摘要：An electric motor system having substantially independent hardware-based andsoftware-based pathways for detecting and initiating responses to fault conditions, suchas over-current conditions, in an electric motor which is powered by a power inverter
which is controlled by a power module and a microprocessor. Each pathway involvescomparing a voltage, which is representative of an electric current flowing to the motor,to a predetermined maximum voltage, and if the former exceeds the latter using
hardware or software to initiate shutting off the motor, such as by shutting off the powerinverter. When one pathway detects a fault condition it may notify the other pathway, andthe notified pathway may also initiate shutting off the motor.
