Abstract: A method for detecting early life failure of an electrical connection of a power harness for a steering system of a vehicle including, using a processor configured to execute instructions, obtaining a resistance measurement associated with an electrical power delivery system including the electrical connection, obtaining historical resistance data obtaining at least one limit based on at least one of the historical resistance data and a functional limit, detecting an early life failure of the electrical connection based on a comparison between the resistance measurement and the at least one limit, performing at least one action in response to detecting the early life failure.

Abstract: An electrical terminal assembly for a vehicle electrical connector assembly includes a header. The electrical terminal assembly also includes a potting material disposed within a cavity of the header. The electrical terminal assembly further includes an electrical terminal extending through the header and the potting material, the electrical terminal formed of metal and having a non-uniform outer surface including at least one engagement feature for adhering to the header and the potting material.

Abstract: A method for detecting degradation intermittencies in an electrical connection in a steering system of a vehicle includes, using a processor configured to execute instructions, receiving an input indicative of a plurality of measurements of resistance associated with the electrical connection, calculating, based on the received input, at least one adaptive control threshold, comparing a first measurement of the plurality of measurements to the at least one adaptive control threshold, determining whether the electrical connection has a degradation intermittency in response to the comparison between the first measurement and the at least one adaptive control threshold, and performing at least one action in response to determining that the electrical connection has the degradation intermittency.

Abstract: Technical solutions are described for diagnosing an input power supply providing power to a motor. A method includes: generating a sinusoidal stimulus signal; applying, using the input power supply, the sinusoidal stimulus signal to the motor; measuring a response to the sinusoidal stimulus signal; determining a degraded condition of the input power supply based on the response to the sinusoidal stimulus signal; and performing an action in response to determining the degraded condition of the input power supply.

Abstract: A method for diagnosing an input power supply providing power to a motor includes: applying, using the input power supply, a power stimulus to the motor; measuring a response to the power stimulus; calculating, based on the response to the power stimulus, a metric indicative of a status of the input power supply; determining a degraded condition of the input power supply based on the metric indicative of the status of the input power supply; and performing an action in response to determining a degraded condition of the input power supply. The action may include one or more of: limiting an output power supplied to the motor; generating a diagnostic trouble code; and/or notifying an operator of the degraded condition of the input power supply.

Abstract: A method for determining a state of health (SOH) of an electrical connection in a steering system includes, using a processor configured to execute instructions, receiving an input indicative of the SOH of the electrical connection, the input including a resistance associated with the electrical connection, and the SOH corresponding to at least one of an accumulated health (AH) of the electrical connection and a remaining usable life (RUL) of the electrical connection, calculating, based on the received input and usage associated with the vehicle, a first SOH value, calculating, based on the received input and behavior associated with the vehicle, a second SOH value, calculating, based on the first SOH value and the second SOH value, a third SOH value, the third SOH value being an indicator of the AH or the RUL of the electrical connection, and performing at least one action based on the third SOH value.
