A system includes a torque overlay device having an input shaft and an output shaft coupled to the input shaft. The system includes a steering wheel coupled to the input shaft. The system includes a processor and a memory storing instructions executable by the processor to detect a torque applied to the input shaft and to actuate the torque overlay device to provide torque to the output shaft in a direction opposite the torque applied to the input shaft.

In a steering device of the present invention, an electric motor rotates a steering shaft through a reduction mechanism, and the reduction mechanism and a torque sensor are accommodated in an integrally-structured housing. With this, the present invention can provide a steering device that is capable of suppressing increase in size of the electric motor.

A vehicle has a lateral lifting device, in particular a side loader, including at least a first cross member and a second cross member, wherein the two cross members are coupled with one another by a connection construction that is disposed laterally outside the center, and wherein the lifting device is disposed in a free space between the two cross members. The first cross member has a first wheel pair, and the second cross member has a second wheel pair, wherein each of the individual wheels of the wheel pairs is mounted so as to rotate about an axis of rotation that is oriented vertically. The vehicle can be moved in a first travel direction parallel to a longitudinal axis of the vehicle, and in a second travel direction transverse to the longitudinal axis of the vehicle.
