Abstract
A vehicle control system for regulatng operation of a vehicle having a transmission includes a first module that processes an output shaft signal which is based on rotation of an output shaft of the transmission through a third order Kalman filter to determine an acceleration of the output shaft A second module calculates the acceleration of the vehicle based on the acceleration of said output shaft. A third module regulates operation of the vehicle based on the acceleration of the vehicle.

A vehicle control system for regulating operation of a vehicle having a transmission, comprising:
- a first module that processes an output shaft signal, which is based on rotation of an output shaft of said transmission, through a third order Kalman filter to determine an acceleration of said output shaft;
- a second module that calculates said acceleration of said vehicle based on said acceleration of said output shaft, and
- a third module that regulates operation of said vehicle based on said acceleration of said vehicle.
A method of determining an acceleration of a vehicle having a transmission, comprising:
- generating an output shaft signal based on rotation of an output shaft of said transmission:
- processing said output shaft signal through a third order Kalman filter to determine an acceleration of said output shaft;
- and
- calculating said acceleration of said vehicle based on said acceleration of said output shaft.
