Control unit of automatic transmission |
摘要 |
A control unit for an automatic transmission provides improved responsiveness to a speed reduction operation by the driver. The control unit includes a speed reduction requirement judging logic which judges whether or not there is a speed reduction requirement. An up-shift is inhibited and prevented when a judgement is made that there is a speed reduction requirement, based at least in part on release of the accelerator. Accordingly, it is possible to prevent a vehicle from being accidentally accelerated by an up-shift operation and to smoothly perform a down-shift to effect an engine brake.
