In at least one embodiment, an apparatus for adaptively performing diagnostics in a vehicle is provided. The apparatus includes at least one microcontroller and a communication controller. The at least one microcontroller is positioned in a vehicle and is configured to provide first information indicative of operating characteristics for at least one switch in the vehicle. The communication controller is configured to receive the first information from the at least one microcontroller and to wirelessly transmit the first information to a remote server. The communication controller is further configured to receive second information related to a remaining useful life (RUL) for the at least one switch from the remote server and to transmit the second information to the at least one microcontroller to determine when the at least one switch will exhibit a failure.

Health self learning system and method for electrical distribution systems for automated driving vehicles

A method and system to perform the verification of measures done by a sensor in quasi real-time. The sensor verification may be implemented at two different levels&#x2014;a functionality level and a measurement level. At the functionality level, a consistency check of information from different variables may be processed at sensor level depending on the functionality of the physical system being measured. At the measurement level, diagnostics may be performed of the circuits present in the measurement path by specific circuitry and at suitable instants of time to guarantee a Fault Tolerant Time Interval while minimizing sample loss. This may be achieved, at least in part, by increasing the measuring sample rate.

In at least one embodiment, an apparatus for providing age-compensation control for a power converter is provided. The apparatus comprises a controller for being coupled to a power converter including a plurality of phases for converting a first input signal into a first output signal. The controller is configured to activate at least one first switch for a first phase from the plurality of phases for converting the first input signal into the first output signal. The controller is further configured to determine an aging condition for the at least one first switch for the first phase based on an equivalent time, Teq of the at least one first switch, wherein Teq corresponds to an amount of time the at least one first switch is active and on an operating temperature of the at least one first switch while the at least one first switch is active.

A sensor for monitoring battery current includes a shunt and a current source. The shunt has a resistance with an actual value. The current source is configured to provide a known value of current through the shunt. A controller is configured to generate a measured value of the current through the shunt as a function of a measured value of voltage drop across the shunt caused by the current through the shunt and an assumed value of the resistance of the shunt. The controller is further configured to detect the assumed value of the resistance of the shunt as being different than the actual value of the resistance of the shunt when the known and measured values of the current differ.
