To provide a vehicle speed detection method, vehicle speed detection unit and self-driving device that can detect a vehicle speed in high responsiveness without giving any act of working to wheels.SOLUTION: A vehicle speed detection method is configured to: measure an input signal Ia to a resolver 3A of a motor 3 boarded on a vehicle 2, and an output signal Ii from the resolver; detect a rotation angle θ of the motor 3 from a relation between the input signal Ia and the output signal Ii; and compute a movement speed S of the vehicle 2 using the rotation angle θ.SELECTED DRAWING: Figure 1
【課題】 ホイールに細工を施すことなく車速を高い応答性で検出することができる車両の速度検知方法、車速検知ユニットおよび自動運転装置を提供する。【解決手段】車両２に搭載されたモータ３のレゾルバ３Ａへの入力信号Ｉａとレゾルバからの出力信号Ｉｉを測定し、前記入力信号Ｉａと出力信号Ｉｉの関係からモータ３の回転角θを検出し、この回転角θを用いて車両２の移動速度Ｓを演算する。【選択図】図１
