Control system for dual boom machine
First Claim
1. A control system, comprising:
- a first linkage arrangement;
a first actuator configured to move the first linkage arrangement;
a first interface device configured to generate first actuator signals indicative of operator desired movements of the first actuator;
a second linkage arrangement;
a second actuator configured to move the second linkage arrangement;
a second interface device configured to generate second actuator signals indicative of operator desired movements of the second actuator;
an input device selectively activated by the operator to generate a mode signal indicative of a desire for the first actuator and the second actuator to be controlled cooperatively; and
a controller in communication with the first interface device, the second interface device, and the input device, the controller configured to;
selectively generate commands to move the first actuator in response to only the first actuator signals;
selectively generate commands to move the second actuator in response to only the second actuator signals; and
in response to the mode signal, selectively generate commands to move both the first actuator and the second actuator in response to only the first actuator signals.

Abstract
A control system is disclosed for use with a machine. The control system may have a first linkage arrangement, a first actuator, a first interface device, and a first control element. The control system may also have a second linkage arrangement, a second actuator, a second interface device, and a second control element. The control system may further have an input device selectively activated to generate a mode signal, and a controller. The controller may be configured to selectively generate commands directed to the first control element based on only the first actuator signals, and to selectively generate commands directed to the second control element based on only the second actuator signals. The controller may also be configured to selectively generate commands directed to both of the first and second control elements based on only the first actuator signals an in response to the mode signal.

13. A method of controlling a machine having first and second linkage arrangements, the method comprising:
-
receiving first actuator signals from a first interface device indicative of desired movements of the first linkage arrangement; selectively generating commands causing movements of only the first linkage arrangement in response to only the first actuator signals; receiving second actuator signals from a second interface device indicative of desired movements of the second linkage arrangement; selectively generating commands causing movements of only the second linkage arrangement in response to only the second actuator signals; receiving input indicative of a desire to operate in a cooperative mode; and in response to the input, selectively generating commands causing movements of both the first and second linkage arrangements in response to only the first actuator signals. - View Dependent Claims (14, 15, 16, 17)
