    Abstract: A method to monitor a torque transfer device configured to transfer torque within an electro-mechanical transmission mechanically-operatively coupled to an internal combustion engine and at least one electric machine includes executing a failure detection strategy in response to a detected slip condition of the torque transfer device. The failure detection strategy includes monitoring a magnitude of energy loss of the torque transfer device. A failure condition in the torque transfer device is detected when the magnitude of energy loss achieves a predetermined energy threshold.

    Abstract: A method and system for controlling the overall brake bias in a vehicle braking system having both frictional and regenerative braking devices. The method comprises receiving a brake bias command and determining a desired brake bias based on the brake bias command. The method further comprises changing the brake bias in the vehicle braking system to achieve the desired brake bias through the operation of one or more regenerative braking devices. The system comprises one or more regenerative braking devices, each configured to apply negative torque to one of a first axle or a second axle of the vehicle, and an electronic module, for example, an electronic brake control module (EBCM) that is configured to perform the above-described methodology.
