on the sub power supply side; performing processing for shutting off an SMR corresponding to the sub power supply before switching; connecting an SMR corresponding to a sub power supply after switching when an absolute value of a current is equal to or lower than a predetermined value; canceling shut-off of the gate of the converter on the sub power supply side; canceling temporary increase in discharge electric power of the main power supply and restriction of discharge electric power of the sub power supply; and canceling the setting of the maximum value as the target boost voltage.

A vehicle that is chargeable using power from an external power source includes: a chargeable electric storage device; a charging device that charges the electric storage device by using the power from the external power source; and a control device that, based on maximum supply power that is able to be supplied to the electric storage device and based on actual charge power actually supplied to the electric storage device, calculates a shortfall with respect to charge power supplied to the electric storage device in a case where charging is performed at the maximum supply power, and stores information relating to a causal factor for the shortfall.

Until a vehicle system is activated, a switching circuit outputs a pilot signal to an OR circuit. As a result, lowering of the potential of the pilot signal caused by a resistance circuit is avoided, and the pilot signal is provided in a non-pulsed manner. A power supply CPU is activated in accordance with any one of a connector signal and the non-pulsed pilot signal. When the vehicle system is activated, the switching circuit switches an output destination of the pilot signal to the resistance circuit.

An electrically-driven vehicle 10 comprises a chargeable and dischargeable battery 20, a charger 16 that charges the battery 20 using a supply of electric power from an external power supply 100, an accessory unit 19 that is driven by a supply of electric power from at least one of the battery 20 and the charger 16; and a PM-ECU 18 that controls drive of the charger 16 so that the charged amount of the battery does not exceed a predetermined charging upper limit. The PM-ECU 18 sets the charging upper limit used when the accessory unit 19 is being driven, lower than the charging upper limit used when the accessory unit 19 is not being driven in order to avoid overcharging when excessive electric power is supplied from the accessory unit 19 to the battery 20.

A boosting converter and a boosting control unit are mounted on a vehicle. A failure diagnosis unit makes a failure diagnosis of an atmospheric pressure sensor based on a detection result of the atmospheric pressure sensor and on a detection result of an intake pressure sensor detecting engine intake pressure that changes in accordance with a change in the atmospheric pressure. Boosting control unit controls an output voltage of the boosting converter based on the detection result of atmospheric pressure sensor and the detection result of intake pressure sensor.

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.
