Abstract

A method and apparatus for assisting a driver of a first vehicle determines whether the first vehicle is traveling in a first lane of a multi-lane highway. The method further determines that another vehicle is approaching the first vehicle from behind in a second lane of the multi-lane highway. The method determines that the first vehicle is being passed by the second vehicle, and outputs a warning to the driver, instructing the driver to merge into the second lane where the second vehicle had been traveling.

Claims

providing a controller installed within the passenger vehicle, wherein the controller receives outputs from at least one of a camera and a radar device for detecting at least one of the location of the passenger vehicle, the location of a second vehicle, and the speed of the second vehicle, wherein the controller is in the form of a computer readable medium having instructions stored thereon and a processor that executes the instructions causing the controller to perform the steps of;

automatically detecting, by the controller performing a lane detect function and independent from driver or passenger perception, that the passenger vehicle is traveling on a roadway having at least two lanes for legally permissible public travel in a first direction including one or more predetermined passing lanes and a predetermined non-passing lane;

automatically detecting, by the controller performing the lane detect function and independent from driver or passenger perception, that the passenger vehicle is traveling in one of the one or more predetermined passing lanes of the at least two lanes;

automatically detecting, by the controller performing the vehicle detect function and independent from driver or passenger perception, that a second vehicle is behind the passenger vehicle and traveling in one of the at least two lanes;

automatically detecting, by the controller performing the vehicle detect function and independent from driver or passenger perception, that the second vehicle is traveling faster than the passenger vehicle;

automatically determining, by the controller based on outputs from the lane detect function and the vehicle detect function and independent from driver or passenger input, that the passenger vehicle is hindering traffic flow; and

in response to the controller determining that the passenger vehicle is hindering traffic, automatically outputting an instruction from the controller to depart from the predetermined passing lane toward the predetermined non-passing lane.

2. The method of claim 1, wherein the instruction comprises a warning that instructs the driver to merge toward the non-passing lane.

3. The method of claim 1, further comprising detecting

whether the passenger vehicle is engaged in stop-and-go traffic, and performing the method only in response to determining that the passenger vehicle is not engaged in the stop-and-go traffic.

4. The method of claim 1, further comprising detecting

whether the vehicle is traveling in a city environment or a highway environment, and performing the method only in response to determining that the passenger vehicle is traveling in the highway environment.

5. The method of claim 1, wherein the instruction is at least one of an audible warning, a text-based warning, and a haptic warning.

6. The method of claim 1, further comprising detecting, by the controller performing the lane detect function, whether the passenger vehicle is present in a directional lane, wherein a directional lane is a lane in which the driver is directed to be present for preparing to leave the roadway, and performing the method only in response to determining that the passenger vehicle is not present in a directional lane.

7. The method of claim 1, further comprising outputting an external warning to alert drivers of other vehicles that the passenger vehicle is being passed by other vehicles in the non-passing lane.

8. The method of claim 1, further comprising determining, by the controller performing the vehicle detect function, that the second vehicle has passed from behind the passenger vehicle to forward of the passenger vehicle, and the determining that the passenger vehicle is hindering traffic flow is performed in response to detecting that the second vehicle has passed from behind the passenger vehicle to forward of the passenger vehicle.

9. The method of claim 1, further comprising detecting, by the controller performing the vehicle detect function, that the second vehicle is approaching the passenger vehicle from behind in the same lane as the passenger vehicle, and the determining that the passenger vehicle is hindering traffic flow is performed in response to detecting that the second vehicle is approaching the passenger vehicle from behind.

10. The method of claim 1, wherein the outputting of the instruction is performed in the absence of an indication by the driver to depart the passing lane, wherein the indication is detected by the controller.

11. The method of claim 1, further comprising logging an instance in a database of the controller that the second vehicle has passed the passenger vehicle;

and detecting, by the controller performing the vehicle detect function, that at least one additional vehicle in addition to the second vehicle has passed the passenger vehicle and logging the at least one additional vehicle to define a number of passing vehicles.

12. A method for assisting a driver of a passenger vehicle, the method comprising:

providing a controller installed within the passenger vehicle, wherein the controller receives outputs from at least one of a camera and a radar device for detecting at least one of the location of the passenger vehicle, the location of a second vehicle, and the speed of the second vehicle, wherein the controller is in the form of a computer readable medium having instructions stored thereon and a processor that executes the instructions causing the controller to perform the steps of;

automatically detecting, by the controller performing the lane detect function and independent from driver or passenger perception, that the passenger vehicle is traveling;

automatically detecting, by the controller performing the lane detect function, that the passenger vehicle is traveling in a passing lane of the at least two lanes;

automatically detecting, by the controller performing a vehicle detect function and independent from driver or passenger perception, that the second vehicle is traveling in a non-passing lane of the at least two lanes, wherein the non-passing lane is different than the passing lane;

automatically detecting, by the controller performing a vehicle detect function and independent from driver or passenger perception, that the second vehicle is behind the passenger vehicle;

automatically detecting, by the controller performing the vehicle detect function and independent from driver or passenger perception, that the second vehicle is traveling faster than the passenger vehicle;

automatically detecting, by the controller performing the vehicle detect function and independent from driver or passenger perception, that the second vehicle has passed and is ahead of the passenger vehicle

automatically outputting a warning from the controller to the driver, wherein the warning instructs the driver to depart from the passing lane after detecting that the second vehicle is ahead of the passenger vehicle;

logging an instance in a database of the controller that the second vehicle has passed the passenger vehicle;

automatically detecting, by the controller performing the vehicle detect function and Independent from driver or passenger perception, that at least one additional vehicle in addition to the second vehicle has passed the passenger vehicle and logging the at least one additional vehicle to define a number of passing vehicles;

wherein the outputting the warning is performed in response to logging that the second vehicle and the at least one additional vehicle has passed the passenger vehicle.

13. The method of claim 12, wherein the outputting the warning is performed in response to the number of passing vehicles exceeding a predetermined threshold level.

14. The method of claim 12, further comprising measuring an elapsed time from a time corresponding to the logging in the database of the instance of the second vehicle passing the first vehicle, wherein the logging of the instance of the second vehicle passing the first vehicle comprises an initial instance.

15. The method of claim 14, further comprising clearing the log in response to the elapsed time exceeding a predetermined level, wherein the log is cleared in response to detecting no further vehicles in addition to the second vehicle during the elapsed time, wherein a further instance of detecting a further second vehicle passing the passenger vehicle after the elapsed time comprises the initial instance.

16. An apparatus for providing lane discipline assistance to a driver of a first vehicle, the apparatus comprising, the apparatus receiving outputs from at least one of a camera and a radar device for detecting at least one of the location of the passenger vehicle, the location of a second vehicle, and the speed of the second vehicle, a computer readable medium having instructions stored thereon that, when executing by a computing device, cause the computing device to perform steps comprising:
