Abstract: A system for calculating a desired time of arrival to a target destination for a vehicle includes a device mountable to a first vehicle. The device includes a transmitter, a receiver, and a logic unit configured to receive signals for determining a current position and a current vehicle speed of the first vehicle, the logic unit being further configured to determine an estimated time of arrival at a target destination for the first vehicle based on predetermined route information, the current position of the first vehicle and the target destination of the first vehicle. The device is configured to transmit the estimated time of arrival at the target destination for the first vehicle, receive, from a second vehicle, an estimated time of arrival at the target destination for the second vehicle, calculate a desired estimated time of arrival at the target destination for the first vehicle based on the received estimated time of arrival at the target destination for the second vehicle, and calculate a desired vehicle speed for the first vehicle for achieving the desired estimated time of arrival at the target destination for the first vehicle.

Abstract: An excavator calibration framework comprises an excavator, a laser distance meter (LDM), and a laser reflector. The excavator comprises a chassis, linkage assembly (LA), sensor, implement, and control architecture. The LA comprises a boom, stick, and four-bar linkage (4BL) with the sensor on a 4BL dogbone linkage. The control architecture comprises a controller programmed to execute an iterative process at successive implement curl positions. The iterative process comprises generating a measured dogbone angle θDFMeasured, determining a height Ĥ and a distance {circumflex over (D)} between an implement node and the LDM, and determining an implement node position. The iterative process further comprises determining an estimated implement angle θGHEstimated, and generating a mapping equation comprising linkage angle inputs (θDFMeasured, θGHEstimated) and n unsolved 4BL linkage length and angle offset parameters. The controller is programmed to generate and solve a set of m mapping equations comprising the n unsolved parameters.

Abstract: A positioning device for a remote control of a heavy duty vehicle or agricultural vehicle includes an elastic element. The elastic element has a fastening portion, configured to be secured to a body of the remote control, and a retaining portion, arranged to cooperate with an actuator of the remote control at a threshold position delimiting a first portion of a displacement trajectory of the actuator, and a second portion of the displacement trajectory, so as to oppose movement of the actuator according to its displacement trajectory along at least one displacement direction upon switching of said threshold position and allow switching at the threshold position in said displacement direction as a result of application of a threshold switching force exerted on the actuator. The threshold switching force is higher than a displacement force necessary for movement of the actuator on the first or second portion of the displacement trajectory.

Abstract: A system for planning material dumping operations includes one or more machine controllers and a dump zone controller. Each of the one or more machine controllers are configured to provide dump planning information for the one or more machines and configured to determine actual dump information for dumping operations of machines. The dump zone controller is communicatively coupled with each of the one or more machine controllers and configured to initialize a dump zone. The dump zone controller is configured to plan an array of dump locations at the dump zone, each dumping location associated with a dumping operation. The dump zone controller is further configured to update the array of dump locations based on the actual dump information, the updated array of dump locations including, at least, updated dump location instructions, the updated dump locations based, in part, on the array of dump locations and the actual dump information.

Abstract: A control system for operating a machine includes a perception system and a controller. The perception system includes sensors that generate raw data signals pertaining to characteristics of an environment associated with the machine. The perception system also includes a processor that receives the raw data signals from the sensors and determines the characteristics of the environment from the received raw data signals. The determined characteristics of the environment include at least terrain features associated with a job site, and a presence of objects in the vicinity of the machine, wherein the objects include one of: stationary objects and moving objects. The processor also determines a current operating mode of the machine. The controller is communicably coupled to the processor and is configured to actuate subsequent operation of the machine based on the current operating mode of the machine and the characteristics of the environment determined by the processor.
