A system for modifying an operational condition, i.e., the discharge speed or position, of a material-handling vehicle (MHV). The system includes a computer utilizing a machine learning engine to analyze visual data, a vision system comprising at least one camera mounted to the MHV for generating said visual data, and a controller operatively connected to the MHV. The vision system generates visual data by imaging an observed area proximate the MHV. That data is transmitted to the computer which, using a processor, analyzes the data to determine if a current operational condition of the MHV is outside of a tolerance band. If it is outside of the band, the computer system generates operational commands to bring the MHV back within the tolerance band and transmits said commands to the controller.

An automotive construction machine, in particular a slipform paver or a road milling machine, has at least one front running gear and one rear running gear in the working direction. As the construction machine advances, the lifting systems of the front running gear are extended or retracted such that the machine frame remains in a predetermined orientation to the surface of the ground in the longitudinal direction. Irregularities in the ground surface are detected as the construction machine advances, and the position of the front lifting systems, predetermined by the control or regulating unit, is monitored to keep the machine frame in a predetermined orientation to the ground surface. As the construction machine advances, the control of the rear lifting systems is engaged with a time delay subject to the control of the front lifting systems. Consequently, the working system of the construction machine, in particular the concrete mold or milling drum, is adjusted to the correct height with respect to the ground surface, so that the working system does not copy the course of the ground.

The invention relates to an automotive construction machine, in particular a road milling machine, recycler or surface miner, and to a method for displaying an image of the surroundings of an automotive construction machine. The construction machine according to the invention has an image display device for displaying a bird's eye view image of the surroundings of the construction machine, which image display device has a camera system with a plurality of cameras provided on the machine frame for recording individual overlapping image regions of the construction machine surroundings from different image recording positions, and an image processing system. The image processing system is configured in such a way that image details of the individual image regions are joined together to form a total image from a bird's eye view. For this purpose, the construction machine has a position detection device, which detects the height and/or the incline of the machine frame in relation to the ground surface and cooperates with the position detection device in such a way that when the image details of the individual image regions are joined together to form a total image from a bird's eye view, the course of the stitching which is located between the image details and within the overlapping regions of the image regions is determined depending on the height and/or the incline of the machine frame in relation to the ground surface.

A monitoring system for a paving machine having a conveyor system is disclosed. The monitoring system may include an input device configured to receive a first input indicative of a paving material efficiency factor, and a first sensor configured to generate a first signal indicative of a conveyor speed. The monitoring system may further include a controller electronically connected to the input device and the first and configured to determine an amount of material deposited by the paving machine based on the paving material efficiency factor and the conveyor speed.

A system and method for limiting a turning speed of a compactor is disclosed. The compactor includes a steering member configured to receive operator steering input. The system may comprise a speed sensor, and a controller in communication with the speed sensor. The speed sensor may be mounted on the compactor and configured to measure a travel speed of the compactor over a surface. In some embodiments, a temperature sensor, configured to measure a temperature of the surface, may be mounted on the compactor and in communication with the controller. The controller is configured to receive the travel speed and/or temperature, and to limit a turning speed of the compactor when a condition is satisfied.

A water ballast for a compactor is disclosed. A ballast tank is installed under a cover plate having a plurality of holes. Through the holes of the cover plate, water falling onto the cover plate drains into the ballast tank. The edges all around the cover plate are slightly angled upwards in order to prevent water from draining out of the cover plate. Also, the water ballast has a ballast drain port on the compactor's frame. The ballast drain port is connected with a drain hole on the ballast tank by a drain hose so that it is used to drain out some water from the ballast tank.

A road paver includes a screed for applying a material layer to a foundation and a layer thickness detecting device for detecting the thickness of the applied material layer. The layer thickness detecting device includes a first sensor for detecting a first distance from the applied material layer and a second sensor for detecting a second distance from the foundation. The layer thickness detecting device is securely attached to the screed.

A paving machine for reducing transition marks in a mat. The paving machine may comprise a frame, a tow arm, a screed assembly, a sensor and a controller. The screed assembly includes a main screed plate and an extension plate. The main screed plate is configured to pave a first surface section of the mat. The extension plate includes an extension trailing edge having an inner end. The extension plate is configured to pave a second surface section of the mat. The sensor is configured to sense transition marks in the mat proximal to an intersection between the first and second surface sections and to transmit data indicative of such to the controller. The controller may be configured to determine from the data received from the sensor when the inner end is disposed above or below the first plane, and move the inner end to the first plane.

A cold planer includes a conveyor system having a conveyor belt, a frame, and a roller rotatably coupled to the frame, a motor coupled to the conveyor belt and configured to drive the conveyor belt, a tension screw coupled between the roller and the frame, a tension sensor configured to measure the tension on the conveyor belt, and a controller communicably coupled with the tension sensor and the motor. The controller is configured to receive the tension from the tension sensor and calculate, based on the tension from the tension sensor, a mass flow rate of material on the conveyor belt.
