Overdrive Control Function

The overdrive will sometimes be cut off on hills during cruise control driving. When the hill climbing hills stops, as determined by the throttle opening degree information, control will be reset to the overdrive condition after the overdrive timer has reset.

Also, when the overdrive is cut off during accelerator control or resuming control, control is returned to the overdrive condition when the accelerator control and resuming control have finished.
