摘要： A system for reducing wheel sliding on a locomotive is provided for a locomotive including a plurality of axles. The system includes one or more speed inferring systems coupled to each axle to detect rotation of each axle and generate detection signals based upon detecting rotation of each axle. The detection signals include one of speed signals indicative of locomotive speed and non-rotating signals indicative of a non-rotating axle. More particularly, a main controller is coupled to each speed inferring system and is responsive to each detection signal. The main controller identifies non-rotating signals of the detection signals to initiate one or more alert signals of one or more respective non-rotating axles of the plurality of axles. Additionally, the main controller is coupled to an operator panel to alert a locomotive operator of an applied status of a locomotive parking brake in response to the alert signal.

摘要： The present invention discloses a back-propagating intersection collision avoidance (ICA) system for preventing two or more vehicles from colliding at an intersection. The ICA system can calculate predicted positions of the two or more vehicles in the near future, and both the current and future positions can be broadcast to surrounding vehicles using vehicle-to-vehicle communication. For each vehicle, a set of states, for example position, speed, acceleration, and the like, where a collision is imminent can be identified using state information for a local vehicle, a remote vehicle, and a known collision zone for the intersection. If the current states of the vehicles are determined to be in danger of entering the collision zone, the ICA system can control the vehicles to perform evasive driving maneuvers and/or alert the drivers.
