    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： A method and system to monitor a high voltage power relay operable to conduct electrical power from a source to a load, during each vehicle shutdown event. The system includes the electrical relay with a resistive device, electrically connected in parallel circuit, a controllable electrical load device, and a sensing device. A controller is connected to the electrical relay and each sensing device, and operable to identify a low electrical load condition at the load. The controller commands the load to operate at a known current draw level, commands the relay open, and monitors a change in power to the load device when the relay is commanded open. The electrical relay is functioning properly when the change in electrical power to the load exhibits a known profile over time, when the electrical relay is controlled to the commanded-open position.
