1. A steering control method for a redundant steering system, said method comprising:
receiving, by a first steering controller and a second steering controller, a first command signal and a second command signal, respectively; and
synchronizing control outputs of the first steering controller and the second steering controller such that at least one of the first steering controller and the second steering controller compensates a control timing according to the first command signal and the second command signal so that the control outputs are synchronized,
wherein, during synchronizing of the control outputs of the first steering controller and the second steering controller, the first steering controller and the second steering controller determine control timings based on alive count values of the first command signal and the second command signal, respectively, wherein the alive count values comprise times at which each of the first command signal and the second command signal are input into the first steering controller or the second steering controller, respectively.
