A gateway device, a communication method and to a communication system for a vehicle, in particular a rail vehicle improve the transmission of data between a first network of the vehicle and a second network of the vehicle. The gateway device is configured to control the transmission of data between the first network of the vehicle and the second network of the vehicle in accordance with the state of the vehicle.

Systems and method for a vehicle network

A system is provided having a vehicle. The vehicle includes a chassis, and a first network bus extending from internally in the chassis to a first network port attached externally to the chassis at a first side of the vehicle. The vehicle includes a second network bus extending from internally in the chassis to a second network port attached externally to the first chassis at a second side of the vehicle. The first network bus has a first electrical configuration and the second network bus has a second electrical configuration that is different than the first electrical configuration.

Transmission system and transmission method

A transmission system includes: a hub to receive a control command from two or more controllers that control operation of an in-vehicle machinery installed in a train, and to control an output of the control command on the basis of a priority assigned to the control command, and a system-controller to determine an operating state of a controller that is a source of the control command, the system-controller being capable of changing a priority assigned to a control command transmitted from a controller whose operating state has been determined, on the basis of a determination result.

Method and system for dynamic selection of communication paths for a moving vehicle
10506395 · 2019-12-10 · ·

A method for wireless communication between a moving vehicle and remote servers through at least one external mobile network. A router in the moving vehicle is configured for receiving and transmitting wireless data to and from both an aggregation server, using aggregated communication over at least two separate links, and at least one other stationary communication server, using non-aggregated communication over a single link. The router is further accessible by a plurality of client devices onboard the moving vehicle. At least one selection rule is provided in the router for selecting whether to use aggregated or non-aggregated communication, and a determination is made, upon a request from a client device to communicate with one of said remote servers, whether one of the at least one rules applies; and if so selecting to use aggregated communication via the at least one other communication server for communication based on the determination.

Vehicle communication systems and control systems

A vehicle control system includes a controller that communicates between a first vehicle and a second vehicle and/or a monitoring device in a vehicle system. The controller determines a communication loss and, responsive to determining the communication loss, switches to communicating via a different communication path. The controller also determines an operational restriction on movement of the vehicle system based on the communication loss that is determined, obtains a transitional plan that designates operational settings of the vehicle system at one or more different locations along a route being traveled by the vehicle system, different distances along the route being traveled by the vehicle system, and/or different times. The controller automatically changes the movement of the vehicle system according to the operational settings designated by the transitional plan to reduce the movement of the vehicle system to or below the operational restriction.

In-train transmission control system and relay device

An object is to provide an in-train transmission control system which can minimize delay in transmission of command data to devices further than the conventional art, in which a central unit provided in any car of a train formation composed of one or more cars and controlling operation of the entire train formation transmits command data to devices provided in some or all of the cars and in which the devices transmit device data to the central unit. The control system comprises relay device provided in the car, and line concentrator allowing the command data to pass therethrough, and when receiving device data from the devices, transmitting the device data to the relay device. The relay device aggregates the device data received from the line concentrator to transmit the aggregated data to the central unit.

Electronic control unit protection framework using security zones
10462155 · 2019-10-29 · ·

Systems are provided herein for a hardware protection framework. A security module monitors a plurality of voltage lines of at least one electronic control unit (ECU) electrically coupled to a communications bus. A voltage differential across at least two of the plurality of voltage lines of the at least one ECU is measured. The voltage differential is compared to a plurality of predetermined signal fingerprints associated with the at least one ECU. A variance in the compared voltage differential is identified relative to one or more of the plurality of predetermined signal fingerprints. Data characterizing the identified variance is provided. In some aspects, a pulse or a data stream is injected based on the voltage differential having an amplitude lower than a predetermined voltage threshold.
