A method and a system for avoiding collision of an object with a work tool coupled to a work machine. The method comprising generating an object signal by an object detector, monitoring the object signal in real-time by a processor, processing the object signal to detect an object at least partially buried in the ground surface, determining a distance between the object and a distance threshold, and sending by a controller a control signal to one or more of a machine control system and a work tool control system to modify one or more of a movement of the work tool or the work machine based on the object reaching the distance threshold.

A method of controlling a mobile machine having a set of ground engaging elements includes receiving an image of terrain proximate the mobile machine, detecting a contour of the terrain, determining a projected path of the set of ground engaging elements based on the detected contour of the terrain, and controlling a display device to display the image with an overlay representing the projected path of the ground engaging elements.

A method for assisting an operator in operating a machine. The method includes receiving, by a controller, a selection of a task of a plurality of tasks, each task associated with a corresponding movement pattern of the machine; sensing, by a sensor unit, at least one condition of at least one component of the machine associated with the selected task; and determining, by the controller, whether the condition is within a predetermined set of parameters associated with the selected task. In response to determining that the condition is not within the predetermined set of parameters, the method further includes generating, by the controller, an audible or a haptic signal associated with at least one of the condition or the at least one component.

A work machine includes an engine, a travel drive system, a work implement, an apparatus drive system with a hydraulic pump, an accelerator operating member, a work implement operating member, and a controller. The controller controls the apparatus drive system in accordance with an operating amount of the work implement operating member. The controller determines a target tractive force of the travel drive system based on an operating amount of the accelerator operating member. The controller determines an allowable acceleration of the work machine. The controller determines an upper limit of tractive force of the travel drive system based on the allowable acceleration. The controller corrects the target tractive force so as to be equal to or less than the upper limit when the target tractive force is greater than the upper limit. The controller controls the travel drive system based on the corrected target tractive force.

An example calibration system may include a tractor and a calibration unit. The tractor may include a first sensor and a second sensor. The calibration unit may include a processing unit and a non-transitory computer-readable medium containing instructions to direct the processing unit to: (1) determine a first estimate for a tractor parameter based upon signals received from the first sensor; (2) determine a second estimate for the tractor parameter based upon signals received from the second sensor; (3) determine a third estimate for the tractor parameter based upon a combination of the first estimate and the second estimate; (4) determine a tractor parameter correction based upon the second estimate and the third estimate; and (4) apply the tractor parameter correction to the second sensor to control positioning of the tractor.

To provide a technique for reliably acquiring a required braking power during travel and for efficiently using a regenerative power generated during braking. A work vehicle calculates a regenerative power outputted from an electric motor and a target hydraulic driving power for driving a hydraulic pump, supplies the regenerative power to the generator motor operating as a motor and makes the generator motor consume the regenerative power in a case where the regenerative power is equal to or smaller than the target hydraulic driving power, and supplies the regenerative power to the generator motor operating as the motor and makes an exhaust brake consume a power equivalent to a difference between the regenerative power and the target hydraulic driving power in a case where the regenerative power is larger than the target hydraulic driving power.

A method for control of a compacting machine including a ground-engaging implement and a compacting drum includes receiving a request to activate the compacting machine, receiving a command to propel the compacting machine, and automatically generating a command to move the implement to a raised position in which the implement does not engage the ground based on: the request to activate the compacting machine, the command to propel the compacting machine, or a determination that the implement is below a threshold height. The method also includes, once the implement is in the raised position, propelling the compacting machine.

Provided is a conveying vehicle that ensures efficiently travelling while suppressing vehicle slip. A dump truck 100 includes a vehicle body 101 provided with wheels 103 and a vehicle control device 300 and travels on a travel route. The vehicle control device 300 calculates and stores slip limit values at a plurality of positions on the travel route, reads out the slip limit values to calculate at least one of a maximum acceleration and a maximum deceleration of the dump truck 100 at which the wheels 103 is capable of maintaining a grip state against a road surface, and sets a target travel speed at a travel position between the dump truck 100 and a target position according to a target speed at the target position and at least one of the maximum acceleration and the maximum deceleration.

The invention relates to a method for a control unit (10) for stopping a vehicle (1) when stopping at different types of stop positions (2, 3, 4), the method comprising the following steps: —(S1) the control unit receiving input about a specific stop position for the vehicle, associated with when the vehicle is about to stop during a stopping sequence, the input being indicative of whether the specific stop position requires a high-precision stop or if a stop with a lower precision can be used; and —(S2) when the stop position requires a high-precision stop, the control unit controlling the stopping sequence such that the vehicle stops with a first stopping precision level with respect to the specific stop position, and when a lower precision can be used for the stop, the control unit controlling the stopping sequence such that the vehicle stops with a second stopping precision level which is lower than the first precision level. The invention further relates to a control unit and to a vehicle comprising the control unit.

A heavy-duty vehicle includes a chassis, a wheel supporting the chassis, a drive system, a service brake, a drive system controller, and a service brake controller. The drive system includes a motor associated with the wheel. The motor is configured to propel the wheel and to apply a dynamic brake torque to the wheel. The service brake is associated with the wheel and configured to apply a service brake torque to the wheel. The drive system controller controls operation of the motor. The drive system controller selectively modulates the dynamic brake torque to the wheel based on traction conditions. The service brake controller controls operation of the service brake. The service brake controller may selectively modulate the service brake torque to the wheel based on the traction conditions. Modulation of the dynamic brake torque may be disabled during modulation of the service brake torque.
