Abstract
A method of managing over-temperature excursions in an electronic control unit of a control system having failed-fixed capability and an operationally independent temperature monitoring and power enable function. The method includes receiving a temperature signal indicative of a temperature associated with an electronic control unit, determining if the temperature associated with the electronic control unit exceeds a first selected threshold, determining if the temperature associated with the electronic control unit exceeds a second selected threshold, and ascertaining if an engine associated with the control system is operational. The method also includes that if the engine is not operational and the temperature exceeds the first selected threshold, then disabling an actuator associated with the control system. In addition, the method also includes that if the temperature associated with the electronic control unit exceeds the second selected threshold, then disabling an actuator associated with the control system.
