A speed change control system for a vehicle is configured to reduce uncomfortable feeling of a driver caused by the change of the rotating speed of an engine along with the switching of a driving modevia a fixed stage mode. In the case of switching from a first CVT mode to a second CVT mode due to the requirement of increasing the driving force, the rotating speed of the engine is increased to afirst target speed from the moment of switching from the fixed stage mode to a second continuously variable speed mode, and then to a second target speed corresponding to the required driving force. The longer at least one of the first passing time (T1) and the second passing time (T2) is, the lower the first target speed is set (step S9). The first passing time (T1) is the time from the time whenthere is a requirement for increasing the driving force to the time when the fixed stage mode is switched to the second continuously variable transmission mode, and the second passing time (T2) is the time from the time when the acceleration of a vehicle is stabilized to the time when the fixed stage mode is switched to the second continuously variable transmission mode.

    本发明提供一种车辆的变速控制装置,所述车辆的变速控制装置可以对通过发动机转速伴随着经由固定级模式的行驶模式的切换发生变化而使驾驶员感到不适进行抑制。在因有使驱动力增大的要求而从第一无级变速模式向第二无级变速模式切换的情况下,在从固定级模式切换到第二无级变速模式的时刻起使发动机转速增加到第一目标转速之后,使之增加到与所要求的驱动力相应的第二目标转速,第一经过时间(T1)和第二经过时间(T2)中的至少任一经过时间越长,则将第一目标转速设定成越低的转速(步骤S9),所述第一经过时间(T1)是从有了使驱动力增大的要求的时刻起到从固定级模式切换到第二无级变速模式的时刻为止的时间,所述第二经过时间(T2)是从车辆的加速度稳定了的时刻起到从固定级模式切换到第二无级变速模式的时刻为止的时间。
