Abstract: A lift vehicle includes a chassis, an implement, a lift arm coupling the implement to the chassis, a load sensor, a tilt sensor, and a controller. The lift arm includes an actuator configured to selectively extend the lift arm and a length sensor configured to provide data relating to a length of the lift arm. The load sensor can provide data relating to a load at the implement. The tilt sensor can provide data relating to an angular orientation of the chassis relative to a reference plane. The controller can receive data from the length sensor, the load sensor, and the tilt sensor. The controller can determine, based on the data from the load sensor and the tilt sensor, an operating envelope for the lift arm. The operating envelope can include a maximum extension of the lift arm. The controller can selectively limit an operation of the lift arm such that the lift arm operates within the operating envelope.
