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.

1. A vehicle comprising:
an electric machine; a transmission; a clutch system configured to
receive a current having a magnitude that depends on a line pressure associated with the transmission, andcontrol a clutch pressure to mechanically couple the electric machine and transmission based on the magnitude; and a controller configured to alter the magnitude based on the clutch pressure such that the clutch pressure remains generally equal to a target as the line pressure varies.
