    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 comparing module receives first data regarding surroundings of a vehicle from a plurality of sensors in the vehicle, receives second data regarding the surroundings from the plurality of sensors after receiving the first data, compares the first data to the second data, and determines a first difference between the first data and the second data based on the comparison of the first data to the second data. A perception module generates a first set of perception results based on the first data, generates a second set of perception results based on the second data, and determines a second difference between the first data and the second data based on the first set of perception results and the second set of perception results. A diagnostics module determines whether one of the sensors or the perception module is faulty based on a combination of the first difference and the second difference.

    Abstract: Systems and method are provided for controlling a vehicle. In one embodiment, a method includes: recording, by a controller onboard the vehicle, lidar data from the lidar device while the vehicle is travelling on a straight road; determining, by the controller, that the vehicle is travelling straight on the straight road; detecting, by the controller, straight lane marks on the straight road; computing, by the controller, lidar boresight parameters based on the straight lane marks; calibrating, by the controller, the lidar device based on the lidar boresight parameters; and controlling, by the controller, the vehicle based on data from the calibrated lidar device.

    Abstract: System and method for controlling operation of a vehicle in real-time with a supervisory control module. A fault detection module is configured to receive respective sensor data from one or more sensors in communication with the vehicle and generate fault data. The supervisory control module includes at least one fault-tolerant controller configured to respond to a plurality of faults. The supervisory control module is configured to receive the fault data. When at least one fault is detected from the plurality of faults, the supervisory control module is configured to employ the fault-tolerant controller to generate at least one selected command. The selected command is transmitted to one or more device controllers for delivery to at least one of the respective components of the vehicle. Operation of the vehicle is controlled based in part on the selected command.

    Abstract: A method of on-line diagnostic and prognostic assessment of an autonomous vehicle perception system includes detecting, via a sensor, a physical parameter of an object external to the vehicle. The method also includes communicating data representing the physical parameter via the sensor to an electronic controller. The method additionally includes comparing the data from the sensor to data representing the physical parameter generated by a geo-source model. The method also includes comparing results generated by a perception software during analysis of the data from the sensor to labels representing the physical parameter from the geo-source model. Furthermore, the method includes generating a prognostic assessment of a ground truth for the physical parameter of the object using the comparisons of the sensor data to the geo-source model data and of the software results to the geo-source model labels. A system for on-line assessment of the vehicle perception system is also disclosed.

    Abstract: A method is used to evaluate a camera-related subsystem in a digital network, e.g., aboard a vehicle or fleet, by receiving, via a camera diagnostic module (CDM), sensor reports from the subsystem and possibly from a door sensor, rain/weather sensor, or other sensor. The CDM includes data tables corresponding to subsystem-specific fault modes. The method includes evaluating performance of the camera-related subsystem by comparing potential fault indicators in the received sensor reports to one of the data tables, and determining a pattern of fault indicators in the reports. The pattern is indicative of a health characteristic of the camera-related subsystem. A control action is executed with respect to the digital network in response to the health characteristic, including recording a diagnostic or prognostic code indicative of the health characteristic. The digital network and vehicle are also disclosed.
