Abstract: An article transport vehicle that travels along a traveling path is provided with an obstacle sensor that detects an obstacle that exists in a detection area, and a control unit that controls the traveling speed of the article transport vehicle based on detection information of the obstacle sensor. A non-detection area where detection of the obstacle by the obstacle sensor is not performed is set within the detectable area of the obstacle sensor, and a situation in which the non-detection area exists on a detection line that joins a part of the detection area and the obstacle sensor is defined as a specific situation. The control unit, in the specific situation, and a situation where an undetectable area in which it is not possible to detect the obstacle exists in the detection area because a shield exists in the non-detection area, reduces the speed of the article transport vehicle to a second traveling speed slower than the first traveling speed.

Abstract: A transport vehicle includes a body including a first wheel and a second wheel, a first drive device that drives the first wheel, a second drive device that drives the second wheel, and a control device, the control device controlling the first drive device and the second drive device in such a manner that a torque ratio of a wheel with increased load, which is a ratio of a torque transmitted to the wheel with increased load to a sum of a first wheel torque and a second wheel torque, is higher while the body is accelerating and decelerating than while the body is traveling at constant velocity, where the wheel with increased load is one of the first wheel and the second wheel that is subjected to an increase in vertical downward load that increases in response to acceleration or deceleration of the body.

Abstract: A job aid system and method determine conditions in which a vehicle system is operating or will operate during movement of the vehicle system along one or more routes. A context-sensitive action checklist is selected or generated based on one or more of the conditions. Input from the operator of the vehicle system is received in response to one or more action items in the context-sensitive action checklist that is presented to the operator. An alertness level of the operator is determined based on the input that is received from the operator. One or more alerting actions can be implemented to increase the alertness level of the operator.

Abstract: A vehicle control system includes a controller configured to control communication between or among plural vehicle devices that control movement of a single vehicle system or a multi-vehicle system via a network that communicatively couples the vehicle devices. The controller also is configured to control the communication using a data distribution service (DDS) and with the network operating as a time sensitive network (TSN). The controller is configured to direct a first set of the vehicle devices to communicate using time sensitive communications, a different, second set of the vehicle devices to communicate using best effort communications, and a different, third set of the vehicle devices to communicate using rate constrained communications.

Abstract: In one example, a wayside device monitoring system is provided. The system may include a wayside device and a controller. The wayside device may detect one or more operating parameters of a vehicle in a vehicle system moving over a route segment. The controller can receive information from the wayside device regarding at least the one or more operating parameters detected, and can control movement the vehicle directly or indirectly based at least in part on the received information.

Abstract: A control system and method identify a first vehicle system that is traveling from a first location toward a different, second location, and a second vehicle system for combining with the first vehicle system into a convoy of vehicle systems. The system and method also direct the first and second vehicle systems to couple with each other for travel as the convoy. The system and method direct one or more of the second vehicle system of the convoy to separate from the convoy and/or a third vehicle system that is outside of the convoy to join the convoy by coupling with one or more of the first vehicle system or the second vehicle system in the convoy in at least one intermediate location between the first location and the second location.

Abstract: A system that can automatically control the emissions of each locomotive in a consist to reduce overall train emissions. An emissions module determines the amount of emissions emitted by a train. An emissions control module commands the locomotive, via the train control system, to operate in a predetermined state to achieve a particular amount of emissions. A location module can track the location of the locomotive of the train relative geographic locations having emission regulations so that the emissions control module can command appropriate changes in the locomotive to reduce emissions.
