    • In a control apparatus for an automatic transmission having multiple speeds constituted by four sets and speed selecting mechanisms corresponding to the four sets, assuming the speeds as seven among eight speeds of A to H in order of gear ratio, the four sets are constituted by a first set of A having a largest gear ratio and C that is next but one; a second set including at least H having a smallest gear ratio; a third set of B and D between two of the first set; and a fourth set including two of E, F and G between the second and third sets, and one of first and second pressure regulators selectively supplies hydraulic pressure to two of the mechanisms corresponding to the first and second sets, while the other thereof selectively supplies hydraulic pressure to two of the mechanisms corresponding to the third and fourth sets.

    • When slipping is generated during the upshifting from a first gear shift stage to a second gear shift stage on ice or the like, a control for prohibiting the upshifting from the second gear shift stage to a third gear shift stage can be carried out precisely. A control system is designed so that when a slipping state is detected on ice having a lower road surface friction coefficient by a slipping state determining device, the upshifting of an automatic transmission from a second gear shift stage to a third gear shift stage is prohibited. In this control system, the time required for the upshifting from a first gear shift stage to the second gear shift stage is measured. If such time is shorter than a first predetermined time, it is determined that a slipping has been generated during the upshifting, and the upshifting from the second gear shift stage to the third gear shift stage is prohibited for a second predetermined time. Thus, even when the determination of the slipping state by the slipping-state determining device is not in time, the further upshifting of the automatic transmission is prohibited. Therefore, it is possible to reliably avoid the carrying-out of undesirable upshifting.
    • 在从第一变速级升档到第二变速级在冰等上升档时产生滑动时,可以精确地执行用于禁止从第二档位升档到第三档位的升档的控制。 控制系统被设计成使得当通过滑动状态确定装置在具有较低路面摩擦系数的冰上检测到滑动状态时,禁止将自动变速器从第二换档级升档到第三档位。 在该控制系统中,测量从第一档位到第二档位的升档所需的时间。 如果这样的时间短于第一预定时间,则确定在升档期间已经产生滑动,并且在第二预定时间内禁止从第二换档级到第三档位的升档。 因此,即使当滑移状态确定装置的滑动状态的确定不及时时,禁止进一步升高自动变速器。 因此,可以可靠地避免不希望的升档。
