SPEED CHANGE RATIO CONTROL DEVICE OF CONTINUOUSLY VARIABLE TRANSMISSION FOR VEHICLE

摘要

PURPOSE:To hold down pitching to the minimum by obtaining a correction factor of a speed change ratio of a continuously variable transmission according to the operating condition of a brake device special for a driven wheel to correct the target speed change ratio in a motor cycle. CONSTITUTION:Calculating means 201 for the target speed change ratio of a speed change ratio control device 200 obtain a basic target speed change ratio of a continuously variable transmission T from information of detection means for detecting the normal running condition. A detection signal of the first brake sensor Sg is input to calculating means 202, the calculating means obtains a corresponding correction factor according to the operating condition of a brake device special for a driven wheel, and the target speed change ratio is corrected by correction means 203. A detection signal of the second brake sensor Sd is input to correction factor calculating means 202 to obtain a correction factor considering control input of a brake device special for a driving wheel as well as that of the brake device special for a driven wheel. Thus, pitching can be held down to the minimum.
