Abstract

This work proposes to approach Global Chassis Control (GCC) by means of model inversion based feedforward with allocation directly on the actuator commands. The available degrees of freedom are used to execute the desired vehicle motion while minimizing the utilization of the tyre's grip potential. This is done by sampled constrained least-squares optimization of the linearized problem. For compensation of model errors and external disturbances, high gain feedback is applied by means of an Inverse Disturbance Observer. The presented method is applied on a comparison of eight vehicles with different conguration of actuators for steer, drive, brake and load distribution. The approach shows a transparent and effective way to deal with the complex issue of GCC in a unitized way. It gives both a base for controller design and a structured way to compare different configurations. In practice, the transparency supports automatic on-board reconfiguration in case of actuator hardware failure.
