1. A truck brake apparatus having an autonomously controlled brake assembly and a human controlled brake assembly with interconnected pneumatic brake lines comprising:
a cab-mounted brake actuator arranged to be handled by the human operator and arranged to selectively deliver pressurized air to truck brakes and a trailer brake air supply;
a controller that performs autonomous braking operations in response to control inputs and that senses when a human operator is handling the actuator; and
a plurality of valves, interconnected in a pressure circuit with a pressurized air source on the truck, the pressure circuit including an emergency brake circuit and a service brake circuit, the actuator, the truck brakes and the trailer brake air supply, the plurality of valves responsive to the controller, and comprising a set of shuttle valves arranged to allow the actuator to override selective delivery of pressurized air to the truck brakes and the trailer brake air supply by implementing a max function between pressure caused by the human operator handling the actuator and pressure of the selective delivery of pressurized air from an electro-pneumatic proportional valve,
wherein the trailer brake air supply is constructed and arranged to deliver pressurized air from the pressure circuit to each of a trailer emergency brake through at least the emergency brake circuit and a trailer service brake through at least the service brake circuit.
