摘要： In the vehicle of the invention, when the temperature of an inverter 42 for driving a motor MG2 linked to front wheels 62a and 62b reaches or exceeds a preset restriction start temperature, the drive control of the invention controls the inverters 42 and 43 to gradually decrease the output torque of the motor MG2 simultaneously with a gradual increase in output torque of a motor MG3, which is linked to rear wheels 64a and 64b. Such torque control ensures output of a torque demand required for the vehicle. When the temperature of the inverter 42 reaches or exceeds a preset frequency switchover temperature, which is higher than the restriction start temperature, the drive control of the invention controls the inverters 42 and 43 to lower a switching frequency of transistors T1 to T6 in the inverter 42 and to ensure output of the torque demand. Such drive control effectively relieves the load of the inverter 42, while decreasing the frequency of lowering the switching frequency of the inverter 42. This arrangement thus desirably attains both prevention of overheat of the inverter 42 and reduces the switching noise.

摘要： A current detection unit starts sampling of a motor current at the timing when the motor current has exceeded a threshold value, and holds a maximum motor current value for each prescribed operation cycle. An abnormality determination unit determines whether the maximum motor current value is greater than the threshold value, and counts the number of times that the maximum motor current value continuously exceeds the threshold value. When the count value has reached at least 3, the abnormality determination unit generates and outputs a detection signal indicating abnormality in the motor current to a relay drive unit and a notification unit. The relay drive unit in receipt of the detection signal generates a signal to turn off the system relays. The notification unit generates and outputs a signal AL to display means outside the power supply apparatus.
