Method for idle rattle abatement

A method for reducing gear rattle in a vehicle transmission system comprising a fuel controlled engine having an output shaft, a gear change transmission having an input shaft driven by said engine and an output shaft, a controller for receiving a plurality of input signals including (i) a first input signal indicative of the transmission engagement state, and (ii) a second input signal indicative of the rotational speed of the engine output shaft, said processor for processing said signals in accordance with logic rules to issue command output signals to system actuators for controlling a wet clutch, said method comprising:

• determining a transmission engagement state corresponding to the value of said first signal;
• comparing said second signal corresponding to an engine output shaft rotational speed to an idle state reference value;
• and
• if said transmission engagement state indicates neutral, and if engine output shaft rotational speed signal is less than said idle state reference value, causing said logic to dampen torque fluctuations acting upon the transmission input shaft.
