1. A steering control device comprising:
a first steering control module, which includes a first micro controller unit with a first main memory and a first redundancy memory, configured to delete a stored first code flash from the first main memory and store an update file into the first main memory and the first redundancy memory according to an over-the-air (OTA) update when receiving an OTA update request; and
a second steering control module, which includes a second micro controller unit with a second main memory and a second redundancy memory, configured to receive a control right transitioned from the first steering control module, and store the update file into the second redundancy memory, if the first steering control module receives the OTA update request,
wherein, if the first steering control module completes storing the update file, the second steering control module compares a file stored in the first redundancy memory with a file stored in the second redundancy memory, and
wherein if there is a change in the file stored in the first redundancy memory and the file stored in the second redundancy memory, the second steering control module transitions the control right from the second steering control module to the first steering control module.
