The method includes: obtaining a first vehicle speed measured by the speed measurement apparatus; obtaining reference information of a static reference object at N moments, where N is an integer greater than 1, and the reference information includes information about a location relationship of the static reference object relative to a vehicle in which the speed measurement apparatus is located at each of the N moments; calculating a second vehicle speed based on the reference information; and determining, based on the first vehicle speed and the second vehicle speed, whether the speed measurement apparatus is faulty.",
