Abstract: A system for predicting maintenance of an endless flexible member of a road construction machine. The system includes a sensor and a controller. The sensor detects a distance between a frame portion and a roller portion. The roller portion is movable with respect to the frame portion to tension the endless flexible member, which is configured to convey materials or power in the road construction machine. The controller is communicably coupled to the sensor. The controller is configured to compute a change in the distance over time between the frame portion and the roller portion that is required to maintain proper working tension on the endless flexible member; and generate alerts when a value associated with the change in the distance exceeds one or more predetermined threshold values.

The system includes a two lidar sensors oriented to emit light beams toward a surface proximate the vehicle. The system also includes at least one mirror associated with each lidar sensor configured to reflect light beams emitted away from the surface.

The lidar sensors receive lidar returns, either directly from the surface or reflected off the mirror and may generate sensor data associated with an area proximate the vehicle. A vehicle computing system controls the vehicle based in part on the sensor data.

Abstract: A test system includes a master electronic control module (ECM) configured to receive user input for performing a test action. The master ECM determines one or more subsystem ECMs associated with the requested test action and a sequence of operations to be controlled by the subsystem ECMs to perform the requested test action. The master ECM provides instructions to the subsystem ECMs to perform the operations, along with parameters for those operations. The master ECM may determine whether a test action is appropriate to perform, based on sensor data, before instructing subsystem ECMs to perform the operations of the test action.
