Abstract:
A control system for a transmission of a vehicle includes a first angular rotation module, a second angular rotation module, and a lash module. The first angular rotation module determines a first angular rotation of a first shaft during a first predetermined period based on a first signal generated by a first shaft sensor. The second angular rotation module determines a second angular rotation of a second shaft during the first predetermined period based on a second signal generated by a second shaft sensor. The lash module selectively detects lash between gears of the transmission based on the first angular rotation and the second angular rotation.
