Abstract
A broom assembly for a vehicle includes a frame, a broom core axle rotatably coupled to the frame and defining an axis around which a broom rotates, an actuator coupled to the frame and positioned to raise and lower the axle relative to the frame, and a controller. The controller has an output for adjusting the actuator and an input for receiving information from a sensor. To account for the estimated wear, the controller is configured to use the received information to automatically lower the axle over a period of operation and use the sensor input to controllably adjust the actuator to a position setpoint changing over the period of operation. After operation, the controller is configured to use the sensor input to determine a current position, add an offset to the current position to achieve a new sensor target setpoint, and use the new setpoint to adjust the output.
