Abstract

The present invention discloses methods, apparatuses, and a system for improving intervehicular traffic safety by facilitating driver awareness of nearby vehicular traffic activity. Methods are disclosed for monitoring, detecting, and tracking “adjacent vehicles” (AVs) and “adjacent vehicle movements” (AVMs); calculating and displaying AV/AVM status data; and recommending and/or executing intervehicular maneuvering actions as needed. A driver-adjustable sensor apparatus is disclosed, allowing driver adjustment of AV/AVM “detection perimeters” (to increase/decrease detection ranges) based on traffic conditions, driver preferences, triggering of legal or preset thresholds, etc. Multiple versions of a “driver-adjustable” sensor and display system monitor, detect, and track traffic adjacent to a reference vehicle; calculate and display AV/AVM status data; and recommend and/or execute routine or emergency maneuvering actions needed to maintain vehicle safety during congestion or other intervehicular events. Better driver awareness and improved traffic safety are the result. The invention is factory-installed or purchased as an aftermarket product.

live”

AVM status data further comprises (but is not limited to) at least one of location data, direction of motion data, direction of relative motion data, range data, bearing data, speed data, closest point of approach data, closure rate data, collision probability data, and additional driver-stipulated data pertaining to at least one of said AVs when compared with a reference vehicle after detection of said at least one AV crossing within said at least one detection perimeter of said reference vehicle.

3. The method of claim 1, wherein the step of adjusting and setting said at least one detection perimeter also includes the step of setting at least one of a P1 detection perimeter and a P2 detection perimeter.

4. The method of claim 1, wherein the step of recommending and displaying said at least one maneuvering recommendation also includes the step of displaying at least one display screen showing successive AVM status data updates of said at least one AV crossing within said at least one detection perimeter.

5. The method of claim 1, wherein the step of calculating “

live”

AVM status data further includes providing data updates at a driver-selected update frequency and occurs while said reference vehicle is in motion.

6. The method of claim 1, wherein the step of calculating “

live”

AVM status data further includes providing data updates at a driver-selected update frequency and occurs while said reference vehicle is stopped.

7. The method of claim 4, further including the step of visually displaying a simulated overhead view of said at least one AV and displaying said successive AVM status data updates relevant to said at least one maneuvering recommendation.

8. The method of claim 7, further including at least one of the steps of audibly sounding a warning sound and visually displaying a warning image of said at least one maneuvering recommendation represented as pictographic data.

9. The method of claim 6, wherein display of said successive AVM status data updates includes (but is not limited to) at least one of course update data and a speed update data pertaining to said at least one AV.

10. The method of claim 1, additionally including the step of signaling and broadcasting IVMs (intended vehicle movements) by said reference vehicle, wherein said IVMs further comprise proposed intended vehicle movements of said reference vehicle to said AVs in advance of execution thereof.

11. The method of claim 10, further including the step of at least one of said AVs transmitting a challenge to IVMs broadcast by said reference vehicle, and wherein said signaling and broadcasting by said reference vehicle initiates an interactive challenge dialogue option for any of said AVs to challenge said IVMs broadcast by said reference vehicle.

12. A driver-adjustable sensor apparatus for monitoring, detecting and tracking AVs, for processing AVMs, for calculating AVM status data, and for recommending and displaying at least one maneuvering recommendation to a driver of a reference vehicle, comprising:
