Abstract

A blind zone mitigation system of a host vehicle comprises i) at least one sensor that determines position information of a target vehicle with respect to the host vehicle, and ii) an active lane positioning module. The active lane positioning module receives the position information from the at least one sensor and determines a blind zone of the target vehicle. The active lane positioning module, in an active lane position mode, accelerates the host vehicle to move the host vehicle out of the blind zone of the target vehicle or decelerates the host vehicle to move the host vehicle out of the blind zone of the target vehicle.

Claims

1. A blind zone mitigation system of a host vehicle, comprising:

at least one sensor configured to determine position information of a target vehicle with respect to the host vehicle; and

an active lane positioning module configured to receive the position information from the at least one sensor and to determine a blind zone of the target vehicle and to determine if the host vehicle will be in the blind zone for a time period greater than a threshold value, wherein the active lane positioning module, in response to a determination that the host vehicle will be in the blind zone for a time period greater than the threshold value, is further configured, in an active lane position mode, to one of;

accelerate the host vehicle to reduce an amount of time the host vehicle will spend in the blind zone to less than the threshold value;

decelerate the host vehicle to reduce an amount of time the host vehicle will spend in the blind zone to less than the threshold value;

or

decelerate the host vehicle to prevent the host vehicle from entering the blind zone.

2. The blind zone mitigation system of claim 1, wherein the active lane positioning module is further configured, in a passive alert mode, to generate a driver notification to alert the driver that the host vehicle is, or will be, in the blind zone.

3. The blind zone mitigation system of claim 2, wherein the active lane positioning module generates the driver notification in response to a determination that the host vehicle will be in the blind zone for a time period greater than the threshold value.

4. The blind zone mitigation system of claim 2, wherein the driver notification comprises at least one of:

i) an audible alarm, ii) a visual alarm, and iii) a haptic alarm.

5. The blind zone mitigation system of claim 1, wherein the active lane positioning module is configured to communicate with a cruise control module of the host vehicle to cause the host vehicle to accelerate or decelerate.

6. The blind zone mitigation system of claim 5, wherein the active lane positioning module is further configured, in an active lane position mode, to move the host vehicle from higher risk zone in a first lane to a lower risk zone in a second lane.

7. A blind zone mitigation system of a host vehicle, comprising:

at least one sensor configured to determine position information of a plurality of target vehicles with respect to the host vehicle; and

an active lane positioning module configured to receive the position information from the at least one sensor and to determine a blind zone of a first target vehicle, wherein the active lane positioning module is further configured, in an active lane position mode, to determine if decelerating the host vehicle will create a blind zone with a second target vehicle and;

in response to a determination that decelerating the host vehicle will not create a blind zone with the second target vehicle, to decelerate the host vehicle to move the host vehicle out of the blind zone of the first target vehicle;

in response to a determination that decelerating the host vehicle will create a blind zone with the second target vehicle, to further determine if accelerating the host vehicle will create a blind zone with a third target vehicle and, in response to a determination that accelerating the host vehicle will not create a blind zone with the third target vehicle, accelerating the host vehicle to move the host vehicle out of the blind zone of the first target vehicle.

8. The blind zone mitigation system of claim 7, wherein the active lane positioning module is further configured, in a passive alert mode, to generate a driver notification to alert the driver that the host vehicle is, or will be, in the blind zone of the first target vehicle.

9. The blind zone mitigation system of claim 8, wherein the active lane positioning module is further configured to determine if the host vehicle will be in the blind zone of the first target vehicle for a time period greater than a threshold value, and to generate the driver notification in response to a determination that the host vehicle will be in the blind zone of the first target vehicle for a time period greater than the threshold value.

10. The blind zone mitigation system of claim 8, wherein the driver notification comprises at least one of:

i) an audible alarm, ii) a visual alarm, and iii) a haptic alarm.

11. The blind zone mitigation system of claim 7, wherein the active lane positioning module is further configured to determine if the host vehicle will be in the blind zone of the first target vehicle for a time period greater than a threshold value.

12. The blind zone mitigation system of claim 11, wherein the active lane positioning module, in response to a determination that the host vehicle will be in the blind zone of the first target vehicle for a time period greater than the threshold value, accelerates the host vehicle to reduce an amount of time the host vehicle will spend in the blind zone of the first target vehicle to less than the threshold value.

13. The blind zone mitigation system of claim 11, wherein the active lane positioning module, in response to a determination that the host vehicle will be in the blind zone of the first target vehicle for a time period greater than the threshold value, decelerates the host vehicle to reduce an amount of time the host vehicle will spend in the blind zone of the first target vehicle to less than the threshold value.

14. The blind zone mitigation system of claim 11, wherein the active lane positioning module, in response to a determination that the host vehicle will be in the blind zone of the first target vehicle for a time period greater than the threshold value, decelerates the host vehicle to prevent the host vehicle from entering the blind zone of the first target vehicle.

15. The blind zone mitigation system of claim 7, wherein the active lane positioning module is configured to communicate with a cruise control module of the host vehicle to cause the host vehicle to accelerate or decelerate.

16. The blind zone mitigation system of claim 15, wherein the active lane positioning module is further configured, in an active lane position mode, to move the host vehicle from higher risk zone in a first lane to a lower risk zone in a second lane.
