Loss of input signal detection and response system for use with distributorless ignition systems |
摘要 |
An invention for detecting loss of input signals to a distributorless ignition system (17) and for providing appropriate responses upon detecting fault conditions. If a SPOUT signal (31) faults low, the invention will control ignition sequence through use of a CID signal (14), and the CID signal (14) and a PIP signal (13) will be operably substituted for the missing SPOUT signal (31) to assure timely ignition. If the SPOUT signal (31) faults high, the CID signal (14) will again be utilized to sequence the firing sequence and the PIP signal (13) will be substituted for the SPOUT signal (31). If the CID signal (14) faults, firing sequence will continue to be incremented in response to receipt of the SPOUT signal (31). In addition, the invention provides for recovery of normal operation should any of the above fault conditions prove to be transient.
