Abstract

A method is disclosed for estimating the exposure of vehicle occupants to environmental conditions capable of inducing a least discomfort. The occupants are alerted to their proximity to a zone where environmentally-challenging conditions exist and, in a first embodiment, the details of the environmental condition and the estimated duration of any exposure is communicated to the occupants; in a second embodiment a suggested course of action by which the occupants may mitigate the effect of the environmental occurrence is communicated; and in a third embodiment the proposed course of action is automatically executed subject to override by the occupants.

Claims

1. A computer-based method of alerting occupants of a motor vehicle at a current location of their proximity to a region, the region having a known location and an extent, and being characterized by a known environmental condition whose nature and severity are known, the environmental condition being capable of inducing at least discomfort in an occupant of the vehicle, the method comprising:

identifying the current location of the vehicle;

comparing the current vehicle location with the known location and extent of the region with the known environmental condition;

determining whether the current location of the vehicle lies within a pre-selected distance of the region with the known environmental condition;

predicting, based on knowledge of current vehicle speed and route, and knowledge of the location and extent of the region, any potential for exposure of the vehicle occupants to the environmental condition; and

, if such potential exposure is predicted,

alerting the vehicle occupants of their proximity to the environmental condition and of their predicted potential exposure to the known environmental condition;

then,

estimating an expected duration of any potential exposure of the vehicle occupants to the known environmental condition; and

providing a visual display to the occupants of the vehicle of the nature and severity of the environmental condition and the estimate of the potential exposure duration.

2. The method of claim 1 in which the alert is an audible alert.

3. The method of claim 1, further comprising receiving broadcast information regarding the extent and environmental condition of a region upon request of a vehicle occupant.

4. A computer-based method of communicating predetermined remedial actions to the occupants of a motor vehicle at a current location when the vehicle is determined to be within a preselected distance of a region;

the region having a known extent and location, and being characterized by an environmental condition whose nature and severity are known;

the environmental condition being capable of inducing at least discomfort in an occupant of the vehicle, the method comprising;

identifying the current location of the vehicle;

comparing the current vehicle location with the known location of the region with the known environmental condition;

determining whether the current location of the vehicle lies within the pre-selected distance of the region;

predicting, based on knowledge of current vehicle speed and route and knowledge of the extent and location of the region, the duration of any potential exposure to the known environmental condition characteristic of the region; and

, if such potential exposure is predicted,

comparing the nature, potential exposure duration and severity of the known environmental condition characterizing the region to which the occupants are potentially exposed to a stored listing of environmental conditions, the listing comprising a plurality of entries, each entry having associated data comprising an environmental condition and its severity, an exposure duration and at least one remedial action; and

when a listed environmental condition entry substantially corresponding to the predicted potential environmental condition exposure, exposure duration and severity is found, communicating the associated remedial action for that entry to the vehicle occupants.

5. The method of claim 4 further comprising automatically executing the associated remedial action.

6. The method of claim 4 comprising requesting authorization from the occupants prior to automatically executing the associated remedial action.

7. The method of claim 4 in which the associated remedial action is one or more of:

determining an alternate route;

closing windows and sunroofs;

shutting off a passenger compartment ventilation fan;

raising the operating speed of a passenger compartment ventilation fan; and

supplying additional oxygen to a passenger compartment.

8. The method of claim 4, further comprising receiving broadcast information regarding the extent and environmental condition of a region upon request of a vehicle occupant.

9. A computer-based method of communicating predetermined remedial actions to the occupants of a motor vehicle at a current location when the vehicle is determined to be within a preselected distance of a region;

the region having a known extent and location and being characterized by an environmental condition whose nature and severity are known;

the environmental condition being capable of inducing at least discomfort in an occupant of the vehicle, the method comprising;

receiving data on a region characterized by an environmental condition;

identifying the current location of the vehicle;

comparing the current vehicle location with the known location of the region with the known environmental condition;

determining whether the current location of the vehicle lies within the pre-selected distance of the region;

predicting, based on knowledge of current vehicle speed and route, and knowledge of the extent of the region, the duration of any potential exposure to the environmental condition characteristic of the region; and

, if such potential exposure is predicted,

comparing the nature, potential exposure duration and severity of the known environmental condition characterizing the region to which the occupants are potentially exposed to a stored listing of environmental conditions, the listing comprising a plurality of entries, each entry having associated data comprising an environmental condition and its severity, an exposure duration and at least one remedial action; and

when a listed environmental condition entry substantially corresponding to the predicted potential environmental condition exposure, exposure duration and severity is found, communicating the associated remedial action for that entry to the vehicle occupants.

10. The method of claim 9, the method further comprising requesting data on at least a region characterized by an environmental condition.

11. The method of claim 9 further comprising automatically executing the associated remedial action.

12. The method of claim 11 in which the associated remedial action is one or more of:

determining an alternate route;

closing windows and sunroofs;

shutting off a passenger compartment ventilation fan;

raising the operating speed of a passenger compartment ventilation fan; and

supplying additional oxygen to a passenger compartment.

13. The method of claim 9 comprising requesting authorization from the occupants prior to automatically executing the associated remedial action.
