Abstract
A controller on a tractor portion of an articulated vehicle includes an electrical input port adapted to receive an electrical input signal based on a command to unpark a trailer portion of the articulated vehicle and an electronic processor adapted to: receive the electrical input signal from the electrical input port; identify, based on the electrical input signal, when the command to unpark the trailer is received at the electrical input port; and based on the command to unpark the trailer, transmit an electrical output signal to an electrical output port for causing supplemental compressed air to be communicated from the tractor to the trailer for filling an air tank on the trailer using a quick-fill mode.
Claims7
A system of an articulated vehicle, the system comprising:
- a trailer control valve on a first portion of the articulated vehicle;
- a check valve on the first portion of the articulated vehicle;
- and
- a controller on the first portion of the articulated vehicle, the controller adapted to:
- receive an electrical input signal based on a command from a trailer park control valve to unpark a second portion of the articulated vehicle;
- identify, based on the electrical input signal, when the command to unpark the second portion of the articulated vehicle is received;
- and
- based on the command to unpark the second portion of the articulated vehicle, transmit an electrical output signal to the trailer control valve, upon receiving the electrical output signal, the trailer control valve transmitting supplemental fluid to a supply port of the check valve, and when the check valve is open the supplemental fluid being combined with primary fluid downstream of the check valve and being fluidly communicated from the first portion of the articulated vehicle to the second portion of the articulated vehicle.
