Device for performing control during acceleration continuously variable transmission system for vehicle

A device for performing the control during acceleration in a continuously variable transmission system for a vehicle, wherein a speed ratio e of said continuously variable transmission system is controlled such that an actual engine rotational speed Ne can be a target engine rotational speed Ne', comprising:

• processor means for performing the functions of, setting a predetermined value Nb lower than said Ne' and a predetermined value N.times.3 slightly higher than Nb,
• detecting whether a difference between Ne' and Nb is large or not,
• generating a signal for controlling interrupting, when Ne enters a state of Nb<Ne.ltoreq.N.times.3, changes in the speed ratio of said continuously variable transmission system until Ne is increased to a predetermined value equal to or higher than Ne', and
• generating signals for controlling continuously raising the speed ratio e of said continuously variable transmission system until Ne is decreased to a state of Ne.ltoreq.N.times.3 when the difference between Ne' and Nb is large and Ne is changed from a state Ne.ltoreq.Ne' to a state of Ne<Ne';
• and
• means for varying said speed ratio e under control of the signals generated by said processor means.

• processor means for performing the functions of,
• setting a predetermined value N.times.1 higher than said Ne',
• generating signals for controlling the variation value .DELTA.e of said speed ratio e to be at a small value when said Ne is in a state of Ne'<Ne<N.times.1, and
• generating signals for controlling the variation value .DELTA.e of said speed ratio e to be at a large value when said Ne is in a state of Ne>N.times.1;
• and
• means for varying said speed ratio e under control of the signals generated by said processor means.
