電動パワーステアリング装置
Document Type and Number:
Japanese Patent JP4228237
Kind Code:
B2
Abstract:
An electric power steering apparatus includes an electric power supply device that includes a main electric power unit that supplies high-tension electric power and a sub-electric power supply unit that supplies low-tension electric power, the main electric power unit and the sub-electric power supply unit being connected to each other in parallel, and that supplies electric power to the electric motor from one of the main electric power supply unit and the sub-electric power supply unit. An assist ECU calculates a correction coefficient based on which a d-axis target current increases with a decrease in voltage output from the electric power supply device, and calculates a final corrected d-axis target current by multiplying the d-axis target current by the correction coefficient.
