摘要： A method for machine grade assist includes determining whether user input will cause an implement of a machine to dig below a desired grade. User input to move a stick of an excavator can be blocked and/or delayed using hydraulic pressure so that movement of both the stick and the boom of the excavator can be synchronized to prevent a bucket of the excavator from digging below a desired grade when the stick is moved.

摘要： An automated backslope cutting system which, based on a survey of an area, automatically adjusts a scraper blade during the cutting of a ditch backslope. The automated backslope cutting system generally includes a scraper which is automatically adjusted by a computing device to effectuate cutting of backslopes for a ditch based on a desired cut profile. The desired cut profile may be manually entered by the operator and automatically processed by the computing device. The area is surveyed with a positioning sensor to determine an optimal desired cut profile requiring a minimum number of cuts. A proximity sensor may be provided to accommodate for rotational movement of the cutting blade as the scraper performs cuts. A control software is provided for execution by the computing device to provide functionality including the automatic adjustment of hydraulic actuators controlling movement of the cutting blade as the scraper cuts the ditch and backslopes.

摘要： A speed measurement system for use with a machine having a component rotationally mounted inside a housing may have a first sensing element configured to be mounted to the housing adjacent the component, and a second sensing element configured to be mounted to the housing. The first sensing element may be configured to generate a first signal indicative of a rotational velocity of the component. The second sensing element may be configured to generate a second signal indicative of a rotational rate of the housing. The speed measurement system may also have a controller in communication with the first and second sensing elements. The controller may be configured to determine a rotational speed of the component relative to an offboard reference based on the first and second signals.

摘要： A method for controlling operations of a first machine and a second machine at a worksite is provided. The method includes establishing a communication between the first machine and the second machine. The method further includes communicating a signal indicative of one or more machine parameters between the first machine and the second machine. The method includes communicating a signal indicative of multiple implement parameters between the first machine and the second machine. The method further includes comparing the one or more machine parameters and the multiple implement parameters of at least one of the first machine and the second machine with a predefined value. The method further includes determining one or more outputs based on the comparison. The method further includes controlling the operation of at least one of the first machine and the second machine based on the one or more outputs to minimize an impact.

摘要： A cycle counter for a wheeled tractor scraper is disclosed. The cycle counter may have an ejector configured to push material from a bowl of the wheeled tractor scraper, a sensor configured to generate a pressure signal indicative of a position of the ejector, and a controller in communication with the sensor. The controller may be configured to determine movement of the ejector toward a full dump position based on the pressure signal, and to record completion of a cycle for the wheeled tractor scraper after the ejector has reached the full dump position only if a value of the pressure signal exceeded a threshold value during movement of the ejector toward the full dump position.
