Abstract: A concrete mixer vehicle includes a mixer drum, an additive admixture system, and a controller. The additive admixture system includes an air inlet valve, a fluid valve, an air valve, and a pump. The controller is configured to operate the additive admixture system to transition the additive admixture system between an additive addition mode, a drain mode, and a system clear mode. The controller transitions the additive admixture system into the additive addition mode and operates the pump until a desired amount of an additive is added to the mixer drum, transitions the additive admixture system into the drain mode for a predetermined amount of time in response to the desired amount of additive being added to the mixer drum, and transitions the additive admixture system into the system clear mode for a predetermined amount of time to clear stagnant fluid or built up mixture from the additive admixture system.

Abstract: A vehicle includes a prime mover, a mixer drum assembly configured to selectively discharge a contents thereof, and a control system having a sensor. The control system is configured to detect, via the sensor, a state of a receiving device that is configured to receive the contents discharged from the mixer drum assembly, determine a desired state of the receiving device, adjust a vehicle state to reduce a difference between the state of the receiving device and the desired state of the receiving device, and cause a presentation of an indication of the adjustment of the vehicle state.

Abstract: A concrete mixer vehicle includes a mixer drum assembly, an energy storage device, an internal combustion engine, an auxiliary power unit, and an energy management controller. The internal combustion engine is configured to supply power to the mixer drum assembly. The auxiliary power unit is configured to supply power from the energy storage device to the mixer drum assembly. The energy management controller is configured to engage the APU and disengage the ICE based on a state of charge of the energy storage device.
