Coordination between friction brake system, individual-wheel drive electric motors and tire inflation pressure system is considered. To coordinate vehicle subsystems, optimization-based control allocation is used. The influence of subsystem coordination on criteria of vehicle dynamics (braking distance, RMSE of longitudinal acceleration, RMSE of yaw rate, sideslip angle) and energy consumption and losses (recuperated energy during maneuver and tire energy dissipation) were analyzed for straight-line braking and brake-in-turn maneuvers by simulation investigation. The proposed control system was investigated using HIL test rig with hardware components of friction brake system and tire inflation pressure system.
