Abstract:
A system includes a locator device and one or more processors operably connected to the locator device. The locator device determines a trailing distance between a trailing vehicle system that travels along a route and a leading vehicle system that travels along the route ahead of the trailing vehicle system in a same direction of travel. The one or more processors compare the trailing distance to a first proximity distance relative to the leading vehicle system. In response to the trailing distance being less than the first proximity distance, the one or more processors set a permitted power output limit for the trailing vehicle system to be less than a maximum achievable power output for the trailing vehicle system, the permitted power output limit being set based on a power-to-weight ratio of the leading vehicle system.
Abstract:
A system includes a locator device, a communication circuit, and one or more processors, all disposed onboard a trailing vehicle system that travels along a route behind a leading vehicle system. The locator device determines a location of the trailing vehicle system. The communication circuit periodically receives a location of the leading vehicle system in a message. The processors monitor a trailing distance between the trailing vehicle system and the leading vehicle system based on the respective locations of the leading and trailing vehicle systems. Responsive to the trailing distance being less than a first proximity distance relative to the leading vehicle system, the processors set an upper permitted power output limit for the trailing vehicle system that is less than an upper power output limit of the trailing vehicle system to reduce an effective power-to-weight ratio of the trailing vehicle system.

Abstract:
A ride control system for controlling a plurality of vehicles on a path includes a path processor and a bi-directional voting circuit in circuit with the path processor. Each vehicle of the plurality of vehicles may include a vehicle processor supported by the at least one vehicle and shunt relays in circuit with the at least one vehicle processor. Each vehicle processor may be configured to close a respective shunt relay upon a predetermined condition of the vehicle whereby the bi-directional voting circuit is activated to notify all other vehicles.
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 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 method and system are provided to obtain, with one or more processors, a speed profile of a vehicle system for a designated route traveled by the vehicle system. The designated route includes a plurality of segments, and the speed profile includes a planned segment speed for each segment. One or more planned segment speeds are identified that correspond to a point of interest, and respective priorities are assigned to the identified segment speeds based on the point of interest forming prioritized segment speeds. First discrete numeral values are displayed on a display, representing the planned segment speeds of the prioritized segments that are within a predetermined distance forward of a motion of the vehicle system. Second discrete numeral values are displayed on the display, corresponding to remaining segment speeds that are within the predetermined distance, until a predetermined threshold of discrete numeral values is reached.
