摘要： A method of identifying a fault in a friction brake actuated by hydraulic brake pressure and configured to decelerate a vehicle road wheel includes detecting, via a first sensor, a vibration at the road wheel and communicating data indicative of the detected vibration to a controller. The method additionally includes detecting, via a second sensor, upon application of the hydraulic brake pressure, a hydraulic brake pressure variation and communicating data indicative of the detected hydraulic brake pressure variation. The method additionally includes comparing, via the controller, the data indicative of the detected vibration with a threshold vibration value and the data indicative of the detected hydraulic brake pressure variation with a threshold hydraulic brake pressure value. Furthermore, the method includes generating a sensory signal indicative of the brake fault when magnitudes of the detected vibration and the detected hydraulic brake pressure variation are greater than their respective threshold values.

摘要： 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.

摘要： 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.

摘要： A method of operating an electric power steering system installed on a vehicle. The electric power steering system includes a controller that receives a desired assist torque value and supplies a pulse-width modulation duty cycle to an electric motor. The method includes the step of controlling the electric motor to achieve a nominal value of power steering assist torque when the electrical power available to the motor is sufficient to achieve the nominal value of power steering assist torque. The method further includes the step of controlling the electric motor to achieve a reduced value of power steering assist torque less than the nominal value when the electrical power available to the motor is not sufficient to achieve the nominal value of power steering assist torque.

摘要： A system for a vehicle includes a plurality of sensors onboard the vehicle and a controller. A first sensor of the plurality of sensors is configured to detect lane markings on a roadway. The controller is configured to store data from the plurality of sensors. In response to receiving an indication indicating a misdetection of lane markings on the roadway based on data received from the first sensor, the controller is configured to execute in parallel a plurality of procedures configured to detect a plurality of causes for the misdetection of lane markings, respectively, based on the stored data; isolate one of the causes as a root cause for the misdetection of lane markings; and provide a response for mitigating the misdetection of lane markings on the roadway based on the root cause for the misdetection of lane markings.

摘要： 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.

摘要： A method of controlling a vehicle having an electric power steering system includes generating a plurality of possible routes. Each of the plurality of possible routes that require a steering torque that is within an available torque range is identified as a system compliant route. Each of the plurality of possible routes that require an angular position of an electric motor of the electric power steering system at all time indices throughout that route that are within an available motor position range are also identified as a system compliant route. One of the identified system compliant routes is selected based on at least one selection criteria, and designated as an active route. The electric power steering system is then controlled to maneuver the vehicle along the active route. The electric power steering system is monitored as the vehicle moves along the active route to identify degradation of its capabilities.
