Speed change control device for automatic transmission and control method thereof |
摘要 |
<p>A speed change control device for an automatic transmission according to this invention determines whether or not a request to downshift a gear position of the transmission exists during traveling in a manual speed change mode (S1, S2), and calculates an input shaft rotation speed of the transmission following a downshift based on the downshift request (S4). When it is determined that the calculated rotation speed is higher than a rotation speed limit value (S5), the speed change control device performs a downshift to a gear position at which the input shaft rotation speed of the transmission is lower than the calculated rotation speed (S6, S8).</p> |
