System and method of determining completion of piston stroke in automatic transmission |
摘要 |
An automatic transmission includes a low reverse brake and a reverse clutch that are engaged at different timings to determine a selected gear position, the reverse clutch being engaged immediately before the low reverse brake to be engaged last. It is determined whether or not a piston for actuating the reverse clutch has completed its stroke up to the position where it can start actual engagement. Before determination that the piston of the reverse clutch has completed its stroke up to the position where it can start actual engagement, it is prevented to determine whether or not a piston for actuating the low reverse brake has completed its stroke up to the position where it can start actual engagement.
