摘要： An EGR valve position control system includes an EGR valve manager responsive to an EGR valve command to drive an EGR valve actuator. The EGR valve manager is operable to schedule control gains as a function of valve actuation direction to provide for faster response during valve closing events. Valve closing events are also staged such that a large valve position step is followed by a steady ramp to the valve closed position to thereby prevent damage to the valve and/or valve seat. The EGR valve manager further includes a prioritized switching feature for strategically switching between closed and open loop control modes, and a forward gain adjustment feature responsive to battery voltage to maintain constant system DC gain under changing battery voltage conditions.

摘要： An EGR fault/failure determination system for an internal combustion engine is operable to monitor a number of EGR system operational parameters and diagnose various EGR-related fault and failure statuses therefrom. For example, the system is operable to determine a number of EGR system-related fault and failure conditions by monitoring measured and command EGR position signals to determine EGR valve controller functionality, to monitor response times between fully open and closed EGR valve positions by comparing measured response times to a calibratable response time value, and to monitor in-range EGR position failures associated with fully closed and fully opened EGR valve position values. The system further includes a Kalman filter-based fault/failure isolation feature operable to isolate and identify one or more sources of EGR valve-related faults/failures.

摘要： A clock down sensor mainly comprises a converter and a low-pass filter. The converter is used to convert an input signal from a PECL (Positive Emitter Coupling Logic) signal to a TTL (Transistor Transistor Logic) signal, the low pass filter is used to obtain a DC (Direct Current) level of the TTL signal. Thereby, the sensor can judge whether the clock signal is terminated according to the potential of the output signal in order to emit a warning so that a breakdown elimination inquiry can be done or automatic breakdown elimination can be processed earlier.
