Abstract

A method and system are provided to eliminate the risk of over temperature concerns associated with electrical heating devices, which if undetected may result in an electrical over temperature condition. The electrical heating system may be applied to the detection and control structure of other automotive electrical loads where thermal concerns may exist. The electrical heating system combines several layers of fault detection strategies, to form a unique comprehensive approach to prevent and detect potential electrical fault conditions, which if undetected and/or controlled may result in an electrical over temperature condition.

Description

[0001] Cross References to Related Applications [0002] This patent application claims priority to US Provisional Patent Application Serial No. 61 / 408,446, filed October 29, 2010, which is hereby incorporated by reference in its entirety. technical field [0003] Exemplary embodiments relate to electrical heating systems, and more particularly, to fault detection and handling in heating systems. Background technique [0004] Heating systems are used in vehicles to provide driver and passenger comfort, as well as for functional aspects of the vehicle. Although heating systems generally perform as designed, heating systems run the risk of operating outside of specification for a number of reasons. Contents of the invention [0005] According to exemplary embodiments, a heating system for a vehicle and a method for the heating system are provided. The heating control module includes a microprocessor configured for heating fault detection and heating fault handling, a first...
