1. Vehicle dynamics control system architecture comprising:
- at least one vehicle sub-system normally controlled in accordance with sub-system controls determined by at least one respective sub-system controller; and
a vehicle dynamics controller for providing high priority sub-system commands for implementation by said at least one respective sub-system controller, said vehicle dynamics controller including multi-layer software components and inter-layer busses wherein selected ones of said multi-layer software components can be decomposed and recomposed independently from other ones of said multi-layer software components and said inter-layer busses provide access to respective inputs and outputs of said multi-layer software components.
