Vehicle Automatic Hoist System and Method
First Claim
1. A method of operation for a control system associated with a vehicle, the vehicle comprising a hydraulic system in electronic communication with the control system, the control system performing the steps of:
- receiving an initiation signal from a remote control unit;
in response to the signal, selectively electronically actuating first and second valves in fluid communication with first and second lifting mechanisms along a fluid flow path, the first and second lifting mechanisms operative to move a hoist apparatus coupled with the vehicle between a first position and a second position in response to movement of hydraulic fluid;
controlling the flow of hydraulic fluid along the fluid flow path to move the hoist apparatus from the first position;
receiving information representative of the movement of the hoist apparatus; and
when the hoist apparatus is in the second position, actuating the first and second valves to stop movement of the first and second lifting mechanisms.

Abstract
Systems and methods for controlling a hoist apparatus on a vehicle to automatically load and unload a container. The vehicle includes a chassis, a hoist apparatus coupled with the chassis, and at least one lift mechanism operative to move the hoist apparatus with respect to the chassis in response to the flow of hydraulic fluid along a fluid flow path. The vehicle also includes at least one valve in fluid communication with the at least one lift mechanism, a control system in electronic communication with the at least one valve, and a transceiver in electronic communication with the control system. The control system is operative to receive, via the transceiver, an initiation signal from a remote control unit. Further, the control system is operative to selectively actuate the at least one valve in response to the initiation signal to move the hoist apparatus.
