Abstract: A method is provided that can include activating at least two wireless communication channels in parallel, between a first wireless transceiver and a second wireless transceiver. Each of the at least two wireless communication channels can operate at a different radio carrier frequency, and the first wireless transceiver may be part of a first vehicle. The method can also include transmitting, by the first wireless transceiver, common information in parallel on the at least two wireless communication channels to the second wireless transceiver and deactivating the at least two wireless communication channels.

Abstract: A computer-implemented method is provided that includes obtaining a first secret and a first public key, and obtaining a second secret a second public key. The method may also include authenticating the first public key of the first vehicle based on a first private key associated with the first vehicle, and authenticating the second public key of the second vehicle based on a second private key associated with the second vehicle. The method may also include preventing a man-in-the-middle attack, by securing at least one of a first vehicle-to-central office communication, a central office-to-first vehicle communication, or a first vehicle-to-second vehicle, wherein the first vehicle-to-central office communication and the central office-to-first vehicle communication are authenticated based on a determined private key associated with a respective first vehicle on-board computer, and sending a message, with the central office server, to a vehicle associated with a conditional movement authority.

Abstract: A vehicle control system and method include processors that determine that an energy storage device of a vehicle will have insufficient energy to power a propulsion system of the vehicle under a first set of operational settings to move the vehicle from a first location within a powered segment to a designated second location that is outside of an unpowered segment of a route. Responsive to determining that the energy storage device will have insufficient energy, the processors change one or more settings of the vehicle to operate the vehicle under a second set of operational settings while the vehicle moves within the powered segment of the route to charge the energy storage device to a greater extent relative to operating of the vehicle according to the first set of operational settings.

Abstract: A vehicle control system and method include one or more processors that determine that a vehicle has or will have insufficient energy to power a propulsion system of the vehicle under a first set of operational settings to move the vehicle from a first location to a designated second location that is outside of an unpowered segment of a route along which the vehicle moves. Responsive to determining that the vehicle has or will have insufficient energy, the one or more processors change one or more of a throttle setting or a brake setting of the vehicle to operate the vehicle under a second set of operational settings while the vehicle moves within a powered segment of the route.

Abstract: A system and a method may include one or more sensors disposed onboard a vehicle that may sense one or more characteristics of the vehicle. The system may include one or more processors configured to determining an identification of a switch on a route along which a vehicle moves using one or more sensors onboard the vehicle. A location of the switch is identified with the one or more sensors. A state of the switch is determined with the one or more sensors. The identification of the switch, location of the switch, and the state of the switch are communicated with an off-board database.
