Abstract

A distracted driver notification system, a vehicle and a method of notifying a distracted driver. The system includes a communication system made up of one or both of an antenna and numerous sensors such that the communication system acquires data that is indicative of actual or expected vehicular movement in a traffic situation. The acquired data is conveyed to a computer for processing to determine if a traffic situation is present, as well as a change in status of such situation. The acquired or processed data may also be used to determine if a driver should be moving the vehicle in response to a change in the status of the traffic condition. A human-machine interface may include one or more of visual, haptic and audio configured to alert a distracted driver to start moving a vehicle that is equipped with the system, the alert based on a change in status of the traffic situation as acquired by the communication system and processed by the computer where such change is conducive to the movement of the vehicle, the system configured such that such alert is not provided when the vehicle is not in a traffic situation.

Claims

1. A driver notification system comprising:

a computer configured to;

determine a location of a vehicle;

determine the vehicle is stopped;

determine if the vehicle is in a traffic situation wherein a freedom of forward movement of at least one adjacent vehicle is hindered by the vehicle; and

determine whether to alert a driver to start moving the vehicle based on the determined location of the vehicle, the traffic situation, and in response to determining the vehicle is stopped; and

a human-machine interface responsive to the computer and configured to alert the driver to start moving the vehicle in response to the computer determining to alert the driver to start moving the vehicle.

2. The system of claim 1 further comprising:

a communication system comprising at least one of an antenna and a plurality of sensors, the communication system configured to acquire data that provides indicia of actual or expected vehicular movement in a traffic situation, wherein;

the computer is signally cooperative with the communication system to process data received therefrom; and

the computer is configured to make the determination as to whether to alert the driver to start moving the vehicle by comparing a change in status of the traffic situation that is conducive to the movement of the vehicle with whether the vehicle is undertaking such movement.

3. The system of claim 2, wherein the communication system comprises both the antenna and the plurality of sensors, at least one of which comprises a forward-looking sensor configured to detect a change in status of a traffic light such that when the traffic light changes from red to green, a first measure of the change in status of the traffic situation is achieved.

4. The system of claim 2, wherein the communication system comprises the plurality of sensors, wherein at least one sensor of the plurality of sensors comprises a forward-looking sensor configured to detect a change in status of brake lights in at least one vehicle forward of the vehicle such that when the brake light status changes from engaged to disengaged, a second measure of the change in status of the traffic situation is achieved.

5. The system of claim 2, wherein the communication system comprises the plurality of sensors, wherein at least one sensor of the plurality of sensors comprises a forward-looking sensor configured to detect a distance between the vehicle and at least one vehicle forward of the vehicle such that when the distance is more than a threshold value, a third measure of the change in status of the traffic situation is achieved.

6. The system of claim 2, wherein the communication system comprises the plurality of sensors, wherein at least one sensor of the plurality of sensors comprises a forward-looking sensor configured to detect a rate of separation between the vehicle and at least one vehicle forward of the vehicle such that when the rate of separation is more than a threshold value, a fourth measure of the change in status of the traffic situation is achieved.

7. The system of claim 2, wherein the communication system comprises the plurality of sensors, wherein the plurality of sensors is selected from the group consisting of optical sensors, acoustic sensors, lidar sensors, radar sensors, infrared sensors and combinations thereof.

8. The system of claim 3, wherein the change in status of the traffic situation as acquired by the plurality of sensors and processed by the computer is determined by a change in status of at least two of a traffic control device, a brake light status in at least one vehicle forward of the vehicle, a distance between the vehicle and the at least one vehicle forward of the vehicle and a rate of separation between the vehicle and the at least one vehicle forward of the vehicle.

9. The system of claim 1, wherein the location of the vehicle is determined based on navigational data.

10. The system of claim 9, the computer is configured to:

determine the location of the vehicle is in a parking lot based on the navigational data; and

determine not to alert the driver to start moving the vehicle when the location of the vehicle is determined to be in the parking lot.

11. The system of claim 10, the computer is configured to:

determine the location of the vehicle is in at least one of a driveway and a garage of a private residence based on the navigational data; and

determine not to alert the driver to start moving the vehicle when the location of the vehicle is determined to be in at least one of the driveway and the garage of the private residence.

12. The system of claim 2, wherein the alert comprises at least one of an audible and visual alert conveyed to the driver after a computer-initiated delay.

13. The system of claim 2, wherein when the vehicle is not in a traffic situation, the system monitors the speed of the vehicle but does not alert the driver.

14. A vehicle comprising:

a platform comprising a wheeled chassis defining a passenger compartment and an engine compartment comprising an engine disposed therein,

a control apparatus cooperative with the wheeled chassis and the engine in order to provide motive control; and

a driver notification system comprising;

a computer configured to;

determine a location of the vehicle;

determine the vehicle is stopped;

determine if the vehicle is in a traffic situation wherein a freedom of forward movement of at least one adjacent vehicle is hindered by the vehicle; and

determine whether to alert a driver to start moving the vehicle based on the determined location of the vehicle, the traffic situation, and in response to determining the vehicle is stopped; and

a human-machine interface responsive to the computer and configured to alert the driver to start moving the vehicle in response to the computer determining to alert the driver to start moving the vehicle.

15. The vehicle of claim 14, wherein the alert comprises at least one of an audible, haptic and visual warning to the driver.

16. The vehicle of claim 14, further comprising a communication system comprising at least one of an antenna and a plurality of sensors, the communication system configured to acquire data that provides indicia of actual or expected vehicular movement in a traffic situation, wherein:

the computer is signally cooperative with the communication system to process data received therefrom; and

the computer is configured to make the determination as to whether to alert the driver to start moving the vehicle by comparing a change in status of the traffic situation that is conducive to the movement of the vehicle with whether the vehicle is undertaking such movement.

17. A method of notifying a driver, the method comprising:

determining a location of a vehicle with a computer;

determining the vehicle is stopped with the computer;

determining if the vehicle is in a traffic situation wherein a freedom of forward movement of at least one adjacent vehicle is hindered by the vehicle;
