摘要： 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.

摘要： 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.

摘要： A vehicle control system and method wirelessly communicate from at least one wireless transmitter positioned proximate a route crossing to a wireless receiver of a vehicle via a wireless wayside transceiver. The system and method communicate an indication of whether the route crossing is clear for passage of the vehicle through the route crossing. The system and method receive the indication by the wireless transmitter and using the vehicle receiver. A vehicle controller or an operator of the vehicle can determine whether it is safe for the vehicle to travel through the route crossing based on the indication received by the vehicle receiver from the portable transmitter. The vehicle can then be operated based on the determination.

摘要： 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.

摘要： 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.

摘要： A system and method for determining the location of a vehicle when GNSS signals are not available use triangulation between one or two radio transmitters and, respectively, two or one radio receivers mounted on the vehicle. The distance between each radio transmitter and/or each radio receiver can be determined according a phase difference between received radio signals. The radio signals can have the geographical location of the radio transmitter included therein. Utilizing the demodulated geographical location of each radio transmitter and the distance between the radio transmitter and each radio receiver, triangulation can be used to determine the geographical location of the vehicle.

摘要： A controller may be configured to receive one or more measured rotational speeds of a wheel of a vehicle. The controller may be configured to determine whether the one or more measured rotational speeds are unreliable relative to one or more previous rotational speeds of the wheel of the vehicle. The controller may be configured to calculate a replacement rotational speed of the wheel and use the replacement rotational speed of the wheel to control or restrict movement of the vehicle using or based on the replacement rotational speed in place of the one or more measured rotational speeds.

摘要： 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.

摘要： A diagnostic system and method obtain a thermal signature for one or more first components of a powered system. The thermal signature represents thermal measurements obtained at different locations of the powered system. The system and method identify an abnormal operating condition of the one or more first components of the powered system or one or more second components of the powered system based on the thermal signature.
