Abstract:
1. A method of logging faults in an electronic controlled internal combustion engine having an electronic control unit with memory, said electronic control unit comprising a motor control module in electronic communication with at least one sensor to provide data signals including vehicle operating conditions; said motor control module in electronic communication with a Common Powertrain Controller; said Common Powertrain Controller further equipped with a fault manager for logging said faults, said method comprising: sensing engine operating conditions and transmitting a data signal indicative of said engine operating conditions to said electronic control unit; filtering said data signals from said sensor through a debounce logic; said logic comprising a timer to measure time duration of an error in said data signal; a recovery time for any deactivation of an error and a healing time for an inactive fault self deletion; logging any faults after debounce filtering in memory in a fault table in a fault control module; commanding said faults from said fault control memory up to 10 times per second to said Common Powertrain Controller and once per second to said motor control module; and activating any alerts indicating said fault.
