1. An electromechanical dual-circuit steering system for a utility vehicle, comprising:
two steering systems, each comprising a drive unit for actuating a respective steering linkage for wheels of the utility vehicle, wherein each drive unit has a respective electric motor;
a main power supply of the dual-circuit steering system for supplying the electric motors with energy; and
at least one emergency power supply for supplying at least one of the electric motors with energy in an event of a failure of the main power supply, wherein
the dual-circuit steering system comprises one substantially independent emergency power supply per electric motor.
