Patent number: 8364376Abstract: A control system for an engine having a catalytic converter includes an energy calculation module that calculates a calculated mass air flow (MAF) of intake air of the engine based on a requested torque and a requested spark timing that correspond to a desired thermal energy of exhaust of the engine, and that determines an expected thermal energy of the exhaust based on the calculated MAF, and an energy residual module that determines a thermal energy residual of the exhaust based on the expected thermal energy and an estimated thermal energy of the exhaust, wherein the estimated thermal energy is based on a measured MAF of the intake air. The control system includes an energy evaluation module that determines a diagnostic result that indicates whether the catalytic converter is operating within a target temperature range based on the thermal energy residual. Related control methods are also provided.Type: GrantFiled: February 27, 2009Date of Patent: January 29, 2013Inventors: Lan Wang, Robert J.

Patent number: 8355856Abstract: An engine control system of a vehicle comprises a reserves module and a fault diagnostic module. The reserves module controls airflow into an engine based on a driver torque request, increases the airflow into the engine when a reserve torque request is received, and outputs a torque output command for the engine based on the driver torque request. The fault diagnostic module selectively diagnoses a fault in the reserves module when the torque output command is greater than a sum of the driver torque request, a predetermined torque, and a load applied to the engine.Type: GrantFiled: February 6, 2009Date of Patent: January 15, 2013Inventors: Timothy J. Hartrey, Christopher E. Whitney, Jinchun Peng, Cheryl A. Williams, Richard B. Jess

Patent number: 8209102Abstract: An engine control system comprises a pedal torque request module, a filtering module, a selection module, and an arbitration module. The pedal torque request module determines a first pedal torque request at a first time and determines a second pedal torque request at a second time. The first time is before the second time. The filtering module determines a filtered pedal torque request based on the first pedal torque request, the second pedal torque request, and a filter coefficient. The selection module selects one of the second pedal torque request and the filtered pedal torque request. The arbitration module arbitrates between at least one driver torque request and the selected one of the second pedal torque request and the filtered pedal torque request, outputs a raw driver request based on a result of the arbitration, and controls at least one engine actuator based on the raw driver request.Type: GrantFiled: January 18, 2010Date of Patent: June 26, 2012Inventors: Lan Wang, James L. Worthing, Jinchun Peng, Robert D Peavyhouse, Zhong Wang

Patent number: 8181627Abstract: An engine system includes a throttle actuator module and a torque control module. The throttle actuator module controls a throttle actuator based on a desired throttle area. The torque control module determines an actuator torque. The torque control module determines a rate limited torque, a maximum torque, and a minimum torque based on the actuator torque and a predetermined rate of change. The torque control module determines the desired throttle area based on the actuator torque when the rate limited torque is greater than the maximum torque. The torque control module determines the desired throttle area based on the actuator torque when the rate limited torque is less than the minimum torque.Type: GrantFiled: February 9, 2009Date of Patent: May 22, 2012Inventors: Kevin T.

Patent number: 8160796Abstract: An engine control system comprises a driver axle torque request module (DATRM) and a driver axle torque security module (DATSM). The DATRM determines a pedal torque request based on minimum and maximum scaling torques and a torque scalar. The DATRM determines a raw driver torque request. The DATRM selectively shapes raw driver torque request into a final driver torque request. The DATRM converts the final driver torque request into a first axle torque request. The DATSM selectively diagnoses a fault in the first axle torque request based on a minimum engine torque, the minimum scaling torque, a first comparison of the final driver torque request and the redundant final driver torque request, and a second comparison of the first axle torque request and a redundant axle torque request.Type: GrantFiled: September 23, 2009Date of Patent: April 17, 2012Inventors: Joseph M. Stempnik, Ronald W. Van Diepen, Jinchun Peng, Mark H. Costin, Bryan D Lehman, Xuehan Kong, Jonathan Packard
