摘要： A vehicle control system receives a proximity signal at a sensor assembly from a vehicle system. The proximity signal indicates that the vehicle system is approaching a location of the sensor assembly. A sensor of the sensor assembly is activated responsive to receiving the proximity signal. One or more characteristics of the vehicle system are sensed as the vehicle system moves by the sensor assembly. A sensor signal that represents the one or more characteristics of the vehicle system is communicated to an onboard controller of the vehicle system and/or an off-board system to control operation of the vehicle system based on the one or more characteristics of the vehicle system.

摘要： A system and a method include an onboard communication system configured to be disposed onboard a vehicle system and comprising one or more processors. The one or more processors may generate a session key that includes a shared secret key that is known by the onboard communication system and an off-board communication system, generate one or more encryption keys by hashing the session key with an identifier based on a cycle time that is known by the onboard communication system and the off-board communication system, generate one or more encrypted messages by encrypting one or more messages associated with one or more of the vehicle system or a route over which the vehicle system moves based on the one or more encryption keys, and communicate the one or more encrypted messages from the onboard communication system to the off-board communication system.

摘要： A system may include a controller with one or more processors. The controller may determine the wheel size of a wheel of a vehicle during a trip. The one or more processors may communicate a message associated with the wheel size to an off-board device when the wheel size is below a threshold size.
