Abstract

A clutch control for shifting a vehicle drive system as between automatic four-wheel drive, locked four-wheel drive and two-wheel drive. An engagement system for engaging drive and driven components of the drive system may include roller clutch engagement or pawl clutch engagement. The clutch system is provided with a coupling mechanism for coupling the engagement member to ground or to the driven member to thereby achieve automatic four-wheel drive and locked four-wheel drive, respectively. The engagement member is decoupled from both ground and the driven member to achieve two-wheel drive.
