| 20090222191 | METHOD AND APPARATUS FOR LIMITING WHEEL SLIP - An engine control system comprises an engine speed control module and an idle limiting module. The engine speed control module selectively controls an engine based on an idle speed request. The idle limiting module selectively reduces the idle speed request by an amount that is based on a wheel slip value. | 09-03-2009 |
| 20090314070 | TRANSITION FROM EXHAUST BRAKING TO EXHAUST PARTICULATE FILTER REGENERATION IN A DIESEL ENGINE - An intake throttle valve (ITV) position determination module generates a desired ITV position based on at least one of a desired airflow in a regeneration mode and an exhaust braking request in an exhaust braking mode. An ITV position limitation module generates a limited ITV position based on the desired ITV position. A transition module detects a transition from the exhaust braking mode to the regeneration mode, wherein an ITV is controlled to the limited ITV position after the transition is detected. | 12-24-2009 |
| 20100082221 | THERMAL-PROTECTION BASED ENGINE PERFORMANCE ENHANCEMENT - An engine control module includes a power module and a turbine temperature module. The power module controls engine power output based on a turbine temperature. The turbine temperature module determines the turbine temperature based on a turbine inlet temperature. The power module decreases the engine power output when the turbine temperature is greater than or equal to a predetermined threshold temperature. | 04-01-2010 |
| 20100258080 | VARIABLE EXHAUST BRAKE CONTROL VIA TURBINE VANE POSITIONING - A control system comprising a brake torque determination module that determines a desired brake torque and a vane position determination module that determines a vane position based on an engine speed and the desired brake torque, and that adjusts the vane position to a position between an open position and a closed position. A method comprising determining a desired brake torque, determining a vane position based on an engine speed and the desired brake torque, and adjusting the vane position to a position between an open position and a closed position. | 10-14-2010 |
| 20110011081 | EXHAUST BRAKES - An exhaust brake control system includes a braking torque estimation module that estimates a desired braking torque based on engine speed. A volume flow rate determination module determines a desired volume flow rate of an exhaust gas based on the desired braking torque. An adjustment module adjusts an actual volume flow rate to control actual braking torque based on the desired braking torque and a change in exhaust temperature. | 01-20-2011 |
| 20110066338 | DRIVELINE PROTECTION SYSTEMS AND METHODS USING MEASURED STEERING ANGLE - An engine control system comprises a limit determination module and a torque control module. The limit determination module selectively varies a torque limit based on a steering angle. The torque control module selectively limits torque output by an engine to the torque limit. | 03-17-2011 |
| 20110067396 | PRESSURE ESTIMATION SYSTEMS AND METHODS - An intake control system comprises an estimation module and a turbocharger control module. The estimation module receives one of a first pressure within an intake manifold measured by a manifold pressure sensor and a second pressure measured by a pressure sensor at a location between a compressed air charge cooler and a throttle valve. The estimation module estimates the other one of the first and second pressures based on the received one of the first and second pressures. The turbocharger control module controls output of a turbocharger based on the estimate of the other one of the first and second pressures. | 03-24-2011 |
