A navigation system for a host vehicle is provided. The system may comprise at least one processing device comprising circuitry and a memory. The memory includes instructions that when executed by the circuitry cause the at least one processing device to: receive a plurality of images acquired by a camera, the plurality of images being representative of an environment of the host vehicle; analyze the plurality of images to identify a presence in the environment of the host vehicle a navigation rule suspension condition; temporarily suspend at least one navigational rule in response to identification of the navigation rule suspension condition; and cause at least one navigational change of the host vehicle unconstrained by the temporarily suspended at least one navigational rule.

A working machine includes a body, a ground-engaging propulsion structure supporting the body, a drive arrangement configured to provide motive power to the ground engaging propulsion structure, a braking system actuatable to apply a braking force to the ground engaging propulsion structure, a control system, and a sensor assembly configured to determine an output of the drive arrangement and to provide an output to the control system. The control system is configured to apply a first braking force to the ground engaging propulsion structure that is based on the determined output of the drive arrangement.

Systems and methods of operating a vehicle subject to a travel restriction determine when the vehicle is traveling in an unloaded state; determine a speed of the vehicle when the vehicle is traveling in the unloaded state to produce an actual travel empty speed; compare the actual travel empty speed with an historical travel empty speed for the vehicle; and determine that the vehicle operation is subject to the travel restriction when the actual travel empty speed is less than a predetermined percentile of the historical travel empty speed. When the vehicle operation is not subject to the travel restriction, the systems and methods further evaluate vehicle operation based on an established performance parameter for the vehicle under a normal operating condition; and change a vehicle performance parameter during future vehicle operation based on the evaluation.

A method for shifting a transmission in a machine. The method includes detecting a request for a directional shift of the transmission and determining a ground speed of the machine in response to the request. The method further includes overriding the request if the ground speed is above a ground speed threshold. Further, the method includes preparing the machine for the directional shift by limiting an output speed of a power source of the machine and by issuing a command to a brake unit of the machine to reduce the ground speed of the machine. Furthermore, the method includes validating and raising the request to the transmission to execute the directional shift if the ground speed is below the ground speed threshold.

The present disclosure relates to a method of controlling gear selection in a transmission of a vehicle in response to a directional shift requested by an operator and to a control system for controlling gear selection to manage directional shifts in vehicles, from a first direct to a second direction (e.g. forward to reverse). The method compares the current transmission output speed with a predetermined direction shift threshold transmission output speed. If the current transmission output speed is less than or equal to the predetermined direction shift threshold transmission output speed, the transmission is caused to execute a direction shift from the initial first direction gear to the same second direction gear, or a next highest second direction gear if there is no second direction gear which corresponds to the initial first direction gear. If the current transmission output speed is greater than the predetermined direction shift threshold transmission output speed, the direction shift is inhibited until the current transmission output speed slows to less than or equal to the predetermined direction shift threshold transmission output speed.

A work machine includes an engine for driving a primary working unit. At least one hydraulically powered auxiliary working unit is powered by a hydraulic pump. The engine and an electric motor both provide power to the hydraulic pump via a planetary gear set which sums the power inputs from the engine and the electric motor. The pump speed of the hydraulic pump is thereby decoupled from the engine speed of the engine.

An automatic torque control system and methods for automatically controlling a torque of a vehicle are disclosed. The method includes detecting when the vehicle engages a load. The method further includes automatically decreasing the torque when the vehicle engages the load and prior to one or more wheels of the vehicle slipping.

A navigation system for a host vehicle may include a processing device including circuitry and a memory storing instructions that when executed by the circuitry cause the at least one processing device to receive images acquired by a camera representative of an environment of the host vehicle, and analyze the images to identify a double merge scenario including a first flow of traffic and a second flows of traffic in a same direction that merge to form a merged flow of traffic in a merged lane. The instructions that when executed by the circuitry may further cause the processing device to cause a navigational change in the host vehicle based on a trajectory of a first target vehicle in the first flow of traffic and a trajectory of a second target vehicle in the second flow of traffic.

The present disclosure relates techniques for autonomously controlling heavy equipment and vehicles using task hierarchies. Particularly, aspects of the present disclosure are directed to obtaining a task to be performed by an autonomous vehicle, determining subtasks to be performed to perform the task, obtaining sensor data providing a representation of operation of the autonomous vehicle in a worksite environment and situational context of the worksite environment, determining a task context for a subtask based on the sensor data, identifying a predictive model from a library of predictive models based on the task context, estimating, by the predictive model, a set of output data based on sensor data, and controlling operations of the autonomous vehicle in the worksite environment to perform the subtask using a set of input data derived from the sensor data and the set of output data.

The invention involves a low speed control system and method for automatically regulating the speed of work vehicles or equipment and, more particularly, vehicles that apply, remove or modify roadways or road markings. The system includes a controller, a speed display, at least one rotary encoder or the like, and one or more Eddy current or mechanical brakes for inhibiting motion of the vehicle at the operator's control. The brakes may be pneumatic, spring operated, Eddy current, or hydraulic that are controlled in response to feedback from the at least one rotary encoder for compliance with the preset speed on the speed display. In another embodiment, a throttle control is also provided.
