Publication number: 20180080553Abstract: The present invention is related to a vehicle including a motor-generator, a transmission, a shift hydraulic control unit, and a CVT control unit (CVTCU). When a downshift of the transmission is performed without an acceleration request from a driver, the CVTCU sets a pulley thrust at a secondary pulley on the basis of a first lower limit as a lower limit, which is a sum of a fundamental thrust and a first correction thrust. The CVTCU also sets a pulley thrust at a primary pulley on the basis of a second lower limit as a lower limit, which is a sum of the fundamental thrust and a second correction thrust.Type: ApplicationFiled: February 18, 2016Publication date: March 22, 2018Applicants: JATCO Ltd, NISSAN MOTOR CO., LTD.Inventors: Hiroki IWASA, Hironori MIYAISHI, Sungpil RYU, Tetsuya IZUMI
