Abstract
A hierarchical control system for a tandem axle assembly for a vehicle is provided. The hierarchical control system includes a vehicle level controller, an actuator, a shift controller, and a sensor. The shift controller is capable of placing the tandem axle assembly in at least a first operating condition and a second operating condition using the actuator. In response to the sensor and an operating condition of at least one of the power source and the transmission of the vehicle, the shift controller adjusts a manner of placing the tandem axle assembly in at least one of the first operating condition and the second operating condition. The hierarchical control system facilitates performing a shifting procedure in an automatic manner or as desired by an operator of the vehicle without excessively increasing a cost and a complexity of the tandem axle assembly.
