  • Patent number: 10974748
    Abstract: A vehicle advisory system and method determine whether a vehicle system moving along a route is within a designated distance of a feature of interest, initiate a distance-based alert sequence of an advisory device of the vehicle system in response to determining that the vehicle system is at or within the designated distance of the feature of interest, and generate advisory signals using the advisory device according to the distance-based alert sequence. The advisory signals are indicative of passage of the vehicle system by the feature of interest during the distance-based alert sequence. The distance-based alert sequence dictates one or more of plural different commencement locations or commencement distances at which advisory signals are generated by the advisory device. The distance-based alert sequence also dictates one or more of plural different termination locations or termination distances where generation of the advisory signals by the advisory device is terminated.

  • Patent number: 10906570
    Abstract: A parking brake control module using pneumatic logic to control a parking brake on a vehicle. The control module includes a brake pipe passageway, a reservoir passageway, a reservoir release valve; and an actuation cylinder vent valve. The control module applies or releases the parking brake based on pressures of the brake pipe and reservoir. A method uses pneumatic logic to control a parking brake on a vehicle. The parking brake is applied when the brake pipe pressure falls below a lower brake pipe pressure threshold and is released when the brake pipe pressure exceeds an upper brake pipe pressure threshold and the reservoir pressure exceeds a reservoir pressure threshold. A hold valve can allow an operator to manually prevent the release of the parking brake.
