Abstract

A concrete mixer vehicle includes a chassis, a mixing drum assembly, and a controller. The mixing drum assembly includes a mixing drum, a mixing element, a collector, and a chute. The mixing drum defines an aperture and a volume. The mixing element is positioned within the volume and is coupled to the mixing drum. The controller is configured to determine a state of the concrete mixer vehicle, determine a state of a mixture delivery system of a batch plant, obtain and apply a setpoint value to an actuator of the concrete mixer vehicle or the mixture delivery system, and activate the mixture delivery system to output material through the outlet of the mixture delivery system such that the material is deposited directly into the volume of the mixing drum to thereby directly charge the concrete mixer vehicle with material.

a collector positioned to receive the material from the mixing drum; and
a chute positioned to receive the material from the collector; and
a controller configured to:
determine a state of the concrete mixer vehicle;
determine a state of a mixture delivery system of a batch plant; and
based on the state of the concrete mixer vehicle and the state of the mixture delivery system: (i) obtain a setpoint value for an actuator of the concrete mixer vehicle or the mixture delivery system, the setpoint value associated with a position of the actuator such that an outlet of the mixture delivery system is disposed within the volume, (ii) apply the setpoint value to the actuator of the concrete mixer vehicle or the mixture delivery system to position the outlet of the mixture delivery system within the volume, and (iii) activate the mixture delivery system to output material through the outlet of the mixture delivery system such that the material is deposited directly into the volume of the mixing drum to thereby directly charge the concrete mixer vehicle with the material.

2 . The concrete mixer vehicle of claim 1 , further comprising:
