Abstract: Systems and methods for supplying feedback to a driver of a vehicle so that transmission shifting busyness may be reduced are presented. In one example, the systems and methods include increasing resistance of an accelerator pedal in response to a difference between an available powertrain torque and a desired powertrain torque.

Abstract: An internal combustion engine having a plurality of combustion cylinders configured to operate in a compression ignition mode. A pressure sensor is provided to sense pressure within a combustion cylinder of the engine. A combustion control system, including an electronic engine controller, is configured to receive electrical signals from the pressure sensor and, based on such signals, determine a maximum rate of pressure increase occurring in the combustion cylinder during a first time interval. Based on the determined maximum rate of pressure increase, the combustion control system is configured to control one or more charge inputs to the combustion cylinder during a second time interval.

Abstract: A method and apparatus for accurately determining the previously applied torque to a threaded fastener. Torque is increasingly applied to the fastener and measured periodically. The measurements are digitized and stored in a microprocessor. The torque previously applied is the torque that causes the fastener to breakaway or start to begin to turn. This breakaway point is the torque corresponding to a change in the slope of the applied torque-time relationship. The breakaway point is determined by determining the maximum different value between the measured torque and a mathematical line segment commencing from below the breakaway point and extending to the peak torque applied. The breakaway point (or applied torque) is the torque corresponding to the calculated maximum difference value.
