ABSTRACT:
In a device for performing the control during acceleration in a continuously variable transmission system for a vehicle, wherein a speed ratio e of the continuously variable transmission system is controlled such that an actual engine rotational speed Ne can be a target engine rotational speed Ne', a predetermined value Nb lower than Ne' and a predetermined vale N.times.3 slightly higher than Nb are set, the shift in the continuously variable transmission system is interrupted until Ne is increased to a predetermined value higher than Ne' when Ne enters a state of Nb<Ne.ltoreq.N.times.3, and the speed ratio e of the continuously variable transmission system is continuously raised until Ne is decreased to a state of Ne.ltoreq.N.times.3 when Ne is changed from a state of Ne>Ne' to a state of Ne<Ne', so that the device can maintain a satisfactory acceleration, suppress the decline of a transmission efficiency and reduce the noise level during acceleration.
