A vehicle and a steering system of a vehicle. The steering system includes a steering column emulator that generates an electrical driving signal in response to a driver input, a steering rack assembly that receives the electrical driving signal from the steering column emulator and controls steering of the vehicle as indicated by the received signal, and a backup system. The backup system provides a backup electrical driving signal to the steering rack assembly upon a failure of the steering column emulator, and the steering rack assembly steers the vehicle as indicated by the backup electrical driving signal upon the failure of the steering column emulator.
