Abstract: A method of detecting a ground fault in a faulty electronic control unit. A ground fault detection technique executed by a processor is enabled. The processor determines a message count for each respective electronic control unit transmitted during a ground offset condition over a predetermined time period. The message count includes messages communicated within a communication bus having a measured voltage at least a predetermined voltage value above an expected voltage value. The message counts for each respective electronic control unit are normalized. The faulty electronic control unit is identified as a function of the normalized message counts. A fault signal is output to identify the fault electronic control unit.

Abstract: A method for monitoring a controller for a vehicle includes determining configuration information associated with the vehicle and determining vehicle operating states associated with a plurality of conditions. A statistical analysis is executed to correlate a plurality of faults with the vehicle operating states and the configuration information associated with the vehicle. The plurality of faults in the controller can be isolated to one of a hardware fault or a software fault based upon the statistical analysis and the configuration information associated with the vehicle.

Abstract: An autonomic vehicle control system includes a perception module of a spatial monitoring system that is disposed to monitor a spatial environment proximal to the autonomous vehicle. A method for evaluating vehicle dynamics operation includes determining a desired trajectory for the autonomous vehicle, wherein the desired trajectory includes desired vehicle positions including an x-position, a y-position and a heading. Vehicle control commands are determined based upon the desired trajectory, and include a commanded steering angle, an acceleration command and a braking command. Actual vehicle states responsive to the vehicle control commands are determined. An estimated trajectory is determined based upon the actual vehicle states, and a trajectory error is determined based upon a difference between the desired trajectory and the estimated trajectory. The trajectory error is monitored over a time horizon, and a first state of health (SOH) is determined based upon the trajectory error over the time horizon.

Abstract: A method for planning and adapting a recommended travel route to a route destination for a vehicle having various subsystems includes identifying the route destination and receiving vehicle health management (VHM)/state of health (SOH) information for each subsystem. The vehicle with a controller programmed to execute the method is also disclosed. The method includes calculating route characteristics of candidate travel routes to the destination using the VHM information and determining, from among the candidate travel routes, travel routes for which the characteristics meet a respective threshold requirement. Thereafter, the controller executes a control action by displaying a candidate route meeting the threshold requirements. An occupant is prompted to revise the mission requirements when no candidate route exists. A default route to a designated parking location or repair depot may be displayed when none of the candidate routes meet the threshold requirements.

Abstract: A method for diagnosing a fault mode in a system includes recording a hierarchical precedence rule assigning a priority level to fault modes of the system, and recording, in a fault report matrix, fault reports indicative of a corresponding one or more of the fault modes. The method also includes using the hierarchical precedence rule to determine the assigned relative priority level for the fault reports in response to a predetermined condition, e.g., a requested engine starting event, and identifying a root cause subsystem as a subsystem having the highest assigned priority level. A control action executed via the controller identifies the root cause subsystem by recording a diagnostic code and/or transmitting a message. The system is also disclosed, as is a computer-readable medium programmed with instructions embodying the method.
