Abstract
A steer-by-wire steering system for motor vehicles may include a primary steering level with a steering transmission device, which is arranged to subject wheels of the motor vehicle to a desired setpoint steering effect, and a secondary steering level with a safety device that provides predefined functions, so that in the case of a malfunction of the primary steering level, steering the wheels remains possible during an emergency mode. The steer-by-wire steering system may also include an authentication system with a communications interface for communications with the safety device. The authentication system may be arranged so that in the case of a successful authorization, the secondary steering level of the steer-by-wire steering system is also available after the emergency mode.
