PROBLEM TO BE SOLVED: To provide an electric power steering device capable of calmly dealing with a situation during burst of a wheel.SOLUTION: An emergency control section 40 has a function for calculating a yaw rate deviation to be a difference between a target yaw rate and a detected yaw rate detected in a yaw rate detection device, generating steering torque gain when steering torque is equal to or less than a maximum set value, generating air pressure gain when air pressure is equal to or less than a maximum set value, and calculating an auxiliary control signal by multiplying the yaw rate deviation by the steering torque gain and the air pressure gain. A basic control section 50 includes a steering characteristic storage section 51 for storing assist torque in accordance with vehicle speed and the steering torque, and an addition section 52 for adding the auxiliary control signal of the emergency control section 40 to a base steering characteristic stored in the steering characteristic storage section 51 and outputting the added base steering characteristic to a driving device 29.

    【課題】車輪のバースト時に冷静に対処できる電動パワーステアリング装置を提供する。【解決手段】緊急制御部40は、目標ヨーレイトと、ヨーレイト検出装置で検出された検出ヨーレイトとの差であるヨーレイト偏差を算出し、操舵トルクが最大設定値以下のときに操舵トルクゲインを発生させ、空気圧が最大設定値以下のときに空気圧ゲインを発生させ、ヨーレイト偏差に操舵トルクゲインおよび空気圧ゲインを乗算することによって補助制御信号を算出する機能を有し、基本制御部50は、車速、操舵トルクに応じたアシストトルクを記憶する操舵特性記憶部51と、操舵特性記憶部51に記憶されたベース操舵特性に緊急制御部40の補助制御信号を加算し、駆動装置29に出力する加算部52とを備えた。【選択図】図2
