Abstract

A haptic alert system for use in a vehicle includes a sensor system operable to identify a condition associated with the vehicle; a control system in communication with the sensor system; and a remote haptic device in communication with the sensor system.

First claim

What is claimed:

1. An alert system for a vehicle, comprising:
a sensor system operable to identify conditions associated with the vehicle, the sensor system including:
at least one of an eye monitoring sensor and a facial recognition sensor operable to identify whether a driver of the vehicle is impaired,
a lane monitoring device operable to identify whether the vehicle is straying from a lane, and
a distance measurement device operable to identify a closing rate relative to another vehicle;

an in-vehicle alert system, the in-vehicle alert system operable to provide at least one of an audible or a visual alert to the driver;
a remote haptic device, the remote haptic device carriable or wearable by the driver, and operable to provide an alert to the driver when carried or worn; and
a control system in communication with the sensor system, the in-vehicle alert system and the remote haptic device, the control system operable to:
activate the in-vehicle alert system to provide at least one of an audible or a visual alert to the driver in response to a condition associated with the vehicle identified by the sensor system, and
if the driver does not respond to the at least one of the audible or visual alert, activate the remote haptic device to provide an alert to the driver.

2. The system as recited in claim 1 , wherein the remote haptic device is a watch.

3. The system as recited in claim 1 , wherein the remote haptic device is a key fob.

4. The system as recited in claim 1 , wherein the remote haptic device is a personal electronic device.

5. The system as recited in claim 1 , wherein the condition associated with the vehicle includes a condition around the vehicle.

6. The system as recited in claim 1 , wherein the lane monitoring device includes at least one of RADAR, SONAR, laser, LIDAR and an optical camera.

7. The system as recited in claim 1 , wherein the at least one of an audible or a visual alert is an audible alert.

8. The system as recited in claim 1 , wherein the at least one of an audible or a visual alert is a visual alert.

9. The system as recited in claim 1 , wherein the at least one of an eye monitoring sensor and a facial recognition sensor is an eye monitoring sensor.

10. The system as recited in claim 1 , wherein
the at least one of an eye monitoring sensor and a facial recognition sensor is a facial recognition sensor.

11. The system as recited in claim 1 , wherein the distance measurement device includes at least one of RADAR, SONAR, laser, LIDAR and an optical camera.

12. A method for alerting a driver of a vehicle, comprising:
identifying, with at least one of an eye monitoring sensor and a facial recognition sensor, whether the driver of the vehicle is impaired;
identifying, with a lane monitoring device, whether the vehicle is straying from a lane;
identifying, with a distance measurement device, a closing rate relative to another vehicle;
in response to at least one of an identification that the driver of the vehicle is impaired, that the vehicle is straying from a lane and of a closing rate relative to another vehicle, activating an in-vehicle alert system to provide at least one of an audible or a visual alert to the driver; and
if the driver does not respond to the at least one of the audible or visual alert, activating a remote haptic device carried or worn by the driver to provide an alert to the driver.

13. The method as recited in claim 12 , wherein the activating the remote haptic device includes vibrating.

14. The method as recited in claim 12 , wherein the remote haptic device is activated through a wireless communication.

15. The method as recited in claim 12 , wherein the at least one of an audible or a visual alert is an audible alert.

16. The method as recited in claim 12 , wherein the at least one of an audible or a visual alert is a visual alert.

17. The method as recited in claim 12 , wherein the at least one of an eye monitoring sensor and a facial recognition sensor is an eye monitoring sensor.

18. The method as recited in claim 12 , wherein
the at least one of an eye monitoring sensor and a facial recognition sensor is a facial recognition sensor.
