Claim 0:
1. A system for automatic tilting of an operator cabin of a work machine, the work machine including a frame structure, the system comprising:
at least one first sensor coupled to the work machine, wherein the at least one first sensor is configured to generate a first signal indicative of a first pitch angle of the work machine relative to a non-inclined surface;
a lower structure rotatably coupled to the frame structure, the lower structure supporting the frame structure;
a tilting mechanism adapted to tilt the operator cabin relative to the frame structure, the tilting mechanism including:
a mounting structure fixedly coupled with the operator cabin;
a first actuator defining a first end and a second end, wherein the first end of the first actuator is movably coupled to the frame structure and the second end of the first actuator is movably coupled to the mounting structure; and
a second actuator defining a third end and a fourth end, wherein the third end of the second actuator is movably coupled to the frame structure and the fourth end of the second actuator is movably coupled to the mounting structure; and
a controller communicably coupled to the at least one first sensor, the first actuator, and the second actuator, wherein the controller is configured to:
receive the first signal indicative of the first pitch angle of the work machine;
determine a second pitch angle based on the first pitch angle; and
control at least one of the first and second actuators to tilt the operator cabin by the second pitch angle relative to the non-inclined surface, wherein the second pitch angle is opposite in direction to the first pitch angle;
determine an uphill movement of the work machine and generate 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; and
determine a downhill movement of the work machine and generate 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; 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.
