Method and Apparatus for Controlling a Vehicle

A method of controlling a vehicle is disclosed, the method comprising steps of: determining a saturated reference yaw moment based on an initial reference yaw moment and a total wheel torque demand, taking into account operational limits of the vehicle; determining initial torque allocations for each one of a plurality of wheels of the electric vehicle based on the saturated reference yaw moment; and for each one of the plurality of wheels, checking whether the initial torque allocation for said wheel exceeds a corresponding wheel torque limit for said wheel. In response to a determination that the initial torque allocation for a first wheel exceeds the corresponding wheel torque limit, and that the initial torque allocation for a second wheel on the same side of the vehicle is less than the corresponding wheel torque limit, the initial torque allocations are revised by increasing the torque allocation to the second wheel. The electric vehicle can then be controlled to apply the revised torque allocations to the plurality of wheels. Apparatus for controlling a vehicle is also disclosed.
