Patent number: 11739802Abstract: Clutch temperature management in a slip control method and arrangement for a drivetrain including a continuously variable transmission is described herein. The drivetrain includes a clutch that is so controlled as to slip when a torque higher than the usable torque attempts to pass through. The temperature data from the clutch is used to determine the usable torque. Accordingly, the clutch prevents the prime mover from stalling.Type: GrantFiled: May 28, 2020Date of Patent: August 29, 2023Inventors: Jonathan Guérin, Jean-François Dionne, Daniel Girard, François Messier
