Abstract: The exhaust from a diesel-fueled internal combustion engine is treated by a lean NOX trap. The maximum temperature used for desulfating the lean NOX trap is kept relatively lower during early life and progressively increased as the trap ages. Designing for adequate late life performance entails excess capacity during early life. The method utilizes the excess capacity available during early life to slow aging of the trap and thereby extend the trap lifetime. The method facilitates meeting durability requirements for diesel-powered vehicles with exhaust aftertreatment.

Abstract: A method and system for a misfire detection acquires (301) a series of acceleration data (302) representative of acceleration behavior of an engine. The data is sampled (304) to obtain acceleration data samples at a rate sufficient to obtain up to fourth-order perturbations of the data. The samples are filtered (322) to provide bandwidth limited samples, which are provided to at least two channels (325, 329). The samples are pattern matched (332) in a first channel to enhance harmonic phenomena and pattern canceled (330) in a second channel to enhance random phenomena. Hard and random misfires are detected (334) dependent on a magnitude of the filtered acceleration data samples. Preferably, a third channel (335) is added to detect multiple misfires.

Abstract: An electronic throttle controller (200) includes a feedforward control (222), a PID (224), a sliding mode control (226) and an adder (230). The PID (224) is capable of generating a first feedback term that compensates for an error signal. The sliding mode control (226) is capable of generating a second feedback term that incorporates a solution to a Lyapunov equation applied to the error signal with sliding gain being updated by an estimation of unknown dynamics. The adder (230) adds the first feedback term, the second feedback term and the feedforward control (222) so as to generate a control signal (232).

Abstract: An occupant classification system for a seat assembly. The seat assembly includes a seat cushion and a seat back. The system comprises a plurality of sensors, an algorithm, a posture classifier and a weight classification system. Each of the plurality of sensors measures a force applied to the seat cushion and/or seat back by an occupant of the seat assembly. The algorithm monitors a compensation factor and adjusts the forces measured by the plurality of sensors to compensate for the compensation factor. The posture classifier identifies a posture of the occupant based on distribution of the adjusted forces for each of the plurality of sensors. The weight classification system identifies a weight class of the occupant based on the posture and magnitude of the adjusted forces for each of the plurality of sensors.

Abstract: A vehicle has an exhaust aftertreatment system including an LNT. The vehicle operates through a series of ignition cycles, deNOX cycles, and deSOX cycles. DeNOX operations begin when the LNT reaches a loading threshold. The applicable threshold depends on operating conditions, such as mean LNT temperature and mean exhaust flow rate. The thresholds are adapted based on NOX removal efficiency data. The data is compared to target values. The target values depend on the operating condition range, but remain fixed while the thresholds are adapted. NOX removal efficiency is measured over intervals corresponding to entire deNOX cycles. The data is sorted into bins according to operating conditions. The adaptations are only made if a bin has several data points accumulated over a minimum interval that is at least one ignition or deSOX cycle, preferably several. The method provides stable adaptations that compensate for aging.
