    Abstract: A system for monitoring operation of a vehicle includes a processing device including an interface configured to receive measurement data from sensing devices configured to measure parameters of a vehicle system. The processing device is configured to receive measurement data from each of the plurality of sensing devices, and in response to detection of a malfunction in the vehicle, input at least a subset of the measurement data to a machine learning classifier associated with a vehicle subsystem, the classifier configured to define a class associated with normal operation of the vehicle subsystem. The processing device is also configured to determine whether the subset of the measurement data belongs to the class, and based on at least a selected amount of the subset of the measurement data being outside of the class, output a fault indication, the fault indication identifying the vehicle subsystem as having a contribution to the malfunction.

    Abstract: An internal combustion engine includes a method for operating including, determining, using an accelerator pedal position sensor, an operator request for power and determining an engine operating point based upon the operator request for power. A motored-cylinder temperature is determined based upon the engine operating point, and a knock-limited combustion phasing point is determined based upon the motored-cylinder temperature and the engine operating point. Engine operating parameters associated with achieving the knock-limited combustion phasing point are selected. Operation includes controlling, by a controller, engine control states in response to the engine operating parameters associated with achieving the knock-limited combustion phasing point and the operator request for power.

    Abstract: A disturbance cancellation and generation seat system includes a seat mounted to a structure of a vehicle. The seat is accelerated due to a disturbance acceleration received in the structure and transferred to the seat. A seat control unit generates a force cancellation command signal. An actuation device is connected to the structure and is in communication with the seat control unit. The actuation device in response to receipt of the force cancellation command signal induces a cancellation acceleration motion into the seat which is equal but opposite to and therefore cancels an acceleration motion of the seat induced by the disturbance acceleration.
