Abstract: An autonomic vehicle control system includes a vehicle spatial monitoring system including a plurality of spatial sensors disposed to monitor a spatial environment proximal to the autonomous vehicle. A controller is in communication with the spatial sensors of the vehicle spatial monitoring system, and the controller includes a processor and a memory device including an instruction set. Evaluating operation of the autonomous vehicle includes commanding operation of an actuator that is disposed to effect operation of the autonomous vehicle and simultaneously monitoring dynamic operation of the autonomous vehicle via a plurality of the spatial sensors. The commanded operation of the actuator is correlated with the dynamic operation of the autonomous vehicle, and a fault can be detected in the actuator based upon the correlation.

Abstract: A method for use with a vehicle having one or more subsystems includes receiving vehicle health management (VHM) information via a controller indicative of a state of health of the subsystem. The VHM information is based on prior testing results of the subsystem. The method includes determining a required testing profile using the testing results, applying the testing profile to the subsystem to thereby control a state of the subsystem, and measuring a response of the subsystem to the applied testing profile. The method also includes recording additional testing results in memory of the controller that is indicative of a response of the subsystem to the applied testing profile. The vehicle includes a plurality of subsystems and a controller configured to execute the method.

Abstract: A method proactively transitions performance of a functional operation from a primary subsystem to a secondary subsystem within a vehicle or other system having an electronic control unit (ECU). The method includes receiving health management information via the ECU when the primary subsystem is actively performing the functional operation within the system and the secondary subsystem operates in a standby mode, wherein the health information is indicative of a numeric state of health (SOH) of the primary subsystem. The method also includes comparing the numeric SOH to a calibrated non-zero threshold SOH, and then commanding, via the ECU, a transition of the performance of the functional operation to the secondary subsystem and placing the primary subsystem in the standby mode when the numeric SOH is less than the calibrated non-zero threshold SOH. A vehicle executes the method via the ECU.

Abstract: An autonomic vehicle control system is described, and includes a vehicle spatial monitoring system including a subject spatial sensor that is disposed to monitor a spatial environment proximal to the autonomous vehicle. A controller is in communication with the subject spatial sensor, and the controller includes a processor and a memory device including an instruction set. The instruction set is executable to evaluate the subject spatial sensor, which includes determining first, second, third, fourth and fifth SOH (state of health) parameters associated with the subject spatial sensor, and determining an integrated SOH parameter for the subject spatial sensor based thereupon.

Abstract: An autonomic vehicle control system includes a vehicle spatial monitoring system including a plurality of spatial sensors disposed to monitor a spatial environment proximal to the autonomous vehicle. A controller is in communication with the spatial sensors of the vehicle spatial monitoring system, and the controller includes a processor and a memory device including an instruction set. The instruction set is executable to generate a perception result associated with a static field of view for each of the spatial sensors, wherein each of the spatial sensors is positioned at an analogous orientation to generate the respective perception result associated with the static field of view. The perception results from the plurality of spatial sensors are compared to detect a fault associated with one of the spatial sensors.

Abstract: A method of isolating a fault in an electric power steering system includes calculating a value for fault signature components. Each of the calculated values of the fault signature components is compared to a respective threshold value, to determine if any of the calculated values of the fault signature components exceeds its respective threshold value. When at least one of the calculated values of the plurality of fault signature components exceeds its respective threshold value, the above threshold comparison results are compared to a fault table that relates pre-calculated threshold comparison results to pre-identified faults, to determine if the above threshold comparison results correspond to a pre-identified fault. Based on the fault table comparison results, a control action is automatically executed to indicate a pre-identified fault or an unknown fault in the electric power steering system.
