• Abstract This paper focuses on the engagement process of face-dog clutches on heavy duty automated mechanical transmissions (AMTs) considering special engagement conditions caused by the actuation of an electro-pneumatic transmission brake. A dynamic model of the transmission brake—single face-dog clutch system is developed and the engagement probability map characterizing the engagement capability of face-dog clutches under different engagement conditions is determined through numerical simulations for different gears of a given AMT. A region of engagement conditions is recognized where the engagement of the face-dog clutch is not ensured. Parameters influencing that region are highlighted. Optimal engagement conditions providing major gearshift comfort are given for the cases of stopped and moving vehicles. Simulation results are partly validated through statistical evaluation of measurement data obtained from a series of measurements performed on a gearbox test bench.
