Abstract
An inverter energy consumption calculating portion estimates the actual power consumption of a steering operation assist motor after an engine is placed in an idle-stop state, and a command value of current to be supplied to the steering operation assist motor is limited such that the command value is smaller as the energy consumption is larger. The inverter energy consumption calculating portion calculates the energy consumption of an inverter drive circuit by integrating an amount of electric power consumed by the drive circuit.
