AUTOMATIC TRANSMISSION CONTROL DEVICE |
摘要 |
An automatic transmission control device of a vehicle performs a gear change operation based on a deceleration of the vehicle. The automatic transmission control device detects the deceleration of the vehicle and an engine rotational speed. The device also stores a peak value of the engine rotation speed during a period in which a vehicle travels with one predetermined gear step, and includes a relationship map showing the relationship between the deceleration and a shift-down rotational speed. The device performs an automatic shift-down when the engine rotational speed is lowered from the peak value by a predetermined rotational speed which is obtained from the map based on the deceleration.
