In order to control vehicle shuffle, ie undesired fore and aft oscillations of the vehicle, the invention discloses a method comprising the steps of: continuously sensing the speed of the vehicle motor and producing a signal representing the speed analysing the speed signal determining a mean value for the speed signal identifying fluctuations from the mean value filtering the signal to remove the mean value and to retain the fluctuations applying a phase change to the filtered signal applying a deadband such that signals below a predetermined magnitude are ignored amplifying the filtered and phase changed signal resulting from the deadband application, and supplying the filtered, phase changed and amplified signal to a controller which controls the torque output of the vehicle motor.
A method of controlling undesired fore and aft oscillations of a motor vehicle, the method comprising the steps of:
An engine management system for a motor vehicle, which system is adapted to receive an engine speed signal from an engine speed sensor and to output a torque control signal to an engine torque controller, the system comprising:
