Abstract

PURPOSE: To prevent the comfortableness of ride from being impaired due to unnecessarily repeated speed changes by a method wherein a hysteresis is provided for an up-shift line after a down-shift when the positive change rate of the throttle opening at the time of a kickdown is low.
CONSTITUTION: When the change rate of the throttle opening at the time of transfer into a kickdown range is low, this condition is detected by a comparing circuit 12 which then feeds a high-level signal into an AND circuit 15. On the other hand, a comparing circuit 10 detects the kickdown condition where the throttle opening becomes not less than θ1 and feeds a high-level signal to the AND circuit 15, which feeds a high-level signal to a set input terminal S of a modifying circuit 13. Accordingly, the circuit 13 feeds a high-level signal to the circuit 10, which modifies the comparison level from the value corresponding to the throttle opening of θ1 to the value corresponding to a throttle opening of θ2.
