Abstract
Systems to control movement of a motor grader include a sensor for providing a bounce signal indicative of a bouncing movement of the motor grader, and a controller programmed with instructions that, when executed: receive the bounce signal from the sensor; analyze the bounce signal from the sensor; determine whether the maximum amplitude of the bouncing movement exceeds a threshold; in response to determining whether the maximum amplitude exceeds the threshold, generate an articulation angle command signal to change an articulation angle of the motor grader; and transmit the articulation angle command signal to change the articulation angle.
Claims20
A method for controlling movement of a motor grader, the motor grader including a front frame and a rear frame, wherein the front frame is configured to articulate relative to the rear frame about an articulation angle;
- the method comprising:
- receiving, at a controller, a bounce signal from a first sensor, wherein the signal is indicative of a bouncing movement of the motor grader;
- analyzing, by the controller, the bounce signal from the first sensor, wherein analyzing the bounce signal comprises determining a maximum amplitude of the bouncing movement of the motor grader based on the bounce signal from the first sensor and determining whether the maximum amplitude exceeds an amplitude threshold;
- in response to determining whether the maximum amplitude exceeds the amplitude threshold, generating, by the controller, an articulation angle command signal to change the articulation angle;
- and
- transmitting the articulation angle command signal from the controller to change the articulation angle.
A system for automated control of movement of a motor grader, the motor grader including a front frame and a rear frame, wherein the front frame is configured to articulate relative to the rear frame about an articulation angle, the system comprising:
- a first sensor carried by the motor grader and configured to provide a bounce signal indicative of a bouncing movement of the motor grader;
- and
- a controller programmed with instructions that, when executed:
- receive the bounce signal from the first sensor;
- analyze the bounce signal from the first sensor, wherein analyzing the bounce signal comprises determining a maximum amplitude of the bouncing movement of the motor grader based on the bounce signal from the first sensor;
- determine whether the maximum amplitude exceeds an amplitude threshold;
- in response to determining whether the maximum amplitude exceeds the amplitude threshold, generate an articulation angle command signal to change the articulation angle;
- and
- transmit the articulation angle command signal from the controller to change the articulation angle.
