SYSTEMS AND METHODS FOR BRAKE TORQUE DISTRIBUTION

A vehicle system can comprise a vehicle chassis with or more primary axles and one or more auxiliary axles, a powertrain comprising at least one electric motor coupled to the primary axles, a friction braking system comprising a plurality of friction brakes, where each friction brake is coupled to a respective wheel on each of the primary and auxiliary axles, and a controller. The controller includes computer-readable instructions for: in response to a deceleration request and predetermined vehicle operating conditions for operation in a tire life mode being met, actuating a first portion of the friction brakes to apply a first brake torque to the auxiliary axles and actuating the electric motor and a second portion of the friction brakes to apply a remaining, second brake torque to the primary axles. The first brake torque is greater than the second brake torque.
