PURPOSE:To achieve a variable speed in a small shift shock at all times, when a fact that a power generating part is varied from 'drive' to 'driven' is detected, by emitting a shift command through a timer setting this detection time as a starting point. CONSTITUTION:During operation of a standby timer T1 for corresponding to multiplex variable speeds, if there is a variation from 'power-on' to 'power-off' as well as there is an up-shift, A T4 counter is started as setting this varied time as a starting point, and a shift output is generated at a time when this T4 counter is reached to a T4 map value selected by real time. Even if the T4 counter is reached to the T4 map value, however, the standby timer T1 itself was still in operation, the shift output is generated after the elapse of this timer T1. With this constitution, even in an earlier or late case of time ranging from the power-on to the power-off, a shift command is emitted at an optimum point of time, thus such a variable speed as small in a shift shock is realizable. |
