    摘要: A method for allocating forces among the corners of a vehicle having a redundant actuator suite includes determining a set of desired forces at the center of gravity of the vehicle, and allocating the set of desired forces among the corners of the vehicle as virtual control commands using a controller. The method also includes mapping the virtual control commands at the corners to actual or true control commands at the corners, and controlling a plurality of actuators at the corners using the actual or true control commands. The actuators may include friction brakes and wheel motors. Mapping the virtual control commands may include using a Least Squares formulation. Control of the actuators may be prioritized with respect to each other using weighting matrices. A vehicle includes a controller having actuators and a controller configured for executing the above method.
