Title:
電動パワーステアリング装置
Document Type and Number:
Japanese Patent JP4501599
Kind Code:
B2
Abstract:
An electric power steering apparatus is described which comprises a booster circuit outputting an output voltage which is obtained by boosting a power supply voltage. A motor is controlled according to power that is supplied based on the output voltage of the booster circuit, the motor serving as a driving source to apply assisting force to a steering system. A control section controls the output voltage of the booster circuit through a feedback control based on a deviation of the output voltage from a target voltage, wherein, when application of assisting force to the steering system is stopped, the control section corrects the target voltage such that the target voltage is gradually lowered as time elapses from when the application of the assisting force is stopped.
