A pedal box includes a housing, a drive rod, a pedal force feedback member, a pressure sensor, and a displacement sensor. The displacement sensor includes a moving component and a fixed component. The housing is configured to accommodate the moving component, the pedal force feedback member, and the pressure sensor. The pedal force feedback member and the pressure sensor are sequentially arranged inside the housing in an axial direction of the drive rod. The housing is further configured to fasten the fixed component. The moving component is disposed between the pedal force feedback member and the fixed component in a radial direction of the drive rod.
