A method of determining, during a clutch re-engagement process, the kiss-point of a vehicle clutch (14) having a driven plate (40) which drives a vehicle from an engine (10) via a multi-ratio transmission (12). The clutch is operated via a clutch actuating mechanism (20, 22) under the control of an electronic control means (36) using a method comprising the steps of: checking that the throttle (18) of the engine is closed and that the vehicle is in an engine overrun condition; partially reengaging the clutch (14) up to a point (Y) where the clutch increases the engine speed to a substantially constant level below the speed of the driven plate (40) of the clutch; measuring (34) the position of the clutch actuating mechanism (20, 22) when in said partially engaged condition; computing from said position measurement(s) and the known engagement/torque characteristics (T1, T2, T3) of the clutch the current kiss-point position (T); saving said current kiss-point position (T), and completing the engagement of the clutch.
