Abstract: A method of estimating the oxygen storage capacity of a catalyst includes providing an engine system having an internal combustion engine and an exhaust system having a catalyst and an oxygen sensor, providing a three-way catalyst observer model having a Kalman filter and a three-way catalyst kinetic model, estimating a three-way catalyst next time step state and a modeling error, linearizing the three-way catalyst observer model, filtering the estimated three-way catalyst next time step state, and calculating a covariance.

Abstract: A transmission includes an input and output member, four planetary gear sets each having first, second and third members, five interconnecting members continuously interconnecting members of the four planetary gear sets and six torque transmitting mechanisms selectively engageable to interconnect one of the first members, second members, and third members with at least one of another of the first members, second members, third members, and a stationary member. The torque transmitting mechanisms are selectively engageable in combinations of at least three to establish at least eight forward speed ratios and at least one reverse speed ratio between the input member and the output member.

Abstract: An automated electric manual transmission (EMT) has an input member, an output member, and at least one shaft. The input member and the at least one shaft are rotatable about a first axis of rotation. A countershaft is substantially parallel with the at least one shaft and is rotatable about a second axis of rotation. The output member is operatively connected to rotate with the countershaft. A transmission controller controls engagement of a plurality of torque-transmitting mechanisms to selectively establish different gear ratios from the at least one shaft to the transfer shaft through pairs of intermeshing gears. An electric motor and a planetary gear set are concentric with the first axis of rotation. The electric motor can provide torque to a member of the planetary gear set.
