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 comprising:
by a controller,
generating and outputting a command to provide current to a clutch system to mechanically couple an electric machine and transmission based on received data indicative of a target clutch pressure and transmission line pressure; andaltering the command based on received data indicative of actual clutch pressure such that the actual clutch pressure is maintained equal to the target clutch pressure as the transmission line pressure varies.
