Abstract
A work vehicle having a joint, a joint sensor, a lubricant reservoir, a pump, and a controller. The joint has a first member connected to a second member by a bearing. The joint sensor is configured to provide a joint signal indicative of at least one of a position, velocity, and acceleration of the joint. The pump is configured to dispense lubricant from the lubricant reservoir to the bearing when actuated. The controller receives the joint signal, determines a cumulative bearing travel based on the joint signal, determines a bearing lubrication value based on the cumulative bearing travel, and actuates the pump based on the bearing lubrication value.
