Abstract

A system for indicating braking intensity to a main vehicle has an observational device monitoring positional and speed data of at least one vehicle proximate the main vehicle. A control unit is coupled to the observational device. The control unit processes the positional and speed data monitored by the observational device and generates graphical representations of the at least one vehicle proximate the main vehicle and graphical representations of a braking intensity level of the at least one vehicle proximate the main vehicle.

Claims

1. A system for indicating braking intensity to a main vehicle comprising:

an observational device monitoring positional and speed data of at least one vehicle proximate the main vehicle; and

a control unit coupled to the observational device processing the positional and speed data monitored by the observational device and generating graphical representations of the at least one vehicle proximate the main vehicle, graphical representations of a braking intensity level of the at least one vehicle proximate the main vehicle, and graphical representations of an alternate pathway for the main vehicle preventing a possible collision with the at least one vehicle proximate the main vehicle, wherein the graphical representations of the alternate pathway comprises a lane indicator, wherein the lane indicator illustrates which traffic lane adjacent to the main vehicle is clear for the main vehicle to enter.

2. The system of claim 1, wherein the lane indicator is positioned on a side of the traffic lane adjacent to the main vehicle that is unsafe to change.

3. The system of claim 1, wherein the graphical representations indicating the braking intensity of the at least one vehicle proximate the main vehicle comprises an indicator, wherein a length of the indicator depicts the braking intensity level.

4. The system of claim 1, wherein the graphical representations indicating the braking intensity of the at least one vehicle proximate the main vehicle comprises an indicator, wherein a color of the indicator varies depicting the braking intensity level.

5. The system of claim 1, wherein the observational device comprises a plurality of monitoring sensors coupled to the main vehicle and the control unit for monitoring at least one of position or speed of the at least one vehicle proximate the main vehicle.

6. The system of claim 1, wherein the observational device comprises a vehicle to vehicle (V2V) communication system wirelessly communicating speed and positional data between the main vehicle and the at least one vehicle proximate the main vehicle.

7. The system of claim 1, comprising a display coupled to the control unit showing the graphical representations of the at least one vehicle proximate the main vehicle and the graphical representations of the braking intensity level of the at least one vehicle proximate the main vehicle.

8. The system of claim 1, comprising a heads up display (HUD) coupled to the control unit showing the graphical representations of the at least one vehicle proximate the main vehicle and the graphical representations of the braking intensity level of the at least one vehicle proximate the main vehicle.

9. A system for indicating braking intensity to a main vehicle comprising:

an observational device monitoring positional and speed data of at least one vehicle proximate the main vehicle;

a control unit coupled to the observational device processing the positional and speed data monitored by the observational device and generating graphical representations of the at least one vehicle proximate the main vehicle, graphical representations of a braking intensity level of the at least one vehicle proximate the main vehicle, and graphical representations of an alternate pathway for the main vehicle preventing a possible collision with the at least one vehicle proximate the main vehicle, wherein the graphical representations of the alternate pathway comprises a lane indicator, wherein the lane indicator illustrates which traffic lane adjacent to the main vehicle is clear for the main vehicle to enter; and

a display coupled to the control unit showing the graphical representations of the at least one vehicle proximate the main vehicle and the graphical representations of the braking intensity level of the at least one vehicle proximate the main vehicle.

10. The system of claim 9, wherein the graphical representations indicating the braking intensity of the at least one vehicle proximate the main vehicle comprises an indicator, wherein a length of the indicator depicts the braking intensity level.

11. The system of claim 9, wherein the graphical representations indicating the braking intensity of the at least one vehicle proximate the main vehicle comprises an indicator, wherein a color of the indicator varies illustrating the braking intensity level.

12. The system of claim 9, wherein the observational device comprises a plurality of monitoring sensors coupled to the main vehicle and the control unit monitoring at least one of position or speed of the at least one vehicle proximate the main vehicle.

13. The system of claim 9, wherein the observational device comprises a vehicle to vehicle (V2V) communication system wirelessly communicating speed and positional data between the main vehicle and the at least one vehicle proximate the main vehicle.

14. A system for indicating braking intensity to a main vehicle comprising:

an observational device monitoring positional and speed data of at least one vehicle proximate the main vehicle; and

a control unit coupled to the observational device processing the positional and speed data monitored by the observational device and generating graphical representations of the at least one vehicle proximate the main vehicle, graphical representations of a braking intensity level of the at least one vehicle proximate the main vehicle, wherein the graphical representations indicating the braking intensity of the at least one vehicle proximate the main vehicle comprises an indicator, wherein one of a length of the indicator depicts the braking intensity level or a color of the indicator varies to depict the braking intensity level, and graphical representations of an alternate pathway for the main vehicle preventing a possible collision with the at least one vehicle proximate the main vehicle, wherein the graphical representations of the alternate pathway comprises a lane indicator and the lane indicator is positioned on a side of a traffic lane adjacent to the main vehicle that is unsafe to change.

15. The system of claim 14, wherein the observational device comprises a plurality of monitoring sensors coupled to the main vehicle and the control unit monitoring at least one of position or speed of the at least one vehicle proximate the main vehicle.

16. The system of claim 14, wherein the observational device comprises a vehicle to vehicle (V2V) communication system wirelessly communicating speed and positional data between the main vehicle and the at least one vehicle proximate the main vehicle.
