Process for determining the shifting time for a transmission ratio change in an infinitely variable transmission |
摘要 |
The invention relates to a process for controlling a change of the transmission ratio (ue) in an infinitely variable transmission, which simulates a stepped transmission. A basic shifting time is determined separately for each shifting position and direction. In addition, a rotational speed factor, is used to take into account the change of the rotational input speed of the transmission caused by the change of the transmission ratio, and a lead factor reflects the lead existing at the transmission input. Shifting of the infinitely variable transmission is then performed as a function of the basic shifting time, the rotational speed factor and the lead factor.
