A utility vehicle steering system has a steering gear for transmitting a manual torque that is applied to a steering wheel to a pitman arm. The steering gear has an electric motor for providing an auxiliary torque. The electric motor is arranged around a steering shaft. In addition, the electric motor has a stator with at least two electrically separated winding groups, each of which is controlled by a separate electronic control device. An especially compact utility vehicle steering system results, which enables the provision of large auxiliary torques by way of a single electric-motor drive while a limited installation space is achieved. The drive can be operated from a vehicle electrical system by a supply voltage of 24 V.
