Abstract

A vehicle has at least two drive wheels which can be driven in each case by single-wheel drive units which are in particular of structurally identical dimensions and which can be actuated by means of a control device, control device determines a target torque which, in a torque distribution unit, can be divided into a first target torque for the first drive unit and a second target torque for the second drive unit. The torque distribution unit is assigned an adjustment unit by means of which the first and/or the second target torque can be corrected with an adjustment factor which can be determined as a function of a torque difference, arising owing to manufacturing and/or component tolerances, between the drive units.
