A vehicle control unit arranged to control motion of a heavy-duty vehicle comprising first and second electric machine (EM) arrangements, wherein the vehicle control unit is arranged to control the first and second EM arrangement by transmitting wheel slip requests to respective EM control units, wherein the control unit is arranged to obtain a desired total longitudinal force to be jointly generated by the first and second EM arrangements, wherein the control unit is arranged to determine a desired first wheel slip corresponding to a first longitudinal force generated by the first EM arrangement, and a desired second wheel slip corresponding to a second longitudinal force generated by the second EM arrangement, wherein the control unit is arranged to balance a magnitude of the first wheel slip relative to a magnitude of the second wheel slip in dependence of the efficiency characteristics of the first and second EM arrangements.
