Abstract

Claims (32)

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 initiation 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.

2. The method of claim 1 , wherein the control system is in electronic communication with a radio frequency transmitter and a radio frequency receiver.

3. The method of claim 2 , wherein the initiation signal is received at the radio frequency receiver from a remote control and transmitted to the control system.

4. The method of claim 2 , further comprising the step of determining a distance between the vehicle and the remote control unit.

5. The method of claim 4 , further comprising the step of comparing the distance with a predetermined distance prior to electronically actuating the first and second valves.

6. The method of claim 1 , wherein the information representative of the movement of the first and second lifting mechanisms is transmitted from position sensors associated with the first and second lifting mechanisms.

7. The method of claim 1 , further comprising receiving location information from a GPS module in electronic communication with the control system.

8. The method of claim 1 , further comprising the step of receiving diagnostic information regarding the vehicle via a vehicle bus in electronic communication with the control system.

9. A vehicle comprising:

a chassis and a hoist apparatus coupled with the chassis;

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;

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;

a transceiver in electronic communication with the control system;

the control system operative to receive, via the transceiver, an initiation signal from a remote control unit;

the control system operative to selectively actuate the at least one valve in response to the initiation signal to move the hoist apparatus from a first position to a second position.

10. The vehicle of claim 9 , wherein the control system is operative to automatically load a container onto and unload a container from the vehicle by selective actuation of the at least one valve.

11. The vehicle of claim 9 , wherein the at least one valve comprises a plurality of valves.

12. The vehicle of claim 11 , wherein the plurality of valves are electrically actuated.

13. The vehicle of claim 11 , wherein the at least one lift mechanism comprises a plurality of lift mechanisms.

14. The vehicle of claim 9 , wherein the control system is in electronic communication with at least one display.

15. The vehicle of claim 9 , wherein the control system is in electronic communication with a vehicle bus.

16. The vehicle of claim 15 , further comprising a GPS module in electronic communication with the control system.

17. The vehicle of claim 16 , wherein the control system is operative to transmit, via the GPS module, diagnostic data received via the vehicle bus to a remote computer.

18. The vehicle of claim 9 , wherein the vehicle is a roll-off vehicle.

19. The vehicle of claim 9 , wherein the control system is operative to determine a distance between the remote control unit and the vehicle.

20. The vehicle of claim 19 , wherein the control system will not actuate the at least one valve in response to the initiation signal if the distance is less than a predetermined distance.
