Abstract

An engine and a second power generating device transmit power through a transmission to a driveline to a wheel. A control module determines a regenerative braking axle torque capacity and a regenerative braking torque. Power output from the second power generating device is controlled based upon a regenerative braking axle torque request. A brake control module determines a total braking torque request and generates the regenerative braking axle torque request based upon the total braking torque request, the regenerative braking axle torque capacity, and the regenerative braking torque. The brake control module controls a friction brake.
