摘要： A method and system of misfire determination includes establishing an acceleration misfire threshold and an acceleration sub-misfire threshold. Then incremental engine position is sensed and a series of acceleration data-points are derived (401). If a data-point of the series of acceleration data-points falls between the sub-misfire threshold and the misfire threshold, then a training process is aborted for a blanking period based on a delay time whose length is preferably based on engine operating conditions (415). If a data-point of the series of acceleration data-points does not fall below the sub-misfire threshold, then the series of acceleration data-points, are averaged and a synchronously corrected acceleration data-point is derived (417). Then, a misfire condition is indicated when the synchronously corrected acceleration data-point exceeds the established acceleration misfire threshold (421).

摘要： A method for monitoring the performance of a catalytic converter (34) computes the oxygen storage capacity and desorption capacity of a catalyst within the catalytic converter (34). An engine control unit (10) receives mass flow rate information of air from a mass air flow rate sensor (12) and an injector driver (24), and receives electrical signals from an upstream exhaust gas sensor (28) and a downstream exhaust gas sensor (30). A rate modifier is determined from excess air ratios and an adaptation parameter. The engine control unit (10) calculates normalized air fuel ratios for the exhaust gas entering and leaving the catalytic converter (34) and performs numerical integration using the rate modifier to determine the oxygen storage capacity of the catalyst in the catalytic converter (34). The calculated oxygen storage capacity of the catalyst can be compared with threshold values to determine the performance of the catalytic converter (34).

摘要： A system and method of detecting a leak in an evaporative emissions system for a vehicle includes measuring a physical disturbance of the vehicle with a sensory system and providing a sensory signal (311, 313, 315). Then, comparing the sensory signal (311, 313, 315) to a threshold (405) and generating a diagnosis signal (407, 413) having a "valid test" state, when the sensory signal does not exceed the threshold, and generating the diagnosis signal having an "invalid test" state, when the sensory signal exceeds the threshold. And, executing an evaporative emissions system leak test while the provided diagnosis signal indicates the "valid test" state, and aborting the evaporative emissions system leak test (505) when the diagnosis signal indicates the "invalid test" state.

摘要： A remotely controlled electronically actuated vehicle differential system is disclosed. In one embodiment, an electronically actuated vehicle differential is selectively controlled via a remote control unit. The remote control unit generates differential activation and deactivation signals that are received by a wireless receiver unit disposed within a vehicle. An electronically actuated differential is operatively coupled to receive input signals from the wireless receiver unit. The operational status (i.e., engagement or disengagement of a traction modifying differential gear mechanism) of the electronically actuated differential is controlled by the input signals received from the wireless receiver. In one embodiment, the electronically actuated differential comprises an electronically actuated locking differential. In this embodiment, the electronically actuated locking differential fully locks the differential when the locking differential activation signals are received by the wireless receiver unit. The electronically actuated locking differential unlocks the differential when the locking differential deactivation signals are received by the wireless receiver unit.
