Face dog clutches regain popularity in heavy duty AMT´s. Though the reduction of the speed difference between the dogs is the key to a smooth gear shift, the excellent engaging capability is experienced to degrade at low mismatch speed and the outcome of the engagement process becomes uncertain. Using a simple mechanical model, that uncertainty is described and the probability of the successful engagement is given as a function of the initial mismatch speed. Results are validated through statistical evaluation of measurement data.
