Abstract
A vehicle includes a friction braking system and a powertrain system including a torque machine operative to react tractive torque input from a wheel of the vehicle. A method for controlling braking in a vehicle includes monitoring operation of the powertrain system, determining a driver intended total brake torque, determining a regenerative braking capacity based upon the operation of the powertrain system, determining a regenerative braking request based upon a time-rate change in the regenerative braking capacity, and determining a motor torque command for the torque machine based upon the regenerative braking request.
