1. An apparatus for damping a pitching oscillation of a working vehicle comprising:
a first actuator for adjusting a position of an implement coupled to the working vehicle;
a second actuator for adjusting a propulsion rate of the working vehicle; and
a controller in communication with the first and second actuators, the controller configured to:
receive an operating mode signal corresponding to an operating mode of at least one of the working vehicle and the implement, wherein the operating mode includes at least one of a field mode and a transport mode, wherein the field mode corresponds to the working vehicle performing work in a field with the implement in a work position and the transport mode corresponds to the working vehicle traveling with the implement in a raised position;
generate control signals to the first actuator and the second actuator for damping the pitching oscillation, wherein the control signals are generated based on the operating mode of the working vehicle to dampen the pitching oscillation by at least one of adjusting the position of the implement or adjusting the propulsion rate of the working vehicle; and
reallocate damping work between the first actuator and the second actuator by adjusting the control signals in order to dampen the pitching oscillation, wherein the control signals are adjusted based on the operating mode of the working vehicle, a limit value, and a weighting value, the limit value to correspond to at least one of a maximum value and a minimum value of the position of the implement and the propulsion rate of the working vehicle, the weighting value to correspond to activation of the first actuator and the second actuator.
