The invention provides a power-assisted steering device and a vehicle, and the power-assisted steering device mainly comprises an input shaft; the output shaft is connected with the input shaft; the first induction coil and the second induction coil are oppositely arranged on the outer side of the input shaft in a sleeving mode in the axial direction of the input shaft at intervals. The transmission part is connected with the input shaft, and part of the transmission part is arranged on an inner ring between the first induction coil and the second induction coil; the transmission part is configured to move in the axial direction of the input shaft and cut magnetic induction lines generated by the first induction coil or the second induction coil at the stage that the input shaft rotates in the control direction. The electromagnetic power assisting piece is arranged on the outer side of the output shaft in a sleeving mode; the controller is connected with the first induction coil and the second induction coil, receives magnetic field line signals controlled by the first induction coil and the second induction coil and controls the electromagnetic power assisting piece. According to the embodiment provided by the invention, the control direction and the rotation angle of the input shaft are determined by using the current data change generated by cutting the magnetic induction line generated by the first induction coil or the second induction coil by the moving part, so that the torque measurement accuracy is improved.
