System and method of preventing articulated machine roll-over
First Claim
1. A method of preventing an articulated machine from rolling over, the articulated machine having a first frame and a second frame, the method comprising:
- receiving a position of the first frame from a first sensor provided on the first frame and a position of the second frame from a second sensor provided on the second frame;
determining a relative position of the second frame with respect to the first frame by comparing the position of the first frame and the position of the second frame received from the first sensor and the second sensor;
comparing the determined position of the second frame with a predefined position limit; and
automatically locking an inter axle differential between the first frame and the second frame when the determined position of the second frame is greater than the predefined position limit.

Abstract
An articulated machine having a first frame and a second frame supported by first and second wheel assemblies respectively is provided. The machine includes a first sensor and a second sensor to provide position information of the first frame and the second frame respectively. The machine includes a drive train to couple the front and rear wheel assembly, and having an inter axle differential to facilitate the front and the rear wheel assembly to move at different speeds. The machine includes a controller to compare position of the first frame with position of the second frame to determine relative position of the second frame with respect to the first frame. The controller compares the relative position of the second frame with a predefined position limit. The controller selectively locks the inter axle differential when the determined relative position of the second frame is greater than the predefined position limit.

11. An articulated machine comprising:
-
a first frame supported by a front wheel assembly; a second frame supported by a rear wheel assembly; a first sensor provided on the first frame and configured to provide a position of the first frame; a second sensor provided on the second frame and configured to provide position information of the second frame; a drive train configured to couple the front and the rear wheel assembly, the drivetrain having an inter axle differential configured to facilitate the front and the rear wheel assembly to move at different speeds; and a controller operatively coupled to the sensors and the inter axle differential, the controller being configured to; compare the position of the first frame received from the first sensor with the position of the second frame received from the second sensor to determine a relative position of the second frame with respect to the first frame; compare the determined relative position of the second frame with a predefined position limit; and selectively lock the inter axle differential when the determined relative position of the second frame is greater than the predefined position limit. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)
