    摘要： A method to monitor integrity of a signal output from an operator-manipulable transmission range selector for a powertrain system includes equipping the transmission range selector with a range encoder and a direction encoder, determining a range state and a direction state based upon signals from the range encoder and the direction encoder, determining a discrete position of the transmission range selector based upon the range state and the direction state, and performing back rationality to verify the discrete position of the transmission range selector.

    摘要： A method includes detecting a first event and executing a first procedure to identify a sensor offset in response to detecting the first event. The method further includes determining, via a computing device, whether the sensor offset was measured during the execution of the first procedure, scheduling a second procedure to execute in response to detecting a second event if the sensor offset was not measured during the first procedure, and scheduling the first procedure to execute in response to detecting a subsequent occurrence of the first event if the sensor offset was measured during the first procedure.

    摘要： An inhibit path diagnostic system includes a first control module. The first control module includes a message output and transmits a first message from the message output to a controller area network (CAN) via a message transmission path. An inhibit path circuit includes the message transmission path. A second control module transmits a disable control signal to the inhibit path circuit to disable the message transmission path. The first control module transmits a second message from the message output subsequent to and based on the transmitting of the disable control signal. At least one of the first control module and the second control module detects a fault of the inhibit path circuit subsequent to the transmitting of the second message and based on a feedback signal from the CAN.

    摘要： Methods and systems are provided for monitoring an automotive electrical system including an inverter having at least one switch. First and second voltage commands corresponding to respective first and second components of a commanded voltage vector on a synchronous frame of reference coordinate system are received. A plurality of duty cycles for operating the at least one switch are calculated based on the first and second voltage commands. First and second actual voltages are calculated based on the plurality of duty cycles. The first and second actual voltages correspond to respective first and second components of an actual voltage vector on the synchronous frame of reference coordinate system. An indication of a fault is generated based on the difference between the first components of the commanded voltage vector and the actual voltage vector and the difference between the second components of the commanded voltage vector and the actual voltage vector.
