An electric power steering system (1) includes short-circuit determination means (31) for determining whether a short-circuit between an energization failure phase and one of the two phases other than the energization failure phase has occurred while assist force is being generated using the two phases other than the energization failure phase as energization phases. When the short-circuit determination means (31) determines that the short-circuit has occurred, generation of the assist force is stopped. |
