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 vehicle includes an electrically-driven motor configured to actuate a vehicle component and a power source configured to provide power to the motor over an electrical circuit. The vehicle also includes a controller programmed to monitor at least one signal indicative of motor output and store data indicative of a resistance in the circuit. The controller is also programmed to issue a resistance state of health signal in response to the resistance in the circuit exceeding a predetermined resistance threshold.

Abstract: Methods and system are provided for monitoring a controller area network (CAN) bus. In one embodiment, a method includes: receiving fault data associated with the CAN bus; processing, by a processor, the fault data with a software based method to determine a first propositions set; processing, by the processor, the fault data with a hardware based method to determine a second proposition set; processing, by the processor, the first propositions set and the second proposition set to determine a fault decision; and generating, by the processor, a diagnosis of the CAN bus based on the fault decision.

Abstract: A vehicle including a monitoring system and controller for evaluating a vehicle subsystem is described. The monitoring system includes a sensor that is disposed to monitor on-vehicle noise or vibration. The subsystem includes an actuator, and a fault associated with the subsystem is defined by a fault vibration signature. A command to activate the subsystem is monitored coincident with a signal input from the sensor. A first vibration signature is determined based upon the signal input from the sensor, and a correlation between the first vibration signature and the fault vibration signature are determined for the fault associated with the subsystem. Occurrence of a fault associated with the subsystem can be detected when the correlation between the first vibration signature and the fault vibration signature associated with the subsystem is greater than a threshold correlation.

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.

Abstract: A method is disclosed for detecting ground faults in a communications system. The method includes measuring a predetermined number of voltage points; determining if the measured voltage points represent recessive or dominant bits; identifying which of the predetermined number of voltage points represent inter-frame bits and which represent frame data bits based on whether the measured voltage points are recessive or dominant; calculating a maximum average voltage for the inter-frame bits; calculating an average frame voltage for all dominant bits within a frame; determining a high average dominant voltage count based on a number of frames for which the average frame voltage is greater than a high voltage threshold; and determining if a ground fault exists based on the average frame voltage and the high average dominant voltage count.

Abstract: A system for designing a driving system for a vehicle. The system includes a first sensor, a second sensor and a processor. The first sensor is configured to obtain an external parameter indicative of a lane marking during a time period in which an automated driving program is being operated at the vehicle. The second sensor is configured to obtain an internal parameter of the vehicle during the time period. The processor is configured to detect a lane touch event occurring during the time period, determine an error occurring in the driving system resulting in the lane touch event based on the internal parameter and the external parameter, identify a failure domain of the driving system in which the error occurs, and change a design of a program of the driving system related to the failure domain.

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.
