Abstract:
A distributed active suspension control system is provided. The control system is based on a distributed, processor-based controller that is coupled to an electronic suspension actuator. The controller processes sensor data at the distributed node, making processing decisions for the wheel actuator it is associated with. Concurrently, multiple distributed controllers on a common network communicate such that vehicle-level control (such as roll mitigation) may be achieved. Local processing at the distributed controller has the advantage of reducing latency and response time to localized sensing and events, while also reducing the processing load and cost requirements of a central node. The topology of the distributed active suspension controller contained herein has been designed to respond to fault modes with fault-safe mechanisms that prevent node-level failure from propagating to system-level fault. Systems, algorithms, and methods for accomplishing this distributed and fault-safe processing are disclosed.
