OPTIMIZED FORCE ALLOCATION: A General Approach to Control and to Investigate the Motion of Over-Actuated Vehicles

A general approach is introduced to allocate the forces acting on the center of gravity to the four wheels of a vehicle by using an inversion of vehicle dynamics and a non-linear optimization. This makes it possible to compare all useful configurations of actively and passively controlled influencing variables of vehicle dynamics (steering angles, brake/drive torques, wheel loads and camber angles), with and without actuator dynamics and to investigate the impact of actuator failures on vehicle dynamics.
