Abstract
A control system and method for a vehicle manual transmission system comprising a shiftlock system determines a maximum measured wheel speed of a plurality of measured wheel speeds, estimates a speed of an input shaft of the manual transmission system based on a measured output shaft speed, the maximum measured wheel speed, and a set of known parameters of components of the vehicle connected between a flywheel coupled to an output shaft of a torque generating system and the vehicle wheels, and when the estimated input shaft speed of the manual transmission system is greater than a threshold speed for a threshold period, commands the shiftlock system to restrict the engagement of a set of gear ratios of the manual transmission system.
