Abstract

In at least one embodiment, an apparatus for providing a space management alert for a host vehicle is provided. The apparatus comprises a controller configured to determine whether a first vehicle positioned ahead of the host vehicle is in a first detection zone and to determine whether a second vehicle positioned on one of a left side and a right side of the host vehicle is in a second detection zone. The controller is further configured to determine that the host vehicle is in a high density traffic condition (HDTC) if the first vehicle is in the first detection zone and the second vehicle is in the second detection zone and to selectively disable a space management alert when the host vehicle is in the HDTC.

Claims

1. An apparatus for providing a space management alert for a host vehicle, the apparatus comprising:

a controller configured to;

determine whether a first vehicle positioned ahead of the host vehicle is in a first detection zone;

determine whether a second vehicle positioned on one of a left side and a right side of the host vehicle is in a second detection zone;

determine that the host vehicle is in a high density traffic condition (HDTC) if the first vehicle is in the first detection zone and the second vehicle is in the second detection zone; and

selectively disable the space management alert when the host vehicle is in the HDTC.

2. The apparatus of claim 1 wherein the first detection zone corresponds to the first vehicle being positioned within a predetermined gap of the host vehicle for a first time period that is greater than a first predetermined time value.

3. The apparatus of claim 2 wherein the second detection zone corresponds to the second vehicle being positioned within the one of the left side and the right side of the host vehicle for a second time period that is greater than a second predetermined time value.

4. The apparatus of claim 1 wherein the controller is further configured to monitor at least one signal to determine if the vehicle is in a distracted state.

5. The apparatus of claim 4 wherein the at least one signal corresponds to at least one of a Driver'"'"'s Impairment Monitor (DIMON) signal which is indicative of the host vehicle'"'"'s variation within a lane on a road, an occupant communication device (OCD) status signal which is indicative of whether a driver of the host vehicle is using an OCD, an infotainment signal which is indicative of the whether driver of the host vehicle is attempting to adjust a setting of an infotainment system, and a climate control signal which is indicative of whether the driver of the host vehicle is attempting to manipulate a setting related to a climate control system of the vehicle.

6. The apparatus of claim 4 wherein the controller is further configured to generate the space management alert if the host vehicle is in the HDTC and in the distracted state.

7. The apparatus of claim 1 wherein the controller is further configured to monitor a front gap between the host vehicle and the first vehicle and to determine whether the front gap has decreased for a time period that exceeds a predetermined time period.

8. The apparatus of claim 7 wherein the controller is further configured to generate the space management alert if the host vehicle is in the HDTC and if the front gap has decreased for a time period that exceeds the predetermined time period.

9. The apparatus of claim 1 further comprising a forward collision warning (FCW) system configured to transmit a gap signal indicative of a gap between the host vehicle and the first vehicle, the controller being configured to determine if the host vehicle is in the first detection zone based on at least the first signal.

10. The apparatus of claim 9 further comprising a blind spot monitoring (BMS) system configured to transmit a BSM signal indicating that the second vehicle is within a location zone of the host vehicle, the controller being configured to determine if the host vehicle is in the second detection zone based on at least the BSM signal.

11. A method comprising:

determining whether a first vehicle positioned ahead of a host vehicle is in a first detection zone and a second vehicle positioned on one of a left side and a right side of the host vehicle is in a second detection zone;

determining that the host vehicle is in a high density traffic condition (HDTC) if the first vehicle is in the first detection zone and the second vehicle is in the second detection zone; and

selectively disabling a space management alert when the host vehicle is in the HDTC.

12. The method of claim 11 wherein the first detection zone corresponds to the first vehicle being positioned within a predetermined gap of the host vehicle for a first time period that is greater than a first predetermined time value.

13. The method of claim 12 wherein the second detection zone corresponds to the second vehicle being positioned within the one of the left side and the right side of the host vehicle for a second time period that is greater than a second predetermined time value.

14. The method of claim 11 further comprising monitoring at least one signal to determine if the host vehicle is in a distracted state.

15. The method of claim 14 wherein the at least one signal corresponds to at least one of a Driver'"'"'s Impairment Monitor (DIMON) signal which is indicative of the host vehicle'"'"'s variation within a lane on a road, an occupant communication device (OCD) status signal which is indicative of whether a driver of the host vehicle is using an OCD, an infotainment signal which is indicative of the whether driver of the host vehicle is attempting to adjust a setting of an infotainment system, and a climate control signal which is indicative of whether the driver of the host vehicle is attempting to manipulate a setting related to a climate control system of the vehicle.

16. The method of claim 14 further comprising generating the space management alert if the host vehicle is in the HDTC and in the distracted state.

17. The method of claim 11 further comprising monitoring a front gap between the host vehicle and the first vehicle to determine whether the front gap has decreased for a time period that exceeds a predetermined time period in response to determining that the host vehicle is in the HDTC.

18. The method of claim 17 further comprising generating the space management alert if the host vehicle is in the HDTC and if the front gap has decreased for a time period that exceeds the predetermined time period.

19. An apparatus comprising:

a controller configured to;

receive a gap signal indicative of a front gap between a host vehicle and a first vehicle;

determine whether the front gap decreases over a predetermined time period;

determine that the host vehicle is experiencing a cutoff condition in response to the front gap decreasing over the predetermined time period; and

selectively disable transmitting a space management alert if the host vehicle is experiencing a cutoff condition.

20. The apparatus of claim 19 wherein the controller is further configured to receive a lane departure signal indicative of the host vehicle intentionally merging into another lane and the controller is further configured to selectively disable transmitting the space management alert if the host vehicle is intentionally merging into another lane.
