Abstract:
An energy management system and method for a vehicle system operate the vehicle system according to a current trip plan as the vehicle system travels along a route during a trip. The current trip plan designates operational settings of the vehicle system. The system and method also revise the current trip plan into a revised trip plan responsive to current, actual operation of the vehicle system differing from the current trip plan by at least a designated threshold amount. The revised trip plan designates operational settings of the vehicle system and includes an initial designated operational setting that matches the current, actual operation of the vehicle system.
Abstract:
A system and method for determining dynamically changing distributions of vehicles in a vehicle system are disclosed. The system and method determine handling parameters of the vehicle system. The handling parameters are determined for different distributions of the vehicles among different groups at different potential change points along a route. The system and method also determine whether to change the distributions at potential change points based on the handling parameters. Based on determining that the distributions are to change, a selected sequence of changes to the distributions is determined at one or more of the potential change points along the route. Change indices are generated based on the selected sequence. The change indices designate times and/or the one or more potential change points at which the distributions changes. The vehicles included in a common group have common designated operational settings while the vehicles are in the common group.
Abstract:
An alerter augmentation system includes one or more processors that determine an alertness of an operator of a vehicle system. The one or more processors also generate operator input requests that are separated in time by a temporal delay. These input requests seek responses or action by the operator in an attempt to keep or make the operator alert. The one or more processors change one or more of the temporal delay between the input requests and/or a type of the input requests that are generated based at least in part on the alertness of the operator that is determined.

Abstract:
A vehicle control system and method determine one or more designated speeds of a trip plan for a trip of a vehicle system along a route. The trip plan can designate the one or more designated speeds as a function of one or more of time or distance along the route for the trip. Geometry of the route that the vehicle system will travel along during the trip is determined, as well as one or more prospective forces that will be exerted on the vehicle system during movement of the vehicle system along the route for the trip based at least in part on the geometry of the route. The trip plan is revised to reduce at least one of the prospective forces by reducing at least one of the designated speeds of the trip plan based on the one or more prospective forces that are determined.
Abstract:
A vehicle control system includes one or more processors configured to assign plural vehicles to different groups in one or more vehicle systems for travel along one or more routes. The one or more processors also are configured to determine trip plans for the different groups. The trip plans designate different operational settings of the vehicles in the different groups at different locations along one or more routes during movement of the one or more vehicle systems along the one or more routes. The one or more processors also are configured to modify one or more of the groups to which the vehicles are assigned or the operational settings for the vehicles in one or more of the vehicle systems based on a movement parameter of one or more of the vehicle systems. The trip plans for the different groups of the vehicles are interdependent upon each other.
Abstract:
A control system includes an energy management system and an isolation control system. The energy management system generates a trip plan that designates operational settings of a vehicle system having powered units that generate tractive effort to propel the vehicle system. The energy management system determines a tractive effort capability of the vehicle system and a demanded tractive effort of a trip. The energy management system identifies a tractive effort difference between the tractive effort capability of the vehicle system and the demanded tractive effort of the trip and selects at least one of the powered units based on the tractive effort difference. The isolation module remotely turns the selected powered unit to an OFF mode such that the vehicle system is propelled along the route during the trip by the powered units other than the selected powered unit.
Abstract:
An apparatus includes a first element for identifying planned applications of tractive effort and braking effort for a railway vehicle while traversing a track segment. The apparatus includes a second element for determining a slack condition of the railway vehicle at one or more locations on the track segment in advance of the railway vehicle traversing the track segment based on the planned applications of tractive effort and braking effort. The apparatus includes a third element for redetermining the slack condition at the one or more locations based on at least one deviation from the planned applications of tractive effort and braking effort.
