A method (300) of control allocation in a multi-unit vehicle combination is provided, wherein the units (110a, 110b) include actuators configured to generate propulsion and/ or braking forces. The method includes receiving a virtual control input (v) for the vehicle combination as a whole, solving (320) a control allocation problem to find a true control input (u) for the actuators, including attempting to minimize a difference between the true control input and a reference control input (u ref ). The method includes controlling the actuators based on the true control input. In particular, the method includes generating (330) the reference control input such that a) capabilities ( u and ū) of the actuators are taken into account, and b) such that a longitudinal force contribution of one vehicle unit does not counteract the contribution of another vehicle unit. A controller, vehicle unit, vehicle unit combination, computer program and computer program product are also provided.
