Method and system of monitoring passenger buses
A method of monitoring passenger buses includes generating host vehicle information with a navigation unit, the host vehicle information including a host vehicle location and a host vehicle heading, receiving passenger bus information with a receiver, the passenger bus information including an passenger bus status, a passenger bus location and a passenger bus heading, determining with a controller a distance between the host vehicle location and the passenger bus location, determining with the controller whether the distance between host vehicle location and the passenger bus location is decreasing, and performing a mitigation operation, when the distance between host vehicle location and the passenger bus location is decreasing, and the distance between host vehicle location and the passenger bus location is a threshold distance or less.
1. A passenger bus monitoring method comprising:
generating host vehicle information with a navigation unit, the host vehicle information including a host vehicle location and a host vehicle heading;
receiving passenger bus information with a receiver, the passenger bus information including an indication of a change in a passenger bus operation status, a passenger bus location and a passenger bus heading;
determining with a controller a distance between the host vehicle location and the passenger bus location;
determining with the controller whether the distance between host vehicle location and the passenger bus location is decreasing, and whether the host vehicle trajectory will cause the host vehicle to pass the passenger bus; and
performing a mitigation operation by the host vehicle, when the indication of the change in a passenger bus operation status is received, when the distance between host vehicle location and the passenger bus location is decreasing, when the host vehicle trajectory will cause the host vehicle to pass the passenger bus without a threat of contact between the host vehicle and the passenger bus, and the distance between host vehicle location and the passenger bus location is a threshold distance or less.
2. The method according to claim 1 , further comprising
ceasing the mitigation operation based on a predetermined condition.
3. The method according to claim 2 , wherein
the predetermined condition is another change in the passenger bus operation status.
4. A passenger bus monitoring method comprising:
generating host vehicle information with a navigation unit, the host vehicle information including a host vehicle location and a host vehicle heading;
receiving passenger bus information with a receiver, the passenger bus information including a passenger bus status, a passenger bus location and a passenger bus heading;
determining with a controller a distance between the host vehicle location and the passenger bus location;
determining with the controller whether the distance between host vehicle location and the passenger bus location is decreasing;
performing a mitigation operation by the host vehicle, when the distance between host vehicle location and the passenger bus location is decreasing, and the distance between host vehicle location and the passenger bus location is a threshold distance or less without a threat of contact between the host vehicle and the passenger bus; and
ceasing the mitigation operation based on a predetermined condition, the predetermined condition being a deactivation of passenger bus caution lights.
5. The method according to claim 2 , further comprising
performing an intervention operation when the distance between the host vehicle location and the passenger bus location is decreasing, and the distance between the host vehicle location and the passenger bus location is a second threshold distance or less.
6. The method according to claim 5 , wherein
the second threshold distance is less than the first threshold distance.
7. The method according to claim 6 , further comprising
ceasing the intervention operation based on the predetermined condition.
8. The method according to claim 7 , wherein
the predetermined condition is a change in the passenger bus operation status.
9. The method according to claim 5 , wherein
the performing the intervention operation includes at least one of braking the host vehicle and altering the trajectory of the host vehicle.
10. The method according to claim 5 , wherein
the performing the intervention operation includes maintaining at least the second threshold distance between the host vehicle location and the passenger bus location.
11. The method according to claim 10 , further comprising
determining with the controller jurisdictional rules with respect to passenger buses at the host vehicle location.
12. The method according to claim 11 , wherein
determining with the controller the jurisdictional rules includes determining the jurisdictional distance to be maintained between the host vehicle location and the passenger bus location.
13. The method according to claim 12 , wherein
the performing the intervention operation includes operating brakes of the host vehicle to maintain the second threshold distance.
14. The method according to claim 12 , wherein
the performing the intervention operation includes altering the trajectory of the host vehicle to maintain the second threshold distance.
15. The method according to claim 2 , wherein
the predetermined condition is a ceasing of a caution state.
16. The method according to claim 15 , wherein
the ceasing of the caution state includes retracting a stop sign while maintaining the activation of caution lights.
17. The method according to claim 1 , further comprising
determining with the controller jurisdictional rules with respect to passenger bus at the host vehicle location.
18. The method according to claim 17 , wherein
the performing the mitigation operation includes notifying occupants of the host vehicle of the jurisdictional rules.
19. The method according to claim 1 , wherein
the activating the advisory includes activating an interior warning.
20. The method according to claim 1 , wherein
the activating the advisory includes activating an auditory advisory.
