Abstract
A system includes a processor configured to access a train schedule to determine active train crossings along an original route, based on a predicted vehicle-arrival time at a given crossing. The processor is also configured to determine that a driver identity has an avoidance parameter associated therewith and determine a new route avoiding active train crossings, if possible, responsive to the avoidance parameter and determination of at least one active train crossing along the original route.
Claims12
A system comprising:
- a processor configured to:
- access a train schedule to determine active train crossings along an original route, based on a predicted vehicle-arrival time at a given crossing;
- determine that a driver identity has an avoidance parameter associated therewith;
- determine a new route avoiding active train crossings, if possible, responsive to the avoidance parameter and determination of at least one active train crossing along the original route;
- and
- engage active train-crossing safety controls when a vehicle approaches within a threshold distance of an active train crossing.
3 more elements
A system comprising:
- a processor configured to:
- determine that a current travel path includes an active train crossing based on expected train presence time;
- determine that a vehicle is within a braking threshold distance from the active train crossing;
- and
- automatically brake the vehicle, preventing forward movement of the vehicle until a train has cleared the train crossing, responsive to the vehicle being within the braking threshold distance.
2 more elements
A computer-implemented method comprising:
- determining, via a vehicle computer or a remote computer in communication with the vehicle computer, that a vehicle is within a threshold distance of an active train crossing, where a train is projected to arrive no later than a threshold time from a present time;
- and preventing the vehicle from entering a region defining a likely-impact region, responsive to the determining that the vehicle is within the threshold distance, until the vehicle computer determines that the train has cleared the crossing.
