Abstract: A LIDAR-to-vehicle alignment system includes a memory and an autonomous driving module. The memory stores points of data provided based on an output of a LIDAR sensor and GPS locations. The autonomous driving module performs an alignment process including performing feature extraction on the points of data to detect one or more features of one or more predetermined types of objects having one or more predetermined characteristics. The features are determined to correspond to one or more targets because the features have the predetermined characteristics. One or more of the GPS locations are of the targets. The alignment process further includes: determining ground-truth positions of the features; correcting the GPS locations based on the ground-truth positions; calculating a LIDAR-to-vehicle transform based on the corrected GPS locations; and based on results of the alignment process, determining whether one or more alignment conditions are satisfied.

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: A vehicle including a fluidic subsystem composed of an electric motor, a motor driver and a fluidic pump that is disposed in a fluidic circuit of the vehicle is described. A controller includes an instruction set that is executable to determine operating parameters associated with the fluidic subsystem, and determine a plurality of power efficiency parameters for the fluidic subsystem based upon the operating parameters. The power efficiency parameters include a hydraulic power efficiency, an electro-mechanical power efficiency and an electric power efficiency. The controller can determine a state of health for the fluidic subsystem based upon the power efficiency parameters, and detect a fault in the fluidic subsystem when the state of health is less than a threshold state of health. The fault can be communicated to a vehicle operator.

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 of processing commands in a vehicle includes receiving a communication from a user. The method further includes determining that the communication is related to health of the vehicle. The method further includes monitoring the vehicle based on the communication. Upon the determination that fault mitigation should be performed, the method further includes arranging maintenance services for the vehicle. The received communication is in a form selected from a voice communication or a gesture-based communication.

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 for mitigating an electrical actuator fault in a system containing multiple actuators includes: applying multiple predetermined conditions to each of multiple actuators in a vehicle system to identify when at least one of the multiple actuators is in a faulted condition; and increasing an input voltage to all of the actuators to increase an output of the at least one of the multiple actuators in the faulted condition to mitigate the faulted condition.

Abstract: A system for on-vehicle camera alignment monitoring includes an on-vehicle camera in communication with a controller. The controller monitors vehicle operating parameters and camera signal parameters, and captures an image file from the on-vehicle camera. A first level analysis of the image file, the vehicle operating parameters, and the camera signal parameters is executed to detect dynamic conditions and image feature parameters that affect camera alignment. An error with one of the dynamic conditions or the image feature parameters that affects the camera alignment is detected. A second level analysis of the camera signal parameters is executed to identify a root cause indicating one of the dynamic conditions or the image feature parameters that affects the camera alignment based upon the error. A camera alignment-related fault is detected based upon the root cause, and vehicle operation is controlled based upon the camera alignment-related fault.
