    Abstract: A method and system for controlling engine speed during a vehicle launch (from a rest condition to a moving condition), such vehicle having the engine is coupled to an automatic shifting manual transmission. The method comprises determining a spark timing offset based on one or more of engine speed, a time rate of engine speed, relative air charge, engine coolant temperature, accelerator pedal position, and a time rate of change of accelerator pedal position. A new spark timing is determined as the base spark timing minus the spark timing offset. By adjusting spark timing based primarily on a time rate of change of engine speed, engine speed fluctuations arising during a clutch engagement associated with vehicle launch are largely attenuated.

    Abstract: Systems and methods for estimating the bias and scale factor in a speed sensor and pitch sensor using a modified adaptive filter. A filter learns adaptively in a random manner to estimate the errors in the vehicle speed and pitch angle. The aiding measurements used in this approach are exemplarily DGPS travel distances. The filter adaptively estimates error source values during the availability of DGPS, and can then use these estimates to aid an INS during DGPS outages.

    Abstract: The present invention discloses a method for reducing NOx in exhaust gases of an internal combustion engine. The purpose of this invention is to convert engine out NOx (approximately 90% NO in diesel exhaust) into roughly a 50:50 mixture of NO and NO2, while simultaneously oxidizing engine-out hydrocarbons which interfere with the reduction of NOx by urea or ammonia. The present invention demonstrates that a 50:50 blend of NO and NO2 is reduced more rapidly and with higher efficiency than a gas stream which is predominantly NO. In addition, catalyst in an engine exhaust that is a 50:50 mixture of NO and NO2 is far more resistant to hydrothermal deterioration than using NO alone. In another embodiment of the present invention, a vehicle exhaust system utilizing the method of the present invention is provided.

    Abstract: A magnetorheological (MR) vibration damper for damping axial and rotational vibrations of an automotive steering system may include a housing encasing MR fluid therein and a gear-like rotor and orifice plate disposed within the housing. The rotor and orifice plate, which may be affixed to the steering wheel shaft, includes a plurality of gear-like teeth on its surface and a plurality of holes for producing shear and normal forces, respectively, on the MR fluid. Electric coils may be disposed within the housing for generating an electric field for activating the MR fluid. The MR vibration damper may be activated or deactivated by a controller by comparing a signal value from a steering wheel vibration sensor to a predetermined threshold value. The controller may be programmable by a user to increase or decrease the predetermined threshold value, so as to enable customization of driving feel.
