The invention discloses a center steering active wheel speed and steering angle measuring device and a deviation compensation method, and relates to the technical field of vehicle control, and the center steering active wheel speed and steering angle measuring device comprises a movable platform, a static platform, a rotation transmission mechanism, a steering transmission mechanism, a differential mechanism and a pair of rotary encoders, the rotation transmission mechanism and the steering transmission mechanism decouple rotation and steering actions of the driving wheel respectively and then transmit the decoupled rotation and steering actions to the pair of rotary encoders, so that combined measurement of the actual wheel speed and the actual steering angle of the driving wheel is achieved. According to the invention, the steering transmission mechanism and the rotation transmission mechanism are mainly utilized to realize decoupling of steering and rotation motion of the driving wheel from the structure,
