Abstract: A vehicle monitoring device includes a camera or other optical sensor configured to be disposed at a trailing end of a first vehicle system. The camera or other optical sensor is configured to output one or more images or video of a field of view behind the first vehicle system. The monitoring device also includes a controller configured to receive output from one or more sensors and to activate the camera or other optical sensor to output the one or more images or video based on the output from the one or more sensors. The output from the one or more sensors indicates one or more of a change in movement of the first vehicle system, a temperature, an acoustic sound, or movement of a second vehicle system.

Abstract: A monitoring device detection system may include a mounting assembly disposed onboard a vehicle system. The mounting assembly couples a vehicle signaling and monitoring device to the vehicle system. One or more sensors may obtain information related to one or more of the mounting assembly or the vehicle system. One or more processors may determine a state of the mounting assembly based on the information obtained by the one or more sensors.

Abstract: A system is provided that may include a first communication controller that may communicate with a vehicle system formed from two or more vehicles. The first communication controller may operate in different modes, including a first mode to control movement of the vehicle system without repeating any control signals communicated between the vehicles, and in a second mode to monitor different frequencies for receipt of the control signals, receive and repeat a first control signal of the control signals at a first frequency, and receive and repeats a second control signal of the control signals at a second frequency. The first communication controller may also operate in a third mode in which the first communication controller may monitor the first frequency but not the second frequency for the first control signal, receives the first control signal at the first frequency, and repeats the first control signal at the first frequency.

Abstract: A vehicle system is provided that has an unoccupied control vehicle with no onboard driver. The control vehicle has a first propulsion system that can propel the control vehicle along a route, and optionally to stop or slow the control vehicle. One or more onboard power sources that can generate, store or both generate and store energy for powering at least the first propulsion system. A controller having one or more processors can autonomously control the propulsion system to move the control vehicle along one or more routes, and to interface with and couple to a driver-operable vehicle that has a second propulsion system. The controller can obtain control over the second propulsion system when the control vehicle is interfaced and coupled with the driver-operable vehicle.

Abstract: A system and method obtain first image data of a route at a location of interest from a first optical sensor disposed onboard a vehicle system moving along the route. The first image data depicts the route at the location of interest prior to passage of the vehicle system over the route at the location of interest. Second image data of the route at the location of interest is obtained from a second optical sensor disposed onboard the vehicle system. The second image data depicts the route at the location of interest after passage of the vehicle system over the route at the location of interest. A determination is made as to whether a change in the route has occurred at the location of interest by comparing the first image data with the second image data.

Abstract: A communication device and method may include at least one tuner circuit that monitors at least a first frequency channel and a second frequency channel. A controller of the radio receiver may measure a first received signal strength indicator (RSSI) value over time for the first frequency channel and a second RSSI value over time for the second frequency channel. The first and second RSSI values are based on a signal strength of radio frequency (RF) energy received on the first and second frequency channels, respectively. The controller may detect a leader portion of a message on the first frequency channel responsive to a change in the first RSSI value exceeding a step change threshold. The controller may extract, via a detector circuit, message data from a carrier wave of the RF message.

Abstract: A communication system may include communication devices configured to be onboard vehicles in a multi-vehicle system. Each of the communication devices may operate in a lead mode, a repeater mode, or a trail mode. The communication devices operating in the lead mode may transmit a command signal to control movement of the multi-vehicle system. The communication devices operating in the repeater mode may re-transmit the command signal received from the one or more communication devices operating in the lead mode. The communication devices operating in the trail mode may receive the command signal received from the one or more communication devices operating in the lead mode or in the repeater mode. Each of the communication devices may be remotely switched between the lead mode or the trail mode to the repeater mode.
