Vehicle intersection warning system and method with false alarm suppression
First Claim
1. A method for providing information to a driver of a vehicle, comprising:
- obtaining information that describes a queue of stopped vehicles that are waiting to traverse a first path, wherein the queue of stopped vehicles includes a host vehicle;
obtaining conflicting vehicle information that describes a second path to be traversed by a potentially conflicting vehicle, wherein the second path crosses the first path at a convergence point;
determining a queue length representing a number of vehicles from the queue of stopped vehicles that are located ahead of the host vehicle;
determining an anticipated travel time for travel of the potentially conflicting vehicle to the convergence point; and
causing a warning alert to be output if the anticipated travel time for travel of the potentially conflicting vehicle to the convergence point is less than a warning alert time value and only if the queue length is equal to or less than a warning alert length value.

Abstract
A method for providing information to a driver of a vehicle includes obtaining host vehicle information that describes a first path to be traversed by a host vehicle, obtaining conflicting vehicle information that describes a second path to be traversed by a potentially conflicting vehicle, wherein the second path crosses the first path, determining a queue length representing a number of queued vehicles that are queued ahead of the host vehicle, determining a time-to-contact based on the host vehicle information and the conflicting vehicle information, and causing a warning alert to be output if the time-to-contact is less than a warning alert time value and the queue length is equal to or less than a warning alert length value.

10. A system, comprising:
-
a wireless electronic communication device that is located in a host vehicle; one or more sensors that are located in the host vehicle; an output system that is located in the host vehicle and includes at least one of an audio output device or a visual output device; and an information system that is located in the host vehicle and is operable to execute instructions that cause the information system to; obtain information from the one or more sensors, wherein the information describes a queue of stopped vehicles that are waiting to traverse a first path, wherein the queue of stopped vehicles includes the host vehicle, obtain conflicting vehicle information that describes a second path to be traversed by a potentially conflicting vehicle, wherein the second path crosses the first path at a convergence point, determine a queue length representing a number of vehicles from the queue of stopped vehicles that are located ahead of the host vehicle, determine an anticipated travel time for travel of the potentially conflicting vehicle to the convergence point, and cause a warning alert to be output using the output system if the anticipated travel time for travel of the potentially conflicting vehicle to the convergence point is less than a warning alert time value and only if the queue length is equal to or less than a warning alert length value. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18)

19. A system, comprising:
a host vehicle that includes a wireless electronic communication device, one or more sensors that output host vehicle information, an output system that includes at least one of an audio output device or a visual output device, and an information system that is operable to execute instructions that cause the information system to; determine, based on the host vehicle information, that the host vehicle is waiting in a queue of stopped vehicles to follow a first path through a roadway intersection, determine, based on remote vehicle information obtained from remote vehicles, that a potentially conflicting vehicle will cross the first path at a convergence point, determine an anticipated travel time for travel of the potentially conflicting vehicle to the convergence point, and cause a warning alert to be output using the output system if the anticipated travel time for travel of the potentially conflicting vehicle to the convergence point is less than a warning alert time value and only if zero vehicles are present ahead of the host vehicle in the queue of stopped vehicles. - View Dependent Claims (20)
