PRESSURE CONTROLLED DRIVELINE MECHANICAL COUPLING

摘要

A vehicle includes a motive power source, a transmission, and a clutch system. The vehicle further includes a controller that causes the clutch system to generate a generally constant clutch pressure to mechanically couple the motive power source and transmission as a line pressure associated with the transmission varies.

主权项

1. A method for controlling a clutch system comprising:
providing a current to the clutch system to mechanically couple an electric machine and transmission based on a target clutch pressure and a line pressure associated with the transmission; receiving data about an actual clutch pressure; and altering the current based on the data to keep the actual clutch pressure substantially equal to the target clutch pressure as the line pressure varies.
