Claim 9:
10. A method for automatic tilting of an operator cabin of a work machine, the work machine including a frame structure, the method comprising:
mounting the operator cabin on the frame structure, wherein the frame structure is rotatably coupled to a lower structure;
generating, by at least one first sensor coupled to the work machine, a first signal indicative of a first pitch angle of the work machine relative to a non-inclined surface;
receiving, by a controller of the work machine, the first signal indicative of the first pitch angle of the work machine;
determining, by the controller, a second pitch angle based on the first pitch angle; and controlling at least one of a first actuator of the work machine and a second actuator of the work machine to tilt the operator cabin by the second pitch angle relative to the non-inclined surface,
determining, by the controller, an uphill movement of the work machine, and generating, by the controller, a first control signal to retract each of the first actuator and the second actuator for tilting the operator cabin in an anti-clockwise direction based on the uphill movement of the work machine;
determining, by the controller, a downhill movement of the work machine, and generating, by the controller, a second control signal to extend the first actuator and retract the second actuator for tilting the operator cabin in a clockwise direction based on the downhill movement of the work machine;
wherein the first actuator defines a first end and a second end, the first end of the first actuator being movably coupled to the frame structure and the second end of the first actuator being movably coupled to a mounting structure of the work machine;
wherein the second actuator defines a third end and a fourth end, the third end of the second actuator being movably coupled to the frame structure and the fourth end of the second actuator being movably coupled to the mounting structure;
wherein the second pitch angle is opposite in direction to the first pitch angle;
and
wherein, based on a tilting of the operator cabin relative to the frame structure, a plane defined by the operator cabin is substantially parallel to the non-inclined surface.
