自动变速器的变速控制装置
摘要：
本发明涉及一种自动变速器的变速控制装置，其在以临时手动换档模式下进行行驶时，在难以对拨片换档开关进行操作且检测出要求减速时，自动地降档。如果将拨片换档开关的升档开关或者降档开关接通，则将变速模式设定为临时手动换档模式，并且使目标变速档Ger升档或者降档，然后执行手动辅助控制。在手动辅助控制中，根据车速V的时间微分，计算加速度α(S22)，在检测出加速度α大于或等于加速判定阈值αac后(S23)，根据加速器开度θacc的二重时间微分，计算加速踏板复位加速度β(S26)，在该加速踏板复位加速度β小于或等于加速度判定阈值βo时(S27)，使当前的目标变速档Ger自动地降档(S28)。
摘要（英）：

The invention relates to a gear shift control unit for an automatic transmission.The gear shift control unit can shift down automatically, when the gear shift control unit is set to a temporary manual shift mode, the operation of a paddle shift switch is difficult to achieve, and the need of deceleration is detected. If an up-shift switch or a down-shift switch of a paddle shift switch is turned on, a gear shift mode is set to a temporary manual shift mode, and a target transmission gear stage (Ger) is shifted up or shifted down, a manual assist control is executed.In the manual assist control, an acceleration [alpha] (S22) is calculated from a temporal differentiation of a vehicle speed (V). After it is detected that the acceleration [alpha] is larger than or equal to an acceleration determination threshold [alpha]ac (S23), an accelerator pedal return acceleration [beta] (S26) is calculated from a double temporal differentiation of an accelerator opening degree [theta]acc. When the accelerator pedal return acceleration is smaller than or equal to another acceleration determination threshold [beta]o (S27), the current target transmission gear stage (Ger) is automatically shifted down.
