Claims

[Scope of utility model registration request]

A vehicle speed detection means, a throttle valve opening detection means, a shift pattern in which an automatic shift point is stored in correspondence with the vehicle speed and a throttle valve opening, and at least the throttle valve opening among the parameters used to calculate the automatic shift point. a rewritable automatic shift point conversion table in which the relationship between the actual value and the control value is stored; a data correction means for correcting and rewriting the automatic shift point data in the conversion table based on predetermined learning; A converting means for referring to a control throttle opening corresponding to a detected throttle opening, and a shift switching means for controlling the automatic transmission to shift at an automatic shift position of a shift pattern according to the referenced control throttle opening. A speed change control device for an automatic transmission for a vehicle, characterized in that:
