| 20080208420 | Torque control arbitration in powertrain systems - A method of regulating a torque output of a vehicle powertrain includes generating a plurality of torque requests and associating each of the plurality of torque requests with one of a plurality of arbitration domains to form torque request sets associated with each of the plurality of arbitration domains. A first torque request set is arbitrated within a first of the plurality of arbitration domains to provide a first torque request. The first torque request is introduced into a second torque request set associated with a second of the plurality of arbitration domains. The second torque request set is arbitrated within the second arbitration domain to provide a second torque request. A torque source is regulated based on the second torque request. | 08-28-2008 |
| 20090024263 | ASSOCIATION OF TORQUE REQUESTING MODULES IN A COORDINATED TORQUE ARCHITECTURE - A powertrain control system for a vehicle includes a plurality of axle torque request modules that generate respective axle torque requests based on respective performance criteria of a vehicle, an axle torque arbitration module that generates a net axle torque request based on the plurality of axle torque requests, a plurality of propulsion torque request modules that generate respective propulsion torque requests based on respective performance criteria of an engine of the vehicle, a propulsion torque arbitration module that determines a net engine torque request based on the net axle torque request and the plurality of propulsion torque requests, and a propulsion torque control module that controls a plurality of actuators based on the net engine torque request such that the engine produces an output torque in accordance with the net engine torque request. | 01-22-2009 |
| 20100242912 | METHOD AND SYSTEM FOR DETECTING AND REDUCING ENGINE AUTO-IGNITION - A method and a control module for performing the same include a filter module filtering in-cylinder pressure signals using a filter to form filtered in-cylinder pressure signals. The control module further includes a heat release rate determination module generating heat release rate signals based on the in-cylinder pressure signals and a maximum heat rate determination module determining a maximum heat release rate from the heat release rate signals. The system also includes a correction module correcting auto-ignition for the engine based on the maximum heat release rate. | 09-30-2010 |
| 20110077846 | METHOD AND SYSTEM FOR ESTIMATING AND REDUCING ENGINE AUTO-IGNITION AND KNOCK - A control system for an engine includes a heat-release rate (HRR) module, a first filter module, a second filter module, an auto-ignition energy determination module, and a corrective action module. The HRR module generates an HRR signal based on in-cylinder pressures of a cylinder of the engine. The first filter module generates a first filtered HRR signal indicative of a first HRR due to combustion in the cylinder by filtering the HRR signal. The second filter module generates a second filtered HRR signal indicative of a second HRR due to auto-ignition in the cylinder by filtering one of the HRR signal and the first filtered HRR signal. The auto-ignition energy determination module determines an auto-ignition energy of the cylinder based on the first and second filtered HRR signals. The corrective action module selectively adjusts auto-ignition of the engine based on the auto-ignition energy. A related method is also provided. | 03-31-2011 |

| 20090082702 | OBTAINING MEASUREMENTS OF MUSCLE REFLEXES FOR DIAGNOSIS OF PATIENT SYMPTOMS - A system and method is disclosed for measuring muscle reflexes (e.g., a bulbocavernosus reflex) as a tool for identifying/diagnosing dysfunctions (e.g., spinal cord abnormalities, bladder voiding dysfunction, and sexual organ dysfunction) non-invasively by using mechanical stimulation. The system and method includes a probe having a predetermined patient contacting portion, wherein when the contacting portion is moved into contact with a particular area of the patient (e.g., the patient's genitals), the contact induces a muscle reflex. The probe detects the pressure resulting from the contacting portion being abruptly and forcibly brought into contact with the particular area. Such detection is used to electronically initiate capture of electrical responses from a plurality of electrodes placed on the patient's skin in proximity to the particular area. Such electrical responses are processed to determine characteristics of the patient's reflexes of one or more muscles adjacent to the electrodes. | 03-26-2009 |
