Abstract
A virtual high voltage interlock is disclosed that utilizes a software-based function (e.g., an electronic control unit) to determine if there are any open wires or connectors, based on voltage signals reported by internal components, to prevent high voltage exposure. The electronic control unit instructs a power source to charge a DC bus to a safety voltage, receives measured voltage readings, via a control area network, from at least one high voltage component coupled to the DC bus, and provides an operating voltage to the DC bus in response to the measured voltage readings being acceptable.
