A controller is configured to determine a target excavation depth of a first pass based on a position of an excavation end, a target soil amount, and an excavation distance. The controller is configured to move a work implement to the target excavation depth of the first pass to execute an excavation of the first pass. The controller is configured to acquire an actual soil amount excavated in the first pass. The controller is configured to modify the target soil amount based on the actual soil amount. The controller is configured to determine the target excavation depth of a second pass based on the modified target soil amount. The controller is configured to move the work implement to the target excavation depth of the second pass to execute the excavation of the second pass.

A work machine includes a frame, a traction system supporting the frame, a power source mounted on the frame, a switched reluctance motor, an inverter configured to control power to the motor from a power source, and a controller. The controller is configured to receive a signal indicating a desired torque and determine if the desired torque is between an upper threshold and a lower threshold. If the desired torque is between the upper threshold and the lower threshold, pulse width modulation is used to produce a PWM adjusted torque command, and the motor is commanded based on the PWM adjusted torque command. The PWM adjusted torque command is configured to cycle between the upper threshold and the lower threshold to produce the desired torque.

Systems and methods for adjusting a height of an implement mounted on a body of a vehicle as the vehicle travels over a terrain are provided. Sensor data is received from a set of sensors disposed on the vehicle. A trajectory associated with the vehicle is determined based on the received sensor data. A profile of the terrain is estimated based on the determined trajectory associated with the vehicle. A ditch is detected in the terrain and compensation values for adjusting the height of the implement are determined based on the estimated profile of the terrain to compensate for the detected ditch. One or more control signals are transmitted to one or more actuators for adjusting the height of the implement based on the determined compensation values.

Techniques for position-based cross slope control of a construction machine are disclosed. A site design that includes a set of target cross slopes for a construction site is obtained, with each of the set of target cross slopes associated with a 2D location within the construction site. Sensor data is captured using at least one sensor mounted to the construction machine. A geospatial position and a direction of travel of the construction machine are determined based on the sensor data. A target cross slope for the construction machine is generated by querying the site design using the geospatial position and the direction of travel.

One or more processors control a first work machine to work according to a first work lane. The one or more processors control a second work machine to work according to a second work lane. The one or more processors determine whether at least a part of the second work machine is located in a first work area. When at least a part of the second work machine is located in the first work area, the one or more processors control the first work machine to perform an interference avoidance operation with respect to the second work machine.

A work machine that has a blade that is positionable at a plurality of angles relative to the work machine, a positioning system coupled to the blade to transition the blade to any one of the plurality of angles, a user interface providing a user input, and a controller in communication with the positioning system and the user input. Wherein, when the controller receives a first user input signal from the user interface, the controller positions the blade in a first preset position with the positioning system.

An autonomous earth moving system can select an action for an earth moving vehicle (EMV) to autonomously perform using a tool (such as an excavator bucket). The system then generates a set of candidate tool paths, each illustrating a potential path for the tool to trace as the earth moving vehicle performs the action. In some cases, the system uses an online learning model iteratively trained to determine which candidate tool path best satisfies one or more metrics measuring the success of the action. The earth moving vehicle the executes the earth moving action using the selected tool path and measures the results of the action. In some implementations, the autonomous earth moving system updates the machine learning model based on the result of the executed action.

Systems and devices for use in executing a tree felling operation are disclosed. A tree felling blade for use in connection with a tree felling operation includes a leading cutter comprising a leading cutter point and a leading transverse cutting blade. The tree felling blade includes a trailing cutter comprising a trailing cutter point and a trailing transverse cutting blade. The tree felling blade comprises a roller portion comprising a concave curvature, wherein the roller portion is connected to the leading cutter and the trailing cutter.

A bulldozer includes: a travel manipulation lever that receives a manipulation of an operator and outputs a travel command to allow a travel device to travel or to stop the travel device; a fuel adjustment dial that sets a rotation speed of an engine; a seating sensor that outputs a seating signal indicating a sensed result of whether or not the operator is seated in an operator seat; a monitor that performs notification to the operator; and a controller. When the travel command to allow the travel device to travel is issued from the travel manipulation lever, a set value of the rotation speed of the engine is lower than or equal to a predetermined value, and the operator is not seated in the operator seat, the controller causes the monitor to perform the notification.

Some embodiments of the disclosure are directed to latching interfaces of a vehicle. In some embodiments, the vehicle comprises a latch system including a plurality of latches configured to selectively interlock with a corresponding first plurality of latch receptacles of a respective payload. In some embodiments, the vehicle comprises a second plurality of latch receptacles disposed on exterior portions of the chassis of the vehicle. In some embodiments, the second plurality of latch receptacles correspond to the first plurality of latch receptacles. In some embodiments, a spatial arrangement of the second plurality of latch receptacles on the exterior portions of the chassis of the vehicle corresponds to a spatial arrangement of the first plurality of latch receptacles on exterior portions of the respective payload. In some embodiments, the second plurality of latch receptacles of the vehicle are configured to interlock with a latching interface of an external system.
