A method for and apparatus for preventing oscillations of a vehicle. The engine speed is monitored and filtered, the filtered engine speed being compared to a natural frequency of the vehicle. The natural frequency corresponds to a gear ratio of the vehicle. A torque command is provided to an electric machine coupled to a driveline of the vehicle, the electric machine provides a counteracting torque to the driveline in order to eliminate oscillations in the vehicle.

Apparatus and method for smoothing of vehicle drivelines

A neural network characterized by a minimal architecture suitable for implementation in conventional microprocessor battery pack monitoring hardware includes linear and non-linear processing elements and battery parameter measurements representative of real time and temporal quantities whereby state of charge estimations actually converge with 100% and 0% states-of-charge.

Method and apparatus for determining battery state-of-charge using

A method for diagnosing the general condition of a battery module in a string of such modules comprising a battery pack monitors voltage, current and temperatures of the modules and battery pack. Accumulators account for various charge quantities including charge out and net charge used for the battery pack as well as discharge period durations. State of charge is provided by appropriate means and used to update module capacities. The various charge and time accumulators are used to derive depth of discharge and discharge rate information providing inputs to predetermined functions for determining a simple scalar outputs directly indicative of the general condition of the modules.
