Claim 11:
12. A vehicle comprising:
a steering system having:
at least one electrical three-phase machine;
at least one control circuit configured to actuate the at least one electrical three-phase machine;
at least one compensation device operatively connected to the at least one control circuit and configured to reduce a torque ripple of the at least one electrical three-phase machine based on a compensation signal; and
a computing unit configured to determine at least one compensation parameter of the at least one compensation device based on a correlation of at least one first operating parameter with (i) a pre-commutation angle of the at least one electrical three-phase machine and (ii) a supply voltage of the at least one electrical three-phase machine,

wherein the at least one compensation parameter is used to generate the compensation signal, and
wherein the pre-commutation angle is an angle between a current vector and a q-axis of a coordinate system based on a rotor field of the at least one electrical three-phase machine.
