METHOD OF CONTROLLING SHIFTS IN AN AUTOMATIC TRANSMISSION

摘要

When a first shift command is issued, the input and output rotational speed ratio (eCLa) of a shift means associated with a first target speed range (Sa) for selecting a power transmission path associated with the first target speed range (Sa) and determined by the first shift command is detected, and the start of operation of the shift means associated with the first target speed range (Sa) is detected by checking whether the input and output rotational speed ratio ((eCLa) has started to vary or not. When a second gear-shift command is issued after the first shift command has been issued but before the start of operation of the shift means is detected, the second shift command is accepted.
