A work vehicle (10) includes a frame assembly (14) and an attachment assembly (16). The attachment assembly (16) has an attachment end (26) which is pivotally connected to the frame assembly (14) and a distal end (27) which is configured for receiving a variable load (L). One or more force sensors (34) sense a plurality of forces associated with the attachment end (26), with each force sensor (34) providing an output signal representing at least one sensed force. An inclination sensor (36) senses an inclination associated with the frame assembly (14) relative to a horizontal reference. The inclination sensor (36) provides an output signal representing the sensed inclination. An electrical processing circuit (40) is coupled with each force sensor (34), the inclination sensor (36) and a controllable output (38). The electrical processing circuit (40) is configured for receiving the output signal from each force sensor (34), determining a value of a couple at the frame assembly (14) which is associated with the sensed forces, comparing the couple with a threshold value which is dependent on the sensed inclination, and controlling the controllable output (38) dependent on the comparison. |
